+<H3 ALIGN="center">
+An Appeal for Aid
+</H3>
+
+<P>
+Tom Swift, seated in his laboratory engaged in trying to solve a
+puzzling question that had arisen over one of his inventions, was
+startled by a loud knock on the door. So emphatic, in fact, was the
+summons that the door trembled, and Tom started to his feet in some
+alarm.
+</P>
+
+<P>
+"Hello there!" he cried. "Don't break the door, Koku!" and then he
+laughed. "No one but my giant would knock like that," he said to
+himself. "He never does seem able to do things gently. But I wonder why
+he is knocking. I told him to get the engine out of the airship, and
+Eradicate said he'd be around to answer the telephone and bell. I
+wonder if anything has happened?"
+</P>
+
+<P>
+Tom shoved back his chair, pushed aside the mass of papers over which
+he had been puzzling, and strode to the door. Flinging it open he
+confronted a veritable giant of a man, nearly eight feet tall, and big
+in proportion. The giant, Koku, for that was his name, smiled in a
+good-natured way, reminding one of an overgrown boy.
+</P>
+
+<P>
+"Master hear my knock?" the giant asked cheerfully.
+</P>
+
+<P>
+"Hear you, Koku? Say, I couldn't hear anything else!" exclaimed Tom.
+"Did you think you had to arouse the whole neighborhood just to let me
+know you were at the door? Jove! I thought you'd have it off the
+hinges."
+</P>
+
+<P>
+"If me break, me fix," said Koku, who, from his appearance and from his
+imperfect command of English, was evidently a foreigner.
+</P>
+
+<P>
+"Yes, I know you can fix lots of things, Koku," Tom went on, kindly
+enough. "But you musn't forget what enormous strength you have. That's
+the reason I sent you to take the engine out of the airship. You can
+lift it without using the chain hoist, and I can't get the chain hoist
+fast unless I remove all the superstructure. I don't want to do that.
+Did you get the engine out?"
+</P>
+
+<P>
+"Not quite. Almost, Master."
+</P>
+
+<P>
+"Then why are you here? Has anything gone wrong?"
+</P>
+
+<P>
+"No, everything all right, Master. But man come to machine shop and
+say he must have talk with you. I no let him come past the gate, but I
+say I come and call you."
+</P>
+
+<P>
+"That's right, Koku. Don't let any strangers past the gate. But why
+didn't Eradicate come and call me. He isn't doing anything, is he?
+Unless, indeed, he has gone to feed his mule, Boomerang."
+</P>
+
+<P>
+"Eradicate, he come to call you, but that black man no good!" and Koku
+chuckled so heartily that he shook the floor of the office.
+</P>
+
+<P>
+"What's the matter with Eradicate?" asked Tom, somewhat anxiously. "I
+hope you and he haven't had another row?" Eradicate had served Tom and
+his father long before Koku, the giant, had been brought back from one
+of the young inventor's many strange trips, and ever since then there
+had been a jealous rivalry between the twain as to who should best
+serve Tom.
+</P>
+
+<P>
+"No trouble, Master," said Koku. "Eradicate he start to come and tell
+you strange man want to have talk, but Eradicate he no come fast
+enough. So I pick him up, and I set him down by gate to stand on guard,
+and I come to tell you. Koku come quick!"
+</P>
+
+<P>
+"Oh, I knew it must be something like that!" exclaimed Tom in some
+vexation. "Now I'll have Eradicate complaining to me that you mauled
+him. Picked him up and set him down again."
+</P>
+
+<P>
+"Sure. One hand!" boasted the giant. "Eradicate him not be heavy. More
+as a sack of flour now."
+</P>
+
+<P>
+"No, poor Eradicate is getting pretty old and thin," commented Tom. "He
+can't move very quickly. But you should have let him come, Koku. It
+makes him feel badly when he thinks he can't be of service to me any
+more."
+</P>
+
+<P>
+"Man say he in hurry." The giant spoke softly, as though he felt the
+gentle rebuke Tom administered. "Koku run quick tell you&mdash;bang on door."
+</P>
+
+<P>
+"Yes, you banged all right, Koku. Well, it can't be helped, I reckon.
+Where is this strange man? Who is he? Did you ever see him before?"
+</P>
+
+<P>
+"Me no can tell, Master. Not sure. But him now be at the outer gate.
+Eradicate watch."
+</P>
+
+<P>
+"All right. I'll go and see who it is. I don't want any strangers
+poking around here, especially with the plans of my new gyroscope lying
+in plain view."
+</P>
+
+<P>
+Before he left the laboratory Tom swept into a desk drawer the mass of
+papers and blue prints, and locked the receptacle.
+</P>
+
+<P>
+"No use taking any chances," he remarked. "I've had too much trouble
+with people trying to get inside information about dad's and my
+patents. Now, Koku, I'll go and see this man."
+</P>
+
+<P>
+The buildings composing the plant of Tom Swift and his father at
+Shopton were enclosed by a high, board fence, and at one of the
+entrances was a sort of gate-house, where some one was always on guard.
+Only those who could give a good account of themselves, workmen in the
+plant, or those known to the sentinel were admitted.
+</P>
+
+<P>
+It happened that the colored man, Eradicate, was on guard at the gates
+this day when the stranger asked to see Tom. Koku, working on the
+airship engine not far away, saw the stranger. Hearing the man say he
+was in a hurry and noting the slow progress of the aged Eradicate, who
+was troubled with rheumatism, the giant took matters into his own hands.
+</P>
+
+<P>
+Tom Swift entered the gate-house and saw, seated in a chair, a man who
+was impatiently tapping the floor with his thick-soled shoe.
+</P>
+
+<P>
+"Looks like a detective or a policeman in disguise," thought Tom, for,
+almost invariably, members of this profession wear very thick-soled
+shoes. Opposite the stranger sat Eradicate, a much-injured look on his
+honest, black face.
+</P>
+
+<P>
+"Oh, Massa Tom!" exclaimed Eradicate, as soon as the young inventor
+entered. "Dat Koku he&mdash;he&mdash;he done gone and cotch me by de collar ob
+mah coat, an' den he lif' me up, an' he sot me down so hard&mdash;so
+hard&mdash;dat he jar loose all mah back teef!" and Eradicate opened his
+mouth wide to display his gleaming ivories.
+</P>
+
+<P>
+"Eradicate, he no can come quick. He walk like so fashion!" and Koku,
+who had followed the young inventor, imitated the limping gait of the
+colored man with such a queer effect that Tom could not help laughing,
+and the stranger smiled.
+</P>
+
+<P>
+"Ef I gits holt on yo'&mdash;ef I does, yo' great, big, overgrown lummox,
+Ah'll&mdash;Ah'll&mdash;" began the colored man, stammeringly.
+</P>
+
+<P>
+"There. That will do now!" interrupted Tom. "Don't quarrel in here.
+Koku, get back to that engine and lift out the motor. Eradicate, didn't
+father tell you to whitewash the chicken coops to-day?"
+</P>
+
+<P>
+"Dat's what he done, Massa Tom."
+</P>
+
+<P>
+"Well, go and see about that. I'll stay here for a while, and when I
+leave I'll call one of you, or some one else, to be on guard. Skip now!"
+</P>
+
+<P>
+Having thus disposed of the warring factions, Tom turned to the
+stranger and after apologizing for the little interruption, asked:
+</P>
+
+<P>
+"You wished to see me?"
+</P>
+
+<P>
+"If you're Tom Swift; yes."
+</P>
+
+<P>
+"Well, I'm Tom Swift," and the young owner of the name smiled.
+</P>
+
+<P>
+"I hope you will pardon a stranger for calling on you," resumed the
+man, "but I'm in a lot of trouble, and I think you are the only one who
+can help me out."
+</P>
+
+<P>
+"What sort of trouble?" Tom inquired.
+</P>
+
+<P>
+"Contracting trouble&mdash;tunnel blasting, to be exact. But if you have a
+few minutes to spare perhaps you will listen to my story. You will then
+be better able to understand my difficulty."
+</P>
+
+<P>
+Tom Swift considered a moment. He was used to having appeals for help
+made to him, and usually they were of a begging nature. He was often
+asked for money to help some struggling inventor complete his machine.
+</P>
+
+<P>
+In many cases the machines would have been of absolutely no use if
+perfected. In other cases the inventions were of the utterly hopeless
+class, incapable of perfection, like some perpetual motion apparatus.
+In these cases Tom turned a deaf ear, though if the inventor were in
+want our hero relieved him.
+</P>
+
+<P>
+But this case did not seem to be like anything Tom had ever met with
+before.
+</P>
+
+<P>
+"Contracting trouble&mdash;blasting," repeated the youth, as he mused over
+what he had heard.
+</P>
+
+<P>
+"That's it," the man went on. "Permit me to introduce myself" and he
+held out a card, on which was the name
+</P>
+
+<H3 ALIGN="center">
+MR. JOB TITUS
+</H3>
+
+<BR>
+
+<P>
+Down in the lower left-hand corner was a line:
+<BR><BR>
+"Titus Brothers, Contractors."
+</P>
+
+<P>
+"I am glad to meet you, Mr. Titus," Tom said warmly, offering his hand.
+"I don't know anything about the contracting business, but if you do
+blasting I suppose you use explosives, and I know a little about them."
+</P>
+
+<P>
+"So I have heard, and that's why I came to you," the contractor went
+on. "Now if you'll give me a few minutes of your time&mdash;"
+</P>
+
+<P>
+"You had better come up to the house," interrupted Tom. "We can talk
+more quietly there."
+</P>
+
+<P>
+Calling a young fellow who was at work near by to occupy the
+gate-house, Tom led Mr. Titus toward the Swift homestead, and, a little
+later, ushered him into the library.
+</P>
+
+<P>
+"Now I'll listen to you," the youth said, "though I can't promise to
+aid you."
+</P>
+
+<P>
+"I realize that," returned Mr. Titus. "This is a sort of last chance
+I'm taking. My brother and I have heard a lot about you, and when he
+wrote to me that he was unable to proceed with his contract of
+tunneling the Andes Mountains for the Peruvian government, I made up my
+mind you were the one who could help us if you would."
+</P>
+
+<P>
+"Tunneling the Andes Mountains!" exclaimed Tom.
+</P>
+
+<P>
+"Yes. The firm represented by my brother and myself have a contract to
+build a railroad for the Peruvian government. At a point some distance
+back in the district east of Lima, Peru, we are making a tunnel under
+the mountain. That is, we have it started, but now we can't advance any
+further."
+</P>
+
+<P>
+"Why not?"
+</P>
+
+<P>
+"Because of the peculiar character of the rock, which seems to defy the
+strongest explosive we can get. Now I understand you used a powder in
+your giant cannon that&mdash;"
+</P>
+
+<P>
+Mr. Titus paused in his explanation, for at that moment there arose
+such a clatter out on the front piazza as effectually to drown
+conversation. There was a noise of the hoofs of a horse, the fall of a
+heavy body, a tattoo on the porch floor and then came an excited shout:
+</P>
+
+<P>
+"Whoa there! Whoa! Stop! Look out where you're kicking! Bless my
+saddle blanket! Ouch! There I go!"
+</P>

+Explanations
+</H3>
+
+<P>
+"What in the world is that?" cried Mr. Job Titus, in alarm.
+</P>
+
+<P>
+Tom Swift did not answer. Instead he jumped up from his chair and ran
+toward the front door. Mr. Titus followed. They both saw a strange
+sight.
+</P>
+
+<P>
+Standing on the front porch, which he seemed to occupy completely, was
+a large horse, with a saddle twisted underneath him. The animal was
+looking about him as calmly as though he always made it a practice to
+come up on the front piazza when stopping at a house.
+</P>
+
+<P>
+Off to one side, with a crushed hat on the back of his head, with a
+coat split up the back, with a broken riding crop in one hand and a
+handkerchief in the other, sat a dignified, elderly gentleman.
+</P>
+
+<P>
+That is, he would have been dignified had it not been for his position
+and condition. No gentleman can look dignified with a split coat and a
+crushed hat on, sitting under the nose of a horse on a front piazza,
+with his raiment otherwise much disheveled, while he wipes his
+scratched and bleeding face with a handkerchief.
+</P>
+
+<P>
+"Bless my&mdash;bless my&mdash;" began the elderly gentleman, and he seemed at a
+loss what particular portion of his anatomy or that of the horse, to
+bless, or what portion of the universe to appeal to, for he ended up
+with: "Bless everything, Tom Swift!"
+</P>
+
+<P>
+"I heartily agree with you, Mr. Damon!" cried Tom. "But what in the
+world happened?"
+</P>
+
+<P>
+"That!" exclaimed Mr. Damon, pointing with his broken crop at the horse
+on the piazza. "I was riding him when he ran away&mdash;just as my
+motorcycle tried to climb a tree. No more horses for me! I'll stick to
+airships," and slamming his riding crop down on the porch floor with
+such force that the horse started back, Mr. Damon arose, painfully
+enough if the contortions on his face and his grunts of pain went for
+anything.
+</P>
+
+<P>
+"Let me help you!" begged Tom, striding forward. "Mr. Titus, perhaps
+you will kindly lead the horse down off the piazza?"
+</P>
+
+<P>
+"Certainly!" answered the tunnel contractor. "Whoa now!" he called
+soothingly, as the steed evinced a disposition to sit down on the side
+railing. "Steady now!"
+</P>
+
+<P>
+The horse finally allowed himself to be led down the broad front steps,
+sadly marking them, as well as the floor of the piazza, with his sharp
+shoes.
+</P>
+
+<P>
+"Ouch! Oh, my back!" exclaimed Mr. Damon, as Tom helped him to stand up.
+</P>
+
+<P>
+"Is it hurt?" asked Tom, anxiously.
+</P>
+
+<P>
+"No, I've just got what old-fashioned folks call a 'crick' in it,"
+explained the elderly horseman. "But it feels more like a river than a
+'crick.' I'll be all right presently."
+</P>
+
+<P>
+"How did it happen?" asked Tom, as he led his guest toward the hall.
+Meanwhile Mr. Titus, wondering what it was all about, had tied the
+horse to a post out near the street curb, and had re-entered the
+library.
+</P>
+
+<P>
+"I was riding over to see you, Tom, to ask you if you wouldn't go to
+South America with me," began Mr. Damon, rubbing his leg tenderly.
+</P>
+
+<P>
+"South America?" cried Tom, with a sudden look at Mr. Titus.
+</P>
+
+<P>
+"Yes, South America. Why, there isn't anything strange in that, is
+there? You've been to wilder countries, and farther away than that."
+</P>
+
+<P>
+"Yes, I know&mdash;it's just a coincidence. Go on."
+</P>
+
+<P>
+"Let me get where I can sit down," begged Mr. Damon. "I think that
+crick in my back is running down into my legs, Tom. I feel a bit weak.
+Let me sit down, and get me a glass of water. I shall be all right
+presently."
+</P>
+
+<P>
+Between them Tom and Mr. Titus assisted the horseman into an easy
+chair, and there, under the influence of a cup of hot tea, which Mrs.
+Baggert, the housekeeper, insisted on making for him, he said he felt
+much better, and would explain the reason for his call which had
+culminated in such a sensational manner.
+</P>
+
+<P>
+And while Mr. Damon is preparing his explanation I will take just a few
+moments to acquaint my new readers with some facts about Tom Swift, and
+the previous volumes of this series in which he has played such
+prominent parts.
+</P>
+
+<P>
+Tom Swift was the son of an inventor, and not only inherited his
+father's talents, but had greatly added to them, so that now Tom had a
+wonderful reputation.
+</P>
+
+<P>
+Mr. Swift was a widower, and he and Tom lived in a big house in
+Shopton, New York State, with Mrs. Baggert for a housekeeper. About the
+house, from time to time, shops and laboratories had been erected,
+until now there was a large and valuable establishment belonging to Tom
+and his father.
+</P>
+
+<P>
+The first volume of this series is entitled, "Tom Swift and His Motor
+Cycle." It was through a motor cycle that Tom became acquainted with
+Mr. Wakefield Damon, who lived in a neighboring town. Mr. Damon had
+bought the motor cycle for himself, but, as he said, one day in riding
+it the machine tried to climb a tree near the Swift house.
+</P>
+
+<P>
+The young inventor (for even then he was working on several patents)
+ministered to Mr. Damon, who, disgusted with the motor cycle, and
+wishing to reward Tom, let the young fellow have the machine.
+</P>
+
+<P>
+Tom's career began from that hour. For he learned to ride the motor
+cycle, after making some improvements in it, and from then on the youth
+had led a busy life. Soon afterward he secured a motor boat and from
+that it was but a step to an airship.
+</P>
+
+<P>
+The medium of the air having been conquered, Tom again turned his
+attention to the water, or rather, under the water, and he and his
+father made a submarine. Then he built an electric runabout, the
+speediest car on the road.
+</P>
+
+<P>
+It was when Ton Swift had occasion to send his wireless message from a
+lonely island where he had been shipwrecked that he was able to do Mr.
+and Mrs. Nestor a valuable service, and this increased the regard which
+Miss Mary Nestor felt for the young inventor, a regard that bid fair,
+some day, to ripen into something stronger.
+</P>
+
+<P>
+Tom Swift might have made a fortune when he set out to discover the
+secret of the diamond makers. But Fate intervened, and soon after that
+quest he went to the caves of ice, where he and his friends met with
+disaster. In his sky racer Tom broke all records for speed, and when he
+went to Africa to rescue a missionary, had it not been for his electric
+rifle the tide of battle would have gone against him and his party.
+</P>
+
+<P>
+Marvelous, indeed, were the adventures underground, which came to Tom
+when he went to look for the city of gold, but the treasure there was
+not more valuable than the platinum which Tom sought in dreary Siberia
+by means of his air glider.
