+CHAPTER I
+
+SPIES IN THE BOY SCOUT CAMP
+
+
+Gates, the United States Secret Service man, closed the door gently
+and remained standing just inside the room, his head bent forward in
+a listening attitude. Ned Nestor and Jimmie McGraw, Boy Scouts of
+the Wolf Patrol, New York City, who had been standing by a window,
+looking out on a crowded San Francisco street, previous to the
+sudden appearance of the Secret Service man, turned toward the
+entrance with smiles on their faces.
+
+They evidently thought that Gates was posing, as so many detectives
+have a silly habit of doing, and so gave little heed to the hand he
+lifted in warning. The boys knew little about Gates at that time,
+and so may be pardoned for the uncomplimentary thoughts with which
+they noted his theatrical conduct.
+
+Young Nestor had been engaged by the United States government to
+undertake a difficult and dangerous mission to South America, and
+Gates had been sent on from Washington to post him as to the details
+of the case. The boys had waited at the San Francisco hotel three
+days for the arrival of the Secret Service man, and waited
+impatiently, as Sam Leroy, who was to be the third member of the
+party, was anxious for the safety of his aeroplane, the Nelson, in
+which the trip to "the roof of the world" was to be made.
+
+The Nelson was lying, guarded night, and day, in a field just out of
+the city, on the Pacific side, and Leroy was impatiently keeping his
+eyes on the guards most of the time. There was a subconscious
+notion in the minds of all the boys that there were enemies about,
+and that the aeroplane would never be fully out of danger until she
+was well over the ocean on her way south. Gates had arrived only
+that morning, and now the lads were eager to be off.
+
+A couple of hours before his appearance in the room that morning,
+the Secret Service agent had left the boys in the lobby below to
+arrange for the necessary papers and funds for the mission. Before
+going out, however, he had been informed of the boys' suspicions,
+and had made light of the idea that the aeroplane was in danger from
+secret enemies, pointing to the fact that no one was supposed to
+know anything about the proposed journey save the boys and himself
+as conclusive evidence that the suspicion of constant surveillance
+was not well founded.
+
+Now, on his return, his cautious movements indicated that he, too,
+was alarmed and on his guard. While Ned was wondering what it was
+that had so changed Gates' point of view, there came a quick,
+imperative knock on the door of the room, which was occupied by Ned
+and Jimmie as a sleeping apartment.
+
+Instantly, almost before the sound of the knock died away, Gates
+opened the door and stepped forward. The man who stood in the
+corridor, facing the doorway, was tall, slender, dark of complexion,
+like a Spaniard or a Mexican. His black hair was long, straight,
+thin; his black eyes were bright, treacherous, too close together,
+with a little vertical wrinkle between the brows. He was dressed in
+a neat brown business suit of expensive material.
+
+When the door was opened he stepped forward and glanced into the
+interior of the room, apparently with the purpose of entering. But
+when Gates moved aside to give him passageway he drew back, the set
+smile on his face vanishing as he bowed low and swung his slender
+hands out in elaborate gesture.
+
+"Pardon!" he said. "I have made a mistake in the room."
+
+He was about to move away when Gates gritted out a question.
+
+"For whom were you looking?" he asked. "We may be able to direct you
+to your friend," he added, more courteously, his alert eyes taking
+in every detail of the man's face, figure and dress.
+
+"It is nothing!" was the quick reply. "I will make inquiries at the
+office--which, undoubtedly, I should have done before."
+
+In a moment he was gone, moving gracefully toward the elevator.
+Gates watched his elegant, well-dressed figure with a smile of quiet
+satisfaction. When the visitor gained the elevator, he turned and
+bowed at the still open doorway, and the Secret Service man
+recognized the grin on his face as expressive of triumph rather than
+apology.
+
+"What did he want?" asked Jimmie, as Gates, closed the door.
+
+Gates did not answer the question immediately. Instead he asked
+one:
+
+"Ever see that fellow before?"
+
+Jimmie shook his head, but Ned looked grave as he answered:
+
+"I have seen him about the hotel--frequently. He seems to have a
+suite off this corridor, or the one above it."
+
+At this moment the door was opened again and Sam Leroy bounced into
+the room, his eyes shining with enthusiasm, his muscles tense with
+the joy of youth and health. He drew back when he saw Gates, whom
+he had not met before, and looked questioningly at Ned.
+
+"This is Lieutenant Gates, for whom we have been waiting," Ned said,
+"and this, Lieutenant, is Sam Leroy, who is to take us to South
+America in his aeroplane."
+
+"I hope the machine is above reproach as to strength and speed,"
+laughed Gates, as the two shook hands cordially, "for there is
+likely to be doings down there."
+
+"The Nelson is warranted for work and wind," said Ned. "She crossed
+the continent in a rush and spied on us through British Columbia and
+on down the Columbia river, not long ago, and I can recommend her as
+a very desirable bird of the air."
+
+"She's all sound now," Leroy said, "but there's no knowing how long
+she will be if we don't get her out of San Francisco. There was a
+couple of men hanging around her last night, and one of them went
+away with a bullet in his leg. I'm glad you're here, Lieutenant,
+for now we can get away--quick!"
+
+"Did you get a good look at either of the two men you speak of?"
+asked Ned, his mind going back to what seemed to him to be a secret
+conspiracy against the Nelson.
+
+"One of them," Leroy answered, "was tall, slender, dark; with long
+straight hair and eyes like a snake. I noticed, too, that he had a
+habit of moistening his lips with the end of his tongue, and that
+made me think of a snake thrusting out his tongue. I got a shot at
+the other fellow, but not at this one."
+
+Gates and Ned looked at each other with nods of mutual
+understanding. This was a pretty good description of the man who
+had just stood before the door of that room. Then the lieutenant
+turned to Jimmie.
+
+"You asked a moment ago," he said, "what the fellow wanted here.
+Now I think I can tell you. He wanted to confirm his suspicions
+that the four of us axe working together. He has been sleuthing
+about the corridors all the morning, watching me; and his mission to
+this room was to make sure that my business in San Francisco is with
+Ned--that we are working together."
+
+"He's sure doing a lot of Sherlock Holmes stunts," Jimmie declared.
+"And I reckon he's next to his job, for he appears to have inspected
+all the points of interest, from the field where the Nelson is to
+the room where the plans are being made."
+
+"Yes," Leroy said, his manner showing apprehension as well as anger,
+"but how the Old Scratch did he get his knowledge, of what, we are
+about to do? I thought no one in the West knew except us four. And
+what's he trying to do, anyway? What difference does it make to him
+if we do go to South America in an aeroplane?"
+
+"I have a notion," Gates replied, "that he objects to your going in
+an airship because you will make such swift time. Let me tell you
+something more about this case. Then you will be able to understand
+why efforts may be made to prevent your going to South America, in
+an airship or in any other way."
+
+"It's just the airship they've been after so far," Leroy
+interrupted. "They haven't troubled us--and they'd better not!"
+
+"I imagine," said the lieutenant, gravely, "that their activities
+will broaden out as they get warmed up to their work. Understand?
+What I mean is this: You boys are risking your lives in undertaking
+this mission. You will be followed and spied upon from the minute
+you leave San Francisco, and the chances will be all against you
+when you reach your field of operations. Even the Government cannot
+protect you in your undertaking, for the Government is not supposed
+to know anything about this case."
+
+"We are to do something by stealth, then, which the diplomats of the
+State department are too cautious to undertake?" asked Ned.
+
+"That is it exactly," was the reply. "If the State department
+should take cognizance of the situation down there and make any sort
+of a demand, war would be certain to follow in case the demand was
+denied, which it would be. Therefore, the State department does not
+wish to make a demand. Still, the American who is in trouble must
+be protected. You are to go and get him out of his dungeon, or
+wherever he may be, and the Department of State will wink at what
+you do and look innocent."
+
+"Aw, why don't they send a warship to do the job?" demanded Jimmie.
+
+"Because," replied the lieutenant, "Uncle Sam has taken the
+republics of South America under his protection, and he does not
+care to spank them in the presence of all the nations of the earth!
+He wants to get this man Lyman--Horace M. Lyman, to be exact--out of
+the clutches of a crooked gang in Paraguay without wasting money and
+lives. Hence the arrangement with you boys."
+
+"I have read something about the Lyman case," Ned observed, "but I
+have forgotten all the material points, I guess."
+
+"Lyman," Gates went on, "took up his residence in Paraguay some
+years ago and opened negotiations with the government for a cattle
+concession. The lands known as the 'Chaco' district, lying between
+the Paraguay and Pilcomayo rivers, are said to be the best for
+grazing purposes in all South America. Years ago they were
+considered worthless swamps, but this is all changed now.
+
+"Well, Lyman entered into negotiations with the president of this
+alleged republic and got his concession. There is no knowing how
+much he paid for it, for every new president of Paraguay--and they
+have new ones quite frequently down there--seems to do business on
+the theory that what he doesn't get while the getting is good he
+never will get at all. There have been four or five new official
+heads of this alleged republic within a couple of years.
+
+"The country is on the verge of revolution most of the time and as
+the army goes so goes the election. Jara was made prisoner last
+July, and one Rojes put in power. Now, in order to keep in good
+standing with the army, the government is obliged to have generals
+who are loyal to whoever is in power. These generals must be paid
+for their services, of course.
+
+"It seems that Lyman fell under the displeasure of one of these
+powerful military chaps, probably because he refused to give up all
+his profits in the cattle business. Anyway, Lyman disappeared from
+home, quite suddenly, and his manager was notified that settlement
+could be made with one Senor Lopez, an army chief, said to be a
+relative of a former president. So Lopez was appealed to.
+
+"Now Lopez is a slippery chap. He denied knowing anything about
+Lyman, but declared that unless the cattleman appeared shortly and
+took up his work on the cattle concession the grant would be taken
+from him. That is like South American justice. Lock a man up and
+then deprive him of his rights because he can't appear and claim
+them!"
+
+"Must be a fine healthy country!" Jimmie interposed.
+
+"It is all of that," laughed the lieutenant. "Then this manager, I
+think his name is Coye, appealed to the United States consul and the
+consul to the president. Nothing doing! Lyman, they insisted, had
+not been molested by the authorities. But Lyman's people in this
+country are kicking up an awful row, and something must be done.
+
+"There is no doubt that the cattleman, is locked up in some of the
+old military prisons of the country, yet the State department can't
+get him out. The president offers any assistance in his power, of
+course! Lopez weeps when the matter is mentioned to him--weeps at
+the unfounded suspicions which are being cast upon him! So there
+you are! The only hope for Lyman lies in some such method as has
+been planned. If you fail, the situation will be desperate,
+indeed."
+
+"Why don't Lyman buy the fellow off?" asked Jimmie.
+
+"The purpose of Lopez in pursuing the course referred to is
+undoubtedly to find an excuse for robbing Lyman of the concession
+and selling it to another at a much greater price. So others
+besides the general and Lyman are concerned in this mix-up."
+
+"You refer to a person, or corporation, waiting to buy the
+concession?" asked Ned, the reason for the surveillance in San
+Francisco coming to him like a flash.
+
+"That is it."
+
+"And these prospective concessionaires are looking to it that Lyman
+gets no aid from this country?"
+
+"I had not looked at the matter in that way, had not thought of
+their venturing over here, but presume you are right."
+
+"Look here," Leroy asked, "are you figuring it out that the people
+who are trying to steal or cripple the Nelson came here from
+Paraguay for the express purpose of watching this Lyman case and
+preventing his friends from assisting him?"
+
+"You state the case in a way which gives it a good deal of
+importance," Gates replied, "But I believe you state it correctly.
+Just how the men who hope to gain the concession if Lyman loses it
+came to understand the attitude of our Government is more than I can
+imagine, but it is quite clear to me that they do understand the
+situation--that they are thoroughly posted as to every move that has
+been made by the Government and by the friends of the cattleman."
+
+"It is a good thing to know that we are likely to be chased to South
+America," Ned said, "for we know exactly what to expect, and shall
+be on our guard."
+
+"Chased to South America!" laughed Leroy. "They'll have to go some
+if the keep up with the little old Nelson! She can fly some--if you
+want to know!"
+
+
+
+
+
+CHAPTER II
+
+A FOX JOINS THE WOLVES
+
+
+Nelson hung like a great gull over New Orleans one hot morning in
+early August. The boys who occupied seats on the light aluminum
+form under the sixty-foot wings glimpsed the Gulf of Mexico in the
+distance, while directly their feet ran the crooked streets of the
+French Quarter.
+
+The departure from San Francisco had been for a delayed for a long
+time because of the non-arrival of important instructions from
+Washington, and because of a slight injury to the aeroplane while
+out on what Leroy called an "exercise run." Lieutenant Gates had
+remained with the boys until they started on their long flight to
+the mouth of the great Mississippi river, and had then returned to
+Washington.
+
+I had first been the intention to proceed due from San Francisco,
+then wing toward the east where the coast of Peru showed. This plan
+was opposed by the lieutenant, for the reason that an airship far
+out on the Pacific ocean, directly in the steamship route, would be
+likely to attract attention sailing over the southwestern states and
+Central America. Daring aviators now venture in all directions and
+at all altitudes above the solid earth, but they are still cautious
+about proceeding far out over the merciless waters of the oceans
+which rim the continent of North America.
+
+So, yielding to the wishes of the lieutenant, the Nelson had been
+directed by her navigators across California, Arizona, New Mexico,
+Texas and Louisiana until the great city of the South lay spread out
+before them. The distance covered by the airship in this flight was
+not far from thirty-five hundred miles, and the Nelson, leaving the
+coast city on Monday morning, August 7, had covered the run so as to
+reach New Orleans late Wednesday afternoon.
+
+The boys might, it is true, have speeded up and made the distance in
+thirty-six hours, or less but they realized the necessity of taking
+good care of themselves, and so they had rested in quiet places both
+Monday and Tuesday night, landing about midnight and sleeping until
+long after daylight. Having provisions with them, they had not
+found it necessary to land except when gasoline was obtained at
+Santa Fe.
+
+The machine had attracted little attention on the route, for it was
+painted a dull gray, and its aluminum motors gave forth little
+sound. It was two merits of the machine, which had been invented by
+young Leroy, that it could navigate in a clear sky a mile up without
+being observed from below, and could also run to within a short
+distance of the earth without making herself conspicuous by the
+popping of her motors. The United States authorities are now
+adapting these two qualities to the government airships to be used
+in the military service.
+
+The boys remained in New Orleans until Thursday morning, August 10,
+and then, with full provision baskets and gasoline tanks, they set
+out across the Gulf of Mexico. They soon sighted Yucatan, which is
+really a province of Mexico, darted over British Honduras, and swung
+over the forests of Guatemala, the one country in Central America
+which is never bothered with revolutions.
+
+When an ambitious person wants to wrest the reins of government from
+the officials in charge, they take him out and stand him up against
+a stone wall, with a firing squad in front. This manner of
+preventing revolutions is believed to be conducive to peace and also
+to the sanctity of human lives. Jimmie, who had been reading up on
+South and Central America while waiting in San Francisco, explained
+many points of interest as the Nelson sped on her way.
+
+They took on more gasoline at Panama, and Ned and Jimmie were very
+glad to renew their acquaintance with that now model city. Those
+who have read the former books of this series will remember that the
+Boy Scouts at one time had a commission to stand guard over the
+great Gatun dam.
+
+They did not remain long in Panama, however, as they were anxious to
+get to the scene of their future operations. They were all
+anticipating great fun in exploring "the roof of the world," which
+extends from Colombia to Argentina, north and south, through
+Equator, Peru, and Bolivia, more than 2,000 miles, or as far as from
+New York City to Denver. In many directions from this "roof" may be
+seen villages, cattle, sheep, llamas, and evidences of mining.
+
+The boys made good progress down the coast of tropical South
+America. They had heard much of Peru, and were surprised to see
+only a great strip of sand, lying like a desert, between the Pacific
+and the mountains. Now and then a little stream, fed by the melting
+snows in the Andes, comes trailing out toward the sea, but it is
+usually smaller at its mouth than at its source for the reason that
+the precious water is utilized for irrigation purposes. Wherever
+there is water crops grow luxuriantly.
+
+Thus far they had not been molested in any way. Indeed, considering
+the speed with which they had traveled, it would have been difficult
+for any one to have meddled with their plans. They were therefore
+in excellent spirits when they landed at Lima, which is the one
+large city of the country.
+
+Lima, however, is not built on the coast, Callao being the seaport
+of the metropolis. Lima is a modern city in every way, with,
+handsome streets, electric lights, and all that any modern city has
+in the way of amusements.
+
+The Nelson was anchored on the morning of August 14, in a
+sequestered spot, and the boys, after answering many foolish
+questions, laid plans to look over the wonderful city. It was
+necessary to station a strong guard about the machine, for the
+natives--many of whom spoke the English language fairly well--were
+overly curious concerning the man-made bird.
+
+In answer to all questions as to their plans, the lads replied that
+they were seeking the headwaters of the Amazon, and would soon pass
+over the Andes and drift down into Brazil. This was not far from
+the actual truth, as it really was the Intention to return home by
+that route after their mission had been accomplished.
+
+"But the wind is always from the east," was often urged against this
+plan, as explained by Jimmie, who lingered about the Nelson while
+the others were at the hotel.
+
+When it was explained to the doubters that the Nelson was capable of
+making a hundred miles an hour against a stiff breeze, the natives
+seemed to doubt the veracity of the boys. The Peruvians knew little
+of airships, and when Jimmie exhibited to them daily newspapers
+showing how Germany was building a fleet of three hundred airships
+to use in case of war, they still looked incredulous.
+
+"Look here, fellers," Jimmie explained to them, later in the
+afternoon of the arrival, as a group of curious ones stood about the
+roped-in enclosure where the Nelson lay, "I guess you don't know
+much about the navigation of the air. It used to be risky; now it
+is no more so than riding on a railroad train."
+
+"You say it well!"
+
+The words were spoken in good English, seemingly in a boy's voice,
+and Jimmie peered through his audience in order to catch a glimpse
+of the speaker. Presently, above the heads which surrounded him,
+the boy saw a hand and arm extended. The palm was out, the thumb
+and little finger flat and crossed, the three remaining fingers held
+straight out. The full salute of the Boy Scouts.
+
+"Say, you!" the lad cried out, greatly pleased at finding a Boy
+Scout there. "Where did you get that?"
+
+"Scouted for it!" was the reply.
+
+"What does it read?"
+
+"Be prepared!"
+
+"Where from?" was the next question.
+
+"Fox Patrol, Chicago."
+
+"You must be pretty foxy," Jimmie laughed, "to get away off here."
+
+The member of the Fox Patrol now made his way through the crowd and
+extended a hand to Jimmie.
+
+"You don't look as if it paid to be a Fox," laughed the latter.
+
+The boy certainly did look like a tramp. He was a lad of about
+sixteen, well formed as to figure and attractive as to feature, with
+bright blue eyes, long, fair hair, and a complexion which would have
+been perfect only for the grime upon it. He blushed as Jimmie
+looked him over, and involuntarily turned his eyes down to his
+ragged clothing and broken shoes.
+
+"Forget that!" Jimmie cried, in a moment. "I didn't mean anything
+by it. Where you stopping?"
+
+The fact was that Jimmie suspected from the appearance of the lad
+that he was hungry as well as ragged and dirty. He certainly looked
+hungry. The boy hesitated before replying, his hands deep in his
+trousers pockets, his eyes on the ground. Then a whimsical smile
+came to his face and he looked Jimmie squarely in the face.
+
+"No use of lyin' about it," he said. "I'm stoppin' down here at the
+Blue Sky Hotel. It's a dandy place to stop at. They never present
+a board bill."
+
+Jimmie sat back on the rope which was drawn about the Nelson to keep
+meddlesome ones away from the machine and burst into a roar of
+laughter. The crowd looked on stupidly, glancing from boy to boy,
+and then at one another, as if wondering if these Americans always
+went crazy when they met in a foreign land.
+
+"I know that Blue Sky Hotel," Jimmie said, presently, "though I've
+never heard it called by that name before. I had a room in one, in
+Central Park, New York, until a sparrow cop drove me out of it. I
+liked it because I didn't have to dress for dinner there," he added,
+whimsically.
+
+"The feed is rather slim," observed the other.
+
+"It's run on the European plan," grinned Jimmie. "You get your
+sleepins, an' no one cares whether you get your eatin's or not.
+What's your name?"
+
+"Dougherty--Mike Dougherty, Clark street, south of Van Buren!"
+
+"I guess you must be French," Jimmie grinned.
+
+"You've guessed it. Now, what's your name, and what are you boys
+doin' here with this old sky-ship?"
+
+"I'll tell you all about it when we get back to the hotel," Jimmie
+replied. "Do you know any of the gazabos about here? I want some
+one to watch the ginks who are watchin' the mutts who are watchin'
+the aeroplane."
+
+Dougherty laughed at this suggestion of a treble surveillance and
+pointed out a lanky looking individual who was studying the machine
+closely from the outer side of the roped-circle.
+
+"That's Pedro," he said. "He's all right. About all I've had to
+eat since I came here he's given me. He's a Peruvian Indian, and in
+need of money. Give him a dollar, and he'll guard your guards a
+month, and never leave the machine, night or day."
+
+"Does he talk United States?"
+
+"Oh, just a little."
+
+Pedro talked quite a little United States, as Jimmie called it, and
+a bargain was soon struck with him. Then the two boys started away
+together. First they visited a clothing store, where Jimmie looked
+at the best suits in stock, and measured Dougherty cautiously with
+his eyes. A full outfit of under and outer clothing provided, they
+proceeded to the hotel, where Jimmie ushered his new-found friend
+into a commodious bathroom.
+
+"Remove some of your real estate," the boy said, "an' hop into these
+new clothes. They ain't very nobby, but the best I could get here."
+
+Mike Dougherty stood looking at Jimmie for a moment as if he could
+not believe what he heard. It had been a long time since he had
+been clean and properly clothed. Then there came a suspicious
+moisture to his keen eyes and he turned away.
+
+"Oh, well," he said, with a tremble in his clear young voice, "mebbe
+I'll be able to pay you back some day. Just now I'm--"
+
+"Cut it out!" Jimmie replied. "You hain't got anythin' on me. I've
+been there meself, an' the Boy Scout that helped me out told me to
+pass it along. That's what I'm doin' now, and there's nothin' more
+to be said. When you get washed and dressed, come on to No. 4,
+that's the second room from this tub, on the left of the corridor,
+an' I'll show you the rest of the bunch."
+
+Jimmie went away to No. 4, where Ned and Sam Leroy were waiting for
+him. Somehow, it seemed to Ned that Jimmie kept him waiting about
+half the time when they were in a strange city. The little fellow
+had a way of wandering off alone and forgetting all about time in
+his delight at the strange things he saw. When he entered No. 4 he
+found Ned standing near the door.
+
+"Were you out there before?" Ned asked, pointing to the corridor, as
+Jimmie stepped inside.
+
+"Just got here," was the reply. "Found a Boy Scout from the Fox
+Patrol, Chicago, an' brought him along with me. He's washin' some
+of the Peruvian scenery off his frame, now, an' will soon be along."
+
+Then Jimmie told of his discovery of Mike Dougherty, of his leaving
+a treble guard around the Nelson, and of numerous other adventures
+in the city, which, not being in any way connected with this
+narrative, are not set down here.
+
+"I'm glad you brought this boy Mike here," Ned said, at the
+conclusion of the story. "We need some one who knows something
+about Lima to keep us posted."
+
+"About what?" asked Jimmie.
+
+"We're spotted!" Leroy cried out, before Ned could answer the
+question. "The wireless is swifter than the Nelson!"
+
+"How do you know?" demanded the little fellow. "How do you know
+we're spotted?"
+
+"Oh, Ned's been doping it out," was the reply. "He'll tell you, I
+guess."
+
+"You thought you'd take the cream off the sensation!" laughed Ned.
+"Well, that is the boy of it! All I know about it, Jimmie," he
+continued, "is that I've been receiving telegrams which simply mean
+nothing. They are from people I have never heard of, and are most
+mysteriously worded."
+
+"There's one that tells you to get out of the country," suggested
+Leroy.
+
+"Yes, but the others seem to infer that the man who sent them is out
+of his mind. The three received are from Washington, San Francisco,
+and New Orleans."
+
+"What have the messages to do with our being spotted?" asked Jimmie.
+"I don't see any connection."
+
+"Stupid!" cried Leroy. "Can't you see the wires were sent to locate
+Ned? The person who delivered them to him sure wired back that they
+had been delivered to Ned in person--in other words, that he has
+reached Lima on his journey to Paraguay."
+
+"I see!" Jimmie said, slowly. "It's clever, eh?"
+
+"Too clever," Ned said. "I don't like the looks of it. It means,
+of course, that the people who are trying to get the cattle
+concession away from Mr. Lyman have secret agents here. And that
+means that everything we do at Lima will be watched and reported."
+
+"Reported to whom?" asked Leroy.
+
+"Probably to this military person, Senor Lopez, who is on the job
+with both hands out," suggested Jimmie. "Well? What about it?"
+
+"I think," Leroy cut in, "that we'd better be getting out of this.
+They can't follow us after we get up in the air."
+
+Here a knock came on the door, and Jimmie admitted Mike and
+presented him to his chums. The boy looked trim and handsome in his
+new suit, and all took a great liking to him. While they discussed
+their plans another interruption took place, and then Jimmie saw
+Pedro at the door, beckoning excitedly to Mike Dougherty. The boy
+talked with the Indian for a short time, and then turned to Ned,
+excitement showing in his face.
+
+"He says there's another airship here," Mike said. "Prowling over
+the mountains."
+
+"They can't follow us in the air, eh?" cried Leroy. "I guess this
+is going some!"
+
+
+
+
+CHAPTER III
+
+BLACK BEARS ON THE AMAZON
+
+
+The handsome club room of the Black Bear Patrol, in the city of New
+York, was situated on the top floor of the magnificent residence of
+Attorney Bosworth, one of the leading corporation lawyers in the
+country. Jack Bosworth, the lawyer's only son, was a member of the
+Black Bear Patrol, and the club room had been fitted up at his
+request.
+
+It was in this room that Ned Nestor, Jimmie McGraw, Jack Bosworth,
+Harry Stevens, and Frank Shaw had planned their motor-boat trip down
+the Columbia river, as described in the first volume of this series.
+Jack, Harry and Frank had returned to New York from San Francisco
+when Ned had decided to accept the Secret Service mission to
+Paraguay, at the conclusion of the motor-boat vacation on the
+Columbia, leaving the two boats, the Black Bear and the Wolf, stored
+at Portland, Oregon.
+
+One evening--the evening of the 1st of August, to be exact--while
+Ned, Sam, and Jimmie were still in San Francisco, awaiting the slow
+action of the State department at Washington, Jack, Frank and Harry
+met in the club room for the purpose of "sobbing together," as they
+expressed it. They had left their friends in San Francisco
+reluctantly because of orders from home, and now they understood
+that they might have gone with Ned and Jimmie if they had only
+explained to their parents the purpose of the mission.
+
+"I suppose," Frank Shaw said, at the end of a long pause in the
+conversation, "I suppose Ned and the others are out over the Andes
+by this time."
+
+"No," replied Jack. "I heard from Jimmie by wire today, and they
+are still in Frisco, and likely to remain there nearly a week
+longer."
+
+"If the airship was only large enough!" sighed Harry.
+
+"We might still get there in time!" Frank suggested, eagerly.
+
+"The Nelson wouldn't carry us if we were there," Jack exclaimed, in
+a disgusted tone. "I wish the Black Bear had wings! Say, wouldn't
+that be a peach? We could run over to Paraguay and scare the life
+out of the boys!"
+
+"What good would it do if she had wings?" demanded Frank. "She is
+in storage at Portland, Oregon."
+
+"No," replied Harry Stevens, whose father, a noted maker of
+automobiles, had presented the motor-boats to his son, "I ordered
+the boats sent on here the day after we left the coast. We can
+take a trip up the Hudson, anyway."
+
+Jack walked thoughtfully around the room for a moment and then
+turned back to the others, looking moodily out of a window.
+
+"I've got it!" he shouted, slapping Frank on the back.
+
+"I should say you had!" remarked Frank. "What do you take for it?"
+
+"I say I've got an idea!" Jack explained, jumping up and down and
+swinging his hands over his head. "A peach of an idea!"
+
+"Does it hurt?" asked Harry.
+
+"Oh, cut out that funny stuff!" Jack cried. "When will the two
+motor-boats be here?"
+
+Harry counted on the fingers of his left hand.
+
+"We've been home two days," he said, "and we were four days getting
+to Chicago. There we laid over a day, and came on here in twenty
+hours. We are eight days from the Pacific coast. That right?"
+
+"It seems to be."
+
+"Well, then, it is seven days since I ordered the Black Bear and the
+Wolf sent on here in a special express car. They ought to be here
+now."
+
+"Then," shouted Jack, pulling Harry around the room, "we're all
+right--fit as a brass band at a free lunch! Whoo-pee!"
+
+"It must be hungry," Frank exclaimed, regarding Jack with seeming
+terror. "Does it ever bite when it puts out these signals of
+distress?"
+
+"Don't get too funny!" Jack warned.
+
+"Then loosen up on this alleged idea!" Frank replied.
+
+Jack rushed across the room and brought out an atlas of the world,
+which he dumped on the floor and opened.
+
+"Look here, fellows!" he said, squatting over the map of South
+America, his chin almost on his knees.
+
+"We're looking," grinned Frank. "What about it?"
+
+"Here we are in New York," Jack went on. "Here they are in San
+Francisco. Now, they've got to sail to Paraguay, which is just
+about twice as far from San Francisco as is New York. Anyway,
+that's the way it looks on the map."
+
+"It is all of that distance," Harry put in.
+
+"Well," Jack continued, "as I said before, here we are in New York,
+with the mouth of the Amazon river about as far away as San
+Francisco, perhaps a little farther."
+
+"Well?" demanded Harry.
+
+"I begin to see the point!" Frank admitted. "But will the folks
+stand for it?"
+
+"Mine will," Harry answered. "Dad didn't make the Black Bear to lie
+in storage. He'll stand for it, all right."
+
+"So will mine," Frank said, then. "I'll tell him I'll send him a
+lot of news for his paper."
+
+Frank's father was owner and editor of the Planet, one of the
+leading morning newspapers in the big city, and it was always a
+fiction of the boy's that he was going out in the interest of the
+paper when he wandered off on a trip with the Boy Scouts.
+
+"I'm afraid you can't make that work again," laughed Jack. "Ned
+says that you sent only four postal cards and six letters back from
+Panama."
+
+"Well, wasn't that going some?" asked Frank.
+
+"Of course, only Ned says the postal cards carried the
+correspondence for the Planet, and the letters carried requests for
+more money!"
+
+"Anyway," Frank insisted, "Dad will stand for it. What is it?"
+
+"Well," Jack went on, "I'm sure my Dad will let me go. He wants me
+to go about all I can. Says it brightens a fellow to rub up against
+the rough places of the world."
+
+"There's rough corners enough in South America," laughed Harry.
+
+"Now, let us get down to figures," Jack continued. "We ought to be
+able to get to the mouth of the Amazon on a fast boat, with the
+Black Bear and the Wolf on board, in a week or ten days-say ten
+days. About that time they will be getting into Paraguay. What do
+you think of it?"
+
+"Fine!" cried Harry.
+
+"The best ever!" Frank responded. "But what then? We can't run up
+to Paraguay in the Black Bear."
+
+"We can get away up in the Andes," answered Jack, with the map of
+Brazil before him. "See these crooked little lines? Well, those
+are rivers. Just see how far we can go in a motor boat."
+
+"But that won't bring us to the aeroplane," Frank objected.
+
+"Yes, it will," Harry answered. "They are coming back by way of the
+Amazon valley, and we can't miss them. Oh, what's the use? Suppose
+we begin packing?"
+
+"Well, I don't know exactly what we are to do after we get up the
+Amazon," Harry laughed, "but I'm game to go. There are head-hunters
+and cannibals up there, and we may find a little amusement."
+
+"We're going after Ned and Jimmie," Jack explained. "This is a
+relief expedition! After they get to Paraguay they'll snatch that
+Lyman person out of the cold, damp dungeon keep he is supposed to be
+in and then sail off over the Amazon valley. There's where we catch
+up with them. Do you suppose we can find a ship going to the mouth
+of the Amazon early in the morning?"
+
+"You certainly are fierce when you get started!" laughed Harry.
+"Well," he added, "you can't get ready any too soon to please me."
+
+It was two days before the boys found a vessel going their way, and
+even then Jack insisted that his father bribed the owners to run off
+their course in order to set the boys and their motorboats down at
+the mouth of the Amazon river. The boat, however, was a fast one,
+equal in speed to a modern ocean liner; and in ten days from the
+time of starting from New York--on the 12th of August--the boys were
+stemming the current of the great river--more like a shoreless sea
+there at the mouth than a river!
+
+"Huh!" Frank exclaimed, as they left the island of Joannes to the
+south, "this is no river! It is a blooming sea!"
+
+"Pretty near three hundred miles wide at the delta, including that
+big island," Harry said. "It is some river, eh?"
+
+"Four thousand miles long!" Jack contributed. "It is navigable for
+commercial purposes for 2,200 miles, and our boats can go up clear
+to the foot of the Andes."
+
+"Boats went there in the days of Columbus," Frank said. "A
+companion of Columbus first discovered this great delta. The river
+fertilizes two million square miles of territory, and is the
+greatest water system in the world."
+
+"Why," Harry observed, desiring to contribute something startling to
+the discussion of the river, "the current is so strong that it
+carries fresh water and sand five hundred miles out into the
+Atlantic Ocean. It is just a fresh water river in a salt water sea
+for five hundred miles!"
+
+That night the boys kept the engines of the Black Bear going, one
+remaining on watch all through the dark hours. They had plenty of
+gasoline in the tank, and the tender, the Wolf, was carrying a load
+of fuel which Jack declared would last them until the end of the
+year!
+
+It may be well to state here that the Black Bear, the Boy Scout
+motorboat, was a specially constructed vessel, built by Harry's
+father for river work. The materials were light yet strong, and the
+boat could easily be taken apart and put together again when
+occasion required. Between the cross-grained slices of tough wood
+of which the craft was built were plates of steel, thus rendering
+the boat virtually bullet proof.
+
+The Black Bear was constructed so that it could be almost entirely
+thrown open to the sunshine when so desired or closed tightly
+against cold or rain. The roof could be rolled up in a bundle in
+the middle like the curtain of a modern desk. The sides were
+composed of oblong panels which could be inserted in grooved steel
+uprights when it was desired to close in the interior of the boat.
+The motors were very powerful.
+
+In fact, it was just such a boat as was needed on the trip the boys
+had in mind. It had done excellent service on the Columbia, and
+nothing less could be expected of it on the Amazon. The Wolf, which
+was merely a tender, was watertight in construction, being shaped
+like a banana, and was towed by the motor-boat. Here the extra
+stocks of gasoline, provisions, and ammunition were packed. The
+interior of the Wolf was about six feet by eighteen in size, while
+the distance from rounded floor to convex roof was about four feet.
+
+On both sides of the interior were gasoline tanks, which also
+extended under the floor, lifting the bottom of the interior space
+three feet. Above the tanks were spaces for provisions and
+ammunition. The space between the tanks and the lockers was about
+two feet, and here one might ride in comfort, after getting used to
+the rolling of the boat. There were tight glass panels of thick
+plate glass at the ends and the top.
+
+Ventilators and loopholes, controlled by wires from the center, were
+cut in the ends and protected by sliding covers. Lying in the
+passageway, one might look out at either end, and shoot out, too, if
+occasion required. When fully loaded, the Wolf was submerged about
+half its height. On the top was a staff from which floated an
+American flag. The boys were very proud of the Wolf, and Jimmie had
+often declared, on the Columbia river trip, that he would some day
+take an exciting ride in it.
+
+During their passage up the river the boys were often hailed from
+passing craft, but they took little heed, as they did not care to
+lose time gratifying the curiosity of those they met. Indeed, if
+they had stopped to talk with all who hailed them, they would have
+made slow progress. Up to about sixty years ago the Amazon was
+closed to all save Brazilian vessels, but now it is open to the
+commerce of the world.
+
+There are now vessels coming from and going to all parts of Europe
+and America from Amazon ports. There are lines of great steamers on
+the main stream, lines of smaller steamers on the big tributaries,
+and launches and small craft of all sizes on the affluent branches.
+Often the passing ships, steamers, launches, etc., almost took the
+form of a procession on the lower waters.
+
+Everywhere the smaller ships were gathering the products of the
+great Amazon basin-rubber, cocoanuts, hardwoods, dyewoods, pelts,
+tropical fruits and other commodities. Every year over three
+million tons of products come down the great river. The Amazon
+drains a country as large as the United States east of the
+Mississippi. Its feeders reach the Andes, draining watersheds
+within a hundred miles of the Pacific ocean. It has tributaries
+fifteen hundred miles long.
+
+It did not take the Black Bear very long to pass the green islands
+near the delta. The river there looks like an ocean. In fact, the
+main branch of the Amazon is from fifty miles to two hundred miles
+in width. Some of the tributaries are a hundred miles wide. It is
+from fifty to two hundred feet deep. The water is always dark
+colored because of the wash brought down from the uplands. For a
+long time it did not seem possible to the boys that they were
+sailing on a river instead of an ocean.
+
+"Ned and the boys must be over Paraguay now," Jack said, one day,
+after they had been on the river nearly a week without accident or
+important incident of any kind.
+
+"Yes," Frank replied, "they must be there by this time. Jimmie said
+they were to leave San Francisco on the 7th, or about that time. It
+would take a week or more to get to Lima, for they couldn't remain
+in the air long at a time, and the resting spells would set them
+back a little. Suppose they got to Lima on the 14th, which was last
+Monday, they could rest up and go prowling over that dirty little
+republic--which is not a republic at all, but a despotism tempered
+by revolution."
+
+"I'd like to know just what course Ned has decided on," Harry said.
+"I don't see how he's going to get to Mr. Lyman."
+
+"He'll find a way," Jack insisted. "He always has, and he always
+will."
+
+It will be seen that the boys were tolerably accurate in their
+estimates of the speed of the Nelson. On the day they were
+discussing the possible location of the big airship, which was the
+18th of August, the Nelson was in the center of as pretty a muss as
+Ned had ever mixed with.
+
+The boys in the Black Bear put on all speed, traveling nights as
+well as days, and before long began watching the heavens, for an
+aeroplane. But the lads on the Nelson were not looking for a boat
+poking her nose toward the Andes--"a relief expedition," as Jack
+called it!
+
+
+
+
+CHAPTER IV
+
+A CHASE IN THE NIGHT
+
+
+Following the excited announcement by Mike that an airship was
+prowling about over the mountains and Leroy's sudden cry of
+exultation at the prospect of a struggle for supremacy above the
+clouds, there was for a moment absolute silence in the hotel room
+where the boys stood. Finally Pedro entered and closed the door.
+
+Ned walked to a window and looked out. The day was fading, and
+already the feet of the distant mountains were wrapped in purple
+twilight. The window faced the north, giving a fair view of the
+city and the Andes as they strung along in that direction, looking
+like a chain of bald heads lifting from the obscurity of a fog. The
+airship was not in sight from where he stood.
+
+Pedro saw what he was looking for and stepped to his side, one hand
+pointing off to the east.
+
+"Out there!" he said.
+
+"When did you first see it?" asked Leroy, not waiting for Ned to
+conduct the cross-examination.
+
+The Indian talked with Mike for a moment.
+
+The latter did not seem to understand all that was said to him, but
+presently he turned to Ned.
+
+"He says he saw it only a minute before he came here," he explained.
+"He says a lot more that I can't understand. I've been here only a
+month, and I'm not quick at learning new speech."
+
+"Ask him if he knows whether she landed anywhere near the city," Ned
+directed.
+
+The Indian did not know. The airship was over the mountains when he
+first saw it, and that was all he could say about it.
+
+"Do you think we've been followed down here?" asked Jimmie.
+
+"Of course!" Leroy broke in. "What else would an airship be here
+for just at this time? And if she wasn't sneaking about after us,
+what would she be hanging up there in the sky for? Why doesn't she
+come down to town, like we did?"
+
+"It may be that the arrival of this airship just at this time is a
+coincidence," Ned said, "but it seems to me that there is something
+significant about it. I have felt all along that we were not yet
+rid of the rascals who tried to make us trouble at San Francisco."
+
+"Some one must want the cattle concession that Lyman has pretty
+badly," Leroy ventured. "Well, we'll, have to run away from them, I
+take it!"
+
+"Then how are we going to find out where this Lyman person is?"
+demanded Jimmie. "No, Sir!" he went on, rubbing his freckled nose
+in meditation. "We've just naturally got to bust 'em up!"
+
+The proposition was indeed a serious one. If the airship was really
+there to take note of the activities of the boys on the Nelson, the
+situation could hardly be improved by following either line of
+conduct suggested by the boys.
+
+Nothing could be gained by "running away" from the unwelcome
+visitor. Nothing was to be gained by following the advice to "bust
+'em up." A race would only serve to draw the Nelson away from the
+point of action, away from the place where Lyman was held in
+captivity. To "bust 'em up" would be to set all the official rings
+of Paraguay in operation against the lads, place the Boy Scouts
+under the ban of the law!
+
+"If we only knew just where to find this Lyman person," Jimmie went
+on, "we might swoop down an' get him an' give the lobsters a run for
+their money."
+
+"Perhaps," Ned suggested, "we'd better wait for this new navigator
+of the air to show us where he is."
+
+"I see him doing it!" cried Leroy.
+
+"You bet he will!" Jimmie cut in. "He'll hang around the point of
+danger! He'll show us where the man is by standing guard over him!
+What?"
+
+"That's my idea," Ned replied, "still, he may devote his energies to
+keeping track of us. One can never tell what an enemy will do."
+
+"Well," Leroy said, "I'm going back to the Nelson. There's a chance
+of the lobster dropping down and trying to cripple her."
+
+"A very good idea," Ned agreed.
+
+Jimmie and Mike hastened away with Leroy, but Pedro remained at the
+request of Ned. A plan for meeting the emergency was already
+forming in the active brain of the Boy Scout, and an important
+detail depended on information which the Indian might be able to
+give.
+
+Before opening the question, however, Ned, motioning to the Indian
+to follow, made his way to the flat roof of the hotel building.
+There he found several men, smoking, chatting, and watching the
+airship, now almost directly over the city. In Peru many houses are
+built with especial reference to providing a lounging place on the
+roof.
+
+It was growing darker, and the lights of the airship shone brightly
+against the dimming sky. The aviator was now circling around the
+city, dropping lower at times, then skimming in spirals to a higher
+point. While Ned stood watching the machine, realizing that the
+fellow in charge was no novice in aviation, a gentleman whom he had
+noticed three times before that day observing him closely advanced
+and stood by his side. He was a well dressed, clean-shaven man of
+perhaps thirty, with an intelligent face, a bustling manner, and a
+suit of clothes which Jimmie would have described as "loud enough to
+lead a circus parade."
+
+"Evidently an American commercial traveler," Ned thought, as the
+stranger stood by his side a moment without speaking, his eyes fixed
+on the airship.
+
+"She goes some, eh?" the stranger observed, presently.
+
+"The aviator seems to know his business," Ned admitted.
+
+"You came in an aeroplane yourself, didn't you?" asked the other.
+
+Ned answered in the affirmative.
+
+"Thought so," the other went on. "Hadn't seen you about the city
+until this afternoon, and some one said you came in an airship.
+Where from?"
+
+"New York," Ned replied, half amused at the impertinence of the
+question.
+
+"Good old town!" the other exclaimed. "Hot old town! I like it.
+There's something always going on there. I'm from New York myself,
+but I'm selling goods for a Chicago firm--steam pumps! I've got the
+best steam pump in seven countries! Came here to sell to a mining
+company. Nothing doing. What's your name? Mine is Thomas Q.
+Collins."
+
+"Nestor," Ned replied, shortly.
+
+"And you're out for fun?"
+
+"That's the idea." Ned did not think it necessary to enter into
+details.
+
+"Hope you get all that's coming to you! Say, will you give me a
+ride in that machine of yours? I went out to see it today. Looks
+to me like it could knock the spots off anything of the kind in the
+world. I don't know anything about airships, but I do know about
+steam pumps, and also about machinery. I know a good piece of work
+when I see it. That boat of yours is a peach!"
+
+"It isn't my machine," Ned replied, "but if we remain here over
+tomorrow I'll see about granting your request."
+
+The two talked for a moment longer, and then Collins left the roof.
+Later, Ned saw him moving through the street below in the direction
+of the place where the Nelson had been left. The boy hardly knew
+what to make of Collins. He might be a steam pump salesman, just as
+he had described himself, and, again, he might be a spy sent out by
+Lyman's enemies to discover the plans of the Boy Scouts--even to
+wreck the Nelson if possible. He decided to, if possible, learn
+something of the fellow before taking him on board the aeroplane.
+
+After a time the strange airship fluttered away to the north and
+then Ned and Pedro descended to the former's room. Sitting at the
+north window, the two could see the lights of the aeroplane dropping
+downward, and they concluded that the aviator was seeking a resting
+place for the night.
+
+"He's going to bed in Inca Valley," Pedro said, watching the
+descending bird. "It is a good place to hide the machine."
+
+The words were spoken in pretty good Spanish, and Ned turned quickly
+and asked:
+
+"You speak Spanish then?"
+
+The question was asked in Spanish, and the Indian's face brightened.
+
+"Yes," he said, "but I never suspected that you knew the language."
+
+"Only a smattering of it," laughed Ned, "but, still, I think you can
+understand what I say to you. As I want you to do most of the
+talking, we may get on very well together."
+
+"What do you want to know?" asked Pedro.
+
+"First, I want you, after we have had our talk, to go out into the
+city and find out, if you can, all about that aeroplane. I want to
+know if it has ever been seen here before, if the aviator comes to
+the city after descending, if he is a stranger here--all about him,
+in fact."
+
+The Indian bowed.
+
+"Then," Ned went on, "I want you to find out whether the machine is
+well guarded. I also want to know what kind of a machine it is, and
+where it came from. If you think it advisable I want you to get
+into conversation with the aviator and see what kind of a chap he
+is."
+
+Another bow from the Indian, whose face expressed pleasure at the
+prospective employment. Ned pondered for a moment, as if not quite
+certain of his ground, and then asked:
+
+"How, well are you acquainted with the country lying between Lima
+and Asuncion?"
+
+"Oh," was the astonished reply, "but that is a long, long
+distance--two, three thousand miles."
+
+"Yes, I know, but have you ever been over the Andes?"
+
+"Oh, yes. I am a guide."
+
+Ned pondered a moment.
+
+"How far east and south?" he asked, then.
+
+"To Lake Titicaca."
+
+"That is on the boundary between Peru and Bolivia?"
+
+"Yes."
+
+"And you know that country--the country around the lake?"
+
+"Very well, indeed."
+
+"It is a long way from Asuncion?"
+
+"It is barely a third of the way. You will see on the map."
+
+"Well," Ned said, after a short silence, "I may as well tell you
+what I want. I want to be directed to a place in the mountains
+where I can securely hide our aeroplane. It must be a hiding place
+absolutely out of sight, especially from the sky. Do you
+understand?"
+
+The Indian nodded, a knowing smile on his dusky face.
+
+"You mean to hide from the other airship?" he asked.
+
+"Yes."
+
+"There are caverns near Lake Titicaca."
+
+"So I understand. Caverns which defy exploration. But, you see, I
+must have a hiding place from which the airship can be brought out
+with speed and returned in the same way."
+
+"To dodge out and in? Yes, I comprehend."
+
+The two dwelt over the maps and plans until; Leroy and Jimmie came
+romping in to report that all was quiet at the machine, and that
+Mike was to remain on guard until midnight, when Jimmie was to
+relieve him. Then Pedro went out in the city to listen to such talk
+of the strange airship as was floating about the streets. He was
+back in a couple of hours with the information that the airship had
+not landed in the city, and that it had never been seen there
+before.
+
+"It seems to me," Ned said after the Indian ceased speaking, "that
+now is our time. We ought to be a long way from Lima before dawn."
+
+"The other fellow'll see us!" Leroy objected.
+
+"We'll have to chance that," Ned replied. "We needn't have any
+lights you know, and the motors make very little noise. Get your
+traps ready, boys!"
+
+It was arranged that Pedro was to remain, under pay, in Lima,
+storing up such information as he could secure against the day of
+the return of the Nelson. Mike was to remain with him, of course,
+as there would be no room on the Nelson for him. The young man when
+told of the plans, objected strenuously to being left, but was
+finally consoled by the promise that the aeroplane would be sent
+back after him when opportunity offered.
+
+It was after midnight when all the arrangements were made and the
+boys passed out of their rooms into the hotel lobby. At that hour
+they thought the driver of the other aeroplane would be likely to be
+sleeping. At the very door of the hotel they came upon Mr. Thomas
+Q. Collins! He strolled up as Ned stepped into the doorway and
+extended his hand. Ned took it, gave it a perfunctory grasp, and
+attempted to paw on.
+
+"If you don't mind," Collins said, with a persuasive mile, "I'll
+walk with you if you are going out to your aeroplane. I've been to
+bed and find that I can't sleep."
+
+"All right," Ned replied, thinking that he would rather have the man
+with him than on his way to report the departure of the Nelson. "We
+are just going to look the ship over--perhaps take a little spin.
+Come along."
+
+"I should like very much to go with you, in case you decide to go
+sailing tonight," Collins said. "Perhaps you may be able to arrange
+it?"
+
+"I'm afraid not tonight," Ned replied, wondering just what this new
+acquaintance was up to. "However," he added, "you may as well come
+along and look over the ship."
+
+Collins seemed glad of even this slight concession on the part of
+the boy, and walked along briskly. Presently, however, he began to
+fall back, talking with Jimmie, who was a few paces behind. Then,
+before very long, the little fellow missed Collins. He had
+disappeared in a dark alley. Ned worried over this when informed of
+the fellow's strange and contradictory conduct. The man might have
+gone to make report to the other aviator! This was not a pleasant
+reflection.
+
+Mike was found sitting in front of the Nelson, talking with a native
+who was trying to learn all about an aeroplane from, a boy who knew
+nothing about it himself! It took only a short time to make ready
+for flight, then the Nelson was up and away, making little noise as
+she cut the air, her great planes flashing in the light of the moon.
+
+"This is pretty poor, I guess!" Leroy exclaimed, glancing over the
+mighty map of sea and plain and mountain. "How fast do you want to
+go?"
+
+"At full speed," Ned replied.
+
+"I should say it would be full speed!" Jimmie said, half covering
+his mouth with his hand, to keep his words from being blown back
+down his throat. "That is," he added, "if you want to make a
+sneak!"
+
+Ned turned away to the north and saw the white planes of the strange
+aeroplane gleaming in the moonlight. She seemed to stand still for
+an instant, and then sped off to the southeast. Ned sighed with
+apprehension, but Leroy laughed.
+
+"Come along, you!" he cried, looking back. "If you want a race,
+come on, and I'll give you the run of your life!"
+
+
+
+
+
+CHAPTER V
+
+JIMMIE TAKES A RUN IN THE AIR
+
+
+The white aeroplane flashed by, going farther to the east, and Ned
+laid a hand on Leroy's arm as he was about to increase speed.
+
+"Don't hurry," he said, almost screaming the words into the boy's
+ear.
+
+"I don't want him to beat me!" the driver called back.
+
+"Let him go," Ned commanded. "Play about the scenery a little
+while, and then we'll go back to Lima."
+
+"Let me catch him!" pleaded Leroy. "Just let me chase around him a
+couple of times. I want to see him make a sneak when he sees the
+Nelson in action!"
+
+"Can you do it?" asked Ned.
+
+"Sure I can do it. Just give me a chance. There isn't a machine in
+the world that can win a race against the Nelson!"
+
+"I'm sure of that," Ned answered, "and I hope that fellow over there
+won't find it out right away. Let him think he can go by us like we
+were tied to a cloud, if he wants to. There will come a time when
+his confidence in his machine will cost him his job!"
+
+Leroy saw that Ned was really in earnest in the expressed wish to
+deceive the aviator of the rival aeroplane, and also saw that there
+was good reason for doing so, so he shut off the motors and started
+to volplane downward.
+
+"No," Ned said, "that's not right. Make him think we're trying to
+catch him. Give him the impression that we want to overhaul him,
+but haven't the speed."
+
+"The Nelson will blush red with shame to be bested by a water wagon
+like that!" Leroy grumbled, but he did as requested.
+
+The white aeroplane's driver appeared to take the bait. He
+loitered, as if waiting for the Nelson to come up, then circled away
+from her in great wide swaths. Once he swept around the Nelson, and
+Leroy almost shed tears of chagrin.
+
+"Just see him!" the boy wailed. "He thinks I've got a dirt cart
+here! He is putting it all over me! I can go two miles to his one,
+and yet I'm taking all his guff! Let me get at him! I'll run him
+down!"
+
+In a short time the stranger, apparently satisfied that he could
+outfly the Nelson, should he desire to do so, moved off to the south
+and soon disappeared in the distance.
+
+"Now what?" asked Leroy, half angrily.
+
+"He'll watch for us," Ned replied, "but he won't find us chasing
+him. Go through some of your flip-flaps and then go back toward
+Lima. I want to say a few words to that Mr. Thomas Q. Collins."
+
+Half mollified at the thought of getting a little speed out of the
+Nelson, Leroy drove straight for the zenith. Up, up, up he went,
+onward toward the stars, shining no brighter for his approach, yet
+luring him on. All the world below was flooded with moonlight and
+starlight. The mountains were dim in spots, where higher peaks
+dominated the light, the Pacific shone in the radiance of the night.
+The blue dome of heaven rounded away like a precious bowl set with
+diamonds.
+
+The roofs of Lima drew closer together, apparently, and the whole
+town looked like a little cluttered point of land. And the
+mountains and the sea stretched away endlessly, and earth took on
+the look of a great rug woven with invisible stripes. Up, up, up,
+until the air became thin and the lungs staggered for breath.
+
+Then the motors were shut off and the ocean and the mountain chains
+seemed to rise up to meet the aeroplane, sailing at the speed of
+the fastest express. Over the water and down until even Jimmie
+clutched Ned's arm and gave forth an exclamation of alarm. Then a
+turn of a lever sent the Nelson skimming over Calleo and back toward
+Lima. Avoiding the vacant space where the Nelson had rested before,
+Leroy, under Ned's directions, landed on the dry sand some distance
+away.
+
+"Of course that other chap will find us when he comes back," Ned
+said, when the boys stood on solid ground again, "but we'll try to
+make him think we're hanging around Peru just for the fun of it."
+
+"Perhaps he won't come back," suggested Leroy. "Then I'll lose my
+chance of showing him what the Nelson can do."
+
+"I have an idea that he'll be back by morning," Ned replied.
+
+In this the boy was right, for the white aeroplane showed in a
+couple of hours, just about dawn, circled around the city, hovered
+for a moment over the Nelson, and then went off to the north again.
+
+"It is a certainty that she is here to butt into our game!" Jimmie
+said, as the white planes disappeared. "She'll start when we start,
+an' stop when we stop, an' there won't be any getting away from her.
+How does she get into the air so quick after we cut loose? That's
+what I'd like to know."
+
+"Some system of signals, undoubtedly," Ned answered. "Now," he
+continued, "we'll cuddle up in our blankets here and sleep as long
+as the natives will let us. Who'll keep awake?"
+
+Each one wanted to be the one to stand guard, but the point was
+decided by the appearance of Mike and Pedro, who had watched the
+maneuvers of the Nelson, had noted her landing place, and hastened
+forward. Thus relieved of the care of the machine, the three boys
+hastened to the hotel and were soon sound asleep.
+
+It was noon when Ned awoke, brought out of a deep slumber by an
+impatient knocking at his door. He was out of bed in an instant
+and, clad only in his pajamas, opened the door and looked out. Mr.
+Thomas Q. Collins stood in the corridor with a look of alarm on his
+face.
+
+"Thought I'd never get you out," he said, stepping, uninvited, into
+the room and taking a chair. "Thought that you ought to know what's
+been going on."
+
+Ned had little confidence in Collins. The fellow's strange conduct
+of the night before naturally made the boy suspicious. After
+requesting a ride in the Nelson, or, at least, the company of the
+Boy Scouts to the place where the machine had been left, he had
+disappeared without a word of explanation.
+
+It seemed to Ned that he had good grounds for the belief that
+Collins had spied around until he had learned that the aeroplane was
+going up, and had then communicated the information to the man on
+the white machine. At least, the strange aviator had shown in the
+air directly after the disappearance of Collins.
+
+But it was no part of Ned's purpose to permit Collins to see that he
+was suspected. It was rather his idea to keep on good terms with
+the fellow and watch him for any evidences of treachery. He
+therefore greeted him cordially and asked:
+
+"Something interesting going on in the city? We did not return
+until nearly dawn, and I've been asleep ever since."
+
+"You haven't heard about the attack on our aeroplane, then?" asked
+Collins, looking Ned over keenly.
+
+The boy tried not to exhibit the least emotion or excitement at the
+disturbing question. Leaning back in the chair he had taken, he
+asked:
+
+"The curiosity of the people got the better of their courtesy, eh?
+I have been afraid of that. Well, I hope the Nelson was not
+seriously injured."
+
+Thomas Q. Collins had the appearance of one who had expected to
+unwrap a great sensation and had failed. His face was a study.
+
+"Well, no," he replied. "The fact is, when the rush was made the
+aeroplane shot up into the air."
+
+"Then one of the boys must have been there," Ned said, calmly,
+although his heart was beating like a drum.
+
+"The little fellow was there, the one you call Jimmie," was the
+reply.
+
+"And he went into the air alone?"
+
+"No; at the last minute a Peruvian Indian who has been hanging about
+the machine ever since you came here went with him."
+
+"Then there is no danger," Ned replied, really feeling relieved at
+the thought that Jimmie was not alone in the aeroplane. "The lad
+will bring the Nelson back in good time. Anyway, he is entitled to
+a little excursion, 'all by his lonely,' as he puts it."
+
+"He can operate the machine?"
+
+"Certainly. He can handle the Nelson easily."
+
+Thomas Q. Collins regarded Ned steadily for a moment, his brusque,
+salesmanship manner all gone, and then asked:
+
+"'Where are you going from here?"
+
+The fellow was showing his hand at last! Or was this just natural
+curiosity? At that moment Ned was more interested in discovering
+something about the attack on the Nelson than in fighting off
+personal and impertinent questions, so he said:
+
+"We haven't made up our minds as to our future course. By the way,
+what was the cause of the attack on the aeroplane?"
+
+"Oh," replied Collins, frowning slightly, "there were a lot of
+people gathered about the ropes, and one of your guards was a little
+coarse in protecting your property, and there was a blow struck,
+then the mob rushed the roped-in enclosure. I think there was no
+one seriously injured."
+
+"I wonder if the other aviator is also having trouble with his
+machine?" asked Ned, anxious to know what Collins would say about
+the white aeroplane.
+
+"I don't know about that," Collins replied. "In fact, the other
+fellow went off to the south soon after the departure of the
+Nelson."
+
+"Chased Jimmie up, eh?"
+
+"Well, anxious for a race, it seemed to me."
+
+"Has the Nelson returned?" asked Ned, then.
+
+Collins shook his head.
+
+"If you'll excuse me, then," Ned said, presently. "I'll dress and
+take breakfast and go down to see what's doing."
+
+"Your breakfast will be luncheon, I guess," laughed Collins. "I was
+on my way to the dining room when I thought of you. If you don't
+mind I'll wait for you in the lobby. These natives are not very
+good table companions. I'm sick for the sight of my own countrymen,
+anyway, and I can't tell you how glad I am to see you here."
+
+Collins went out and closed the door and Ned set about his toilet.
+He did not know what to make of the alleged steam pump salesman. At
+times he appeared to be perfectly frank and honest, then there would
+come to his eyes a look of half-concealed cunning and greed which
+put the boy on his guard.
+
+However, Ned thought, the correct way to fathom the fellow's
+intentions would be to remain in his company as much as possible.
+So the boy bathed and dressed and went down to Collins in the lobby
+with a cheerful face.
+
+During the meal Collins talked incessantly of the country and his
+prospects in South America. Ned listened, saying little, even in
+the short spaces of silence. He was waiting for the fellow to
+strike some chord which tuned with his actions of the night before.
+At last it came.
+
+"I'm thinking of going over to Asuncion," he said, when the meal was
+nearly over. "There are mines over that way, and I may stand a
+chance of selling a pump. Rotten luck in Peru, and I can't afford
+to spend all this expense money and not sell a thing. I hear that
+there are a few Americans over in Paraguay," he added, tentatively,
+smiling over at Ned.
+
+"I know very little about the country," Ned said, coolly, fearful
+that Collins would drop that line of conversation, "and I never
+heard that foreigners of any sort were made welcome in Paraguay. I
+don't think we'll go out of our way any to visit that hot little
+republic."
+
+Collins looked disappointed. Ned could see that. In a moment he
+tried again to bring the subject out, but Ned seemed entirely
+indifferent.
+
+When the two left the hotel and walked in the direction of the sand
+lot where the Nelson had been left, the boy was fully satisfied that
+Collins was in league with his enemies. For all he knew, the fellow
+might be the very man who was trying to get Lyman's concession away
+from him. This might be the man who was bribing the crooked
+military chief to make it impossible for the cattle man to carry out
+his contract.
+
+"What time did the Nelson leave?" Ned asked, as they drew near a
+little group of natives standing on the sand lot.
+
+"Not far from nine," was the reply.
+
+"I didn't think Jimmie would be out that early," laughed Ned. "He
+is a little sleepy head, ordinarily."
+
+Pushing their way into the center of the little crowd, Ned and
+Collins found Leroy and Mike Dougherty engaged in a heated debate
+with a police officer who was threatening arrest. Ned stepped back
+so as not to attract the attention of the boys, and kept his eyes
+fixed on Collins. In a moment he saw that gentleman give an
+impatient gesture which seemed to urge the officer on.
+
+Ned thought fast for a moment. He was considering whether or not he
+had been brought there for the purpose of getting into a row in defense
+of his chums and being arrested with them. He was heartily glad that
+the Nelson was out of the way, although he would have been better
+pleased had he been safe aboard of her.
+
+"These Peruvian officers are too fresh!" Collins said, in a moment.
+"What do you mean by molesting these boys?" he added, in Spanish,
+turning to the officer.
+
+"They are charged with assault," the latter replied.
+
+"By whom?" asked Ned, also speaking in Spanish.
+
+"They struck half a dozen citizens," was the indefinite reply. "We
+must take them to jail."
+
+"I'll give you a bump in the eye if you come near me!" Leroy put in,
+as he searched the sky eagerly for some sign of the Nelson.
+
+"That wouldn't help matters any," Ned said, speaking in English.
+"Go along with the officer, and I'll pay your fine."
+
+Collins looked annoyed at this cautious advice. He came nearer to
+Ned and whispered:
+
+"The courts are slow and uncertain here. It may be weeks before the
+boys will be restored to liberty if they are locked up. If we could
+get them away into the mountains until the Nelson returns that would
+end the whole affair."
+
+"And so you want to get me mixed up in it, too!" thought Ned, as the
+officer glared at him. "You want to get me on a charge of resisting
+arrest! When we get out of here, Mr. Thomas Q. Collins, I'll see
+that you get what's coming to you!"
+
+If Collins could have known what was passing in Ned's mind, could
+have understood how suspicious the boy was of him, he would not have
+urged the lads, in English, to cut and run. By doing so he merely
+confirmed Ned's unfavorable opinion of him. From that moment Ned
+knew him for what he was, and resolved to get him out of the way in
+some manner.
+
+Leroy and Mike paid little attention to what Collins said, as a
+shake of the head from Ned gave them to understand what was passing
+in his mind. In a moment Ned stepped to the side of the policeman.
+
+"You are all right, officer," he said. "You are only doing your
+duty. The boys will go with you, and I'll pay their fines."
+
+But, as Ned discovered, it is easier to get into jail in Peru than
+it is to get out.
+
+
+
+
+CHAPTER VI
+
+NED IS GUILTY OF LARCENY
+
+
+Night came on and no Nelson showed in the sky. Ned wandered
+restlessly about the rather handsome city, anxious for the aeroplane
+as well as for the boys who were in the city prison. Collins was
+always with him, at first, expressing sympathy and suggesting plans
+for getting the prisoners out on bail. The complainant in the case,
+it was claimed by the officers, was too badly injured to appear in
+court.
+
+Ned grew sick of the constant talking of the fellow at last, and
+went to his room, saying that he was due for a little sleep. But
+the boy, as may well be imagined, did not sleep. Instead, he sat by
+his window watching the sky.
+
+Where had Jimmie gone with the machine? This question was always in
+his mind. Had he met with an accident and was he lying, crushed
+from a long fall, in some mountain canyon? Had the pursuing
+aeroplane overtaken him and destroyed or captured the Nelson?
+
+It was not like the little fellow to disappear so utterly. Even
+supposing he was afraid to return to Lima, he ought to understand
+how anxious his friends would be and signal them from the upper air.
+Surely, Ned reasoned, this would be safe, for the hostile machine
+could not approach the Nelson in speed, and, after giving a
+reassuring signal, the boy could disappear in the mountains again.
+
+It was dark now in the room where Ned was, and he sat looking out at
+the sky in the hope of seeing the welcome lights of the aeroplane.
+Presently, he saw a flicker of light off to the east. It increased
+in size rapidly, and Ned knew that it was an airship he saw
+approaching at wonderful speed, but he had no means of knowing
+whether it was Jimmie on the Nelson or the hostile aviator.
+
+If it was Jimmie, he thought, there would be a signal directly. He
+waited eagerly, but no signal showed. Presently the airship drifted
+off to the north, and Ned saw the glint of moonlight on white
+planes. It was the hostile ship, sure enough, but why had she
+abandoned pursuit of the Nelson?
+
+Ned resolved to secure a closer view of the airship, but the next
+question was how to avoid Collins, who was at that moment pacing to
+and fro in front of the hotel. The alleged salesman would be apt to
+accost him as soon as he appeared and insist on going with him.
+
+He had had enough of Collins. He had no doubt that the fellow was
+in the conspiracy against him. It seemed reasonable that he had
+been warned by wire of the approach of the Boy Scouts, and had
+hastened to Lima to intercept them. Ned thought over the situation
+deliberately, and then a daring smile came to his face.
+
+"I wonder if I can?"
+
+He chuckled as he asked himself the question.
+
+"I wonder if I can?"
+
+He paced his room for a moment, and then continued.
+
+"If he goes with me, there will be less suspicion, provided I am
+right in my estimate of the fellow. We may be even left alone with
+the aeroplane! Ah, that would be too good to come true!"
+
+The boy watched the sky to the east from the roof as well as from
+his window, but there were no signs of the aeroplane which Jimmie
+had taken away.
+
+"The little rascal knows what he is doing!" Ned told himself, "but I
+wish he would let me know, too! I reckon I'll take a chance on the
+plan. I'll try anything once, as the Bowery boys say."
+
+Having settled the vexed question in his own mind, Ned went
+whistling down the broad stairway and came out in the lobby. Just
+as he had figured, Collins sat where he could keep an eye on the
+front entrance. When Ned appeared the fellow arose and stepped over
+to him.
+
+"There is nothing new, I'm afraid," Collins said. "I've just been
+over to the police station, and nothing can be done tonight."
+
+Ned thought that Collins must have made pretty good time to get over
+to the police station and back during the short space of time he had
+been out of sight, but he did not say so.
+
+"Anything new about the aeroplane?" asked Ned. "I saw the white one
+come back."
+
+"Perhaps she can give us the information we want about your ship,
+or, perhaps the aviator can," he added with a laugh.
+
+"Why not go and see?" asked Ned, his heart bounding with hope and
+excitement as he noted how eagerly Collins took the bait. "Can we
+get a motor-car here? The machine must be quite a distance away."
+
+"It does look that way," Collins replied, with a yawn, "and we may
+as well take a car, if we can find one. I hope you don't mind my
+going with you."
+
+"Why, I wouldn't go alone!" Ned replied, speaking with perfect
+truth, as Collins discovered later on. "You don't know how glad I
+am to find you up and ready for a little adventure!"
+
+Collins, in turn, told how pleased he was to be of service, and the
+two found a motor-car and started off, taking a road which ran along
+a level strip of land which lay between the sand and the mountains.
+They had proceeded a couple of miles when a motor-car appeared in
+sight just ahead of them, traveling toward the city.
+
+Collins arose in his seat and waved his hand frantically.
+
+"I believe that's Sherman!" he cried. "Sherman's here for a rival
+steam pump firm, but I'll be good to him, especially as there is
+nothing doing in the way of trade. Hey, there, Sherm!" he shouted
+as the two cars drew nearer. "Pull up and give an account of
+yourself!"
+
+Sherman was a dark-faced, black-haired, bewhiskered fellow of
+perhaps forty. He was dressed in a dark business suit and wore
+glasses. The two men talked shop for a moment, and then Collins
+asked:
+
+"Where have you been?"
+
+"Just out for a ride," was the reply.
+
+"You saw the airship come down?"
+
+"Of come, but I'm not interested in airships."
+
+"Then you haven't been out there?"
+
+"Hardly. It doesn't interest me--this aviation craze."
+
+"Then you don't know whether the aviator is out there or not?"
+continued Collins.
+
+"Why, yes, I do know about that," Sherman replied. "I heard this
+driver of mine talking Spanish with a shoofer we met, and learned
+from the mix-up in tongues that the aviator has gone to the city,
+leaving a couple of natives in charge of the machine."
+
+Ned's heart bounded so fiercely that he feared that Collins would
+hear its quick beats! The aviator was not there. Only two
+Peruvians, timid chaps at best! Mr. Thomas Q. Collins might receive
+his reward for his treachery sooner than he imagined, the boy
+thought!
+
+"Well, so long!" Collins cried. "We'll see you in the city
+tonight."
+
+The cars parted, each going its separate way, and Ned and Collins
+were soon within sight of the white aeroplane, which lay in a valley
+a short distance from the road. The spot where it lay was well
+irrigated, and fruits and vegetables were growing all around the
+rope which had been strung about the machine. The aviator had
+evidently paid a good price for the privilege of landing there.
+
+A short distance away from the site of the machine was a small
+house, a tiny affair, with plenty of porches and a flat roof. As
+the two men left the car and advanced toward the machine a man left
+the porch and walked in their direction.
+
+"Probably the farmer," Collins said. "We may have to pay for the
+privilege of looking over the machine."
+
+Much to the amazement of the boy, the man who approached from the
+porch spoke to the two in English.
+
+"What do you want?" he asked.
+
+Ned waited for Collins to make a reply. If Collins really was in
+the conspiracy against Lyman, he would probably show his hand within
+the next few minutes. Just as Ned anticipated Collins gave the
+other a sly signal before he opened his mouth. Ned was not supposed
+to see this evidence of a common understanding, but his watchful
+eyes caught not only that but the answering sign of the other.
+
+"We came up to look over the machine," Collins said.
+
+"Well, you keep away from it," the other replied, fixing his eyes
+keenly on the face of the boy.
+
+"This lad," Collins said, then, motioning toward Ned, "knows
+something about an aeroplane, and wants to inspect this one."
+
+A sly wink followed the remark. It was getting rather cheap to Ned.
+The collusion between the two was so evident that their attempts to
+conceal it appeared very slazy.
+
+"Yes," Ned put in, "I'd like to look the machine over."
+
+"You came in that other aeroplane?" was asked.
+
+Ned nodded, and Collins broke in:
+
+"He's an expert, but he has no machine just at present. A member of
+his party took his machine away this morning," he added, with a
+chuckle.
+
+"So Rowan said," the alleged farmer replied.
+
+"Rowan?" repeated Ned. "Is that the name of the aviator who runs
+this machine?"
+
+"Yes; he is a New York man. Do you know him?"
+
+Ned replied that he had heard of him, knew him to be a splendid
+operator, but had never met him.
+
+After some further talk Ned and Collins were given permission to
+look at the machine, which was called the Vixen. Collins expressed
+his thanks in elaborate language, but Ned went straight to the
+Vixen, which was then guarded by a Peruvian Indian. He was weary of
+the cheap pretense of the other.
+
+"This is a peach of a machine," the alleged farmer explained,
+following Ned as he walked about the great planes. "See here! No
+cranking at all! You just get into the seat, which will carry two
+nicely, and push this button. That releases a spring which whirls
+the propellers until the spark is made, then off you go."
+
+Ned admired the arrangement fully, as he was expected to do. The
+Nelson was fitted out in the same way, but he did not say so.
+Presently the Indian left the circle created by the rope and, going
+into the shelter of the porch, left Collins and Ned with the alleged
+farmer, who announced that his name was Yerkes.
+
+Ned thought this action on the part of the Indian was in obedience
+to a signal from Collins, but could not be too sure of it. Then
+Collins and Yerkes trailed about after Ned as he wandered around the
+airship. The boy saw the former remove certain bits of wood which
+blocked the wheels of the Vixen, also he saw Yerkes, testing the
+gasoline gauge and looking the carburetor over carefully.
+
+"It is all right," the boy thought. "Two hearts with but a single
+thought, two souls that beat as one--or the reverse anyway, they are
+thinking of giving me a ride in this old ice wagon! Pretty soon
+they'll be asking me to get up on the seat and see how easy it is.
+Then one of them will slip this harness about me--the harness
+provided for timid riders--and I'll be off in the air--a prisoner!"
+
+Collins and Yerkes tinkered about the aeroplane for some moments,
+while Ned seemed to be studying the machine. The boy was anxious
+for the decisive moment to come.
+
+Finally Yerkes, went back to the porch and stood there in
+conversation with the Indian for a number of minutes.
+
+When he returned Collins stepped forward toward the seat.
+
+Knowing that the time for action had come, Ned sprang into the
+driver's seat. Collins looked vexed at the movement, but Ned
+laughed down at him.
+
+"I won't hurt your old machine," the boy said. "Get up here, so we
+can see how it rides."
+
+Collins obeyed, first giving Yerkes a significant look which was not
+lost on the watchful boy.
+
+The harness for the visitor's seat was a peculiar one, as Ned had
+noted with considerable satisfaction. There were leather cuffs for
+the wrists and a broad leg band which prevented the guest leaving
+his seat. The cuffs held the hands close together in the lap, the
+idea being to prevent a timid person from grasping the arm of the
+driver in a moment of terror.
+
+"Move on over!" Collins called, as he stepped up, "and I'll see if I
+can take you out of the valley without breaking your neck. Don't
+say a word to Yerkes about his race with the Nelson," he added, in a
+whisper. "He got beaten, and doesn't like to talk about it."
+
+Ned noticed but remained where he was, so Collins reluctantly took
+the other seat. As he did so Yerkes stepped forward, and the Indian
+stationed himself at the back of the machine, where he could give it
+a push down the incline which lay before it, and against which the
+wheels had been blocked.
+
+As soon as Collins was fairly in the seat, Ned gave the harness a
+quick snap, and the click of metal told him that the cuffs had
+closed about Collins' wrists, that the broad strap which held him
+down was in position. Then he pushed the button and the spark
+caught. The Vixen moved down the incline.
+
+Collins tried to lift his hands, but was unable to do so, so he
+lifted his voice instead! Yerkes, in the whirr of the machine,
+doubtless mistook the voice for that of the boy, for he paid no
+attention to it.
+
+"Help! Help!" roared Collins. "Stop the machine! He's got me tied
+down! Stop it, you fool! Stop it!"
+
+Yerkes and the Indian looked stolidly on with grins on their faces,
+and Ned stuck an elbow into Collins' ribs.
+
+"Keep still," he said, "or I'll have to put you out of the speech
+habit. I've got you just where you expected to get me, and you
+ought not to kick about the accommodations."
+
+"Yerkes!" yelled Collins. "Why don't you stop the machine? Catch
+hold of the propellers and yank them off! Put a bullet through this
+young fiend! Anything to stop the crazy thing. I tell you he's got
+me tied in!"
+
+Then Yerkes, recognizing the voice, sprang toward the propellers.
+He made a brisk spring, but was too late. The blades were just
+about an inch out of his reach. Foiled in this attempt, he drew a
+revolver and began firing foolish shots at the machine, none of
+which came near the mark.
+
+In a moment the Vixen was under full speed, the ground dropped away,
+and the last Ned saw of Yerkes and the Indian they were performing a
+dance of rage on the growing vegetables below. Straight to the
+south the machine flew, the motors popping like mad.
+
+The boy saw little crowds in the lighted streets below, looking and
+pointing up at the aeroplane, and then the city streets faded away
+into a dull mat, and there were only the silent peaks, the sea, and
+the deep, dim valleys.
+
+Then Ned turned to his prisoner, who had by this time given over the
+useless struggle against the harness. Collins' eyes were fixed on
+the moonlit Pacific, away off to the west, and the boy's eyes
+followed those of his captive.
+
+A steamer was creeping into the shallow harbor at Calleo, and the
+dark spot on the sand showed that a crowd was there to greet her.
+The Vixen was too far away for Ned to see the surf boats getting
+ready to take off the passengers and freight, but he knew that they
+were there.
+
+It was now eleven o'clock, and the moon was well up in the sky. The
+ribs of the Andes lay like silver in its light. Strain his eyes as
+he might, there was no indication of the Nelson.
+
+"Fine view!" Ned said, presently, giving Collins a nudge in the ribs
+with his elbow. "How do you like it?"
+
+Thomas Q. Collins was near bursting with rage. He hitched about in
+his seat, but to no purpose.
+
+"What does this mean?" he finally found words to say, screaming at
+the top of his voice, for the Vixen was now making good speed.
+
+"I preferred to be the host rather than the guest," the boy said,
+with a shrug of the shoulders.
+
+"I don't know what you mean by that," Collins replied.
+
+"You meant to capture me tonight?" asked Ned.
+
+"Nothing of the kind!" roared Collins.
+
+"You got Leroy and Mike in jail, and you thought you'd burst up this
+relief expedition by putting me out of the way," Ned went on. "Now,
+we'll see who'll be put out of the way."
+
+"What are you here for?" asked Collins.
+
+"You know very well," replied Ned. "But it is too much exertion to
+talk at this speed. Wait until we land and I'll tell you all about
+your intentions! Understand? All about your intentions."
+
+"Much you know about them," shrieked Collins.
+
+Ned made no reply to this, for, away off to the southeast, he caught
+sight of the dipping lights of an airship which might or might not
+be the Nelson.
+
+
+
+
+CHAPTER VII
+
+THE BLACK BEAR IN TROUBLE
+
+
+One still night on the Amazon Jack Bosworth got out a map and turned
+a flashlight on it. Frank and Harry stood looking over his
+shoulder.
+
+"Right here," Jack said, presently, "is where we leave the main
+stream of the Amazon and take to the Madeira."
+
+"How do you know that stream is the Madeira?" asked Frank. "We have
+passed so many large tributaries that I'm all mixed up."
+
+"And why not try some other stream?" Harry questioned. "I've heard
+that the Madeira is full of falls and rapids."
+
+"Anyway," Jack insisted, "it takes us away up into the Andes, almost
+to Lake Titicaca, and that's all any stream will do. As for the
+falls and rapids, do you expect any stream to creep down from that
+great plateau without jumping off occasionally?"
+
+"All right," Frank cut in. "Go your own way to destruction! But
+how do you know that rippling sheet of water off there," swinging an
+arm to the south, "is the Madeira river? It looks like a lake to
+me."
+
+"I found out while you were asleep this morning," Jack replied. "A
+chap came along in a launch and I asked him all about it. He said
+he had just come from the Andes, and advised me to turn back."
+
+"Kind-hearted little fellow, eh?" laughed Harry.
+
+"He wasn't very little," answered Jack. "He was six feet two, and
+was coming out with a finger off and a cut across a cheek bone which
+will last him for a spell, I guess. He cut his finger off because a
+poisoned arrow struck it."
+
+"Cannibals?" asked Harry, with a laugh.
+
+"The same," replied Jack. "Said they chased him for miles."
+
+"We'll curb their appetites with lead," Harry observed.
+
+"If we see them first," added Jack.
+
+So the Black Bear was turned into the Madeira river, which is
+something like seven hundred miles long, and drains the wooded
+country where the black sheep of the land of Brazil live. Away up
+in the hills it is fed by the Beni river, which has its source in
+the mountains east of Lake Titicaca.
+
+ More than once the boys were obliged to haul their motor boat out
+on a rocky "bench," take it to pieces, carry it and most of the
+stock around rapids, and then put it together and load up again.
+Still, they made good time, and on the evening of the third day
+found themselves at the junction with the Beni river.
+
+They were now in a wild and dangerous country. The forests swarmed
+with wild game, the thickets were full of serpents, and the trees
+were often crowded with monkeys. For two days they had seen no
+natives. This was suspicious as it was certain that they had
+penetrated to the home of the cannibal tribes so greatly dreaded by
+hunters and explorers.
+
+It was on the evening of the 21st of August that Jack sent the Black
+Bear into a little creek, shut off the power, and turned to put up
+the panels. It was not very warm, but the atmosphere was sticky and
+heavy with the breath of the woods.
+
+"We'll smother in there tonight," Frank said, observing the actions
+of the other. "Why not leave some of 'em out?"
+
+"If you want a poisoned arrow nestling in your ribs you can sleep
+outside," Jack answered. "For my part, I want to wake up in this
+good old world in the morning."
+
+"I don't think there's any danger yet," Frank said.
+
+But the panels were put up and supper prepared. By this time the
+lads had become accustomed to preparing their own meals, as well as
+providing the fish from the river, and the repast was soon over.
+Then Jack lay back and gazed through the one glass panel of the top
+of the Black Bear.
+
+It was a dark, lowering night. The wind is usually from the east in
+that part of Brazil. Blowing over the Atlantic it gathers up
+moisture to dump on the eastern slope of the Andes. The summits
+drain the clouds and makes Peru a dry country. It was murky now,
+and the clouds hung low.
+
+"What do you see up there, Jack?" asked Frank. "Trying to study
+astronomy, with not a star in sight?"
+
+"There you are wrong," Jack replied. "There is at least one star in
+sight."
+
+"With that mass of clouds drifting over the sky?" laughed Harry. "I
+reckon you must be seeing things not present to the senses!"
+
+"Come and look, then," Jack invited. "Look straight up, and you'll
+see a star."
+
+Frank placed himself under the glass panel and looked up.
+
+"Well?" Jack demanded, in a tone of triumph.
+
+"It's something," Frank exclaimed, "but I don't believe it is a
+star."
+
+"It may be a reflector at the top of the Flatiron building," grinned
+Jack. "What is it, if it isn't a star?"
+
+"Look yourself!" cried Frank.
+
+The boys were all looking now. They saw the light which Jack had
+mistaken for a star flashing to and fro under the clouds like a
+firefly. It rushed earthward with amazing speed for an instant,
+then spiraled upward again. Once it came directly over the Black
+Bear, and seemed about to drop down.
+
+Jack threw a couple of panels open, and then the whirr of motors
+reached their ears. Frank sprang outside and turned a flashlight
+upward.
+
+"There's your star!" he shouted to Jack.
+
+"Quick!" Harry cried. "Wigwag with that light. It is the Nelson!
+They may be able to see us!"
+
+"Yell, every soul of you!" directed Frank. "Yell! She is going
+away!"
+
+The boys waved their lights frantically and shouted at the top of
+their voices, but the light in the sky crept away to the west and
+soon disappeared, evidently passing above the clouds which lay like
+a black blanket over the Brazilian forests.
+
+"Great heavens!" Jack sighed. "If we could only have made them
+hear! I'll bet they've been to Paraguay and released Lyman. Now
+they're going back home! Fine show we now stand of having any fun
+with them!"
+
+"They went west," Harry corrected. "That isn't the way home!"
+
+"I'd like to know just what success they have had," Jack went on.
+"Say," he continued, "can't we do something to attract their
+attention? Why not set fire to some big dry tree and let her blaze
+up?"
+
+"I just can't have it this way!" Harry said. "I can't stand it to
+have them come so close to us and then go away without knowing we
+are here. We've got to bring them down in some way."
+
+"But they've gone!" Frank declared, gravely.
+
+"If we make a big blaze," Jack hastened to say, "the reflection on
+the clouds will attract their attention, and they'll come back.
+They won't be able to see the fire itself, of course, but they'll
+see the reflection, and that will bring them down to investigate.
+Then we'll fire our revolvers and wigwag with blazing sticks until
+they see who we are."
+
+"It may not be the Nelson," Harry suggested.
+
+"I don't believe there's any other aeroplane sailing about the roof
+of the world," Frank replied. "Of course it is the Nelson!"
+
+"Perhaps the Nelson was followed," Harry went on. "I've heard of
+such things. The chap in that machine may be looking for Ned.
+Anyway," he added, "it won't do any harm to let the aviator, whoever
+he is, know that we are here. Come on, let's go ashore and build a
+big fire."
+
+"I certainly would give a year's growth to know whether that is the
+Nelson," Harry said, as the boys sought the shore and began
+gathering dry wood, which, it may be well to add, was not easy to
+find, as there had been quite a shower during the day. "For all we
+know," he continued, "there may be another aeroplane here. If the
+people who are trying for the Lyman concession are as active here as
+they seem to have been in Paraguay, they may have half a dozen
+airships out after the Nelson."
+
+Finally a quantity of wood which was fairly dry was secured, and
+Jack bundled it up against a dead tree which seemed to run straight
+up into the sky until it touched the clouds. But when the boys came
+to apply matches they discovered that the wood was not dry enough to
+be ignited in that way.
+
+"I'll get a gallon of gasoline and pour over it," Frank explained.
+"Then we can run like blazes when we touch her off. What?"
+
+The gasoline was brought, and the blaze started with a mighty
+concussion of the air. A portion of the highly inflammable fluid
+had entered a great crevice in the dead tree, with the result that
+there was an explosion which resounded through the forests for
+miles. Then the flames mounted the tree, which was soon blazing
+like a great torch.
+
+"I guess that will attract their attention!" Jack said, shielding
+his face from the intense heat.
+
+"Yes," Frank replied, "and I'm afraid it will attract the attention
+of others, too. You know we were told to sneak through this country
+like little mice!"
+
+"It is too late now!" Jack said, a shadow of anxiety coming over his
+face. "We are in for it, I guess. What shall we do?"
+
+Above the crackling of the flames, above the drawing and sighing of
+the wind, there now came a strange sound which seemed to proceed
+from the fire-tinted clouds above. Now and then branches of the
+nearby trees stirred mysteriously, and at times a wild shriek rose
+above the monotonous chattering.
+
+"Monkeys!" cried Jack. "They've come out to help us bring the
+airship to earth. Good little beasts!"
+
+"Don't be in too much of a hurry to give the little devils a
+certificate of good character!" Harry answered. "They may make
+trouble for us."
+
+After a time the foolish, wrinkled faces of the monkeys were seen
+peering from trees. Then, above the din they made, above the
+crackling of the fire, constantly mounting higher, came a scream
+almost like that of a child.
+
+"That's a jaguar!" Harry declared, "a South American tiger, and we'd
+better be getting toward the boat."
+
+"The animals won't come near the fire," Frank said. "We may as well
+remain here and see the menagerie."
+
+Directly it seemed to the excited lads that all the wild animals in
+South America were assembled about their signal. Harry declared
+that he heard the call of the red wolf, the scream of the tiger cat,
+the wail of the puma, the vicious snarling of the wild dog.
+
+While the boys listened to the chorus their efforts to attract the
+attention of the aeroplane had produced, there came into the discord
+another sound--the hissing of a monster serpent. Heretofore the
+boys had little to do with Brazilian forms of animal life, for they
+had kept near the middle of the main stream of the Amazon, and also
+about in the center of the Madeira and the much smaller Beni, which
+was only a creek when compared with the other rivers.
+
+Occasionally they had seen a monster cayman nosing against the
+current, and at times their progress had been retarded by turtles,
+but they had never before seen anything like this. Their fire had
+certainly brought out a combination in nature which would have been
+decidedly interesting if it hadn't been so threatening.
+
+"Me for the boat!" Jack said, with a shiver, as the serpent launched
+his head and a third of his body from the tree and swept about in
+widening circles. "I never could endure snakes!"
+
+"I'm going to take a shot at it," Frank said. "I'd like to see him
+take a tumble into the fire."
+
+"Better let him alone," Harry advised.
+
+Frank was about to fire when Jack caught his arm and held up his
+hand in a listening attitude.
+
+"What is it?" Frank asked.
+
+"Human voices!" was the quick reply.
+
+"Inhuman voices, I should say," Harry observed, after a second of
+silence.
+
+A chant unlike anything the boys had ever heard before undulated
+through the forest. It rose and fell with the gusts of wind, and
+always nearer to the fire.
+
+"This is a new one on me!" Jack cried. "It is also another reason
+for getting to the boat! Come on, fellows!"
+
+"I'm not going to run until I find out what that is," insisted
+Frank. "I'm going to write a newspaper story about this menagerie!"
+
+"If you want your story published in this world," Jack cried, "you'd
+better get under cover, for that's the chant of the head hunters!"
+
+"Wow!" cried Frank, and he beat both his chums to the boat.
+
+ "I guess we've started something!" Jack said, as he busied himself
+putting up the few panels which had been removed when they went
+ashore. "Now, some one push that button, and I'll get the Black
+Bear out of this creek. A good old scout like the Black Bear has no
+business associating with the wild animals on shore."
+
+"Right you are!" shouted Harry, and the propellers began moving.
+Still, the boat made no progress to the rear, the reverse being on.
+
+"What's doing?" demanded Jack. "You'd better hurry, for the head
+hunters are coming right along. See that big chief over there?
+He's got a club that would level the Singer building at a blow!"
+
+"I can't make her back," Harry complained. "There's something the
+matter below her in the stream. It was all clear when we came in."
+
+In an instant all was intense excitement on board the motor boat.
+There was only one way in which the savages could reach them, and
+that was to block their passage out and starve them to death! Had
+this system been resorted to? Had the cunning savages obstructed
+the little stream while the lads were busy building their fire and
+observing their menagerie, as they called it?
+
+These questions were in the minds of all as efforts to back the
+Black Bear were redoubled. Finally Jack opened a panel at the rear
+and looked out, a thing he should have done at first.
+
+What he saw was a large log blocking the channel. The propellers
+were pounding against it, and one of them was broken.
+
+"I guess the little brown men have got us good and plenty," he said,
+slowly, as he reached forward and shut off the power. "While we
+were playing about the blaze they plugged the river."
+
+"They can't get in here, anyway!" Frank consoled.
+
+"No; they'll wait for us to get good and hungry and go out!" Jack
+replied.
+
+The situation was a serious one. The head hunters now appeared in
+the open space about the blazing tree and shook their spears and
+their clubs at the boat. Now and then an arrow with a poisoned tip
+struck the side of the Black Bear.
+
+"They'll never leave until they get us!" Jack said, presently, "and
+so we may as well get a few of them. Get your guns, boys."
+
+"Just you wait, old hard luck prophet," Frank exclaimed. "Look up
+through the glass panel above your head and tell me what you see."
+
+"Well," Jack replied, "it looks like we had established
+communication with the Nelson at last. And also with the Greatest
+Show on Earth!" he added, as a mighty roar went up from the shore.
+
+The other boys crowded the panel and looked out. The clouds above
+were red with the reflection of the blazing tree, yet against the
+mass a different light blazed out. This light moved about, from
+north to south and back again, as if searching out the reason for
+the strange happenings below.
+
+The popping of her motors could be plainly heard, and so it was
+probable that those on the airship could hear the wild animal
+concert which was going on in the woods. Harry pushed a panel aside
+and fired three quick shots. The aeroplane wavered above the river
+a moment and then drifted away.
+
+"They must know there's somebody down here in trouble!" said Harry.
+"Why don't they throw down dynamite? That would give the savages
+all the heads they wanted for a time, I guess."
+
+The boys fired again and again, flashed their lights in wigwag
+signals, but the aeroplane did not come nearer. Instead it whirled
+swiftly about in a circle for a moment and then shot out of sight
+beyond the clouds.
+
+And every moment the circle of savage faces gathered closer about
+the Black Bear, effectively blocked in the narrow stream.
+
+
+
+
+CHAPTER VIII
+
+THE VIXEN TAKES A TUMBLE
+
+
+While Ned, from the driver's seat on the aeroplane he had so
+cleverly taken from the enemy, watched the distant light flashing
+over the mountains, the bulk of an airship came into view. While
+the boy was cheering himself with the hope that he would soon be in
+touch with Jimmie, however, the light disappeared, and the dark body
+of the machine was no longer visible.
+
+"There's been an accident!" Collins muttered maliciously, in Ned's
+ear. "That little chap can't run an aeroplane!"
+
+"What is there over in that direction?" Ned asked, without replying
+to the other's suggestion of evil. "Can one land there?"
+
+"Not in the night," was the sullen reply. "Unless you want to
+commit suicide and murder me in the bargain, you'd better keep in
+the air."
+
+"What's over there?" repeated Ned.
+
+"Mountains," was the surly reply.
+
+Ned pointed to a dark stretch below.
+
+"That must be a valley," he said. "Anyway," he went on, "I'm going
+down, and if we come to a point where it is jump or go down with the
+machine, I'll cut you loose, so you'll have the same chance for your
+worthless life that I do. That's more than you would do for me
+under the circumstances!"
+
+Ned guided the Vixen to, as near as he could make out, the location
+of the other airship at the time of her disappearance and dropped
+down. As he swept toward the earth the peaks of the Andes rose
+above him.
+
+Down, down, down he dropped, looking out keenly for trees and jagged
+rocks. At last he saw a level stretch of land just below. The
+rains had carried sand and ruble down from the mountains and filled
+a valley perhaps three hundred feet in diameter with the wash of the
+slopes. This formed what seemed to be a pretty good landing spot,
+and Ned managed to bring the rubber-tired wheels of the airship down
+without mishap.
+
+Then, rolling swiftly under the impetus given by the now shut-off
+motors, the wheels carried the bulk of the ship along for some
+distance and dropped. Ned felt himself falling.
+
+Thomas Q. Collins cried out in fright, and tried to kick himself
+free from the harness, but the leather straps held. When the drop
+ended there was, a jar and a crash, and the planes lay in a confused
+heap in the bottom of a depression well stocked as to floor and
+sides with jagged rocks.
+
+In descending, the dragging propellers had loosened some of the
+rocks, and they, rolling down the declivities after the machine, had
+fallen upon and crushed the planes. Several great boulders thunked
+near Ned's head, and Collins set up a great howl as a small stone
+landed on the back of his neck.
+
+Although the stars were shining brightly and the moon was abroad, it
+was quite dark down in the hole into which the Vixen had fallen.
+Ned could see slanting walls on all sides, and glimpse, above, the
+slope of the deceiving level which had first caught the wheels, but
+that was about all.
+
+Finding himself uninjured, his first move was to get out his
+searchlight and make an inspection of Thomas Q. Collins, who was
+roaring like a wounded bull.
+
+"Are you hurt?" the boy asked.
+
+"Hurt!" howled the captive. "My head is broken, and my arms are
+smashed! What do you mean by tying me up and then wrecking the
+machine?"
+
+Ned searched the fellow's clothing, removed a revolver and a dagger,
+and then snapped off the harness which still held him to the seat.
+Collins stretched himself and lunged at the boy.
+
+"Keep away!" warned Ned.
+
+"I'll show you that no Bowery kid can double-cross me!" Collins
+screamed, paying no attention to the automatic in Ned's hand. "I'll
+show you!"
+
+The next moment Ned would have fired, with the intention of wounding
+the enraged fellow, but a boulder intervened, and Collins went down,
+striking his head on a rock. When the boy bent over he found him to
+be unconscious.
+
+Bringing the leather straps of the harness into use again, Ned bound
+the man's hands behind his back, so as to prevent a second attack,
+and set out to look for water. He had not long to look, for a tiny
+spring bubbled out of the bottom of the pit and found its way toward
+the valley below through a crevice in the rock. In a short time
+Collins, under the influence of a right cold bath, sat up and
+addressed the boy in language which would not have been considered
+suitable in the presence of a lady.
+
+"You've done it now!" the alleged steam pump salesman cried.
+"You've dumped us into a pit in the heart of the Andes, and we'll
+starve before any one comes to our assistance. Take this strap off
+my wrists, or I'll have your life!"
+
+"You're an excitable party," Ned laughed. "You want your own way!
+I've been wondering, while I've been giving you first aid to the
+indignant, what your name really is, and where you live."
+
+"You'd better be trying to ascertain where we are," declared
+Collins, "and what chance we have of getting out alive."
+
+"I think I can tell you about where we are," Ned replied. "We were
+in the air not far from five hours. The Vixen will run about sixty
+miles an hour, therefore we are not fax from three hundred miles
+from Lima, in a southeast direction. Do you know if we are near any
+town?"
+
+Collins sulked a short time and then nodded toward a great peak
+which rose above all the others in the distance.
+
+"That may be Vilcanota," he said.
+
+"Old Vilcanota seems to be a whale," Ned observed, looking up at the
+snow cap.
+
+"Over 17,000 feet high," was the sullen rejoinder.
+
+"Well," the boy went on, "if that really is Vilcanota, we are still
+in the land of the living. In fact, we can't be more than
+twenty-five miles from a town, and there is a railroad--so my maps
+say--over to the east. It ends at Sicuani, and there the upper
+branch of the Uacayli river begins. This river empties into the
+Amazon at the head of steamboat navigation, the maps say."
+
+"You seem to know a lot about this part of South America," gritted
+Collins.
+
+"And over to the south," Ned went on, "is Lake Titicaca, and over
+the mountains from that body of water is Coroico, where the Beni
+river starts on its long run to the Amazon, by way of the Madeira
+river."
+
+"Well," snapped Collins, drawing hard at the strap which held his
+wrists, "you can't sit here and figure yourself out of this hole.
+Why don't you do something?"
+
+"Why, I thought it might be a good plan to wait until dawn," laughed
+Ned. "Then I may be able to repair this machine."
+
+"Repair nothing!" stormed Collins. "And in the meantime, I presume
+you think you are going to keep me tied up like a calf going to
+market?"
+
+"About that way," Ned responded, whereat the captive snorted out his
+rage and rolled over on his face and pretended to be asleep.
+
+In a short time dawn shone on the tops of the tallest mountains, and
+directly it crept slowly down into the pit where the wrecked
+aeroplane lay. By this time Ned had mapped out a course of action.
+
+The aeroplane he had seen in the night had descended not far from
+this spot, and he had decided to climb to some convenient height and
+look about for it. If he could come upon the Nelson, in good
+sailing condition, there would be no need of repairing the Vixen, or
+trying to do so.
+
+Collins had counterfeited sleep until, utterly exhausted, he had
+actually dropped off into slumber, so Ned had no captive to watch
+for the time being. Before leaving for a tour of inspection he
+examined the broken planes and discovered that it would be
+impossible for him to repair them, at least without the necessary
+tools and materials.
+
+Climbing to the level bit of sand, then, he faced the east and began
+the ascent of a mountain spur which seemed to reach the very
+heavens. It was a beautiful morning, the air being sharp and clear
+at that height. Ned felt that he could have enjoyed the beauties of
+nature more fully, however, if he had something in the way of
+breakfast!
+
+He climbed steadily for an hour, and then came to a narrow ledge
+which seemed to surround one of the lower peaks of the mountain.
+Passing around to the south, he heard a shout, then a fall--a
+bumping fall which told of a body bouncing from one rocky level to
+another.
+
+He ran around the angle ahead of him and came out on a shelf-like
+elevation from which a green little valley, half way up the side of
+the mountain, might be seen. In the center of the valley, carefully
+blocked against sudden motion, lay the Nelson.
+
+Ned could have danced with delight. The aeroplane appeared to be in
+perfect condition, but there was no one insight. Jimmie and Pedro
+must be about somewhere, the boy thought, as he considered the most
+practical way of reaching the valley, but where were they?
+
+He was about to call out in the hope of arousing one of the aviators
+to action when he saw a hand waving at him from underneath the gray
+planes. A more careful inspection of the spot revealed the dirty
+face of little Jimmie, who was lying on his face, an automatic in
+each hand. Pedro was nowhere to be seen.
+
+Ned watched the signaling hand for an instant and then, in response
+to what it said to him, scudded around the angle of rock by which he
+had reached the shelf. As he did so an arrow whizzed past his right
+ear and blunted against the rocky wall.
+
+The situation was not difficult to understand. Jimmie had dropped
+the Nelson into the little valley and had there been attacked,
+either by savages or those interested in the defeat of the Boy Scout
+expedition to Paraguay, though how the latter could have reached
+that lonely spot so soon after the landing of the aeroplane was a
+mystery which the boy could not fathom.
+
+Following the attack, Jimmie had hidden under the planes, and Pedro
+had probably taken to his heels. The situation explained,
+doubtless, why the boy had not returned with the airship. He had
+been held there by the enemies, virtually a prisoner.
+
+After a short pause, during which Ned listened intently for some
+sound of pursuit, the boy moved cautiously to the shoulder of rock
+and looked around it to the shelf. There was no one in sight, so
+he pressed on, and once more came within view of the aeroplane.
+
+Back of the planes he saw a head lifted from the lip of a gully
+which cut the valley like a trench. It was not the head of a
+savage, nor yet the head of a Peruvian mountaineer, for it was
+covered down to the eyebrows by a flat-topped leather automobile cap
+which was adorned with driving goggles! Evidently an American!
+
+While Ned, himself unseen, watched the cap and the goggles, the
+wearer lifted himself and looked up over the edge of the gully. He
+wore a gray suit, tailor-made, from all appearances.
+
+Back of him three ill-visaged Peruvian Indians also raised
+themselves to get a view of what was doing in front.
+
+So the savages were led by an American! Instead of the automatic of
+civilized warfare, the enemy was resorting to the poisoned arrow of
+the barbarian!
+
+An American there and in automobile costume! Where was the machine,
+and how in the name of all that was wonderful had it been brought to
+that rough country?
+
+And why were the enemies crouching there, when their only opponent
+was a boy, hidden if his position may be so termed--under the planes
+of an airship--planes which would offer little resistance to an
+arrow or a bullet?
+
+But while the boy looked and wondered a shot came from the very
+shelf on which he stood, and one of the exposed Indians dropped in
+his tracks. Then the situation became a bit clearer.
+
+Pedro had escaped from the valley to the shelf of rock, and was
+standing guard there shooting whenever the attacking party attempted
+to reach the aeroplane.
+
+In a moment the automobile cap and goggle and the evil faces of the
+Indians disappeared from view. The attacking party had dropped back
+into the gully, which was some distance from the machine.
+
+Waiting a moment, in order to make sure that no one was stirring
+behind the shoulder of rock, Ned called softly:
+
+"Pedro!"
+
+"Hello!" came the answer back.
+
+"'Where are you?" asked Ned, recognizing the voice of the Peruvian
+he had talked with at Lima.
+
+"In a notch of the rock," came the answer, in Spanish.
+
+Ned moved along the shelf, and soon came to where Pedro stood,
+sheltered by a jutting ledge. The journey was not accomplished
+without attracting the attention of the others, for an arrow whizzed
+past his head as he crept into the angle with Pedro.
+
+Pedro expressed great joy at the arrival of the boy, and explained
+that the situation as then shown had existed since dawn. On the
+afternoon of the previous day Jimmie, being then about to return to
+Lima, had found it necessary to land in order to repair a slight
+break in a plane.
+
+The driver of the pursuing Vixen, noting the temporary disablement,
+had circled around the valley for a short time and then returned to
+Lima. It was Pedro's idea that the Vixen would not return with
+assistance, but with enemies who would destroy the machine, leaving
+Jimmie and himself to find their way out of the mountains as best
+they could.
+
+Jimmie, Pedro said, had been unable to fix the Nelson for flight
+until about daylight, and then the attacking party had appeared.
+Since then it had been impossible to get the machine into the air,
+as every motion at the airship brought a bullet or a poisoned arrow.
+
+Just before Ned's arrival, an Indian had, by making a long journey
+around the cliff, gained the shelf of rock where Pedro was
+stationed, and been caught unawares and thrown down into the valley.
+It was the cry and the fall of this foe that Ned had heard.
+
+"But," Ned said, "the Vixen must have summoned some one active in
+the conspiracy before returning to Lima, for the man over there came
+in an automobile, and did not come very far either. He certainly
+did not come from Lima, which is more than three hundred miles
+away."
+
+"He might have come from Sicuani," replied Pedro. "That is over to
+the east, and not more than twenty miles off. I have heard that
+there is a path by means of which a motor car can reach this place.
+Yes, he must have gone to Sicuani, otherwise this man of the motor
+car would not be here," Pedro added.
+
+This cleared the situation not a little, and Ned was now encouraged
+to make an attempt to reach the Nelson, which Pedro declared to be
+in good condition for flight. If the others had come in an
+automobile, there could not be many of them. Probably not more than
+six in all, and two had been wounded, or killed.
+
+Pedro insisted that, with Ned guarding him from the shelf, he could
+reach the machine, but the boy thought it wiser to make the
+desperate journey himself. Even if the Indian reached the Nelson,
+the two of them might not be able to get the machine into the air,
+as Jimmie had had little experience in running a plane.
+
+So, after explaining to Pedro that he would be taken up later, Ned
+began the task of making his way down the almost perpendicular face
+of the cliff. Much to his surprise, there were no hostile
+demonstrations from the gully in which the attackers had disappeared
+a short time before.
+
+Instead of shots and the whiz of arrows, the boy heard, when half
+way down the slope, the distant whirr of a motor car!
+
+"There is some trick in the wind," Ned thought. "They would never
+run away in that manner because of the wounding of two Indians and
+the arrival of one boy from the outside."
+
+It was deathly still in the valley where the aeroplane lay. Sounds
+from a distance came with remarkable distinctness, so the popping of
+the motors of the automobile were plainly heard, and the direction
+taken by the machine was thus made known.
+
+Jimmie sprang up, uninjured, as Ned advanced and the two grasped
+hands with more than ordinary feeling. Almost the first thing
+Jimmie said was:
+
+"I saw the lights of the Vixen last night, but thought the other
+fellows would be in charge of her. How did you manage to geezle
+her?"
+
+"We stole her--and smashed her." Ned laughed, telling the remainder
+of the story in as few words as possible.
+
+Presently Pedro came down from the cliff and went over to the place
+where the man he had thrown down the declivity had fallen. He found
+him quite dead. With a solemn shake of the head he laid the body in
+a sheltered nook and joined the others.
+
+It took only a brief examination of the machine to show that she was
+in as good condition as ever, and Ned prepared to mount and leave
+the valley. Then the popping of additional motors broke out on the
+still air, and Jimmie grinned.
+
+"I guess you didn't smash the Vixen much," he said. "Anyway that
+man in the motor car seems to have repaired her broken wings.
+Probably had the tools to do it with him. They've got some dirty
+scheme on!"
+
+"Yes," Ned replied, grimly, "or they wouldn't have left the gully.
+Collins will be on deck again in about a minute!"
+
+
+
+
+CHAPTER IX
+
+A TRAGEDY IN THE AIR
+
+
+"Then we'd better be gettin' up in the air, so we can see what's
+going on," Jimmie replied. "I'd like to see where the motor car
+goes."
+
+"We can satisfy our curiosity on that point without going up in the
+air," Ned answered. "The Vixen was left just over that cliff.
+There is a valley--a dent in the slope of the mountain--on each side
+of that elevation, and the Vixen and the motor car are in one of
+them and the Nelson in the other."
+
+Jimmie started away on a run almost before Ned had finished
+speaking. In a few moments he was seen on the shelf, then he darted
+around the shoulder of rock and was lost to view. The popping of
+the motors continued.
+
+Ned hesitated a moment, uncertain as to the advisability of leaving
+the machine in the sole care of the Indian, and then followed. When
+he gained the shelf on the opposite side he saw the Vixen slowly
+lifting in the air. The automobile stood above her, on the level
+yet treacherous spot where Ned had landed. In it were Thomas Q.
+Collins and the man he had seen in the automobile cap and goggles!
+
+The Vixen did not look to be in good repair, just as Ned had
+supposed, for the newcomer had had only a short time to work over
+her, but for all that she was slowly leaving the narrow pit into
+which she had tumbled. Her motors were working, but did not appear
+to be doing any lifting.
+
+Then Ned saw that a rope attached to the machine was doing the work.
+The motor car, moving very slowly forward, was pulling her up the
+steep acclivity, her rubber-tired wheels drawing and bounding
+against the rocks.
+
+"If they get her up on that level space," Jimmie predicted, "they'll
+get her up in the air. You can see where they've been patching the
+planes, and the motors are workin' all right."
+
+"What I'm interested in, just now," Ned said, "is that automobile.
+I'd like to find the highway through which she entered that valley.
+It must be through some tunnel, for there's no path over the
+slopes."
+
+"Then we'll keep out of sight an' watch," Jimmie observed. "See
+there!" he cried, as the wheels of the Vixen struck the level area.
+"She'll be in the air directly. One of the niggers is gettin' in!"
+
+"What's that he's loading on?" asked Ned.
+
+"Stones, as I'm a living boy!" he went on, excitedly. "Jump for the
+Nelson, kid, and get her into the air! You see what they are going
+to do?"
+
+It was quite evident what the intentions of the others were. The
+Indians were loading the Vixen down with sharp-pointed stones and
+long wisps of dry grass; out from the nooks of the valley by
+Collins, who had now left the automobile.
+
+"We've just got to get the Nelson up in the air!" Jimmie cried.
+"They're gettin' ready to drop stones an' blazin' grass down on her
+planes. We've just got to get there before the Vixen sails over
+her!"
+
+Stopping no longer to observe the motor car, or watch her course out
+of the valley, both boys dashed around the shoulder of rock and
+began working their way down into the place where the Nelson lay,
+with Pedro, all unconscious of the approaching danger, sitting in
+the driver's seat and wondering if he was ever going to eat again!
+
+The whirr of the motors in the air soon told the sweating lads that
+the Vixen was rising from the ground. Just how they had managed to
+repair her so quickly was a wonder to Ned, but he had no time to
+consider that side of the case then.
+
+"Do you see her yet?" panted Jimmie, as the two paused a moment on
+their toilsome way downwards.
+
+"Not yet," was the reply, and Ned almost dropped a dozen feet and
+caught on the point of a rock which jutted out from the wall.
+
+"Gee!" cried Jimmie. "That was a tumble! Got a good hold, there?
+Then catch me!"
+
+Before Ned could remonstrate the reckless little fellow had dropped.
+The impact of his body forced Ned from the crevice in which he
+clung, and together they rolled down a score of feet, bringing up in
+an angle from which a fall would have been fatal.
+
+Ned came out of the tumble unharmed, but Jimmie lay like a rag in
+his arms as he straightened out and looked upward. The Vixen was
+rising over the cliff!
+
+Ned drew his automatic and fired three quick shots in the air, but
+the aeroplane sailed on, apparently unharmed. In a moment she was
+directly above the Nelson, and Pedro was fleeing for his life.
+
+Standing there helpless, with the unconscious boy in his arms, Ned
+saw the driver of the Vixen rain great stones down on the frail
+planes of the Nelson. Then a puff of smoke came from the driver's
+seat, and Ned saw that the wisps of straw were being ignited to
+finish the work begun by the rocks.
+
+He fired volley after volley at the man who was doing the mischief,
+but he was so unnerved and excited that his bullets went wild. The
+crash of stones on the breaking planes sounded louder to him than
+did the explosions of his own revolver.
+
+In a moment a blazing wisp of dry grass, or straw, dropped from the
+Vixen and sifted through the still air, the individual pieces of the
+bundle falling apart. Some of the little swirls of flame died out
+as the material passed downward, but others held, and dropped on the
+wounded planes!
+
+Ned shouted to Pedro, ordering him to smother else incipient blaze
+with his coat, or anything the he could find, but the Peruvian was
+nowhere to be seen. Terrified at the movements of the aeroplane, he
+had hidden in the rocks.
+
+Again and again the man on the Vixen lighted wisps of dry grass and
+hurled them down. Directly the planes were in a blaze. Ned laid
+Jimmie down on a narrow ledge and finished emptying his revolver,
+but to no purpose. He had never done such bad shooting in his life.
+
+But Fate was abroad in the Andes that morning!
+
+Presently the driver of the Vixen dropped his last wisp and shot
+upward, apparently not caring to engage in combat with the boy who
+had used him for a target so unsuccessfully.
+
+As the aeroplane passed across the top of the valley, Ned saw a
+little tongue of flame on the under plane. The driver evidently did
+not understand his peril, for he mounted higher and drove straight
+to the north.
+
+Ned watched the finger of flame grow as it bit into the fine fabric
+of the plane with something like awe in his heart. If the driver
+did not see his danger instantly and hasten down, nothing could save
+him.
+
+While the boy watched, almost breathlessly, Jimmie stirred and
+opened his eyes. He had a bad cut on his forehead, but otherwise
+seemed to have suffered little from his terrible fall.
+
+"Gee!" he cried, looking up at Ned with a grin. "I guess I took a
+drop too much!"
+
+Ned did not answer. He was too busy watching the tragedy which was
+taking place in the air. Jimmie followed the direction of his eyes
+and caught his breath with a gasp of horror.
+
+"He'll burn up!" he cried.
+
+Both planes were now on fire, and the driver knew of his peril. It
+seemed to Ned that the fellow's clothes were on fire, too, for he
+writhed and twisted about as he turned the aeroplane downward.
+
+"He'll get his'n!" Jimmie declared.
+
+The Vixen came down almost like a shot, leaving a trail of flame and
+smoke behind her. Then the end came.
+
+The charred planes gave way and the frame dropped, carrying the
+driver with it. They whirled over and over in the air as they came
+down. The fall must have been fully five hundred feet, and Ned knew
+that it would be useless for him to seek the man who had worked so
+much mischief to the Nelson with a view of doing him any service.
+
+Below, the Nelson was sending up sheets of flame. Pedro now ran out
+of his hiding place and attempted to check the fire, but his efforts
+availed nothing.
+
+"It is gone, all right!" Jimmie said, with a sigh. "Now, how are we
+goin' to get out of here? That's what I'd like to know."
+
+"We'll have to get out the same way the others do," Ned replied.
+"They have lost their aeroplane too."
+
+"Yes," agreed the little fellow, "but they have a motor car, and
+we've only our shanks' horses!"
+
+Ned extinguished the burning woodwork on the Nelson and made a hasty
+estimate of the damage done.
+
+"The motors are not injured," he reported. "If we can get something
+that will do for planes, we can get her out."
+
+"Then," said Jimmie, "I reckon it's me for the highway! I'll chase
+that automobile into where it came from. I'll bet I'll find cloth
+of some kind there."
+
+"It might be better to send Pedro," said Ned.
+
+"All right!" the little fellow agreed. "Then you and I can sleuth
+about this rotten country in search of gold! They say there's gold
+in these hills!"
+
+The purr of the motor car's engines now came again, and Pedro
+hastened up the ledge and followed down into the valley where she
+lay. In a moment she was out of sight, and the Peruvian was moving
+toward a rift in the wall of rock to the east.
+
+But Ned, watching from above, saw that there was only one person in
+the car. Mr. Thomas Q. Collins had been left behind!
+
+"That's strange!" Ned mused. "Why should he remain here? What
+further mischief has the fellow in mind?"
+
+When Ned returned to the machine he found Jimmie busy polishing the
+scorched steel work.
+
+"All she needs is new planes!" the lad cried.
+
+"Jimmie," Ned asked, "when you came here yesterday, did the Vixen
+follow you closely, or did she stand off and on, as seamen say, and
+take note of your course indifferently? What I want to know is
+this: Did the driver seem anyway excited when you speeded over this
+way?
+
+"He followed tight to my heels," replied the little fellow. "Then,
+when he saw me land, he whirled about and went away."
+
+An idea which seemed almost too good to be true was slowly forming
+in Ned's brain. Why had the Vixen always followed the Nelson? Why
+had she spied upon her without in any way interfering?
+
+Again, why had Thomas Q. Collins been left there in the wilderness?
+Surely there were no accommodations in sight in those valleys--nothing
+to subsist on, no shelter from the weather.
+
+He might, it is true, have remained out of a spirit of revenge,
+hoping to punish Ned for his treatment of him, but this explanation
+did not appeal to the boy. With the Nelson hopelessly out of
+repair, he could well afford to leave the lads to their fate, as the
+chances that they would be able to get out alive--being strangers to
+that country and, supposedly, to mountain work--were about one to
+ten.
+
+And so, Ned reasoned, there must be some other incentive for the
+action taken by Collins. He had a subconscious impression that he
+knew what that incentive was, but hardly dared to whisper it to
+himself.
+
+The boy's reverie was interrupted by Jimmie, who had been running
+back and forth in the valley in quest of wild berries, or something
+which would serve as food.
+
+"I could eat a whale!" the little fellow shouted.
+
+"Catch a hare and cook him," Ned suggested.
+
+"The hares here are not exactly like our rabbits, but they are good
+to eat. If you go over into the little jungle below, at the end of
+this bowl, you might find one."