+</P>
+
+<P>
+Tom thought his end had come when he fell into captivity among the
+giants; but even that turned out well, and he brought two of the giants
+away with him. Koku, one of the two giants, became devotedly attached
+to the lad, much to the disgust of Eradicate Sampson, the old negro who
+had worked for the Swifts for a generation, and who, with his mule
+Boomerang, "eradicated" from the place as much dirt as possible.
+</P>
+
+<P>
+With his wizard camera Tom did much to advance the cause of science.
+His great searchlight was of great help to the United States government
+in putting a stop to the Canadian smugglers, while his giant cannon was
+a distinct advance in ordnance, not excepting the great German guns
+used in the European war.
+</P>
+
+<P>
+When Tom perfected his photo telephone the last objection to rendering
+telephonic conversation admissible evidence in a law court was done
+away with, for by this invention a person was able to see, as well as
+to hear, over the telephone wire. One practically stood face to face
+with the person, miles away, to whom one was talking.
+</P>
+
+<P>
+The volume immediately preceding this present one is called: "Tom Swift
+and His Aerial Warship." The young inventor perfected a marvelous
+aircraft that was the naval terror of the seas, and many governments,
+recognizing what an important part aircraft were going to play in all
+future conflicts, were anxious to secure Tom's machine. But he was true
+to his own country, though his rivals were nearly successful in their
+plots against him.
+</P>
+
+<P>
+The Mars, which was the name of Tom's latest craft, proved to be a
+great success, and the United States government purchased it. It was
+not long after the completion of this transaction that the events
+narrated in the first chapter of this book took place.
+</P>
+
+<P>
+Mr. Damon and Tom had been firm friends ever since the episode of the
+motor cycle, and the eccentric gentleman (who blessed so many things)
+often went with Tom on his trips. Besides Mary Nestor, Tom had other
+friends. The one, after Miss Nestor, for whom he cared most (if we
+except Mr. Damon) was Ned Newton, who was employed in a Shopton bank.
+Ned also had often gone with Tom, though lately, having a better
+position, he had less time to spare.
+</P>
+
+<P>
+"Well, do you feel better, Mr. Damon?" asked Tom, after a bit.
+</P>
+
+<P>
+"Yes, very much, thank you. Bless my pen wiper! but I thought I was
+done for when I saw my horse bolt for your front stoop. He rushed up
+it, fell down, but, fortunately, I managed to get out of his way,
+though the saddle girth slipped. And all I could think of was that my
+wife would say: 'I told you so!' for she warned me not to ride this
+animal.
+</P>
+
+<P>
+"But he never ran away with me before, and I was in a hurry to get over
+to see you, Tom. Now then, let's get down to business. Will you go to
+South America with me?"
+</P>
+
+<P>
+"Whereabout in South America are you going, Mr. Damon, and why?" Tom
+asked.
+</P>
+
+<P>
+"To Peru, Tom."
+</P>
+
+<P>
+"What a coincidence!" exclaimed Mr. Titus.
+</P>
+
+<P>
+"I beg your pardon?" said Mr. Damon, interrogatively.
+</P>
+
+<P>
+"I said what a coincidence. I am going there myself."
+</P>
+
+<P>
+"Excuse me," interposed Tom, "I don't believe, in the excitement of the
+moment, I introduced you gentlemen. Allow me&mdash;Mr. Damon&mdash;Mr. Titus."
+</P>
+
+<P>
+The presentation over, Mr. Damon went on:
+</P>
+
+<P>
+"You see, Tom, I have lately invested considerable money in a wholesale
+drug concern. We deal largely in Peruvian remedies, principally the
+bark of the cinchona tree, from which quinine is made. Of late there
+has been some trouble over our concession from the Peruvian government,
+and the company has decided to send me down there to investigate.
+</P>
+
+<P>
+"Of course, as soon as I made up my mind to go I thought of you. So I
+came over to see if you would not accompany me. All went well until I
+reached your front gate. Then my horse became frightened by a yellow
+toy balloon some boy was blowing up in the street and bolted with me. I
+suppose if it had been a red or green balloon the effect would have
+been the same. However, here I am, somewhat the worse for wear. Now
+Tom, what do you say? Will you go to South America&mdash;to Peru&mdash;with me,
+and help look up this Quinine business?"
+</P>
+
+<P>
+Once more Mr. Titus and Tom looked at each other.

+A Face at the Window
+</H3>
+
+<P>
+"What is the matter?" asked Mr. Damon, catching the glance between Tom
+and the contractor. "Is there anything wrong with South America&mdash;Peru?
+I know they have lots of revolutions in those countries, but I don't
+believe Peru is what they call a 'banana republic'; is it?"
+</P>
+
+<P>
+"No," and Mr. Titus shook his head. "It isn't a question of
+revolutions."
+</P>
+
+<P>
+"But it's something!" insisted Mr. Damon. "Bless my ink bottle! but
+it's something. As soon as I mention Peru, Tom, you and Mr. Titus eye
+each other as if I'd said something dreadful. Out with it! What is it?"
+</P>
+
+<P>
+"It's just&mdash;just a coincidence," Tom said. "But go on, Mr. Damon.
+Finish what you have to say and then we'll explain."
+</P>
+
+<P>
+"Well, I guess I've told you all you need to know for the present. I
+went into this wholesale drug concern, hoping to make some money, but
+now, on account of the trouble down in Peru, we stand to lose
+considerable unless I can get back the cinchona concession."
+</P>
+
+<P>
+"What does that mean?" Tom asked.
+</P>
+
+<P>
+"Well, it means that our concern secured from the Peruvian government
+the right to take this quinine-producing bark from the trees in a
+certain tropical section. But there has been a change in the government
+in the district where our men were working, and now the privilege, or
+concession, has been withdrawn. I'm going down to see if I can't get it
+back. And I want you to go with me."
+</P>
+
+<P>
+"And I came here for very nearly the same thing," went on Mr. Titus.
+"That is where the coincidence comes in. It is strange that we should
+both appeal to Mr. Swift at the same time."
+</P>
+
+<P>
+"Well, Tom's a valuable helper!" exclaimed Mr. Damon. "I know him of
+old, for I've been on many a trip with him."
+</P>
+
+<P>
+"This is the first time I have had the pleasure of meeting him,"
+resumed the tunnel contractor, "but I have heard of him. I did not ask
+him to go to South America for us. I only wanted to get some superior
+explosive for my brother, who is in charge of driving the railroad
+tunnel through a spur of the Andes. I look after matters up North here,
+but I may have to go to Peru myself.
+</P>
+
+<P>
+"As I told Mr. Swift, I had read of his invention of the giant cannon
+and the special powder he used in it to send a projectile such a
+distance. The cannon is now mounted as one of the pieces of ordnance
+for the defense of the Panama Canal, is it not?" he asked Tom.
+</P>
+
+<P>
+The young inventor nodded in assent.
+</P>
+
+<P>
+"Having heard of you, and the wonderful explosive used in your big
+cannon," the contractor went on, "I wrote to my brother that I would
+try and get some for him.
+</P>
+
+<P>
+"You see," he resumed, "this is the situation. Back in the Andes
+Mountains, a couple of hundred miles east of Lima, the government is
+building a short railroad line to connect two others. If this is done
+it will mean that the products of Peru&mdash;quinine bark, coffee, cocoa,
+sugar, rubber, incense and gold can more easily be transported. But to
+connect the two railroad lines a big tunnel must be constructed.
+</P>
+
+<P>
+"My brother and I make a specialty of such work, and when we saw bids
+advertised for, our firm put in an estimate. There was some trouble
+with a rival firm, which also bid, but we secured the contract, and
+bound ourselves to have the tunnel finished within a certain time, or
+forfeit a large sum.
+</P>
+
+<P>
+"That was over a year ago. Since then our men, aided by the native
+Indians of Peru, have been tunneling the mountain, until, about a month
+back, we struck a snag."
+</P>
+
+<P>
+"What sort of snag?" Tom asked.
+</P>
+
+<P>
+"A snag in the shape of extra hard rock," replied the tunnel
+contractor. "Briefly, Paleozoic rocks make up the eastern part of the
+Andean Mountains in Peru, while the western range is formed of Mesozoic
+beds, volcanic ashes and lava of comparatively recent date. Near the
+coast the lower hills are composed of crystalline rocks, syenite and
+granite, with, here and there, a strata of sandstone or limestone.
+These are, undoubtedly, relics of the lower Cretaceous age, and we, or
+rather, my brother, states that he has found them covered with marine
+Tertiary deposits.
+</P>
+
+<P>
+"Now this Mesozoic band varies greatly. Porphyritic tuffs and massive
+limestone compose the western chain of the Andes above Lima, while in
+the Oroya Valley we find carbonaceous sandstones. Some of the tuffs may
+be of the Jurassic age, though the Cretaceous period is also largely
+represented.
+</P>
+
+<P>
+"Now while these different masses of rock formation offer hard enough
+problems to the tunnel digger, still we are more or less prepared to
+meet them, and we figured on a certain percentage of them. Up to the
+present time we have met with just about what we expected, but what we
+did not expect was something we came upon when the tunnel had been
+driven three miles into the mountain."
+</P>
+
+<P>
+"What did you find?" asked Tom, who knew enough about geology to
+understand the terms used. Mr. Damon did not, however, and when Mr.
+Titus rolled off some of the technical words, the drug investor softly
+murmured such expressions as
+</P>
+
+<P>
+"Bless my thermometer! Bless my porous plaster!"
+</P>
+
+<P>
+"We found," resumed Mr. Titus, "after we had bored for a considerable
+distance into the mountain, a mass of volcanic rock which is so hard
+that our best diamond drills are dulled in a short time, and the
+explosives we use merely shatter the face of the cutting, and give us
+hardly any progress at all.
+</P>
+
+<P>
+"It was after several trials, and when my brother found that he was
+making scarcely any progress, compared to the energy of his men and the
+blasting, that he wrote to me, explaining matters. I at once thought of
+you, Tom Swift, and your powerful explosive, for I had read about it.
+</P>
+
+<P>
+"Now then, will you sell us some of your powder&mdash;explosive or whatever
+you call it&mdash;Mr. Swift, or tell us where we can get it? We need it
+soon, for we are losing valuable time."
+</P>
+
+<P>
+Mr. Titus paused to draw on a piece of paper a rough map of Peru, and
+the district where the tunnel was being constructed. He showed where
+the two railroad lines were, and where the new route would bring them
+together, the tunnel eliminating a big grade up which it would have
+been impossible to haul trains of any weight.
+</P>
+
+<P>
+"What do you say, Mr. Swift?" the contractor concluded. "Will you let
+us have some of your powder? Or, better still, will you come to Peru
+yourself? That would suit us immensely, for you could be right on the
+ground. And you could carry out your plan of going with your friend
+here," and Mr. Titus nodded toward Mr. Damon. "That is, if you were
+thinking of going."
+</P>
+
+<P>
+"Well, I was thinking of it," Tom admitted. "Mr. Damon and I have been
+on so many trips together that it seems sort of natural for us to 'team
+it.' I have never been to Peru, and I should like to see the country.
+There is only one matter though, that bothers me."
+</P>
+
+<P>
+"What is it?" asked Mr. Titus quickly. "If it is a question of money
+dismiss it from your mind. The Peruvian government is paying a large
+sum for this tunnel, and we stand to make considerable, even if we were
+the lowest bidders. We can afford to pay you well&mdash;that is, we shall be
+able to if we can complete the bore on time. That is what is bothering
+me now&mdash;the unexpected strata of hard rock we have met with, which
+seems impossible to blast. But I feel sure we can do it with the
+explosive used in your giant cannon."
+</P>
+
+<P>
+"That is just the point!" Tom exclaimed. "I am not so sure my explosive
+would do."
+</P>
+
+<P>
+"Why not?" the tunnel contractor asked. "It's powerful enough; isn't
+it?"
+</P>
+
+<P>
+"Yes, it is powerful enough, but whether it will have the right effect
+on volcanic rock is hard to say. I should like to see a rock sample."
+</P>
+
+<P>
+"I can telegraph to have some sent here to you," said Mr. Titus
+eagerly. "Meantime, here is a description of it. I can read you that";
+and, taking a letter from his pocket, he read to Tom a geological
+description of the hard rock.
+</P>
+
+<P>
+"Hum! Yes," mused Tom, as he listened. "It seems to be of the nature of
+obsidian."
+</P>
+
+<P>
+"Bless my watch chain!" cried Mr. Damon. "What's that?"
+</P>
+
+<P>
+"Obsidian is a volcanic rock&mdash;a sort of combination of glass and flint
+for hardness," Tom explained. "It is brittle, black in color, and the
+natives of the Admiralty Islands use it for tipping their spears with
+which they slay victims for their cannibalistic feasts."
+</P>
+
+<P>
+"Bless my&mdash;bless my ear-drums!" gasped Mr. Damon. "Cannibals!"
+</P>
+
+<P>
+"Obsidian was also used by the ancient Mexicans to make knives and
+daggers," Tom went on. "When Cortez conquered Mexico he found the
+priests cutting the hearts from their living victims with knives made
+from this volcanic glass-like rock, known as obsidian. It may be that
+your brother has met with a vein of that in the tunnel," Tom said to
+the contractor.
+</P>
+
+<P>
+"Possibly," admitted Mr. Titus.
+</P>
+
+<P>
+"In that case," Tom stated, "I may have to use a new kind of explosive.
+That used for my giant cannon would merely crumble the hard rock for a
+short distance."
+</P>
+
+<P>
+"Then will you accept the contract, and help us out?" asked Mr. Titus
+eagerly. "We will pay you well. Will you come to Peru and look over the
+ground?"
+</P>
+
+<P>
+"And kill two birds with one stone, and come with me also?" put in Mr.
+Damon.
+</P>
+
+<P>
+Tom pondered for a moment. He was about to answer when the tunnel
+contractor, who was looking from the library window, suddenly jumped
+from his chair crying:
+</P>
+
+<P>
+"There he is again! Once more dogging me!"
+</P>
+
+<P>
+As he rushed from the room, Tom and Mr. Damon had a glimpse of a face
+at one of the low library windows&mdash;a face that had an evil look. It
+disappeared as Mr. Titus ran from the room.

+</H3>
+
+<P>
+"Bless my looking glass, Tom, what does that mean?" exclaimed Mr.
+Damon. "That face!"
+</P>
+
+<P>
+"I don't know," answered the young inventor. "But the sight of some one
+looking in here seemed to disturb Mr. Titus. We must follow him."
+</P>
+
+<P>
+"Perhaps he saw your giant Koku looking in," suggested the odd, little
+man who blessed everything he could think of. "The sight of his face,
+to any one not knowing him, Tom, would be enough to cause fright."
+</P>
+
+<P>
+"It wasn't Koku who looked in the window," said Tom, decidedly. "It was
+some stranger. Come on."
+</P>
+
+<P>
+The young inventor and Mr. Damon hurried out after the tunnel
+contractor, who was running down the road that led in front of the
+Swift homestead.
+</P>
+
+<P>
+"He's chasing some one, Tom," called Mr. Damon.
+</P>
+
+<P>
+"Yes, I see he is. But who?"
+</P>
+
+<P>
+"I can't see any one," reported Mr. Damon, who had run down to the
+gate, at which his horse was still standing. Mr. Damon had washed the
+dirt from his hands and face, and was wearing one of Mr. Swift's coats
+in place of his own split one.
+</P>
+
+<P>
+Tom joined the eccentric man and together they looked down the road
+after the running Mr. Titus. They were in half a mind to join him, when
+they saw him pull up short, raise his hands as though he had given over
+the pursuit, and turn back.
+</P>
+
+<P>
+"I guess he got away, whoever he was," remarked Tom. "We'll walk down
+and meet Mr. Titus, and ask him what it all means."
+</P>
+
+<P>
+Shortly afterward they came up to the contractor, who was breathing
+heavily after his run, for he was evidently not used to such exercise.
+</P>
+
+<P>
+"I beg your pardon, Tom Swift, for leaving you and Mr. Damon in such a
+fashion," said Mr. Titus, "but I had to act quickly or lose the chance
+of catching that rascal. As it was, he got away, but I think I gave him
+a scare, and he knows that I saw him. It will make him more cautious in
+the future."
+</P>
+
+<P>
+"Who was it?" asked Tom.
+</P>
+
+<P>
+"Well, I didn't have as close a look as I could have wished for," the
+contractor said, as he walked back toward the house with Tom and Mr.
+Damon, "but I'm pretty sure the face that peered in at us through the
+library window was that of Isaac Waddington."
+</P>
+
+<P>
+"And who is he, if it isn't asking information that ought not be given
+out?" inquired Mr. Damon.
+</P>
+
+<P>
+"Oh, no, certainly. I can tell you," said the contractor. "Only
+perhaps we had better wait until we get back to the house.
+</P>
+
+<P>
+"Since one of their men was seen lurking around here there may be
+others," went on Mr. Titus, when the three were once more seated in the
+Swift library. "It is best to be on the safe side. The face I saw, I'm
+sure, was that of Waddington, who is a tool of Blakeson & Grinder,
+rival tunnel contractors. They put in a bid on this Andes tunnel, but
+we were lower in our figures by several thousand dollars, and the
+contract was awarded to us.
+</P>
+
+<P>
+"Blakeson & Grinder tried, by every means in their power, to get the
+job away from us. They even invoked the aid of some Peruvian
+revolutionists and politicians, but we held our ground and began the
+work. Since then they have had spies and emissaries on our trail,
+trying their best to make us fail in our work, so the Peruvian
+officials might abrogate the contract and give it to them.
+</P>
+
+<P>
+"But, so far, we've managed to come out ahead. This Waddington is a
+sort of spy, and I've found him dodging me several times of late. I
+suppose he wants to find out my plans so as to be ready to jump in the
+breach in case we fail."
+</P>
+
+<P>
+"Do you think your rivals had anything to do with the difficulties you
+are now meeting with in digging the tunnel?" asked Mr. Damon. Mr. Titus
+shook his head.