+
+Ned, still wondering if what he hoped might be true, turned to the
+cliff which separated the two valleys and began a careful inspection
+of the rock formation. Away around to the east, under the shelf
+which ran like a terrace around the elevation, he came upon what he
+was looking for.
+
+The shelf extended outward from the face of the rock, and under it,
+setting back into the cliff perhaps a dozen feet, was a cavern which
+looked out on the valley where the Nelson lay, but from which the
+machine itself was not in sight.
+
+The floor of the cavern showed traces of human habitation. It had
+undoubtedly been occupied as a shelter from storms by mountaineers
+for centuries.
+
+But the evidences of occupation which Ned saw were not those showing
+distant use. There was a tiny fire burning in a crevice which
+served as a chimney, carrying the smoke far up into the sky before
+discharging it.
+
+Scattered about the fire were tin cans, some empty, some containing
+food of various kinds. Thrown over a heap of broken boxes in a
+corner was a coat--a tailor-made coat of fine material.
+
+On a little ledge at the rear were a safety razor, a small mirror,
+and a shaving mug. Ned picked up the coat and thrust a hand into an
+inside pocket. That, he thought, would be an easy way to ascertain
+the identity of the owner.
+
+In a moment he drew forth a folded paper, covered with figures in
+pencil. The figures were in columns, as if the maker had been
+setting down items of expense and adding them up. The total was in
+the millions. The calculations of a cattleman, covering shipments
+and receipts!
+
+Ned continued his search of the coat and presently came upon a
+packet of letters, all enclosed in envelopes and neatly ticketed on
+the back. They were enclosed in a rubber band, and showed careful
+handling.
+
+And the envelopes, every one of them, were addressed to Dr. Horace
+M. Lyman, Asuncion, Paraguay!
+
+
+
+
+CHAPTER X
+
+DINNER IS SERVED
+
+
+Ned stepped to the mouth of the cavern and looked out. Jimmie was
+making his way back to the machine, empty handed and evidently
+dejected. Ned gave a sharp whistle and beckoned to the lad when he
+looked up.
+
+He did not care to make any unnecessary noise there, for he believed
+that Collins was not far away.
+
+He was now half convinced that Lyman had been secreted in that
+vicinity after being abducted from Paraguay; that he had been
+closely guarded and comfortably provided for, the idea being to keep
+him out of Paraguay until his concession reverted to the government.
+
+It was his notion, too, that Lyman had inhabited this cavern until
+the appearance of the Nelson, when he had been removed by his
+attendants and placed in custody in some other natural hiding place.
+
+Whether he was still in that locality the boy could not say, but of
+one thing he was certain. That was that Lyman had not been taken
+away in the motor car.
+
+And so the quest had been shifted! There would now be no need of
+proceeding to Asuncion. Probably to prevent getting mixed up in the
+crooked game, the plotters in Paraguay had ordered those interested
+in the disappearance of Lyman to get him out of the alleged
+republic.
+
+This would account for his being in the mountains of Peru. It might
+also account for the presence in Lima of the Vixen and Mr. Thomas Q.
+Collins.
+
+The telegrams without meaning which Ned had received on his arrival
+at Lima pointed out the fact that the conspirators knew that the
+Nelson was heading for that city as a base of operations. Ned's
+receipting for the telegrams was proof positive that he had arrived.
+
+"A very pretty plot!" Ned thought, as he waited for Jimmie to make
+his way up the face of the cliff to the mouth of the cavern.
+
+"Gee!" the little fellow cried, as his head showed above the level
+of the floor of the hiding place. "I never was so hungry in me
+blameless life!"
+
+Ned backed up so as to conceal the tinned food.
+
+"What will you give for a couple of tins of pork and beans?" he
+asked, with a provoking smile.
+
+"I'll sign a check for any amount!" grinned the boy.
+
+Ned stepped aside, disclosing the food, and handed Jimmie a small
+hatchet which he had found under the rubbish.
+
+"Go to it!" he said.
+
+Jimmie almost dropped with amazement. It was like getting water out
+of the desert. Like finding milk in the heart of a rock. Like
+uncovering snowballs from a bed of hot coals! American tinned goods
+in the mountains of Peru!
+
+The boy examined the cans attentively. They were all correct on the
+outside. Then he cut one open with the hatchet and brought out a
+spoonful of beans on the corner of the implement.
+
+"Wow!" he cried, in a moment. "They're all right! Come on an' fill
+up!"
+
+Both boys fell to, and the supply of tinned food was considerably
+diminished before they had finished their breakfast. Then, fearful
+that the owners of the food might seek to remove it before another
+meal time came, they carried a considerable portion of the cans away
+and hid them in a small cache near the Nelson.
+
+"We won't starve for a few days," Jimmie said, when this work had
+been finished.
+
+"Now, tell me what it all means. I wanted to ask you before, but,
+somehow, I couldn't keep my mouth empty long enough to talk. What
+about it?"
+
+"I think," Ned replied, "that we have blundered on the country
+residence of Mr. Horace M. Lyman!"
+
+"What does he come up here for?" asked the little fellow. "Ain't he
+got no sense?"
+
+"The decision wasn't up to him, I take it," laughed Ned. "The
+schemers in that crooked little country wanted to get him out of the
+way, so they wouldn't be getting into a quarrel with the little old
+U. S. A."
+
+"I don't see him anywhere around," the other said.
+
+"He doesn't seem to be on exhibition, and that's a fact," Ned
+replied.
+
+"Perhaps," Jimmie grinned, "we'd better look up this Thomas Q.
+Collins! I guess, he could lead us to him."
+
+"No doubt of that," Ned admitted.
+
+Having securely hidden the tinned food, the boys still lingered in
+the vicinity of the Nelson. The machine lay shining in the
+sunlight, seeming to look reproachfully up at the boys, accusing
+them of getting her into a very bad predicament.
+
+"Good old girl!" Jimmie cried, stroking the motors. "We'll get you
+out of this mix-up, all right!"
+
+"If we do," Ned replied, studying the ground about the machine,
+"we'll have to get cover somewhere and watch her night and day."
+He pointed to footprints close up to the motors as he spoke, and
+Jimmie began measuring the impressions in the soft earth.
+
+"They've been here since we landed, all right," the boy exclaimed,
+in a minute. "We never left these tracks. They're big enough for
+an elephant to make!"
+
+"They were made by muckers," Ned continued. "You know the kind of
+shoes the men who work in mines wear? Big ones, looking more like a
+mud scow than a shoe. They have turned some of the copper workers
+loose on us, little man."
+
+"Gee! How long will it take Pedro to get back?"
+
+"Probably three days, if he has no bad luck--if they let him come
+back at all," Ned answered.
+
+"You can take it from me that they won't let him come back at all if
+they have anything to say about it!" the lad muttered. "I reckon
+I'll have to go an' find him."
+
+"I think it will take both of us to prevent the Nelson being broken
+up," was Ned's reply. "We shall, as I have already said, have to
+guard it night and day. And, besides, we've got to keep out of the
+way of bullets and poisoned arrows."
+
+"This is a cute little excursion, when you look at it up one side
+and down the other," Jimmie grunted. "We've left Leroy in trouble
+at Lima, and we've got the Nelson all banged up. Perhaps they'll
+hang Leroy before we get back!"
+
+"Cheer up!" laughed Ned. "The worst is yet to come!"
+
+"And here it comes!" cried the little fellow, as a handkerchief
+which might once have been white fluttered above a boulder not far
+away, held aloft and waved frantically back and forth by a hand
+which could only faintly be seen.
+
+"Come on out!" Ned shouted.
+
+A figure lifted from behind the rock and stood straight up, waving a
+dilapidated slouch hat, now, instead of a handkerchief. The fellow
+wore a suit of clothes which was much too small for him, so that his
+wrists and ankles protruded a good six inches. The clothes were
+dirty and ragged too, and the man's face looked as if it had been a
+long time since it had been brought into contact with water.
+
+At a motion from Ned he advanced toward the machine. Ned thought he
+had never seen a sadder face on a human being.
+
+"Looks like Calamity!" Jimmie muttered
+
+"Have you boys got anything to eat?" asked the stranger, rubbing his
+palms over the waist band of his ill-fitting trousers.
+
+"You look like you needed something to eat!" Jimmie put in. "How
+long you been sleuthin' at us from that rock?"
+
+"Not long," was the reply, in a slow, sober tone. "Just a minute.
+I fell down a mountain not so very long ago."
+
+"Then," said Jimmie, pointing to the wound on his head, "you haven't
+got anything on me. I'm quite a hand at fallin' down precipices,
+myself!"
+
+"You didn't say if you had anything to eat," insisted the stranger.
+"I'm so hungry that I could eat a fried griddle."
+
+"Well," replied Ned, "we're just out of fried griddles, but we've
+got a tin of beans we might give you."
+
+"Slave for life if you do!" drawled the other. "I've been wandering
+in the mountains for more than a week, and am so empty that it will
+require several tins to fill me up, but if one is the limit, why--"
+
+Jimmie uncovered the cache and brought out a can of beans, which he
+opened with the hatchet and presented to the other, with a grave
+bow.
+
+"Dinner is served, me lud!" he said.
+
+The stranger did not wait for formalities. He had no knife, fork,
+or spoon, but he managed to remove the beans from the can and convey
+them to his mouth without the aid of such artificial aids to the
+hungry. He sighed when the can was empty, and wiped his hands on
+the grass at his feet.
+
+"How did you get in here?" asked Ned, then, curious to know how any
+one could have the nerve to face a mountain journey in the condition
+this man was in.
+
+"I came after the mother lode," was the reply.
+
+"Have you got it in your pocket?" asked the little fellow.
+
+"I didn't say I found it," was the grave reply. "I said I came in
+here looking for it. There was a party left Sicuani, over to the
+east, two weeks ago, and I trailed in behind. You see, I had a fool
+idea that these people were on the track of a big gold find, and so
+just naturally sneaked along. They had an automobile. I walked.
+They had plenty of provisions. I had no one to grub-stake me. They
+feasted while I starved, but the way is rough and slow, especially
+when tires break, and I managed to keep up with them until two days
+ago. Then they got away from me."
+
+"Did you find gold?" asked Ned.
+
+The stranger shook his head.
+
+"Nothing doing!" he said. "I've been grubstaked all over Australia,
+and up the Yukon, and over Death Valley, but I have never found a
+spot where there's so little gold as there is in these hills."
+
+"So, you are an American tourist?" asked Ned.
+
+"I am," was the grave reply. "I stowed away on a ship bound for
+Asuncion and got a job shoveling coal to pay for the rottenest grub
+I ever ate. When we got up the river to Asuncion I hired out to a
+man to herd cattle. That was worse, only the air was not so
+confining."
+
+"So you left and went to Sicuani?" asked Ned.
+
+"Exactly, after many days. I liked the cattle business all right,
+but I had to move on. Horace M. Lyman is a good chap to--"
+
+"Wait!" Ned said. "It was Horace M. Lyman you worked for, eh?"
+
+"Sure. He's an American, and a fine fellow."
+
+"Well," Jimmie cut in, "you're likely to see him if you stick around
+here. They geezled him, so another gazabo could get his
+concession."
+
+"And marooned him off here? Is that it?" asked the stranger.
+"Well, there's a pair of us, then, that don't find anything
+nourishing in the scenery. Where is he?"
+
+"We haven't found him yet," Ned answered, "but we're on the trail.
+If you had one more can of beans, do you think you could help us
+hunt him up?"
+
+"Certainly. Of course. I'll do that without the beans, but--"
+
+"I see," Ned answered. "You haven't the strength, just now, to do
+much looking. All right, we'll fat you up, and then--"
+
+Ned did not complete the sentence, for a long, wavering call came
+from the west, and the stranger started off in that direction
+without a word of explanation. Ned wondered for a moment whether
+this fellow wasn't another hypocrite of the Collins stripe.
+
+"Wait a minute!" he exclaimed. "Suppose you tell us something about
+that call?"
+
+"I'm agreeable," replied the other. "Don't you know what that
+coo-coo-ee-ee is? Then you've never lived in the cattle country.
+That is a cowboy salute, pard, and my private opinion is that Horace
+M. Lyman is the party that uttered it."
+
+"Then he's not far away," Jimmie said.
+
+"Suppose I answer him?" asked the stranger.
+
+"Go on an' do it," the little fellow advised, and Ned nodded.
+
+The cod-coo-ee-ee which the ex-cowboy emitted rang through the
+valley and came back in weird echoes from the crags around.
+
+"Now he knows there's some one here looking after him," the stranger
+explained. "He knows that Old Mose Jackson is right on the job.
+What might your name be, pard?" he added, turning to Ned.
+
+"Nestor," was the reply.
+
+"Ned Nestor, of course!" Jackson exclaimed. "I read about you being
+in Mexico, and in the Canal Zone. Strange I should bump into you
+away off here! And I'll bet this is Jimmie? What?"
+
+"The same!" the little fellow replied. "Ned can't lose me!"
+
+Hardly had the words left the boy's mouth when a bullet came zipping
+through the air. It struck a metal section of the Nelson and
+flattened out.
+
+"Before now," Jackson said, coolly, "when I've found myself on the
+open plain with redskins popping away at me I've dug a hole in the
+ground and stowed myself away in it. What do you think of the
+notion, pard?"
+
+"It looks good to me!" Jimmie cried. "But," he went on, "We've got
+nothing to dig with, so we'll just have to move back to that gully,
+an' take the grub with us."
+
+The change was soon made, the Nelson being run back to the edge of
+the trench-like depression, and then the three awaited the next move
+on the part of the enemy.
+
+Presently a shout was heard, and then the flashily-dressed figure of
+Mr. Thomas Q. Collins appeared on the shelf of rock.
+
+"Don't shoot!" he cried, swinging both hands aloft. "I want to come
+down and talk with you."
+
+"There's some trick in that!" Jimmie said.
+
+
+
+
+
+CHAPTER XI
+
+A STICK OF DYNAMITE
+
+
+"If we could only get out of this cul-de-sac," Jack said, as the
+savages gathered closer about the Black Bear, "and make the Beni
+river, we could leave them behind like they were painted on the
+trees."
+
+"There ought to be some way," Frank mused.
+
+Harry, who had been rummaging in a trunk of clothing and tools which
+stood under the bridge which half concealed the motors, now came
+forward with a package in his hand.
+
+"What is it?" asked Jack.
+
+"Dynamite!" was the cool reply.
+
+"That ought to induce them to go on about their business--if
+properly administered," Jack said. "I didn't know we had any on
+board."
+
+"I didn't know what we might come across up here," Harry replied.
+"Shall we light a fuse and give one of these persuaders a toss over
+into that mess?"
+
+"It would amount to wholesale murder," Frank replied.
+
+Harry's face hardened as he held up a hand for silence. The howling on the
+banks of the little stream was now almost deafening, and every second there
+came the thunk of arrows against the boat.
+
+"You see what they would do to us," he said.
+
+"Yes, I know," Jack said, "but we are supposed to be civilized! It
+would be a wicked thing to do, to murder fifty or a hundred of those
+savages. Suppose we toss a stick where it will do little damage and
+still attract their attention from the boat? Then we might get that
+log out of the way."
+
+"We'll see what show we have for getting it out of the way-the log,
+I mean," Jack replied.
+
+He cautiously opened one of the lower panels at the rear and looked
+out. The log which blocked the narrow channel was afloat, for it
+was the trunk of a dry tree, and the water was deep. What held it
+in place was the end which lay on the shore. It had been rolled in
+at a point where the bank was low, and at least two-thirds of it lay
+on the ground.
+
+"I'd like to know how they got it in there!" Jack said. "It looks
+too big for a hundred men to handle."
+
+"Anyway, there it is," Frank replied, "and there the propellers
+are--one of them broken. Can we make speed with that busted wing?"
+
+"We've got to," Harry said. "Just hear the devils! They will rush
+the boat in about a minute!"
+
+The cries coming from the forest were now blood-curdling in their
+ferocity. The cannibals were evidently working themselves into a
+pitch of excitement which would give them courage to charge the
+Black Bear.
+
+Now and then the frightened howl of some wild beast was heard in the
+distance, adding not a little to the excitement of the scene. The
+tree which had been set on fire to attract the attention of the
+airship still blazed, sending a twist of flame far up into the sky.
+
+In the glare of the fire the savages looked like fiends ready for
+any act of deviltry. Now and then three figures larger than the
+rest stood together as if in conference, and then the shouts grew
+louder, and the line about the boat closer drawn.
+
+"I've got a notion that we can make pretty good speed with that
+broken wing," Jack mused. "Anyway, we can drift down stream if we
+can't steam up stream, and that will take us out of this mess."
+
+"Then let's blow that log up with dynamite," suggested Frank.
+
+"Yes," said Jack, "and finish the propellers!"
+
+"Blow up the shore end," continued Frank. "Who can pitch it so that
+it will knock that blooming dry wood into the stream?"
+
+"I'm willing to try," Harry said. "I used to pitch a tricky ball!
+I'll get a fuse ready, open a panel, and give it a throw. While I
+have the panel open, though, you fellows open up a loophole in front
+and do some shooting out of it to attract attention. I don't want
+any poisoned arrows biting me."
+
+This was agreed to, and Harry arranged a fuse and prepared to throw
+it. When Jack opened a panel in front and sent a volley of bullets
+ashore, the boy pushed open a panel in the rear and, waiting until
+the attention of the savages was attracted to the front of the boat,
+tossed out the dynamite.
+
+It hurled through the air, flashing in the red light of the fire,
+and landed at the very end of the fallen tree, rolling into the
+angle between the wood and the earth. A fine throw!
+
+Harry yelled to Jack to close his panel, and all three boys stood on
+the tips of their toes, fingers in ears. In a moment the explosion
+came.
+
+The Black Bear rocked violently, so that it was with difficulty the
+boys kept their footing. Wild cries of distress and fright came
+from the forest, and, in a few seconds, the crash of falling trees.
+The dynamite had done its work well, at least, so far as noise was
+concerned. They could not yet see what effect the explosion had had
+on the tree.
+
+Had it loosened the obstructing log so that the boat could pass out
+into the Beni river? Had the concussion damaged the propellers so
+that the trip up the valley of the Amazon would have to be
+abandoned?
+
+These questions were in the minds of all three boys as Jack
+cautiously opened a rear panel and looked out. The first thing he
+saw was the log, splintered and broken into half a dozen pieces,
+floating down stream.
+
+The explosion had whirled the great trunk high up in the air and
+brought it down, broken, in the channel of the stream. There seemed
+nothing to do now but to set the motors at work and run out of the
+dangerous position.
+
+But the motors refused to work. Something more than showed on the
+surface was the matter with them. Harry looked out at the rear and
+saw a great red patch of earth without a single human being in
+sight. The fire was still burning brightly, but there were no
+savages dancing about in its fierce light.
+
+At the sound of the explosion the head hunters had taken to their
+heels. At first view, no one seemed to have been injured by the
+dynamite, but, on giving the scene a closer inspection, the boy saw
+three bodies lying near where the log had been. They might be dead
+or only stunned; the lad had no means of knowing.
+
+While Harry watched for some sign of life, the roar of a wild animal
+came from the forest, and he knew that a tiger cat was approaching.
+The humans--if the man-eating savages may be so termed--were still
+running, it appeared, while the wild beasts of prey were returning
+to the scene of the explosion.
+
+"Come," Harry cried, "we must get out of this now if we can get the
+propellers to working. There is no one in sight, only three men
+lying near where the log lay, and there are man-eating animals
+coming, so I'd rather not see what takes place next."
+
+Jack threw open another panel and stepped out. The roar in the
+forest was growing again, but no savage was in sight. He moved to
+the back of the boat and bent down to look at the propellers.
+
+"I can't see from here!" he shouted, in a moment. "Look out for me,
+you fellows!"
+
+Like a shot he was in the river, diving under the stem of the Black
+Bear. Harry and Frank, knowing the rivers of that district to be
+swarming with caymen, grouped at the rear and watched with anxious
+eyes for the reappearance of their chum.
+
+In a few seconds Jack's face appeared above the surface of the
+water. He seized a rope passed to him and climbed on board, shaking
+the water from his clothing like a great dog.
+
+"It is all right," he said, as soon as he could get his breath.
+"There was a piece of the log wedged in back of the paddles and I
+got it out. Get a pole and push. She's in the mud, I guess."
+
+The pole was used before the motors were turned on again, and the
+Black Bear was soon out of the little creek, sailing slowly down the
+Beni. However, the boat did not behave well, and it was decided to
+tie up for a day and go over her carefully. The propellers needed
+fixing, and there might be some other injury which had not been
+discovered.
+
+Not caring to strain the weakened propellers, they permitted the
+boat to drift down stream.
+
+When a mile away the illumination of the fire which had been so
+injudiciously set could still be seen distinctly, and when the boys
+listened they could hear the cries of the savages and the fierce
+howls of the wild beasts.
+
+During the day the boys had passed a level plateau on the east bank
+of the river, and it was decided to float down to that, as they
+could beach the Black Bear there and work without danger of being
+attacked from the shelter of a forest.
+
+They gained the spot about midnight and anchored some distance out,
+resolved to take no chances on the shore that night. The stream was
+quite wide, and they opened the top panels so as to get what fresh
+air they could.
+
+Jack was the first one to see the airship hovering over them.
+
+"Look!" he cried. "Look! Look! We've just got to attract their
+attention in some way! See! They are going away again! Confound
+the luck!"
+
+The airship seemed about to dip down, then it floated off to the
+west and whirled to the south.
+
+"They're signaling!" Harry cried.
+
+This seemed to be true, for there were lights moving about in the
+air in queer combinations.
+
+"Get a glass!" shouted Jack, in great excitement. "We'll soon see
+about this!"
+
+But the airship seemed interested in the spot where the fire was
+burning, and did not remain overhead long enough for the boys to get
+a good view of her. At last she disappeared entirely.
+
+Although anchored out in the stream, which was at least two hundred
+feet wide at that point, the lads kept a close watch of the shores
+that night. Once, just before dawn, they caught the sound of
+paddles, but the canoe which appeared on the west soon sneaked away.
+
+The hubbub on shore kept up all night long. The beasts took up the
+chorus when the savage tribesmen retreated.
+
+"Beautiful country this!" Jack said, as the sun rose over the great
+valley. "I think I'll like to live here always--not!"
+
+"Yes," grunted Frank, whose eyes were heavy with the long watch,
+"even on the Great White Way, the enthusiasm quiets down after three
+o'clock."
+
+"It is all in the game!" grinned Harry. "We came out here for
+excitement, and you mustn't complain when you get it."
+
+After breakfast, which was keenly enjoyed, the Black Bear was
+beached on the cast banks and the injury to the propellers examined.
+Some of the blades were broken while others were strained.
+
+"Well," Harry said, as he scratched his head in deliberation, "we've
+got extra blades, and we've got the tools, and I don't know as we're
+in a hurry anyway. We've got all the time there is!"
+
+"Not if we catch the Nelson before it gets out of the country," Jack
+objected. "This is the 22d of August, and the Nelson must have
+sighted Lima about the 14th, so you see we've got to do some sailing
+if we get to the headwaters of the Beni before the boys get back
+home."
+
+If they had only known, the lads might not have been so anxious to
+get on, for the boys with the Nelson were having troubles of their
+own about that time. Besides, there were difficulties ahead much
+greater than those entailed by the breaking of the blades of the
+propellers.
+
+They worked all day at repairing the injuries, and at night were
+ready to proceed. It was dark again, and there seemed to be a great
+commotion on shore.
+
+"For one," Frank observed, "I don't like the idea of going on up an
+unknown river in the night. There are rapids, and there may be
+obstructions. And then we may follow off some tributary which will
+land us in some swamp after an all night ride."
+
+"I'm not anxious to go on tonight," Harry contributed, "for I'd like
+to see what that mess on shore will amount to. There's something
+besides the appearance of the Black Bear exciting those fuzzy little
+natives, and we may miss something if we run away. I wouldn't like
+to do that."
+
+So it was decided to remain where they were until morning. The
+panels were put up, leaving only the openings for ventilation, and
+the Wolf was brought close alongside.
+
+Frank got the first watch in the drawing of sticks, and stationed
+himself at the prow, where he could look out on the river. Jack and
+Harry were soon asleep.
+
+About midnight a great clamor arose on the west bank. In a moment
+it was echoed from the opposite shore. There was a beating of
+drums--the foolish drums which the natives made so crudely--and long
+chants, rising in the darkness like the monotonous melodies the boys
+had heard in the cotton fields of the South.
+
+Frank shook Jack and Harry out of their bunks, much to the disgust
+of the two sleepy-heads. They did not need to ask questions as to
+the reason for this, for the chant was coming nearer, and the drums
+were beating like mad.
+
+"They're arranging an attack!" Jack said, turning a searchlight out
+of the front loophole. "I can see half a dozen canoes hanging off
+and on at a bend above. I guess we made a mistake in stopping
+here."
+
+"Perhaps we'd better drop down the river," Harry suggested. "I
+don't want those heathens swarming over the Black Bear."
+
+Jack went to the stern and looked out on the swirling river from
+that point.
+
+"If we do," he said, in a moment, "we'll bunt into a fleet of war
+canoes. We've got to put on all speed and drive ahead."
+
+"Why not drop back?" asked Harry.
+
+"Because," was the reply, "we can go up stream about as fast as we
+can go down stream, and the canoes can't. We'll shut everything
+tight but the loopholes and go through them like a shot through
+paper. If they board us we'll have to open up and drop them into
+the river with our automatics."
+
+"Put the big light out in front then," Harry said, "and stand there
+and tell me which way to steer, and let her go!"
+
+The next moment the Black Bear, closely followed by the Wolf, was
+nearing the canoes, now drawn up in line of battle in front.
+
+
+
+
+CHAPTER XII
+
+A BRIBE OF HALF A MILLION
+
+
+"What do you want to talk about?" asked Ned, as Thomas Q. Collins
+advanced a step, both hands still high above his head, as an
+indication that he was unarmed.
+
+"I want to reach an understanding with you," was the reply.
+
+"About what?"
+
+"About--well, about your errand here."
+
+"Oh! Well, what about it?"
+
+Collins hesitated a moment and then asked:
+
+"Why can't I come to you and sit down? I'm not armed. This is not
+an easy or a dignified position for me to hold."
+
+"You say you are not armed," Ned replied. "Will you say as much for
+the savages who are with you in this dirty game?"
+
+"There are no savages here with me," Collins protested. "Your
+Indian killed one by throwing him from the ledge, one was killed
+when the Vixen burned and dropped, and one was shot by one of your
+boys. The other went away with the motor car. You must have seen
+them riding away?"
+
+"There were five people with him when he first came out here in the
+car," Jackson said, under his breath. "Ask him where the other
+white man now is."
+
+"Did you see the other white man?" asked Ned of Jackson.
+
+"Not distinctly."
+
+"Would you have recognized him if it had been Lyman?"
+
+"I might. I can't say. I wasn't very near to them. They kept me
+scouting over the hills to keep them in sight."
+
+"Well," Collins called out, impatiently, "are you going to let me
+come in for a talk? If not, I'll go back and bring some shooters
+out here."
+
+Without answering that special question, veiled, as it was, with a
+threat, Ned asked the one proposed by Jackson.
+
+"Where is the white man who was with you when you first came here in
+the car?"
+
+"I did not come in a motor car," was the reply. "I came in the
+Vixen."
+
+"That's a lie!" Jackson whispered. "The Vixen, if that is what they
+call their airship, never showed up until a few days ago. I tried
+to signal to the driver; or, rather, I did signal to him, but he
+ignored me. This man Collins came in with the car more than two
+weeks ago, and went out in it, too, and the other white man
+remained. The next time he came, he was in the Vixen."
+
+"Who is that fellow who is filling you with prejudice against me?"
+demanded Collins, presently. "It looks like a man wanted for
+stealing cattle from the Lyman ranch."
+
+"Why didn't you communicate with him, if you were so hungry?" asked
+Ned of Jackson, suspiciously. "You say he has been here at least twice."
+
+
+Jackson frowned and looked away. Then his forehead flushed and he
+said:
+
+"I guess there's no use lying about it. I was accused of running
+cattle off the Lyman range. That is the man who accused me. I
+never did. He knows that. Now you know why I didn't approach him
+and ask for food."
+
+"Well," insisted the boy, "why didn't you browse around and find the
+white man he left here? That is what he came in here for, isn't it--to
+hide some one he wanted out of the way?"
+
+"I thought he came to look for gold," was the reply. "Now, about
+the other question. I did try to find the man he left here. I
+wanted to eat with him! I knew there was some one in the hills, but
+I never found him. It beats the Old Scratch where he is!"
+
+"Come, come!" Collins cried, impatiently, "you can do your visiting
+after we have our talk. Shall I come to you, or will you come to
+me?"
+
+"Don't you go out there!" Jimmie warned. "He's got some one hidden.
+You'll be shot if you do. Tell him to come here."
+
+"Keep your hands up and come here," Ned ordered, thinking this good
+advice.
+
+He had already experienced the treachery of the fellow, and did not
+care to take any chances. Collins came along sullenly, stood stock
+still, while Jimmie searched him, and then sat down on the framework
+of the Nelson.
+
+"That aeroplane would look handsomer," Ned said, grimly, "if your
+men had not set it on fire."
+
+"That was war!" Collins replied. "It is war still, unless we can
+come to some kind of agreement."
+
+"I haven't much faith in your word," Ned replied. "You played a
+dirty game on me at Lima, you know."
+
+"The chances of war!" Collins replied. "Now," he went on, "we can
+come to terms without any reference to the International Peace
+Congress, if we want to. I'll admit that if things were a little
+different I wouldn't be asking for terms, but that is neither here
+nor there. I want your assistance."
+
+"On the level?" demanded Jimmie.
+
+Jackson grinned scornfully, and Collins glared at both.
+
+"The man we brought out here--merely as a matter of business--has
+disappeared," Collins went on. "We left him in the little cavern
+where you found his coat and the food. He's got away."
+
+"You refer to Lyman?"
+
+"Of course."
+
+"You were keeping him a prisoner until his concession should lapse?"
+
+"That's only business."
+
+"When does it lapse, in case he does not appear and make payment?"
+
+"On the 31st of August."
+
+"And this is the 18th?"
+
+"I think so. I'm pretty well mixed as to time, as well as
+everything else."
+
+"Then he has only fourteen days in which to get back to Asuncion and
+make a large payment?"
+
+"That is just it."
+
+"And he is lost?"
+
+"Yes."
+
+"When did you see him last?"
+
+"You remember how I came to be here? You brought me, trussed up
+like a hen in that aeroplane harness. Well, when the Vixen went
+into that pit and you went away to look over the scenery, I knew
+that the motor car would be along soon, so I didn't try to get away.
+I knew what would happen if I did. You'd shoot! Just as soon as
+the car came and I was released--the car brought in food for
+Lyman--I sent a man over to the cave to find Lyman. He wasn't there.
+Understand? He wasn't there."
+
+"But there were live embers in the cave when I got there," Ned said.
+
+"I know. That was built by one of my men, who wanted to make
+coffee, but didn't. The food you stole was brought in by the car as
+I said before. You found Lyman's coat, didn't you?"
+
+"Yes, and a packet of letters."
+
+"I knew what you were in Lima for from the first. I knew of your
+mission before you left San Francisco. So I did not lie to you when
+you asked if the man who was brought in, something over two weeks
+ago, in a motor car was Lyman. I knew that you knew. You see, we
+had to get him out of Paraguay when it was learned that the United
+States had placed the Lyman affair in the hands of the Secret
+Service."
+
+"Go on," Ned said. "You are getting pretty close to the point now."
+
+"I thought at first," Collins went on, "that you had blundered into
+this district just by blind luck. Now I know better. I gave myself
+away by my fool antics at Lima. Then the Vixen showing up and
+chasing the Nelson around increased your suspicions. Oh, I know how
+it happened. You fooled us all. We led you right to the spot where
+Lyman was hidden by our attempts to mislead you. More fools we!"
+
+"You have stated the case correctly," Ned said. "If you had kept
+away from me at Lima, and the Vixen had kept out of sight, I should
+have gone straight on to Asuncion, and should have been wasting my
+time there this minute."
+
+"Yes, that's the truth! Well, now I've been perfectly frank with
+you, and I want you to be equally honest with me. Do you know where
+Lyman is?"
+
+"I do not."
+
+"You haven't seen him?"
+
+"Never saw him."
+
+"If you find him, what do you propose doing?"
+
+"I shall take him back to Asuncion and see that he gets justice."
+
+"Acting as a Secret Service man of the United States?"
+
+"No, as an individual."
+
+"But you are in the employ of the government?"
+
+"Yes, but I'm not authorized to mix the two countries up in a war."
+
+"Yes, I know, but your government will back you in whatever you do.
+That is the point with me. If you report no cause for interference
+down in Paraguay, there will be no danger of our getting into
+trouble. Your government wouldn't make a demand for Lyman's
+release, although it was understood he was kept in duress by a high
+official of the republic. Still, it sends you out to act
+unofficially. Now, this being the case, you are the person I want
+to talk with."
+
+"Well?"
+
+"I want you to help find Lyman, and then I want you to help me come
+to terms with him--we can't fight the United States!"
+
+"In other words, you want me to betray my trust and help you rob
+him?"
+
+"No. There are two sides to everything--where there are not three,
+or more. So there are two sides to this cattle concession business.
+I think that Lyman will be glad to settle if we find him--if he does
+not know that the United States has Secret Service men on the
+ground!"
+
+"So you really do want to buy my silence?"
+
+"I want to make sure that you will not attempt to defeat our plans."
+
+"Nothing doing," Ned replied.
+
+"Wait!" Collins continued. "You haven't heard me out. We'll see
+that Lyman gets all his money out of the deal, with something
+besides, and also that you get a quarter of a million dollars for
+saying nothing."
+
+"Nothing doing!" Ned repeated.
+
+Collins actually gasped with amazement. He had offered bribes
+before, but had never started out with so large a sum. And he had
+never been denied!
+
+"Understand the proposition," Collins said, presently, as soon as he
+could catch his breath, "it is not you we want. We don't care a
+continental cuss for you. What we want is for you to keep quiet
+after we find Lyman. It is the Secret Service of the United States
+we axe afraid of. I'll make it half a million."
+
+"It must be a rich concession," Ned said.
+
+"It is, and Lyman got it for a song, for no one ever supposed that
+swamp would make good grazing ground."
+
+"I guess Mr. Lyman will earn all he gets out of it," Ned laughed.
+
+"He will never get anything out of it, unless he comes to terms with
+me," Collins said, impatiently. "We'll find some way to keep him
+out of Asuncion until after the 31st. It is a long way from here to
+Paraguay!"
+
+"All the more reason why we should get busy looking for him," Ned
+said.
+
+"And when we find him?" asked Collins, tentatively.
+
+"I shall take him back to Asuncion."
+
+"Then you'd better not find him," threatened Collins. "If you're
+going to oppose me, I'll leave it to you to look him up. I'll go
+back to Asuncion and bring men out here who will see that you never
+leave the mountains."
+
+"Gee! That's a cheerful proposition!" grinned Jimmie.
+
+Collins, disgusted at his failure to either bribe or frighten the
+boys, started away, but Jackson laid a heavy hand on his shoulder
+and swung him around.
+
+"Wait a minute!" he said.
+
+"What do you mean?" demanded Collins.
+
+"You're not going to Asuncion after help," Jackson said. "I have a
+little score to settle with you myself! You're the man who accused
+me of running off cattle. Well, you're going to remain right here
+with me until I go out with you and give you a chance to make that
+right."
+
+Collins glanced at Ned.
+
+"Is this by your order?" he asked.
+
+Ned shook his head.
+
+"I have no present quarrel with you," he said.
+
+Collins started away again, but Jackson thrust him back, not any too
+gently.
+
+"If you make a touse," he said, "I'll tie you up. Now," he added,
+as Collins, almost foaming with rage, threw himself on the ground,
+"I want you to tell me where you left that tent."
+
+Both Ned and Jimmie sprang to their feet at the mention of the word.
+
+"A tent! Here!"
+
+Collins snarled out some impertinent reply, and Ned asked:
+
+"Did they bring in a tent?"
+
+"You bet they did!" Jackson answered. "This fine-haired duck with
+the circus parade clothes wasn't going to sleep in no cavern. He
+was going to have a nice, soft, cool bed under a tent while he was
+waiting for the Lyman concession to lapse. He was reared a pet--he
+was!"
+
+The ex-cowboy was so enraged at Collins for the insinuations he had
+cast upon him that he pushed up to where he lay and would have
+assaulted him if Ned had not interposed.
+
+"Let him alone," the boy said. "We'll leave the law to make payment
+in his case. Are you going to tell us where the tent is, Collins?"
+he added, turning to the angry captive.
+
+"I guess you can get along without the tent," Collins said. "You
+won't have to remain here long. I've got men coming in. They may
+be here at any moment. Officers of the Republic of Paraguay!"
+
+"I shall be glad to meet them!" Ned laughed. "If you'll tell me
+where the tent is I'll be able to entertain them properly."
+
+"Aw, I can find the tent if it is around here anywhere!" Jimmie
+broke in.
+
+"What do you want of it?" demanded Collins
+
+"A little tent cloth," Ned smiled, "would make a serviceable machine
+of the Nelson. We could make new planes in no time. What do you
+think of the idea?"
+
+"I'm not going to have the tent cut up," shouted Collins.
+
+"I guess yes," Jimmie said, provokingly. "You burned our planes,
+and you've got to supply material for new ones."
+
+The little fellow darted away as he spoke, working his way over the
+ledges which separated the two dents on the mountain sides. In a
+short time Ned heard him calling and saw him looking down from the
+shelf above the cavern.
+
+"Come on up," the lad cried. "I can see the tent over in the other
+valley, and there's another automobile coming. What do you think of
+that? This must be a regular station on the underground railroad
+between Asuncion and Lymanville!"
+
+Ned lost no time in gaining the ledge. The white body of the tent
+was in plain sight, just where the men had dropped it out of the
+machine. The two boys hastened into the depression, seized the
+canvas in their arms, and started back toward the Nelson. On the
+shelf again, Ned asked:
+
+"Where did you see a motor car?"
+
+"Over east," was the reply. "There's a tunnel under the range off
+that way. I take it that a river ran there once, draining this
+valley."
+
+Presently the machine appeared in the valley from which the Vixen
+had slipped off into the pit. There were four men in the two seats.
+One was the Indian in goggles who had driven the car away, the
+others were white men. The car could not have gone far, so these
+men must have been picked up just outside.
+
+The boys carried the canvas down to the Nelson and began the work of
+making new planes, keeping close watch, but leaving the newcomers to
+do the calling if there was any to be done. There was plenty of
+canvas and the tools necessary for the work were found in the
+Nelson's tool chest. Collins watched the doings angrily.
+
+"These men," he finally said, "are officers. Two from Paraguay and
+one from Peru. They have warrants for your arrest."
+
+He started to his feet as if to join the others as he spoke, but
+Jackson saw that he did not get very far.
+
+"Tell your friends," Jackson said, "that we're too busy to be
+bothered now. We'll soon have this aeroplane fixed, and then we'll
+give an imitation of men sailing out of this mess. Lyman knows a
+friend is here, for he heard my cowboy call. He will soon come out
+of his hole, and we'll take him back to Asuncion--just to prevent
+international complications!" he added with a grin.
+
+The work of preparing the new planes progressed swiftly, but before
+it was completed the men who had arrived in the automobile appeared
+on the ledge and called down to those below.
+
+
+
+
+CHAPTER XIII
+
+THE NELSON IN THE SKY
+
+
+"Well," Ned called back, as the new arrivals shouted down from the
+ledge, "what do you want?"
+
+"We want to talk with you."
+
+"Cripes," Jimmie grinned, "we're in good demand today. The stock of
+Boy Scouts must be gettin' shy!"
+
+"Go on and talk, then," Ned answered, well satisfied as to what the
+fellows wanted.
+
+"Shall we come down there?"
+
+"You stay away!" Jimmie replied. "We're a little particular about
+our company!"
+
+"Is that little runt speaking for you?" demanded the man on the
+ledge. "If he is, we'll do something besides talk."
+
+"For the present he is," Ned replied. "What can I do for you?"
+
+"You can surrender yourself. We have warrants for your arrest."
+
+"Couldn't think of it!" was the cool reply. "We prefer to remain at
+liberty."
+
+"I told you!" Collins grunted, rising from his reclining position
+and moving toward the ledge. "I told you that you'd get into
+trouble. You'll sweat for this!"
+
+Jackson caught him by the shoulder and whirled him back.
+
+"You stay here!" the ex-cowboy gritted. "The less trouble you make
+the better treatment you will receive."
+
+"What are you doing to Collins?" asked the newcomer. "Tell him to
+come up here."
+
+"I'm being held a prisoner!" Collins shouted. "Train your guns on
+these kids and drive them off. And find Lyman. He left the cavern,
+but he's somewhere about, for he answered a cowboy call not long
+ago."
+
+"We already have Lyman!" was the answer. "He thought we were the
+friends who had called him and joined us. We'll take care of him,
+all right."
+
+"That's fine business--not!" grunted Jimmie.
+
+Ned was not a little disappointed by the announcement. With Lyman
+in the hands of his enemies, it might be impossible to get him back
+to Asuncion in time to save his concession.
+
+And here was another difficulty, one which might bring on a war
+between the United States and Paraguay. Ned, as an official of the
+United States Secret Service, now knew that those high in authority
+in the government of Paraguay were involved in the attempt to
+defraud Lyman of his rights. This had been only suspected before.
+
+So long as only private interests were interfering with the treaty
+rights, so long as the government of the unruly republic was not
+mixed up in the attempt to cheat an American citizen out of his
+property, the government at Washington might well restrain its hand.
+But when the government of Paraguay itself, as Ned now believed, was
+involved in the crooked game, that was an entirely different matter.
+
+Ned believed that a full disclosure of the facts in the case would
+send warships to Asuncion. He believed that an international
+complication might breed open war unless he succeeded in getting
+Lyman away without open conflict with the authorities of the little
+republic. But how?
+
+Well, the State Department at Washington had trusted him, and he
+would do his best. The thing to do at that time, it appeared to
+him, was to await the action of the newcomers. They might be
+officers of Paraguay, with authority to make arrests in Peru, and
+they might be only four-flushers. He must temporize until he found
+out what they proposed to do in the matter.
+
+And, then, he reasoned, if they had Lyman, he had Collins! That was
+not so bad! Perhaps an exchange of prisoners might be made! This
+did not seem very likely, but still there was hope. Collins, for
+all he knew, might be the man who expected to profit by the robbery
+of the American cattleman.
+
+"So Mr. Lyman is there with you?" Ned called back. "Send him over
+here. I want to talk with him."
+
+A harsh laugh was the only answer to this.
+
+"You may as well come to terms with me," Collins exclaimed. "You
+have no chance of winning now. I like your nerve, but you're
+butting into too strong a game for a lad of your years."
+
+"I shall have to take chances," Ned replied. "What will those men
+do with Lyman?"
+
+"I don't know!"
+
+"I know!" Jimmie cried. "They'll kill him!"
+
+"I don't think they'll do that," Collins remarked, with a wicked
+sneer, "but it would clear the atmosphere if he should fall down a
+mountain!"
+
+"If he does," Ned declared, flushing with anger at the brutality of
+the remark, "you will also take a tumble. If he is injured in any
+way, you'll answer to me for it."
+
+"You wait!" warned Collins. "I've handled cases like this before.
+I can give you cards and spades and beat you out. You'll be getting
+hungry before long."
+
+"And the Nelson will be ready for flight before long," Ned replied.
+
+During all this conversation Jackson and Jimmie had kept steadily at
+work sewing the new, strong canvas taken from the tent on the frame
+of the planes. They could not make a very neat job of it, but they
+did their work well. Ned had hope of getting out of the valley that
+very night. Presently the men on the ledge withdrew for a time, and
+Ned began a closer examination of the Nelson. To his disgust he
+discovered that the gasoline was very low in the great tanks. Built
+for long flights, the Nelson's tanks were very large, fitted to
+carry a supply which would last a couple of days. Ned did not quite
+understand why the supply should be short after a run of only three
+or four hundred miles.
+
+"I've got an idea!" Jimmie said, catching the worried look on Ned's
+face.
+
+"I'm afraid it will take something more than an idea to get the
+Nelson back to Lima," Ned replied in a low tone, for he did not care
+to have Collins informed of this new difficulty.
+
+Collins, however, had been watching the movements of the boys
+closely, and at once surmised what the trouble was. He laughed
+insultingly as he pointed to the great tanks.
+
+"Empty?" he snarled. "I knew it. Now will you be good!"
+
+"Shut up!" raged Jackson, who was only too anxious to get a pretext
+for attacking Collins. "We've heard enough from you!"
+
+"'Tie him up!" ordered Ned. "He's likely to make a run for it, and
+then we should have to shoot him. Tie him up good and tight."
+
+"You'll be sorry if you do!" threatened the captive.
+
+Notwithstanding this threat, the fellow was bound hand and foot.
+During the process of the work, which was performed none too gently
+by Jackson, Collins called out to his friends in the other valley,
+but there was no response. They were probably too busy with their
+plotting against the boys to hear the shouts.
+
+This business completed, Jimmie beckoned Ned aside.
+
+"Here's my idea," he said. "The Vixen's tanks didn't blow up when
+she burned and dropped. When it comes night I can go and get the
+gasoline. The tanks were full, were they not?"
+
+"Yes, chock full. The driver seemed to have fitted her out for a
+long run. But we may be able to get the stuff before dark. The
+Vixen did not land in the valley where they are, but in a canyon
+over to the west. Suppose you go over there and see what the
+chances are?"
+
+"All right!" replied the boy. "And if the tanks of the Vixen are
+not full, we'll steal the fuel out of that automobile when it gets
+dark!"
+
+"That's a good idea, too!" laughed Ned.
+
+Jimmie hastened away, keeping in the gully as long as possible and
+dodging around friendly cliffs when it came to climbing over the
+ridge which shut in the valley on the west. The gully cut across
+the valley, east and west, and was very deep at the east end.
+
+After the disappearance of the boy, Ned removed Collins to the deep
+end of the cut and placed Jackson there as a guard. He did not want
+the captive to know what was going on, as a shout to his friends, if
+they again visited the ledge, might put them in possession of the
+facts regarding the empty tanks of the Nelson. Then it would be an
+easy matter for them to prevent the getting of the gasoline from the
+wrecked Vixen.
+
+Then Ned, hearing no more from the alleged officers, went to work on
+the planes, and succeeded in getting a long strip sewed in before
+Jimmie returned with his report.
+
+"The tanks are almost full," the lad said, "and all we've got to do
+is to unscrew a couple of burrs and lug them right over here. We
+can't do that until, after dark, for they would shoot at us.
+Where's Collins?"
+
+Ned pointed to the gully.
+
+"Well," the boy continued, "when I got up on that ridge, I could see
+the men over in the other valley. They are getting reinforcements
+from somewhere. Anyway, I saw half a dozen Indians standing around.
+They've got a fire and are cooking dinner. Then I saw one of the
+white men pointing, and I'll tell you right now what they're going
+to do! They're going to station men around this little old crater
+and keep us in here until we starve, unless we give in."
+
+"They forget that there's an air route," laughed Ned.
+
+"Suppose we get up there on the Nelson!" exclaimed the boy. "And
+suppose they shoot us off! That wouldn't be funny, would it?"
+
+"We've got to go in the night, then," Ned said. "But before we go I
+want to have a talk with those fellows."
+
+"Then you'll get a word with Lyman, if you can?"
+
+"That wasn't a bluff, then? They have captured him again?"
+
+"Oh, yes, they've got him with them, all right. Anyway, there's
+four white men, and only three came in the car. Guess it's Lyman,
+sure enough!"
+
+"What is he doing?"
+
+"Just walking about. They haven't got him tied up, at least the man
+I took for Lyman isn't. He looks mad enough to bite nails, though!"
+
+"That is a wonder," Ned said. "It may be that they are trying to
+make terms with him."
+
+"Of course!" replied the boy.
+
+Along in the afternoon one of the alleged officers appeared on the
+ledge again. He appeared to be somewhat excited, and Ned suspected
+that something had gone wrong with the other party. However, he
+remained quiet, waiting for the other to make his errand known.
+After a short silence the fellow asked:
+
+"What has become of Collins?"
+
+"He is still here," Ned answered.
+
+"Held against his will?"
+
+"Well, he is still doing some kicking."
+
+"You'll be sorry if you don't let him go."
+
+"How will you trade prisoners?" asked Ned. "Send Lyman down here
+and we'll send Collins up to you."
+
+"Oh, Lyman doesn't want to leave us," was the reply. "We've
+arranged a settlement with him."
+
+Ned did not believe this. He knew that the Lyman concession was a
+valuable one, and that the cattleman would put up a long fight
+before sacrificing it.
+
+"Send him down here then," Ned answered. "If he is voluntarily
+staying with you, he can return if he wants to. Send him down!"
+
+"He is afraid you'll try some trick on him," was the reply.
+
+The whole afternoon passed in just such conversation as this--talk
+which brought no results worth mentioning. Ned did not believe that
+Lyman was remaining with the newcomers voluntarily. He did not
+believe that Lyman was suspicious of him.
+
+The men in the other valley frequently visited the ledge and talked
+with Ned, but the boy saw that they were quietly making arrangements
+to surround him. Now and then the figure of an Indian appeared on
+the elevations about the valley, which was the crater of an extinct
+volcano.
+
+A little study showed Ned that in some long forgotten time the two
+valleys had formed a great crater, and that this had been cut in two
+by the elevation of a mass in the center. High up above this dead
+crater, on the north, stretched the bulk of the mountain, the
+eruption having taken place on its south slope.
+
+But while Ned talked with the visitors, argued with them,
+threatened, he kept at work on the planes, and at nightfall had them
+completed. The canvas had been put on double and sewed on very
+strongly, so the boy believed that it was as good a machine as ever
+that he contemplated getting out that night.
+
+"But," argued Jimmie, when the plans were laid, "we can't all go in
+the Nelson. How are you going to carry Lyman, Jackson and me?"
+
+Jimmie thought for a moment and then added: "But we haven't got
+Lyman yet. We'll have to come back after him, I take it, after we
+land Jackson outside."
+
+"But I'm going to get him," Ned replied, "if this machine works all
+right. I'm going to leave you and Jackson here. What about that?"
+
+"If you can grab Lyman," Jimmie grinned in disbelief, "I'll be
+willing to stay here as long as the grub lasts!"
+
+"I'm going to get him," Ned replied. "I don't know how, but I've
+just got to get him back to Asuncion before the 31st."
+
+"And what about Collins?"
+
+"We'll have to let him go. When I get out, let him go, and then you
+two will have to hide away until I can come back after you."
+
+"All right," replied Jimmie, with a sigh. "Only hurry back! I
+don't want to starve to death here."
+
+After dark Ned, Jackson and Jimmie lugged the tanks of the wrecked
+Vixen over to the valley and dumped the gasoline into the Nelson's
+tanks. Even this accession did not quite fill the latter.
+
+"Wish we could get to the motor car," Jimmie suggested.
+
+"Now," Ned said, "I want you two to kick up an awful rumpus here,
+directly. Shoot and do all the yelling possible. Let Collins loose
+and chase him! He deserves it! Then, when the fellows over there
+run up on the ledge to see what is doing, I'll swoop down in the
+aeroplane and pick up Lyman--that is, if he is willing to come with
+me. If he isn't, I can't get him, that's all."
+
+"Then, when we get up in the air, we take to our heels?"
+
+"Exactly. If you don't these fellows will make trouble for you.
+Hide, but keep making to the east. When I come back after you I'll
+come in from that way."
+
+"How long will it be?" asked the lad, who did not quite like the
+notion of being left there with Jackson.
+
+"I can't say," was the reply. "I may leave Lyman in the nearest
+town, or he may want to go to Asuncion. I may be back by daylight,
+and I may be gone two days. I hope to be back by daylight."
+
+"All right," Jimmie grunted. "We'll keep off to the east, and when
+you return you can pick us up before they know what's going on.
+Here's hoping you get Lyman!"
+
+"I'll get him!" Ned replied, shutting his teeth hard together.
+
+So, all arrangements made, Jimmie crept up on the ledge, about nine
+o'clock, and looked over into the twin valley.
+
+There was a campfire burning, and Lyman, or the man the boy took for
+the cattleman, sat close beside it. The others were walking about.
+Now and then an Indian stepped inside the circle of light cast by
+the fire, consulted with the others for a moment, and disappeared
+again.
+
+It was certain that the alleged officers were preparing to advance
+on the boys, bent on putting the Nelson out of commission for good.
+The planes had not been repaired any too quickly. When Jimmie
+reported Ned stepped into the machine.
+
+"When I get within sight of those in that valley," he said, "make
+all the noise you can. If you can cause them to think you're
+killing Collins, all the better. Make him yell! I'll go straight
+up and drop down by that fire before they get over their
+excitement."
+
+A few strong shoves, a dozen revolutions of the rubber-tired wheels,
+and the Nelson left the ground, as strong and capable as ever. The
+motors made little noise, and no signs of discovery came from the
+other side until the machine was high up. Then a few ineffectual
+shots were fired at her.
+
+Jimmie and Jackson began their part of the performance promptly by
+shooting and yelling. They loosened Collins, much to that
+gentleman's delight, and started him off in the dim light on a run.
+As Jackson took great delight in landing his bullets close to
+Collins' feet, the alleged salesman ran for dear life toward the
+ledge, screaming and calling for help at every jump.
+
+This was exactly what the others wanted, and in a short time they
+saw a huddle of dark figures on the ledge. In the excitement the
+firing on the Nelson had ceased.
+
+Jackson and Jimmie were not long in getting out of the valley after
+that. They whirled around the elevation between the two valleys,
+sometimes feeling their way in the darkness, climbed over a ledge,
+and made for the black entrance to the tunnel through which Jackson
+had entered.
+
+When they were at the mouth of the tunnel they turned and looked
+back. The Nelson was lifting from the valley where the fire had
+been seen, whirling up, up into the night sky. They could not
+determine from where they stood whether there were two or one on the
+big aeroplane. They had no means of knowing whether Ned had
+succeeded or failed.
+
+The two watched the dim bulk of the aeroplane as it winged over
+their heads. Now and then, after it was too late to do her any
+harm, a few vengeful shots were fired at her. The fact that Ned
+kept going convinced them that he had picked up Lyman and was on the
+way out with him.
+
+After the aeroplane had disappeared from sight Jackson and Jimmie
+hurried on through the dark tunnel, which, as has been said, was
+merely the dry channel of a stream which had cut its way out of the
+valley years before. Jimmie proposed that they remain there all
+night, but Jackson objected to this.
+
+Their pursuers knew that he knew of the tunnel, he explained, in
+support of his objection, as they were aware that he had entered the
+valley by that route, so they would naturally look there for them.
+
+This was convincing, of course, and the two hastened on their way,
+lighted by the little searchlight. For a long time there were no
+indications of pursuit, then a popping roar came beating down the
+passage.
+
+"That's the automobile!" Jimmie cried. "Sounds like an express
+train, eh?"
+
+"It certainly does," Jackson replied, "and it is up to us to get out
+of the way, somewhere. They won't take extra pains to catch us
+alive."
+
+
+
+
+CHAPTER XIV
+
+ARRESTED FOR SMUGGLING
+
+
+The Nelson swept out of the air like a bird and landed so close to
+the fire that Ned felt the warmth of it on his face. The wheels cut
+the earth at first, under the force of the quick descent, then
+stopped.
+
+The firelight shone on the white planes, bringing them out strongly
+against the darkness, and Ned knew that he could not remain there a
+minute without being discovered by the alleged officers of the
+little republic he was just then warring against. When he landed
+the men were out of sight around the ledge, but they of course saw
+the aeroplane and came running back.
+
+Lyman, or a man Ned believed to be the cattleman whose financial
+operations had stirred up an international row, stood moodily by the
+fire when the Nelson dropped down, almost on top of his head. He
+sprang away, rubbed his eyes as if trying to awake himself from a
+bad dream, and then stood stock still, watching.
+
+"Lyman?" Ned called.
+
+There was no reply, and Ned spoke the name again.
+
+"Yes, Lyman," the man by the fire answered, then. "What new wrinkle
+is this?" he added, stepping a little closer to the machine.
+
+"If you're Lyman," Ned replied, hastily, "you can't get in here any
+too quickly. Those fellows will be here directly, with Thomas Q.
+Collins in the lead, if my boys do their duty. There will be little
+chance for either of us then. Jump in!"
+
+"But I've never been on one of those things, and I'm afraid," Lyman
+said, with a shrug of the shoulders. "I'm afraid I'd fall out."
+
+A shot came from the ledge, and Ned reached for the button which
+would start the motors going.
+
+"You've only a minute to decide," he said. "I've come a long way to
+find you. If you reject this chance you won't get another."
+
+"Well," Lyman cried, stepping up to the seat, very shaky as to
+nerves and pale as death, "I may as well die from a fall as from a
+bullet or a knife. If Collins is coming back with the officers,
+I'll have to do something."
+
+The instant he was in his seat, Ned threw the leather straps about
+his legs and wrists and buckled them tight. Lyman shivered with
+fright.
+
+"I thought so!" he cried, mistaking Ned's motives. "This is only
+another trick!"
+
+The wheels bumped for an instant over the inequalities of the
+surface, the machine rocked lightly, then the planes lifted into the
+air, the propellers running like mad. A few ineffectual shots came
+from the men who were running down from the ledge. Ned saw Jimmie
+and Jackson chasing Collins out of the valley, heard their shots,
+and then, in a few moments, saw them at the mouth of the tunnel.
+
+In five minutes more the Nelson was out of all danger, purring
+through the darkness like a contented cat. Lyman sat moodily in his
+harness, saying not a word, but fully convinced that this was only
+another trick of his enemies. Directly the boy slowed the motors
+down so as to make conversation possible.
+
+"Well," he said, turning on one of the electric bulbs so as to see
+the face of his passenger, "what do you think of the Nelson? Peach,
+isn't she?"
+
+"Where are you taking me?" was the only reply to the question.
+
+"That is for you to say. We are not very far from Sicuani, Peru,
+and from there you can secure transportation back to Asuncion--if
+you think it safe to go there, under the circumstances. About a
+hundred miles to the north is Cuzco. You can go there and prepare
+for your visit to Asuncion if you care to. Then, over here in
+Bolivia, is Sucre. It might be well for you to go there. Anyway,
+it is up to you."
+
+"Who is doing this?" asked Lyman, suspiciously.
+
+"I can't see as that makes any difference to you," Ned replied.
+
+"I was in the hope," Lyman went on, "when you came down upon me so
+unexpectedly, that my friends had found me. You speak English like
+a New York man," he went on. "Perhaps you live over there?"
+
+"Yes," was the reply. "I live in New York, when I am home."
+
+"Nice little old rotten government we've got!" almost shouted Lyman.
+"The people at Washington let any crooked little republic do
+anything it has a mind to do to a citizen of the United States.
+They're too busy getting themselves into office and keeping in to
+pay any attention to their duties. England wouldn't stand for a
+minute the tricks that have been played on me, not by business
+rivals, but by the government of Paraguay! England protects her
+citizens, wherever they are!"
+
+"Well," Ned replied, with a laugh, "you may be right about England,
+but you are wrong about Uncle Sam. He looks after his own, too; if
+he didn't I wouldn't be here now. You wouldn't be on earth!"
+
+"Do you mean to say--"
+
+Lyman hesitated, and Ned went on and told him as much of the history
+of the expedition as he thought it necessary for the cattleman to
+know.
+
+"And now," he concluded, "Where do you want to go?"
+
+"I want you to go with me, wherever I go," was the reply. "And I
+think we'd better go straight to Asuncion."
+
+"Do you think that a safe plan?"
+
+"Oh, yes; they won't dare abduct me again."
+
+"Then," Ned added, "we may as well get on the way. Asuncion is
+somewhere about twelve hundred miles from here, and we've got to
+make it by daylight."
+
+"What's that?" asked Lyman, hardly believing he had heard aright.
+"You would better say in two days."
+
+"The Nelson can make it in eight hours," Ned replied, "if we don't
+drop into any holes in the air or adverse currents."
+
+"Holes in the air!" repeated Lyman.
+
+"Sure," answered Ned. "The atmosphere surrounding the earth is just
+like the water in the large reservoirs--there are deep places and
+shallow places, holes you can drop in, and currents like the Gulf
+Stream current, the Japanese current, which warms the northern
+states and British Columbia, and the Arctic Humboldt current, which
+sends a cold stream down the Pacific coast of South America. If we
+have no difficulties with these rivers of the air, and the wind does
+not come up too strong, we can make Asuncion by six o'clock in the
+morning. It is about ten now."
+
+"What sort of an airship have you here?" demanded Lyman, amazed at
+the thought of running at the rate of two hundred miles an hour or a
+hundred and fifty, at least.
+
+"She was built for speed and endurance," was the reply. "Now cover
+your face with this mask, unless you want to have your breath blown
+out of the back of your head, and we'll get under way."
+
+That was a night ride which neither of the participants ever forgot.
+The first part of the night was dark. Then a moon shone down from a
+cloudless sky, showing all the beauties of that magnificent country.
+
+The mountains, the forests, the headwaters of the rivers which help
+to make the Amazon, were under their feet. Now and then they swept
+over a point of light which denoted the presence of a small town.
+Occasionally the cry of frightened wild beasts--the vicious mountain
+lion, the savage tiger cat, the prowling puma--came up to their
+ears.
+
+After a short run to the southeast, Ned wheeled about and struck
+straight off to the east. The wind was growing stronger, and the
+Nelson was not making as good time as the boy desired.
+
+There was a fierce current about the top of Mt. Sorata, which is
+something over 21,000 feet in height, and again Ned swung off to the
+north. Dropping down, then, he swept into the valley of the Beni
+river, which joins the Madeira river, some distance beyond the
+Bolivian border.
+
+He knew that at the eastern rim of Bolivia there was a series of
+high mountain ranges which would protect him from the drifts blowing
+over from the Atlantic--Serre Geral, Serre Paxecis, Serre
+Aguapehy--and he reasoned that he could make better speed under the
+lee of these elevations. So he swept down the valley of the Beni
+until it joined with the Madeira, crossed a line of hills, and made
+for the Serre Geral range, something under a hundred miles away.
+
+As the Nelson cleared the valley, however, Lyman gave Ned a punch in
+the ribs with an elbow and nodded toward the ground. His wrists
+were fast in the harness so he could not use his hands. Ned looked
+down and instantly dropped the Nelson a few hundred feet.
+
+Some distance down the Madeira, in the center of the stream, were
+the lights of a boat which seemed to be anchored there. Ned swept
+closer and tried his best to make out the outlines of the craft, but
+he could not do it without descending close to the river, and this
+he did not care to do.
+
+"It looks like the Black Bear," he thought, as he shot up into the
+air again, "but of coarse it can't be. Those Boy Scouts are not
+fools enough to bring her up into this country."
+
+So he came to the protection of the mountains and proceeded south
+toward Asuncion at a speed which caused Lyman to gasp for breath.
+Of course he was ignorant of the fact that Frank, Jack, and Harry
+had started out, during his absence, to explore the headwaters of
+the Amazon, hoping to come upon the Nelson before returning.
+
+As for the lads on the Black Bear, they did not even know that the
+Nelson was so close to them that night. It was three nights later
+that they first saw the aeroplane drifting above them. Asuncion
+does not at all compare in beauty or in thrift with the other
+capital cities of South America. The government of the republic is
+so unstable that business men are loath to make heavy investments
+there.
+
+For one thing the town is poorly lighted, and when Ned came, in view
+of the place at five O'clock the few street lamps were already out.
+People were abroad at that early hour, however, and small crowds
+soon gathered on the street corners to watch the great airship
+approach.
+
+What Ned could not see was the intense excitement around the
+government offices. In ten minutes from the time the airship showed
+above the city, messengers were out in the streets and officials of
+the lower rank were headed for their offices. In a few minutes this
+alarm was communicated to police headquarters and to the military
+station where the governor's guard was stationed.
+
+If the boy had been able to understand the situation below, if he
+had known that Asuncion had been communicated with from Lima and
+also from Sicuani, he would have given the city a wide berth. He
+saw the gathering of crowds below, of course, but naturally
+attributed this to curiosity. He had no doubt that the Nelson was
+the first airship ever seen at Asuncion.
+
+"Where are you going to take me?" asked Lyman, as the machine slowed
+down and he found himself able to speak.
+
+"To the American consul," was the reply.
+
+Lyman sighed and shook his head.
+
+"I'm afraid he will take little interest in me," he said.
+
+"Doubtless," Ned replied, "he has received instructions from
+Washington. Anyway, I fail to see how they can molest you now, even
+if they have the inclination to do so. You just go about your
+business as usual, and leave this abduction matter to the future.
+You can gain nothing now by stirring that up. Report to the consul
+and go on about your business as if nothing had happened."
+
+"That is the only thing there is to do," Lyman responded, with a
+sigh. "Still, I'm suspicious of those chaps. They'll have some
+trick ready."
+
+Before long Ned found a level spot not far from the capitol building
+where he could, drop the Nelson. When he headed for that locality
+he was followed through the streets below by a shouting, howling
+mob.
+
+"I can't understand this," he thought, and Lyman was still more
+suspicious.
+
+At last the Nelson was brought to the surface of the earth and Ned
+and Lyman stepped out, very willing to stretch their legs after such
+a long ride. They had been in the air about twice the time set for
+endurance by noted aviators.
+
+They did not get much of a chance to stretch their legs, however,
+for they bumped into a squad of soldiers on stepping out of their
+seats.
+
+"You are under arrest!" a gaily-dressed officer said, flashing his
+sword out of its scabbard.
+
+"What for?" demanded Ned, speaking in Spanish.
+
+"Smuggling!" was the reply.
+
+Ned laughed heartily. Arrested for smuggling!
+
+"Search us, and search the machine, then," he replied, "and let us
+go on about our business. We have no time to lose."
+
+"In time! In time!" was the drawling reply. "Such things are not
+done so quickly here! In three-four days--in a week--in three, four
+weeks, perhaps. In the meantime you go to the jail."
+
+Ned thought of the swiftly-slipping days, of the peril Jimmie and
+Jackson were in, of Leroy in prison at Lima, and was about ready to
+fight. The officer refused to take him to the president, or to the
+American consul. In a quarter of an hour he was in a cell, alone,
+wondering what had been done with Lyman, and also wondering what
+would become of the Nelson.
+
+He knew that the charge of smuggling, of bringing goods into the
+republic by means of an airship, would be held against him as long
+as it pleased his accusers to keep him in prison. That would be
+until the concession expired and, possibly, until the Nelson lay a
+total wreck in the streets.
+
+He saw no one who could give him any information as to what was
+going on in the outside until the morning of the 21st, after he had
+been incarcerated forty-eight hours. Then a turnkey unlocked his
+door and motioned him out.
+
+"For trial?" Ned asked, hopefully.
+
+"It is the wish of the president," was the reply.
+
+"But what, why, when--"
+
+"You have yet to see," was the impertinent reply. "You have yet to
+see if you can do these things to our countree!"
+
+And so, mystified and, if the truth must be told, not a little
+discouraged, Ned was led through the prison corridors, his mind
+filled wit thoughts of Leroy, Jimmie, the Nelson, and, strangely
+enough, the Black Bear!
+
+
+
+
+
+CHAPTER XV
+
+THE WARNING FROM THE SKY
+
+
+There was a shock when the prow of the Black Bear struck a canoe
+which lay full in its path. The momentum was retarded for only a
+second. Then the motor boat was beyond the line of war canoes with
+their screaming, gesticulating occupants.
+
+Looking out of the rear ventilator, Frank saw a smashed canoe
+running down with the current, with a dozen or more natives clinging
+to it. But there was still a large number of canoes up the river,
+and the Black Bear was struck more than once by forceless bullets
+and poisoned arrows as she sped past them.
+
+Armed with modern rifles, the Indians would have made short work of
+the occupants of the Black Bear, but the muskets they used were old
+and mostly out of condition. The arrows were far more deadly,
+although they stood less chance of penetrating the tough panels.
+
+"Now," Harry said, as they passed a racing fleet of Indian boats,
+"we can open up a little and get a breath of fresh air! I'm just
+about suffocated!"
+
+"Not just yet," Jack, who was at the front, said, "for there's a
+mess of the black scamps just ahead. They are on the bank, both
+banks, and seem to be waiting for something to happen. I wonder
+what it can be?"
+
+"Some trap, I suppose," Harry gritted. "Well, all we can do is to
+ran on through them, if they come out in boats, and get out of their
+reach. We ought to be able to be out of this blasted country in a
+couple of hours."
+
+"That's all right," Jack replied, "but you just listen a moment."
+
+But the racing motors shut out all individual sounds, and Harry shut
+them down for a minute. Seeing this, Jack dropped an anchor at the
+prow, and the boat lay pulling at the cable in the current.
+
+"What did you do that for?" asked Frank, addressing both boys from
+the stem.
+
+"Listen!" commanded Jack.
+
+"Look!" ordered Harry.
+
+What Frank heard was the heavy, continuous roar of a waterfall.
+What he saw, as he crowded up under the plate glass panel in the
+top, were the lights of an airship!
+
+"I tell you," Harry cried, excitedly, "that that's the Nelson. You
+can't fool me about that."
+
+"Why doesn't she come down, then?" demanded Jack.
+
+"Because she doesn't know that this is the Black Bear. That is an
+easy one! If she did she'd be here in a second."
+
+The boys studied the lights a moment and then turned their attention
+to the Indians, who were now making a great clamor. In a short time
+it was easy to see what they were up to.
+
+Above roared the falls and the rapids. At this point in the Beni
+river there is a swift drop from the mountain plateau above. It
+will be remembered that the Beni reaches away up into the Illimani
+mountains, with its springs not far distant from the summit of the
+Andes.
+
+Where the boys were the Paredon and the Paderneira, falls and the
+Araras and the Misericordia rapids made the navigation of the river,
+even in the protected Black Bear, impossible for many miles. The
+Indians seemed to understand this, for they had gathered at the foot
+of the falls, possibly expecting to see the craft attempt the
+ascent.
+
+Jack watched them from the prow for a time and then asked:
+
+"What's that they are throwing into the river?"
+
+"Logs!" replied Harry, looking out over Jack's shoulder, "and
+brush!"
+
+"Well, of all the--"
+
+The sentence was not finished. Frank, at the stern, gave a yell and
+fired out of the loophole. "Come here!" he shouted, then, "if you
+want to see what the devils are doing. This takes the cake!"
+
+A glance showed the others what the plot against them was. Harry
+went to his locker for his revolver and Jack drew his from a pocket.
+
+"I guess it is a fight now!" Frank said. "You see what they are
+doing?"
+
+"Of course. Anybody can see that."
+
+Jack reached out of the opening and fired a perfect volley down
+stream. Frank crowded against him to look out.
+
+"Never touched them!" he cried.
+
+"No," Jack went on, "they're forming a bridge with their canoes and
+running logs and brush down against it. They've got an obstruction
+already that the Black Bear never can get through."
+
+"What's the matter with dynamite?" asked Harry.
+
+"Oh, we can use dynamite as long as we have it," was the reply, "but
+there will be Indians on guard there long after we are out of the
+stuff."
+
+"I guess that's right!" with a sober drawing of the lips.
+
+"I'll tell you what we've got to do," Harry said, presently. "We've
+got to put on full power and try to run up the rapids."
+
+"Why, there is noise enough for a ten-foot fall," Frank replied.
+
+"We've got to risk it," Jack went on.
+
+"Now, you just wait," Frank cut in. "I don't think you've got this
+thing sized up right at all. Harry," he continued, "who does this
+boat belong to?"
+
+"To the Black Bear Patrol," was the reply. "You know that well
+enough."
+
+"Then we can do what we please with it, so long as we make it right
+with the other members of the Patrol?"
+
+"Why, of course."
+
+Jack looked at his chums with a grin.
+
+"What are you figuring on?" he asked. "One would think you were
+planning to blow the Black Bear into smithereens."
+
+"That's about it," Frank replied.
+
+"And go to kingdom come with her?" laughed Jack. "Not any of that
+for me. I'm headed, eventually, for little old N.Y."
+
+"I'm tired of fooling with these cannibals," Frank explained. "We
+haven't molested them, and yet they are after our scalps. They'll
+get them, too, if something isn't done--and done right away, at
+that."
+
+"I'm with you!" Jack exclaimed. "I'm willing to try anything once.
+Only let me in on the secret!" he added, chuckling.
+
+ "You had it right," Frank said. "What I propose is to blow the
+Black Bear into smithereens, and about a thousand of those
+bloodthirsty natives with it. The world will be all the better for
+their being out of it. They are worse than the savage beasts in the
+forests."
+
+"But what is to become of us?" asked Harry.
+
+Frank pointed to the Wolf, tugging at the cable which held her nose
+to the stem of the Black Bear.
+
+"We'll be safe in there when the explosion takes place," he said.
+
+Jack clapped the speaker on the shoulder.
+
+"You're all right!" he cried.
+
+Harry looked mystified for a moment, and then said, speaking loudly
+in order that his voice might be heard above the shouts of the
+savages and the beating of arrows against the panels of the boat:
+
+"It looks as if we'd have to do it. I hate to leave the Black Bear
+in such a mess away off here in South America, but I don't see how
+we are to get her out. The Wolf will carry us all right, I
+suppose?" he said, tentatively.
+
+"Sure thing!" Frank replied. "I've been thinking it all out. We'll
+do it this way: When we get ready we'll put on full speed ahead on
+the motors, with the prow turned against that obstruction below.
+Then we'll hop into the Wolf and shut everything down tight. The
+Black Bear will weaken the jam below, and the sharp nose of the Wolf
+will poke through the rest of the logs and canoes. And there you
+are!"
+
+"Free of the natives, and bobbing down the river in safety!" cried
+Jack. "That looks good to me!"
+
+"But about the dynamite?" asked Harry.
+
+"Well," Frank replied, "we've got to use the Black Bear for a
+battering ram anyway, and she'll be all smashed up, so we may as
+well go the whole hog with her. We'll put a lot of dynamite down
+under the motors and fix a cap so it will blow up when the
+concussion comes. By that time the natives will be swarming around
+her, and they'll get what's coming to them."
+
+"And where will we be when the explosion is rocking this half of the
+world?" demanded Harry. "Up in the air?"
+
+"We'll be a cuddled up in the Wolf, between the lockers, with plenty
+of grub and ammunition, sailing down the river in a bullet-proof
+vessel. This move will burst up our meeting with the Nelson, of
+course, but there is no other way. They'll get us if we remain
+here."
+
+While this talk had been going on, the cannibals had drawn nearer to
+the Black Bear, pressing forward from both banks in canoes and
+pounding at the panels with their arrows. It seemed only a question
+of time when they would board the craft and force the panels. Their
+shouts of victory were shrill and exasperating.
+
+"You see how it is," Frank said, "the Black Bear can never be pushed
+up over the falls, and we can never get her past the obstructions
+below, even by the use of dynamite. If we could blow the those logs
+out of the way, the Indians would board us instantly. We could give
+them only a charge or two of dynamite and a few shots before they
+would be inside. Now' we can drift down the river in the Wolf
+without fear of entertaining man-eaters on board. They may get on
+top of the boat, but they can never get inside."
+
+"And so we'll have to give up our trip!" wailed Harry. "We'll have
+to drift down stream in that hot hole and take a steamer at the
+nearest river town!"
+
+"It strikes me," Frank observed, "that it is a mighty good thing
+we've got that hot hole to drift down stream in. If the Black Bear
+had only been constructed on the principle of the Wolf, we'd be in a
+position to give these heathens the laugh. Well, let us pull the
+Wolf up and throw out stuff enough to give us room. Then we'll get
+out the dynamite."
+
+The boys drew the Wolf up by the cable as Frank tried to elude the
+watchful eyes of the savages long enough to open the hatch on top
+and climb inside, but a dozen arrows whizzed by his head when he
+looked out.
+
+"Can't do it!" he said.
+
+"Never in the world!" Jack assented.
+
+"Another good scheme gone wrong!" Harry ejaculated. "What next?"
+
+"Dynamite," almost shouted Jack. "We'll give them dynamite as long
+as it lasts, and then ram the logs below."
+
+"We may kill, a couple of hundred," Frank said, "but it seems to me
+that there will be about ten thousand left."
+
+The boys were indeed in a tight box. With their automatics and
+their dynamite they might keep the natives at bay for a time, but in
+the end they would be obliged to surrender or starve to death.
+
+"Well," Jack said, grimly, "let's get out the dynamite. I want to
+see some of these devils blown up!"
+
+Just then an arrow struck the plate glass panel at the top of the
+Black Bear's deck covering and Jack looked up. He gazed a moment in
+wonder and then let out a shout that rose above the yelling of the
+savages and the pounding of arrows against the panels of the Black
+Bear.
+
+"Glory be!" he shouted.
+
+Frank and Harry crowded to his side and looked up.
+
+"It is the Nelson!" Harry exclaimed.
+
+"You bet it is!" Frank admitted.
+
+"Good old Ned!" Jack roared.
+
+The aeroplane was only a few yards above the Black Bear. Already
+the natives were slinking away in their canoes. Those on the banks
+were slowly withdrawing into the shelter of the forests.
+
+"They're running away!" Jack cried. "Now we'll have some fun with
+good old Ned Nestor!"
+
+For a moment it looked as if the statement was correct; as if the
+natives, alarmed at the sight of the aeroplane would disappear from
+sight without a fight. But this supposition was soon disproved.
+
+As the Nelson came nearer, a dozen bullets from the forests struck
+her planes. The boys, in the boat raised the panel and shouted to
+the aviator to look out for poisoned arrows.
+
+Then the aeroplane shot up again. They could see that there was
+only one person on the machine, and that he was busy arranging
+something which looked like a stick of dynamite which he held in his
+hands.
+
+In a moment something grim and sinister whirled and hissed through
+the air, and then there came a terrific explosion in the forest to
+the right. Trees were leveled, and a great hole showed in the bank.
+In an instant, following close on the roar of the dynamite, there
+came a chorus of cries from savage throats-cries of fear, of terror,
+of rage--and then silence.
+
+For a moment it seemed as if the forests held no forms of animal
+life, then the sharp call of the tiger-cat, the wail of the puma,
+the chattering of the monkeys, came to the ears of the listening
+boys.
+
+"I guess this coming act will consist of a feed for the wild
+beasts!" Jack said.
+
+For a long time there was no sound of savage life in the forests,
+save that from the throats of beasts of prey, scenting blood and
+slowly drawing closer to the river's banks. The boys on the Black
+Bear looked into each other's faces and wondered.
+
+"They didn't act that way when we exploded dynamite!" Jack said.
+
+"No. They came right back at us!" Frank replied.
+
+"I take it that they think there's something supernatural in this
+dropping of dynamite from the sky," Harry observed. "Anyway, they
+seem to have taken themselves off, and we'll open up and signal to
+the Nelson! Say, won't it be fine to see good old Ned Nestor again?
+I wonder how he knew we were here?"
+
+"And I wonder where Jimmie and Leroy are?" Harry reflected. "There
+is only one person on the machine, and that must be Ned."
+
+Jack was about to throw open the top panels when he caught sight of
+the aeroplane again, nearer to the water than before.
+
+"What's Ned doing?" he asked, pointing upward.
+
+"Talking!" exclaimed Frank.
+
+"Wigwagging!" Harry broke out. "Now, let us see what he says."
+
+Slowly to the right and left, up and down, an electric bulb flashed
+in the sky. Harry counted.
+
+"That's C;" he said, "and that's 'a,' and that's 'u,' and that's
+'t,' and now 'i,' and 'o,' and 'n.' 'Caution!' That means that
+we've got to stand pat for a time yet."
+
+"It also means," Jack said, "that we've made no mistake about that
+being the Nelson, with a Boy Scout on board. Those wigwag signals
+show the supposition to be true."
+
+"Well," Harry puzzled, "he wouldn't be sending us a warning from the
+sky if there wasn't some danger we were not aware of. There is
+something going on that we are not wise to."
+
+There was a short silence on board and then Frank remarked:
+
+"We must be nearer the falls than we thought, for the water seems to
+be a ripple about us. Rear it! I'm going to look out and see it
+looks like."
+
+In a moment he was jamming the panel shut and springing the slides
+over the loopholes and the ventilators.
+
+Jack sprang to the prow, not knowing what danger threatened, but
+obeying the sudden gestures of his chum to close every opening.
+Before he sprung the steel panel over the ventilator he glanced
+out on the river.
+
+"Great heavens!" he cried. "Get your guns, boys!"
+
+The whole surface of the stream, as far as the boy's eyes reached,
+seemed covered with savage heads, floating, drifting, down upon the
+Black Bear.
+
+
+
+
+CHAPTER XVI
+
+RED FIRE FROM THE SKY
+
+
+Under the light of the moon the rushing river seemed full of
+leering, cruel eyes. The bodies of the swimming savages were not
+visible--only the upturned faces and the threatening eyes, with now
+and then a hand or the point of a glistening shoulder. There
+appeared to be thousands of the cannibals; their mass reaching from
+shore to shore.
+
+Then, while the boys looked, expecting every instant to hear the
+sound of feet outside the panels, a rocket shot out from the Nelson
+and a score of parti-colored balls curved and hissed toward the
+earth.
+
+"Gee!" Jack cried. "He's giving them a fourth-of-July celebration!"
+
+"Hope it scares them off," said Harry.
+
+Looking through the heavy glass panel at the top, they saw a rain of
+red fire drop down on the swirling river. For a moment the whole
+upper air, then river and forest, was painted a bloody red by the
+burning powder.
+
+Cries came from the river, and the mass of floating heads parted and
+swung swiftly toward the shores; then silence. The aeroplane
+circled about cautiously and then dropped down lower. Jack opened
+the panel.
+
+"Hello the boat!" cried a voice from the aviator's seat.
+
+"Hello, Ned!" all three boys called back.
+
+"How do you know it's Ned?" was asked.
+
+"We saw that beautiful face of yours in the red fire," replied Jack.
+"How are we going to get out of here? They've blockaded the river
+below, and the falls are above."
+
+"I presume I have dynamite enough to blow up that improvised dam,"
+replied Ned. "Why didn't you do it?"
+
+Before Jack could explain the situation, the Nelson drifted past,
+and he knew that his voice would not carry to her.
+
+"I'm going to open up now," Harry said, as the Nelson drifted out of
+range of the glass pane. "I'm pretty near choked in here."
+
+"Nice time we would have had in the Wolf," laughed Jack.
+
+"Anyway," urged Harry, "we should have been in her in a minute if
+the Nelson hadn't shown up. Say, won't they give us the laugh in
+New York? Came away off out here alone, and then had to be rescued
+by Ned!"
+
+ Very cautiously the panels giving on the stern were opened. There
+were no savages in view. The banks of the stream seemed as quiet
+and harmless as a thicket in Central Park.
+
+"I guess the rocket and the red fire got them!" grinned Frank.
+
+"Yes, but they won't stay scared forever!" Harry put in. "We'd
+better be getting out of this before they come back to their
+senses."
+
+"They never had any senses!" claimed Jack.
+
+Looking out from the interior, now guarded only by the panels at the
+front and sides, the boys saw Ned drop half a dozen sticks of
+dynamite on the logs and brush which had been floated down on top of
+a number of canoes. In some places the logs had pushed up until
+they were high above the surface of the water.
+
+The pressure of the current was continually making the obstruction
+more compact. The canoes seemed to have been bound firmly together
+and stretched from shore to shore. At least the moorings were
+strong, for the logs were heavy and the current pulled heavily at
+them.
+
+The explosions made great havoc with the barricade, and presently
+the line was broken and the whole mass swung shoreward or drifted
+down stream.
+
+Then Ned called out:
+
+"Now drop down stream and I will join you."
+
+"Better look out where you land!" Harry called back.
+
+"I hope I won't get into any such scrape as you did," Ned replied.
+
+"Oh, you're not out of it yet!" laughed Frank. "These woods are
+full of man-eaters. Look out where you go, and we'll find a place
+for you to come down."
+
+The anchor of the Black Bear was lifted and the power turned on. In
+a minute she was going down stream at a thirty-mile gait.
+
+Directly they passed the wrecked barricade, rolling and tumbling in
+the waters, the canoes either broken or half full of water. The
+Nelson still led the way down the stream.
+
+"I guess he's never going to stop."
+
+"Wonder if he's going back to New York?"
+
+"Perhaps he's lost control!"
+
+The boys looked and wondered as the aeroplane drifted on to the
+north and cast. They were miles from the scene of the battle now,
+but the airship went on.
+
+Presently they saw the purpose of the aviator in making this long
+run. A little nest of houses flashed out on the river bank, with
+here and there a light showing, and here the onward course of the
+Nelson became a circling descent.
+
+In the east there was a faint line of dawn in the sky when the Black
+Bear was pushed up to a primitive wharf. The aeroplane was still
+circling in the air.
+
+"He wants us to pick out a spot for him to land on," Jack said.
+"There's one over by that hill," he added.
+
+When Ned saw the three boys gather at the spot indicated and motion
+to him to come down he lost no time in doing so. When he stepped
+out of his seat all three lads were upon him. One would have
+thought they were determined to tear him in pieces the way they
+seized his hands, his legs, and pulled at his neck.
+
+"You old fraud!"
+
+"How did you know?"
+
+"You're a nice old chaperon!"
+
+For a moment Ned could not say a word, then he pushed the boys away
+and sat down on the ground.
+
+"You're a nice bunch!" he said.
+
+"Sure!" said Jack.
+
+"The people back there thought so much of us that they wanted us to
+remain to dinner!" grinned Harry.
+
+"There ain't no better people!" Frank insisted.
+
+"How did you happen to get out here?" demanded Ned. "Why, you
+fellows ought to have a chaperon. Those cannibals would have had a
+good dinner today if the Nelson hadn't come that way."
+
+"Now, don't crow over us!" pleaded Frank. "We know all about it.
+You've gotten us out of many a scrape, but this is the large event.
+We take off our hats to you. Now, where's Jimmie and Leroy?"
+
+"I don't know," answered Ned, gravely.
+
+"I guess you are the one who needs a--"
+
+"I guess you are right," Ned replied. "I've been up against the
+pricks good and plenty since I left you. If I get to New York
+alive, I'm going to stay there for good."
+
+"Where did you leave Leroy?" asked Frank.
+
+"In jail!"
+
+"Wow!" cried all three boys.
+
+"And Jimmie? I don't see how you happened to lose him."
+
+"Jimmie is lost in the Peruvian mountains," Ned said.
+
+"Well, why don't we go and get him?" asked Harry.
+
+"Yes," laughed Frank. "We might ride in the Black Bear over the
+storm-tossed summits of the Andes!"
+
+"At least," Ned said, "you boys can help me a lot. I have my hands
+full. We can all ride the Nelson, I take it. She was built to
+carry three average-weight men, you know, and I think she ought to
+manage three boys and one man!"
+
+"Oh, you man!" laughed Jack, poking Ned in the side. "You man who
+has to come to the three boys for help!"
+
+"Tell us about it," Frank said.
+
+"The quicker we start in on the search for Jimmie the quicker he
+will be found," Harry insisted.
+
+It was not much of a town where the Nelson had landed. There were a
+few native houses and a great warehouse, at one end of which was a
+small office. Such river products as came from up stream were
+packed there to await transportation down to the Amazon.
+
+By the time the sun was up a score or more natives and a couple of
+British traders were gathered about the aeroplane and the Black
+Bear. One of the traders, Mr. Hamlin, invited the boys to his home
+for breakfast, and left some of his employees on guard at the Nelson
+and the Black Bear.
+
+During the breakfast Ned recounted his adventures, to which the host
+listened with the closest attention. Frank then told of the cruise
+of the Black Bear, adding that they had hoped to reach the very last
+yard of water flowing down the Andes slope to the east.
+
+"It is wonderful what American Boy Scouts will accomplish!" Mr.
+Hamlin said, when the tales had been told. "A few years ago no boy
+of your age would have undertaken such a duty as sent you to
+Paraguay," he added, addressing Ned, "and no boys would have dared
+to navigate the Beni river," he continued, smiling at the three
+bright faces on the other side of the table.
+
+"The Boy Scout training makes for courage and resourcefulness," Ned
+said. "We have not been caught in many traps. In fact, I think we
+are now up against the very worst situation we have ever
+encountered."
+
+"But you haven't yet told us how you got out of jail at Asuncion,
+only that you got in on a smuggling charge and were released. Who
+brought about the release?"
+
+"The president of the Republic," was the reply. "He learned of the
+matter and ordered me brought before him. Well, I had been
+searched, and the Nelson had been searched, and nothing found, so I
+was let go. The president also ordered the Nelson returned to me.
+It had been appropriated by an official who had declared it
+forfeited. Not a bad chap that president, still, I think he saw
+Uncle Sam in the background!"
+
+"And about this man Lyman?"
+
+"I was told that he had gone back to his concession. I went out
+there in the airship, but failed to find him. After we find Jimmie
+and get Leroy out of the jail at Lima I'm going to find Lyman once
+more."
+
+"This," Jack said, "is the 23d of August. Now, we saw you last
+night, the 22d, and the night before, the 21st. Why didn't you come
+down then?"
+
+"Because I was not certain that it was the Black Bear, and because I
+wanted to investigate the place where I last saw Jimmie and the man
+Jackson. I was over the boat longer ago than the night of the 21st,
+but you did not know it, I guess."
+
+"Well, you came at the right time, when you did come," Jack said.
+"I only wish you hadn't found us in such a pickle!"
+
+"It doesn't seem to me," Mr. Hamlin suggested, "that the Nelson
+ought to carry four. You may have to go pretty fast. Now, one of
+you can remain with me, in welcome, and look after the Black Bear.
+I have plenty of gasoline, and we can amuse ourselves with trips on
+the river. Later, you can come back after the boat."
+
+"I think I'd better stay," Harry Stevens said. "I'm not stuck on
+long rides in the air. Besides, you can do just as well without me.
+How far is it to the place where you left Jimmie and this man
+Jackson?"
+
+Ned took out his pocket map and bent over it.
+
+"Here we are," he said, presently, "in the valley of the Madeira,
+with a range of mountains on each side. Below are the rapids and
+the falls. You must have had a sweet time traveling up from Fort
+San Antonio. You passed about three hundred miles of swift rapids
+and falls. How many times did you have to take the Black Bear to
+pieces?"
+
+"Not once there," was the reply. "We managed to steam up. But,
+say, we had a lovely time getting up over one waterfall!"
+
+"Well," Ned went on, "here we are at the big bend of the upper
+Madeira. We are not far from a thousand miles from the place where
+I found Lyman. We can get there by nightfall."
+
+"Not for me," Jack said, with a shrug of the shoulders. "We should
+have to ride continuously to make it in that time, and I don't like
+to remain in the air that long. We ought to have five rests of an
+hour each, and get there in the morning."
+
+"Yes," Ned replied, "I'm getting tired of long rides myself. We'll
+go slower."
+
+After breakfast the boys went to the Black Bear and looked her over.
+The propeller which had been broken could easily be repaired, they
+found, so they left that matter to Harry, replenished the tanks of
+the Nelson with gasoline, and prepared for the long journey back to
+the mountains of Peru.
+
+"When are you coming back?" asked Harry, as the three mounted the
+machine.
+
+"In three days," replied Ned. "And we'll bring Jimmie with us."
+
+"If they haven't fed him to the mountain lions before now!" Harry
+said, with a strange premonition of evil in his heart.
+
+And the Nelson was up and away, and Harry set to work cleaning up
+the motor boat, hoping to forget in toil how lonely and apprehensive
+he was.
+
+
+
+
+CHAPTER XVII
+
+USING BOY SCOUTS FOR BAIT!
+
+
+Alarmed by the swift approach of the motor car in the tunnel, Jimmie
+and Jackson took to their heels and made swift progress toward the
+east entrance, throwing the searchlight about and keeping their eyes
+out for some hiding place as they ran.
+
+Before long it became evident that they could not long maintain the
+pace they had taken. The motor car was gaining on them rapidly, as
+they knew by the steady approach of the clamor which the engines
+were making.
+
+"Gee!" cried Jimmie, at last. "No use! I've got to drop in
+somewhere!"
+
+Jackson was as ready to stop running as was Jimmie, so they drew up
+against the wall and Jimmie shut off the light from his electric
+candle.
+
+"Do you think they saw that light?" asked Jimmie, pushing close to
+the rock wall. "I hope not."
+
+"Probably not, as there was always an angle between us," was the
+whispered reply, "but their light is coming around that angle now.
+Stand close!"
+
+It was of little use to stand close.
+
+Under the great lamps every crack and crevice of the tunnel walls
+was in plain sight to the occupants of the car. The two fugitives
+might as well have attempted concealment under the limelight in the
+center of the stage of a Broadway theatre!
+
+Jimmie's hand was on his automatic as the car halted in front of
+him. Jackson saw what was in the boy's mind and laid a hand on his
+arm.
+
+"None of that!" he said.
+
+"Well, I'm not goin' to be--"
+
+Jackson forced the revolver out of the boy's hand as he brought it
+out of his pocket.
+
+"They've got us," he whispered, "and will be only too glad of an
+excuse to shoot us down in cold blood."
+
+"Well!"
+
+This from Thomas Q. Collins, who sat in the front seat, looking at
+the two as if he could bite them in pieces!
+
+Jimmie looked sullenly toward his automatic, in Jackson's hand, and
+said not a word. Jackson stepped forward.
+
+"You've got us!" he said.
+
+"You bet we have!" gloated Collins. "Where did that Nestor boy go
+with the man he picked up by the fire?"
+
+"Did he get him?" asked Jimmie.
+
+"Yes, he got him, worse luck!" was the reply. "Where did he go with
+him?"
+
+"Don't know," replied Jimmie.
+
+"I'll find a way to make you know!" gritted Collins. "Do you
+fellows know what it is to be hungry?"
+
+"Honest," Jackson cut in, "we don't know where Nestor went with
+Lyman. When he left us, he was not certain that he could get him.
+Thought Lyman might not want to go away with a stranger on such
+short notice."
+
+"Oh, what's the use?" demanded one of the others. "The fellow has
+gone back to Asuncion. That's easy to figure out. Who set you boys
+at work on this case?" he added, in a moment, at a whisper from his
+seat-mate.
+
+"Ned set me at work," Jimmie answered.
+
+"Yes, but who set him at work?"
+
+"I'll tell you," Jackson said, with a smile of satisfaction on his
+face, "the United States government set Ned at work. You'd better
+watch out how you butt up against the Secret Service men."
+
+"That's just what I told you!" sneered Collins. "You wouldn't
+believe me. Now what do you think?"
+
+The speaker left his seat in the machine and walked over to where
+Jackson was standing, the revolver still in his hand.
+
+"Give me that gun!" he demanded.
+
+Jackson passed it over without a word of protest.
+
+"Now your own gun," Collins demanded, extending his hand.
+
+"I have no gun," was the reply. "You know that very well."
+
+"I thought you might have stolen one since leaving the cow country,"
+snarled the other. "There is no knowing what kind of property you
+light-fingered gentlemen will acquire."
+
+"You're a liar, Collins," Jackson said, coolly. "You know I never
+ran off the cattle which were missed. I believe you stole them!"
+
+Collins advanced angrily toward the speaker, but one of his company
+drew him back.
+
+"Cut it out!" he said. "There will be plenty of time later on."
+
+"What are you going to do with us?" asked Jimmie.
+
+"You'll see!" Collins replied. "I wonder how you would like a game
+of chase-the-bullet? Similar to the one you gave me not long ago?"
+
+"Like it fine," Jimmie grinned, "if it didn't do me no more harm
+than it did you. Never touched you!"
+
+"It may be different in your case," Collins threatened.
+
+After consulting together in whispers for some moments, the men
+loaded Jimmie and Jackson into the crowded motor car and put on the
+reverse movement. In half an hour, the progress being slow, they
+came to the valley where the campfire was still burning. Here they
+all alighted.
+
+Half a dozen Peruvian Indians of vicious appearance now came
+forward, and Collins gave them instructions in an undertone, after
+which the two captives were led away to the cavern in which Lyman
+had been sheltered up to the time of the arrival of the Nelson. One
+of the Indians remained outside while the others hastened away.
+
+"Well," Jimmie said, as he looked gloomily at the discouraged
+Jackson, "what do you think of this? I'd like to push the face of
+that Collins person in so it would mix with the back curtain."
+
+"We're in for it!" moaned Jackson.
+
+"Aw, what can they do to us?" demanded the little fellow.
+
+"They can keep us here until we die of starvation," replied Jackson.
+"I've had a turn with starvation, and know what it's like."
+
+Jimmie reached under his coat and brought out a can of beans.
+
+"Here," he said, "get busy on this."
+
+"They took mine away when they searched me for a gun," said Jackson.
+
+"Buck up!" advised Jimmie. "We've got to figure out some way to
+give them the slip. What?"
+
+"Yes, I suppose so!"
+
+Jackson had counted on getting back to civilization without further
+difficulties, on the arrival of the Nelson, and now he was
+completely discouraged. Jimmie sat on the floor of the cavern and
+eyed him quizzically.
+
+"Ned will come back after us," the little one said, presently. "You
+put your bloomin' trust in Ned, an' you'll come a four-time winner
+out of the box. I know. I've been out with him before."
+
+"But how will he ever find us here?" asked Jackson.
+
+"How did he ever find Lyman?" demanded the boy. "You hush your
+kickin' an' leave it all to Ned. Guess he knows enough to get us
+out of this sink of iniquity! That boy eats 'em alive!"
+
+"I can't see why they should keep us here," Jackson remarked,
+presently, prying off the top of the can of beans with his pocket
+knife. "Why don't they go back to Asuncion and look after that
+cattle concession?"
+
+"Because they've got some one there to look out for it for them,"
+replied the boy. "They're waitin' here for Ned to come back an' get
+us, if anybody should ask you," he went on, his cheerful smile not
+at all matching the serious import of his words. "This Collins
+person has cards up his sleeve, an' he wants to get hold of Ned.
+He's set his trap with us for bait."
+
+"You're a cheerful little cuss!" grinned Jackson, beginning to see
+the dangerous side of the situation. "And what are we going to do
+when Ned comes back? Let them soak him?"
+
+"Not so you could notice it," was the reply. "When Ned comes back
+we'll be out at the other end of that tunnel, an' he'll swoop do in
+in the Nelson an' pick us up, an' we'll be back in little old N. Y.
+before you can say scat."
+
+"But how can we--"
+
+The entrance to the cavern was darkened for a moment and then the
+flashily-dressed form of Collins made its appearance.
+
+"What's that about getting back to little old N. Y.?" he asked.
+"When do you start for Manhattan Island?"
+
+"You heard, then?" asked Jackson.
+
+"Of course."
+
+"Well?"
+
+"Well, we'll see that you don't get away until this Ned comes back
+after you. We need him in our business."
+
+"He'll land Lyman at Asuncion before you see him again," Jimmie
+said.
+
+"Not a doubt of it," was the sullen reply, "but don't you ever think
+we haven't got people there who will look out for our interests.
+Lyman won't be at liberty long, and your Ned will come back here to
+get what's coming to him."
+
+"Is that so?" exclaimed the boy, putting on a bold front, but
+inwardly fearful that the situation was a tragic one.
+
+Leaving the captives with this cheering (?) information, Collins
+went back to his companions, leaving the Indian still on guard. For
+a time the Indian stood stolidly in front of the cave, then, looking
+carefully about to see that he was not observed by his employers, he
+faced the opening and uttered one English word:
+
+"Prepared."
+
+Jackson opened his eyes in amazement, but Jimmie saw an extended
+hand and sprang forward. The Indian's right hand was extended
+toward the boy, palm up, the thumb and little finger meeting across
+the palm and crossed, the remaining fingers straight out.
+
+"You mean, 'Be prepared'?" Jimmie asked.
+
+"'Be prepared,"' repeated the other, like one rehearsing a lesson.
+
+"Gee!" laughed the boy. "Here's a Boy Scout lingerin' in little old
+Peru! Now wouldn't that stop a clock?"
+
+"You just wait a minute," Jackson said, hopefully. "I think I can
+talk with this chap a little in Spanish."
+
+Then followed a great picking of words to match gestures, and
+gestures to explain words, during which the full salute of the Boy
+Scouts of America was often repeated by the Indian. Then Jackson
+said:
+
+"He says that there were Boy Scouts down here six months ago, and
+that he guided them through the mountain passes to the headwaters of
+the Beni river. From there they went through to the valley of the
+Amazon in a boat--a steam launch."
+
+Jimmie reached under his waistcoat collar and produced his Wolf
+badge, pointing to it with his finger inquiringly. The Indian shook
+his head.
+
+"Not Wolves," the boy said, in a moment. "Let's see if they were
+Black Bears."
+
+When a Black Bear badge which belonged to Jack Bosworth was shown
+the Indian still shook his head. Then he pointed to the sky and
+whirled his hand around significantly, finishing with a waving,
+flying motion.
+
+"I see!" cried Jimmie. "They were Eagles!"
+
+"This ought to help some," Jackson observed, his face growing more
+cheerful.
+
+"Of course it will," replied the boy. "Ask him if he wants to get
+out of this blasted country and go to New York. We'll take him if
+he'll get us out on the east slope before Ned gets back."
+
+Jackson talked with the Indian again, but did not seem to be able to
+come to terms with him.
+
+"He doesn't want to commit himself," the ex-cattleman said. "We'll
+have to wait until he thinks it over."
+
+The Indian seemed moody and sullen for the next few hours. When
+dawn came and the little fire which had blazed in the cavern all
+night went out, he was called away and another native placed on
+guard.
+
+"That settles it," Jimmie said. "We lose!"
+
+"I'm the losenest feller you ever seen," said Jackson. "I never won
+a bet in my life. You're unlucky to get dumped in a mess with me."
+
+About the time Ned and Lyman landed in Asuncion the boys in the
+cavern began looking for his return. They were not permitted to
+leave the cavern, but they watched the eastern sky intently every
+minute.
+
+They watched the sky, too, during the long days when Ned was in
+prison at Asuncion. Late on the afternoon of the 21st, as the
+reader knows, Ned searched the eastern slope for them but they did
+not see him. On the morning of the 23d they were taken from the
+cave and placed in full sight on the eastern slope, where they would
+be sure to be seen from the sky. They did not know what to make of
+this at first, but directly, when they saw Indians, heavily armed,
+stationed in hiding places all about them, they understood.
+
+Jimmie had expressed the situation exactly. The cowards were
+baiting their trap for Ned with his friends.
+
+Unless some means of warning him could be found, Ned would drop down
+to his death if he landed to rescue the ones he had left behind.
+
+
+
+
+CHAPTER XVIII
+
+THE END OF A LONG CHASE
+
+
+On the 23d of August the Nelson, with Ned, Jack, and Frank on board,
+was sweeping over the mountains and valleys of Bolivia and Peru
+toward the twin valleys in which Jimmie and Jackson had been left.
+Plenty of provisions and gasoline had been taken on at the Hamlin
+storehouse, and the lads were well equipped for a week's cruise in
+the air.
+
+They did not urge the aeroplane to its fullest speed, nor did they
+remain in the air longer than a couple of hours at a time. It had
+been decided to strike the eastern slope of the range just before
+dawn, so the Nelson was allowed to loiter on the way. Jack
+afterwards declared that Ned slept half the time!
+
+Had the first decision, to run to the twin valleys as swiftly as
+possible, been held to, the two prisoners, guarded on that eastern
+slope, would have seen the Nelson coming toward their relief.
+
+At the same time, on landing, Ned and his companions would have been
+confronted with armed Indians demanding immediate surrender. This
+would not have been according to the notions of the boys on the
+aeroplane, as they had figured that Jimmie and Jackson would be able
+to keep out of the hands of the Collins gang.
+
+The 23d dawned slowly, with the Nelson loitering over the great
+brown and green map of South America and the boys tiring their eyes
+looking for the glistening planes of the aeroplane. The captives
+were provided with food, but it was decidedly cold on the
+mountainside when night came.
+
+All that day and all that night the guards lay in wait in
+sequestered places, waiting for the Nelson. Although his only hope
+of immediate rescue lay in the arrival of the Nelson, Jimmie wished
+every minute of the time that Ned would in some manner be warned
+away from that dangerous locality.
+
+Just before dawn of the 24th Jimmie, who had fallen into a light
+slumber, felt Jackson pulling at his arm.
+
+"Wake up!" the man whispered. "There is a light in the sky!"
+
+Jimmie was on his feet in an instant. Away off over a parallel
+ridge to the east, a ridge not so high as the one on which they
+stood, and which formed only a slight elevation in the general
+slope, a single light twinkled and swung up and down in the half
+light between night and morning. "That's the Nelson, all right!"
+Jimmie declared. "Ned is coming! Good old Ned! Now, what can we
+do to keep him from being murdered?" the boy added, tearfully.
+
+"I give it up!" replied Jackson. "All we can do is to give them
+some signals and tell them to keep away."
+
+Jimmie sprang out to one of the guards, who already stood erect,
+watching the light with his gun in his hand. The guard looked
+curiously at Jimmie as he advanced, his hands clasping his
+shoulders, his body shivering as from extreme cold. The Indian was
+cold, too, so it did not take him long to make out the boy's
+meaning.
+
+Jimmie next pointed to sticks lying about, and to bunches of dry
+grass which stood in some of the crevices of the rocks. The guard
+nodded consent for a fire and Jimmie raced about like mad collecting
+principally dry grass.
+
+Jackson ran to help him, piling his gatherings all on one heap.
+
+"Make three piles!" Jimmie cried. "I want three fires! Three
+bright fires! Make three heaps!"
+
+The three heaps grew fast. They were not arranged in a row on a
+level, but mounted one above another on the slope. Jimmies idea was
+to so place the fires one above the other, some thing like notches
+cut in a tree trunk.
+
+The reason for this is apparent. Three fires in a line facing the
+point signaled to signal "Good News." Three notches cut in a tree
+trunk, one above another, mean "Important Warning!" Now the
+question was, would Ned understand that the fires represented
+warning notches, one above the other, and keep away until some safe
+plan for landing could be arranged?
+
+If he accepted the signal as "Good News" signs, he would drop down
+to death. If he read them as Jimmie intended he should, he would
+sail away and wait for a more favorable opportunity.
+
+When the three fires were going the Indian guards gathered about in
+order to warm themselves. Jimmie and Jackson hovered near them,
+too, but they never shifted their eyes from the light in the sky.
+
+The Nelson hovered over the elevation to the east for a second, and
+then, much to the amazement of the lad, whirled about and shot
+downward, out of sight. The guards watched the light as long as it
+showed and then turned to the fires again.
+
+Daylight came swiftly, and a finger of sunlight lay on the crest of
+the mountains when the' machine was in the air again. It was,
+perhaps, three miles away, across deep and dangerous canyons which
+it would require hours of the hardest kind of traveling to cross on
+foot.
+
+Sailing low, almost touching minor elevations at times, the great
+airship came on, straight to the spot where the boys stood--where
+the Indians awaited them with guns in their hands!
+
+In a moment Jimmie saw why this course was being taken. Unless the
+rascals in the twin valleys had seen the light when it first
+appeared they would not see it at all, for the bulk of the mountain
+shut off their view of the rough country over which Ned was
+traveling.
+
+Ned did not seem to mind the fire signals. Perhaps, Jimmie thought,
+he had recognized the warning as a "Good News" signal. In that case
+the boy thought, the end of everything, for them, would come right
+there!
+
+Moving slowly and softly, with little noise of motor or propeller,
+the Nelson approached the spot, circled about, and dropped in a
+little depression just below the place where Jimmie was standing.
+Then the strangest thing happened!
+
+The boy had expected to hear rifle shots, to see his friends
+attacked, perhaps murdered before his eyes. But the first one to
+spring from the machine was the Indian who had given the Boy Scout
+salute some days before!
+
+The Indians on guard saluted him gravely and stood eyeing the
+aeroplane critically. No hostile move was made. It was the
+strangest thing! Where had Ned taken the Indian up, and why had the
+latter volunteered to render this assistance?
+
+It was no use to wonder, so Jimmie and Jackson sprang toward the
+machine, grasped Ned by the hand, and swung into seats. The Indian
+who had piloted the Nelson to the place and prevented an attack by
+the guards, stood with his arms folded across his broad breast. For
+a moment Ned grasped his hand. The others followed, with what
+emotion may well be understood, and the Nelson was away, purring
+through the sweet air of the morning as if there were no perils at
+all in life!
+
+Later revelations showed that the Indian, wishing to protect the Boy
+Scouts, had made his way to the elevation where the Nelson had first
+dropped down, signaled to Ned, and informed him of the plans of the
+Collins people. Frank and Jack had been left farther down the
+slope, as it was feared that the Nelson would not be able to get
+away with so much weight to carry. It is almost needless to say
+that the Indian was rewarded for his loyalty to the Boy Scouts, and
+that he carried back with him enough money to make each of the
+guards a substantial present.
+
+When the Nelson first rose above the rim of the twin valleys shrill
+cries came from the direction of the cavern, and half a dozen shots
+were fired. But all to no purpose. The last the boys saw of
+Collins and his adherents they were shouting angrily at the Indians,
+who were rapidly disappearing from sight over the west wall.
+
+After a time the aeroplane dropped down again, and Jimmie's eyes
+nearly popped out of his head when he saw Jack and Frank sitting
+complacently on a rock watching him with grins on their faces. The
+greeting of the three boys may well be imagined.
+
+"You're a nice bunch!" Jimmie cried, after many handshakes and much
+pulling about. "We left you on the way to little old N.Y. Where
+you been?"
+
+"We just took a run in the Black Bear!" was the reply.
+
+"The Black Bear!" repeated the little fellow actually rubbing his
+eyes to see if he was awake. "Where is the Black Bear?"
+
+"Down in the Madeira river," laughed Ned, "and there's no knowing
+where she would have been by this time only for the--"
+
+"Cut it out, Ned!" broke in Jack. "Let us break it to him gently.
+He'll have fun enough with us without getting it all in a bunch!"
+
+Jackson was introduced to the two boys, and then a council of war
+was held. It was finally decided that Jackson should be taken to
+Sicuani in the Nelson and left there, with money enough to make his
+way out. Pedro was found at Sicuani and richly rewarded. He did
+not return to Lima.
+
+Then Ned was to return for the boys and proceed straight to
+Asuncion, where the search for the missing cattleman was to be
+renewed. This programme was carried out. Later the boys met
+Jackson in New York and royally entertained him at the Black Bear
+club room and saw that he secured a fine position.
+
+When the Nelson reached Asuncion Ned proceeded directly to the
+office of the president, taking the boys with him. There the story
+of the trip was told, and Frank and Jack saw to it that Ned's
+official position was made known to the head of the republic.
+
+"And so this Mr. Thomas Q. Collins is the man at the bottom of the
+trouble?" asked the official. "Well, he will be taken care of if he
+returns here. And this military chief? He shall be sent out of the
+country!"
+
+It transpired later on that the president had been deceived in the
+two men, and that Collins had secured the assistance of the general
+by false statements and by offers of large sums of money in case the
+cattle concession was taken from Lyman. A good many officials were
+found to be mixed up in the conspiracy, and there were numerous
+vacancies in the government service.
+
+"And now," the president said, after the whole truth was known, "the
+next thing to do is to find Lyman and restore him to his rights."
+
+"It seems to me," Ned suggested, "that this general ought to be able
+to produce him in Asuncion in a few hours' time."
+
+"It may be so," admitted the official. "At least, we'll see what
+can be done in that direction."
+
+Lyman was safe in his home in one day. When the general learned
+that it was the wish of the president that the cattleman should be
+brought forth, the thing was as good as accomplished.
+
+"It seems to me," Ned said to the boys, that night, "that this thing
+has been settled without much help from me. All the president
+needed was to be set right."
+
+"What he needed," laughed Jack, "was the proof that Collins had
+abducted Lyman, and that he was prepared to prevent his return to
+Asuncion until his concession had expired. Perhaps you can tell me
+how all this proof could have been obtained if you had not
+undertaken the job offered you by the Secret Service men at San
+Francisco?"
+
+"Of course he can't," Jimmie put in. "Lyman man would have died
+there in the mountains and Collins would have taken over his
+property. The president might have been in with the deal at first,
+but he certainly wasn't willing to stand for such coarse work."
+
+"And when Lyman didn't show up, his heirs would have demanded the
+property, and then there would have been an international
+quarrel--perhaps work for gunboats," Frank added. "I think the case
+was settled just right, and in the right way."
+
+"And what does this Lyman person say?" asked Jimmie.
+
+"Not a thing!" cried Jack. "He just offers Ned all the money there
+is in the world in the shape of a reward. I should have taken it!"
+
+"I know better," Ned commented. "We don't need his money, any more
+than we need the half million or so Collins offered us."
+
+"Wonder what Collins will do now?" asked Frank.
+
+"He'll duck!" replied Jimmie.
+
+The little fellow was right. Thomas Q. Collins was heard of no
+more, either in Paraguay or Peru. When Ned, leaving the others at
+Asuncion, speeded over to Lima he found Leroy and Mike lounging
+about the hotel, waiting anxiously for news from their chums. They
+had been released on the day following Collins' departure, there
+being no one to press the charge of assault and battery against
+them.
+
+Now there was work cut out for the Nelson. She carried Ned, Mike
+and Leroy over to Asuncion and then made two long trips to the
+little town on the Madeira where the Black Bear lay.
+
+The meeting between the boys and Harry was an enthusiastic one, and
+the latter pointed with a good deal of pride to the motor boat, good
+as new and as bright and clean as a new gold piece.
+
+After a few days spent exploring the country up the Beni, the boys
+started home, their errand satisfactorily accomplished. Jimmie
+decided to go with Jack, Frank, Harry and Mike in the motor boat,
+leaving the Nelson to Ned and Leroy.
+
+"One thing I'd like to do," Jimmie said, as the Black Bear lay
+waiting for the boys, "and that is to go up into that cannibal
+country and have some fun with the fellows who captured the Black
+Bear and made the occupants of it look like thirty cents in postage
+stamps!"
+
+"They never did capture the Black Bear!" yelled Frank. "They tried
+to, and got dynamited for their pains. That's what they got."
+
+"And of course," tormented the little fellow, "you wished the Nelson
+had stayed away, and left you all the glory--not!"
+
+"Well," Jack interposed, "we didn't get tied up in a mountain cave
+by a lot of cheap skates. We never got where we had to let an
+Indian get us out of a mess."
+
+"Rats!" shouted Jimmie. "Ned would have recognized our fire signals
+and remained away! We could have gotten off without the Indian."
+
+"You say it well!" laughed Frank. "I think that fire signal was
+punk!"
+
+And so the lads roasted each other all the way down the Amazon, with
+the Nelson sailing above them, dropping down at night and, perhaps,
+changing passengers each day.
+
+"I wish I had the frame of the Vixen," Leroy said, one day. "I
+could make a fine aeroplane out of it. Shame to have an airship
+smashed like that!"
+
+Ned pointed to the planes of the Nelson.
+
+"You've got quite a job making this little lady look like new," he
+said. "Those tent canvas planes look rather cheap."
+
+"I'll have the new planes in place in a week after we get back to
+New York," said the other.
+
+"And send the repair bill to the government," advised Ned. "It will
+be paid without a cross word."
+
+At the mouth of the Amazon the Black Bear was taken apart and packed
+aboard a fast steamer bound for New York. The five boys accompanied
+her, of course, while Ned and Leroy completed the trip home in the
+Nelson. When the four reached the Black Bear club room they found
+Ned there with a mass of letters and telegrams before him.
+
+"Look here, lads," he said, "we've got more trouble on hand. You
+know about the revolution in China, and all that? Well, there's a
+lot of gold which belongs to the republic been dumped in the sea,
+and I've got to go and help get it out!"
+
+"Let 'em get their own gold," Jimmie said.
+
+"But in this case, it is claimed that there was fraud in the
+shipment of gold, also, that the vessel carrying it was rammed for
+the purpose of concealing the fraud. Anyway, Uncle Sam wants me to
+look it up."
+
+"What's he got to do with it?" asked Frank.
+
+"Something connected with the sub-treasury," laughed Ned. "That is
+all I can say to you about it."
+
+"And how you goin' to get it?" demanded Jimmie.
+
+"By working with a submarine," was the reply.
+
+"Down in the bottom of the sea!" sang Frank.
+
+"Well," Ned said, presently, "figure the thing out for yourselves.
+Find out if you can get permission to go, and all that. The
+government will provide the submarine and all the supplies, of
+course, and land us near the spot we are to search."
+
+But the story of the search for the gold is quite another tale. It
+will be found in the third volume of this series, entitled:
+
+"Boy Scouts in a Submarine; or, Searching an Ocean Floor."

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.

+CHAPTER I
+
+SPIES IN THE BOY SCOUT CAMP
+
+
+Gates, the United States Secret Service man, closed the door gently
+and remained standing just inside the room, his head bent forward in
+a listening attitude. Ned Nestor and Jimmie McGraw, Boy Scouts of
+the Wolf Patrol, New York City, who had been standing by a window,
+looking out on a crowded San Francisco street, previous to the
+sudden appearance of the Secret Service man, turned toward the
+entrance with smiles on their faces.