+</P>
+
+<P>
+"The present difficulties are all of Nature's doing," he said. "It's
+just the abnormally hard rock that is bothering us. Only for that we'd
+be all right, though we might have petty difficulties because of the
+mean acts of Blakeson & Grinder. But I don't fear them."
+</P>
+
+<P>
+"How do you think this Waddington, if it was he, knew you were coming
+here?" asked Tom.
+</P>
+
+<P>
+"I can only guess. My brother and I have had some correspondence
+regarding you, Tom Swift. That is, I announced my intention of coming
+to see you, and my brother wrote me to use my discretion. I wrote back
+that I would consult you.
+</P>
+
+<P>
+"Our main office is in New York, where we employ a large clerical and
+expert force. There is nothing to prevent one of our stenographers, for
+instance, turning traitor and giving copies of the letters of my
+brother and myself to our rivals.
+</P>
+
+<P>
+"Mind you, I don't say this was done, and I don't suspect any of our
+employees, but it would be an easy matter for any one to know my plans.
+I never thought of making a secret of them, or of my trip here. In some
+way Waddington found out about the last, and he must have followed me
+here. Then he sneaked up under the window, and tried to hear what we
+said."
+</P>
+
+<P>
+"Do you think he did?" asked Tom.
+</P>
+
+<P>
+"I wouldn't be surprised. We took no pains to lower our voices. But,
+after all, he hasn't learned much that he didn't know before, if he
+knew I was coming here. He didn't learn the secret of the explosive
+that must be used, and that is the vital thing. For I defy him, or any
+other contractor, to blast that hard rock with any known explosive.
+We've tried every kind on the market and we've failed. We'll have to
+depend on you, Tom Swift, to help us out with some of your giant cannon
+powder."
+</P>
+
+<P>
+"And I'm not sure that will work," said the young inventor. "I think
+I'll have to experiment and make a new explosive, if I conclude to go
+to Peru."
+</P>
+
+<P>
+"Oh, you'll go all right!" declared Mr. Titus with a smile. "I can see
+that you are eager for the adventures I am sure you'll find there, and,
+besides, your friend here, Mr. Damon, needs you."
+</P>
+
+<P>
+"That's what I do, Tom!" exclaimed the odd man. "Bless my excursion
+ticket, but you must come!"
+</P>
+
+<P>
+"I'll have to invent the new powder first," Tom said.
+</P>
+
+<P>
+"That's what I like to hear!" exclaimed Mr. Titus. "It shows you are
+thinking of coming with us."
+</P>
+
+<P>
+Tom only smiled.
+</P>
+
+<P>
+"I am so anxious to get the proper explosive," went on Mr. Titus, "that
+I would even purchase it from our rivals, Blakeson & Grinder, if I
+thought they had it. But I'm sure they have not, though they may think
+they can get it.
+</P>
+
+<P>
+"That may be the reason they are following me so closely. They may
+want to know just when we will fail, and have to give up the contract,
+and they may think they can step in and finish the work. But I don't
+believe, without your help, Tom Swift, that they can blast that hard
+rock, and&mdash;"
+</P>
+
+<P>
+"Well, I'll say this," interrupted Tom, "first come, first served with
+me, other things being equal. You have applied to me and, like a
+lawyer, I won't go over to the other side now. I consider myself
+retained by your firm, Mr. Titus, to invent some sort of explosive, and
+if I am successful I shall expect to be paid."
+</P>
+
+<P>
+"Oh, of course!" cried the contractor eagerly.
+</P>
+
+<P>
+"Very good," Tom went on. "You needn't fear that I'll help the other
+fellows. Now to get down to business. I must see some samples of this
+rock in order to know what kind of explosive force is needed to rend
+it."
+</P>
+
+<P>
+"I have some in New York," went on the contractor. "I'll have it sent
+to you at once. I would have brought it, only it is too heavy to carry
+easily, and I was not sure I could engage you."
+</P>
+
+<P>
+"Did that fellow&mdash;Waddington, I believe you called him&mdash;get away from
+you?" asked Mr. Damon.
+</P>
+
+<P>
+"Clean away," the contractor answered. "He was a better runner than I."
+</P>
+
+<P>
+"It doesn't matter much," Tom said. "He didn't hear anything that would
+benefit him, and I'll give my men orders to be on the lookout for him.
+What sort of fellow is he, Mr. Titus?"
+</P>
+
+<P>
+The contractor described the eavesdropper, and Mr. Damon exclaimed:
+</P>
+
+<P>
+"Bless my turkey wish-bone! I'm sure I passed that chap when I was
+riding over to see you a while ago, Tom."
+</P>
+
+<P>
+"You did?"
+</P>
+
+<P>
+"Yes, on the highway. He inquired the way to your place. But there was
+nothing strange in that, since you employ a number of men, and I
+thought this one was coming to look for work. I can't say I liked his
+appearance, though."
+</P>
+
+<P>
+"No, he isn't a very prepossessing individual," commented Mr. Titus.
+"Well, now what's the first thing to be done, Tom Swift?"
+</P>
+
+<P>
+"Get me some samples of the rock, so I can begin my experiments."
+</P>
+
+<P>
+"I'll do that. And now let us consider about going to Peru. For I'm
+sure you will be successful in your experiments, and will find for us
+just the powder or explosive we need."
+</P>
+
+<P>
+"We can go together." said Mr. Damon. "I shall certainly feel more at
+home in that wild country if I know Tom Swift is with me, and I will
+appreciate the help of you and your friends, Mr. Titus, in
+straightening out the tangles of our drug business."
+</P>
+
+<P>
+"I'll do all I can for you, Mr. Damon."
+</P>
+
+<P>
+The three then talked at some length regarding possible plans. Tom sent
+out word to one of his men to keep a sharp watch around the house and
+grounds, against the possible return of Waddington, but nothing more
+was seen of him, at least for the time being.
+</P>
+
+<P>
+Mr. Titus drew up a sort of tentative agreement with Tom, binding his
+firm to pay a large sum in case the young inventor was successful, and
+then the contractor left, promising to have the rock samples come on
+later by express.
+</P>
+
+<P>
+Mr. Damon, after blessing a few dozen more or less impersonal objects,
+took his departure, his fractious horse having quieted down in the
+meanwhile, and Tom was left to himself.
+</P>
+
+<P>
+"I wonder what I've let myself in for now," the youth mused, as he went
+back to his laboratory. "It's a new field for me&mdash;tunnel blasting.
+Well, perhaps something may come of it."
+</P>
+
+<P>
+But of the strange adventure that was to follow his agreement to help
+Mr. Titus, our hero, Tom Swift, had not the least inkling.
+</P>
+
+<P>
+Tom went back to his labors over the gyroscope problem, but he could
+arrive at no satisfactory conclusion, and, tossing aside the papers,
+covered with intricate figures, he exclaimed:
+</P>
+
+<P>
+"Oh, I'm going for a walk! This thing is getting on my nerves."
+</P>
+
+<P>
+He strolled through the Shopton streets, and as he reached the
+outskirts of the town, he saw just ahead of him the figure of a girl.
+Tom quickened his pace, and presently was beside her.
+</P>
+
+<P>
+"Where are you going, Mary?" he asked.
+</P>
+
+<P>
+"Oh, Tom! How you startled me!" she exclaimed, turning around. "I was
+just thinking of you."
+</P>
+
+<P>
+"Thanks! Something nice?"
+</P>
+
+<P>
+"I shan't tell you!" and she blushed. "But where are you going?"
+</P>
+
+<P>
+"Walking with you!"
+</P>
+
+<P>
+Tom was nothing if not bold.
+</P>
+
+<P>
+"Hadn't you better wait until you're asked?" she retorted,
+mischievously.
+</P>
+
+<P>
+"If I did I might not get an invitation. So I'm going to invite myself,
+and then I'm going to invite you in here to have an ice cream soda,"
+and he and Miss Nestor were soon seated at a table in a candy shop.
+</P>
+
+<P>
+Tom had nearly finished his ice cream when he glanced toward the door,
+and started at the sight of a man who was entering the place.
+</P>
+
+<P>
+"What's the matter?" asked Mary. "Did you drop some ice cream, Tom?"
+</P>
+
+<P>
+"No, Mary. But that man&mdash;"
+</P>
+
+<P>
+Mary turned in time to see an excited man hurry out of the candy shop
+after a hasty glance at Tom Swift.
+</P>
+
+<P>
+"Who was he?" the girl asked.
+</P>
+
+<P>
+"I&mdash;er&mdash;oh, some one I thought I knew, but I guess I don't," said Tom,
+quickly. "Have some more cream, Mary?"
+</P>
+
+<P>
+"No, thank you. Not now."
+</P>
+
+<P>
+Tom was glad she did not care for any, as he was anxious to get
+outside, and have a look at the man, for he thought he had recognized
+the face as the same that had peered in his window. But when he and
+Miss Nestor reached the front of the shop the strange man was not in
+sight.
+</P>
+
+<P>
+"I guess he came in to cool off after his run," mused Tom, "but when he
+saw me he didn't care about it. I wonder if that was Waddington? He's a
+persistent individual if it was he."
+</P>
+
+<P>
+"Are you undertaking any new adventures, Tom?" asked Mary.
+</P>
+
+<P>
+"Well, I'm thinking of going to Peru."
+</P>
+
+<P>
+"Peru!" she cried. "Oh, what a long way to go! And when you get there
+will you write to me? I'm collecting stamps, and I haven't any from
+Peru."
+</P>
+
+<P>
+"Is that&mdash;er&mdash;the only reason you want me to write?" asked Tom.
+</P>
+
+<P>
+"No," said Mary softly, as she ran up the walk.
+</P>
+
+<P>
+Tom smiled as he turned away.
+</P>
+
+<P>
+Three days later he received a box from New York. It contained the
+samples from the Andes tunnel, and Tom at once began his experiments to
+discover a suitable explosive for rending the hard stone.
+</P>
+
+<P>
+"It is compressed molten lava," said Mr. Swift. "You'll never get an
+explosive that will successfully blast that, Tom."
+</P>
+
+<P>
+"We'll see," declared the young inventor.

+Mary's Present
+</H3>
+
+<P>
+Outside a rudely-constructed shack, in the middle of a large field,
+about a mile away from the nearest of the buildings owned by Tom Swift
+and his father, were gathered a group of figures one morning. From the
+shack, trailing over the ground, were two insulated wires, which led to
+a pile of rocks and earth some distance off. Out of the temporary
+building came Koku, the giant, bearing in his arms a big rock, of
+peculiar formation.
+</P>
+
+<P>
+"That's it, Koku!" exclaimed Tom Swift. "Now don't drop it on your
+toes."
+</P>
+
+<P>
+"No, Master, me no drop," the giant said, as he strode off with the
+heavy load as easily as a boy might carry a stone for his sling-shot.
+</P>
+
+<P>
+Koku placed the big rock on top of the pile of dirt and stones and came
+back to the hut, just as Eradicate, the colored man-of-all-work,
+emerged. Koku was not looking ahead, and ran into Eradicate with such
+force that the latter would have fallen had not the giant clasped his
+big arms about him.
+</P>
+
+<P>
+"Heah now! Whut yo' all doin' t' me?" angrily demanded Eradicate. "Yo'
+done gone an' knocked de breff outen me, dat's whut yo' all done! I'll
+bash yo' wif a rock, dat's what I'll do!"
+</P>
+
+<P>
+Koku, laughing, tried to explain that it was all an accident, but
+Eradicate would not listen. He looked about for a stone to throw at the
+giant, though it was doubtful, with his feeble strength, and
+considering the great frame of the big man, if any damage would have
+been done. But Eradicate saw no rocks nearer than the pile in which
+ended the two insulated wires, and, with mutterings, the negro set off
+in that direction, shuffling along on his rheumatic legs.
+</P>
+
+<P>
+From the shack Tom Swift hailed:
+</P>
+
+<P>
+"Hi there, Rad! Come back! Where are you going?"
+</P>
+
+<P>
+"I'se gwine t' git a rock, Massa Tom, an' bash de haid ob dat big
+lummox ob a giant! He done knocked de breff outen me, so he did."
+</P>
+
+<P>
+"You come back from that stone pile!" Tom ordered. "I'm going to blow
+it up in a minute, and if you get too near you'll have the breath
+knocked out of you worse than Koku did it. Come back, I say!"
+</P>
+
+<P>
+But Eradicate was obstinate and kept on. Tom, who was adjusting a
+firing battery in the shack, laughed, and then in exasperation cried:
+</P>
+
+<P>
+"Koku, go and get him and bring him back. Carry him if he won't come
+any other way. I don't want the dear old chump to get the fright of his
+life, and he sure will if he goes too close. Bring him back!"
+</P>
+
+<P>
+"Koku bring, Master," was the giant's answer.
+</P>
+
+<P>
+He ran toward Eradicate, who, seeing his tormentor approaching,
+redoubled his shuffling pace toward the stone pile. But he was no match
+for the giant, who, ignoring his struggles, picked up Eradicate, and,
+flinging him over his shoulder like a sack of meal, brought him to the
+shack.
+</P>
+
+<P>
+"There him be, Master!" said the giant.
+</P>
+
+<P>
+"So I see," laughed Tom. "Now you stay here, Rad."
+</P>
+
+<P>
+"No, sah! No, sah, Massa Tom! I&mdash;I'se gwine t' git a rock an'&mdash;an'
+bash his haid&mdash;dat's what I'se gwine t' do!" and the colored man tried
+to struggle to his feet.
+</P>
+
+<P>
+"Look out now!" cried Tom, suddenly. "If things go right there won't be
+a rock left for you to 'bash' anybody's head with, Rad. Look out!"
+</P>
+
+<P>
+The three cowered inside the shack, which, though it was rudely made,
+was built of heavy logs and planks, with a fronting of sod and bags of
+sand.
+</P>
+
+<P>
+Tom turned a switch. There was a loud report, and where the stone pile
+had been there was a big hole in the ground, while the air was filled
+with fragments of rock and dirt. These came down in a shower on the
+roof of the shack, and Eradicate covered his ears with his trembling
+hands.
+</P>
+
+<P>
+"Am&mdash;am de world comin' to de end, Massa Tom?" he asked. "Am dat
+Gabriel's trump I done heah?"
+</P>
+
+<P>
+"No, you dear old goose!" laughed the young inventor. "That was just a
+charge of my new explosive&mdash;a small charge, too. But it seems to have
+done the work."
+</P>
+
+<P>
+He ran from the shack to the place where the rock pile had been, and
+picked up several small fragments.
+</P>
+
+<P>
+"Busted all to pieces!" exulted Tom Swift. "Not a piece left as big as
+a hickory nut. That's going some! I've got the right mixture at last.
+If an ounce did that, a few hundred pounds ought to knock that Andes
+tunnel through the mountain in no time. I'll telegraph to Mr. Titus."
+</P>
+
+<P>
+Leaving Koku and Rad to collect the wires and firing apparatus, there
+being no danger now, as no explosive was left in the shack, Tom made
+his way back to the house. His father met him.
+</P>
+
+<P>
+"Well, Tom," he asked, "another failure?"
+</P>
+
+<P>
+"No, Dad! Success! This time I turned the trick. I seem to have gotten
+just the right mixture. Look, these are some of the pieces left from
+the big rock&mdash;one of the samples Mr. Titus sent me. It was all cracked
+up as small as this," and he held out the fragments he had picked up in
+the field.
+</P>
+
+<P>
+Mr. Swift regarded them for a few moments.
+</P>
+
+<P>
+"That's better, Tom," he said. "I didn't think you could get an
+explosive that would successfully shatter that hard rock, but you seem
+to have done it. Have you the formula all worked out?"
+</P>
+
+<P>
+"All worked out, Dad. I only made a small quantity, but the same
+proportions will hold good for the larger amounts. I'm going to start
+in and make it now. And then&mdash;Ho! for Peru!"
+</P>
+
+<P>
+Tom struck an attitude, such as some old discoverer might have assumed,
+and then he hurried into the house to telephone a telegram to the
+Shopton office. The message was to Mr. Titus, and read:
+</P>
+
+<BR>
+
+<P>
+"Explosive success. Start making it at once. Ready for Peru in month's
+time."
+</P>
+
+<BR>
+
+<P>
+"Thirteen words," repeated Tom, as the operator called them back to
+him. "I hope that doesn't mean bad luck."
+</P>
+
+<P>
+The experiment which Tom Swift had just brought to a successful
+conclusion was one of many he had conducted, extending over several
+wearying weeks.
+</P>
+
+<P>
+As soon as Tom had received the samples of the rock he had begun to
+experiment. First he tried some of the explosive that was so successful
+in the giant cannon. As he had feared, it was not what was needed. It
+cracked the rock, but did not disintegrate it, and that was what was
+needed. The hard rock must be broken up into fragments that could be
+easily handled. Merely to crack it necessitated further explosions,
+which would only serve to split it more and perhaps wedge it fast in
+the tunnel.
+</P>
+
+<P>
+So Tom tried different mixtures, using various chemicals, but none
+seemed to be just right. The trials were not without danger, either.
+Once, in mixing some ingredients, there was an explosion that injured
+one man, and blew Tom some distance away. Fortunately for him, there
+was an open window in the direction in which he was propelled, and he
+went through that, escaping with only some cuts and bruises.
+</P>
+
+<P>
+Another time there was a hang-fire, and the explosive burned instead of
+detonating, so that one of the shops caught, and there was no little
+work in subduing the flames.
+</P>
+
+<P>
+But Tom would not give up, and finally, after many trials, he hit on
+what he felt to be the right mixture. This he took out to the big lot,
+and having made a miniature tunnel with some of the sample rock, and
+having put some of the explosive in a hole bored in the big chunk Koku
+carried, Tom fired the charge. The result we have seen. It was a
+success.