+
+They evidently thought that Gates was posing, as so many detectives
+have a silly habit of doing, and so gave little heed to the hand he
+lifted in warning. The boys knew little about Gates at that time,
+and so may be pardoned for the uncomplimentary thoughts with which
+they noted his theatrical conduct.
+
+Young Nestor had been engaged by the United States government to
+undertake a difficult and dangerous mission to South America, and
+Gates had been sent on from Washington to post him as to the details
+of the case. The boys had waited at the San Francisco hotel three
+days for the arrival of the Secret Service man, and waited
+impatiently, as Sam Leroy, who was to be the third member of the
+party, was anxious for the safety of his aeroplane, the Nelson, in
+which the trip to "the roof of the world" was to be made.
+
+The Nelson was lying, guarded night, and day, in a field just out of
+the city, on the Pacific side, and Leroy was impatiently keeping his
+eyes on the guards most of the time. There was a subconscious
+notion in the minds of all the boys that there were enemies about,
+and that the aeroplane would never be fully out of danger until she
+was well over the ocean on her way south. Gates had arrived only
+that morning, and now the lads were eager to be off.
+
+A couple of hours before his appearance in the room that morning,
+the Secret Service agent had left the boys in the lobby below to
+arrange for the necessary papers and funds for the mission. Before
+going out, however, he had been informed of the boys' suspicions,
+and had made light of the idea that the aeroplane was in danger from
+secret enemies, pointing to the fact that no one was supposed to
+know anything about the proposed journey save the boys and himself
+as conclusive evidence that the suspicion of constant surveillance
+was not well founded.
+
+Now, on his return, his cautious movements indicated that he, too,
+was alarmed and on his guard. While Ned was wondering what it was
+that had so changed Gates' point of view, there came a quick,
+imperative knock on the door of the room, which was occupied by Ned
+and Jimmie as a sleeping apartment.
+
+Instantly, almost before the sound of the knock died away, Gates
+opened the door and stepped forward. The man who stood in the
+corridor, facing the doorway, was tall, slender, dark of complexion,
+like a Spaniard or a Mexican. His black hair was long, straight,
+thin; his black eyes were bright, treacherous, too close together,
+with a little vertical wrinkle between the brows. He was dressed in
+a neat brown business suit of expensive material.
+
+When the door was opened he stepped forward and glanced into the
+interior of the room, apparently with the purpose of entering. But
+when Gates moved aside to give him passageway he drew back, the set
+smile on his face vanishing as he bowed low and swung his slender
+hands out in elaborate gesture.
+
+"Pardon!" he said. "I have made a mistake in the room."
+
+He was about to move away when Gates gritted out a question.
+
+"For whom were you looking?" he asked. "We may be able to direct you
+to your friend," he added, more courteously, his alert eyes taking
+in every detail of the man's face, figure and dress.
+
+"It is nothing!" was the quick reply. "I will make inquiries at the
+office--which, undoubtedly, I should have done before."
+
+In a moment he was gone, moving gracefully toward the elevator.
+Gates watched his elegant, well-dressed figure with a smile of quiet
+satisfaction. When the visitor gained the elevator, he turned and
+bowed at the still open doorway, and the Secret Service man
+recognized the grin on his face as expressive of triumph rather than
+apology.
+
+"What did he want?" asked Jimmie, as Gates, closed the door.
+
+Gates did not answer the question immediately. Instead he asked
+one:
+
+"Ever see that fellow before?"
+
+Jimmie shook his head, but Ned looked grave as he answered:
+
+"I have seen him about the hotel--frequently. He seems to have a
+suite off this corridor, or the one above it."
+
+At this moment the door was opened again and Sam Leroy bounced into
+the room, his eyes shining with enthusiasm, his muscles tense with
+the joy of youth and health. He drew back when he saw Gates, whom
+he had not met before, and looked questioningly at Ned.
+
+"This is Lieutenant Gates, for whom we have been waiting," Ned said,
+"and this, Lieutenant, is Sam Leroy, who is to take us to South
+America in his aeroplane."
+
+"I hope the machine is above reproach as to strength and speed,"
+laughed Gates, as the two shook hands cordially, "for there is
+likely to be doings down there."
+
+"The Nelson is warranted for work and wind," said Ned. "She crossed
+the continent in a rush and spied on us through British Columbia and
+on down the Columbia river, not long ago, and I can recommend her as
+a very desirable bird of the air."
+
+"She's all sound now," Leroy said, "but there's no knowing how long
+she will be if we don't get her out of San Francisco. There was a
+couple of men hanging around her last night, and one of them went
+away with a bullet in his leg. I'm glad you're here, Lieutenant,
+for now we can get away--quick!"
+
+"Did you get a good look at either of the two men you speak of?"
+asked Ned, his mind going back to what seemed to him to be a secret
+conspiracy against the Nelson.
+
+"One of them," Leroy answered, "was tall, slender, dark; with long
+straight hair and eyes like a snake. I noticed, too, that he had a
+habit of moistening his lips with the end of his tongue, and that
+made me think of a snake thrusting out his tongue. I got a shot at
+the other fellow, but not at this one."
+
+Gates and Ned looked at each other with nods of mutual
+understanding. This was a pretty good description of the man who
+had just stood before the door of that room. Then the lieutenant
+turned to Jimmie.
+
+"You asked a moment ago," he said, "what the fellow wanted here.
+Now I think I can tell you. He wanted to confirm his suspicions
+that the four of us axe working together. He has been sleuthing
+about the corridors all the morning, watching me; and his mission to
+this room was to make sure that my business in San Francisco is with
+Ned--that we are working together."
+
+"He's sure doing a lot of Sherlock Holmes stunts," Jimmie declared.
+"And I reckon he's next to his job, for he appears to have inspected
+all the points of interest, from the field where the Nelson is to
+the room where the plans are being made."
+
+"Yes," Leroy said, his manner showing apprehension as well as anger,
+"but how the Old Scratch did he get his knowledge, of what, we are
+about to do? I thought no one in the West knew except us four. And
+what's he trying to do, anyway? What difference does it make to him
+if we do go to South America in an aeroplane?"
+
+"I have a notion," Gates replied, "that he objects to your going in
+an airship because you will make such swift time. Let me tell you
+something more about this case. Then you will be able to understand
+why efforts may be made to prevent your going to South America, in
+an airship or in any other way."
+
+"It's just the airship they've been after so far," Leroy
+interrupted. "They haven't troubled us--and they'd better not!"
+
+"I imagine," said the lieutenant, gravely, "that their activities
+will broaden out as they get warmed up to their work. Understand?
+What I mean is this: You boys are risking your lives in undertaking
+this mission. You will be followed and spied upon from the minute
+you leave San Francisco, and the chances will be all against you
+when you reach your field of operations. Even the Government cannot
+protect you in your undertaking, for the Government is not supposed
+to know anything about this case."
+
+"We are to do something by stealth, then, which the diplomats of the
+State department are too cautious to undertake?" asked Ned.
+
+"That is it exactly," was the reply. "If the State department
+should take cognizance of the situation down there and make any sort
+of a demand, war would be certain to follow in case the demand was
+denied, which it would be. Therefore, the State department does not
+wish to make a demand. Still, the American who is in trouble must
+be protected. You are to go and get him out of his dungeon, or
+wherever he may be, and the Department of State will wink at what
+you do and look innocent."
+
+"Aw, why don't they send a warship to do the job?" demanded Jimmie.
+
+"Because," replied the lieutenant, "Uncle Sam has taken the
+republics of South America under his protection, and he does not
+care to spank them in the presence of all the nations of the earth!
+He wants to get this man Lyman--Horace M. Lyman, to be exact--out of
+the clutches of a crooked gang in Paraguay without wasting money and
+lives. Hence the arrangement with you boys."
+
+"I have read something about the Lyman case," Ned observed, "but I
+have forgotten all the material points, I guess."
+
+"Lyman," Gates went on, "took up his residence in Paraguay some
+years ago and opened negotiations with the government for a cattle
+concession. The lands known as the 'Chaco' district, lying between
+the Paraguay and Pilcomayo rivers, are said to be the best for
+grazing purposes in all South America. Years ago they were
+considered worthless swamps, but this is all changed now.
+
+"Well, Lyman entered into negotiations with the president of this
+alleged republic and got his concession. There is no knowing how
+much he paid for it, for every new president of Paraguay--and they
+have new ones quite frequently down there--seems to do business on
+the theory that what he doesn't get while the getting is good he
+never will get at all. There have been four or five new official
+heads of this alleged republic within a couple of years.
+
+"The country is on the verge of revolution most of the time and as
+the army goes so goes the election. Jara was made prisoner last
+July, and one Rojes put in power. Now, in order to keep in good
+standing with the army, the government is obliged to have generals
+who are loyal to whoever is in power. These generals must be paid
+for their services, of course.
+
+"It seems that Lyman fell under the displeasure of one of these
+powerful military chaps, probably because he refused to give up all
+his profits in the cattle business. Anyway, Lyman disappeared from
+home, quite suddenly, and his manager was notified that settlement
+could be made with one Senor Lopez, an army chief, said to be a
+relative of a former president. So Lopez was appealed to.
+
+"Now Lopez is a slippery chap. He denied knowing anything about
+Lyman, but declared that unless the cattleman appeared shortly and
+took up his work on the cattle concession the grant would be taken
+from him. That is like South American justice. Lock a man up and
+then deprive him of his rights because he can't appear and claim
+them!"
+
+"Must be a fine healthy country!" Jimmie interposed.
+
+"It is all of that," laughed the lieutenant. "Then this manager, I
+think his name is Coye, appealed to the United States consul and the
+consul to the president. Nothing doing! Lyman, they insisted, had
+not been molested by the authorities. But Lyman's people in this
+country are kicking up an awful row, and something must be done.
+
+"There is no doubt that the cattleman, is locked up in some of the
+old military prisons of the country, yet the State department can't
+get him out. The president offers any assistance in his power, of
+course! Lopez weeps when the matter is mentioned to him--weeps at
+the unfounded suspicions which are being cast upon him! So there
+you are! The only hope for Lyman lies in some such method as has
+been planned. If you fail, the situation will be desperate,
+indeed."
+
+"Why don't Lyman buy the fellow off?" asked Jimmie.
+
+"The purpose of Lopez in pursuing the course referred to is
+undoubtedly to find an excuse for robbing Lyman of the concession
+and selling it to another at a much greater price. So others
+besides the general and Lyman are concerned in this mix-up."
+
+"You refer to a person, or corporation, waiting to buy the
+concession?" asked Ned, the reason for the surveillance in San
+Francisco coming to him like a flash.
+
+"That is it."
+
+"And these prospective concessionaires are looking to it that Lyman
+gets no aid from this country?"
+
+"I had not looked at the matter in that way, had not thought of
+their venturing over here, but presume you are right."
+
+"Look here," Leroy asked, "are you figuring it out that the people
+who are trying to steal or cripple the Nelson came here from
+Paraguay for the express purpose of watching this Lyman case and
+preventing his friends from assisting him?"
+
+"You state the case in a way which gives it a good deal of
+importance," Gates replied, "But I believe you state it correctly.
+Just how the men who hope to gain the concession if Lyman loses it
+came to understand the attitude of our Government is more than I can
+imagine, but it is quite clear to me that they do understand the
+situation--that they are thoroughly posted as to every move that has
+been made by the Government and by the friends of the cattleman."
+
+"It is a good thing to know that we are likely to be chased to South
+America," Ned said, "for we know exactly what to expect, and shall
+be on our guard."
+
+"Chased to South America!" laughed Leroy. "They'll have to go some
+if the keep up with the little old Nelson! She can fly some--if you
+want to know!"
+
+
+
+
+
+CHAPTER II
+
+A FOX JOINS THE WOLVES
+
+
+Nelson hung like a great gull over New Orleans one hot morning in
+early August. The boys who occupied seats on the light aluminum
+form under the sixty-foot wings glimpsed the Gulf of Mexico in the
+distance, while directly their feet ran the crooked streets of the
+French Quarter.
+
+The departure from San Francisco had been for a delayed for a long
+time because of the non-arrival of important instructions from
+Washington, and because of a slight injury to the aeroplane while
+out on what Leroy called an "exercise run." Lieutenant Gates had
+remained with the boys until they started on their long flight to
+the mouth of the great Mississippi river, and had then returned to
+Washington.
+
+I had first been the intention to proceed due from San Francisco,
+then wing toward the east where the coast of Peru showed. This plan
+was opposed by the lieutenant, for the reason that an airship far
+out on the Pacific ocean, directly in the steamship route, would be
+likely to attract attention sailing over the southwestern states and
+Central America. Daring aviators now venture in all directions and
+at all altitudes above the solid earth, but they are still cautious
+about proceeding far out over the merciless waters of the oceans
+which rim the continent of North America.
+
+So, yielding to the wishes of the lieutenant, the Nelson had been
+directed by her navigators across California, Arizona, New Mexico,
+Texas and Louisiana until the great city of the South lay spread out
+before them. The distance covered by the airship in this flight was
+not far from thirty-five hundred miles, and the Nelson, leaving the
+coast city on Monday morning, August 7, had covered the run so as to
+reach New Orleans late Wednesday afternoon.
+
+The boys might, it is true, have speeded up and made the distance in
+thirty-six hours, or less but they realized the necessity of taking
+good care of themselves, and so they had rested in quiet places both
+Monday and Tuesday night, landing about midnight and sleeping until
+long after daylight. Having provisions with them, they had not
+found it necessary to land except when gasoline was obtained at
+Santa Fe.
+
+The machine had attracted little attention on the route, for it was
+painted a dull gray, and its aluminum motors gave forth little
+sound. It was two merits of the machine, which had been invented by
+young Leroy, that it could navigate in a clear sky a mile up without
+being observed from below, and could also run to within a short
+distance of the earth without making herself conspicuous by the
+popping of her motors. The United States authorities are now
+adapting these two qualities to the government airships to be used
+in the military service.
+
+The boys remained in New Orleans until Thursday morning, August 10,
+and then, with full provision baskets and gasoline tanks, they set
+out across the Gulf of Mexico. They soon sighted Yucatan, which is
+really a province of Mexico, darted over British Honduras, and swung
+over the forests of Guatemala, the one country in Central America
+which is never bothered with revolutions.
+
+When an ambitious person wants to wrest the reins of government from
+the officials in charge, they take him out and stand him up against
+a stone wall, with a firing squad in front. This manner of
+preventing revolutions is believed to be conducive to peace and also
+to the sanctity of human lives. Jimmie, who had been reading up on
+South and Central America while waiting in San Francisco, explained
+many points of interest as the Nelson sped on her way.
+
+They took on more gasoline at Panama, and Ned and Jimmie were very
+glad to renew their acquaintance with that now model city. Those
+who have read the former books of this series will remember that the
+Boy Scouts at one time had a commission to stand guard over the
+great Gatun dam.
+
+They did not remain long in Panama, however, as they were anxious to
+get to the scene of their future operations. They were all
+anticipating great fun in exploring "the roof of the world," which
+extends from Colombia to Argentina, north and south, through
+Equator, Peru, and Bolivia, more than 2,000 miles, or as far as from
+New York City to Denver. In many directions from this "roof" may be
+seen villages, cattle, sheep, llamas, and evidences of mining.
+
+The boys made good progress down the coast of tropical South
+America. They had heard much of Peru, and were surprised to see
+only a great strip of sand, lying like a desert, between the Pacific
+and the mountains. Now and then a little stream, fed by the melting
+snows in the Andes, comes trailing out toward the sea, but it is
+usually smaller at its mouth than at its source for the reason that
+the precious water is utilized for irrigation purposes. Wherever
+there is water crops grow luxuriantly.
+
+Thus far they had not been molested in any way. Indeed, considering
+the speed with which they had traveled, it would have been difficult
+for any one to have meddled with their plans. They were therefore
+in excellent spirits when they landed at Lima, which is the one
+large city of the country.
+
+Lima, however, is not built on the coast, Callao being the seaport
+of the metropolis. Lima is a modern city in every way, with,
+handsome streets, electric lights, and all that any modern city has
+in the way of amusements.
+
+The Nelson was anchored on the morning of August 14, in a
+sequestered spot, and the boys, after answering many foolish
+questions, laid plans to look over the wonderful city. It was
+necessary to station a strong guard about the machine, for the
+natives--many of whom spoke the English language fairly well--were
+overly curious concerning the man-made bird.
+
+In answer to all questions as to their plans, the lads replied that
+they were seeking the headwaters of the Amazon, and would soon pass
+over the Andes and drift down into Brazil. This was not far from
+the actual truth, as it really was the Intention to return home by
+that route after their mission had been accomplished.
+
+"But the wind is always from the east," was often urged against this
+plan, as explained by Jimmie, who lingered about the Nelson while
+the others were at the hotel.
+
+When it was explained to the doubters that the Nelson was capable of
+making a hundred miles an hour against a stiff breeze, the natives
+seemed to doubt the veracity of the boys. The Peruvians knew little
+of airships, and when Jimmie exhibited to them daily newspapers
+showing how Germany was building a fleet of three hundred airships
+to use in case of war, they still looked incredulous.
+
+"Look here, fellers," Jimmie explained to them, later in the
+afternoon of the arrival, as a group of curious ones stood about the
+roped-in enclosure where the Nelson lay, "I guess you don't know
+much about the navigation of the air. It used to be risky; now it
+is no more so than riding on a railroad train."
+
+"You say it well!"
+
+The words were spoken in good English, seemingly in a boy's voice,
+and Jimmie peered through his audience in order to catch a glimpse
+of the speaker. Presently, above the heads which surrounded him,
+the boy saw a hand and arm extended. The palm was out, the thumb
+and little finger flat and crossed, the three remaining fingers held
+straight out. The full salute of the Boy Scouts.
+
+"Say, you!" the lad cried out, greatly pleased at finding a Boy
+Scout there. "Where did you get that?"
+
+"Scouted for it!" was the reply.
+
+"What does it read?"
+
+"Be prepared!"
+
+"Where from?" was the next question.
+
+"Fox Patrol, Chicago."
+
+"You must be pretty foxy," Jimmie laughed, "to get away off here."
+
+The member of the Fox Patrol now made his way through the crowd and
+extended a hand to Jimmie.
+
+"You don't look as if it paid to be a Fox," laughed the latter.
+
+The boy certainly did look like a tramp. He was a lad of about
+sixteen, well formed as to figure and attractive as to feature, with
+bright blue eyes, long, fair hair, and a complexion which would have
+been perfect only for the grime upon it. He blushed as Jimmie
+looked him over, and involuntarily turned his eyes down to his
+ragged clothing and broken shoes.
+
+"Forget that!" Jimmie cried, in a moment. "I didn't mean anything
+by it. Where you stopping?"
+
+The fact was that Jimmie suspected from the appearance of the lad
+that he was hungry as well as ragged and dirty. He certainly looked
+hungry. The boy hesitated before replying, his hands deep in his
+trousers pockets, his eyes on the ground. Then a whimsical smile
+came to his face and he looked Jimmie squarely in the face.
+
+"No use of lyin' about it," he said. "I'm stoppin' down here at the
+Blue Sky Hotel. It's a dandy place to stop at. They never present
+a board bill."
+
+Jimmie sat back on the rope which was drawn about the Nelson to keep
+meddlesome ones away from the machine and burst into a roar of
+laughter. The crowd looked on stupidly, glancing from boy to boy,
+and then at one another, as if wondering if these Americans always
+went crazy when they met in a foreign land.
+
+"I know that Blue Sky Hotel," Jimmie said, presently, "though I've
+never heard it called by that name before. I had a room in one, in
+Central Park, New York, until a sparrow cop drove me out of it. I
+liked it because I didn't have to dress for dinner there," he added,
+whimsically.
+
+"The feed is rather slim," observed the other.
+
+"It's run on the European plan," grinned Jimmie. "You get your
+sleepins, an' no one cares whether you get your eatin's or not.
+What's your name?"
+
+"Dougherty--Mike Dougherty, Clark street, south of Van Buren!"
+
+"I guess you must be French," Jimmie grinned.
+
+"You've guessed it. Now, what's your name, and what are you boys
+doin' here with this old sky-ship?"
+
+"I'll tell you all about it when we get back to the hotel," Jimmie
+replied. "Do you know any of the gazabos about here? I want some
+one to watch the ginks who are watchin' the mutts who are watchin'
+the aeroplane."
+
+Dougherty laughed at this suggestion of a treble surveillance and
+pointed out a lanky looking individual who was studying the machine
+closely from the outer side of the roped-circle.
+
+"That's Pedro," he said. "He's all right. About all I've had to
+eat since I came here he's given me. He's a Peruvian Indian, and in
+need of money. Give him a dollar, and he'll guard your guards a
+month, and never leave the machine, night or day."
+
+"Does he talk United States?"
+
+"Oh, just a little."
+
+Pedro talked quite a little United States, as Jimmie called it, and
+a bargain was soon struck with him. Then the two boys started away
+together. First they visited a clothing store, where Jimmie looked
+at the best suits in stock, and measured Dougherty cautiously with
+his eyes. A full outfit of under and outer clothing provided, they
+proceeded to the hotel, where Jimmie ushered his new-found friend
+into a commodious bathroom.
+
+"Remove some of your real estate," the boy said, "an' hop into these
+new clothes. They ain't very nobby, but the best I could get here."
+
+Mike Dougherty stood looking at Jimmie for a moment as if he could
+not believe what he heard. It had been a long time since he had
+been clean and properly clothed. Then there came a suspicious
+moisture to his keen eyes and he turned away.
+
+"Oh, well," he said, with a tremble in his clear young voice, "mebbe
+I'll be able to pay you back some day. Just now I'm--"
+
+"Cut it out!" Jimmie replied. "You hain't got anythin' on me. I've
+been there meself, an' the Boy Scout that helped me out told me to
+pass it along. That's what I'm doin' now, and there's nothin' more
+to be said. When you get washed and dressed, come on to No. 4,
+that's the second room from this tub, on the left of the corridor,
+an' I'll show you the rest of the bunch."
+
+Jimmie went away to No. 4, where Ned and Sam Leroy were waiting for
+him. Somehow, it seemed to Ned that Jimmie kept him waiting about
+half the time when they were in a strange city. The little fellow
+had a way of wandering off alone and forgetting all about time in
+his delight at the strange things he saw. When he entered No. 4 he
+found Ned standing near the door.
+
+"Were you out there before?" Ned asked, pointing to the corridor, as
+Jimmie stepped inside.
+
+"Just got here," was the reply. "Found a Boy Scout from the Fox
+Patrol, Chicago, an' brought him along with me. He's washin' some
+of the Peruvian scenery off his frame, now, an' will soon be along."
+
+Then Jimmie told of his discovery of Mike Dougherty, of his leaving
+a treble guard around the Nelson, and of numerous other adventures
+in the city, which, not being in any way connected with this
+narrative, are not set down here.
+
+"I'm glad you brought this boy Mike here," Ned said, at the
+conclusion of the story. "We need some one who knows something
+about Lima to keep us posted."
+
+"About what?" asked Jimmie.
+
+"We're spotted!" Leroy cried out, before Ned could answer the
+question. "The wireless is swifter than the Nelson!"
+
+"How do you know?" demanded the little fellow. "How do you know
+we're spotted?"
+
+"Oh, Ned's been doping it out," was the reply. "He'll tell you, I
+guess."
+
+"You thought you'd take the cream off the sensation!" laughed Ned.
+"Well, that is the boy of it! All I know about it, Jimmie," he
+continued, "is that I've been receiving telegrams which simply mean
+nothing. They are from people I have never heard of, and are most
+mysteriously worded."
+
+"There's one that tells you to get out of the country," suggested
+Leroy.
+
+"Yes, but the others seem to infer that the man who sent them is out
+of his mind. The three received are from Washington, San Francisco,
+and New Orleans."
+
+"What have the messages to do with our being spotted?" asked Jimmie.
+"I don't see any connection."
+
+"Stupid!" cried Leroy. "Can't you see the wires were sent to locate
+Ned? The person who delivered them to him sure wired back that they
+had been delivered to Ned in person--in other words, that he has
+reached Lima on his journey to Paraguay."
+
+"I see!" Jimmie said, slowly. "It's clever, eh?"
+
+"Too clever," Ned said. "I don't like the looks of it. It means,
+of course, that the people who are trying to get the cattle
+concession away from Mr. Lyman have secret agents here. And that
+means that everything we do at Lima will be watched and reported."
+
+"Reported to whom?" asked Leroy.
+
+"Probably to this military person, Senor Lopez, who is on the job
+with both hands out," suggested Jimmie. "Well? What about it?"
+
+"I think," Leroy cut in, "that we'd better be getting out of this.
+They can't follow us after we get up in the air."
+
+Here a knock came on the door, and Jimmie admitted Mike and
+presented him to his chums. The boy looked trim and handsome in his
+new suit, and all took a great liking to him. While they discussed
+their plans another interruption took place, and then Jimmie saw
+Pedro at the door, beckoning excitedly to Mike Dougherty. The boy
+talked with the Indian for a short time, and then turned to Ned,
+excitement showing in his face.
+
+"He says there's another airship here," Mike said. "Prowling over
+the mountains."
+
+"They can't follow us in the air, eh?" cried Leroy. "I guess this
+is going some!"
+
+
+
+
+CHAPTER III
+
+BLACK BEARS ON THE AMAZON
+
+
+The handsome club room of the Black Bear Patrol, in the city of New
+York, was situated on the top floor of the magnificent residence of
+Attorney Bosworth, one of the leading corporation lawyers in the
+country. Jack Bosworth, the lawyer's only son, was a member of the
+Black Bear Patrol, and the club room had been fitted up at his
+request.
+
+It was in this room that Ned Nestor, Jimmie McGraw, Jack Bosworth,
+Harry Stevens, and Frank Shaw had planned their motor-boat trip down
+the Columbia river, as described in the first volume of this series.
+Jack, Harry and Frank had returned to New York from San Francisco
+when Ned had decided to accept the Secret Service mission to
+Paraguay, at the conclusion of the motor-boat vacation on the
+Columbia, leaving the two boats, the Black Bear and the Wolf, stored
+at Portland, Oregon.
+
+One evening--the evening of the 1st of August, to be exact--while
+Ned, Sam, and Jimmie were still in San Francisco, awaiting the slow
+action of the State department at Washington, Jack, Frank and Harry
+met in the club room for the purpose of "sobbing together," as they
+expressed it. They had left their friends in San Francisco
+reluctantly because of orders from home, and now they understood
+that they might have gone with Ned and Jimmie if they had only
+explained to their parents the purpose of the mission.
+
+"I suppose," Frank Shaw said, at the end of a long pause in the
+conversation, "I suppose Ned and the others are out over the Andes
+by this time."
+
+"No," replied Jack. "I heard from Jimmie by wire today, and they
+are still in Frisco, and likely to remain there nearly a week
+longer."
+
+"If the airship was only large enough!" sighed Harry.
+
+"We might still get there in time!" Frank suggested, eagerly.
+
+"The Nelson wouldn't carry us if we were there," Jack exclaimed, in
+a disgusted tone. "I wish the Black Bear had wings! Say, wouldn't
+that be a peach? We could run over to Paraguay and scare the life
+out of the boys!"
+
+"What good would it do if she had wings?" demanded Frank. "She is
+in storage at Portland, Oregon."
+
+"No," replied Harry Stevens, whose father, a noted maker of
+automobiles, had presented the motor-boats to his son, "I ordered
+the boats sent on here the day after we left the coast. We can
+take a trip up the Hudson, anyway."
+
+Jack walked thoughtfully around the room for a moment and then
+turned back to the others, looking moodily out of a window.
+
+"I've got it!" he shouted, slapping Frank on the back.
+
+"I should say you had!" remarked Frank. "What do you take for it?"
+
+"I say I've got an idea!" Jack explained, jumping up and down and
+swinging his hands over his head. "A peach of an idea!"
+
+"Does it hurt?" asked Harry.
+
+"Oh, cut out that funny stuff!" Jack cried. "When will the two
+motor-boats be here?"
+
+Harry counted on the fingers of his left hand.
+
+"We've been home two days," he said, "and we were four days getting
+to Chicago. There we laid over a day, and came on here in twenty
+hours. We are eight days from the Pacific coast. That right?"
+
+"It seems to be."
+
+"Well, then, it is seven days since I ordered the Black Bear and the
+Wolf sent on here in a special express car. They ought to be here
+now."
+
+"Then," shouted Jack, pulling Harry around the room, "we're all
+right--fit as a brass band at a free lunch! Whoo-pee!"
+
+"It must be hungry," Frank exclaimed, regarding Jack with seeming
+terror. "Does it ever bite when it puts out these signals of
+distress?"
+
+"Don't get too funny!" Jack warned.
+
+"Then loosen up on this alleged idea!" Frank replied.
+
+Jack rushed across the room and brought out an atlas of the world,
+which he dumped on the floor and opened.
+
+"Look here, fellows!" he said, squatting over the map of South
+America, his chin almost on his knees.
+
+"We're looking," grinned Frank. "What about it?"
+
+"Here we are in New York," Jack went on. "Here they are in San
+Francisco. Now, they've got to sail to Paraguay, which is just
+about twice as far from San Francisco as is New York. Anyway,
+that's the way it looks on the map."
+
+"It is all of that distance," Harry put in.
+
+"Well," Jack continued, "as I said before, here we are in New York,
+with the mouth of the Amazon river about as far away as San
+Francisco, perhaps a little farther."
+
+"Well?" demanded Harry.
+
+"I begin to see the point!" Frank admitted. "But will the folks
+stand for it?"
+
+"Mine will," Harry answered. "Dad didn't make the Black Bear to lie
+in storage. He'll stand for it, all right."
+
+"So will mine," Frank said, then. "I'll tell him I'll send him a
+lot of news for his paper."
+
+Frank's father was owner and editor of the Planet, one of the
+leading morning newspapers in the big city, and it was always a
+fiction of the boy's that he was going out in the interest of the
+paper when he wandered off on a trip with the Boy Scouts.
+
+"I'm afraid you can't make that work again," laughed Jack. "Ned
+says that you sent only four postal cards and six letters back from
+Panama."
+
+"Well, wasn't that going some?" asked Frank.
+
+"Of course, only Ned says the postal cards carried the
+correspondence for the Planet, and the letters carried requests for
+more money!"
+
+"Anyway," Frank insisted, "Dad will stand for it. What is it?"
+
+"Well," Jack went on, "I'm sure my Dad will let me go. He wants me
+to go about all I can. Says it brightens a fellow to rub up against
+the rough places of the world."
+
+"There's rough corners enough in South America," laughed Harry.
+
+"Now, let us get down to figures," Jack continued. "We ought to be
+able to get to the mouth of the Amazon on a fast boat, with the
+Black Bear and the Wolf on board, in a week or ten days-say ten
+days. About that time they will be getting into Paraguay. What do
+you think of it?"
+
+"Fine!" cried Harry.
+
+"The best ever!" Frank responded. "But what then? We can't run up
+to Paraguay in the Black Bear."
+
+"We can get away up in the Andes," answered Jack, with the map of
+Brazil before him. "See these crooked little lines? Well, those
+are rivers. Just see how far we can go in a motor boat."
+
+"But that won't bring us to the aeroplane," Frank objected.
+
+"Yes, it will," Harry answered. "They are coming back by way of the
+Amazon valley, and we can't miss them. Oh, what's the use? Suppose
+we begin packing?"
+
+"Well, I don't know exactly what we are to do after we get up the
+Amazon," Harry laughed, "but I'm game to go. There are head-hunters
+and cannibals up there, and we may find a little amusement."
+
+"We're going after Ned and Jimmie," Jack explained. "This is a
+relief expedition! After they get to Paraguay they'll snatch that
+Lyman person out of the cold, damp dungeon keep he is supposed to be
+in and then sail off over the Amazon valley. There's where we catch
+up with them. Do you suppose we can find a ship going to the mouth
+of the Amazon early in the morning?"
+
+"You certainly are fierce when you get started!" laughed Harry.
+"Well," he added, "you can't get ready any too soon to please me."
+
+It was two days before the boys found a vessel going their way, and
+even then Jack insisted that his father bribed the owners to run off
+their course in order to set the boys and their motorboats down at
+the mouth of the Amazon river. The boat, however, was a fast one,
+equal in speed to a modern ocean liner; and in ten days from the
+time of starting from New York--on the 12th of August--the boys were
+stemming the current of the great river--more like a shoreless sea
+there at the mouth than a river!
+
+"Huh!" Frank exclaimed, as they left the island of Joannes to the
+south, "this is no river! It is a blooming sea!"
+
+"Pretty near three hundred miles wide at the delta, including that
+big island," Harry said. "It is some river, eh?"
+
+"Four thousand miles long!" Jack contributed. "It is navigable for
+commercial purposes for 2,200 miles, and our boats can go up clear
+to the foot of the Andes."
+
+"Boats went there in the days of Columbus," Frank said. "A
+companion of Columbus first discovered this great delta. The river
+fertilizes two million square miles of territory, and is the
+greatest water system in the world."
+
+"Why," Harry observed, desiring to contribute something startling to
+the discussion of the river, "the current is so strong that it
+carries fresh water and sand five hundred miles out into the
+Atlantic Ocean. It is just a fresh water river in a salt water sea
+for five hundred miles!"
+
+That night the boys kept the engines of the Black Bear going, one
+remaining on watch all through the dark hours. They had plenty of
+gasoline in the tank, and the tender, the Wolf, was carrying a load
+of fuel which Jack declared would last them until the end of the
+year!
+
+It may be well to state here that the Black Bear, the Boy Scout
+motorboat, was a specially constructed vessel, built by Harry's
+father for river work. The materials were light yet strong, and the
+boat could easily be taken apart and put together again when
+occasion required. Between the cross-grained slices of tough wood
+of which the craft was built were plates of steel, thus rendering
+the boat virtually bullet proof.
+
+The Black Bear was constructed so that it could be almost entirely
+thrown open to the sunshine when so desired or closed tightly
+against cold or rain. The roof could be rolled up in a bundle in
+the middle like the curtain of a modern desk. The sides were
+composed of oblong panels which could be inserted in grooved steel
+uprights when it was desired to close in the interior of the boat.
+The motors were very powerful.
+
+In fact, it was just such a boat as was needed on the trip the boys
+had in mind. It had done excellent service on the Columbia, and
+nothing less could be expected of it on the Amazon. The Wolf, which
+was merely a tender, was watertight in construction, being shaped
+like a banana, and was towed by the motor-boat. Here the extra
+stocks of gasoline, provisions, and ammunition were packed. The
+interior of the Wolf was about six feet by eighteen in size, while
+the distance from rounded floor to convex roof was about four feet.
+
+On both sides of the interior were gasoline tanks, which also
+extended under the floor, lifting the bottom of the interior space
+three feet. Above the tanks were spaces for provisions and
+ammunition. The space between the tanks and the lockers was about
+two feet, and here one might ride in comfort, after getting used to
+the rolling of the boat. There were tight glass panels of thick
+plate glass at the ends and the top.
+
+Ventilators and loopholes, controlled by wires from the center, were
+cut in the ends and protected by sliding covers. Lying in the
+passageway, one might look out at either end, and shoot out, too, if
+occasion required. When fully loaded, the Wolf was submerged about
+half its height. On the top was a staff from which floated an
+American flag. The boys were very proud of the Wolf, and Jimmie had
+often declared, on the Columbia river trip, that he would some day
+take an exciting ride in it.
+
+During their passage up the river the boys were often hailed from
+passing craft, but they took little heed, as they did not care to
+lose time gratifying the curiosity of those they met. Indeed, if
+they had stopped to talk with all who hailed them, they would have
+made slow progress. Up to about sixty years ago the Amazon was
+closed to all save Brazilian vessels, but now it is open to the
+commerce of the world.
+
+There are now vessels coming from and going to all parts of Europe
+and America from Amazon ports. There are lines of great steamers on
+the main stream, lines of smaller steamers on the big tributaries,
+and launches and small craft of all sizes on the affluent branches.
+Often the passing ships, steamers, launches, etc., almost took the
+form of a procession on the lower waters.
+
+Everywhere the smaller ships were gathering the products of the
+great Amazon basin-rubber, cocoanuts, hardwoods, dyewoods, pelts,
+tropical fruits and other commodities. Every year over three
+million tons of products come down the great river. The Amazon
+drains a country as large as the United States east of the
+Mississippi. Its feeders reach the Andes, draining watersheds
+within a hundred miles of the Pacific ocean. It has tributaries
+fifteen hundred miles long.
+
+It did not take the Black Bear very long to pass the green islands
+near the delta. The river there looks like an ocean. In fact, the
+main branch of the Amazon is from fifty miles to two hundred miles
+in width. Some of the tributaries are a hundred miles wide. It is
+from fifty to two hundred feet deep. The water is always dark
+colored because of the wash brought down from the uplands. For a
+long time it did not seem possible to the boys that they were
+sailing on a river instead of an ocean.
+
+"Ned and the boys must be over Paraguay now," Jack said, one day,
+after they had been on the river nearly a week without accident or
+important incident of any kind.
+
+"Yes," Frank replied, "they must be there by this time. Jimmie said
+they were to leave San Francisco on the 7th, or about that time. It
+would take a week or more to get to Lima, for they couldn't remain
+in the air long at a time, and the resting spells would set them
+back a little. Suppose they got to Lima on the 14th, which was last
+Monday, they could rest up and go prowling over that dirty little
+republic--which is not a republic at all, but a despotism tempered
+by revolution."
+
+"I'd like to know just what course Ned has decided on," Harry said.
+"I don't see how he's going to get to Mr. Lyman."
+
+"He'll find a way," Jack insisted. "He always has, and he always
+will."
+
+It will be seen that the boys were tolerably accurate in their
+estimates of the speed of the Nelson. On the day they were
+discussing the possible location of the big airship, which was the
+18th of August, the Nelson was in the center of as pretty a muss as
+Ned had ever mixed with.
+
+The boys in the Black Bear put on all speed, traveling nights as
+well as days, and before long began watching the heavens, for an
+aeroplane. But the lads on the Nelson were not looking for a boat
+poking her nose toward the Andes--"a relief expedition," as Jack
+called it!
+
+
+
+
+CHAPTER IV
+
+A CHASE IN THE NIGHT
+
+
+Following the excited announcement by Mike that an airship was
+prowling about over the mountains and Leroy's sudden cry of
+exultation at the prospect of a struggle for supremacy above the
+clouds, there was for a moment absolute silence in the hotel room
+where the boys stood. Finally Pedro entered and closed the door.
+
+Ned walked to a window and looked out. The day was fading, and
+already the feet of the distant mountains were wrapped in purple
+twilight. The window faced the north, giving a fair view of the
+city and the Andes as they strung along in that direction, looking
+like a chain of bald heads lifting from the obscurity of a fog. The
+airship was not in sight from where he stood.
+
+Pedro saw what he was looking for and stepped to his side, one hand
+pointing off to the east.
+
+"Out there!" he said.
+
+"When did you first see it?" asked Leroy, not waiting for Ned to
+conduct the cross-examination.
+
+The Indian talked with Mike for a moment.
+
+The latter did not seem to understand all that was said to him, but
+presently he turned to Ned.
+
+"He says he saw it only a minute before he came here," he explained.
+"He says a lot more that I can't understand. I've been here only a
+month, and I'm not quick at learning new speech."
+
+"Ask him if he knows whether she landed anywhere near the city," Ned
+directed.
+
+The Indian did not know. The airship was over the mountains when he
+first saw it, and that was all he could say about it.
+
+"Do you think we've been followed down here?" asked Jimmie.
+
+"Of course!" Leroy broke in. "What else would an airship be here
+for just at this time? And if she wasn't sneaking about after us,
+what would she be hanging up there in the sky for? Why doesn't she
+come down to town, like we did?"
+
+"It may be that the arrival of this airship just at this time is a
+coincidence," Ned said, "but it seems to me that there is something
+significant about it. I have felt all along that we were not yet
+rid of the rascals who tried to make us trouble at San Francisco."
+
+"Some one must want the cattle concession that Lyman has pretty
+badly," Leroy ventured. "Well, we'll, have to run away from them, I
+take it!"
+
+"Then how are we going to find out where this Lyman person is?"
+demanded Jimmie. "No, Sir!" he went on, rubbing his freckled nose
+in meditation. "We've just naturally got to bust 'em up!"
+
+The proposition was indeed a serious one. If the airship was really
+there to take note of the activities of the boys on the Nelson, the
+situation could hardly be improved by following either line of
+conduct suggested by the boys.
+
+Nothing could be gained by "running away" from the unwelcome
+visitor. Nothing was to be gained by following the advice to "bust
+'em up." A race would only serve to draw the Nelson away from the
+point of action, away from the place where Lyman was held in
+captivity. To "bust 'em up" would be to set all the official rings
+of Paraguay in operation against the lads, place the Boy Scouts
+under the ban of the law!
+
+"If we only knew just where to find this Lyman person," Jimmie went
+on, "we might swoop down an' get him an' give the lobsters a run for
+their money."
+
+"Perhaps," Ned suggested, "we'd better wait for this new navigator
+of the air to show us where he is."
+
+"I see him doing it!" cried Leroy.
+
+"You bet he will!" Jimmie cut in. "He'll hang around the point of
+danger! He'll show us where the man is by standing guard over him!
+What?"
+
+"That's my idea," Ned replied, "still, he may devote his energies to
+keeping track of us. One can never tell what an enemy will do."
+
+"Well," Leroy said, "I'm going back to the Nelson. There's a chance
+of the lobster dropping down and trying to cripple her."
+
+"A very good idea," Ned agreed.
+
+Jimmie and Mike hastened away with Leroy, but Pedro remained at the
+request of Ned. A plan for meeting the emergency was already
+forming in the active brain of the Boy Scout, and an important
+detail depended on information which the Indian might be able to
+give.
+
+Before opening the question, however, Ned, motioning to the Indian
+to follow, made his way to the flat roof of the hotel building.
+There he found several men, smoking, chatting, and watching the
+airship, now almost directly over the city. In Peru many houses are
+built with especial reference to providing a lounging place on the
+roof.
+
+It was growing darker, and the lights of the airship shone brightly
+against the dimming sky. The aviator was now circling around the
+city, dropping lower at times, then skimming in spirals to a higher
+point. While Ned stood watching the machine, realizing that the
+fellow in charge was no novice in aviation, a gentleman whom he had
+noticed three times before that day observing him closely advanced
+and stood by his side. He was a well dressed, clean-shaven man of
+perhaps thirty, with an intelligent face, a bustling manner, and a
+suit of clothes which Jimmie would have described as "loud enough to
+lead a circus parade."
+
+"Evidently an American commercial traveler," Ned thought, as the
+stranger stood by his side a moment without speaking, his eyes fixed
+on the airship.
+
+"She goes some, eh?" the stranger observed, presently.
+
+"The aviator seems to know his business," Ned admitted.
+
+"You came in an aeroplane yourself, didn't you?" asked the other.
+
+Ned answered in the affirmative.
+
+"Thought so," the other went on. "Hadn't seen you about the city
+until this afternoon, and some one said you came in an airship.
+Where from?"
+
+"New York," Ned replied, half amused at the impertinence of the
+question.
+
+"Good old town!" the other exclaimed. "Hot old town! I like it.
+There's something always going on there. I'm from New York myself,
+but I'm selling goods for a Chicago firm--steam pumps! I've got the
+best steam pump in seven countries! Came here to sell to a mining
+company. Nothing doing. What's your name? Mine is Thomas Q.
+Collins."
+
+"Nestor," Ned replied, shortly.
+
+"And you're out for fun?"
+
+"That's the idea." Ned did not think it necessary to enter into
+details.
+
+"Hope you get all that's coming to you! Say, will you give me a
+ride in that machine of yours? I went out to see it today. Looks
+to me like it could knock the spots off anything of the kind in the
+world. I don't know anything about airships, but I do know about
+steam pumps, and also about machinery. I know a good piece of work
+when I see it. That boat of yours is a peach!"
+
+"It isn't my machine," Ned replied, "but if we remain here over
+tomorrow I'll see about granting your request."
+
+The two talked for a moment longer, and then Collins left the roof.
+Later, Ned saw him moving through the street below in the direction
+of the place where the Nelson had been left. The boy hardly knew
+what to make of Collins. He might be a steam pump salesman, just as
+he had described himself, and, again, he might be a spy sent out by
+Lyman's enemies to discover the plans of the Boy Scouts--even to
+wreck the Nelson if possible. He decided to, if possible, learn
+something of the fellow before taking him on board the aeroplane.
+
+After a time the strange airship fluttered away to the north and
+then Ned and Pedro descended to the former's room. Sitting at the
+north window, the two could see the lights of the aeroplane dropping
+downward, and they concluded that the aviator was seeking a resting
+place for the night.
+
+"He's going to bed in Inca Valley," Pedro said, watching the
+descending bird. "It is a good place to hide the machine."
+
+The words were spoken in pretty good Spanish, and Ned turned quickly
+and asked:
+
+"You speak Spanish then?"
+
+The question was asked in Spanish, and the Indian's face brightened.
+
+"Yes," he said, "but I never suspected that you knew the language."
+
+"Only a smattering of it," laughed Ned, "but, still, I think you can
+understand what I say to you. As I want you to do most of the
+talking, we may get on very well together."
+
+"What do you want to know?" asked Pedro.
+
+"First, I want you, after we have had our talk, to go out into the
+city and find out, if you can, all about that aeroplane. I want to
+know if it has ever been seen here before, if the aviator comes to
+the city after descending, if he is a stranger here--all about him,
+in fact."
+
+The Indian bowed.
+
+"Then," Ned went on, "I want you to find out whether the machine is
+well guarded. I also want to know what kind of a machine it is, and
+where it came from. If you think it advisable I want you to get
+into conversation with the aviator and see what kind of a chap he
+is."
+
+Another bow from the Indian, whose face expressed pleasure at the
+prospective employment. Ned pondered for a moment, as if not quite
+certain of his ground, and then asked:
+
+"How, well are you acquainted with the country lying between Lima
+and Asuncion?"
+
+"Oh," was the astonished reply, "but that is a long, long
+distance--two, three thousand miles."
+
+"Yes, I know, but have you ever been over the Andes?"
+
+"Oh, yes. I am a guide."
+
+Ned pondered a moment.
+
+"How far east and south?" he asked, then.
+
+"To Lake Titicaca."
+
+"That is on the boundary between Peru and Bolivia?"
+
+"Yes."
+
+"And you know that country--the country around the lake?"
+
+"Very well, indeed."
+
+"It is a long way from Asuncion?"
+
+"It is barely a third of the way. You will see on the map."
+
+"Well," Ned said, after a short silence, "I may as well tell you
+what I want. I want to be directed to a place in the mountains
+where I can securely hide our aeroplane. It must be a hiding place
+absolutely out of sight, especially from the sky. Do you
+understand?"
+
+The Indian nodded, a knowing smile on his dusky face.
+
+"You mean to hide from the other airship?" he asked.
+
+"Yes."
+
+"There are caverns near Lake Titicaca."
+
+"So I understand. Caverns which defy exploration. But, you see, I
+must have a hiding place from which the airship can be brought out
+with speed and returned in the same way."
+
+"To dodge out and in? Yes, I comprehend."
+
+The two dwelt over the maps and plans until; Leroy and Jimmie came
+romping in to report that all was quiet at the machine, and that
+Mike was to remain on guard until midnight, when Jimmie was to
+relieve him. Then Pedro went out in the city to listen to such talk
+of the strange airship as was floating about the streets. He was
+back in a couple of hours with the information that the airship had
+not landed in the city, and that it had never been seen there
+before.
+
+"It seems to me," Ned said after the Indian ceased speaking, "that
+now is our time. We ought to be a long way from Lima before dawn."
+
+"The other fellow'll see us!" Leroy objected.
+
+"We'll have to chance that," Ned replied. "We needn't have any
+lights you know, and the motors make very little noise. Get your
+traps ready, boys!"
+
+It was arranged that Pedro was to remain, under pay, in Lima,
+storing up such information as he could secure against the day of
+the return of the Nelson. Mike was to remain with him, of course,
+as there would be no room on the Nelson for him. The young man when
+told of the plans, objected strenuously to being left, but was
+finally consoled by the promise that the aeroplane would be sent
+back after him when opportunity offered.
+
+It was after midnight when all the arrangements were made and the
+boys passed out of their rooms into the hotel lobby. At that hour
+they thought the driver of the other aeroplane would be likely to be
+sleeping. At the very door of the hotel they came upon Mr. Thomas
+Q. Collins! He strolled up as Ned stepped into the doorway and
+extended his hand. Ned took it, gave it a perfunctory grasp, and
+attempted to paw on.
+
+"If you don't mind," Collins said, with a persuasive mile, "I'll
+walk with you if you are going out to your aeroplane. I've been to
+bed and find that I can't sleep."
+
+"All right," Ned replied, thinking that he would rather have the man
+with him than on his way to report the departure of the Nelson. "We
+are just going to look the ship over--perhaps take a little spin.
+Come along."
+
+"I should like very much to go with you, in case you decide to go
+sailing tonight," Collins said. "Perhaps you may be able to arrange
+it?"
+
+"I'm afraid not tonight," Ned replied, wondering just what this new
+acquaintance was up to. "However," he added, "you may as well come
+along and look over the ship."
+
+Collins seemed glad of even this slight concession on the part of
+the boy, and walked along briskly. Presently, however, he began to
+fall back, talking with Jimmie, who was a few paces behind. Then,
+before very long, the little fellow missed Collins. He had
+disappeared in a dark alley. Ned worried over this when informed of
+the fellow's strange and contradictory conduct. The man might have
+gone to make report to the other aviator! This was not a pleasant
+reflection.
+
+Mike was found sitting in front of the Nelson, talking with a native
+who was trying to learn all about an aeroplane from, a boy who knew
+nothing about it himself! It took only a short time to make ready
+for flight, then the Nelson was up and away, making little noise as
+she cut the air, her great planes flashing in the light of the moon.
+
+"This is pretty poor, I guess!" Leroy exclaimed, glancing over the
+mighty map of sea and plain and mountain. "How fast do you want to
+go?"
+
+"At full speed," Ned replied.
+
+"I should say it would be full speed!" Jimmie said, half covering
+his mouth with his hand, to keep his words from being blown back
+down his throat. "That is," he added, "if you want to make a
+sneak!"
+
+Ned turned away to the north and saw the white planes of the strange
+aeroplane gleaming in the moonlight. She seemed to stand still for
+an instant, and then sped off to the southeast. Ned sighed with
+apprehension, but Leroy laughed.
+
+"Come along, you!" he cried, looking back. "If you want a race,
+come on, and I'll give you the run of your life!"
+
+
+
+
+
+CHAPTER V
+
+JIMMIE TAKES A RUN IN THE AIR
+
+
+The white aeroplane flashed by, going farther to the east, and Ned
+laid a hand on Leroy's arm as he was about to increase speed.
+
+"Don't hurry," he said, almost screaming the words into the boy's
+ear.
+
+"I don't want him to beat me!" the driver called back.
+
+"Let him go," Ned commanded. "Play about the scenery a little
+while, and then we'll go back to Lima."
+
+"Let me catch him!" pleaded Leroy. "Just let me chase around him a
+couple of times. I want to see him make a sneak when he sees the
+Nelson in action!"
+
+"Can you do it?" asked Ned.
+
+"Sure I can do it. Just give me a chance. There isn't a machine in
+the world that can win a race against the Nelson!"
+
+"I'm sure of that," Ned answered, "and I hope that fellow over there
+won't find it out right away. Let him think he can go by us like we
+were tied to a cloud, if he wants to. There will come a time when
+his confidence in his machine will cost him his job!"
+
+Leroy saw that Ned was really in earnest in the expressed wish to
+deceive the aviator of the rival aeroplane, and also saw that there
+was good reason for doing so, so he shut off the motors and started
+to volplane downward.
+
+"No," Ned said, "that's not right. Make him think we're trying to
+catch him. Give him the impression that we want to overhaul him,
+but haven't the speed."
+
+"The Nelson will blush red with shame to be bested by a water wagon
+like that!" Leroy grumbled, but he did as requested.
+
+The white aeroplane's driver appeared to take the bait. He
+loitered, as if waiting for the Nelson to come up, then circled away
+from her in great wide swaths. Once he swept around the Nelson, and
+Leroy almost shed tears of chagrin.
+
+"Just see him!" the boy wailed. "He thinks I've got a dirt cart
+here! He is putting it all over me! I can go two miles to his one,
+and yet I'm taking all his guff! Let me get at him! I'll run him
+down!"
+
+In a short time the stranger, apparently satisfied that he could
+outfly the Nelson, should he desire to do so, moved off to the south
+and soon disappeared in the distance.
+
+"Now what?" asked Leroy, half angrily.
+
+"He'll watch for us," Ned replied, "but he won't find us chasing
+him. Go through some of your flip-flaps and then go back toward
+Lima. I want to say a few words to that Mr. Thomas Q. Collins."
+
+Half mollified at the thought of getting a little speed out of the
+Nelson, Leroy drove straight for the zenith. Up, up, up he went,
+onward toward the stars, shining no brighter for his approach, yet
+luring him on. All the world below was flooded with moonlight and
+starlight. The mountains were dim in spots, where higher peaks
+dominated the light, the Pacific shone in the radiance of the night.
+The blue dome of heaven rounded away like a precious bowl set with
+diamonds.
+
+The roofs of Lima drew closer together, apparently, and the whole
+town looked like a little cluttered point of land. And the
+mountains and the sea stretched away endlessly, and earth took on
+the look of a great rug woven with invisible stripes. Up, up, up,
+until the air became thin and the lungs staggered for breath.
+
+Then the motors were shut off and the ocean and the mountain chains
+seemed to rise up to meet the aeroplane, sailing at the speed of
+the, fastest express. Over the water and down until even Jimmie
+clutched Ned's arm and gave forth an exclamation of alarm. Then a
+turn of a lever sent the Nelson skimming over Calleo and back toward
+Lima. Avoiding the vacant space where the Nelson had rested before,
+Leroy, under Ned's directions, landed on the dry sand some distance
+away.
+
+"Of course that other chap will find us when he comes back," Ned
+said, when the boys stood on solid ground again, "but we'll try to
+make him think we're hanging around Peru just for the fun of it."
+
+"Perhaps he won't come back," suggested Leroy. "Then I'll lose my
+chance of showing him what the Nelson can do."
+
+"I have an idea that he'll be back by morning," Ned replied.
+
+In this the boy was right, for the white aeroplane showed in a
+couple of hours, just about dawn, circled around the city, hovered
+for a moment over the Nelson, and then went off to the north again.
+
+"It is a certainty that she is here to butt into our game!" Jimmie
+said, as the white planes disappeared. "She'll start when we start,
+an' stop when we stop, an' there won't be any getting away from her.
+How does she get into the air so quick after we cut loose? That's
+what I'd like to know."
+
+"Some system of signals, undoubtedly," Ned answered. "Now," he
+continued, "we'll cuddle up in our blankets here and sleep as long
+as the natives will let us. Who'll keep awake?"
+
+Each one wanted to be the one to stand guard, but the point was
+decided by the appearance of Mike and Pedro, who had watched the
+maneuvers of the Nelson, had noted her landing place, and hastened
+forward. Thus relieved of the care of the machine, the three boys
+hastened to the hotel and were soon sound asleep.
+
+It was noon when Ned awoke, brought out of a deep slumber by an
+impatient knocking at his door. He was out of bed in an instant
+and, clad only in his pajamas, opened the door and looked out. Mr.
+Thomas Q. Collins stood in the corridor with a look of alarm on his
+face.
+
+"Thought I'd never get you out," he said, stepping, uninvited, into
+the room and taking a chair. "Thought that you ought to know what's
+been going on."
+
+Ned had little confidence in Collins. The fellow's strange conduct
+of the night before naturally made the boy suspicious. After
+requesting a ride in the Nelson, or, at least, the company of the
+Boy Scouts to the place where the machine had been left, he had
+disappeared without a word of explanation.
+
+It seemed to Ned that he had good grounds for the belief that
+Collins had spied around until he had learned that the aeroplane was
+going up, and had then communicated the information to the man on
+the white machine. At least, the strange aviator had shown in the
+air directly after the disappearance of Collins.
+
+But it was no part of Ned's purpose to permit Collins to see that he
+was suspected. It was rather his idea to keep on good terms with
+the fellow and watch him for any evidences of treachery. He
+therefore greeted him cordially and asked:
+
+"Something interesting going on in the city? We did not return
+until nearly dawn, and I've been asleep ever since."
+
+"You haven't heard about the attack on our aeroplane, then?" asked
+Collins, looking Ned over keenly.
+
+The boy tried not to exhibit the least emotion or excitement at the
+disturbing question. Leaning back in the chair he had taken, he
+asked:
+
+"The curiosity of the people got the better of their courtesy, eh?
+I have been afraid of that. Well, I hope the Nelson was not
+seriously injured."
+
+Thomas Q. Collins had the appearance of one who had expected to
+unwrap a great sensation and had failed. His face was a study.
+
+"Well, no," he replied. "The fact is, when the rush was made the
+aeroplane shot up into the air."
+
+"Then one of the boys must have been there," Ned said, calmly,
+although his heart was beating like a drum.
+
+"The little fellow was there, the one you call Jimmie," was the
+reply.
+
+"And he went into the air alone?"
+
+"No; at the last minute a Peruvian Indian who has been hanging about
+the machine ever since you came here went with him."
+
+"Then there is no danger," Ned replied, really feeling relieved at
+the thought that Jimmie was not alone in the aeroplane. "The lad
+will bring the Nelson back in good time. Anyway, he is entitled to
+a little excursion, 'all by his lonely,' as he puts it."
+
+"He can operate the machine?"
+
+"Certainly. He can handle the Nelson easily."
+
+Thomas Q. Collins regarded Ned steadily for a moment, his brusque,
+salesmanship manner all gone, and then asked:
+
+"'Where are you going from here?"
+
+The fellow was showing his hand at last! Or was this just natural
+curiosity? At that moment Ned was more interested in discovering
+something about the attack on the Nelson than in fighting off
+personal and impertinent questions, so he said:
+
+"We haven't made up our minds as to our future course. By the way,
+what was the cause of the attack on the aeroplane?"
+
+"Oh," replied Collins, frowning slightly, "there were a lot of
+people gathered about the ropes, and one of your guards was a little
+coarse in protecting your property, and there was a blow struck,
+then the mob rushed the roped-in enclosure. I think there was no
+one seriously injured."
+
+"I wonder if the other aviator is also having trouble with his
+machine?" asked Ned, anxious to know what Collins would say about
+the white aeroplane.
+
+"I don't know about that," Collins replied. "In fact, the other
+fellow went off to the south soon after the departure of the
+Nelson."
+
+"Chased Jimmie up, eh?"
+
+"Well, anxious for a race, it seemed to me."
+
+"Has the Nelson returned?" asked Ned, then.
+
+Collins shook his head.
+
+"If you'll excuse me, then," Ned said, presently. "I'll dress and
+take breakfast and go down to see what's doing."
+
+"Your breakfast will be luncheon, I guess," laughed Collins. "I was
+on my way to the dining room when I thought of you. If you don't
+mind I'll wait for you in the lobby. These natives are not very
+good table companions. I'm sick for the sight of my own countrymen,
+anyway, and I can't tell you how glad I am to see you here."
+
+Collins went out and closed the door and Ned set about his toilet.
+He did not know what to make of the alleged steam pump salesman. At
+times he appeared to be perfectly frank and honest, then there would
+come to his eyes a look of half-concealed cunning and greed which
+put the boy on his guard.
+
+However, Ned thought, the correct way to fathom the fellow's
+intentions would be to remain in his company as much as possible.
+So the boy bathed and dressed and went down to Collins in the lobby
+with a cheerful face.
+
+During the meal Collins talked incessantly of the country and his
+prospects in South America. Ned listened, saying little, even in
+the short spaces of silence. He was waiting for the fellow to
+strike some chord which tuned with his actions of the night before.
+At last it came.
+
+"I'm thinking of going over to Asuncion," he said, when the meal was
+nearly over. "There are mines over that way, and I may stand a
+chance of selling a pump. Rotten luck in Peru, and I can't afford
+to spend all this expense money and not sell a thing. I hear that
+there are a few Americans over in Paraguay," he added, tentatively,
+smiling over at Ned.
+
+"I know very little about the country," Ned said, coolly, fearful
+that Collins would drop that line of conversation, "and I never
+heard that foreigners of any sort were made welcome in Paraguay. I
+don't think we'll go out of our way any to visit that hot little
+republic."
+
+Collins looked disappointed. Ned could see that. In a moment he
+tried again to bring the subject out, but Ned seemed entirely
+indifferent.
+
+When the two left the hotel and walked in the direction of the sand
+lot where the Nelson had been left, the boy was fully satisfied that
+Collins was in league with his enemies. For all he knew, the fellow
+might be the very man who was trying to get Lyman's concession away
+from him. This might be the man who was bribing the crooked
+military chief to make it impossible for the cattle man to carry out
+his contract.
+
+"What time did the Nelson leave?" Ned asked, as they drew near a
+little group of natives standing on the sand lot.
+
+"Not far from nine," was the reply.
+
+"I didn't think Jimmie would be out that early," laughed Ned. "He
+is a little sleepy head, ordinarily."
+
+Pushing their way into the center of the little crowd, Ned and
+Collins found Leroy and Mike Dougherty engaged in a heated debate
+with a police officer who was threatening arrest. Ned stepped back
+so as not to attract the attention of the boys, and kept his eyes
+fixed on Collins. In a moment he saw that gentleman give an
+impatient gesture which seemed to urge the officer on.
+
+Ned thought fast for a moment. He was considering whether or not he
+had been brought there for the purpose of getting into a row in defense
+of his chums and being arrested with them. He was heartily glad that
+the Nelson was out of the way, although he would have been better
+pleased had he been safe aboard of her.
+
+"These Peruvian officers are too fresh!" Collins said, in a moment.
+"What do you mean by molesting these boys?" he added, in Spanish,
+turning to the officer.
+
+"They are charged with assault," the latter replied.
+
+"By whom?" asked Ned, also speaking in Spanish.
+
+"They struck half a dozen citizens," was the indefinite reply. "We
+must take them to jail."
+
+"I'll give you a bump in the eye if you come near me!" Leroy put in,
+as he searched the sky eagerly for some sign of the Nelson.
+
+"That wouldn't help matters any," Ned said, speaking in English.
+"Go along with the officer, and I'll pay your fine."
+
+Collins looked annoyed at this cautious advice. He came nearer to
+Ned and whispered:
+
+"The courts are slow and uncertain here. It may be weeks before the
+boys will be restored to liberty if they are locked up. If we could
+get them away into the mountains until the Nelson returns that would
+end the whole affair."
+
+"And so you want to get me mixed up in it, too!" thought Ned, as the
+officer glared at him. "You want to get me on a charge of resisting
+arrest! When we get out of here, Mr. Thomas Q. Collins, I'll see
+that you get what's coming to you!"
+
+If Collins could have known what was passing in Ned's mind, could
+have understood how suspicious the boy was of him, he would not have
+urged the lads, in English, to cut and run. By doing so he merely
+confirmed Ned's unfavorable opinion of him. From that moment Ned
+knew him for what he was, and resolved to get him out of the way in
+some manner.
+
+Leroy and Mike paid little attention to what Collins said, as a
+shake of the head from Ned gave them to understand what was passing
+in his mind. In a moment Ned stepped to the side of the policeman.
+
+"You are all right, officer," he said. "You are only doing your
+duty. The boys will go with you, and I'll pay their fines."
+
+But, as Ned discovered, it is easier to get into jail in Peru than
+it is to get out.
+
+
+
+
+CHAPTER VI
+
+NED IS GUILTY OF LARCENY
+
+
+Night came on and no Nelson showed in the sky. Ned wandered
+restlessly about the rather handsome city, anxious for the aeroplane
+as well as for the boys who were in the city prison. Collins was
+always with him, at first, expressing sympathy and suggesting plans
+for getting the prisoners out on bail. The complainant in the case,
+it was claimed by the officers, was too badly injured to appear in
+court.
+
+Ned grew sick of the constant talking of the fellow at last, and
+went to his room, saying that he was due for a little sleep. But
+the boy, as may well be imagined, did not sleep. Instead, he sat by
+his window watching the sky.
+
+Where had Jimmie gone with the machine? This question was always in
+his mind. Had he met with an accident and was he lying, crushed
+from a long fall, in some mountain canyon? Had the pursuing
+aeroplane overtaken him and destroyed or captured the Nelson?
+
+It was not like the little fellow to disappear so utterly. Even
+supposing he was afraid to return to Lima, he ought to understand
+how anxious his friends would be and signal them from the upper air.
+Surely, Ned reasoned, this would be safe, for the hostile machine
+could not approach the Nelson in speed, and, after giving a
+reassuring signal, the boy could disappear in the mountains again.
+
+It was dark now in the room where Ned was, and he sat looking out at
+the sky in the hope of seeing the welcome lights of the aeroplane.
+Presently, he saw a flicker of light off to the east. It increased
+in size rapidly, and Ned knew that it was an airship he saw
+approaching at wonderful speed, but he had no means of knowing
+whether it was Jimmie on the Nelson or the hostile aviator.
+
+If it was Jimmie, he thought, there would be a signal directly. He
+waited eagerly, but no signal showed. Presently the airship drifted
+off to the north, and Ned saw the glint of moonlight on white
+planes. It was the hostile ship, sure enough, but why had she
+abandoned pursuit of the Nelson?
+
+Ned resolved to secure a closer view of the airship, but the next
+question was how to avoid Collins, who was at that moment pacing to
+and fro in front of the hotel. The alleged salesman would be apt to
+accost him as soon as he appeared and insist on going with him.
+
+He had had enough of Collins. He had no doubt that the fellow was
+in the conspiracy against him. It seemed reasonable that he had
+been warned by wire of the approach of the Boy Scouts, and had
+hastened to Lima to intercept them. Ned thought over the situation
+deliberately, and then a daring smile came to his face.
+
+"I wonder if I can?"
+
+He chuckled as he asked himself the question.
+
+"I wonder if I can?"
+
+He paced his room for a moment, and then continued.
+
+"If he goes with me, there will be less suspicion, provided I am
+right in my estimate of the fellow. We may be even left alone with
+the aeroplane! Ah, that would be too good to come true!"
+
+The boy watched the sky to the east from the roof as well as from
+his window, but there were no signs of the aeroplane which Jimmie
+had taken away.
+
+"The little rascal knows what he is doing!" Ned told himself, "but I
+wish he would let me know, too! I reckon I'll take a chance on the
+plan. I'll try anything once, as the Bowery boys say."
+
+Having settled the vexed question in his own mind, Ned went
+whistling down the broad stairway and came out in the lobby. Just
+as he had figured, Collins sat where he could keep an eye on the
+front entrance. When Ned appeared the fellow arose and stepped over
+to him.
+
+"There is nothing new, I'm afraid," Collins said. "I've just been
+over to the police station, and nothing can be done tonight."
+
+Ned thought that Collins must have made pretty good time to get over
+to the police station and back during the short space of time he had
+been out of sight, but he did not say so.
+
+"Anything new about the aeroplane?" asked Ned. "I saw the white one
+come back."
+
+"Perhaps she can give us the information we want about your ship,
+or, perhaps the aviator can," he added with a laugh.
+
+"Why not go and see?" asked Ned, his heart bounding with hope and
+excitement as he noted how eagerly Collins took the bait. "Can we
+get a motor-car here? The machine must be quite a distance away."
+
+"It does look that way," Collins replied, with a yawn, "and we may
+as well take a car, if we can find one. I hope you don't mind my
+going with you."
+
+"Why, I wouldn't go alone!" Ned replied, speaking with perfect
+truth, as Collins discovered later on. "You don't know how glad I
+am to find you up and ready for a little adventure!"
+
+Collins, in turn, told how pleased he was to be of service, and the
+two found a motor-car and started off, taking a road which ran along
+a level strip of land which lay between the sand and the mountains.
+They had proceeded a couple of miles when a motor-car appeared in
+sight just ahead of them, traveling toward the city.
+
+Collins arose in his seat and waved his hand frantically.
+
+"I believe that's Sherman!" he cried. "Sherman's here for a rival
+steam pump firm, but I'll be good to him, especially as there is
+nothing doing in the way of trade. Hey, there, Sherm!" he shouted
+as the two cars drew nearer. "Pull up and give an account of
+yourself!"
+
+Sherman was a dark-faced, black-haired, bewhiskered fellow of
+perhaps forty. He was dressed in a dark business suit and wore
+glasses. The two men talked shop for a moment, and then Collins
+asked:
+
+"Where have you been?"
+
+"Just out for a ride," was the reply.
+
+"You saw the airship come down?"
+
+"Of come, but I'm not interested in airships."
+
+"Then you haven't been out there?"
+
+"Hardly. It doesn't interest me--this aviation craze."
+
+"Then you don't know whether the aviator is out there or not?"
+continued Collins.
+
+"Why, yes, I do know about that," Sherman replied. "I heard this
+driver of mine talking Spanish with a shoofer we met, and learned
+from the mix-up in tongues that the aviator has gone to the city,
+leaving a couple of natives in charge of the machine."
+
+Ned's heart bounded so fiercely that he feared that Collins would
+hear its quick beats! The aviator was not there. Only two
+Peruvians, timid chaps at best! Mr. Thomas Q. Collins might receive
+his reward for his treachery sooner than he imagined, the boy
+thought!
+
+"Well, so long!" Collins cried. "We'll see you in the city
+tonight."
+
+The cars parted, each going its separate way, and Ned and Collins
+were soon within sight of the white aeroplane, which lay in a valley
+a short distance from the road. The spot where it lay was well
+irrigated, and fruits and vegetables were growing all around the
+rope which had been strung about the machine. The aviator had
+evidently paid a good price for the privilege of landing there.
+
+A short distance away from the site of the machine was a small
+house, a tiny affair, with plenty of porches and a flat roof. As
+the two men left the car and advanced toward the machine a man left
+the porch and walked in their direction.
+
+"Probably the farmer," Collins said. "We may have to pay for the
+privilege of looking over the machine."
+
+Much to the amazement of the boy, the man who approached from the
+porch spoke to the two in English.
+
+"What do you want?" he asked.
+
+Ned waited for Collins to make a reply. If Collins really was in
+the conspiracy against Lyman, he would probably show his hand within
+the next few minutes. Just as Ned anticipated Collins gave the
+other a sly signal before he opened his mouth. Ned was not supposed
+to see this evidence of a common understanding, but his watchful
+eyes caught not only that but the answering sign of the other.
+
+"We came up to look over the machine," Collins said.
+
+"Well, you keep away from it," the other replied, fixing his eyes
+keenly on the face of the boy.
+
+"This lad," Collins said, then, motioning toward Ned, "knows
+something about an aeroplane, and wants to inspect this one."
+
+A sly wink followed the remark. It was getting rather cheap to Ned.
+The collusion between the two was so evident that their attempts to
+conceal it appeared very slazy.
+
+"Yes," Ned put in, "I'd like to look the machine over."
+
+"You came in that other aeroplane?" was asked.
+
+Ned nodded, and Collins broke in:
+
+"He's an expert, but he has no machine just at present. A member of
+his party took his machine away this morning," he added, with a
+chuckle.
+
+"So Rowan said," the alleged farmer replied.
+
+"Rowan?" repeated Ned. "Is that the name of the aviator who runs
+this machine?"
+
+"Yes; he is a New York man. Do you know him?"
+
+Ned replied that he had heard of him, knew him to be a splendid
+operator, but had never met him.
+
+After some further talk Ned and Collins were given permission to
+look at the machine, which was called the Vixen. Collins expressed
+his thanks in elaborate language, but Ned went straight to the
+Vixen, which was then guarded by a Peruvian Indian. He was weary of
+the cheap pretense of the other.
+
+"This is a peach of a machine," the alleged farmer explained,
+following Ned as he walked about the great planes. "See here! No
+cranking at all! You just get into the seat, which will carry two
+nicely, and push this button. That releases a spring which whirls
+the propellers until the spark is made, then off you go."
+
+Ned admired the arrangement fully, as he was expected to do. The
+Nelson was fitted out in the same way, but he did not say so.
+Presently the Indian left the circle created by the rope and, going
+into the shelter of the porch, left Collins and Ned with the alleged
+farmer, who announced that his name was Yerkes.
+
+Ned thought this action on the part of the Indian was in obedience
+to a signal from Collins, but could not be too sure of it. Then
+Collins and Yerkes trailed about after Ned as he wandered around the
+airship. The boy saw the former remove certain bits of wood which
+blocked the wheels of the Vixen, also he saw Yerkes, testing the
+gasoline gauge and looking the carburetor over carefully.
+
+"It is all right," the boy thought. "Two hearts with but a single
+thought, two souls that beat as one--or the reverse anyway, they are
+thinking of giving me a ride in this old ice wagon! Pretty soon
+they'll be asking me to get up on the seat and see how easy it is.
+Then one of them will slip this harness about me--the harness
+provided for timid riders--and I'll be off in the air--a prisoner!"
+
+Collins and Yerkes tinkered about the aeroplane for some moments,
+while Ned seemed to be studying the machine. The boy was anxious
+for the decisive moment to come.
+
+Finally Yerkes, went back to the porch and stood there in
+conversation with the Indian for a number of minutes.
+
+When he returned Collins stepped forward toward the seat.
+
+Knowing that the time for action had come, Ned sprang into the
+driver's seat. Collins looked vexed at the movement, but Ned
+laughed down at him.
+
+"I won't hurt your old machine," the boy said. "Get up here, so we
+can see how it rides."
+
+Collins obeyed, first giving Yerkes a significant look which was not
+lost on the watchful boy.
+
+The harness for the visitor's seat was a peculiar one, as Ned had
+noted with considerable satisfaction. There were leather cuffs for
+the wrists and a broad leg band which prevented the guest leaving
+his seat. The cuffs held the hands close together in the lap, the
+idea being to prevent a timid person from grasping the arm of the
+driver in a moment of terror.
+
+"Move on over!" Collins called, as he stepped up, "and I'll see if I
+can take you out of the valley without breaking your neck. Don't
+say a word to Yerkes about his race with the Nelson," he added, in a
+whisper. "He got beaten, and doesn't like to talk about it."
+
+Ned noticed but remained where he was, so Collins reluctantly took
+the other seat. As he did so Yerkes stepped forward, and the Indian
+stationed himself at the back of the machine, where he could give it
+a push down the incline which lay before it, and against which the
+wheels had been blocked.
+
+As soon as Collins was fairly in the seat, Ned gave the harness a
+quick snap, and the click of metal told him that the cuffs had
+closed about Collins' wrists, that the broad strap which held him
+down was in position. Then he pushed the button and the spark
+caught. The Vixen moved down the incline.
+
+Collins tried to lift his hands, but was unable to do so, so he
+lifted his voice instead! Yerkes, in the whirr of the machine,
+doubtless mistook the voice for that of the boy, for he paid no
+attention to it.
+
+"Help! Help!" roared Collins. "Stop the machine! He's got me tied
+down! Stop it, you fool! Stop it!"
+
+Yerkes and the Indian looked stolidly on with grins on their faces,
+and Ned stuck an elbow into Collins' ribs.
+
+"Keep still," he said, "or I'll have to put you out of the speech
+habit. I've got you just where you expected to get me, and you
+ought not to kick about the accommodations."
+
+"Yerkes!" yelled Collins. "Why don't you stop the machine? Catch
+hold of the propellers and yank them off! Put a bullet through this
+young fiend! Anything to stop the crazy thing. I tell you he's got
+me tied in!"
+
+Then Yerkes, recognizing the voice, sprang toward the propellers.
+He made a brisk spring, but was too late. The blades were just
+about an inch out of his reach. Foiled in this attempt, he drew a
+revolver and began firing foolish shots at the machine, none of
+which came near the mark.
+
+In a moment the Vixen was under full speed, the ground dropped away,
+and the last Ned saw of Yerkes and the Indian they were performing a
+dance of rage on the growing vegetables below. Straight to the
+south the machine flew, the motors popping like mad.
+
+The boy saw little crowds in the lighted streets below, looking and
+pointing up at the aeroplane, and then the city streets faded away
+into a dull mat, and there were only the silent peaks, the sea, and
+the deep, dim valleys.
+
+Then Ned turned to his prisoner, who had by this time given over the
+useless struggle against the harness. Collins' eyes were fixed on
+the moonlit Pacific, away off to the west, and the boy's eyes
+followed those of his captive.
+
+A steamer was creeping into the shallow harbor at Calleo, and the
+dark spot on the sand showed that a crowd was there to greet her.
+The Vixen was too far away for Ned to see the surf boats getting
+ready to take off the passengers and freight, but he knew that they
+were there.
+
+It was now eleven o'clock, and the moon was well up in the sky. The
+ribs of the Andes lay like silver in its light. Strain his eyes as
+he might, there was no indication of the Nelson.
+
+"Fine view!" Ned said, presently, giving Collins a nudge in the ribs
+with his elbow. "How do you like it?"
+
+Thomas Q. Collins was near bursting with rage. He hitched about in
+his seat, but to no purpose.
+
+"What does this mean?" he finally found words to say, screaming at
+the top of his voice, for the Vixen was now making good speed.
+
+"I preferred to be the host rather than the guest," the boy said,
+with a shrug of the shoulders.
+
+"I don't know what you mean by that," Collins replied.
+
+"You meant to capture me tonight?" asked Ned.
+
+"Nothing of the kind!" roared Collins.
+
+"You got Leroy and Mike in jail, and you thought you'd burst up this
+relief expedition by putting me out of the way," Ned went on. "Now,
+we'll see who'll be put out of the way."
+
+"What are you here for?" asked Collins.
+
+"You know very well," replied Ned. "But it is too much exertion to
+talk at this speed. Wait until we land and I'll tell you all about
+your intentions! Understand? All about your intentions."
+
+"Much you know about them," shrieked Collins.
+
+Ned made no reply to this, for, away off to the southeast, he caught
+sight of the dipping lights of an airship which might or might not
+be the Nelson.
+
+
+
+
+CHAPTER VII
+
+THE BLACK BEAR IN TROUBLE
+
+
+One still night on the Amazon Jack Bosworth got out a map and turned
+a flashlight on it. Frank and Harry stood looking over his
+shoulder.
+
+"Right here," Jack said, presently, "is where we leave the main
+stream of the Amazon and take to the Madeira."
+
+"How do you know that stream is the Madeira?" asked Frank. "We have
+passed so many large tributaries that I'm all mixed up."
+
+"And why not try some other stream?" Harry questioned. "I've heard
+that the Madeira is full of falls and rapids."
+
+"Anyway," Jack insisted, "it takes us away up into the Andes, almost
+to Lake Titicaca, and that's all any stream will do. As for the
+falls and rapids, do you expect any stream to creep down from that
+great plateau without jumping off occasionally?"
+
+"All right," Frank cut in. "Go your own way to destruction! But
+how do you know that rippling sheet of water off there," swinging an
+arm to the south, "is the Madeira river? It looks like a lake to
+me."
+
+"I found out while you were asleep this morning," Jack replied. "A
+chap came along in a launch and I asked him all about it. He said
+he had just come from the Andes, and advised me to turn back."
+
+"Kind-hearted little fellow, eh?" laughed Harry.
+
+"He wasn't very little," answered Jack. "He was six feet two, and
+was coming out with a finger off and a cut across a cheek bone which
+will last him for a spell, I guess. He cut his finger off because a
+poisoned arrow struck it."
+
+"Cannibals?" asked Harry, with a laugh.
+
+"The same," replied Jack. "Said they chased him for miles."
+
+"We'll curb their appetites with lead," Harry observed.
+
+"If we see them first," added Jack.
+
+So the Black Bear was turned into the Madeira river, which is
+something like seven hundred miles long, and drains the wooded
+country where the black sheep of the land of Brazil live. Away up
+in the hills it is fed by the Beni river, which has its source in
+the mountains east of Lake Titicaca.
+
+ More than once the boys were obliged to haul their motor boat out
+on a rocky "bench," take it to pieces, carry it and most of the
+stock around rapids, and then put it together and load up again.
+Still, they made good time, and on the evening of the third day
+found themselves at the junction with the Beni river.
+
+They were now in a wild and dangerous country. The forests swarmed
+with wild game, the thickets were full of serpents, and the trees
+were often crowded with monkeys. For two days they had seen no
+natives. This was suspicious as it was certain that they had
+penetrated to the home of the cannibal tribes so greatly dreaded by
+hunters and explorers.
+
+It was on the evening of the 21st of August that Jack sent the Black
+Bear into a little creek, shut off the power, and turned to put up
+the panels. It was not very warm, but the atmosphere was sticky and
+heavy with the breath of the woods.
+
+"We'll smother in there tonight," Frank said, observing the actions
+of the other. "Why not leave some of 'em out?"
+
+"If you want a poisoned arrow nestling in your ribs you can sleep
+outside," Jack answered. "For my part, I want to wake up in this
+good old world in the morning."
+
+"I don't think there's any danger yet," Frank said.
+
+But the panels were put up and supper prepared. By this time the
+lads had become accustomed to preparing their own meals, as well as
+providing the fish from the river, and the repast was soon over.
+Then Jack lay back and gazed through the one glass panel of the top
+of the Black Bear.
+
+It was a dark, lowering night. The wind is usually from the east in
+that part of Brazil. Blowing over the Atlantic it gathers up
+moisture to dump on the eastern slope of the Andes. The summits
+drain the clouds and makes Peru a dry country. It was murky now,
+and the clouds hung low.
+
+"What do you see up there, Jack?" asked Frank. "Trying to study
+astronomy, with not a star in sight?"
+
+"There you are wrong," Jack replied. "There is at least one star in
+sight."
+
+"With that mass of clouds drifting over the sky?" laughed Harry. "I
+reckon you must be seeing things not present to the senses!"
+
+"Come and look, then," Jack invited. "Look straight up, and you'll
+see a star."
+
+Frank placed himself under the glass panel and looked up.
+
+"Well?" Jack demanded, in a tone of triumph.
+
+"It's something," Frank exclaimed, "but I don't believe it is a
+star."
+
+"It may be a reflector at the top of the Flatiron building," grinned
+Jack. "What is it, if it isn't a star?"
+
+"Look yourself!" cried Frank.
+
+The boys were all looking now. They saw the light which Jack had
+mistaken for a star flashing to and fro under the clouds like a
+firefly. It rushed earthward with amazing speed for an instant,
+then spiraled upward again. Once it came directly over the Black
+Bear, and seemed about to drop down.
+
+Jack threw a couple of panels open, and then the whirr of motors
+reached their ears. Frank sprang outside and turned a flashlight
+upward.
+
+"There's your star!" he shouted to Jack.
+
+"Quick!" Harry cried. "Wigwag with that light. It is the Nelson!
+They may be able to see us!"
+
+"Yell, every soul of you!" directed Frank. "Yell! She is going
+away!"
+
+The boys waved their lights frantically and shouted at the top of
+their voices, but the light in the sky crept away to the west and
+soon disappeared, evidently passing above the clouds which lay like
+a black blanket over the Brazilian forests.
+
+"Great heavens!" Jack sighed. "If we could only have made them
+hear! I'll bet they've been to Paraguay and released Lyman. Now
+they're going back home! Fine show we now stand of having any fun
+with them!"
+
+"They went west," Harry corrected. "That isn't the way home!"
+
+"I'd like to know just what success they have had," Jack went on.
+"Say," he continued, "can't we do something to attract their
+attention? Why not set fire to some big dry tree and let her blaze
+up?"
+
+"I just can't have it this way!" Harry said. "I can't stand it to
+have them come so close to us and then go away without knowing we
+are here. We've got to bring them down in some way."
+
+"But they've gone!" Frank declared, gravely.
+
+"If we make a big blaze," Jack hastened to say, "the reflection on
+the clouds will attract their attention, and they'll come back.
+They won't be able to see the fire itself, of course, but they'll
+see the reflection, and that will bring them down to investigate.
+Then we'll fire our revolvers and wigwag with blazing sticks until
+they see who we are."
+
+"It may not be the Nelson," Harry suggested.
+
+"I don't believe there's any other aeroplane sailing about the roof
+of the world," Frank replied. "Of course it is the Nelson!"
+
+"Perhaps the Nelson was followed," Harry went on. "I've heard of
+such things. The chap in that machine may be looking for Ned.
+Anyway," he added, "it won't do any harm to let the aviator, whoever
+he is, know that we are here. Come on, let's go ashore and build a
+big fire."
+
+"I certainly would give a year's growth to know whether that is the
+Nelson," Harry said, as the boys sought the shore and began
+gathering dry wood, which, it may be well to add, was not easy to
+find, as there had been quite a shower during the day. "For all we
+know," he continued, "there may be another aeroplane here. If the
+people who are trying for the Lyman concession are as active here as
+they seem to have been in Paraguay, they may have half a dozen
+airships out after the Nelson."
+
+Finally a quantity of wood which was fairly dry was secured, and
+Jack bundled it up against a dead tree which seemed to run straight
+up into the sky until it touched the clouds. But when the boys came
+to apply matches they discovered that the wood was not dry enough to
+be ignited in that way.
+
+"I'll get a gallon of gasoline and pour over it," Frank explained.
+"Then we can run like blazes when we touch her off. What?"
+
+The gasoline was brought, and the blaze started with a mighty
+concussion of the air. A portion of the highly inflammable fluid
+had entered a great crevice in the dead tree, with the result that
+there was an explosion which resounded through the forests for
+miles. Then the flames mounted the tree, which was soon blazing
+like a great torch.
+
+"I guess that will attract their attention!" Jack said, shielding
+his face from the intense heat.
+
+"Yes," Frank replied, "and I'm afraid it will attract the attention
+of others, too. You know we were told to sneak through this country
+like little mice!"
+
+"It is too late now!" Jack said, a shadow of anxiety coming over his
+face. "We are in for it, I guess. What shall we do?"
+
+Above the crackling of the flames, above the drawing and sighing of
+the wind, there now came a strange sound which seemed to proceed
+from the fire-tinted clouds above. Now and then branches of the
+nearby trees stirred mysteriously, and at times a wild shriek rose
+above the monotonous chattering.
+
+"Monkeys!" cried Jack. "They've come out to help us bring the
+airship to earth. Good little beasts!"
+
+"Don't be in too much of a hurry to give the little devils a
+certificate of good character!" Harry answered. "They may make
+trouble for us."
+
+After a time the foolish, wrinkled faces of the monkeys were seen
+peering from trees. Then, above the din they made, above the
+crackling of the fire, constantly mounting higher, came a scream
+almost like that of a child.
+
+"That's a jaguar!" Harry declared, "a South American tiger, and we'd
+better be getting toward the boat."
+
+"The animals won't come near the fire," Frank said. "We may as well
+remain here and see the menagerie."
+
+Directly it seemed to the excited lads that all the wild animals in
+South America were assembled about their signal. Harry declared
+that he heard the call of the red wolf, the scream of the tiger cat,
+the wail of the puma, the vicious snarling of the wild dog.
+
+While the boys listened to the chorus their efforts to attract the
+attention of the aeroplane had produced, there came into the discord
+another sound--the hissing of a monster serpent. Heretofore the
+boys had little to do with Brazilian forms of animal life, for they
+had kept near the middle of the main stream of the Amazon, and also
+about in the center of the Madeira and the much smaller Beni, which
+was only a creek when compared with the other rivers.
+
+Occasionally they had seen a monster cayman nosing against the
+current, and at times their progress had been retarded by turtles,
+but they had never before seen anything like this. Their fire had
+certainly brought out a combination in nature which would have been
+decidedly interesting if it hadn't been so threatening.
+
+"Me for the boat!" Jack said, with a shiver, as the serpent launched
+his head and a third of his body from the tree and swept about in
+widening circles. "I never could endure snakes!"
+
+"I'm going to take a shot at it," Frank said. "I'd like to see him
+take a tumble into the fire."
+
+"Better let him alone," Harry advised.
+
+Frank was about to fire when Jack caught his arm and held up his
+hand in a listening attitude.
+
+"What is it?" Frank asked.
+
+"Human voices!" was the quick reply.
+
+"Inhuman voices, I should say," Harry observed, after a second of
+silence.
+
+A chant unlike anything the boys had ever heard before undulated
+through the forest. It rose and fell with the gusts of wind, and
+always nearer to the fire.
+
+"This is a new one on me!" Jack cried. "It is also another reason
+for getting to the boat! Come on, fellows!"
+
+"I'm not going to run until I find out what that is," insisted
+Frank. "I'm going to write a newspaper story about this menagerie!"
+
+"If you want your story published in this world," Jack cried, "you'd
+better get under cover, for that's the chant of the head hunters!"
+
+"Wow!" cried Frank, and he beat both his chums to the boat.
+
+ "I guess we've started something!" Jack said, as he busied himself
+putting up the few panels which had been removed when they went
+ashore. "Now, some one push that button, and I'll get the Black
+Bear out of this creek. A good old scout like the Black Bear has no
+business associating with the wild animals on shore."
+
+"Right you are!" shouted Harry, and the propellers began moving.
+Still, the boat made no progress to the rear, the reverse being on.
+
+"What's doing?" demanded Jack. "You'd better hurry, for the head
+hunters are coming right along. See that big chief over there?
+He's got a club that would level the Singer building at a blow!"
+
+"I can't make her back," Harry complained. "There's something the
+matter below her in the stream. It was all clear when we came in."
+
+In an instant all was intense excitement on board the motor boat.
+There was only one way in which the savages could reach them, and
+that was to block their passage out and starve them to death! Had
+this system been resorted to? Had the cunning savages obstructed
+the little stream while the lads were busy building their fire and
+observing their menagerie, as they called it?
+
+These questions were in the minds of all as efforts to back the
+Black Bear were redoubled. Finally Jack opened a panel at the rear
+and looked out, a thing he should have done at first.
+
+What he saw was a large log blocking the channel. The propellers
+were pounding against it, and one of them was broken.
+
+"I guess the little brown men have got us good and plenty," he said,
+slowly, as he reached forward and shut off the power. "While we
+were playing about the blaze they plugged the river."
+
+"They can't get in here, anyway!" Frank consoled.
+
+"No; they'll wait for us to get good and hungry and go out!" Jack
+replied.
+
+The situation was a serious one. The head hunters now appeared in
+the open space about the blazing tree and shook their spears and
+their clubs at the boat. Now and then an arrow with a poisoned tip
+struck the side of the Black Bear.
+
+"They'll never leave until they get us!" Jack said, presently, "and
+so we may as well get a few of them. Get your guns, boys."
+
+"Just you wait, old hard luck prophet," Frank exclaimed. "Look up
+through the glass panel above your head and tell me what you see."
+
+"Well," Jack replied, "it looks like we had established
+communication with the Nelson at last. And also with the Greatest
+Show on Earth!" he added, as a mighty roar went up from the shore.
+
+The other boys crowded the panel and looked out. The clouds above
+were red with the reflection of the blazing tree, yet against the
+mass a different light blazed out. This light moved about, from
+north to south and back again, as if searching out the reason for
+the strange happenings below.
+
+The popping of her motors could be plainly heard, and so it was
+probable that those on the airship could hear the wild animal
+concert which was going on in the woods. Harry pushed a panel aside
+and fired three quick shots. The aeroplane wavered above the river
+a moment and then drifted away.
+
+"They must know there's somebody down here in trouble!" said Harry.
+"Why don't they throw down dynamite? That would give the savages
+all the heads they wanted for a time, I guess."
+
+The boys fired again and again, flashed their lights in wigwag
+signals, but the aeroplane did not come nearer. Instead it whirled
+swiftly about in a circle for a moment and then shot out of sight
+beyond the clouds.
+
+And every moment the circle of savage faces gathered closer about
+the Black Bear, effectively blocked in the narrow stream.
+
+
+
+
+CHAPTER VIII
+
+THE VIXEN TAKES A TUMBLE
+
+
+While Ned, from the driver's seat on the aeroplane he had so
+cleverly taken from the enemy, watched the distant light flashing
+over the mountains, the bulk of an airship came into view. While
+the boy was cheering himself with the hope that he would soon be in
+touch with Jimmie, however, the light disappeared, and the dark body
+of the machine was no longer visible.
+
+"There's been an accident!" Collins muttered maliciously, in Ned's
+ear. "That little chap can't run an aeroplane!"
+
+"What is there over in that direction?" Ned asked, without replying
+to the other's suggestion of evil. "Can one land there?"
+
+"Not in the night," was the sullen reply. "Unless you want to
+commit suicide and murder me in the bargain, you'd better keep in
+the air."
+
+"What's over there?" repeated Ned.
+
+"Mountains," was the surly reply.
+
+Ned pointed to a dark stretch below.
+
+"That must be a valley," he said. "Anyway," he went on, "I'm going
+down, and if we come to a point where it is jump or go down with the
+machine, I'll cut you loose, so you'll have the same chance for your
+worthless life that I do. That's more than you would do for me
+under the circumstances!"
+
+Ned guided the Vixen to, as near as he could make out, the location
+of the other airship at the time of her disappearance and dropped
+down. As he swept toward the earth the peaks of the Andes rose
+above him.
+
+Down, down, down he dropped, looking out keenly for trees and jagged
+rocks. At last he saw a level stretch of land just below. The
+rains had carried sand and ruble down from the mountains and filled
+a valley perhaps three hundred feet in diameter with the wash of the
+slopes. This formed what seemed to be a pretty good landing spot,
+and Ned managed to bring the rubber-tired wheels of the airship down
+without mishap.
+
+Then, rolling swiftly under the impetus given by the now shut-off
+motors, the wheels carried the bulk of the ship along for some
+distance and dropped. Ned felt himself falling.
+
+Thomas Q. Collins cried out in fright, and tried to kick himself
+free from the harness, but the leather straps held. When the drop
+ended there was, a jar and a crash, and the planes lay in a confused
+heap in the bottom of a depression well stocked as to floor and
+sides with jagged rocks.
+
+In descending, the dragging propellers had loosened some of the
+rocks, and they, rolling down the declivities after the machine, had
+fallen upon and crushed the planes. Several great boulders thunked
+near Ned's head, and Collins set up a great howl as a small stone
+landed on the back of his neck.
+
+Although the stars were shining brightly and the moon was abroad, it
+was quite dark down in the hole into which the Vixen had fallen.
+Ned could see slanting walls on all sides, and glimpse, above, the
+slope of the deceiving level which had first caught the wheels, but
+that was about all.
+
+Finding himself uninjured, his first move was to get out his
+searchlight and make an inspection of Thomas Q. Collins, who was
+roaring like a wounded bull.
+
+"Are you hurt?" the boy asked.
+
+"Hurt!" howled the captive. "My head is broken, and my arms are
+smashed! What do you mean by tying me up and then wrecking the
+machine?"
+
+Ned searched the fellow's clothing, removed a revolver and a dagger,
+and then snapped off the harness which still held him to the seat.
+Collins stretched himself and lunged at the boy.
+
+"Keep away!" warned Ned.
+
+"I'll show you that no Bowery kid can double-cross me!" Collins
+screamed, paying no attention to the automatic in Ned's hand. "I'll
+show you!"
+
+The next moment Ned would have fired, with the intention of wounding
+the enraged fellow, but a boulder intervened, and Collins went down,
+striking his head on a rock. When the boy bent over he found him to
+be unconscious.
+
+Bringing the leather straps of the harness into use again, Ned bound
+the man's hands behind his back, so as to prevent a second attack,
+and set out to look for water. He had not long to look, for a tiny
+spring bubbled out of the bottom of the pit and found its way toward
+the valley below through a crevice in the rock. In a short time
+Collins, under the influence of a right cold bath, sat up and
+addressed the boy in language which would not have been considered
+suitable in the presence of a lady.
+
+"You've done it now!" the alleged steam pump salesman cried.
+"You've dumped us into a pit in the heart of the Andes, and we'll
+starve before any one comes to our assistance. Take this strap off
+my wrists, or I'll have your life!"
+
+"You're an excitable party," Ned laughed. "You want your own way!
+I've been wondering, while I've been giving you first aid to the
+indignant, what your name really is, and where you live."
+
+"You'd better be trying to ascertain where we are," declared
+Collins, "and what chance we have of getting out alive."
+
+"I think I can tell you about where we are," Ned replied. "We were
+in the air not far from five hours. The Vixen will run about sixty
+miles an hour, therefore we are not fax from three hundred miles
+from Lima, in a southeast direction. Do you know if we are near any
+town?"
+
+Collins sulked a short time and then nodded toward a great peak
+which rose above all the others in the distance.
+
+"That may be Vilcanota," he said.
+
+"Old Vilcanota seems to be a whale," Ned observed, looking up at the
+snow cap.
+
+"Over 17,000 feet high," was the sullen rejoinder.
+
+"Well," the boy went on, "if that really is Vilcanota, we are still
+in the land of the living. In fact, we can't be more than
+twenty-five miles from a town, and there is a railroad--so my maps
+say--over to the east. It ends at Sicuani, and there the upper
+branch of the Uacayli river begins. This river empties into the
+Amazon at the head of steamboat navigation, the maps say."
+
+"You seem to know a lot about this part of South America," gritted
+Collins.
+
+"And over to the south," Ned went on, "is Lake Titicaca, and over
+the mountains from that body of water is Coroico, where the Beni
+river starts on its long run to the Amazon, by way of the Madeira
+river."
+
+"Well," snapped Collins, drawing hard at the strap which held his
+wrists, "you can't sit here and figure yourself out of this hole.
+Why don't you do something?"
+
+"Why, I thought it might be a good plan to wait until dawn," laughed
+Ned. "Then I may be able to repair this machine."
+
+"Repair nothing!" stormed Collins. "And in the meantime, I presume
+you think you are going to keep me tied up like a calf going to
+market?"
+
+"About that way," Ned responded, whereat the captive snorted out his
+rage and rolled over on his face and pretended to be asleep.
+
+In a short time dawn shone on the tops of the tallest mountains, and
+directly it crept slowly down into the pit where the wrecked
+aeroplane lay. By this time Ned had mapped out a course of action.
+
+The aeroplane he had seen in the night had descended not far from
+this spot, and he had decided to climb to some convenient height and
+look about for it. If he could come upon the Nelson, in good
+sailing condition, there would be no need of repairing the Vixen, or
+trying to do so.
+
+Collins had counterfeited sleep until, utterly exhausted, he had
+actually dropped off into slumber, so Ned had no captive to watch
+for the time being. Before leaving for a tour of inspection he
+examined the broken planes and discovered that it would be
+impossible for him to repair them, at least without the necessary
+tools and materials.
+
+Climbing to the level bit of sand, then, he faced the east and began
+the ascent of a mountain spur which seemed to reach the very
+heavens. It was a beautiful morning, the air being sharp and clear
+at that height. Ned felt that he could have enjoyed the beauties of
+nature more fully, however, if he had something in the way of
+breakfast!
+
+He climbed steadily for an hour, and then came to a narrow ledge
+which seemed to surround one of the lower peaks of the mountain.
+Passing around to the south, he heard a shout, then a fall--a
+bumping fall which told of a body bouncing from one rocky level to
+another.
+
+He ran around the angle ahead of him and came out on a shelf-like
+elevation from which a green little valley, half way up the side of
+the mountain, might be seen. In the center of the valley, carefully
+blocked against sudden motion, lay the Nelson.
+
+Ned could have danced with delight. The aeroplane appeared to be in
+perfect condition, but there was no one insight. Jimmie and Pedro
+must be about somewhere, the boy thought, as he considered the most
+practical way of reaching the valley, but where were they?
+
+He was about to call out in the hope of arousing one of the aviators
+to action when he saw a hand waving at him from underneath the gray
+planes. A more careful inspection of the spot revealed the dirty
+face of little Jimmie, who was lying on his face, an automatic in
+each hand. Pedro was nowhere to be seen.
+
+Ned watched the signaling hand for an instant and then, in response
+to what it said to him, scudded around the angle of rock by which he
+had reached the shelf. As he did so an arrow whizzed past his right
+ear and blunted against the rocky wall.
+
+The situation was not difficult to understand. Jimmie had dropped
+the Nelson into the little valley and had there been attacked,
+either by savages or those interested in the defeat of the Boy Scout
+expedition to Paraguay, though how the latter could have reached
+that lonely spot so soon after the landing of the aeroplane was a
+mystery which the boy could not fathom.
+
+Following the attack, Jimmie had hidden under the planes, and Pedro
+had probably taken to his heels. The situation explained,
+doubtless, why the boy had not returned with the airship. He had
+been held there by the enemies, virtually a prisoner.
+
+After a short pause, during which Ned listened intently for some
+sound of pursuit, the boy moved cautiously to the shoulder of rock
+and looked around it to the shelf. There was no one in sight, so
+he pressed on, and once more came within view of the aeroplane.
+
+Back of the planes he saw a head lifted from the lip of a gully
+which cut the valley like a trench. It was not the head of a
+savage, nor yet the head of a Peruvian mountaineer, for it was
+covered down to the eyebrows by a flat-topped leather automobile cap
+which was adorned with driving goggles! Evidently an American!
+
+While Ned, himself unseen, watched the cap and the goggles, the
+wearer lifted himself and looked up over the edge of the gully. He
+wore a gray suit, tailor-made, from all appearances.
+
+Back of him three ill-visaged Peruvian Indians also raised
+themselves to get a view of what was doing in front.
+
+So the savages were led by an American! Instead of the automatic of
+civilized warfare, the enemy was resorting to the poisoned arrow of
+the barbarian!
+
+An American there and in automobile costume! Where was the machine,
+and how in the name of all that was wonderful had it been brought to
+that rough country?
+
+And why were the enemies crouching there, when their only opponent
+was a boy, hidden if his position may be so termed--under the planes
+of an airship--planes which would offer little resistance to an
+arrow or a bullet?
+
+But while the boy looked and wondered a shot came from the very
+shelf on which he stood, and one of the exposed Indians dropped in
+his tracks. Then the situation became a bit clearer.
+
+Pedro had escaped from the valley to the shelf of rock, and was
+standing guard there shooting whenever the attacking party attempted
+to reach the aeroplane.
+
+In a moment the automobile cap and goggle and the evil faces of the
+Indians disappeared from view. The attacking party had dropped back
+into the gully, which was some distance from the machine.
+
+Waiting a moment, in order to make sure that no one was stirring
+behind the shoulder of rock, Ned called softly:
+
+"Pedro!"
+
+"Hello!" came the answer back.
+
+"'Where are you?" asked Ned, recognizing the voice of the Peruvian
+he had talked with at Lima.
+
+"In a notch of the rock," came the answer, in Spanish.
+
+Ned moved along the shelf, and soon came to where Pedro stood,
+sheltered by a jutting ledge. The journey was not accomplished
+without attracting the attention of the others, for an arrow whizzed
+past his head as he crept into the angle with Pedro.
+
+Pedro expressed great joy at the arrival of the boy, and explained
+that the situation as then shown had existed since dawn. On the
+afternoon of the previous day Jimmie, being then about to return to
+Lima, had found it necessary to land in order to repair a slight
+break in a plane.
+
+The driver of the pursuing Vixen, noting the temporary disablement,
+had circled around the valley for a short time and then returned to
+Lima. It was Pedro's idea that the Vixen would not return with
+assistance, but with enemies who would destroy the machine, leaving
+Jimmie and himself to find their way out of the mountains as best
+they could.
+
+Jimmie, Pedro said, had been unable to fix the Nelson for flight
+until about daylight, and then the attacking party had appeared.
+Since then it had been impossible to get the machine into the air,
+as every motion at the airship brought a bullet or a poisoned arrow.
+
+Just before Ned's arrival, an Indian had, by making a long journey
+around the cliff, gained the shelf of rock where Pedro was
+stationed, and been caught unawares and thrown down into the valley.
+It was the cry and the fall of this foe that Ned had heard.
+
+"But," Ned said, "the Vixen must have summoned some one active in
+the conspiracy before returning to Lima, for the man over there came
+in an automobile, and did not come very far either. He certainly
+did not come from Lima, which is more than three hundred miles
+away."
+
+"He might have come from Sicuani," replied Pedro. "That is over to
+the east, and not more than twenty miles off. I have heard that
+there is a path by means of which a motor car can reach this place.
+Yes, he must have gone to Sicuani, otherwise this man of the motor
+car would not be here," Pedro added.
+
+This cleared the situation not a little, and Ned was now encouraged
+to make an attempt to reach the Nelson, which Pedro declared to be
+in good condition for flight. If the others had come in an
+automobile, there could not be many of them. Probably not more than
+six in all, and two had been wounded, or killed.
+
+Pedro insisted that, with Ned guarding him from the shelf, he could
+reach the machine, but the boy thought it wiser to make the
+desperate journey himself. Even if the Indian reached the Nelson,
+the two of them might not be able to get the machine into the air,
+as Jimmie had had little experience in running a plane.
+
+So, after explaining to Pedro that he would be taken up later, Ned
+began the task of making his way down the almost perpendicular face
+of the cliff. Much to his surprise, there were no hostile
+demonstrations from the gully in which the attackers had disappeared
+a short time before.
+
+Instead of shots and the whiz of arrows, the boy heard, when half
+way down the slope, the distant whirr of a motor car!
+
+"There is some trick in the wind," Ned thought. "They would never
+run away in that manner because of the wounding of two Indians and
+the arrival of one boy from the outside."
+
+It was deathly still in the valley where the aeroplane lay. Sounds
+from a distance came with remarkable distinctness, so the popping of
+the motors of the automobile were plainly heard, and the direction
+taken by the machine was thus made known.
+
+Jimmie sprang up, uninjured, as Ned advanced and the two grasped
+hands with more than ordinary feeling. Almost the first thing
+Jimmie said was:
+
+"I saw the lights of the Vixen last night, but thought the other
+fellows would be in charge of her. How did you manage to geezle
+her?"
+
+"We stole her--and smashed her." Ned laughed, telling the remainder
+of the story in as few words as possible.
+
+Presently Pedro came down from the cliff and went over to the place
+where the man he had thrown down the declivity had fallen. He found
+him quite dead. With a solemn shake of the head he laid the body in
+a sheltered nook and joined the others.
+
+It took only a brief examination of the machine to show that she was
+in as good condition as ever, and Ned prepared to mount and leave
+the valley. Then the popping of additional motors broke out on the
+still air, and Jimmie grinned.
+
+"I guess you didn't smash the Vixen much," he said. "Anyway that
+man in the motor car seems to have repaired her broken wings.
+Probably had the tools to do it with him. They've got some dirty
+scheme on!"
+
+"Yes," Ned replied, grimly, "or they wouldn't have left the gully.
+Collins will be on deck again in about a minute!"
+
+
+
+
+CHAPTER IX
+
+A TRAGEDY IN THE AIR
+
+
+"Then we'd better be gettin' up in the air, so we can see what's
+going on," Jimmie replied. "I'd like to see where the motor car
+goes."
+
+"We can satisfy our curiosity on that point without going up in the
+air," Ned answered. "The Vixen was left just over that cliff.
+There is a valley--a dent in the slope of the mountain--on each side
+of that elevation, and the Vixen and the motor car are in one of
+them and the Nelson in the other."
+
+Jimmie started away on a run almost before Ned had finished
+speaking. In a few moments he was seen on the shelf, then he darted
+around the shoulder of rock and was lost to view. The popping of
+the motors continued.
+
+Ned hesitated a moment, uncertain as to the advisability of leaving
+the machine in the sole care of the Indian, and then followed. When
+he gained the shelf on the opposite side he saw the Vixen slowly
+lifting in the air. The automobile stood above her, on the level
+yet treacherous spot where Ned had landed. In it were Thomas Q.
+Collins and the man he had seen in the automobile cap and goggles!
+
+The Vixen did not look to be in good repair, just as Ned had
+supposed, for the newcomer had had only a short time to work over
+her, but for all that she was slowly leaving the narrow pit into
+which she had tumbled. Her motors were working, but did not appear
+to be doing any lifting.
+
+Then Ned saw that a rope attached to the machine was doing the work.
+The motor car, moving very slowly forward, was pulling her up the
+steep acclivity, her rubber-tired wheels drawing and bounding
+against the rocks.
+
+"If they get her up on that level space," Jimmie predicted, "they'll
+get her up in the air. You can see where they've been patching the
+planes, and the motors are workin' all right."
+
+"What I'm interested in, just now," Ned said, "is that automobile.
+I'd like to find the highway through which she entered that valley.
+It must be through some tunnel, for there's no path over the
+slopes."
+
+"Then we'll keep out of sight an' watch," Jimmie observed. "See
+there!" he cried, as the wheels of the Vixen struck the level area.
+"She'll be in the air directly. One of the niggers is gettin' in!"
+
+"What's that he's loading on?" asked Ned.
+
+"Stones, as I'm a living boy!" he went on, excitedly. "Jump for the
+Nelson, kid, and get her into the air! You see what they are going
+to do?"
+
+It was quite evident what the intentions of the others were. The
+Indians were loading the Vixen down with sharp-pointed stones and
+long wisps of dry grass; out from the nooks of the valley by
+Collins, who had now left the automobile.
+
+"We've just got to get the Nelson up in the air!" Jimmie cried.
+"They're gettin' ready to drop stones an' blazin' grass down on her
+planes. We've just got to get there before the Vixen sails over
+her!"
+
+Stopping no longer to observe the motor car, or watch her course out
+of the valley, both boys dashed around the shoulder of rock and
+began working their way down into the place where the Nelson lay,
+with Pedro, all unconscious of the approaching danger, sitting in
+the driver's seat and wondering if he was ever going to eat again!
+
+The whirr of the motors in the air soon told the sweating lads that
+the Vixen was rising from the ground. Just how they had managed to
+repair her so quickly was a wonder to Ned, but he had no time to
+consider that side of the case then.
+
+"Do you see her yet?" panted Jimmie, as the two paused a moment on
+their toilsome way downwards.
+
+"Not yet," was the reply, and Ned almost dropped a dozen feet and
+caught on the point of a rock which jutted out from the wall.
+
+"Gee!" cried Jimmie. "That was a tumble! Got a good hold, there?
+Then catch me!"
+
+Before Ned could remonstrate the reckless little fellow had dropped.
+The impact of his body forced Ned from the crevice in which he
+clung, and together they rolled down a score of feet, bringing up in
+an angle from which a fall would have been fatal.
+
+Ned came out of the tumble unharmed, but Jimmie lay like a rag in
+his arms as he straightened out and looked upward. The Vixen was
+rising over the cliff!
+
+Ned drew his automatic and fired three quick shots in the air, but
+the aeroplane sailed on, apparently unharmed. In a moment she was
+directly above the Nelson, and Pedro was fleeing for his life.
+
+Standing there helpless, with the unconscious boy in his arms, Ned
+saw the driver of the Vixen rain great stones down on the frail
+planes of the Nelson. Then a puff of smoke came from the driver's
+seat, and Ned saw that the wisps of straw were being ignited to
+finish the work begun by the rocks.
+
+He fired volley after volley at the man who was doing the mischief,
+but he was so unnerved and excited that his bullets went wild. The
+crash of stones on the breaking planes sounded louder to him than
+did the explosions of his own revolver.
+
+In a moment a blazing wisp of dry grass, or straw, dropped from the
+Vixen and sifted through the still air, the individual pieces of the
+bundle falling apart. Some of the little swirls of flame died out
+as the material passed downward, but others held, and dropped on the
+wounded planes!
+
+Ned shouted to Pedro, ordering him to smother else incipient blaze
+with his coat, or anything the he could find, but the Peruvian was
+nowhere to be seen. Terrified at the movements of the aeroplane, he
+had hidden in the rocks.
+
+Again and again the man on the Vixen lighted wisps of dry grass and
+hurled them down. Directly the planes were in a blaze. Ned laid
+Jimmie down on a narrow ledge and finished emptying his revolver,
+but to no purpose. He had never done such bad shooting in his life.
+
+But Fate was abroad in the Andes that morning!
+
+Presently the driver of the Vixen dropped his last wisp and shot
+upward, apparently not caring to engage in combat with the boy who
+had used him for a target so unsuccessfully.
+
+As the aeroplane passed across the top of the valley, Ned saw a
+little tongue of flame on the under plane. The driver evidently did
+not understand his peril, for he mounted higher and drove straight
+to the north.
+
+Ned watched the finger of flame grow as it bit into the fine fabric
+of the plane with something like awe in his heart. If the driver
+did not see his danger instantly and hasten down, nothing could save
+him.
+
+While the boy watched, almost breathlessly, Jimmie stirred and
+opened his eyes. He had a bad cut on his forehead, but otherwise
+seemed to have suffered little from his terrible fall.
+
+"Gee!" he cried, looking up at Ned with a grin. "I guess I took a
+drop too much!"
+
+Ned did not answer. He was too busy watching the tragedy which was
+taking place in the air. Jimmie followed the direction of his eyes
+and caught his breath with a gasp of horror.
+
+"He'll burn up!" he cried.
+
+Both planes were now on fire, and the driver knew of his peril. It
+seemed to Ned that the fellow's clothes were on fire, too, for he
+writhed and twisted about as he turned the aeroplane downward.
+
+"He'll get his'n!" Jimmie declared.
+
+The Vixen came down almost like a shot, leaving a trail of flame and
+smoke behind her. Then the end came.
+
+The charred planes gave way and the frame dropped, carrying the
+driver with it. They whirled over and over in the air as they came
+down. The fall must have been fully five hundred feet, and Ned knew
+that it would be useless for him to seek the man who had worked so
+much mischief to the Nelson with a view of doing him any service.
+
+Below, the Nelson was sending up sheets of flame. Pedro now ran out
+of his hiding place and attempted to check the fire, but his efforts
+availed nothing.
+
+"It is gone, all right!" Jimmie said, with a sigh. "Now, how are we
+goin' to get out of here? That's what I'd like to know."
+
+"We'll have to get out the same way the others do," Ned replied.
+"They have lost their aeroplane too."
+
+"Yes," agreed the little fellow, "but they have a motor car, and
+we've only our shanks' horses!"
+
+Ned extinguished the burning woodwork on the Nelson and made a hasty
+estimate of the damage done.
+
+"The motors are not injured," he reported. "If we can get something
+that will do for planes, we can get her out."
+
+"Then," said Jimmie, "I reckon it's me for the highway! I'll chase
+that automobile into where it came from. I'll bet I'll find cloth
+of some kind there."
+
+"It might be better to send Pedro," said Ned.
+
+"All right!" the little fellow agreed. "Then you and I can sleuth
+about this rotten country in search of gold! They say there's gold
+in these hills!"
+
+The purr of the motor car's engines now came again, and Pedro
+hastened up the ledge and followed down into the valley where she
+lay. In a moment she was out of sight, and the Peruvian was moving
+toward a rift in the wall of rock to the east.
+
+But Ned, watching from above, saw that there was only one person in
+the car. Mr. Thomas Q. Collins had been left behind!
+
+"That's strange!" Ned mused. "Why should he remain here? What
+further mischief has the fellow in mind?"
+
+When Ned returned to the machine he found Jimmie busy polishing the
+scorched steel work.
+
+"All she needs is new planes!" the lad cried.
+
+"Jimmie," Ned asked, "when you came here yesterday, did the Vixen
+follow you closely, or did she stand off and on, as seamen say, and
+take note of your course indifferently? What I want to know is
+this: Did the driver seem anyway excited when you speeded over this
+way?
+
+"He followed tight to my heels," replied the little fellow. "Then,
+when he saw me land, he whirled about and went away."
+
+An idea which seemed almost too good to be true was slowly forming
+in Ned's brain. Why had the Vixen always followed the Nelson? Why
+had she spied upon her without in any way interfering?
+
+Again, why had Thomas Q. Collins been left there in the wilderness?
+Surely there were no accommodations in sight in those valleys--nothing
+to subsist on, no shelter from the weather.
+
+He might, it is true, have remained out of a spirit of revenge,
+hoping to punish Ned for his treatment of him, but this explanation
+did not appeal to the boy. With the Nelson hopelessly out of
+repair, he could well afford to leave the lads to their fate, as the
+chances that they would be able to get out alive--being strangers to
+that country and, supposedly, to mountain work--were about one to
+ten.
+
+And so, Ned reasoned, there must be some other incentive for the
+action taken by Collins. He had a subconscious impression that he
+knew what that incentive was, but hardly dared to whisper it to
+himself.
+
+The boy's reverie was interrupted by Jimmie, who had been running
+back and forth in the valley in quest of wild berries, or something
+which would serve as food.
+
+"I could eat a whale!" the little fellow shouted.
+
+"Catch a hare and cook him," Ned suggested.
+
+"The hares here are not exactly like our rabbits, but they are good
+to eat. If you go over into the little jungle below, at the end of
+this bowl, you might find one."
+
+Ned, still wondering if what he hoped might be true, turned to the
+cliff which separated the two valleys and began a careful inspection
+of the rock formation. Away around to the east, under the shelf
+which ran like a terrace around the elevation, he came upon what he
+was looking for.