+</P>
+
+<P>
+A day after receiving Tom's message Mr. Titus came on and a
+demonstration was given of the powerful explosive.
+</P>
+
+<P>
+"Tom, that's great!" cried the tunnel contractor. "Our troubles are at
+an end now."
+</P>
+
+<P>
+But, had he known it, new ones were only just beginning.
+</P>
+
+<P>
+Tom at once began preparations for making the explosive on a large
+scale, as much of it would be needed in the Andes tunnel. Then, having
+turned the manufacturing end of it over to his men, Tom began his
+preparations for going to Peru.
+</P>
+
+<P>
+Mr. Damon was also getting ready, and it was arranged that he, with Tom
+and Mr. Titus, should take a vessel from San Francisco, crossing the
+continent by train. The supply of explosive would follow them by
+special freight.
+</P>
+
+<P>
+"We might have gone by Panama except for the slide in the canal," Tom
+said. "And I suppose I could take you across the continent in my
+airship, Mr. Titus, if you object to railroad travel."
+</P>
+
+<P>
+"No, thank you, Tom. If it's just the same to you, I'd rather stay on
+the ground," the contractor said. "I'm more used to it."
+</P>
+
+<P>
+A day or so before the start for San Francisco was to be made, Tom,
+passing a store in Shopton, saw something in the window he thought Mary
+Nestor would like. It was a mahogany work-box, of unique design,
+beautifully decorated, and Tom purchased it.
+</P>
+
+<P>
+"Shall I have it sent?" asked the clerk.
+</P>
+
+<P>
+"No, thank you," Tom answered.
+</P>
+
+<P>
+He knew the young lady who had waited on him, and, for reasons of his
+own, he did not want her to know that Mary was to get the box.
+</P>
+
+<P>
+Carrying the present to his laboratory, Tom prepared to wrap it up
+suitably to send to Mary, with a note. Just, however, as he was looking
+for a box suitable to contain the gift, he received a summons to the
+telephone. Mr. Titus, in New York, wanted to speak to him.
+</P>
+
+<P>
+"Here, Rad!" Tom called. "Just box this up for me, like a good fellow,
+and then take it to Miss Nestor at this address; will you?" and Tom
+handed his man the addressed letter he had written to Mary. "Be careful
+of it," Tom cautioned.
+</P>
+
+<P>
+"Oh, I'll be careful, Massa Tom," was the reply. "I'll shore be
+careful."
+</P>
+
+<P>
+And Eradicate was&mdash;all too careful.

+Mr. Nestor's Letter
+</H3>
+
+<P>
+"Got t' git a good strong box fo' dish yeah," murmured Eradicate, as he
+looked at the beautiful mahogany present Tom had turned over to him to
+take to Mary. "Mah Landy! Dat suttinly am nice; Ah! Um! Jest laik some
+ob de old mahogany furniture dat was in our fambily down Souf."
+Eradicate did not mean his family, exactly, but the one in which he had
+been a slave.
+</P>
+
+<P>
+"Yassum, dat shore am nice!" he went on, talking to himself as he
+admired the present. "I shore got t' put dat in a good box! An' dish
+year note, too. Let's see what it done say on de outside."
+</P>
+
+<P>
+Eradicate held the envelope carefully upside down, and read&mdash;or rather
+pretended to read&mdash;the name and address. Eradicate knew well enough
+where Mary lived, for this was not the first time he had gone there
+with messages from his young master.
+</P>
+
+<P>
+"Massa Tom shore am a fine writer," mused the negro, as he slowly
+turned the envelope around. "I cain't read nobody's writin' but hisen,
+nohow."
+</P>
+
+<P>
+Had Eradicate been strictly honest with himself, he would have
+confessed that he could not read any writing, or printing either. His
+education had been very limited, but one could show him, say, a printed
+sign and tell him it read "Danger" or "Five miles to Branchville," or
+anything like that, and the next time he saw it, Eradicate would know
+what that sign said. He seemed to fix a picture of it in his mind,
+though the letters and figures by themselves meant nothing to him. So
+when Tom told him the envelope contained the name and address of Miss
+Nestor, Eradicate needed nothing more.
+</P>
+
+<P>
+He rummaged about in some odds and ends in the corner of the
+laboratory, and brought out a strong, wooden box, which had a cover
+that screwed down.
+</P>
+
+<P>
+"Dat'll be de ticket!" Eradicate exclaimed. "De mahogany present will
+jest fit." Eradicate took some excelsior to pad the box, and then,
+dropping inside it the gift, already wrapped in tissue paper, he
+proceeded to screw on the cover.
+</P>
+
+<P>
+There was something printed in red letters on the outside box, but
+Eradicate could not read, so it did not trouble him.
+</P>
+
+<P>
+"Dat Miss Nestor shore will laik her present," he murmured. "An' I'll
+be mighty keerful ob it' laik Massa Tom tole me. He wouldn't trust dat
+big lummox Koku wif anyt'ing laik dis."
+</P>
+
+<P>
+Screwing on the cover, and putting a piece of wrapping paper outside
+the rough, wooden box, with the letter in his hand, Eradicate, full of
+his own importance, set off for Miss Nestor's house. Tom had not
+returned from the telephone, over which he was talking to Mr. Titus.
+</P>
+
+<P>
+The message was an important one. The contractor said he had received
+word from his brother in Peru that his presence was urgently needed
+there.
+</P>
+
+<P>
+"Could you arrange to get off sooner than we planned, Tom?" asked Mr.
+Titus. "I am afraid something has happened down there. Have you sent
+the first shipment of explosive?"
+</P>
+
+<P>
+"Yes, that went three days ago. It ought to arrive at Lima soon after
+we do. Why yes, I can start to-night if we have to. I'll find out if
+Mr. Damon can be with us on such short notice."
+</P>
+
+<P>
+"I wish you would," came from Mr. Titus. "And say, Tom, do you think
+you could take that giant Koku with you?"
+</P>
+
+<P>
+"Why?"
+</P>
+
+<P>
+"Well, I think he'd come in handy. There are some pretty rough
+characters in those Andes Mountains, and your big friend might be
+useful."
+</P>
+
+<P>
+"All right. I was thinking of it, anyhow. Glad you mentioned it. Now
+I'll call up Mr. Damon, and I'll let you know, in an hour or so, if he
+can make it."
+</P>
+
+<P>
+"Bless my hair brush, yes, Tom!" exclaimed the eccentric man, when told
+of the change in plans. "I can leave to-night as well as not."
+</P>
+
+<P>
+Word to this effect was sent on to Mr. Titus, and then began some
+hurrying on the part of Tom Swift. He told Koku to get ready to leave
+for New York at once, where he and the giant would join Mr. Titus and
+Mr. Damon, and start across the continent to take for steamer for Lima,
+Peru.
+</P>
+
+<P>
+"Rad, did you send that present to Miss Nestor?" asked Tom, later, as
+he finished packing his grip.
+</P>
+
+<P>
+"Yas, sah. I done did it. Took it mase'f!"
+</P>
+
+<P>
+"That's good! I guess I'll have to say good-bye to Mary over the
+telephone. I won't have time to call. I'm glad I thought of the
+present."
+</P>
+
+<P>
+Tom got the Nestor house on the wire. But Mary was not in.
+</P>
+
+<P>
+"There's a package here for her," said the girl's mother. "Did you&mdash;?"
+</P>
+
+<P>
+"Yes, I sent that," Tom said. "Sorry I won't be able to call and say
+good-bye, but I'm in a terrible rush. I'll see her as soon as I get
+back, and I'll write as soon as I arrive."
+</P>
+
+<P>
+"Do," urged Mrs. Nestor. "We'll all be glad to hear from you," for Tom
+and Mary were tentatively engaged to be married.
+</P>
+
+<P>
+Tom and Koku went on with their hurried preparations to leave for New
+York. Eradicate begged to be taken along, but Tom gently told the
+faithful old servant that it was out of the question.
+</P>
+
+<P>
+"Besides, Rad," he said, "it's dangerous in those Andes Mountains. Why,
+they have birds there, as big as cows, and they can swoop down and
+carry off a man your size."
+</P>
+
+<P>
+"Am dat shorely so, Massa Tom?"
+</P>
+
+<P>
+"Of course it is! You get the dictionary and read about the condors of
+the Andes Mountains."
+</P>
+
+<P>
+"Dat's what I'll do, Massa Tom. Birds as big as cows what kin pick up a
+man in dere beaks, an' carry him off! Oh, my! No, sah, Massa Tom! I
+don't want t' go. I'll stay right yeah!"
+</P>
+
+<P>
+Shortly before Tom and Koku departed for the railroad station, where
+they were to take a train for New York, Mary Nestor returned home.
+</P>
+
+<P>
+"Tom called you on the telephone to say good-bye," her mother informed
+her, "and said he was sorry he could not see you. But he sent some sort
+of gift."
+</P>
+
+<P>
+"Oh, how sweet of him!" Mary exclaimed. "Where is it?"
+</P>
+
+<P>
+"On the dining room table. Eradicate brought it with a note."
+</P>
+
+<P>
+Mary read the note first.
+</P>
+
+<P>
+In it Tom begged Mary to accept the little token, and to think of him
+when she used it.
+</P>
+
+<P>
+"Oh! I wonder what it can be," she cried in delight.
+</P>
+
+<P>
+"Better open it and see," advised Mr. Nestor, who had come in at that
+moment.
+</P>
+
+<P>
+Mary cut the string of the outside paper, and folded back the wrapper.
+A wooden box was exposed to view, a solid, oblong, wooden box, and on
+the top, in bold, red letters Mary, her father and her mother read:
+</P>
+
+<H3 ALIGN="center" STYLE="color: red">
+DYNAMITE! HANDLE WITH CARE!
+</H3>
+
+<BR>
+
+<P>
+"Oh! Oh!" murmured Mrs. Nestor.
+</P>
+
+<P>
+"Dynamite! Handle with care!" repeated Mr. Nestor, in a sort of dazed
+voice. "Quick! Get a pail of water! Dump it in the bathtub! Soak it
+good, and then telephone for the police. Dynamite! What does this mean?"
+</P>
+
+<P>
+He rushed toward the kitchen, evidently with the intention of getting a
+pail of water, but Mary clasped him by the arm.
+</P>
+
+<P>
+"Father!" she exclaimed. "Don't get so excited!"
+</P>
+
+<P>
+"Excited!" he cried. "Who's excited? Dynamite! We'll all be blown up!
+This is some plot! I don't believe Tom sent this at all! Look out! Call
+the police! Excited! Who's getting excited?"
+</P>
+
+<P>
+"You are, Daddy dear!" said Mary calmly. "This is some mistake. Tom did
+send this&mdash;I know his writing. And wasn't it Eradicate who brought this
+package, Mother?"
+</P>
+
+<P>
+"Yes, my dear. But your father is right. Let him put it in water, then
+it will be safe. Oh, we'll all be blown up. Get the water!"
+</P>
+
+<P>
+"No!" cried Mary. "There is some mistake. Tom wouldn't send me
+dynamite. There must be a present for me in there. Tom must have put
+it in the wrong box by mistake. I'm going to open it."
+</P>
+
+<P>
+Mary's calmness had its effect on her parents. Mr. Nestor cooled down,
+as did his wife, and a closer examination of the outer box did not seem
+to show that it was an infernal machine of any kind.
+</P>
+
+<P>
+"It's all a mistake, Daddy," Mary said. "I'll show you. Get me a screw
+driver."
+</P>
+
+<P>
+After some delay one was found, and Mr. Nestor himself opened the box.
+When the tissue paper wrappings of the mahogany gift were revealed he
+gave a sigh of relief, and when Mary undid the wrappings, and saw what
+Tom had sent her, she cried:
+</P>
+
+<P>
+"Oh, how perfectly dear! Just what I wanted! I wonder how he knew? Oh,
+I just love it!" and she hugged the beautiful box in her arms.
+</P>
+
+<P>
+"Humph!" exclaimed Mr. Nestor, a slowly gathering light of anger
+showing in his eyes. "It is a nice present, but that is a very poor
+sort of joke to play, in my estimation."
+</P>
+
+<P>
+"Joke! What joke?" asked Mary.
+</P>
+
+<P>
+"Putting a present in a box labeled Dynamite, and giving us such a
+scare," went on her father.
+</P>
+
+<P>
+"Oh, Father, I'm sure he didn't mean to do it!" Mary said, earnestly.
+</P>
+
+<P>
+"Well, maybe he didn't! He may have thought it a joke, and he may not
+have! But, at any rate, it was a piece of gross carelessness on his
+part, and I don't care to consider for a son-in-law a young man as
+careless as that!"
+</P>
+
+<P>
+"Oh, Daddy!" expostulated Mary.
+</P>
+
+<P>
+"Now, now! Tut, tut!" exclaimed Mr. Nestor. "It isn't your fault, Mary,
+but this Tom Swift must be taught a lesson. He was careless, if nothing
+worse, and, for all he knew, there might have been some stray bits of
+dynamite in that packing box. It won't do! It won't do! I'll write him
+a letter, and give him a piece of my mind!"
+</P>
+
+<P>
+And in spite of all his wife and his daughter could say, Mr. Nestor did
+write Tom a scathing letter. He accused him of either perpetrating a
+joke, or of being careless, or both, and he intimated that the less he
+saw of Tom at the Nestor home hereafter the better pleased he would be.
+</P>
+
+<P>
+"There! I guess that will make him wish he hadn't done it!" exclaimed
+Mr. Nestor, as he called a messenger and sent the letter to Tom's house.
+</P>
+
+<P>
+Mary and her mother did not know the contents of the note, but Mary
+tried to get Tom on the wire and explain. However, she was unable to
+reach him, as Tom was on the point of leaving.
+</P>
+
+<P>
+The messenger, with Mr. Nestor's letter, arrived just as our hero was
+receiving the late afternoon mail from the postman, and just as Tom and
+Koku were getting in an automobile to leave for the depot.
+</P>
+
+<P>
+"Good-bye, Dad!" Tom called. "Good-bye, Mrs. Baggert!" He thrust Mr.
+Nestor's letter, unopened, together with some other mail matter, which
+he took to be merely circulars, into an inner pocket, and jumped into
+the car.
+</P>
+
+<P>
+Tom and Koku were off on the first stage of their journey.

+Off for Peru
+</H3>
+
+<P>
+"Well, Tom Swift, you're on time I see," was Mr. Job Titus' greeting,
+when our hero, and Koku, the giant, alighted from a taxicab in New
+York, in front of the hotel the contractor had appointed as a meeting
+place.
+</P>
+
+<P>
+"Yes, I'm here."
+</P>
+
+<P>
+"Did you have a good trip?"
+</P>
+
+<P>
+"Oh, all right, yes. Nothing happened to speak of, though we were
+delayed by a freight wreck. Has Mr. Damon got here yet?"
+</P>
+
+<P>
+"Not yet, Tom. But I had a message saying he was on his way. Come on up
+to the rooms I have engaged. Hello, what's all the crowd here for?"
+asked the contractor in some surprise, for a throng had gathered at the
+hotel entrance.
+</P>
+
+<P>
+"I expect it's Koku they're staring at," announced Tom, and the giant
+it was who had attracted the attention. He was carrying his own big
+valise, and a small steamer trunk belonging to Tom, as easily as though
+they weighed nothing, the trunk being under one arm.
+</P>
+
+<P>
+"I guess they don't see men of his size outside of circuses," commented
+the contractor. "We can pretty nearly, though not quite match him, down
+in Peru though, Tom. Some of the Indians are big fellows."
+</P>
+
+<P>
+"We'll get up a wrestling match between one of them and Koku,"
+suggested Tom. "Come on!" he called to the giant, who was surrounded by
+a crowd.
+</P>
+
+<P>
+Koku pushed his way through as easily as a bull might make his way
+through a throng of puppies about his heels, and as Tom, Mr. Titus and
+the giant were entering the hotel corridor, the chauffeur of the
+taxicab called out with a laugh:
+</P>
+
+<P>
+"I say, boss, don't you think you ought to pay double rates on that
+chap," and he nodded in the direction of the giant.
+</P>
+
+<P>
+"That's right!" added some one in the crowd with a laugh. "He might
+have broken the springs."
+</P>
+
+<P>
+"All right," assented Tom, good-naturedly, tossing the chauffeur a
+coin. "Here you are, have a cigar on the giant."
+</P>
+
+<P>
+There was more laughter, and even Koku grinned, though it is doubtful
+if he knew what about, for he could not understand much unless Tom
+spoke to him in a sort of code they had arranged between them.
+</P>
+
+<P>
+"Sorry to have hastened your departure," began Mr. Titus when he and
+Tom sat in the comfortable hotel rooms, while Koku stood at a window,
+looking out at what to him were the marvelous wonders of the New York
+streets.
+</P>
+
+<P>
+"It didn't make any difference," replied the young inventor. "I was
+about ready to come anyhow. I just had to hustle a little," and he
+thought of how he had had to send Mary's present to her instead of
+taking it himself. As yet he was all unaware of the commotion it had
+caused.
+</P>
+
+<P>
+"Did you get the powder shipment off all right?"
+</P>
+
+<P>
+"Yes, and it will be there almost as soon as we. Other shipments will
+follow as we need them. My father will see to that."
+</P>
+
+<P>
+"I'm glad you hit on the right kind of powder," went on the contractor.
+"I guess I didn't make any mistake in coming to you, Tom."
+</P>
+
+<P>
+"Well, I hope not. Of course the explosive worked all right in
+experimental charges with samples of the tunnel rock. It remains to be
+seen what it will do under actual conditions, and in big service
+charges."
+</P>
+
+<P>
+"Oh, I've no doubt it will work all right."
+</P>
+
+<P>
+"What time do we leave here?" Tom asked.
+</P>
+
+<P>
+"At two-thirty this afternoon. We have just time to get a good dinner
+and have our baggage transferred to the Chicago limited. In less than a
+week we ought to be in San Francisco and aboard the steamer. I hope Mr.
+Damon arrives on time."
+</P>
+
+<P>
+"Oh, you can generally depend on him," said Tom. "I telephoned him,
+just before I started from Shopton, and he said&mdash;"
+</P>
+
+<P>
+"Bless my carpet slippers!" cried a voice outside the hotel apartment.
+"But I can find my way all right. I know the number of the room. No!
+you needn't take my bag. I can carry it my self!"
+</P>
+
+<P>
+"There he is!" laughed Tom, opening the door to disclose the eccentric
+gentleman himself, struggling to keep possession of his valise against
+the importunities of a bellboy.
+</P>
+
+<P>
+"Ah, Tom&mdash;Mr. Titus! Glad to see you!" exclaimed Mr. Damon. "I&mdash;I am a
+little late, I fear&mdash;had an accident&mdash;wait until I get my breath," and
+he sank, panting, into a chair.
+</P>
+
+<P>
+"Accident?" cried Tom. "Are you&mdash;?"
+</P>
+
+<P>
+"Yes&mdash;my taxicab ran into another. Nobody hurt though."
+</P>
+
+<P>
+"But you're all out of breath," said Mr. Titus. "Did you run?"
+</P>
+
+<P>
+"No, but I walked upstairs."
+</P>
+
+<P>
+"What! Seven flights?" exclaimed Tom. "Weren't the hotel elevators
+running?"
+</P>
+
+<P>
+"Yes, but I don't like them. I'd rather walk. And I did&mdash;carried my
+valise&mdash;bellboy tried to take it away from me every step&mdash;here you are,
+son&mdash;it wasn't the tip I was trying to get out of," and he tossed the
+waiting and grinning lad a quarter.
+</P>
+
+<P>
+"There, I'm better now," went on Mr. Damon, when Tom had given him a
+glass of water. "Bless my paper weight! The drug concern will have to
+vote me an extra dividend for what I've gone through. Well, I'm here,
+anyhow. How is everything?"
+</P>
+
+<P>
+"Fine!" cried Tom. "We'll soon be off for Peru!"
+</P>
+
+<P>
+They talked over plans and made sure nothing had been forgotten. Their
+railroad tickets had been secured by Mr. Titus so there was nothing
+more to do save wait for train-time.
+</P>
+
+<P>
+"I've never been to Peru," Tom remarked shortly before lunch. "What
+sort of country is it?"
+</P>
+
+<P>
+"Quite a wonderful country," Mr. Titus answered. "I have been very much
+interested in it since my brother and I accepted this tunnel contract.
+Peru seems to have taken its name from Peru, a small river on the west
+coast of Colombia, where Pizarro landed. The country, geographically,
+may be divided into three sections longitudinally. The coast region is
+a sandy desert, with here and there rivers flowing through fertile
+valleys. The sierra region is the Andes division, about two hundred and
+fifty miles in width."
+</P>
+
+<P>
+"Is that where we're going?" asked Tom.
+</P>
+
+<P>
+"Yes. And beyond the Andes (which in Peru consist of great chains of
+mountains, some very high, interspersed with table lands, rich plains
+and valleys) there is the montana region of tropical forests, running
+down to the valley of the Amazon.
+</P>
+
+<P>
+"That sounds interesting," commented Mr. Damon.
+</P>
+
+<P>
+"It is interesting," declared Mr. Titus. "For it is from this tropical
+region that your quinine comes, Mr. Damon, though you may not have to
+go there to straighten out your affairs. I think you can do better
+bargaining with the officials in Lima, or near there."
+</P>
+
+<P>
+"Are there any wild animals in Peru?" Tom inquired.
+</P>
+
+<P>
+"Well, not many. Of course there are the llamas and alpacas, which are
+the beasts of burden&mdash;almost like little camels you might say, though
+much more gentle. Then there is the wild vicuna, the fleece of which is
+made into a sort of wool, after which a certain kind of cloth is named.
+</P>
+
+<P>
+"Then there is the taruco, a kind of deer, the viscacha, which is a big
+rat, the otoc, a sort of wild dog, or fox, and the ucumari, a black
+bear with a white nose. This bear is often found on lofty mountain
+tops, but only when driven there in search of food.
+</P>
+
+<P>
+"The condors, of course, are big birds of prey in the Andes. You must
+have read about them; how they seem to lie in the upper regions of the
+air, motionless, until suddenly they catch sight of some dead animal
+far down below when they sweep toward it with the swiftness of the
+wink. There is another bird of the vulture variety, with wings of black
+and white feathers. The ancient Incas used to decorate their head
+dresses with these wing feathers."
+</P>
+
+<P>
+"Well, I'm glad I'm going to Peru," said Tom. "I never knew it was such
+an interesting country. But I don't suppose we'll have time to see much
+of it."
+</P>
+
+<P>
+"Oh, I think you will," commented Mr. Titus. "We don't always have to
+work on the tunnel. There are numerous holidays, or holy-days, which
+our Indian workers take off, and we can do nothing without them. I'll
+see that you have a chance to do some exploring if you wish."
+</P>
+
+<P>
+"Good!" exclaimed Tom. "I brought my electric rifle with me, and I may
+get a chance to pop over one of those bears with a white nose. Are they
+good to eat?"
+</P>
+
+<P>
+"The Indians eat them, I believe, when they can get them, but I
+wouldn't fancy the meat," said the contractor.
+</P>
+
+<P>
+Luncheon over, the three travelers departed with their baggage for the
+Chicago Limited, which left from the Pennsylvania Station at
+Twenty-third Street. As usual, Koku attracted much attention because of
+his size.
+</P>
+
+<P>
+The trip to San Francisco was without incident worth narrating and in
+due time our friends reached the Golden Gate where they were to go
+aboard their steamer. They had to wait a day, during which time Tom and
+Mr. Titus made inquiries regarding the first powder shipment. They had
+had unexpected good luck, for the explosive, having been sent on ahead
+by fast freight, was awaiting them.
+</P>
+
+<P>
+"So we can take it with us on the Bellaconda," said, Tom, naming the
+vessel on which they were to sail.
+</P>
+
+<P>
+The powder was safely stowed away, and our friends having brought their
+baggage aboard, putting what was wanted on the voyage in their
+staterooms, went out on deck to watch the lines being cast off.
+</P>
+
+<P>
+A bell clanged and an officer cried:
+</P>
+
+<P>
+"All ashore that's going ashore!"
+</P>
+
+<P>
+There were hasty good-byes, a scramble on the part of those who had
+come to bid friends farewell, and preparations were made to haul in the
+gangplank.
+</P>
+
+<P>
+Just as the tugs were slowly pushing against the Bellaconda to get her
+in motion to move her away from the wharf, there was a shout down the
+pier and a taxicab, driven at reckless speed, dashed up.
+</P>
+
+<P>
+"Wait a minute! Hold that gangway. I have a passenger for you!" cried
+the chauffeur.
+</P>
+
+<P>
+He pulled up with a screeching of brakes, and a man with a heavy black
+beard fairly leaped from the vehicle, running toward the plank which
+was all but cast off.
+</P>
+
+<P>
+"My fare! My fare!" yelled the taxicab driver.
+</P>
+
+<P>
+"Take it out of that! Keep the change!" cried the bearded man over his
+shoulder, tossing a crumpled bill to the chauffeur. And then, clutching
+his valise in a firm hand, the belated passenger rushed up the
+gangplank just in time to board the steamer which was moving away from
+the dock.
+</P>
+
+<P>
+"Close shave&mdash;that," observed Tom.
+</P>
+
+<P>
+"That's right," assented Mr. Titus.
+</P>
+
+<P>
+"Well, we're off for Peru!" exclaimed Mr. Damon, as the vessel moved
+down the bay.

+The Bearded Man
+</H3>
+
+<P>
+Travel to Tom and Mr. Damon presented no novelties. They had been on
+too many voyages over the sea, under the sea and even in the air above
+the sea to find anything unusual in merely taking a trip on a steamer.
+</P>
+
+<P>
+Mr. Titus, though he admitted he had never been in a submarine or
+airship, had done considerable traveling about the world in his time,
+and had visited many countries, either for business or pleasure, so he
+was an old hand at it.
+</P>
+
+<P>
+But to Koku, who, since he had been brought from the land where Tom
+Swift had been made captive, had gone about but little, everything was
+novel, and he did not know at what to look first.
+</P>
+
+<P>
+The giant was interested in the ship, in the water, in the passengers,
+in the crew and in the sights to be seen as they progressed down the
+harbor.
+</P>
+
+<P>
+And the big man himself was a source of wonder to all save his own
+party. Everywhere he went about the decks, or below, he was followed by
+a staring but respectful crowd. Koku took it all good-naturedly,
+however, and even consented to show his great strength by lifting heavy
+weights. Once when several sailors were shifting one of the smaller
+anchors (a sufficiently heavy one for all that) Koku pushed them aside
+with a sweep of his big arm, and, picking up the big "hook," turned to
+the second mate and asked:
+</P>
+
+<P>
+"Where you want him?"
+</P>
+
+<P>
+"Good land, man!" cried the astonished officer. "You'll kill yourself!"
+</P>
+
+<P>
+But Koku carried the anchor where it ought to go, and from then on he
+was looked up to with awe and admiration by the sailors.
+</P>
+
+<P>
+From San Francisco to Callao, Peru (the latter city being the seaport
+of Lima, which is situated inland), is approximately nine hundred
+miles. But as the Bellaconda was a coasting steamer, and would make
+several stops on her trip, it would be more than a week before our
+friends would land at Callao, then to proceed to Lima, where they
+expected to remain a day or so before striking into the interior to
+where the tunnel was being bored through the mountain.
+</P>
+
+<P>
+The first day was spent in getting settled, becoming used to their new
+surroundings, finding their places and neighbors at table, and in
+making acquaintances. There were some interesting men and women aboard
+the Bellaconda, and Tom Swift, Mr. Damon and Mr. Titus soon made
+friends with them. This usually came about through the medium of Koku,
+the giant. Persons seeing him would inquire about him, and when they
+learned he was Tom Swift's helper it was an easy topic with which to
+open conversation.
+</P>
+
+<P>
+Tom told, modestly enough, how he had come to get Koku in his escape
+from captivity, but Mr. Damon was not so simple in describing Tom's
+feats, so that before many days had passed our hero found himself
+regarded as a personage of considerable importance, which was not at
+all to his liking.
+</P>
+
+<P>
+"But bless my fountain pen!" cried Mr. Damon, when Tom objected to so
+much notoriety. "You did it all; didn't you?"
+</P>
+
+<P>
+"Yes, I know. But these people won't believe it."
+</P>
+
+<P>
+"Oh, yes they will!" said the odd man. "I'll take good care that they
+believe it."
+</P>
+
+<P>
+"If any one say it not so, you tell me!" broke Koku, shaking his huge
+fist.
+</P>
+
+<P>
+"No, I guess I'd better keep still," said Tom, with a laugh.
+</P>
+
+<P>
+The weather was pleasant, if we except a shower or two, and as the
+vessel proceeded south, tropical clothing became the order of the day,
+while all who could, spent most of their time on deck under the shade
+of awnings.
+</P>
+
+<P>
+"Did you ever hear anything more of that fellow, Waddington?" asked Tom
+of Mr. Titus one day.
+</P>
+
+<P>
+"Not a thing. He seems to have dropped out of sight."
+</P>
+
+<P>
+"And are your rivals, Blakeson & Grinder, making any trouble?"
+</P>
+
+<P>
+"Not that I've heard of. Though just what the situation may be down in
+Peru I don't know. I fancy everything isn't going just right or my
+brother would not be so anxious for me to come on in such a hurry."
+</P>
+
+<P>
+"Do you anticipate any real trouble?"
+</P>
+
+<P>
+Mr. Titus paused a moment before answering.
+</P>
+
+<P>
+"Well, yes," he said, finally, "I do!"
+</P>
+
+<P>
+"What sort?" asked Tom.
+</P>
+
+<P>
+"That I can't say. I'll be perfectly frank with you, Tom. You know I
+told you at the time that we were in for difficulties. I didn't want
+you to go into this thing blindly."
+</P>
+
+<P>
+"Oh, I'm not afraid of trouble," Tom hastened to assure his friend.
+"I've had more or less of it in my life, and I'm willing to meet it
+again. Only I like to know what kind it is."
+</P>
+
+<P>
+"Well, I can't tell you&mdash;exactly," went on the tunnel contractor.
+"Those rivals of ours, Blakeson & Grinder, are unscrupulous fellows.
+They feel very bitter about not getting the contract, I hear. And they
+would be only too glad to have us fail in the work. That would mean
+that they, as the next lowest bidders, would be given the job. And we
+would have to make up the difference out of our pockets, as well as
+lose all the work we have, so far, put on the tunnel."
+</P>
+
+<P>
+"And you don't want that to happen!"
+</P>
+
+<P>
+"I guess not, my boy! Well, it won't happen if we get there in time
+with this new explosive of yours. That will do the business I'm sure."
+</P>
+
+<P>
+"I hope so," murmured Tom. "Well, we'll soon see. And now I think I'll
+go and write a few letters. We are going to put in at Panama, and I can
+mail them there."
+</P>
+
+<P>
+Tom started for his stateroom, and rapidly put his hand in the inner
+pocket of his coat. He drew out a bundle of letters and papers, and, as
+he looked at them, a cry of astonishment came from his lips.
+</P>
+
+<P>
+"What's the matter?" asked Mr. Titus.
+</P>
+
+<P>
+"Matter!" cried Tom. "Why here's a letter from Mary&mdash;from Mr. Nestor,"
+he went on, as he scanned the familiar handwriting. "I never opened it!
+Let's see&mdash;when did I get that?"

+His memory went back to the day of his departure from Shopton when he
+had sent Mary the gift, and he recalled that the letter had arrived
+just as he was getting into the automobile.
+</P>
+
+<P>
+"I stuck it in my pocket with some other mail," he mused, "and I never
+thought of it again until just now. But this is the first time I've
+worn this coat since that day. A letter from Mr. Nestor! Probably Mary
+wrote, thanking me for the box, and her father addressed the envelope
+for her. Well, let's see what it says."
+</P>
+
+<P>
+Tom retired to the privacy of his stateroom to read the note, but he
+had not glanced over more than the first half of it before he cried out:
+</P>
+
+<P>
+"Dynamite! Great Scott! What does this mean? 'Gross carelessness! Poor
+idea of a joke! No person with your idea of responsibility will ever be
+my son-in-law!' Box labeled 'open with care!' Why&mdash;why&mdash;what does it
+all mean?"
+</P>
+
+<P>
+Tom read the letter over again, and his murmurs of astonishment were so
+loud that Mr. Damon, in the next room, called out:
+</P>
+
+<P>
+"What's the matter, Tom? Get bad news?"
+</P>
+
+<P>
+"Bad news? I should say so! Mary&mdash;her father&mdash;he forbids me to see her
+again. Says I tried to dynamite them all&mdash;or at least scare them into
+believing I was going to. I can't understand it!"
+</P>
+
+<P>
+"Tell me about it, Tom," suggested Mr. Damon, coming into Tom's
+stateroom. "Bless my gunpowder keg! what does it mean?"
+</P>
+
+<P>
+Thereupon Tom told of having purchased the gift for Mary, and of
+having, at the last minute, told Eradicate to put it in a box and
+deliver it at the Nestor home.
+</P>
+
+<P>
+"Which he evidently did," Tom went on, "but when it got there Mary's
+present was in a box labeled 'Dynamite. Handle with care.' I never sent
+that."
+</P>
+
+<P>
+Mr. Damon read over Mr. Nestor's letter which had lain so long in Tom's
+pocket unopened.
+</P>
+
+<P>
+"I think I see how it happened," said the old man. "Eradicate can't
+read; can he, Tom?"
+</P>
+
+<P>
+"No, but he pretends he can."
+</P>
+
+<P>
+"And did you have any empty boxes marked dynamite in your laboratory?"
+</P>
+
+<P>
+"Why yes, I believe I did. I used dynamite as one of the ingredients of
+my new explosive."
+</P>
+
+<P>
+"Well then, it's as clear as daylight. Eradicate, being unable to read,
+took one of the empty dynamite boxes in which to pack Mary's present.
+That's how it happened."
+</P>
+
+<P>
+Tom thought for a moment. Then he burst into a laugh.
+</P>
+
+<P>
+"That's it," he said, a bit ruefully. "That's the explanation. No
+wonder Mr. Nestor was roiled. He thought I was playing a joke. I'll
+have to explain. But how?"
+</P>
+
+<P>
+"By letter," said Mr. Damon.
+</P>
+
+<P>
+"Too slow. I'll send a wireless," decided Tom, and he began the
+composition of a message that cost him considerable in tolls before he
+had hit on the explanation that suited him.
+</P>
+
+<P>
+"That ought to clear the atmosphere," he said when the wireless had
+shot his message into the ether. "Whew! And to think, all this while,
+Mary and her folks have believed that I tried to play a miserable joke
+on them! My! My! I wonder if they'll ever forgive me. When I get hold
+of Eradicate&mdash;"
+</P>
+
+<P>
+"Better teach him to read if he's going to do up love packages,"
+interrupted Mr. Damon, dryly.
+</P>
+
+<P>
+"I will," decided the young inventor.
+</P>
+
+<P>
+The Bellaconda stopped at Panama and then kept on her way south. Soon
+after that she ran into a severe tropical storm, and for a time there
+was some excitement among the passengers. The more timid of them put on
+life preservers, though the captain and his officers assured them there
+was no danger.
+</P>
+
+<P>
+Tom and Mr. Titus, descending from the deck, whence they had been
+warned by one of the mates, were on their way to their stateroom,
+walking with some difficulty owing to the roll of the ship.
+</P>
+
+<P>
+As they approached their quarters the door of a stateroom farther up
+the passage opened, and a head was thrust out.