+
+The shelf extended outward from the face of the rock, and under it,
+setting back into the cliff perhaps a dozen feet, was a cavern which
+looked out on the valley where the Nelson lay, but from which the
+machine itself was not in sight.
+
+The floor of the cavern showed traces of human habitation. It had
+undoubtedly been occupied as a shelter from storms by mountaineers
+for centuries.
+
+But the evidences of occupation which Ned saw were not those showing
+distant use. There was a tiny fire burning in a crevice which
+served as a chimney, carrying the smoke far up into the sky before
+discharging it.
+
+Scattered about the fire were tin cans, some empty, some containing
+food of various kinds. Thrown over a heap of broken boxes in a
+corner was a coat--a tailor-made coat of fine material.
+
+On a little ledge at the rear were a safety razor, a small mirror,
+and a shaving mug. Ned picked up the coat and thrust a hand into an
+inside pocket. That, he thought, would be an easy way to ascertain
+the identity of the owner.
+
+In a moment he drew forth a folded paper, covered with figures in
+pencil. The figures were in columns, as if the maker had been
+setting down items of expense and adding them up. The total was in
+the millions. The calculations of a cattleman, covering shipments
+and receipts!
+
+Ned continued his search of the coat and presently came upon a
+packet of letters, all enclosed in envelopes and neatly ticketed on
+the back. They were enclosed in a rubber band, and showed careful
+handling.
+
+And the envelopes, every one of them, were addressed to Dr. Horace
+M. Lyman, Asuncion, Paraguay!
+
+
+
+
+CHAPTER X
+
+DINNER IS SERVED
+
+
+Ned stepped to the mouth of the cavern and looked out. Jimmie was
+making his way back to the machine, empty handed and evidently
+dejected. Ned gave a sharp whistle and beckoned to the lad when he
+looked up.
+
+He did not care to make any unnecessary noise there, for he believed
+that Collins was not far away.
+
+He was now half convinced that Lyman had been secreted in that
+vicinity after being abducted from Paraguay; that he had been
+closely guarded and comfortably provided for, the idea being to keep
+him out of Paraguay until his concession reverted to the government.
+
+It was his notion, too, that Lyman had inhabited this cavern until
+the appearance of the Nelson, when he had been removed by his
+attendants and placed in custody in some other natural hiding place.
+
+Whether he was still in that locality the boy could not say, but of
+one thing he was certain. That was that Lyman had not been taken
+away in the motor car.
+
+And so the quest had been shifted! There would now be no need of
+proceeding to Asuncion. Probably to prevent getting mixed up in the
+crooked game, the plotters in Paraguay had ordered those interested
+in the disappearance of Lyman to get him out of the alleged
+republic.
+
+This would account for his being in the mountains of Peru. It might
+also account for the presence in Lima of the Vixen and Mr. Thomas Q.
+Collins.
+
+The telegrams without meaning which Ned had received on his arrival
+at Lima pointed out the fact that the conspirators knew that the
+Nelson was heading for that city as a base of operations. Ned's
+receipting for the telegrams was proof positive that he had arrived.
+
+"A very pretty plot!" Ned thought, as he waited for Jimmie to make
+his way up the face of the cliff to the mouth of the cavern.
+
+"Gee!" the little fellow cried, as his head showed above the level
+of the floor of the hiding place. "I never was so hungry in me
+blameless life!"
+
+Ned backed up so as to conceal the tinned food.
+
+"What will you give for a couple of tins of pork and beans?" he
+asked, with a provoking smile.
+
+"I'll sign a check for any amount!" grinned the boy.
+
+Ned stepped aside, disclosing the food, and handed Jimmie a small
+hatchet which he had found under the rubbish.
+
+"Go to it!" he said.
+
+Jimmie almost dropped with amazement. It was like getting water out
+of the desert. Like finding milk in the heart of a rock. Like
+uncovering snowballs from a bed of hot coals! American tinned goods
+in the mountains of Peru!
+
+The boy examined the cans attentively. They were all correct on the
+outside. Then he cut one open with the hatchet and brought out a
+spoonful of beans on the corner of the implement.
+
+"Wow!" he cried, in a moment. "They're all right! Come on an' fill
+up!"
+
+Both boys fell to, and the supply of tinned food was considerably
+diminished before they had finished their breakfast. Then, fearful
+that the owners of the food might seek to remove it before another
+meal time came, they carried a considerable portion of the cans away
+and hid them in a small cache near the Nelson.
+
+"We won't starve for a few days," Jimmie said, when this work had
+been finished.
+
+"Now, tell me what it all means. I wanted to ask you before, but,
+somehow, I couldn't keep my mouth empty long enough to talk. What
+about it?"
+
+"I think," Ned replied, "that we have blundered on the country
+residence of Mr. Horace M. Lyman!"
+
+"What does he come up here for?" asked the little fellow. "Ain't he
+got no sense?"
+
+"The decision wasn't up to him, I take it," laughed Ned. "The
+schemers in that crooked little country wanted to get him out of the
+way, so they wouldn't be getting into a quarrel with the little old
+U. S. A."
+
+"I don't see him anywhere around," the other said.
+
+"He doesn't seem to be on exhibition, and that's a fact," Ned
+replied.
+
+"Perhaps," Jimmie grinned, "we'd better look up this Thomas Q.
+Collins! I guess, he could lead us to him."
+
+"No doubt of that," Ned admitted.
+
+Having securely hidden the tinned food, the boys still lingered in
+the vicinity of the Nelson. The machine lay shining in the
+sunlight, seeming to look reproachfully up at the boys, accusing
+them of getting her into a very bad predicament.
+
+"Good old girl!" Jimmie cried, stroking the motors. "We'll get you
+out of this mix-up, all right!"
+
+"If we do," Ned replied, studying the ground about the machine,
+"we'll have to get cover somewhere and watch her night and day."
+He pointed to footprints close up to the motors as he spoke, and
+Jimmie began measuring the impressions in the soft earth.
+
+"They've been here since we landed, all right," the boy exclaimed,
+in a minute. "We never left these tracks. They're big enough for
+an elephant to make!"
+
+"They were made by muckers," Ned continued. "You know the kind of
+shoes the men who work in mines wear? Big ones, looking more like a
+mud scow than a shoe. They have turned some of the copper workers
+loose on us, little man."
+
+"Gee! How long will it take Pedro to get back?"
+
+"Probably three days, if he has no bad luck--if they let him come
+back at all," Ned answered.
+
+"You can take it from me that they won't let him come back at all if
+they have anything to say about it!" the lad muttered. "I reckon
+I'll have to go an' find him."
+
+"I think it will take both of us to prevent the Nelson being broken
+up," was Ned's reply. "We shall, as I have already said, have to
+guard it night and day. And, besides, we've got to keep out of the
+way of bullets and poisoned arrows."
+
+"This is a cute little excursion, when you look at it up one side
+and down the other," Jimmie grunted. "We've left Leroy in trouble
+at Lima, and we've got the Nelson all banged up. Perhaps they'll
+hang Leroy before we get back!"
+
+"Cheer up!" laughed Ned. "The worst is yet to come!"
+
+"And here it comes!" cried the little fellow, as a handkerchief
+which might once have been white fluttered above a boulder not far
+away, held aloft and waved frantically back and forth by a hand
+which could only faintly be seen.
+
+"Come on out!" Ned shouted.
+
+A figure lifted from behind the rock and stood straight up, waving a
+dilapidated slouch hat, now, instead of a handkerchief. The fellow
+wore a suit of clothes which was much too small for him, so that his
+wrists and ankles protruded a good six inches. The clothes were
+dirty and ragged too, and the man's face looked as if it had been a
+long time since it had been brought into contact with water.
+
+At a motion from Ned he advanced toward the machine. Ned thought he
+had never seen a sadder face on a human being.
+
+"Looks like Calamity!" Jimmie muttered
+
+"Have you boys got anything to eat?" asked the stranger, rubbing his
+palms over the waist band of his ill-fitting trousers.
+
+"You look like you needed something to eat!" Jimmie put in. "How
+long you been sleuthin' at us from that rock?"
+
+"Not long," was the reply, in a slow, sober tone. "Just a minute.
+I fell down a mountain not so very long ago."
+
+"Then," said Jimmie, pointing to the wound on his head, "you haven't
+got anything on me. I'm quite a hand at fallin' down precipices,
+myself!"
+
+"You didn't say if you had anything to eat," insisted the stranger.
+"I'm so hungry that I could eat a fried griddle."
+
+"Well," replied Ned, "we're just out of fried griddles, but we've
+got a tin of beans we might give you."
+
+"Slave for life if you do!" drawled the other. "I've been wandering
+in the mountains for more than a week, and am so empty that it will
+require several tins to fill me up, but if one is the limit, why--"
+
+Jimmie uncovered the cache and brought out a can of beans, which he
+opened with the hatchet and presented to the other, with a grave
+bow.
+
+"Dinner is served, me lud!" he said.
+
+The stranger did not wait for formalities. He had no knife, fork,
+or spoon, but he managed to remove the beans from the can and convey
+them to his mouth without the aid of such artificial aids to the
+hungry. He sighed when the can was empty, and wiped his hands on
+the grass at his feet.
+
+"How did you get in here?" asked Ned, then, curious to know how any
+one could have the nerve to face a mountain journey in the condition
+this man was in.
+
+"I came after the mother lode," was the reply.
+
+"Have you got it in your pocket?" asked the little fellow.
+
+"I didn't say I found it," was the grave reply. "I said I came in
+here looking for it. There was a party left Sicuani, over to the
+east, two weeks ago, and I trailed in behind. You see, I had a fool
+idea that these people were on the track of a big gold find, and so
+just naturally sneaked along. They had an automobile. I walked.
+They had plenty of provisions. I had no one to grub-stake me. They
+feasted while I starved, but the way is rough and slow, especially
+when tires break, and I managed to keep up with them until two days
+ago. Then they got away from me."
+
+"Did you find gold?" asked Ned.
+
+The stranger shook his head.
+
+"Nothing doing!" he said. "I've been grubstaked all over Australia,
+and up the Yukon, and over Death Valley, but I have never found a
+spot where there's so little gold as there is in these hills."
+
+"So, you are an American tourist?" asked Ned.
+
+"I am," was the grave reply. "I stowed away on a ship bound for
+Asuncion and got a job shoveling coal to pay for the rottenest grub
+I ever ate. When we got up the river to Asuncion I hired out to a
+man to herd cattle. That was worse, only the air was not so
+confining."
+
+"So you left and went to Sicuani?" asked Ned.
+
+"Exactly, after many days. I liked the cattle business all right,
+but I had to move on. Horace M. Lyman is a good chap to--"
+
+"Wait!" Ned said. "It was Horace M. Lyman you worked for, eh?"
+
+"Sure. He's an American, and a fine fellow."
+
+"Well," Jimmie cut in, "you're likely to see him if you stick around
+here. They geezled him, so another gazabo could get his
+concession."
+
+"And marooned him off here? Is that it?" asked the stranger.
+"Well, there's a pair of us, then, that don't find anything
+nourishing in the scenery. Where is he?"
+
+"We haven't found him yet," Ned answered, "but we're on the trail.
+If you had one more can of beans, do you think you could help us
+hunt him up?"
+
+"Certainly. Of course. I'll do that without the beans, but--"
+
+"I see," Ned answered. "You haven't the strength, just now, to do
+much looking. All right, we'll fat you up, and then--"
+
+Ned did not complete the sentence, for a long, wavering call came
+from the west, and the stranger started off in that direction
+without a word of explanation. Ned wondered for a moment whether
+this fellow wasn't another hypocrite of the Collins stripe.
+
+"Wait a minute!" he exclaimed. "Suppose you tell us something about
+that call?"
+
+"I'm agreeable," replied the other. "Don't you know what that
+coo-coo-ee-ee is? Then you've never lived in the cattle country.
+That is a cowboy salute, pard, and my private opinion is that Horace
+M. Lyman is the party that uttered it."
+
+"Then he's not far away," Jimmie said.
+
+"Suppose I answer him?" asked the stranger.
+
+"Go on an' do it," the little fellow advised, and Ned nodded.
+
+The cod-coo-ee-ee which the ex-cowboy emitted rang through the
+valley and came back in weird echoes from the crags around.
+
+"Now he knows there's some one here looking after him," the stranger
+explained. "He knows that Old Mose Jackson is right on the job.
+What might your name be, pard?" he added, turning to Ned.
+
+"Nestor," was the reply.
+
+"Ned Nestor, of course!" Jackson exclaimed. "I read about you being
+in Mexico, and in the Canal Zone. Strange I should bump into you
+away off here! And I'll bet this is Jimmie? What?"
+
+"The same!" the little fellow replied. "Ned can't lose me!"
+
+Hardly had the words left the boy's mouth when a bullet came zipping
+through the air. It struck a metal section of the Nelson and
+flattened out.
+
+"Before now," Jackson said, coolly, "when I've found myself on the
+open plain with redskins popping away at me I've dug a hole in the
+ground and stowed myself away in it. What do you think of the
+notion, pard?"
+
+"It looks good to me!" Jimmie cried. "But," he went on, "We've got
+nothing to dig with, so we'll just have to move back to that gully,
+an' take the grub with us."
+
+The change was soon made, the Nelson being run back to the edge of
+the trench-like depression, and then the three awaited the next move
+on the part of the enemy.
+
+Presently a shout was heard, and then the flashily-dressed figure of
+Mr. Thomas Q. Collins appeared on the shelf of rock.
+
+"Don't shoot!" he cried, swinging both hands aloft. "I want to come
+down and talk with you."
+
+"There's some trick in that!" Jimmie said.
+
+
+
+
+
+CHAPTER XI
+
+A STICK OF DYNAMITE
+
+
+"If we could only get out of this cul-de-sac," Jack said, as the
+savages gathered closer about the Black Bear, "and make the Beni
+river, we could leave them behind like they were painted on the
+trees."
+
+"There ought to be some way," Frank mused.
+
+Harry, who had been rummaging in a trunk of clothing and tools which
+stood under the bridge which half concealed the motors, now came
+forward with a package in his hand.
+
+"What is it?" asked Jack.
+
+"Dynamite!" was the cool reply.
+
+"That ought to induce them to go on about their business--if
+properly administered," Jack said. "I didn't know we had any on
+board."
+
+"I didn't know what we might come across up here," Harry replied.
+"Shall we light a fuse and give one of these persuaders a toss over
+into that mess?"
+
+"It would amount to wholesale murder," Frank replied.
+
+Harry's face hardened as he held up a hand for silence. The howling on the
+banks of the little stream was now almost deafening, and every second there
+came the thunk of arrows against the boat.
+
+"You see what they would do to us," he said.
+
+"Yes, I know," Jack said, "but we are supposed to be civilized! It
+would be a wicked thing to do, to murder fifty or a hundred of those
+savages. Suppose we toss a stick where it will do little damage and
+still attract their attention from the boat? Then we might get that
+log out of the way."
+
+"We'll see what show we have for getting it out of the way-the log,
+I mean," Jack replied.
+
+He cautiously opened one of the lower panels at the rear and looked
+out. The log which blocked the narrow channel was afloat, for it
+was the trunk of a dry tree, and the water was deep. What held it
+in place was the end which lay on the shore. It had been rolled in
+at a point where the bank was low, and at least two-thirds of it lay
+on the ground.
+
+"I'd like to know how they got it in there!" Jack said. "It looks
+too big for a hundred men to handle."
+
+"Anyway, there it is," Frank replied, "and there the propellers
+are--one of them broken. Can we make speed with that busted wing?"
+
+"We've got to," Harry said. "Just hear the devils! They will rush
+the boat in about a minute!"
+
+The cries coming from the forest were now blood-curdling in their
+ferocity. The cannibals were evidently working themselves into a
+pitch of excitement which would give them courage to charge the
+Black Bear.
+
+Now and then the frightened howl of some wild beast was heard in the
+distance, adding not a little to the excitement of the scene. The
+tree which had been set on fire to attract the attention of the
+airship still blazed, sending a twist of flame far up into the sky.
+
+In the glare of the fire the savages looked like fiends ready for
+any act of deviltry. Now and then three figures larger than the
+rest stood together as if in conference, and then the shouts grew
+louder, and the line about the boat closer drawn.
+
+"I've got a notion that we can make pretty good speed with that
+broken wing," Jack mused. "Anyway, we can drift down stream if we
+can't steam up stream, and that will take us out of this mess."
+
+"Then let's blow that log up with dynamite," suggested Frank.
+
+"Yes," said Jack, "and finish the propellers!"
+
+"Blow up the shore end," continued Frank. "Who can pitch it so that
+it will knock that blooming dry wood into the stream?"
+
+"I'm willing to try," Harry said. "I used to pitch a tricky ball!
+I'll get a fuse ready, open a panel, and give it a throw. While I
+have the panel open, though, you fellows open up a loophole in front
+and do some shooting out of it to attract attention. I don't want
+any poisoned arrows biting me."
+
+This was agreed to, and Harry arranged a fuse and prepared to throw
+it. When Jack opened a panel in front and sent a volley of bullets
+ashore, the boy pushed open a panel in the rear and, waiting until
+the attention of the savages was attracted to the front of the boat,
+tossed out the dynamite.
+
+It hurled through the air, flashing in the red light of the fire,
+and landed at the very end of the fallen tree, rolling into the
+angle between the wood and the earth. A fine throw!
+
+Harry yelled to Jack to close his panel, and all three boys stood on
+the tips of their toes, fingers in ears. In a moment the explosion
+came.
+
+The Black Bear rocked violently, so that it was with difficulty the
+boys kept their footing. Wild cries of distress and fright came
+from the forest, and, in a few seconds, the crash of falling trees.
+The dynamite had done its work well, at least, so far as noise was
+concerned. They could not yet see what effect the explosion had had
+on the tree.
+
+Had it loosened the obstructing log so that the boat could pass out
+into the Beni river? Had the concussion damaged the propellers so
+that the trip up the valley of the Amazon would have to be
+abandoned?
+
+These questions were in the minds of all three boys as Jack
+cautiously opened a rear panel and looked out. The first thing he
+saw was the log, splintered and broken into half a dozen pieces,
+floating down stream.
+
+The explosion had whirled the great trunk high up in the air and
+brought it down, broken, in the channel of the stream. There seemed
+nothing to do now but to set the motors at work and run out of the
+dangerous position.
+
+But the motors refused to work. Something more than showed on the
+surface was the matter with them. Harry looked out at the rear and
+saw a great red patch of earth without a single human being in
+sight. The fire was still burning brightly, but there were no
+savages dancing about in its fierce light.
+
+At the sound of the explosion the head hunters had taken to their
+heels. At first view, no one seemed to have been injured by the
+dynamite, but, on giving the scene a closer inspection, the boy saw
+three bodies lying near where the log had been. They might be dead
+or only stunned; the lad had no means of knowing.
+
+While Harry watched for some sign of life, the roar of a wild animal
+came from the forest, and he knew that a tiger cat was approaching.
+The humans--if the man-eating savages may be so termed--were still
+running, it appeared, while the wild beasts of prey were returning
+to the scene of the explosion.
+
+"Come," Harry cried, "we must get out of this now if we can get the
+propellers to working. There is no one in sight, only three men
+lying near where the log lay, and there are man-eating animals
+coming, so I'd rather not see what takes place next."
+
+Jack threw open another panel and stepped out. The roar in the
+forest was growing again, but no savage was in sight. He moved to
+the back of the boat and bent down to look at the propellers.
+
+"I can't see from here!" he shouted, in a moment. "Look out for me,
+you fellows!"
+
+Like a shot he was in the river, diving under the stem of the Black
+Bear. Harry and Frank, knowing the rivers of that district to be
+swarming with caymen, grouped at the rear and watched with anxious
+eyes for the reappearance of their chum.
+
+In a few seconds Jack's face appeared above the surface of the
+water. He seized a rope passed to him and climbed on board, shaking
+the water from his clothing like a great dog.
+
+"It is all right," he said, as soon as he could get his breath.
+"There was a piece of the log wedged in back of the paddles and I
+got it out. Get a pole and push. She's in the mud, I guess."
+
+The pole was used before the motors were turned on again, and the
+Black Bear was soon out of the little creek, sailing slowly down the
+Beni. However, the boat did not behave well, and it was decided to
+tie up for a day and go over her carefully. The propellers needed
+fixing, and there might be some other injury which had not been
+discovered.
+
+Not caring to strain the weakened propellers, they permitted the
+boat to drift down stream.
+
+When a mile away the illumination of the fire which had been so
+injudiciously set could still be seen distinctly, and when the boys
+listened they could hear the cries of the savages and the fierce
+howls of the wild beasts.
+
+During the day the boys had passed a level plateau on the east bank
+of the river, and it was decided to float down to that, as they
+could beach the Black Bear there and work without danger of being
+attacked from the shelter of a forest.
+
+They gained the spot about midnight and anchored some distance out,
+resolved to take no chances on the shore that night. The stream was
+quite wide, and they opened the top panels so as to get what fresh
+air they could.
+
+Jack was the first one to see the airship hovering over them.
+
+"Look!" he cried. "Look! Look! We've just got to attract their
+attention in some way! See! They are going away again! Confound
+the luck!"
+
+The airship seemed about to dip down, then it floated off to the
+west and whirled to the south.
+
+"They're signaling!" Harry cried.
+
+This seemed to be true, for there were lights moving about in the
+air in queer combinations.
+
+"Get a glass!" shouted Jack, in great excitement. "We'll soon see
+about this!"
+
+But the airship seemed interested in the spot where the fire was
+burning, and did not remain overhead long enough for the boys to get
+a good view of her. At last she disappeared entirely.
+
+Although anchored out in the stream, which was at least two hundred
+feet wide at that point, the lads kept a close watch of the shores
+that night. Once, just before dawn, they caught the sound of
+paddles, but the canoe which appeared on the west soon sneaked away.
+
+The hubbub on shore kept up all night long. The beasts took up the
+chorus when the savage tribesmen retreated.
+
+"Beautiful country this!" Jack said, as the, sun rose over the great
+valley. "I think I'll like to live here always--not!"
+
+"Yes," grunted Frank, whose eyes were heavy with the long watch,
+"even on the Great White Way, the enthusiasm quiets down after three
+o'clock."
+
+"It is all in the game!" grinned Harry. "We came out here for
+excitement, and you mustn't complain when you get it."
+
+After breakfast, which was keenly enjoyed, the Black Bear was
+beached on the cast banks and the injury to the propellers examined.
+Some of the blades were broken while others were strained.
+
+"Well," Harry said, as he scratched his head in deliberation, "we've
+got extra blades, and we've got the tools, and I don't know as we're
+in a hurry anyway. We've got all the time there is!"
+
+"Not if we catch the Nelson before it gets out of the country," Jack
+objected. "This is the 22d of August, and the Nelson must have
+sighted Lima about the 14th, so you see we've got to do some sailing
+if we get to the headwaters of the Beni before the boys get back
+home."
+
+If they had only known, the lads might not have been so anxious to
+get on, for the boys with the Nelson were having troubles of their
+own about that time. Besides, there were difficulties ahead much
+greater than those entailed by the breaking of the blades of the
+propellers.
+
+They worked all day at repairing the injuries, and at night were
+ready to proceed. It was dark again, and there seemed to be a great
+commotion on shore.
+
+"For one," Frank observed, "I don't like the idea of going on up an
+unknown river in the night. There are rapids, and there may be
+obstructions. And then we may follow off some tributary which will
+land us in some swamp after an all night ride."
+
+"I'm not anxious to go on tonight," Harry contributed, "for I'd like
+to see what that mess on shore will amount to. There's something
+besides the appearance of the Black Bear exciting those fuzzy little
+natives, and we may miss something if we run away. I wouldn't like
+to do that."
+
+So it was decided to remain where they were until morning. The
+panels were put up, leaving only the openings for ventilation, and
+the Wolf was brought close alongside.
+
+Frank got the first watch in the drawing of sticks, and stationed
+himself at the prow, where he could look out on the river. Jack and
+Harry were soon asleep.
+
+About midnight a great clamor arose on the west bank. In a moment
+it was echoed from the opposite shore. There was a beating of
+drums--the foolish drums which the natives made so crudely--and long
+chants, rising in the darkness like the monotonous melodies the boys
+had heard in the cotton fields of the South.
+
+Frank shook Jack and Harry out of their bunks, much to the disgust
+of the two sleepy-heads. They did not need to ask questions as to
+the reason for this, for the chant was coming nearer, and the drums
+were beating like mad.
+
+"They're arranging an attack!" Jack said, turning a searchlight out
+of the front loophole. "I can see half a dozen canoes hanging off
+and on at a bend above. I guess we made a mistake in stopping
+here."
+
+"Perhaps we'd better drop down the river," Harry suggested. "I
+don't want those heathens swarming over the Black Bear."
+
+Jack went to the stern and looked out on the swirling river from
+that point.
+
+"If we do," he said, in a moment, "we'll bunt into a fleet of war
+canoes. We've got to put on all speed and drive ahead."
+
+"Why not drop back?" asked Harry.
+
+"Because," was the reply, "we can go up stream about as fast as we
+can go down stream, and the canoes can't. We'll shut everything
+tight but the loopholes and go through them like a shot through
+paper. If they board us we'll have to open up and drop them into
+the river with our automatics."
+
+"Put the big light out in front then," Harry said, "and stand there
+and tell me which way to steer, and let her go!"
+
+The next moment the Black Bear, closely followed by the Wolf, was
+nearing the canoes, now drawn up in line of battle in front.
+
+
+
+
+CHAPTER XII
+
+A BRIBE OF HALF A MILLION
+
+
+"What do you want to talk about?" asked Ned, as Thomas Q. Collins
+advanced a step, both hands still high above his head, as an
+indication that he was unarmed.
+
+"I want to reach an understanding with you," was the reply.
+
+"About what?"
+
+"About--well, about your errand here."
+
+"Oh! Well, what about it?"
+
+Collins hesitated a moment and then asked:
+
+"Why can't I come to you and sit down? I'm not armed. This is not
+an easy or a dignified position for me to hold."
+
+"You say you are not armed," Ned replied. "Will you say as much for
+the savages who are with you in this dirty game?"
+
+"There are no savages here with me," Collins protested. "Your
+Indian killed one by throwing him from the ledge, one was killed
+when the Vixen burned and dropped, and one was shot by one of your
+boys. The other went away with the motor car. You must have seen
+them riding away?"
+
+"There were five people with him when he first came out here in the
+car," Jackson said, under his breath. "Ask him where the other
+white man now is."
+
+"Did you see the other white man?" asked Ned of Jackson.
+
+"Not distinctly."
+
+"Would you have recognized him if it had been Lyman?"
+
+"I might. I can't say. I wasn't very near to them. They kept me
+scouting over the hills to keep them in sight."
+
+"Well," Collins called out, impatiently, "are you going to let me
+come in for a talk? If not, I'll go back and bring some shooters
+out here."
+
+Without answering that special question, veiled, as it was, with a
+threat, Ned asked the one proposed by Jackson.
+
+"Where is the white man who was with you when you first came here in
+the car?"
+
+"I did not come in a motor car," was the reply. "I came in the
+Vixen."
+
+"That's a lie!" Jackson whispered. "The Vixen, if that is what they
+call their airship, never showed up until a few days ago. I tried
+to signal to the driver; or, rather, I did signal to him, but he
+ignored me. This man Collins came in with the car more than two
+weeks ago, and went out in it, too, and the other white man
+remained. The next time he came, he was in the Vixen."
+
+"Who is that fellow who is filling you with prejudice against me?"
+demanded Collins, presently. "It looks like a man wanted for
+stealing cattle from the Lyman ranch."
+
+"Why didn't you communicate with him, if you were so hungry?" asked
+Ned of Jackson, suspiciously. "You say he has been here at least twice."
+
+
+Jackson frowned and looked away. Then his forehead flushed and he
+said:
+
+"I guess there's no use lying about it. I was accused of running
+cattle off the Lyman range. That is the man who accused me. I
+never did. He knows that. Now you know why I didn't approach him
+and ask for food."
+
+"Well," insisted the boy, "why didn't you browse around and find the
+white man he left here? That is what he came in here for, isn't it--to
+hide some one he wanted out of the way?"
+
+"I thought he came to look for gold," was the reply. "Now, about
+the other question. I did try to find the man he left here. I
+wanted to eat with him! I knew there was some one in the hills, but
+I never found him. It beats the Old Scratch where he is!"
+
+"Come, come!" Collins cried, impatiently, "you can do your visiting
+after we have our talk. Shall I come to you, or will you come to
+me?"
+
+"Don't you go out there!" Jimmie warned. "He's got some one hidden.
+You'll be shot if you do. Tell him to come here."
+
+"Keep your hands up and come here," Ned ordered, thinking this good
+advice.
+
+He had already experienced the treachery of the fellow, and did not
+care to take any chances. Collins came along sullenly, stood stock
+still, while Jimmie searched him, and then sat down on the framework
+of the Nelson.
+
+"That aeroplane would look handsomer," Ned said, grimly, "if your
+men had not set it on fire."
+
+"That was war!" Collins replied. "It is war still, unless we can
+come to some kind of agreement."
+
+"I haven't much faith in your word," Ned replied. "You played a
+dirty game on me at Lima, you know."
+
+"The chances of war!" Collins replied. "Now," he went on, "we can
+come to terms without any reference to the International Peace
+Congress, if we want to. I'll admit that if things were a little
+different I wouldn't be asking for terms, but that is neither here
+nor there. I want your assistance."
+
+"On the level?" demanded Jimmie.
+
+Jackson grinned scornfully, and Collins glared at both.
+
+"The man we brought out here--merely as a matter of business--has
+disappeared," Collins went on. "We left him in the little cavern
+where you found his coat and the food. He's got away."
+
+"You refer to Lyman?"
+
+"Of course."
+
+"You were keeping him a prisoner until his concession should lapse?"
+
+"That's only business."
+
+"When does it lapse, in case he does not appear and make payment?"
+
+"On the 31st of August."
+
+"And this is the 18th?"
+
+"I think so. I'm pretty well mixed as to time, as well as
+everything else."
+
+"Then he has only fourteen days in which to get back to Asuncion and
+make a large payment?"
+
+"That is just it."
+
+"And he is lost?"
+
+"Yes."
+
+"When did you see him last?"
+
+"You remember how I came to be here? You brought me, trussed up
+like a hen in that aeroplane harness. Well, when the Vixen went
+into that pit and you went away to look over the scenery, I knew
+that the motor car would be along soon, so I didn't try to get away.
+I knew what would happen if I did. You'd shoot! Just as soon as
+the car came and I was released--the car brought in food for Lyman--
+I sent a man over to the cave to find Lyman. He wasn't there.
+Understand? He wasn't there."
+
+"But there were live embers in the cave when I got there," Ned said.
+
+"I know. That was built by one of my men, who wanted to make
+coffee, but didn't. The food you stole was brought in by the car as
+I said before. You found Lyman's coat, didn't you?"
+
+"Yes, and a packet of letters."
+
+"I knew what you were in Lima for from the first. I knew of your
+mission before you left San Francisco. So I did not lie to you when
+you asked if the man who was brought in, something over two weeks
+ago, in a motor car was Lyman. I knew that you knew. You see, we
+had to get him out of Paraguay when it was learned that the United
+States had placed the Lyman affair in the hands of the Secret
+Service."
+
+"Go on," Ned said. "You are getting pretty close to the point now."
+
+"I thought at first," Collins went on, "that you had blundered into
+this district just by blind luck. Now I know better. I gave myself
+away by my fool antics at Lima. Then the Vixen showing up and
+chasing the Nelson around increased your suspicions. Oh, I know how
+it happened. You fooled us all. We led you right to the spot where
+Lyman was hidden by our attempts to mislead you. More fools we!"
+
+"You have stated the case correctly," Ned said. "If you had kept
+away from me at Lima, and the Vixen had kept out of sight, I should
+have gone straight on to Asuncion, and should have been wasting my
+time there this minute."
+
+"Yes, that's the truth! Well, now I've been perfectly frank with
+you, and I want you to be equally honest with me. Do you know where
+Lyman is?"
+
+"I do not."
+
+"You haven't seen him?"
+
+"Never saw him."
+
+"If you find him, what do you propose doing?"
+
+"I shall take him back to Asuncion and see that he gets justice."
+
+"Acting as a Secret Service man of the United States?"
+
+"No, as an individual."
+
+"But you are in the employ of the government?"
+
+"Yes, but I'm not authorized to mix the two countries up in a war."
+
+"Yes, I know, but your government will back you in whatever you do.
+That is the point with me. If you report no cause for interference
+down in Paraguay, there will be no danger of our getting into
+trouble. Your government wouldn't make a demand for Lyman's
+release, although it was understood he was kept in duress by a high
+official of the republic. Still, it sends you out to act
+unofficially. Now, this being the case, you are the person I want
+to talk with."
+
+"Well?"
+
+"I want you to help find Lyman, and then I want you to help me come
+to terms with him--we can't fight the United States!"
+
+"In other words, you want me to betray my trust and help you rob
+him?"
+
+"No. There are two sides to everything--where there are not three,
+or more. So there are two sides to this cattle concession business.
+I think that Lyman will be glad to settle if we find him--if he does
+not know that the United States has Secret Service men on the
+ground!"
+
+"So you really do want to buy my silence?"
+
+"I want to make sure that you will not attempt to defeat our plans."
+
+"Nothing doing," Ned replied.
+
+"Wait!" Collins continued. "You haven't heard me out. We'll see
+that Lyman gets all his money out of the deal, with something
+besides, and also that you get a quarter of a million dollars for
+saying nothing."
+
+"Nothing doing!" Ned repeated.
+
+Collins actually gasped with amazement. He had offered bribes
+before, but had never started out with so large a sum. And he had
+never been denied!
+
+"Understand the proposition," Collins said, presently, as soon as he
+could catch his breath, "it is not you we want. We don't care a
+continental cuss for you. What we want is for you to keep quiet
+after we find Lyman. It is the Secret Service of the United States
+we axe afraid of. I'll make it half a million."
+
+"It must be a rich concession," Ned said.
+
+"It is, and Lyman got it for a song, for no one ever supposed that
+swamp would make good grazing ground."
+
+"I guess Mr. Lyman will earn all he gets out of it," Ned laughed.
+
+"He will never get anything out of it, unless he comes to terms with
+me," Collins said, impatiently. "We'll find some way to keep him
+out of Asuncion until after the 31st. It is a long way from here to
+Paraguay!"
+
+"All the more reason why we should get busy looking for him," Ned
+said.
+
+"And when we find him?" asked Collins, tentatively.
+
+"I shall take him back to Asuncion."
+
+"Then you'd better not find him," threatened Collins. "If you're
+going to oppose me, I'll leave it to you to look him up. I'll go
+back to Asuncion and bring men out here who will see that you never
+leave the mountains."
+
+"Gee! That's a cheerful proposition!" grinned Jimmie.
+
+Collins, disgusted at his failure to either bribe or frighten the
+boys, started away, but Jackson laid a heavy hand on his shoulder
+and swung him around.
+
+"Wait a minute!" he said.
+
+"What do you mean?" demanded Collins.
+
+"You're not going to Asuncion after help," Jackson said. "I have a
+little score to settle with you myself! You're the man who accused
+me of running off cattle. Well, you're going to remain right here
+with me until I go out with you and give you a chance to make that
+right."
+
+Collins glanced at Ned.
+
+"Is this by your order?" he asked.
+
+Ned shook his head.
+
+"I have no present quarrel with you," he said.
+
+Collins started away again, but Jackson thrust him back, not any too
+gently.
+
+"If you make a touse," he said, "I'll tie you up. Now," he added,
+as Collins, almost foaming with rage, threw himself on the ground,
+"I want you to tell me where you left that tent."
+
+Both Ned and Jimmie sprang to their feet at the mention of the word.
+
+"A tent! Here!"
+
+Collins snarled out some impertinent reply, and Ned asked:
+
+"Did they bring in a tent?"
+
+"You bet they did!" Jackson answered. "This fine-haired duck with
+the circus parade clothes wasn't going to sleep in no cavern. He
+was going to have a nice, soft, cool bed under a tent while he was
+waiting for the Lyman concession to lapse. He was reared a pet--he
+was!"
+
+The ex-cowboy was so enraged at Collins for the insinuations he had
+cast upon him that he pushed up to where he lay and would have
+assaulted him if Ned had not interposed.
+
+"Let him alone," the boy said. "We'll leave the law to make payment
+in his case. Are you going to tell us where the tent is, Collins?"
+he added, turning to the angry captive.
+
+"I guess you can get along without the tent," Collins said. "You
+won't have to remain here long. I've got men coming in. They may
+be here at any moment. Officers of the Republic of Paraguay!"
+
+"I shall be glad to meet them!" Ned laughed. "If you'll tell me
+where the tent is I'll be able to entertain them properly."
+
+"Aw, I can find the tent if it is around here anywhere!" Jimmie
+broke in.
+
+"What do you want of it?" demanded Collins
+
+"A little tent cloth," Ned smiled, "would make a serviceable machine
+of the Nelson. We could make new planes in no time. What do you
+think of the idea?"
+
+"I'm not going to have the tent cut up," shouted Collins.
+
+"I guess yes," Jimmie said, provokingly. "You burned our planes,
+and you've got to supply material for new ones."
+
+The little fellow darted away as he spoke, working his way over the
+ledges which separated the two dents on the mountain sides. In a
+short time Ned heard him calling and saw him looking down from the
+shelf above the cavern.
+
+"Come on up," the lad cried. "I can see the tent over in the other
+valley, and there's another automobile coming. What do you think of
+that? This must be a regular station on the underground railroad
+between Asuncion and Lymanville!"
+
+Ned lost no time in gaining the ledge. The white body of the tent
+was in plain sight, just where the men had dropped it out of the
+machine. The two boys hastened into the depression, seized the
+canvas in their arms, and started back toward the Nelson. On the
+shelf again, Ned asked:
+
+"Where did you see a motor car?"
+
+"Over east," was the reply. "There's a tunnel under the range off
+that way. I take it that a river ran there once, draining this
+valley."
+
+Presently the machine appeared in the valley from which the Vixen
+had slipped off into the pit. There were four men in the two seats.
+One was the Indian in goggles who had driven the car away, the
+others were white men. The car could not have gone far, so these
+men must have been picked up just outside.
+
+The boys carried the canvas down to the Nelson and began the work of
+making new planes, keeping close watch, but leaving the newcomers to
+do the calling if there was any to be done. There was plenty of
+canvas and the tools necessary for the work were found in the
+Nelson's tool chest. Collins watched the doings angrily.
+
+"These men," he finally said, "are officers. Two from Paraguay and
+one from Peru. They have warrants for your arrest."
+
+He started to his feet as if to join the others as he spoke, but
+Jackson saw that he did not get very far.
+
+"Tell your friends," Jackson said, "that we're too busy to be
+bothered now. We'll soon have this aeroplane fixed, and then we'll
+give an imitation of men sailing out of this mess. Lyman knows a
+friend is here, for he heard my cowboy call. He will soon come out
+of his hole, and we'll take him back to Asuncion--just to prevent
+international complications!" he added with a grin.
+
+The work of preparing the new planes progressed swiftly, but before
+it was completed the men who had arrived in the automobile appeared
+on the ledge and called down to those below.
+
+
+
+
+CHAPTER XIII
+
+THE NELSON IN THE SKY
+
+
+"Well," Ned called back, as the new arrivals shouted down from the
+ledge, "what do you want?"
+
+"We want to talk with you."
+
+"Cripes," Jimmie grinned, "we're in good demand today. The stock of
+Boy Scouts must be gettin' shy!"
+
+"Go on and talk, then," Ned answered, well satisfied as to what the
+fellows wanted.
+
+"Shall we come down there?"
+
+"You stay away!" Jimmie replied. "We're a little particular about
+our company!"
+
+"Is that little runt speaking for you?" demanded the man on the
+ledge. "If he is, we'll do something besides talk."
+
+"For the present he is," Ned replied. "What can I do for you?"
+
+"You can surrender yourself. We have warrants for your arrest."
+
+"Couldn't think of it!" was the cool reply. "We prefer to remain at
+liberty."
+
+"I told you!" Collins grunted, rising from his reclining position
+and moving toward the ledge. "I told you that you'd get into
+trouble. You'll sweat for this!"
+
+Jackson caught him by the shoulder and whirled him back.
+
+"You stay here!" the ex-cowboy gritted. "The less trouble you make
+the better treatment you will receive."
+
+"What are you doing to Collins?" asked the newcomer. "Tell him to
+come up here."
+
+"I'm being held a prisoner!" Collins shouted. "Train your guns on
+these kids and drive them off. And find Lyman. He left the cavern,
+but he's somewhere about, for he answered a cowboy call not long
+ago."
+
+"We already have Lyman!" was the answer. "He thought we were the
+friends who had called him and joined us. We'll take care of him,
+all right."
+
+"That's fine business--not!" grunted Jimmie.
+
+Ned was not a little disappointed by the announcement. With Lyman
+in the hands of his enemies, it might be impossible to get him back
+to Asuncion in time to save his concession.
+
+And here was another difficulty, one which might bring on a war
+between the United States and Paraguay. Ned, as an official of the
+United States Secret Service, now knew that those high in authority
+in the government of Paraguay were involved in the attempt to
+defraud Lyman of his rights. This had been only suspected before.
+
+So long as only private interests were interfering with the treaty
+rights, so long as the government of the unruly republic was not
+mixed up in the attempt to cheat an American citizen out of his
+property, the government at Washington might well restrain its hand.
+But when the government of Paraguay itself, as Ned now believed, was
+involved in the crooked game, that was an entirely different matter.
+
+Ned believed that a full disclosure of the facts in the case would
+send warships to Asuncion. He believed that an international
+complication might breed open war unless he succeeded in getting
+Lyman away without open conflict with the authorities of the little
+republic. But how?
+
+Well, the State Department at Washington had trusted him, and he
+would do his best. The thing to do at that time, it appeared to
+him, was to await the action of the newcomers. They might be
+officers of Paraguay, with authority to make arrests in Peru, and
+they might be only four-flushers. He must temporize until he found
+out what they proposed to do in the matter.
+
+And, then, he reasoned, if they had Lyman, he had Collins! That was
+not so bad! Perhaps an exchange of prisoners might be made! This
+did not seem very likely, but still there was hope. Collins, for
+all he knew, might be the man who expected to profit by the robbery
+of the American cattleman.
+
+"So Mr. Lyman is there with you?" Ned called back. "Send him over
+here. I want to talk with him."
+
+A harsh laugh was the only answer to this.
+
+"You may as well come to terms with me," Collins exclaimed. "You
+have no chance of winning now. I like your nerve, but you're
+butting into too strong a game for a lad of your years."
+
+"I shall have to take chances," Ned replied. "What will those men
+do with Lyman?"
+
+"I don't know!"
+
+"I know!" Jimmie cried. "They'll kill him!"
+
+"I don't think they'll do that," Collins remarked, with a wicked
+sneer, "but it would clear the atmosphere if he should fall down a
+mountain!"
+
+"If he does," Ned declared, flushing with anger at the brutality of
+the remark, "you will also take a tumble. If he is injured in any
+way, you'll answer to me for it."
+
+"You wait!" warned Collins. "I've handled cases like this before.
+I can give you cards and spades and beat you out. You'll be getting
+hungry before long."
+
+"And the Nelson will be ready for flight before long," Ned replied.
+
+During all this conversation Jackson and Jimmie had kept steadily at
+work sewing the new, strong canvas taken from the tent on the frame
+of the planes. They could not make a very neat job of it, but they
+did their work well. Ned had hope of getting out of the valley that
+very night. Presently the men on the ledge withdrew for a time, and
+Ned began a closer examination of the Nelson. To his disgust he
+discovered that the gasoline was very low in the great tanks. Built
+for long flights, the Nelson's tanks were very large, fitted to
+carry a supply which would last a couple of days. Ned did not quite
+understand why the supply should be short after a run of only three
+or four hundred miles.
+
+"I've got an idea!" Jimmie said, catching the worried look on Ned's
+face.
+
+"I'm afraid it will take something more than an idea to get the
+Nelson back to Lima," Ned replied in a low tone, for he did not care
+to have Collins informed of this new difficulty.
+
+Collins, however, had been watching the movements of the boys
+closely, and at once surmised what the trouble was. He laughed
+insultingly as he pointed to the great tanks.
+
+"Empty?" he snarled. "I knew it. Now will you be good!"
+
+"Shut up!" raged Jackson, who was only too anxious to get a pretext
+for attacking Collins. "We've heard enough from you!"
+
+"'Tie him up!" ordered Ned. "He's likely to make a run for it, and
+then we should have to shoot him. Tie him up good and tight."
+
+"You'll be sorry if you do!" threatened the captive.
+
+Notwithstanding this threat, the fellow was bound hand and foot.
+During the process of the work, which was performed none too gently
+by Jackson, Collins called out to his friends in the other valley,
+but there was no response. They were probably too busy with their
+plotting against the boys to hear the shouts.
+
+This business completed, Jimmie beckoned Ned aside.
+
+"Here's my idea," he said. "The Vixen's tanks didn't blow up when
+she burned and dropped. When it comes night I can go and get the
+gasoline. The tanks were full, were they not?"
+
+"Yes, chock full. The driver seemed to have fitted her out for a
+long run. But we may be able to get the stuff before dark. The
+Vixen did not land in the valley where they are, but in a canyon
+over to the west. Suppose you go over there and see what the
+chances are?"
+
+"All right!" replied the boy. "And if the tanks of the Vixen are
+not full, we'll steal the fuel out of that automobile when it gets
+dark!"
+
+"That's a good idea, too!" laughed Ned.
+
+Jimmie hastened away, keeping in the gully as long as possible and
+dodging around friendly cliffs when it came to climbing over the
+ridge which shut in the valley on the west. The gully cut across
+the valley, east and west, and was very deep at the east end.
+
+After the disappearance of the boy, Ned removed Collins to the deep
+end of the cut and placed Jackson there as a guard. He did not want
+the captive to know what was going on, as a shout to his friends, if
+they again visited the ledge, might put them in possession of the
+facts regarding the empty tanks of the Nelson. Then it would be an
+easy matter for them to prevent the getting of the gasoline from the
+wrecked Vixen.
+
+Then Ned, hearing no more from the alleged officers, went to work on
+the planes, and succeeded in getting a long strip sewed in before
+Jimmie returned with his report.
+
+"The tanks are almost full," the lad said, "and all we've got to do
+is to unscrew a couple of burrs and lug them right over here. We
+can't do that until, after dark, for they would shoot at us.
+Where's Collins?"
+
+Ned pointed to the gully.
+
+"Well," the boy continued, "when I got up on that ridge, I could see
+the men over in the other valley. They are getting reinforcements
+from somewhere. Anyway, I saw half a dozen Indians standing around.
+They've got a fire and are cooking dinner. Then I saw one of the
+white men pointing, and I'll tell you right now what they're going
+to do! They're going to station men around this little old crater
+and keep us in here until we starve, unless we give in."
+
+"They forget that there's an air route," laughed Ned.
+
+"Suppose we get up there on the Nelson!" exclaimed the boy. "And
+suppose they shoot us off! That wouldn't be funny, would it?"
+
+"We've got to go in the night, then," Ned said. "But before we go I
+want to have a talk with those fellows."
+
+"Then you'll get a word with Lyman, if you can?"
+
+"That wasn't a bluff, then? They have captured him again?"
+
+"Oh, yes, they've got him with them, all right. Anyway, there's
+four white men, and only three came in the car. Guess it's Lyman,
+sure enough!"
+
+"What is he doing?"
+
+"Just walking about. They haven't got him tied up, at least the man
+I took for Lyman isn't. He looks mad enough to bite nails, though!"
+
+"That is a wonder," Ned said. "It may be that they are trying to
+make terms with him."
+
+"Of course!" replied the boy.
+
+Along in the afternoon one of the alleged officers appeared on the
+ledge again. He appeared to be somewhat excited, and Ned suspected
+that something had gone wrong with the other party. However, he
+remained quiet, waiting for the other to make his errand known.
+After a short silence the fellow asked:
+
+"What has become of Collins?"
+
+"He is still here," Ned answered.
+
+"Held against his will?"
+
+"Well, he is still doing some kicking."
+
+"You'll be sorry if you don't let him go."
+
+"How will you trade prisoners?" asked Ned. "Send Lyman down here
+and we'll send Collins up to you."
+
+"Oh, Lyman doesn't want to leave us," was the reply. "We've
+arranged a settlement with him."
+
+Ned did not believe this. He knew that the Lyman concession was a
+valuable one, and that the cattleman would put up a long fight
+before sacrificing it.
+
+"Send him down here then," Ned answered. "If he is voluntarily
+staying with you, he can return if he wants to. Send him down!"
+
+"He is afraid you'll try some trick on him," was the reply.
+
+The whole afternoon passed in just such conversation as this--talk
+which brought no results worth mentioning. Ned did not believe that
+Lyman was remaining with the newcomers voluntarily. He did not
+believe that Lyman was suspicious of him.
+
+The men in the other valley frequently visited the ledge and talked
+with Ned, but the boy saw that they were quietly making arrangements
+to surround him. Now and then the figure of an Indian appeared on
+the elevations about the valley, which was the crater of an extinct
+volcano.
+
+A little study showed Ned that in some long forgotten time the two
+valleys had formed a great crater, and that this had been cut in two
+by the elevation of a mass in the center. High up above this dead
+crater, on the north, stretched the bulk of the mountain, the
+eruption having taken place on its south slope.
+
+But while Ned talked with the visitors, argued with them,
+threatened, he kept at work on the planes, and at nightfall had them
+completed. The canvas had been put on double and sewed on very
+strongly, so the boy believed that it was as good a machine as ever
+that he contemplated getting out that night.
+
+"But," argued Jimmie, when the plans were laid, "we can't all go in
+the Nelson. How are you going to carry Lyman, Jackson and me?"
+
+Jimmie thought for a moment and then added: "But we haven't got
+Lyman yet. We'll have to come back after him, I take it, after we
+land Jackson outside."
+
+"But I'm going to get him," Ned replied, "if this machine works all
+right. I'm going to leave you and Jackson here. What about that?"
+
+"If you can grab Lyman," Jimmie grinned in disbelief, "I'll be
+willing to stay here as long as the grub lasts!"
+
+"I'm going to get him," Ned replied. "I don't know how, but I've
+just got to get him back to Asuncion before the 31st."
+
+"And what about Collins?"
+
+"We'll have to let him go. When I get out, let him go, and then you
+two will have to hide away until I can come back after you."
+
+"All right," replied Jimmie, with a sigh. "Only hurry back! I
+don't want to starve to death here."
+
+After dark Ned, Jackson and Jimmie lugged the tanks of the wrecked
+Vixen over to the valley and dumped the gasoline into the Nelson's
+tanks. Even this accession did not quite fill the latter.
+
+"Wish we could get to the motor car," Jimmie suggested.
+
+"Now," Ned said, "I want you two to kick up an awful rumpus here,
+directly. Shoot and do all the yelling possible. Let Collins loose
+and chase him! He deserves it! Then, when the fellows over there
+run up on the ledge to see what is doing, I'll swoop down in the
+aeroplane and pick up Lyman--that is, if he is willing to come with
+me. If he isn't, I can't get him, that's all."
+
+"Then, when we get up in the air, we take to our heels?"
+
+"Exactly. If you don't these fellows will make trouble for you.
+Hide, but keep making to the east. When I come back after you I'll
+come in from that way."
+
+"How long will it be?" asked the lad, who did not quite like the
+notion of being left there with Jackson.
+
+"I can't say," was the reply. "I may leave Lyman in the nearest
+town, or he may want to go to Asuncion. I may be back by daylight,
+and I may be gone two days. I hope to be back by daylight."
+
+"All right," Jimmie grunted. "We'll keep off to the east, and when
+you return you can pick us up before they know what's going on.
+Here's hoping you get Lyman!"
+
+"I'll get him!" Ned replied, shutting his teeth hard together.
+
+So, all arrangements made, Jimmie crept up on the ledge, about nine
+o'clock, and looked over into the twin valley.
+
+There was a campfire burning, and Lyman, or the man the boy took for
+the cattleman, sat close beside it. The others were walking about.
+Now and then an Indian stepped inside the circle of light cast by
+the fire, consulted with the others for a moment, and disappeared
+again.
+
+It was certain that the alleged officers were preparing to advance
+on the boys, bent on putting the Nelson out of commission for good.
+The planes had not been repaired any too quickly. When Jimmie
+reported Ned stepped into the machine.
+
+"When I get within sight of those in that valley," he said, "make
+all the noise you can. If you can cause them to think you're
+killing Collins, all the better. Make him yell! I'll go straight
+up and drop down by that fire before they get over their
+excitement."
+
+A few strong shoves, a dozen revolutions of the rubber-tired wheels,
+and the Nelson left the ground, as strong and capable as ever. The
+motors made little noise, and no signs of discovery came from the
+other side until the machine was high up. Then a few ineffectual
+shots were fired at her.
+
+Jimmie and Jackson began their part of the performance promptly by
+shooting and yelling. They loosened Collins, much to that
+gentleman's delight, and started him off in the dim light on a run.
+As Jackson took great delight in landing his bullets close to
+Collins' feet, the alleged salesman ran for dear life toward the
+ledge, screaming and calling for help at every jump.
+
+This was exactly what the others wanted, and in a short time they
+saw a huddle of dark figures on the ledge. In the excitement the
+firing on the Nelson had ceased.
+
+Jackson and Jimmie were not long in getting out of the valley after
+that. They whirled around the elevation between the two valleys,
+sometimes feeling their way in the darkness, climbed over a ledge,
+and made for the black entrance to the tunnel through which Jackson
+had entered.
+
+When they were at the mouth of the tunnel they turned and looked
+back. The Nelson was lifting from the valley where the fire had
+been seen, whirling up, up into the night sky. They could not
+determine from where they stood whether there were two or one on the
+big aeroplane. They had no means of knowing whether Ned had
+succeeded or failed.
+
+The two watched the dim bulk of the aeroplane as it winged over
+their heads. Now and then, after it was too late to do her any
+harm, a few vengeful shots were fired at her. The fact that Ned
+kept going convinced them that he had picked up Lyman and was on the
+way out with him.
+
+After the aeroplane had disappeared from sight Jackson and Jimmie
+hurried on through the dark tunnel, which, as has been said, was
+merely the dry channel of a stream which had cut its way out of the
+valley years before. Jimmie proposed that they remain there all
+night, but Jackson objected to this.
+
+Their pursuers knew that he knew of the tunnel, he explained, in
+support of his objection, as they were aware that he had entered the
+valley by that route, so they would naturally look there for them.
+
+This was convincing, of course, and the two hastened on their way,
+lighted by the little searchlight. For a long time there were no
+indications of pursuit, then a popping roar came beating down the
+passage.
+
+"That's the automobile!" Jimmie cried. "Sounds like an express
+train, eh?"
+
+"It certainly does," Jackson replied, "and it is up to us to get out
+of the way, somewhere. They won't take extra pains to catch us
+alive."
+
+
+
+
+CHAPTER XIV
+
+ARRESTED FOR SMUGGLING
+
+
+The Nelson swept out of the air like a bird and landed so close to
+the fire that Ned felt the warmth of it on his face. The wheels cut
+the earth at first, under the force of the quick descent, then
+stopped.
+
+The firelight shone on the white planes, bringing them out strongly
+against the darkness, and Ned knew that he could not remain there a
+minute without being discovered by the alleged officers of the
+little republic he was just then warring against. When he landed
+the men were out of sight around the ledge, but they of course saw
+the aeroplane and came running back.
+
+Lyman, or a man Ned believed to be the cattleman whose financial
+operations had stirred up an international row, stood moodily by the
+fire when the Nelson dropped down, almost on top of his head. He
+sprang away, rubbed his eyes as if trying to awake himself from a
+bad dream, and then stood stock still, watching.
+
+"Lyman?" Ned called.
+
+There was no reply, and Ned spoke the name again.
+
+"Yes, Lyman," the man by the fire answered, then. "What new wrinkle
+is this?" he added, stepping a little closer to the machine.
+
+"If you're Lyman," Ned replied, hastily, "you can't get in here any
+too quickly. Those fellows will be here directly, with Thomas Q.
+Collins in the lead, if my boys do their duty. There will be little
+chance for either of us then. Jump in!"
+
+"But I've never been on one of those things, and I'm afraid," Lyman
+said, with a shrug of the shoulders. "I'm afraid I'd fall out."
+
+A shot came from the ledge, and Ned reached for the button which
+would start the motors going.
+
+"You've only a minute to decide," he said. "I've come a long way to
+find you. If you reject this chance you won't get another."
+
+"Well," Lyman cried, stepping up to the seat, very shaky as to
+nerves and pale as death, "I may as well die from a fall as from a
+bullet or a knife. If Collins is coming back with the officers,
+I'll have to do something."
+
+The instant he was in his seat, Ned threw the leather straps about
+his legs and wrists and buckled them tight. Lyman shivered with
+fright.
+
+"I thought so!" he cried, mistaking Ned's motives. "This is only
+another trick!"
+
+The wheels bumped for an instant over the inequalities of the
+surface, the machine rocked lightly, then the planes lifted into the
+air, the propellers running like mad. A few ineffectual shots came
+from the men who were running down from the ledge. Ned saw Jimmie
+and Jackson chasing Collins out of the valley, heard their shots,
+and then, in a few moments, saw them at the mouth of the tunnel.
+
+In five minutes more the Nelson was out of all danger, purring
+through the darkness like a contented cat. Lyman sat moodily in his
+harness, saying not a word, but fully convinced that this was only
+another trick of his enemies. Directly the boy slowed the motors
+down so as to make conversation possible.
+
+"Well," he said, turning on one of the electric bulbs so as to see
+the face of his passenger, "what do you think of the Nelson? Peach,
+isn't she?"
+
+"Where are you taking me?" was the only reply to the question.
+
+"That is for you to say. We are not very far from Sicuani, Peru,
+and from there you can secure transportation back to Asuncion--if
+you think it safe to go there, under the circumstances. About a
+hundred miles to the north is Cuzco. You can go there and prepare
+for your visit to Asuncion if you care to. Then, over here in
+Bolivia, is Sucre. It might be well for you to go there. Anyway,
+it is up to you."
+
+"Who is doing this?" asked Lyman, suspiciously.
+
+"I can't see as that makes any difference to you," Ned replied.
+
+"I was in the hope," Lyman went on, "when you came down upon me so
+unexpectedly, that my friends had found me. You speak English like
+a New York man," he went on. "Perhaps you live over there?"
+
+"Yes," was the reply. "I live in New York, when I am home."
+
+"Nice little old rotten government we've got!" almost shouted Lyman.