+</P>
+
+<P>
+"Will you send a steward to me?" a man requested. "I am feeling very
+ill, and need assistance."
+</P>
+
+<P>
+"Certainly," Tom answered, and at that moment he heard Mr. Titus utter
+an exclamation.
+</P>
+
+<P>
+"What is it?" asked Tom, for the man who had appealed for help, had
+withdrawn his head.
+</P>
+
+<P>
+"That&mdash;that man!" exclaimed the contractor. "That was Waddington, the
+tool of our rivals."
+</P>
+
+<P>
+"Waddington!" repeated Tom, with a look at the now closed door. "Why,
+the bearded man has that stateroom&mdash;the bearded man who so nearly lost
+the steamer. He isn't Waddington!"
+</P>
+
+<P>
+"And I tell you Waddington is in that room!" insisted the contractor.
+"I only saw the upper part of his face, but I'd know his eyes anywhere.
+Waddington is spying on us!"
+</P>

+<P>
+Tom Swift and Mr. Titus withdrew a little way down the corridor, around
+a bulkhead and out of sight of any one who might look out from the
+stateroom whence had come the appeal for help. But, at the same time,
+they could keep watch over it.
+</P>
+
+<P>
+"I tell you Waddington is in there!" insisted Mr. Titus, hoarsely
+whispering.
+</P>
+
+<P>
+"Well, perhaps he may be," admitted Tom. "But several times I have seen
+the bearded man going in there, and it's only a single stateroom, for
+it's so marked on the deck plan."
+</P>
+
+<P>
+"Waddington might be disguised with a false beard, Tom."
+</P>
+
+<P>
+"Yes, he might. But did the man who just now looked out have a beard?"
+</P>
+
+<P>
+"I couldn't tell, as I saw only the upper part of his face. But those
+were Waddington's shifty eyes, I'm positive."
+</P>
+
+<P>
+"If Waddington were on board don't you suppose you would have seen him
+before this?"
+</P>
+
+<P>
+"Not positively, no. If he and the bearded man are one and the same
+that would account for it. But I haven't noticed the bearded man once
+since he came aboard in such a hurry."
+</P>
+
+<P>
+"Nor have I, now that I come to think of it," Tom admitted. "However,
+there is an easy way to prove who is in there."
+</P>
+
+<P>
+"How?"
+</P>
+
+<P>
+"We'll knock on the door and go in."
+</P>
+
+<P>
+"Perhaps he won't let us."
+</P>
+
+<P>
+"He'll think it's the steward he called for. Come, you know Waddington
+better than I do. You knock and go in."
+</P>
+
+<P>
+"I don't know Waddington very well," admitted the contractor. "I have
+only seen him a few times, but I am sure that was he. But what shall I
+do when he sees I'm not the steward?"
+</P>
+
+<P>
+"Tell him you have sent for one. I'll go with the message, so it will
+be true enough. Even if you have only a momentary glance at him in
+close quarters you ought to be able to tell whether or not he has on a
+false beard, and whether or not it is Waddington."
+</P>
+
+<P>
+Mr. Titus considered for a moment, and then he said:
+</P>
+
+<P>
+"Yes, I guess that is a good plan. You go for the steward, Tom, and
+I'll see if I can get in that stateroom. But I'm sure I'm not mistaken.
+I'll find Waddington in there, perhaps in the person of the bearded
+man, disguised. Or else they are using a single stateroom as a double
+one." And while Tom went off down the pitching and rolling corridor to
+find a steward, Mr. Titus, not without some apprehension, advanced to
+knock on the door of the suspect.
+</P>
+
+<P>
+"If it is Waddington he'll know me at once, of course," thought the
+contractor, "and there may be a row. Well, I can't help it. The success
+of my brother and myself depends on finishing that tunnel, and we can't
+have Waddington, and those whose tool he is, interfering. Here goes!"
+</P>
+
+<P>
+He tapped on the door, and a faint voice called:
+</P>
+
+<P>
+"Come in!"
+</P>
+
+<P>
+The contractor entered, and saw the bearded man lying in his berth.
+</P>
+
+<P>
+"Is there anything I can do for you?" asked the contractor, bending
+close over the man. He wanted to see if the beard were false. Somewhat
+to his surprise the contractor saw that undoubtedly it was real.
+</P>
+
+<P>
+"Steward, will you kindly get me&mdash;Oh, you're not the steward!" the
+bearded man exclaimed.
+</P>
+
+<P>
+"No, my friend and I heard you call," replied the contractor. "He has
+gone for the steward, who will be here soon. Can I do anything for you
+in the meanwhile?"
+</P>
+
+<P>
+"No&mdash;not a thing!" was the rather snappish answer, and the man turned
+his face away. "I beg your pardon," he went on, as if conscious that he
+had acted rudely, "but I am suffering very much. The steward knows just
+what I want. I have had these attacks before. I am a poor sailor. If
+you will send the steward to me I will be obliged to you. He can fix me
+up."
+</P>
+
+<P>
+"Very well," assented Mr. Titus. "But if there is anything I can do&mdash;"
+</P>
+
+<P>
+At that moment footsteps and voices were heard in the corridor, and as
+the door of the bearded man's stateroom was opened, Mr. Titus had a
+glimpse of Tom and one of the stewards.
+</P>
+
+<P>
+"Yes, I'll look after him," the steward said "He's been this way
+before. Thank you, sir, for calling me."
+</P>
+
+<P>
+"I guess the steward has been well tipped," thought Tom. As Mr. Titus
+came out and the door was shut, the young inventor asked in a whisper,
+</P>
+
+<P>
+"Well, was it he?"
+</P>
+
+<P>
+The contractor shook his head.
+</P>
+
+<P>
+"No," he answered. "I never was more surprised in my life. I felt sure
+it was Waddington in there, but it wasn't. That man's beard is real,
+and while he has a look like Waddington about the eyes and upper part
+of his face, the man is a stranger to me. That is I think so, but in
+spite of all that, I have a queer feeling that I have met him before."
+</P>
+
+<P>
+"Where?" Tom inquired.
+</P>
+
+<P>
+"That I can't say," and the tunnel contractor shook his head. "Whew!
+That was a bad one!" he exclaimed, as the steamer pitched and tossed in
+an alarming manner.
+</P>
+
+<P>
+"Yes, the storm seems to be getting worse instead of better," agreed
+Tom. "I hope none of the cargo shifts and comes banging up against my
+new explosive. If it does, there'll be no more tunnel digging for any
+of us."
+</P>
+
+<P>
+"Better not mention the fact of the explosives on board," suggested Mr.
+Titus.
+</P>
+
+<P>
+"I won't," promised Tom. "The passengers are frightened enough as it
+is. But I watched the powder being stored away. I guess it is safe."
+</P>
+
+<P>
+The storm raged for two days before it began to die away. Meanwhile,
+nothing was seen, on deck or in the dining cabins, of the bearded man.
+</P>
+
+<P>
+Tom and Mr. Titus made some guarded inquiries of the steward who had
+attended the sick man, and from him learned that he was down on the
+passenger list as Senor Pinto, from Rio de Janeiro, Brazil. He was
+traveling in the interests of a large firm of coffee importers of the
+United States, and was going to Lima.
+</P>
+
+<P>
+"And there's no trace of Waddington?" asked Tom of Mr. Titus, as they
+were discussing matters in their stateroom one day.
+</P>
+
+<P>
+"Not a trace. He seems to have dropped out of sight, and I'm glad of
+it."
+</P>
+
+<P>
+"Perhaps Blakeson & Grinder have given up the fight against you."
+</P>
+
+<P>
+"I wish they had, though I don't look for any such good luck. But I'm
+willing to fight them, now that we have an even chance, thanks to your
+explosive."
+</P>
+
+<P>
+The storm blew itself out. The Bellaconda "crossed the line," and there
+was the usual horseplay among the sailors when Father Neptune came
+aboard to hold court. Those who had never before been below the equator
+were made to undergo more or less of an initiation, being lathered and
+shaved, and then pushed backward into a canvas tank of water on deck.
+</P>
+
+<P>
+While Tom enjoyed the voyage, with the possible exception of the storm,
+he was anxious, and so was Mr. Titus, for the time to come when they
+should get to the tunnel and try the effect of the new explosive. Mr.
+Damon found an elderly gentleman as fond of playing chess as was the
+eccentric man himself, and his days were fully occupied with castles,
+pawns, knights, kings, queens and so on. As for Koku he was taken in
+charge by the sailors and found life forward very agreeable.
+</P>
+
+<P>
+Senor Pinto had recovered from his seasickness, the steward told Tom
+and Mr. Titus, but still he kept to his stateroom.
+</P>
+
+<P>
+It was when the Bellaconda was within a day or two of Callao that a
+wireless message was received for Mr. Titus. It was from his brother.
+The message read:
+</P>
+
+<BR>
+
+<P>
+"Have information from New York office that rivals are after you. Look
+out for explosive."
+</P>
+
+<BR>
+
+<P>
+"What does that mean?" asked Tom.
+</P>
+
+<P>
+"Well, I presume it means our rival contractors know we have a supply
+of your new powder on board, and they may try to get it away from us."
+</P>
+
+<P>
+"Why?" Tom demanded.
+</P>
+
+<P>
+"To prevent our using it to complete the tunnel. In that case they'll
+get the secret of it to use for themselves, when the contract goes to
+them by default. Can we do anything to protect the powder, Tom?"
+</P>
+
+<P>
+"Well, I don't know that we'll need to while it's stowed away in the
+cargo. They can't get at it any more than we can, until the ship
+unloads. I guess it's safe enough. We'll just have to keep our eyes
+open when it's taken out of the hold, though."
+</P>
+
+<P>
+Tom and Mr. Titus, both of whom were fond of fresh air and exercise,
+had made it a practice to get up an hour before breakfast and take a
+constitutional about the steamer deck. They did this as usual the
+morning after the wireless warning was received, and they were standing
+near the port rail, talking about this, when they heard a thud on the
+deck behind them. Both turned quickly, and saw a round black object
+rolling toward them. From the object projected what seemed to be a
+black cord, and the end of this cord was glowing and smoking.
+</P>
+
+<P>
+For a moment neither Tom nor Mr. Titus spoke. Then, as a slow motion of
+the ship rolled the round black thing toward Tom, he cried:
+</P>
+
+<P>
+"It a bomb!"
+</P>
+
+<P>
+He darted toward it, but Mr. Titus pulled him back.
+</P>
+
+<P>
+"Run!" yelled the contractor.
+</P>
+
+<P>
+Before either of them could do anything, a queer figure of an elderly
+gentleman stepped partly from behind a deck-house, and stooped over the
+smoking object.
+</P>
+
+<P>
+"Look out!" yelled Mr. Titus, crouching low. "That's an explosive bomb!
+Toss it overboard!"

+
+<P>
+Fairly fascinated by the spluttering fuse, neither Tom nor Mr. Titus
+moved for a second, while the deadly fire crept on through the black
+string-like affair, nearer and nearer to the bomb itself.
+</P>
+
+<P>
+Then, just as Tom, holding back his natural fear, was about to thrust
+the thing overboard with his foot, hardly realizing that it might be
+even more deadly to the ship in the water than it was on the deck, the
+foot of the newcomer was suddenly thrust out from behind the
+deck-house, and the sizzling fuse was trodden upon.
+</P>
+
+<P>
+It went out in a puff of smoke, but the owner of the foot was not
+satisfied with that for a hand reached down, lifted the bomb, the fuse
+of which still showed a smouldering spark of fire, and calmly pulled
+out the "tail" of the explosive. It was harmless then, for the fuse,
+with a trail of smoke following, was tossed into the sea, and the
+little man came out from behind the deck-house, holding the unexploded
+bomb.
+</P>
+
+<P>
+For a moment neither Tom nor Mr. Titus could speak. They felt an
+inexpressible sense of relief. Then Tom managed to gasp out:
+</P>
+
+<P>
+"You&mdash;you saved our lives!"
+</P>
+
+<P>
+The little man who had stepped on the fuse, and had then torn it from
+the bomb, looked at the object in his hand as though it were the most
+natural thing in the world to pick explosives up off the deck of
+passenger steamers, as he remarked:
+</P>
+
+<P>
+"Well, perhaps I did. Yes, I think it would have gone off in another
+second or two. Rather curious; isn't it?"
+</P>
+
+<P>
+"Curious? Curious!" asked and exclaimed Mr. Titus.
+</P>
+
+<P>
+"Why, yes," went on the little man, in the most matter of fact tone.
+"You see, most explosive bombs are round, made that way so the force
+will be equal in all directions. But this one, you notice, has a bulge,
+or protuberance, on one side, so to speak. Very curious!
+</P>
+
+<P>
+"It might have been made that way to prevent its rolling overboard, or
+the bomb's walls might be weaker near that bulge to make sure that the
+force of the explosion would be in that direction. And the bulge was
+pointed toward you gentlemen, if you noticed."
+</P>
+
+<P>
+"I should say I did!" cried Mr. Titus. "My dear sir, you have put us
+under a heavy debt to you! You saved our lives! I&mdash;I am in no frame of
+mind to thank you now, but&mdash;"
+</P>
+
+<P>
+He strode over to the little man, holding out his hand.
+</P>
+
+<P>
+"No, no, I'd better keep it," went on the person who had rendered the
+bomb ineffective. "You might drop it you know. You are nervous&mdash;your
+hand shakes."
+</P>
+
+<P>
+"I want to shake hands with you!" exclaimed Mr. Titus&mdash;"to thank you!"
+</P>
+
+<P>
+"Oh, that's it. I thought you wanted the bomb. Shake hands? Certainly!"
+</P>
+
+<P>
+And while this ceremony was being gone through with, Tom had a moment
+to study the appearance of the man who had saved their lives. He had
+seen the passenger once or twice before, but had taken no special
+notice of him. Now he had good reason to observe him.
+</P>
+
+<P>
+Tom beheld a little, thin man, little in the sense of being of the
+"bean pole" construction. His head was as bald as a billiard ball, as
+the young inventor could notice when the stranger took off his hat to
+bow formally in response to the greeting of some ladies who passed,
+while Mr. Titus was shaking hands with him.
+</P>
+
+<P>
+The bald head was sunk down between two high shoulders, and when the
+owner wished to observe anything closely, as he was now observing the
+bomb, the head was thrust forward somewhat as an eagle might do. And
+Tom noticed that the eyes of the little man were as bright as those of
+an eagle. Nothing seemed to escape them.
+</P>
+
+<P>
+"I want to add my thanks to those of Mr. Titus for saving our lives,"
+said Tom, as he advanced. "We don't know what to make of it all, but
+you certainly stopped that bomb from going off."
+</P>
+
+<P>
+"Yes, perhaps I did," admitted the little man coolly and calmly, as
+though preventing bomb explosions was his daily exercise before
+breakfast.
+</P>
+
+<P>
+Tom and Mr. Titus introduced themselves by name.
+</P>
+
+<P>
+"I am Professor Swyington Bumper," said the bomb-holder, with a bow,
+removing his hat, and again disclosing his shiny bald head. "I am very
+glad to have met you indeed."
+</P>
+
+<P>
+"And we are more than glad," said Tom, fervently, as he glanced at the
+explosive.
+</P>
+
+<P>
+"Now that the danger is over," went on Mr. Titus, "suppose we make an
+investigation, and find out how this bomb came to be here."
+</P>
+
+<P>
+"Just what I was about to suggest," remarked Professor Bumper. "Bombs,
+such as this, do not sprout of themselves on bare decks. And I take it
+this one is explosive."
+</P>
+
+<P>
+"Let me look at it," suggested Tom. "I know something of explosives."
+</P>
+
+<P>
+It needed but a casual examination on the part of one who had done
+considerable experimenting with explosives to disclose the fact that it
+had every characteristic of a dangerous bomb. Only the pulling out of
+the fuse had rendered it harmless.
+</P>
+
+<P>
+"If it had gone off," said Tom, "we would both have been killed, or, at
+least, badly injured, Mr. Titus."
+</P>
+
+<P>
+"I believe you, Tom. And we owe our lives to Professor Bumper."
+</P>
+
+<P>
+"I'm glad I could be of service, gentlemen," the scientist remarked, in
+an easy tone. "Explosives are out of my line, but I guessed it was
+rather dangerous to let this go off. Have you any idea how it got
+here?"
+</P>
+
+<P>
+"Not in the least," said Tom. "But some one must have placed it here,
+or dropped it behind us."
+</P>
+
+<P>
+"Would any one have an object in doing such a thing?" the professor
+asked.
+</P>
+
+<P>
+Tom and Mr. Titus looked at one another.
+</P>
+
+<P>
+"Waddington!" murmured the contractor. "If he were on board I should
+say he might have done it to get us out of the way, though I would not
+go so far as to say he meant to kill us. It may be this bomb has only a
+light charge in it, and he only meant to cripple us."
+</P>
+
+<P>
+"We'll find out about that," said Tom. "I'll open it."
+</P>
+
+<P>
+"Better be careful," urged Mr. Titus.
+</P>
+
+<P>
+"I will," the young inventor promised. "I beg your pardon," he went on
+to Professor Bumper. "We have been talking about something of which you
+know nothing. Briefly, there is a certain man who is trying to
+interfere in some work in which Mr. Titus and I are interested, and we
+think, if he were on board, he might have placed this bomb where it
+would injure us."
+</P>
+
+<P>
+"Is he here?" asked the professor.
+</P>
+
+<P>
+"No. And that is what makes it all the more strange," said Mr. Titus.
+"At one time I thought he was here, but I was mistaken."
+</P>
+
+<P>
+Tom took the now harmless bomb to his stateroom, and there, after
+taking the infernal machine apart, he discovered that it was not as
+dangerous as he had at first believed.
+</P>
+
+<P>
+The bomb contained no missiles, and though it held a quantity of
+explosive, it was of a slow burning kind. Had it gone off it would have
+sent out a sheet of flame that would have severely burned him and Mr.
+Titus, but unless complications had set in death would not have
+resulted.
+</P>
+
+<P>
+"They just wanted to disable us," said the contractor. "That was their
+game. Tom, who did it?"
+</P>
+
+<P>
+"I don't know. Did you ever see this Professor Bumper before?"
+</P>
+
+<P>
+"I never did."
+</P>
+
+<P>
+"And did it strike you as curious that he should happen to be so near
+at hand when the bomb fell behind us?"
+</P>
+
+<P>
+"I hadn't thought of that," admitted the contractor. "Do you mean that
+he might have dropped it himself?"
+</P>
+
+<P>
+"Well, I wouldn't go so far as to say that," replied Tom, slowly. "But
+I think it would be a good idea to find out all we can of Professor
+Swyington Bumper."
+</P>
+
+<P>
+"I agree with you, Tom. We'll investigate him."

+</H3>
+
+<P>
+Professor Swyington Bumper seemed to live in a region all by himself.
+Though he was on board the Bellaconda, he might just as well have been
+in an airship, or riding along on the back of a donkey, as far as his
+knowledge, or recognition, of his surroundings went. He seemed to be
+thinking thoughts far, far away, and he was never without a
+book&mdash;either a bound volume or a note-book. In the former he buried his
+hawk-like nose, and Tom, looking over his shoulder once, saw that the
+book was printed in curious characters, which, later, he learned were
+Sanskrit. If he had a note-book the bald-headed professor was
+continually jotting down memoranda in it.
+</P>
+
+<P>
+"I can hardly think of him as a conspirator against us," said Tom to
+Mr. Titus.
+</P>
+
+<P>
+"After you have been in the contracting business as long as I have
+you'll distrust every one," was the answer. "Waddington isn't on
+board, or I'd distrust him. That Spaniard, Senor Pinto, seems to be out
+of consideration, and there only remains the professor. We must watch
+him."
+</P>
+
+<P>
+But Professor Bumper proved to be above suspicion. Carefully guarded
+inquiries made of the captain, the purser and other ships' officers,
+brought out the fact that he was well known to all of them, having
+traveled on the line before.
+</P>
+
+<P>
+"He is making a search for something, but he won't say what it is," the
+captain said. "At first we thought it was gold or jewels, for he goes
+away off into the Andes Mountains, where both gold and jewels have been
+found. He never looks for treasure, though, for though some of his
+party have made rather rich discoveries, he takes no interest in them."
+</P>
+
+<P>
+"What is he after then?" asked Mr. Titus.
+</P>
+
+<P>
+"No one knows, and he won't tell. But whatever it is he has never found
+it yet. Always, when he comes back, unsuccessful, from a trip to the
+interior and goes back North with us, he will remark that he has not
+the right directions. That he must seek again.
+</P>
+
+<P>
+"Back he comes next season, as full of hope as before, but only to be
+disappointed. Each time he goes to a new place in the mountains where
+he digs and delves, so members of the parties he hires tell me, but
+with no success. He carries with him something in a small iron box,
+and, whatever this is, he consults it from time to time. It may be
+directions for finding whatever he is after. But there seems to be
+something wrong."
+</P>
+
+<P>
+"This is quite a mystery," remarked Tom.
+</P>
+
+<P>
+"It certainly is. But Professor Bumper is a fine man. I have known him
+for years."
+</P>
+
+<P>
+"This seems to dispose of the theory that he planted the bomb, and that
+he is one of the plotters in the pay of Blakeson & Grinder," said Mr.
+Titus, when he and Tom were alone.
+</P>
+
+<P>
+"Yes, I guess it does. But who can have done it?"
+</P>
+
+<P>
+That was a question neither could answer.
+</P>
+
+<P>
+Tom had a theory, which he did not disclose to Mr. Titus, that, after
+all, the somewhat mysterious Senor Pinto might, in some way, be mixed
+up in the bomb attempt. But a close questioning of the steward on duty
+near the foreigner's cabin at the time disclosed the fact that Pinto
+had been ill in his berth all that day.
+</P>
+
+<P>
+"Well, unless the bomb fell from some passing airship, I don't see how
+it got on deck," said Tom with a shake of his head. "And I'm sure no
+airship passed over us."
+</P>
+
+<P>
+They had kept the matter secret, not telling even Mr. Damon, for they
+feared the eccentric man would make a fuss and alarm the whole vessel.
+So Mr. Damon, occasionally blessing his necktie or his shoe laces,
+played chess with his elderly gentleman friend and was perfectly happy.
+</P>
+
+<P>
+That Professor Bumper not only had kept his promise about not
+mentioning the bomb, but that he had forgotten all about it, was
+evident a day or two after the happening. Tom and Mr. Titus passed him
+on deck, and bowed cordially. The professor returned the salutation,
+but looked at the two in a puzzled sort of fashion.
+</P>
+
+<P>
+"I beg your pardon," he remarked, "but your faces are familiar, though
+I cannot recall your names. Haven't I seen you before?"
+</P>
+
+<P>
+"You have," said Tom, with a smile. "You saved our lives from a bomb
+the other day."
+</P>
+
+<P>
+"Oh, yes! So I did! So I did!" exclaimed Professor Bumper. "I felt
+sure I had seen you before. Are you all right?"
+</P>
+
+<P>
+"Yes. There haven't been any more bombs thrown at us," the contractor
+said. "By the way, Professor Bumper, I understand you are quite a
+traveler in the Andes, in the vicinity of Lima."
+</P>
+
+<P>
+"Yes, I have been there," admitted the bald-headed scientist in guarded
+tones.
+</P>
+
+<P>
+"Well, I am digging a tunnel in that vicinity," went on Mr. Titus, "and
+if you ever get near Rimac, where the first cutting is made, I wish you
+would come and see me&mdash;Tom too, as he is associated with me."
+</P>
+
+<P>
+"Rimac-Rimac," murmured the professor, looking sharply at the
+contractor. "Digging a tunnel there? Why are you doing that?" and he
+seemed to resent the idea.
+</P>
+
+<P>
+"Why, the Peruvian government engaged me to do it to connect the two
+railroad lines," was the answer. "Do you know anything about the place?"
+</P>
+
+<P>
+"Not so much as I hope to later on," was the unexpected answer. "As it
+happens I am going to Rimac, and I may visit your tunnel."
+</P>
+
+<P>
+"I wish you would," returned Mr. Titus.
+</P>
+
+<P>
+Later on, in their stateroom, the contractor remarked to the young
+inventor:
+</P>
+
+<P>
+"Sort of queer; isn't it?"
+</P>
+
+<P>
+"What?" asked Tom. "His not remembering us?"
+</P>
+
+<P>
+"No, though that was odd. But I suppose he is forgetful, or pretends to
+be. I mean it's queer he is going to Rimac."
+</P>
+
+<P>
+"What do you mean?" asked Tom.
+</P>
+
+<P>
+"Well, I don't know exactly what I mean," went on the tunnel
+contractor, "but our tunnel happens to start at Rimac, which is a small
+town at the base of the mountains."
+</P>
+
+<P>
+"Maybe the professor is a geologist," suggested Tom, "and he may want
+to get some samples of that hard rock."
+</P>
+
+<P>
+"Maybe," admitted Mr. Titus. "But I shall keep my eyes on him all the
+same. I'm not going to have any strangers, who happen to be around when
+bombs drop near us, get into my tunnel."
+</P>
+
+<P>
+"I think you're wrong to doubt Professor Bumper," Tom said.
+</P>
+
+<P>
+A few days after this, when Tom and Mr. Titus were casually discussing
+the weather on deck and wondering how much longer it would be before
+they reached Callao, Mr. Damon, who had been playing numberless games
+of chess, came up for a breath of air.
+</P>
+
+<P>
+"Mr. Damon," called Tom, "come over here and meet a friend of ours,
+Professor Bumper," and he was about to introduce them, for the two, as
+far as Tom knew, had not yet met. But no sooner had the professor and
+Mr. Damon caught sight of each other than there was a look of mutual
+recognition.
+</P>
+
+<P>
+"Bless my fountain pen!" cried the eccentric man. "If it isn't my old
+friend!"
+</P>
+
+<P>
+"Mr. Damon!" cried the professor. "I am delighted to see you again. I
+did not know you were on board!"
+</P>
+
+<P>
+"Nor I you. Bless my apple dumpling! Are you still after those Peruvian
+antiquities?"
+</P>
+
+<P>
+"I am, Mr. Damon. But I did not know you were acquainted with Mr.
+Swift."
+</P>
+
+<P>
+"Oh, Tom and I are old friends."
+</P>
+
+<P>
+"Professor Bumper saved the lives of Mr. Titus and myself," said Tom,
+"or at least he saved us from severe injury by a bomb."
+</P>
+
+<P>
+"Pray do not mention it, my friends," put in the professor, casually.
+"It was nothing."
+</P>
+
+<P>
+Of course he did not mean it just that way.
+</P>
+
+<P>
+Then, naturally, Mr. Damon had to be told all about the bomb for the
+first time, and his wonder was great. He blessed everything he could
+think of.
+</P>
+
+<P>
+"And to think it should be my old friend, Professor Bumper, who saved
+you," said the odd man to Tom and Mr. Titus later that day.
+</P>
+
+<P>
+"Do you know him well?" asked Mr. Titus.
+</P>
+
+<P>
+"Very well indeed. Our drug concern sells him many chemicals for his
+experiments."
+</P>
+
+<P>
+"Well, if you know him I guess he can't be what I thought he was," the
+contractor went on. "I'm glad to know it. Why is he going to the Andes?"
+</P>
+
+<P>
+"Oh, for many years he has been interested in collecting Peruvian
+antiquities. He has a certain theory in regard to something or other
+about their ancient civilization, but just what it is I have, at this
+moment, forgotten. Only I know you can thoroughly trust Professor
+Bumper, for a finer man never lived, though he is a bit absent-minded
+at times. But you will like him very much."
+</P>
+
+<P>
+Thus the last lingering doubt of Professor Bumper was removed. Mr.
+Damon told something of how the scientist had been honored by degrees
+from many colleges and was regarded as an authority on Peruvian matters.
+</P>
+
+<P>
+But who had placed the bomb on deck remained a mystery.
+</P>
+
+<P>
+In due time Callao, the seaport of Lima, was reached and our friends
+disembarked. Tom saw to the unloading of the explosive, which was to be
+sent direct to the tunnel at Rimac. Mr. Titus, Tom and Mr. Damon would
+remain in Lima a day or so.
+</P>
+
+<P>
+Professor Bumper disembarked with our friends, and stopped at the same
+hotel. Tom kept a lookout for Senor Pinto, but did not see him, and
+concluded that the Spaniard was ill, and would be carried ashore on a
+stretcher, perhaps.
+</P>
+
+<P>
+Lima, the principal city and capital of Peru, proved an interesting
+place. It was about eight miles inland and was built on an arid plain
+about five hundred feet above sea level. Yet, though it was on what
+might be termed a desert, the place, by means of irrigation, had been
+made into a beauty spot.
+</P>
+
+<P>
+Tom found the older part of the city was laid out with mathematical
+regularity, each street crossing the other at right angles. But in the
+new portions there was not this adherence to straightness.
+</P>
+
+<P>
+"Bless my transfer! Why, they have electric cars here!" exclaimed Mr.
+Damon, catching sight of one on the line between Callao and the capital.
+</P>
+
+<P>
+"What did you think they'd have?" asked Mr. Titus, "elephants or
+camels?"
+</P>
+
+<P>
+"I&mdash;I didn't just know," was the answer.
+</P>
+
+<P>
+"Oh, you'll find a deal of civilization here," the contractor said. "Of
+course much of the population is negro or Indian, but they are often
+rich and able to buy what they want. There is a population of over
+150,000, and there are two steam railroads between Callao and Lima,
+while there is one running into the interior for 130 miles, crossing
+the Andes at an elevation of over three miles. It is a branch of that
+road, together with a branch of the one running to Ancon, that I am to
+connect with a tunnel."
+</P>
+
+<P>
+Tom found some beautiful churches and cathedrals in Lima, and spent
+some time visiting them. He and Mr. Damon also visited, in the
+outskirts, the tobacco, cocoa and other factories.
+</P>
+
+<P>
+Three days after reaching the capital, Mr. Titus having attended to
+some necessary business while Mr. Damon set on foot matters connected
+with his affairs, it was decided to strike inland to Rimac, and to try
+the effect of Tom Swift's explosive on the tunnel.
+</P>
+
+<P>
+The journey was to be made in part by rail, though the last stages of
+it were over a rough mountain trail, with llamas for beasts of burden,
+while our friends rode mules.
+</P>
+
+<P>
+As Tom, Mr. Damon, Koku, and Mr. Titus were going to the railroad
+station they saw Professor Bumper also leaving the hotel.
+</P>
+
+<P>
+"I believe our roads lie together for a time," said the bald-headed
+scientist, "and, if you have no objections, I will accompany you."
+</P>
+
+<P>
+"Come, and welcome!" exclaimed Mr. Titus, all his suspicions now gone.
+</P>
+
+<P>
+"And it may be that you will be able to help me," the scientist went on.
+</P>
+
+<P>
+"Help you&mdash;how?" asked Tom.
+</P>
+
+<P>
+"I will tell you when we reach the Andes," was the mysterious answer.
+</P>
+
+<P>
+It was a day later when they left the train at a small station, and
+struck off into the foothills of the great Andes Mountains, where the
+tunnel was started, that the professor again mentioned his object.
+</P>
+
+<P>
+"Friends," he said, as he gazed up at the towering cliffs and crags, "I
+am searching for the lost city of Pelone, located somewhere in these
+mountains. Will you help me to find it?"
+</P>

+The Tunnel
+</H3>
+
+<P>
+Mr. Damon, of the three who heard Professor Bumper make this statement,
+showed the least sign of astonishment. It would have been more correct
+to say that he showed none at all. But Tom could not restrain himself.
+</P>
+
+<P>
+"The lost city of Pelone!" he exclaimed.
+</P>
+
+<P>
+"Is it here&mdash;in these mountains?" asked Mr. Titus.
+</P>
+
+<P>
+"I have reason to hope that it is," went on the professor. "The golden
+tablets are very vague, but I have tried many locations, and now I am
+about to try here. I hope I shall succeed. At any rate, I shall have
+agreeable company, which has not always been my luck on my previous
+expeditions seeking to find the lost city."
+</P>
+
+<P>
+"Oh, Professor, are you still on that quest?" asked Mr. Damon, in a
+matter-of-fact tone.
+</P>
+
+<P>
+"Yes, Mr. Damon, I am. And now that I look about me, and see the shape
+of these mountains, I feel that they conform more to the description on
+the golden plates than any location I have yet tried. Somehow I feel
+that I shall be successful here."
+</P>
+
+<P>
+"Did you know Professor Bumper was searching for a lost city of the
+Andes?" asked Tom, of his eccentric friend.
+</P>
+
+<P>
+"Why yes," answered Mr. Damon. "He has been searching for years to
+locate it."
+</P>
+
+<P>
+"Why didn't you tell us?" inquired Mr. Titus.
+</P>
+
+<P>
+"Why, I never thought of it. Bless my memorandum book! it never
+occurred to me. I did not think you would be interested. Tell them
+your story, Professor Bumper."
+</P>
+
+<P>
+"I will soon. Just now I must see to my equipment. The story will keep."
+</P>
+
+<P>
+And though Tom and Mr. Titus were both anxious to hear about the lost
+city, they, too, had much to do to get ready for the trip into the
+interior.
+</P>
+
+<P>
+The beginning of the tunnel under one of the smaller of the ranges of
+the Andes lay two days journey from the end of the railroad line. And
+the trip must be made on mules, with llamas as beasts of burden,
+transporting the powder and other supplies.
+</P>
+
+<P>
+"We'll only need to take enough food with us for the two days," said
+Mr. Titus. "We have a regular camp at the tunnel mouth, and my brother
+has supplies of grub and other things constantly coming in. We also
+have shacks to live in; but on this trip we will use tents, as the
+weather at this season is fine."
+</P>
+
+<P>
+It was quite a little expedition that set off up the mountain trail
+that afternoon, for they had arrived at the end of the railroad line
+shortly before dinner, and had eaten at a rather poor restaurant.
+</P>
+
+<P>
+Professor Bumper had made up his own exploring party, consisting of
+himself and three native Indian diggers with their picks and shovels.
+They were to do whatever excavating he decided was necessary to locate
+the hidden city.
+</P>
+
+<P>
+Several mules and llamas, laden with the new explosive, and burdened
+with camp equipment and food, and a few Indian servants made up the
+cavalcade of Tom, the contractor, Mr. Damon and Koku. The giant was
+almost as much a source of wonder to the Peruvians as he had been on
+board the ship. And he was a great help, too. For some of the Indians
+were under-sized, and could not lift the heavy boxes and packages to
+the backs of the beasts of burden.
+</P>
+
+<P>
+But Koku, thrusting the little men aside, grasped with one hand what
+two of them had tried in vain to lift, and set it on the back of mule
+or llama.
+</P>
+
+<P>
+The way was rough but they took their time to it, for the trail was an
+ascending one. Above and beyond them towered the great Andes, and Tom,
+gazing up into the sky, which in places seemed almost pierced by the
+snow-covered peaks, saw some small black specks moving about.
+</P>
+
+<P>
+"Condors," said Mr. Titus, when his attention was called to them. "Some
+of them are powerful birds, and they sometimes pick up a sheep and make
+off with it, though usually their food consists of carrion."
+</P>
+
+<P>
+They went into camp before the sun went down, for it grew dark soon
+after sunset, and they wanted to be prepared. Supper was made ready by
+the Indian helpers, and when this was over, and they sat about a camp
+fire, Tom said:
+</P>
+
+<P>
+"Now, Professor Bumper, perhaps you'll explain about the lost city."