+"The people at Washington let any crooked little republic do
+anything it has a mind to do to a citizen of the United States.
+They're too busy getting themselves into office and keeping in to
+pay any attention to their duties. England wouldn't stand for a
+minute the tricks that have been played on me, not by business
+rivals, but by the government of Paraguay! England protects her
+citizens, wherever they are!"
+
+"Well," Ned replied, with a laugh, "you may be right about England,
+but you are wrong about Uncle Sam. He looks after his own, too; if
+he didn't I wouldn't be here now. You wouldn't be on earth!"
+
+"Do you mean to say--"
+
+Lyman hesitated, and Ned went on and told him as much of the history
+of the expedition as he thought it necessary for the cattleman to
+know.
+
+"And now," he concluded, "Where do you want to go?"
+
+"I want you to go with me, wherever I go," was the reply. "And I
+think we'd better go straight to Asuncion."
+
+"Do you think that a safe plan?"
+
+"Oh, yes; they won't dare abduct me again."
+
+"Then," Ned added, "we may as well get on the way. Asuncion is
+somewhere about twelve hundred miles from here, and we've got to
+make it by daylight."
+
+"What's that?" asked Lyman, hardly believing he had heard aright.
+"You would better say in two days."
+
+"The Nelson can make it in eight hours," Ned replied, "if we don't
+drop into any holes in the air or adverse currents."
+
+"Holes in the air!" repeated Lyman.
+
+"Sure," answered Ned. "The atmosphere surrounding the earth is just
+like the water in the large reservoirs--there are deep places and
+shallow places, holes you can drop in, and currents like the Gulf
+Stream current, the Japanese current, which warms the northern
+states and British Columbia, and the Arctic Humboldt current, which
+sends a cold stream down the Pacific coast of South America. If we
+have no difficulties with these rivers of the air, and the wind does
+not come up too strong, we can make Asuncion by six o'clock in the
+morning. It is about ten now."
+
+"What sort of an airship have you here?" demanded Lyman, amazed at
+the thought of running at the rate of two hundred miles an hour or a
+hundred and fifty, at least.
+
+"She was built for speed and endurance," was the reply. "Now cover
+your face with this mask, unless you want to have your breath blown
+out of the back of your head, and we'll get under way."
+
+That was a night ride which neither of the participants ever forgot.
+The first part of the night was dark. Then a moon shone down from a
+cloudless sky, showing all the beauties of that magnificent country.
+
+The mountains, the forests, the headwaters of the rivers which help
+to make the Amazon, were under their feet. Now and then they swept
+over a point of light which denoted the presence of a small town.
+Occasionally the cry of frightened wild beasts--the vicious mountain
+lion, the savage tiger cat, the prowling puma--came up to their
+ears.
+
+After a short run to the southeast, Ned wheeled about and struck
+straight off to the east. The wind was growing stronger, and the
+Nelson was not making as good time as the boy desired.
+
+There was a fierce current about the top of Mt. Sorata, which is
+something over 21,000 feet in height, and again Ned swung off to the
+north. Dropping down, then, he swept into the valley of the Beni
+river, which joins the Madeira river, some distance beyond the
+Bolivian border.
+
+He knew that at the eastern rim of Bolivia there was a series of
+high mountain ranges which would protect him from the drifts blowing
+over from the Atlantic--Serre Geral, Serre Paxecis, Serre
+Aguapehy--and he reasoned that he could make better speed under the
+lee of these elevations. So he swept down the valley of the Beni
+until it joined with the Madeira, crossed a line of hills, and made
+for the Serre Geral range, something under a hundred miles away.
+
+As the Nelson cleared the valley, however, Lyman gave Ned a punch in
+the ribs with an elbow and nodded toward the ground. His wrists
+were fast in the harness so he could not use his hands. Ned looked
+down and instantly dropped the Nelson a few hundred feet.
+
+Some distance down the Madeira, in the center of the stream, were
+the lights of a boat which seemed to be anchored there. Ned swept
+closer and tried his best to make out the outlines of the craft, but
+he could not do it without descending close to the river, and this
+he did not care to do.
+
+"It looks like the Black Bear," he thought, as he shot up into the
+air again, "but of coarse it can't be. Those Boy Scouts are not
+fools enough to bring her up into this country."
+
+So he came to the protection of the mountains and proceeded south
+toward Asuncion at a speed which caused Lyman to gasp for breath.
+Of course he was ignorant of the fact that Frank, Jack, and Harry
+had started out, during his absence, to explore the headwaters of
+the Amazon, hoping to come upon the Nelson before returning.
+
+As for the lads on the Black Bear, they did not even know that the
+Nelson was so close to them that night. It was three nights later
+that they first saw the aeroplane drifting above them. Asuncion
+does not at all compare in beauty or in thrift with the other
+capital cities of South America. The government of the republic is
+so unstable that business men are loath to make heavy investments
+there.
+
+For one thing the town is poorly lighted, and when Ned came, in view
+of the place at five O'clock the few street lamps were already out.
+People were abroad at that early hour, however, and small crowds
+soon gathered on the street corners to watch the great airship
+approach.
+
+What Ned could not see was the intense excitement around the
+government offices. In ten minutes from the time the airship showed
+above the city, messengers were out in the streets and officials of
+the lower rank were headed for their offices. In a few minutes this
+alarm was communicated to police headquarters and to the military
+station where the governor's guard was stationed.
+
+If the boy had been able to understand the situation below, if he
+had known that Asuncion had been communicated with from Lima and
+also from Sicuani, he would have given the city a wide berth. He
+saw the gathering of crowds below, of course, but naturally
+attributed this to curiosity. He had no doubt that the Nelson was
+the first airship ever seen at Asuncion.
+
+"Where are you going to take me?" asked Lyman, as the machine slowed
+down and he found himself able to speak.
+
+"To the American consul," was the reply.
+
+Lyman sighed and shook his head.
+
+"I'm afraid he will take little interest in me," he said.
+
+"Doubtless," Ned replied, "he has received instructions from
+Washington. Anyway, I fail to see how they can molest you now, even
+if they have the inclination to do so. You just go about your
+business as usual, and leave this abduction matter to the future.
+You can gain nothing now by stirring that up. Report to the consul
+and go on about your business as if nothing had happened."
+
+"That is the only thing there is to do," Lyman responded, with a
+sigh. "Still, I'm suspicious of those chaps. They'll have some
+trick ready."
+
+Before long Ned found a level spot not far from the capitol building
+where he could, drop the Nelson. When he headed for that locality
+he was followed through the streets below by a shouting, howling
+mob.
+
+"I can't understand this," he thought, and Lyman was still more
+suspicious.
+
+At last the Nelson was brought to the surface of the earth and Ned
+and Lyman stepped out, very willing to stretch their legs after such
+a long ride. They had been in the air about twice the time set for
+endurance by noted aviators.
+
+They did not get much of a chance to stretch their legs, however,
+for they bumped into a squad of soldiers on stepping out of their
+seats.
+
+"You are under arrest!" a gaily-dressed officer said, flashing his
+sword out of its scabbard.
+
+"What for?" demanded Ned, speaking in Spanish.
+
+"Smuggling!" was the reply.
+
+Ned laughed heartily. Arrested for smuggling!
+
+"Search us, and search the machine, then," he replied, "and let us
+go on about our business. We have no time to lose."
+
+"In time! In time!" was the drawling reply. "Such things are not
+done so quickly here! In three-four days--in a week--in three, four
+weeks, perhaps. In the meantime you go to the jail."
+
+Ned thought of the swiftly-slipping days, of the peril Jimmie and
+Jackson were in, of Leroy in prison at Lima, and was about ready to
+fight. The officer refused to take him to the president, or to the
+American consul. In a quarter of an hour he was in a cell, alone,
+wondering what had been done with Lyman, and also wondering what
+would become of the Nelson.
+
+He knew that the charge of smuggling, of bringing goods into the
+republic by means of an airship, would be held against him as long
+as it pleased his accusers to keep him in prison. That would be
+until the concession expired and, possibly, until the Nelson lay a
+total wreck in the streets.
+
+He saw no one who could give him any information as to what was
+going on in the outside until the morning of the 21st, after he had
+been incarcerated forty-eight hours. Then a turnkey unlocked his
+door and motioned him out.
+
+"For trial?" Ned asked, hopefully.
+
+"It is the wish of the president," was the reply.
+
+"But what, why, when--"
+
+"You have yet to see," was the impertinent reply. "You have yet to
+see if you can do these things to our countree!"
+
+And so, mystified and, if the truth must be told, not a little
+discouraged, Ned was led through the prison corridors, his mind
+filled wit thoughts of Leroy, Jimmie, the Nelson, an, strangely
+enough, the Black Bear!
+
+
+
+
+
+CHAPTER XV
+
+THE WARNING FROM THE SKY
+
+
+There was a shock when the prow of the Black Bear struck a canoe
+which lay full in its path. The momentum was retarded for only a
+second. Then the motor boat was beyond the line of war canoes with
+their screaming, gesticulating occupants.
+
+Looking out of the rear ventilator, Frank saw a smashed canoe
+running down with the current, with a dozen or more natives clinging
+to it. But there was still a large number of canoes up the river,
+and the Black Bear was struck more than once by forceless bullets
+and poisoned arrows as she sped past them.
+
+Armed with modern rifles, the Indians would have made short work of
+the occupants of the Black Bear, but the muskets they used were old
+and mostly out of condition. The arrows were far more deadly,
+although they stood less chance of penetrating the tough panels.
+
+"Now," Harry said, as they passed a racing fleet of Indian boats,
+"we can open up a little and get a breath of fresh air! I'm just
+about suffocated!"
+
+"Not just yet," Jack, who was at the front, said, "for there's a
+mess of the black scamps just ahead. They are on the bank, both
+banks, and seem to be waiting for something to happen. I wonder
+what it can be?"
+
+"Some trap, I suppose," Harry gritted. "Well, all we can do is to
+ran on through them, if they come out in boats, and get out of their
+reach. We ought to be able to be out of this blasted country in a
+couple of hours."
+
+"That's all right," Jack replied, "but you just listen a moment."
+
+But the racing motors shut out all individual sounds, and Harry shut
+them down for a minute. Seeing this, Jack dropped an anchor at the
+prow, and the boat lay pulling at the cable in the current.
+
+"What did you do that for?" asked Frank, addressing both boys from
+the stem.
+
+"Listen!" commanded Jack.
+
+"Look!" ordered Harry.
+
+What Frank heard was the heavy, continuous roar of a waterfall.
+What he saw, as he crowded up under the plate glass panel in the
+top, were the lights of an airship!
+
+"I tell you," Harry cried, excitedly, "that that's the Nelson. You
+can't fool me about that."
+
+"Why doesn't she come down, then?" demanded Jack.
+
+"Because she doesn't know that this is the Black Bear. That is an
+easy one! If she did she'd be here in a second."
+
+The boys studied the lights a moment and then turned their attention
+to the Indians, who were now making a great clamor. In a short time
+it was easy to see what they were up to.
+
+Above roared the falls and the rapids. At this point in the Beni
+river there is a swift drop from the mountain plateau above. It
+will be remembered that the Beni reaches away up into the Illimani
+mountains, with its springs not far distant from the summit of the
+Andes.
+
+Where the boys were the Paredon and the Paderneira, falls and the
+Araras and the Misericordia rapids made the navigation of the river,
+even in the protected Black Bear, impossible for many miles. The
+Indians seemed to understand this, for they had gathered at the foot
+of the falls, possibly expecting to see the craft attempt the
+ascent.
+
+Jack watched them from the prow for a time and then asked:
+
+"What's that they are throwing into the river?"
+
+"Logs!" replied Harry, looking out over Jack's shoulder, "and
+brush!"
+
+"Well, of all the--"
+
+The sentence was not finished. Frank, at the stern, gave a yell and
+fired out of the loophole. "Come here!" he shouted, then, "if you
+want to see what the devils are doing. This takes the cake!"
+
+A glance showed the others what the plot against them was. Harry
+went to his locker for his revolver and Jack drew his from a pocket.
+
+"I guess it is a fight now!" Frank said. "You see what they are
+doing?"
+
+"Of course. Anybody can see that."
+
+Jack reached out of the opening and fired a perfect volley down
+stream. Frank crowded against him to look out.
+
+"Never touched them!" he cried.
+
+"No," Jack went on, "they're forming a bridge with their canoes and
+running logs and brush down against it. They've got an obstruction
+already that the Black Bear never can get through."
+
+"What's the matter with dynamite?" asked Harry.
+
+"Oh, we can use dynamite as long as we have it," was the reply, "but
+there will be Indians on guard there long after we are out of the
+stuff."
+
+"I guess that's right!" with a sober drawing of the lips.
+
+"I'll tell you what we've got to do," Harry said, presently. "We've
+got to put on full power and try to run up the rapids."
+
+"Why, there is noise enough for a ten-foot fall," Frank replied.
+
+"We've got to risk it," Jack went on.
+
+"Now, you just wait," Frank cut in. "I don't think you've got this
+thing sized up right at all. Harry," he continued, "who does this
+boat belong to?"
+
+"To the Black Bear Patrol," was the reply. "You know that well
+enough."
+
+"Then we can do what we please with it, so long as we make it right
+with the other members of the Patrol?"
+
+"Why, of course."
+
+Jack looked at his chums with a grin.
+
+"What are you figuring on?" he asked. "One would think you were
+planning to blow the Black Bear into smithereens."
+
+"That's about it," Frank replied.
+
+"And go to kingdom come with her?" laughed Jack. "Not any of that
+for me. I'm headed, eventually, for little old N.Y."
+
+"I'm tired of fooling with these cannibals," Frank explained. "We
+haven't molested them, and yet they are after our scalps. They'll
+get them, too, if something isn't done--and done right away, at
+that."
+
+"I'm with you!" Jack exclaimed. "I'm willing to try anything once.
+Only let me in on the secret!" he added, chuckling.
+
+ "You had it right," Frank said. "What I propose is to blow the
+Black Bear into smithereens, and about a thousand of those
+bloodthirsty natives with it. The world will be all the better for
+their being out of it. They are worse than the savage beasts in the
+forests."
+
+"But what is to become of us?" asked Harry.
+
+Frank pointed to the Wolf, tugging at the cable which held her nose
+to the stem of the Black Bear.
+
+"We'll be safe in there when the explosion takes place," he said.
+
+Jack clapped the speaker on the shoulder.
+
+"You're all right!" he cried.
+
+Harry looked mystified for a moment, and then said, speaking loudly
+in order that his voice might be heard above the shouts of the
+savages and the beating of arrows against the panels of the boat:
+
+"It looks as if we'd have to do it. I hate to leave the Black Bear
+in such a mess away off here in South America, but I don't see how
+we are to get her out. The Wolf will carry us all right, I
+suppose?" he said, tentatively.
+
+"Sure thing!" Frank replied. "I've been thinking it all out. We'll
+do it this way: When we get ready we'll put on full speed ahead on
+the motors, with the prow turned against that obstruction below.
+Then we'll hop into the Wolf and shut everything down tight. The
+Black Bear will weaken the jam below, and the sharp nose of the Wolf
+will poke through the rest of the logs and canoes. And there you
+are!"
+
+"Free of the natives, and bobbing down the, river in safety!" cried
+Jack. "That looks good to me!"
+
+"But about the dynamite?" asked Harry.
+
+"Well," Frank replied, "we've got to use the Black Bear for a
+battering ram anyway, and she'll be all smashed up, so we may as
+well go the whole hog with her. We'll put a lot of dynamite down
+under the motors and fix a cap so it will blow up when the
+concussion comes. By that time the natives will be swarming around
+her, and they'll get what's coming to them."
+
+"And where will we be when the explosion is rocking this half of the
+world?" demanded Harry. "Up in the air?"
+
+"We'll be a cuddled up in the Wolf, between the lockers, with plenty
+of grub and ammunition, sailing down the river in a bullet-proof
+vessel. This move will burst up our meeting with the Nelson, of
+course, but there is no other way. They'll get us if we remain
+here."
+
+While this talk had been going on, the cannibals had drawn nearer to
+the Black Bear, pressing forward from both banks in canoes and
+pounding at the panels with their arrows. It seemed only a question
+of time when they would board the craft and force the panels. Their
+shouts of victory were shrill and exasperating.
+
+"You see how it is," Frank said, "the Black Bear can never be pushed
+up over the falls, and we can never get her past the obstructions
+below, even by the use of dynamite. If we could blow the those logs
+out of the way, the Indians would board us instantly. We could give
+them only a charge or two of dynamite and a few shots before they
+would be inside. Now' we can drift down the river in the Wolf
+without fear of entertaining man-eaters on board. They may get on
+top of the boat, but they can never get inside."
+
+"And so we'll have to give up our trip!" wailed Harry. "We'll have
+to drift down stream in that hot hole and take a steamer at the
+nearest river town!"
+
+"It strikes me," Frank observed, "that it is a mighty good thing
+we've got that hot hole to drift down stream in. If the Black Bear
+had only been constructed on the principle of the Wolf, we'd be in a
+position to give these heathens the laugh. Well, let us pull the
+Wolf up and throw out stuff enough to give us room. Then we'll get
+out the dynamite."
+
+The boys drew the Wolf up by the cable as Frank tried to elude the
+watchful eyes of the savages long enough to open the hatch on top
+and climb inside, but a dozen arrows whizzed by his head when he
+looked out.
+
+"Can't do it!" he said.
+
+"Never in the world!" Jack assented.
+
+"Another good scheme gone wrong!" Harry ejaculated. "What next?"
+
+"Dynamite," almost shouted Jack. "We'll give them dynamite as long
+as it lasts, and then ram the logs below."
+
+"We may kill, a couple of hundred," Frank said, "but it seems to me
+that there will be about ten thousand left."
+
+The boys were indeed in a tight box. With their automatics and
+their dynamite they might keep the natives at bay for a time, but in
+the end they would be obliged to surrender or starve to death.
+
+"Well," Jack said, grimly, "let's get out the dynamite. I want to
+see some of these devils blown up!"
+
+Just then an arrow struck the plate glass panel at the top of the
+Black Bear's deck covering and Jack looked up. He gazed a moment in
+wonder and then let out a shout that rose above the yelling of the
+savages and the pounding of arrows against the panels of the Black
+Bear.
+
+"Glory be!" he shouted.
+
+Frank and Harry crowded to his side and looked up.
+
+"It is the Nelson!" Harry exclaimed.
+
+"You bet it is!" Frank admitted.
+
+"Good old Ned!" Jack roared.
+
+The aeroplane was only a few yards above the Black Bear. Already
+the natives were slinking away in their canoes. Those on the banks
+were slowly withdrawing into the shelter of the forests.
+
+"They're running away!" Jack cried. "Now we'll have some fun with
+good old Ned Nestor!"
+
+For a moment it looked as if the statement was correct; as if the
+natives, alarmed at the sight of the aeroplane would disappear from
+sight without a fight. But this supposition was soon disproved.
+
+As the Nelson came nearer, a dozen bullets from the forests struck
+her planes. The boys, in the boat raised the panel and shouted to
+the aviator to look out for poisoned arrows.
+
+Then the aeroplane shot up again. They could see that there was
+only one person on the machine, and that he was busy arranging
+something which looked like a stick of dynamite which he held in his
+hands.
+
+In a moment something grim and sinister whirled and hissed through
+the air, and then there came a terrific explosion in the forest to
+the right. Trees were leveled, and a great hole showed in the bank.
+In an instant, following close on the roar of the dynamite, there
+came a chorus of cries from savage throats-cries of fear, of terror,
+of rage--and then silence.
+
+For a moment it seemed as if the forests held no forms of animal
+life, then the sharp call of the tiger-cat, the wail of the puma,
+the chattering of the monkeys, came to the ears of the listening
+boys.
+
+"I guess this coming act will consist of a feed for the wild
+beasts!" Jack said.
+
+For a long time there was no sound of savage life in the forests,
+save that from the throats of beasts of prey, scenting blood and
+slowly drawing closer to the river's banks. The boys on the Black
+Bear looked into each other's faces and wondered.
+
+"They didn't act that way when we exploded dynamite!" Jack said.
+
+"No. They came right back at us!" Frank replied.
+
+"I take it that they think there's something supernatural in this
+dropping of dynamite from the sky," Harry observed. "Anyway, they
+seem to have taken themselves off, and we'll open up and signal to
+the Nelson! Say, won't it be fine to see good old Ned Nestor again?
+I wonder how he knew we were here?"
+
+"And I wonder where Jimmie and Leroy are?" Harry reflected. "There
+is only one person on the machine, and that must be Ned."
+
+Jack was about to throw open the top panels when he caught sight of
+the aeroplane again, nearer to the water than before.
+
+"What's Ned doing?" he asked, pointing upward.
+
+"Talking!" exclaimed Frank.
+
+"Wigwagging!" Harry broke out. "Now, let us see what he says."
+
+Slowly to the right and left, up and down, an electric bulb flashed
+in the sky. Harry counted.
+
+"That's C;" he said, "and that's 'a,' and that's 'u,' and that's
+'t,' and now 'i,' and 'o,' and 'n.' 'Caution!' That means that
+we've got to stand pat for a time yet."
+
+"It also means," Jack said, "that we've made no mistake about that
+being the Nelson, with a Boy Scout on board. Those wigwag signals
+show the supposition to be true."
+
+"Well," Harry puzzled, "he wouldn't be sending us a warning from the
+sky if there wasn't some danger we were not aware of. There is
+something going on that we are not wise to."
+
+There was a short silence on board and then Frank remarked:
+
+"We must be nearer the falls than we thought, for the water seems to
+be a ripple about us. Rear it! I'm going to look out and see it
+looks like."
+
+In a moment he was jamming the panel shut and springing the slides
+over the loopholes and the ventilators.
+
+Jack sprang to the prow, not knowing what danger threatened, but
+obeying the sudden gestures of his chum to close every opening.
+Before he sprung the steel panel over the ventilator he glanced
+out on the river.
+
+"Great heavens!" he cried. "Get your guns, boys!"
+
+The whole surface of the stream, as far as the boy's eyes reached,
+seemed covered with savage heads, floating, drifting, down upon the
+Black Bear.
+
+
+
+
+CHAPTER XVI
+
+RED FIRE FROM THE SKY
+
+
+Under the light of the moon the rushing river seemed full of
+leering, cruel eyes. The bodies of the swimming savages were not
+visible--only the upturned faces and the threatening eyes, with now
+and then a hand or the point of a glistening shoulder. There
+appeared to be thousands of the cannibals; their mass reaching from
+shore to shore.
+
+Then, while the boys looked, expecting every instant to hear the
+sound of feet outside the panels, a rocket shot out from the Nelson
+and a score of parti-colored balls curved and hissed toward the
+earth.
+
+"Gee!" Jack cried. "He's giving them a fourth-of-July celebration!"
+
+"Hope it scares them off," said Harry.
+
+Looking through the heavy glass panel at the top, they saw a rain of
+red fire drop down on the swirling river. For a moment the whole
+upper air, then river and forest, was painted a bloody red by the
+burning powder.
+
+Cries came from the river, and the mass of floating heads parted and
+swung swiftly toward the shores; then silence. The aeroplane
+circled about cautiously and then dropped down lower. Jack opened
+the panel.
+
+"Hello the boat!" cried a voice from the aviator's seat.
+
+"Hello, Ned!" all three boys called back.
+
+"How do you know it's Ned?" was asked.
+
+"We saw that beautiful face of yours in the red fire," replied Jack.
+"How are we going to get out of here? They've blockaded the river
+below, and the falls are above."
+
+"I presume I have dynamite enough to blow up that improvised dam,"
+replied Ned. "Why didn't you do it?"
+
+Before Jack could explain the situation, the Nelson drifted past,
+and he knew that his voice would not carry to her.
+
+"I'm going to open up now," Harry said, as the Nelson drifted out of
+range of the glass pane. "I'm pretty near choked in here."
+
+"Nice time we would have had in the Wolf," laughed Jack.
+
+"Anyway," urged Harry, "we should have been in her in a minute if
+the Nelson hadn't shown up. Say, won't they give us the laugh in
+New York? Came away off out here alone, and then had to be rescued
+by Ned!"
+
+ Very cautiously the panels giving on the stern were opened. There
+were no savages in view. The banks of the stream seemed as quiet
+and harmless as a thicket in Central Park.
+
+"I guess the rocket and the red fire got them!" grinned Frank.
+
+"Yes, but they won't stay scared forever!" Harry put in. "We'd
+better be getting out of this before they come back to their
+senses."
+
+"They never had any senses!" claimed Jack.
+
+Looking out from the interior, now guarded only by the panels at the
+front and sides, the boys saw Ned drop half a dozen sticks of
+dynamite on the logs and brush which had been floated down on top of
+a number of canoes. In some places the logs had pushed up until
+they were high above the surface of the water.
+
+The pressure of the current was continually making the obstruction
+more compact. The canoes seemed to have been bound firmly together
+and stretched from shore to shore. At least the moorings were
+strong, for the logs were heavy and the current pulled heavily at
+them.
+
+The explosions made great havoc with the barricade, and presently
+the line was broken and the whole mass swung shoreward or drifted
+down stream.
+
+Then Ned called out:
+
+"Now drop down stream and I will join you."
+
+"Better look out where you land!" Harry called back.
+
+"I hope I won't get into any such scrape as you did," Ned replied.
+
+"Oh, you're not out of it yet!" laughed Frank. "These woods are
+full of man-eaters. Look out where you go, and we'll find a place
+for you to come down."
+
+The anchor of the Black Bear was lifted and the power turned on. In
+a minute she was going down stream at a thirty-mile gait.
+
+Directly they passed the wrecked barricade, rolling and tumbling in
+the waters, the canoes either broken or half full of water. The
+Nelson still led the way down the stream.
+
+"I guess he's never going to stop."
+
+"Wonder if he's going back to New York?"
+
+"Perhaps he's lost control!"
+
+The boys looked and wondered as the aeroplane drifted on to the
+north and cast. They were miles from the scene of the battle now,
+but the airship went on.
+
+Presently they saw the purpose of the aviator in making this long
+run. A little nest of houses flashed out on the river bank, with
+here and there a light showing, and here the onward course of the
+Nelson became a circling descent.
+
+In the east there was a faint line of dawn in the sky when the Black
+Bear was pushed up to a primitive wharf. The aeroplane was still
+circling in the air.
+
+"He wants us to pick out a spot for him to land on," Jack said.
+"There's one over by that hill," he added.
+
+When Ned saw the three boys gather at the spot indicated and motion
+to him to come down he lost no time in doing so. When he stepped
+out of his seat all three lads were upon him. One would have
+thought they were determined to tear him in pieces the way they
+seized his hands, his legs, and pulled at his neck.
+
+"You old fraud!"
+
+"How did you know?"
+
+"You're a nice old chaperon!"
+
+For a moment Ned could not say a word, then he pushed the boys away
+and sat down on the ground.
+
+"You're a nice bunch!" he said.
+
+"Sure!" said Jack.
+
+"The people back there thought so much of us that they wanted us to
+remain to dinner!" grinned Harry.
+
+"There ain't no better people!" Frank insisted.
+
+"How did you happen to get out here?" demanded Ned. "Why, you
+fellows ought to have a chaperon. Those cannibals would have had a
+good dinner today if the Nelson hadn't come that way."
+
+"Now, don't crow over us!" pleaded Frank. "We know all about it.
+You've gotten us out of many a scrape, but this is the large event.
+We take off our hats to you. Now, where's Jimmie and Leroy?"
+
+"I don't know," answered Ned, gravely.
+
+"I guess you are the one who needs a--"
+
+"I guess you are right," Ned replied. "I've been up against the
+pricks good and plenty since I left you. If I get to New York
+alive, I'm going to stay there for good."
+
+"Where did you leave Leroy?" asked Frank.
+
+"In jail!"
+
+"Wow!" cried all three boys.
+
+"And Jimmie? I don't see how you happened to lose him."
+
+"Jimmie is lost in the Peruvian mountains," Ned said.
+
+"Well, why don't we go and get him?" asked Harry.
+
+"Yes," laughed Frank. "We might ride in the Black Bear over the
+storm-tossed summits of the Andes!"
+
+"At least," Ned said, "you boys can help me a lot. I have my hands
+full. We can all ride the Nelson, I take it. She was built to
+carry three average-weight men, you know, and I think she ought to
+manage three boys and one man!"
+
+"Oh, you man!" laughed Jack, poking Ned in the side. "You man who
+has to come to the three boys for help!"
+
+"Tell us about it," Frank said.
+
+"The quicker we start in on the search for Jimmie the quicker he
+will be found," Harry insisted.
+
+It was not much of a town where the Nelson had landed. There were a
+few native houses and a great warehouse, at one end of which was a
+small office. Such river products as came from up stream were
+packed there to await transportation down to the Amazon.
+
+By the time the sun was up a score or more natives and a couple of
+British traders were gathered about the aeroplane and the Black
+Bear. One of the traders, Mr. Hamlin, invited the boys to his home
+for breakfast, and left some of his employees on guard at the Nelson
+and the Black Bear.
+
+During the breakfast Ned recounted his adventures, to which the host
+listened with the closest attention. Frank then told of the cruise
+of the Black Bear, adding that they had hoped to reach the very last
+yard of water flowing down the Andes slope to the east.
+
+"It is wonderful what American Boy Scouts will accomplish!" Mr.
+Hamlin said, when the tales had been told. "A few years ago no boy
+of your age would have undertaken such a duty as sent you to
+Paraguay," he added, addressing Ned, "and no boys would have dared
+to navigate the Beni river," he continued, smiling at the three
+bright faces on the other side of the table.
+
+"The Boy Scout training makes for courage and resourcefulness," Ned
+said. "We have not been caught in many traps. In fact, I think we
+are now up against the very worst situation we have ever
+encountered."
+
+"But you haven't yet told us how you got out of jail at Asuncion,
+only that you got in on a smuggling charge and were released. Who
+brought about the release?"
+
+"The president of the Republic," was the reply. "He learned of the
+matter and ordered me brought before him. Well, I had been
+searched, and the Nelson had been searched, and nothing found, so I
+was let go. The president also ordered the Nelson returned to me.
+It had been appropriated by an official who had declared it
+forfeited. Not a bad chap that president, still, I think he saw
+Uncle Sam in the background!"
+
+"And about this man Lyman?"
+
+"I was told that he had gone back to his concession. I went out
+there in the airship, but failed to find him. After we find Jimmie
+and get Leroy out of the jail at Lima I'm going to find Lyman once
+more."
+
+"This," Jack said, "is the 23d of August. Now, we saw you last
+night, the 22d, and the night before, the 21st. Why didn't you come
+down then?"
+
+"Because I was not certain that it was the Black Bear, and because I
+wanted to investigate the place where I last saw Jimmie and the man
+Jackson. I was over the boat longer ago than the night of the 21st,
+but you did not know it, I guess."
+
+"Well, you came at the right time, when you did come," Jack said.
+"I only wish you hadn't found us in such a pickle!"
+
+"It doesn't seem to me," Mr. Hamlin suggested, "that the Nelson
+ought to carry four. You may have to go pretty fast. Now, one of
+you can remain with me, in welcome, and look after the Black Bear.
+I have plenty of gasoline, and we can amuse ourselves with trips on
+the river. Later, you can come back after the boat."
+
+"I think I'd better stay," Harry Stevens said. "I'm not stuck on
+long rides in the air. Besides, you can do just as well without me.
+How far is it to the place where you left Jimmie and this man
+Jackson?"
+
+Ned took out his pocket map and bent over it.
+
+"Here we are," he said, presently, "in the valley of the Madeira,
+with a range of mountains on each side. Below are the rapids and
+the falls. You must have had a sweet time traveling up from Fort
+San Antonio. You passed about three hundred miles of swift rapids
+and falls. How many times did you have to take the Black Bear to
+pieces?"
+
+"Not once there," was the reply. "We managed to steam up. But,
+say, we had a lovely time getting up over one waterfall!"
+
+"Well," Ned went on, "here we are at the big bend of the upper
+Madeira. We are not far from a thousand miles from the place where
+I found Lyman. We can get there by nightfall."
+
+"Not for me," Jack said, with a shrug of the shoulders. "We should
+have to ride continuously to make it in that time, and I don't like
+to remain in the air that long. We ought to have five rests of an
+hour each, and get there in the morning."
+
+"Yes," Ned replied, "I'm getting tired of long rides myself. We'll
+go slower."
+
+After breakfast the boys went to the Black Bear and looked her over.
+The propeller which had been broken could easily be repaired, they
+found, so they left that matter to Harry, replenished the tanks of
+the Nelson with gasoline, and prepared for the long journey back to
+the mountains of Peru.
+
+"When are you coming back?" asked Harry, as the three mounted the
+machine.
+
+"In three days," replied Ned. "And we'll bring Jimmie with us."
+
+"If they haven't fed him to the mountain lions before now!" Harry
+said, with a strange premonition of evil in his heart.
+
+And the Nelson was up and away, and Harry set to work cleaning up
+the motor boat, hoping to forget in toil how lonely and apprehensive
+he was.
+
+
+
+
+CHAPTER XVII
+
+USING BOY SCOUTS FOR BAIT!
+
+
+Alarmed by the swift approach of the motor car in the tunnel, Jimmie
+and Jackson took to their heels and made swift progress toward the
+east entrance, throwing the searchlight about and keeping their eyes
+out for some hiding place as they ran.
+
+Before long it became evident that they could not long maintain the
+pace they had taken. The motor car was gaining on them rapidly, as
+they knew by the steady approach of the clamor which the engines
+were making.
+
+"Gee!" cried Jimmie, at last. "No use! I've got to drop in
+somewhere!"
+
+Jackson was as ready to stop running as was Jimmie, so they drew up
+against the wall and Jimmie shut off the light from his electric
+candle.
+
+"Do you think they saw that light?" asked Jimmie, pushing close to
+the rock wall. "I hope not."
+
+"Probably not, as there was always an angle between us," was the
+whispered reply, "but their light is coming around that angle now.
+Stand close!"
+
+It was of little use to stand close.
+
+Under the great lamps every crack and crevice of the tunnel walls
+was in plain sight to the occupants of the car. The two fugitives
+might as well have attempted concealment under the limelight in the
+center of the stage of a Broadway theatre!
+
+Jimmie's hand was on his automatic as the car halted in front of
+him. Jackson saw what was in the boy's mind and laid a hand on his
+arm.
+
+"None of that!" he said.
+
+"Well, I'm not goin' to be--"
+
+Jackson forced the revolver out of the boy's hand as he brought it
+out of his pocket.
+
+"They've got us," he whispered, "and will be only too glad of an
+excuse to shoot us down in cold blood."
+
+"Well!"
+
+This from Thomas Q. Collins, who sat in the front seat, looking at
+the two as if he could bite them in pieces!
+
+Jimmie looked sullenly toward his automatic, in Jackson's hand, and
+said not a word. Jackson stepped forward.
+
+"You've got us!" he said.
+
+"You bet we have!" gloated Collins. "Where did that Nestor boy go
+with the man he picked up by the fire?"
+
+"Did he get him?" asked Jimmie.
+
+"Yes, he got him, worse luck!" was the reply. "Where did he go with
+him?"
+
+"Don't know," replied Jimmie.
+
+"I'll find a way to make you know!" gritted Collins. "Do you
+fellows know what it is to be hungry?"
+
+"Honest," Jackson cut in, "we don't know where Nestor went with
+Lyman. When he left us, he was not certain that he could get him.
+Thought Lyman might not want to go away with a stranger on such
+short notice."
+
+"Oh, what's the use?" demanded one of the others. "The fellow has
+gone back to Asuncion. That's easy to figure out. Who set you boys
+at work on this case?" he added, in a moment, at a whisper from his
+seat-mate.
+
+"Ned set me at work," Jimmie answered.
+
+"Yes, but who set him at work?"
+
+"I'll tell you," Jackson said, with a smile of satisfaction on his
+face, "the United States government set Ned at work. You'd better
+watch out how you butt up against the Secret Service men."
+
+"That's just what I told you!" sneered Collins. "You wouldn't
+believe me. Now what do you think?"
+
+The speaker left his seat in the machine and walked over to where
+Jackson was standing, the revolver still in his hand.
+
+"Give me that gun!" he demanded.
+
+Jackson passed it over without a word of protest.
+
+"Now your own gun," Collins demanded, extending his hand.
+
+"I have no gun," was the reply. "You know that very well."
+
+"I thought you might have stolen one since leaving the cow country,"
+snarled the other. "There is no knowing what kind of property you
+light-fingered gentlemen will acquire."
+
+"You're a liar, Collins," Jackson said, coolly. "You know I never
+ran off the cattle which were missed. I believe you stole them!"
+
+Collins advanced angrily toward the speaker, but one of his company
+drew him back.
+
+"Cut it out!" he said. "There will be plenty of time later on."
+
+"What are you going to do with us?" asked Jimmie.
+
+"You'll see!" Collins replied. "I wonder how you would like a game
+of chase-the-bullet? Similar to the one you gave me not long ago?"
+
+"Like it fine," Jimmie grinned, "if it didn't do me no more harm
+than it did you. Never touched you!"
+
+"It may be different in your case," Collins threatened.
+
+After consulting together in whispers for some moments, the men
+loaded Jimmie and Jackson into the crowded motor car and put on the
+reverse movement. In half an hour, the progress being slow, they
+came to the valley where the campfire was still burning. Here they
+all alighted.
+
+Half a dozen Peruvian Indians of vicious appearance now came
+forward, and Collins gave them instructions in an undertone, after
+which the two captives were led away to the cavern in which Lyman
+had been sheltered up to the time of the arrival of the Nelson. One
+of the Indians remained outside while the others hastened away.
+
+"Well," Jimmie said, as he looked gloomily at the discouraged
+Jackson, "what do you think of this? I'd like to push the face of
+that Collins person in so it would mix with the back curtain."
+
+"We're in for it!" moaned Jackson.
+
+"Aw, what can they do to us?" demanded the little fellow.
+
+"They can keep us here until we die of starvation," replied Jackson.
+"I've had a turn with starvation, and know what it's like."
+
+Jimmie reached under his coat and brought out a can of beans.
+
+"Here," he said, "get busy on this."
+
+"They took mine away when they searched me for a gun," said Jackson.
+
+"Buck up!" advised Jimmie. "We've got to figure out some way to
+give them the slip. What?"
+
+"Yes, I suppose so!"
+
+Jackson had counted on getting back to civilization without further
+difficulties, on the arrival of the Nelson, and now he was
+completely discouraged. Jimmie sat on the floor of the cavern and
+eyed him quizzically.
+
+"Ned will come back after us," the little one said, presently. "You
+put your bloomin' trust in Ned, an' you'll come a four-time winner
+out of the box. I know. I've been out with him before."
+
+"But how will he ever find us here?" asked Jackson.
+
+"How did he ever find Lyman?" demanded the boy. "You hush your
+kickin' an' leave it all to Ned. Guess he knows enough to get us
+out of this sink of iniquity! That boy eats 'em alive!"
+
+"I can't see why they should keep us here," Jackson remarked,
+presently, prying off the top of the can of beans with his pocket
+knife. "Why don't they go back to Asuncion and look after that
+cattle concession?"
+
+"Because they've got some one there to look out for it for them,"
+replied the boy. "They're waitin' here for Ned to come back an' get
+us, if anybody should ask you," he went on, his cheerful smile not
+at all matching the serious import of his words. "This Collins
+person has cards up his sleeve, an' he wants to get hold of Ned.
+He's set his trap with us for bait."
+
+"You're a cheerful little cuss!" grinned Jackson, beginning to see
+the dangerous side of the situation. "And what are we going to do
+when Ned comes back? Let them soak him?"
+
+"Not so you could notice it," was the reply. "When Ned comes back
+we'll be out at the other end of that tunnel, an' he'll swoop do in
+in the Nelson an' pick us up, an' we'll be back in little old N. Y.
+before you can say scat."
+
+"But how can we--"
+
+The entrance to the cavern was darkened for a moment and then the
+flashily-dressed form of Collins made its appearance.
+
+"What's that about getting back to little old N. Y.?" he asked.
+"When do you start for Manhattan Island?"
+
+"You heard, then?" asked Jackson.
+
+"Of course."
+
+"Well?"
+
+"Well, we'll see that you don't get away until this Ned comes back
+after you. We need him in our business."
+
+"He'll land Lyman at Asuncion before you see him again," Jimmie
+said.
+
+"Not a doubt of it," was the sullen reply, "but don't you ever think
+we haven't got people there who will look out for our interests.
+Lyman won't be at liberty long, and your Ned will come back here to
+get what's coming to him."
+
+"Is that so?" exclaimed the boy, putting on a bold front, but
+inwardly fearful that the situation was a tragic one.
+
+Leaving the captives with this cheering (?) information, Collins
+went back to his companions, leaving the Indian still on guard. For
+a time the Indian stood stolidly in front of the cave, then, looking
+carefully about to see that he was not observed by his employers, he
+faced the opening and uttered one English word:
+
+"Prepared."
+
+Jackson opened his eyes in amazement, but Jimmie saw an extended
+hand and sprang forward. The Indian's right hand was extended
+toward the boy, palm up, the thumb and little finger meeting across
+the palm and crossed, the remaining fingers straight out.
+
+"You mean, 'Be prepared'?" Jimmie asked.
+
+"'Be prepared,"' repeated the other, like one rehearsing a lesson.
+
+"Gee!" laughed the boy. "Here's a Boy Scout lingerin' in little old
+Peru! Now wouldn't that stop a clock?"
+
+"You just wait a minute," Jackson said, hopefully. "I think I can
+talk with this chap a little in Spanish."
+
+Then followed a great picking of words to match gestures, and
+gestures to explain words, during which the full salute of the Boy
+Scouts of America was often repeated by the Indian. Then Jackson
+said:
+
+"He says that there were Boy Scouts down here six months ago, and
+that he guided them through the mountain passes to the headwaters of
+the Beni river. From there they went through to the valley of the
+Amazon in a boat--a steam launch."
+
+Jimmie reached under his waistcoat collar and produced his Wolf
+badge, pointing to it with his finger inquiringly. The Indian shook
+his head.
+
+"Not Wolves," the boy said, in a moment. "Let's see if they were
+Black Bears."
+
+When a Black Bear badge which belonged to Jack Bosworth was shown
+the Indian still shook his head. Then he pointed to the sky and
+whirled his hand around significantly, finishing with a waving,
+flying motion.
+
+"I see!" cried Jimmie. "They were Eagles!"
+
+"This ought to help some," Jackson observed, his face growing more
+cheerful.
+
+"Of course it will," replied the boy. "Ask him if he wants to get
+out of this blasted country and go to New York. We'll take him if
+he'll get us out on the east slope before Ned gets back."
+
+Jackson talked with the Indian again, but did not seem to be able to
+come to terms with him.
+
+"He doesn't want to commit himself," the ex-cattleman said. "We'll
+have to wait until he thinks it over."
+
+The Indian seemed moody and sullen for the next few hours. When
+dawn came and the little fire which had blazed in the cavern all
+night went out, he was called away and another native placed on
+guard.
+
+"That settles it," Jimmie said. "We lose!"
+
+"I'm the losenest feller you ever seen," said Jackson. "I never won
+a bet in my life. You're unlucky to get dumped in a mess with me."
+
+About the time Ned and Lyman landed in Asuncion the boys in the
+cavern began looking for his return. They were not permitted to
+leave the cavern, but they watched the eastern sky intently every
+minute.
+
+They watched the sky, too, during the long days when Ned was in
+prison at Asuncion. Late on the afternoon of the 21st, as the
+reader knows, Ned searched the eastern slope for them but they did
+not see him. On the morning of the 23d they were taken from the
+cave and placed in full sight on the eastern slope, where they would
+be sure to be seen from the sky. They did not know what to make of
+this at first, but directly, when they saw Indians, heavily armed,
+stationed in hiding places all about them, they understood.
+
+Jimmie had expressed the situation exactly. The cowards were
+baiting their trap for Ned with his friends.
+
+Unless some means of warning him could be found, Ned would drop down

+CHAPTER XVIII
+
+THE END OF A LONG CHASE
+
+
+On the 23d of August the Nelson, with Ned, Jack, and Frank on board,
+was sweeping over the mountains and valleys of Bolivia and Peru
+toward the twin valleys in which Jimmie and Jackson had been left.
+Plenty of provisions and gasoline had been taken on at the Hamlin
+storehouse, and the lads were well equipped for a week's cruise in
+the air.
+
+They did not urge the aeroplane to its fullest speed, nor did they
+remain in the air longer than a couple of hours at a time. It had
+been decided to strike the eastern slope of the range just before
+dawn, so the Nelson was allowed to loiter on the way. Jack
+afterwards declared that Ned slept half the time!
+
+Had the first decision, to run to the twin valleys as swiftly as
+possible, been held to, the two prisoners, guarded on that eastern
+slope, would have seen the Nelson coming toward their relief.
+
+At the same time, on landing, Ned and his companions would have been
+confronted with armed Indians demanding immediate surrender. This
+would not have been according to the notions of the boys on the
+aeroplane, as they had figured that Jimmie and Jackson would be able
+to keep out of the hands of the Collins gang.
+
+The 23d dawned slowly, with the Nelson loitering over the great
+brown and green map of South America and the boys tiring their eyes
+looking for the glistening planes of the aeroplane. The captives
+were provided with food, but it was decidedly cold on the
+mountainside when night came.
+
+All that day and all that night the guards lay in wait in
+sequestered places, waiting for the Nelson. Although his only hope
+of immediate rescue lay in the arrival of the Nelson, Jimmie wished
+every minute of the time that Ned would in some manner be warned
+away from that dangerous locality.
+
+Just before dawn of the 24th Jimmie, who had fallen into a light
+slumber, felt Jackson pulling at his arm.
+
+"Wake up!" the man whispered. "There is a light in the sky!"
+
+Jimmie was on his feet in an instant. Away off over a parallel
+ridge to the east, a ridge not so high as the one on which they
+stood, and which formed only a slight elevation in the general
+slope, a single light twinkled and swung up and down in the half
+light between night and morning. "That's the Nelson, all right!"
+Jimmie declared. "Ned is coming! Good old Ned! Now, what can we
+do to keep him from being murdered?" the boy added, tearfully.
+
+"I give it up!" replied Jackson. "All we can do is to give them
+some signals and tell them to keep away."
+
+Jimmie sprang out to one of the guards, who already stood erect,
+watching the light with his gun in his hand. The guard looked
+curiously at Jimmie as he advanced, his hands clasping his
+shoulders, his body shivering as from extreme cold. The Indian was
+cold, too, so it did not take him long to make out the boy's
+meaning.
+
+Jimmie next pointed to sticks lying about, and to bunches of dry
+grass which stood in some of the crevices of the rocks. The guard
+nodded consent for a fire and Jimmie raced about like mad collecting
+principally dry grass.
+
+Jackson ran to help him, piling his gatherings all on one heap.
+
+"Make three piles!" Jimmie cried. "I want three fires! Three
+bright fires! Make three heaps!"
+
+The three heaps grew fast. They were not arranged in a row on a
+level, but mounted one above another on the slope. Jimmies idea was
+to so place the fires one above the other, some thing like notches
+cut in a tree trunk.
+
+The reason for this is apparent. Three fires in a line facing the
+point signaled to signal "Good News." Three notches cut in a tree
+trunk, one above another, mean "Important Warning!" Now the
+question was, would Ned understand that the fires represented
+warning notches, one above the other, and keep away until some safe
+plan for landing could be arranged?
+
+If he accepted the signal as "Good News" signs, he would drop down
+to death. If he read them as Jimmie intended he should, he would
+sail away and wait for a more favorable opportunity.
+
+When the three fires were going the Indian guards gathered about in
+order to warm themselves. Jimmie and Jackson hovered near them,
+too, but they never shifted their eyes from the light in the sky.
+
+The Nelson hovered over the elevation to the east for a second, and
+then, much to the amazement of the lad, whirled about and shot
+downward, out of sight. The guards watched the light as long as it
+showed and then turned to the fires again.
+
+Daylight came swiftly, and a finger of sunlight lay on the crest of
+the mountains when the' machine was in the air again. It was,
+perhaps, three miles away, across deep and dangerous canyons which
+it would require hours of the hardest kind of traveling to cross on
+foot.
+
+Sailing low, almost touching minor elevations at times, the great
+airship came on, straight to the spot where the boys stood--where
+the Indians awaited them with guns in their hands!
+
+In a moment Jimmie saw why this course was being taken. Unless the
+rascals in the twin valleys had seen the light when it first
+appeared they would not see it at all, for the bulk of the mountain
+shut off their view of the rough country over which Ned was
+traveling.
+
+Ned did not seem to mind the fire signals. Perhaps, Jimmie thought,
+he had recognized the warning as a "Good News" signal. In that case
+the boy thought, the end of everything, for them, would come right
+there!
+
+Moving slowly and softly, with little noise of motor or propeller,
+the Nelson approached the spot, circled about, and dropped in a
+little depression just below the place where Jimmie was standing.
+Then the strangest thing happened!
+
+The boy had expected to hear rifle shots, to see his friends
+attacked, perhaps murdered before his eyes. But the first one to
+spring from the machine was the Indian who had given the Boy Scout
+salute some days before!
+
+The Indians on guard saluted him gravely and stood eyeing the
+aeroplane critically. No hostile move was made. It was the
+strangest thing! Where had Ned taken the Indian up, and why had the
+latter volunteered to render this assistance?
+
+It was no use to wonder, so Jimmie and Jackson sprang toward the
+machine, grasped Ned by the hand, and swung into seats. The Indian
+who had piloted the Nelson to the place and prevented an attack by
+the guards, stood with his arms folded across his broad breast. For
+a moment Ned grasped his hand. The others followed, with what
+emotion may well be understood, and the Nelson was away, purring
+through the sweet air of the morning as if there were no perils at
+all in life!
+
+Later revelations showed that the Indian, wishing to protect the Boy
+Scouts, had made his way to the elevation where the Nelson had first
+dropped down, signaled to Ned, and informed him of the plans of the
+Collins people. Frank and Jack had been left farther down the
+slope, as it was feared that the Nelson would not be able to get
+away with so much weight to carry. It is almost needless to say
+that the Indian was rewarded for his loyalty to the Boy Scouts, and
+that he carried back with him enough money to make each of the
+guards a substantial present.
+
+When the Nelson first rose above the rim of the twin valleys shrill
+cries came from the direction of the cavern, and half a dozen shots
+were fired. But all to no purpose. The last the boys saw of
+Collins and his adherents they were shouting angrily at the Indians,
+who were rapidly disappearing from sight over the west wall.
+
+After a time the aeroplane dropped down again, and Jimmie's eyes
+nearly popped out of his head when he saw Jack and Frank sitting
+complacently on a rock watching him with grins on their faces. The
+greeting of the three boys may well be imagined.
+
+"You're a nice bunch!" Jimmie cried, after many handshakes and much
+pulling about. "We left you on the way to little old N.Y. Where
+you been?"
+
+"We just took a run in the Black Bear!" was the reply.
+
+"The Black Bear!" repeated the little fellow actually rubbing his
+eyes to see if he was awake. "Where is the Black Bear?"
+
+"Down in the Madeira river," laughed Ned, "and there's no knowing
+where she would have been by this time only for the--"
+
+"Cut it out, Ned!" broke in Jack. "Let us break it to him gently.
+He'll have fun enough with us without getting it all in a bunch!"
+
+Jackson was introduced to the two boys, and then a council of war
+was held. It was finally decided that Jackson should be taken to
+Sicuani in the Nelson and left there, with money enough to make his
+way out. Pedro was found at Sicuani and richly rewarded. He did
+not return to Lima.
+
+Then Ned was to return for the boys and proceed straight to
+Asuncion, where the search for the missing cattleman was to be
+renewed. This programme was carried out. Later the boys met
+Jackson in New York and royally entertained him at the Black Bear
+club room and saw that he secured a fine position.
+
+When the Nelson reached Asuncion Ned proceeded directly to the
+office of the president, taking the boys with him. There the story
+of the trip was told, and Frank and Jack saw to it that Ned's
+official position was made known to the head of the republic.
+
+"And so this Mr. Thomas Q. Collins is the man at the bottom of the
+trouble?" asked the official. "Well, he will be taken care of if he
+returns here. And this military chief? He shall be sent out of the
+country!"
+
+It transpired later on that the president had been deceived in the
+two men, and that Collins had secured the assistance of the general
+by false statements and by offers of large sums of money in case the
+cattle concession was taken from Lyman. A good many officials were
+found to be mixed up in the conspiracy, and there were numerous
+vacancies in the government service.
+
+"And now," the president said, after the whole truth was known, "the
+next thing to do is to find Lyman and restore him to his rights."
+
+"It seems to me," Ned suggested, "that this general ought to be able
+to produce him in Asuncion in a few hours' time."
+
+"It may be so," admitted the official. "At least, we'll see what
+can be done in that direction."
+
+Lyman was safe in his home in one day. When the general learned
+that it was the wish of the president that the cattleman should be
+brought forth, the thing was as good as accomplished.
+
+"It seems to me," Ned said to the boys, that night, "that this thing
+has been settled without much help from me. All the president
+needed was to be set right."
+
+"What he needed," laughed Jack, "was the proof that Collins had
+abducted Lyman, and that he was prepared to prevent his return to
+Asuncion until his concession had expired. Perhaps you can tell me
+how all this proof could have been obtained if you had not
+undertaken the job offered you by the Secret Service men at San
+Francisco?"
+
+"Of course he can't," Jimmie put in. "Lyman man would have died
+there in the mountains and Collins would have taken over his
+property. The president might have been in with the deal at first,
+but he certainly wasn't willing to stand for such coarse work."
+
+"And when Lyman didn't show up, his heirs would have demanded the
+property, and then there would have been an international quarrel--
+perhaps work for gunboats," Frank added. "I think the case was
+settled just right, and in the right way."
+
+"And what does this Lyman person say?" asked Jimmie.
+
+"Not a thing!" cried Jack. "He just offers Ned all the money there
+is in the world in the shape of a reward. I should have taken it!"
+
+"I know better," Ned commented. "We don't need his money, any more
+than we need the half million or so Collins offered us."
+
+"Wonder what Collins will do now?" asked Frank.
+
+"He'll duck!" replied Jimmie.
+
+The little fellow was right. Thomas Q. Collins was heard of no
+more, either in Paraguay or Peru. When Ned, leaving the others at
+Asuncion, speeded over to Lima he found Leroy and Mike lounging
+about the hotel, waiting anxiously for news from their chums. They
+had been released on the day following Collins' departure, there
+being no one to press the charge of assault and battery against
+them.
+
+Now there was work cut out for the Nelson. She carried Ned, Mike
+and Leroy over to Asuncion and then made two long trips to the
+little town on the Madeira where the Black Bear lay.
+
+The meeting between the boys and Harry was an enthusiastic one, and
+the latter pointed with a good deal of pride to the motor boat, good
+as new and as bright and clean as a new gold piece.
+
+After a few days spent exploring the country up the Beni, the boys
+started home, their errand satisfactorily accomplished. Jimmie
+decided to go with Jack, Frank, Harry and Mike in the motor boat,
+leaving the Nelson to Ned and Leroy.
+
+"One thing I'd like to do," Jimmie said, as the Black Bear lay
+waiting for the boys, "and that is to go up into that cannibal
+country and have some fun with the fellows who captured the Black
+Bear and made the occupants of it look like thirty cents in postage
+stamps!"
+
+"They never did capture the Black Bear!" yelled Frank. "They tried
+to, and got dynamited for their pains. That's what they got."
+
+"And of course," tormented the little fellow, "you wished the Nelson
+had stayed away, and left you all the glory--not!"
+
+"Well," Jack interposed, "we didn't get tied up in a mountain cave
+by a lot of cheap skates. We never got where we had to let an
+Indian get us out of a mess."
+
+"Rats!" shouted Jimmie. "Ned would have recognized our fire signals
+and remained away! We could have gotten off without the Indian."
+
+"You say it well!" laughed Frank. "I think that fire signal was
+punk!"
+
+And so the lads roasted each other all the way down the Amazon, with
+the Nelson sailing above them, dropping down at night and, perhaps,
+changing passengers each day.
+
+"I wish I had the frame of the Vixen," Leroy said, one day. "I
+could make a fine aeroplane out of it. Shame to have an airship
+smashed like that!"
+
+Ned pointed to the planes of the Nelson.
+
+"You've got quite a job making this little lady look like new," he
+said. "Those tent canvas planes look rather cheap."
+
+"I'll have the new planes in place in a week after we get back to
+New York," said the other.
+
+"And send the repair bill to the government," advised Ned. "It will
+be paid without a cross word."
+
+At the mouth of the Amazon the Black Bear was taken apart and packed
+aboard a fast steamer bound for New York. The five boys accompanied
+her, of course, while Ned and Leroy completed the trip home in the
+Nelson. When the four reached the Black Bear club room they found
+Ned there with a mass of letters and telegrams before him.
+
+"Look here, lads," he said, "we've got more trouble on hand. You
+know about the revolution in China, and all that? Well, there's a
+lot of gold which belongs to the republic been dumped in the sea,
+and I've got to go and help get it out!"
+
+"Let 'em get their own gold," Jimmie said.
+
+"But in this case, it is claimed that there was fraud in the
+shipment of gold, also, that the vessel carrying it was rammed for
+the purpose of concealing the fraud. Anyway, Uncle Sam wants me to
+look it up."
+
+"What's he got to do with it?" asked Frank.
+
+"Something connected with the sub-treasury," laughed Ned. "That is
+all I can say to you about it."
+
+"And how you goin' to get it?" demanded Jimmie.
+
+"By working with a submarine," was the reply.
+
+"Down in the bottom of the sea!" sang Frank.
+
+"Well," Ned said, presently, "figure the thing out for yourselves.
+Find out if you can get permission to go, and all that. The
+government will provide the submarine and all the supplies, of
+course, and land us near the spot we are to search."
+
+But the story of the search for the gold is quite another tale. It
+will be found in the third volume of this series, entitled:
+
+"Boy Scouts in a Submarine; or, Searching an Ocean Floor."

+
+We produce about two million dollars for each hour we work. The
+time it takes us, a rather conservative estimate, is fifty hours
+to get any eBook selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. Our
+projected audience is one hundred million readers. If the value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour in 2002 as we release over 100 new text
+files per month: 1240 more eBooks in 2001 for a total of 4000+
+We are already on our way to trying for 2000 more eBooks in 2002
+If they reach just 1-2% of the world's population then the total
+will reach over half a trillion eBooks given away by year's end.
+
+The Goal of Project Gutenberg is to Give Away 1 Trillion eBooks!
+This is ten thousand titles each to one hundred million readers,