+</P>
+
+<P>
+"I wish I could explain about it," began the scientist. "For years I
+have dreamed of finding it, but always I have been disappointed. Now,
+perhaps, my luck may change."
+</P>
+
+<P>
+"Do you think it may be near here?" asked Mr. Titus, motioning toward
+the dark and frowning peaks all about them.
+</P>
+
+<P>
+"It may be. The signs are most encouraging. In brief, the story of the
+lost city of Pelone is this. Thousands of years ago&mdash;in fact I do not
+know how many&mdash;there existed somewhere in Peru an ancient city that was
+the centre of civilization for this region. Older it was than the
+civilization of the Mexicans&mdash;the Montezumas&mdash;older and more cultured.
+</P>
+
+<P>
+"It is many years since I became interested in Peruvian antiquities,
+and then I had no idea of the lost city. But some of the antiques I
+picked up contained in their inscriptions references to Pelone. At
+first I conceived this to be a sort of god, a deity, or perhaps a
+powerful ruler. But as I went on in my work of gathering ancient
+things from Peru, I saw that the name Pelone referred to a city&mdash;a seat
+of government, whence everything had its origin.
+</P>
+
+<P>
+"Then I got on the track more closely. I examined ancient documents. I
+found traces of an ancient language and writings, different from
+anything else in the world. I managed to construct an alphabet and to
+read some of the documents. From them I learned that Pelone was a city
+situated in some fertile valley of the Andes. It had existed for
+thousands of years; it was the seat of learning and culture. Much light
+would be thrown on the lives of the people who lived in Peru before the
+present races inhabited it, if I could but locate Pelone.
+</P>
+
+<P>
+"Then I came across two golden tablets on which were graven the
+information that Pelone had utterly vanished."
+</P>
+
+<P>
+"How?" asked Tom.
+</P>
+
+<P>
+"The golden tablets did not say. They simply stated the fact that
+Pelone was lost, and one sentence read: 'He who shall find it again
+shall be richly rewarded.' But it is not for that that I seek. It is
+that I may give to the world the treasures it must contain&mdash;the
+treasures of an ancient civilization."
+</P>
+
+<P>
+"And how do you think the city disappeared?" asked Mr. Titus.
+</P>
+
+<P>
+"I do not know. Whether it was destroyed by enemies, whether it was
+buried under the ashes of a volcano, whether it still exists, deserted
+and solitary in some valley amid the mountain fastnesses of the Andes,
+I do not know. But I am certain the city once existed, and it may exist
+yet, though it may be in dust-covered ruins. That is what I seek to
+find. See! Here are the tablets telling about it. I got them from an
+old Peruvian grave."
+</P>
+
+<P>
+He took from a box two thin sheets of yellow metal. They were covered
+with curious marks, but Tom and the others could make nothing of them.
+Only Professor Bumper was able to decipher them.
+</P>
+
+<P>
+"And that is the story of the lost city of Pelone&mdash;as much as I know,"
+he said. "For years I have sought it. If I can find it I shall be
+famous, for I shall have added to human knowledge."
+</P>
+
+<P>
+"If the people of that city wrote on golden tablets, the yellow metal
+must have been plentiful," commented Mr. Titus. "You might strike a
+rich mine."
+</P>
+
+<P>
+"I have no use for riches," said the professor.
+</P>
+
+<P>
+"Well, I have," the contractor said, with a laugh. "That's why I'm
+putting through this tunnel. And if my brother and I don't do it we'll
+be in a bad way financially. We have struck traces of gold, but not in
+paying quantities. I should like to see this lost city of yours,
+Professor Bumper. It may contain gold."
+</P>
+
+<P>
+"You may have all the gold, if I am allowed to keep the antiquities we
+find," stipulated the scientist. "Then you will help me in my search?"
+</P>
+
+<P>
+"As much as we can spare time for from the tunnel work," promised Mr.
+Titus. "I'll instruct my men to keep their eyes open for any sign of
+ancient writings on the rocks we blast out."
+</P>
+
+<P>
+"Thank you," said the professor.
+</P>
+
+<P>
+The night passed uneventfully enough, if one excepts the mosquitoes
+which seemed to get through the nets, making life miserable for all.
+And once Tom thought he heard gruntings in the bush back of the tent,
+which noises might, he imagined, have been caused by a bear. Toward
+morning he heard an unearthly screech in the woods, and one of the
+Indians, tending the fire, grunted out a word which meant pumas.
+</P>
+
+<P>
+"I can see it isn't going to be dull here," Tom mused, as he turned
+over and tried to sleep.
+</P>
+
+<P>
+Breakfast made them all feel better, and they set off on the final
+stage of their journey.
+</P>
+
+<P>
+"If all goes well we'll be at the tunnel entrance and camp to-night,"
+said the contractor. "This second half of the trip is the roughest."
+</P>
+
+<P>
+There was no need of saying that, for it was perfectly evident. The
+trail was a most precarious one, and only a mule or llama could have
+traveled it. The mules were most sure-footed, but, as it was, one
+slipped, and came near falling over a cliff.
+</P>
+
+<P>
+But no real accident occurred, and finally, about an hour before
+sunset, the cavalcade turned down the slope and emerged on a level
+plain, which ended against the face of a great cliff.
+</P>
+
+<P>
+As Tom rode nearer the cliff he could make out around it groups of rude
+buildings, covered with corrugated iron. There was quite a settlement
+it seemed.
+</P>
+
+<P>
+Then, in the face of the cliff there showed something black&mdash;like a
+blot of ink, though more regular in outline.
+</P>
+
+<P>
+"The mouth of the tunnel," said Mr. Titus to Tom. "Come on over to the
+office and I'll introduce you to my brother. I guess he will be glad
+we've arrived."
+</P>
+
+<P>
+Tom dismounted from his mule, an example followed by the others.
+Professor Bumper gazed up at the great mountains and murmured:
+</P>
+
+<P>
+"I wonder if the lost city of Pelone lies among them?"
+</P>
+
+<P>
+Suddenly the silence of the evening was broken by a dull, rumbling
+sound.
+</P>
+
+<P>
+"Bless my court plaster!" cried Mr. Damon. "What's that?"
+</P>
+
+<P>
+"A blast," answered Mr. Titus. "But I never knew them to set off one so
+late before. I hope nothing is wrong!"
+</P>
+
+<P>
+And, as he spoke, panic-stricken men began running out of the mouth of
+the tunnel, while those outside hastened toward them, shouting and
+calling.

+by Tom, Mr. Damon and Koku. Professor Bumper started with them, but on
+the way he saw a curious bit of rock which he stopped to pick up and
+examine.
+</P>
+
+<P>
+At the entrance of the tunnel, from which came rushing dirt-stained and
+powder-blackened men, Mr. Titus was met by a man who seemed to be in
+authority.
+</P>
+
+<P>
+"Hello, Job!" he cried. "Glad you're back. We're in trouble!"
+</P>
+
+<P>
+"What's the matter?" was the question. "This is my brother Walter," he
+said. "This is Tom Swift and Mr. Damon," thus hurriedly he introduced
+them. "What happened, Walter?"
+</P>
+
+<P>
+"Premature blast. Third one this week. Somebody is working against us!"
+</P>
+
+<P>
+"Never mind that now," cried Job Titus. "We must see to the poor
+fellows who are hurt." "I guess there aren't many," his brother said.
+"They were on their way out when the charge went off. Some more of
+Blakeson & Grinder's work, I'll wager!"
+</P>
+
+<P>
+They were rushing in to the smoke-filled tunnel now, followed by Tom,
+Mr. Damon and Koku, who would follow his young master anywhere. Tom saw
+that the tunnel was lighted with incandescent lamps, suspended here and
+there from the rocky roof or sides. The electric lights were supplied
+with current from a dynamo run by a gasoline engine.
+</P>
+
+<P>
+"Where is it, Serato? Where was the blast?" asked Walter Titus, of a
+tall Indian, who seemed to be in some authority.
+</P>
+
+<P>
+"Back at second turn," was the answer, in fairly good English. "I go
+get beds."
+</P>
+
+<P>
+"He means stretchers," translated Job. "That's our Peruvian foreman. A
+good fellow, but easily scared."
+</P>
+
+<P>
+They ran on into the tunnel, Tom and Mr. Damon noticing that a small
+narrow-gage railroad was laid on the floor, mules being the motive
+power to bring out the small dump cars loaded with rock and dirt,
+excavated from the big hole.
+</P>
+
+<P>
+"Mind the turn!" called Job Titus, who was ahead of Tom and Mr. Damon.
+"It's rough here."
+</P>
+
+<P>
+Tom found it so, for he slipped over some pieces of rock, and would
+have fallen had not Koku held him up.
+</P>
+
+<P>
+"Thanks," gasped Tom, as on he ran.
+</P>
+
+<P>
+A little later he came to a place where a cluster of electric lights
+gave better illumination, and he could see it was there that the damage
+had been done.
+</P>
+
+<P>
+A number of men were lying on the dirt and rock floor of the tunnel,
+and some of them were bleeding. Others were staggering about as though
+shocked or stunned.
+</P>
+
+<P>
+"We must get the injured ones out of here!" cried Walter Titus. "Where
+are the men with stretchers?"
+</P>
+
+<P>
+"I sint that Spalapeen Serato for thim!" broke in a voice, rich in
+Irish brogue. "But he's thot stupid he might think I was after sindin'
+him fer wather!"
+</P>
+
+<P>
+"No, Tim. Serato is after the stretchers all right," said Walter. "We
+passed him on the way."
+</P>
+
+<P>
+"That's Tim Sullivan, our Irish foreman, though he has only a few of
+his own kind to boss," explained Job Titus in a whisper.
+</P>
+
+<P>
+Some of the workmen (all of whom save the few Irish referred to were
+Peruvian Indians) had now recovered from their shock, or fright, and
+began to help the Titus brothers, Tom, Mr. Damon and Koku in looking
+after the injured. Of these there were five, only two of whom were,
+seemingly, seriously hurt.
+</P>
+
+<P>
+"Me take them out," said Koku, and placing one gently over his left
+shoulder, and the other over his right, out of the tunnel he stalked
+with them, not waiting for the stretchers.
+</P>
+
+<P>
+And it was well he did so, for one man was in need of an immediate
+operation, which was performed at the rude hospital the contractors
+maintained at the tunnel mouth. The other man died as Koku was carrying
+him out, but the giant had saved one life.
+</P>
+
+<P>
+Serato, the Indian foreman, with some of his men now came in, and the
+other injured were carried out on stretchers, being attended to by the
+two doctors who formed part of the tunnel force. Among a large body of
+men some were always falling ill or getting hurt, and in that wild
+country a doctor had to be kept near at hand.
+</P>
+
+<P>
+When the excitement had died down, and it was found that one death
+would be the total toll of the accident and that the premature blast
+had done no damage to the tunnel, the two Titus brothers began to
+consider matters.
+</P>
+
+<P>
+Tom, Mr. Damon and the two contractors sat in the main office and
+talked things over. Koku was eating supper, though the others had
+finished, but, naturally, it took Koku twice as long as any one else.
+Professor Bumper was busy transcribing material in his note-book.
+</P>
+
+<P>
+"Well, I'm glad you've come back, Job," said his brother. "Things have
+been going at sixes and sevens here since you went to get some new kind
+of blasting powder. By the way, I hope you got it, for we are
+practically at a standstill."
+</P>
+
+<P>
+"Oh, I got it all right&mdash;some of Tom Swift's best&mdash;specially made for
+us. And, better still, I've brought Tom back with me."
+</P>
+
+<P>
+"So I see. Well, I'm glad he's here."
+</P>
+
+<P>
+"Now what about this accident to-day?" went on Job.
+</P>
+
+<P>
+"Well, as I said, it's the third this week. All of them seemed to be
+premature blasts. But I've sent for some of the fuses used. I'm going
+to get at the bottom of this. Here is Sullivan with them now. Come in,
+Tim," he called, as the Irishman knocked at the door.
+</P>
+
+<P>
+"Are they the fuses used in the blasts?" Walter asked.
+</P>
+
+<P>
+"They are, sor. An' they mostly burn five minutes, which is plenty of
+time fer all th' min t' git out of danger. Only this time th' fuse
+didn't seem to burn more than a minute, an' I lit it meself."
+</P>
+
+<P>
+"Let's see how long they burn now," suggested Job.
+</P>
+
+<P>
+One of the longer fuses was lighted. It spluttered and smoked, while
+the contractors timed it with their watches.
+</P>
+
+<P>
+"Four minutes!" exclaimed Job. "That's queer, and they're the regular
+ten minute length. I wonder what this means.
+</P>
+
+<P>
+He took up another fuse, and examined it closely.
+</P>
+
+<P>
+"Why!" he cried. "These aren't our fuses at all. They're another make,
+and much more rapid in burning. No wonder you've been having premature
+blasts. They go off in about half the time they should."
+</P>
+
+<P>
+"I can't understhand thot!" said Tim, thoughtfully. "I keep all the
+fuses locked up, and only take thim out when I need thim."
+</P>
+
+<P>
+"Then somebody has been at your box, Tim, and they took out our regular
+fuses and put in these quicker ones. It's a game to make trouble for us
+among our men, and to damage the tunnel."
+</P>
+
+<P>
+"Bless my rubber boots!" cried Mr. Damon. "Who would do a thing like
+that?"
+</P>
+
+<P>
+"Our rivals, perhaps, though I do not like to accuse any man on such
+small evidence," said Walter. "But we must adopt new measures."
+</P>
+
+<P>
+"And be very careful of the fuses," said Job.
+</P>
+
+<P>
+"Thot's what I will!" declared Tim. "I'll put th' supply in a new
+place. No wonder there was blasts before th' min could git out th' way!
+Bad cess t' th' imps thot did this!" and he banged his big fist down on
+the table.
+</P>
+
+<P>
+Since the trouble began a guard had been always posted around the
+tunnel entrance and surrounding buildings, and this night the patrol
+was doubled. Tom, Mr. Damon and the two Titus brothers sat up quite
+late, talking over plans and ideas.
+</P>
+
+<P>
+Professor Bumper went to bed early, as he said he was going to set off
+before sunrise to make a search for the lost city.
+</P>
+
+<P>
+"I regard him as more or less of a visionary," said Mr. Job Titus; "but
+he seems a harmless gentleman, and we'll do all we can to help him."
+</P>
+
+<P>
+"Surely," agreed his brother.
+</P>
+
+<P>
+The night was not marked by any disturbance, and after breakfast, Tom,
+under the guidance of the Titus brothers, looked over the tunnel with a
+view to making his first experiment with the new explosive.
+</P>
+
+<P>
+The tunnel was being driven straight into the face of one of the
+smaller ranges of the Andes Mountains. It was to be four miles in
+length, and when it emerged on the other side it would enable trains to
+make connections between the two railroads, thus tapping a rich and
+fertile country.
+</P>
+
+<P>
+On the site of the tunnel, which was two days' mule travel east from
+Rimac, the Titus brothers had assembled their heavy machinery. They had
+brought some of their own men, including Tim Sullivan, with them, but
+the other labor was that of Peruvian Indians, with a native foreman,
+Serato, over them.
+</P>
+
+<P>
+There were engines, boilers, dynamos, motors, diamond drills, steam
+shovels and a miniature railway, with mules as the motive power. A
+small village had sprung up at the tunnel mouth, and there was a
+general store, besides many buildings for the sleeping and eating
+quarters of the laborers, as well as places where the white men could
+live. Their quarters were some distance from the native section.
+</P>
+
+<P>
+Powder, supplies, in fact everything save what game could be obtained
+in the forest, or what grains or fruits were brought in by natives
+living near by, had to be brought over the rough trail. But Titus
+Brothers had a large experience in engineering matters in wild and
+desolate countries, and they knew how to be as comfortable as possible.
+</P>
+
+<P>
+Mr. Damon learned that one of the districts whence his company had been
+in the habit of getting quinine was distant a day's journey over the
+mountain, so he decided to make the trip, with a native guide, and see
+if he could get at the bottom of the difficulty in forwarding shipments.
+</P>
+
+<P>
+This was a few days after the arrival of our friends. Meanwhile, Tom
+had been shown all through the tunnel by the Titus Brothers and had had
+his first sight of the hard cliff of rock which seemed to be a
+veritable stone wall in the way of progress&mdash;or at least such progress
+as was satisfactory to the contractors.
+</P>
+
+<P>
+"Well, we'll try what some of my explosive will do," said Tom, when he
+had finished the examination. "I don't claim it will be as successful
+as the sample blast we set off at Shopton, but we'll do our best."
+</P>
+
+<P>
+Holes were drilled in the face of the rock, and several charges of the
+new explosive tamped in. Wires were attached to the fuses, which were
+of a new kind, and warning was given to clear the tunnel. The wires ran
+out to the mouth of the horizontal shaft and Tom, holding the switch in
+his hand made ready to set off the blast.
+</P>
+
+<P>
+"Are they all out?" he asked Tim Sullivan, who had emerged, herding the
+Indian laborers before him. Tim insisted on being the last man to seek
+safety when an explosion was to take place.
+</P>
+
+<P>
+"All ready, sor," answered the foreman.
+</P>
+
+<P>
+"Here she goes!" cried Tom, as his fingers closed the circuit.

+Mysterious Disappearances
+</H3>
+
+<P>
+There was a dull, muffled report, a sort of rumbling that seemed to
+extend away down under the earth and then echo back again until the
+ground near the mouth of the tunnel, where the party was standing,
+appeared to rock and heave. There followed a cloud of yellow, heavy
+smoke which made one choke and gasp, and Tom, seeing it, cried:
+</P>
+
+<P>
+"Down! Down, everybody! There's a back draft, and if you breathe any of
+that powder vapor you'll have a fearful headache! Get down, until the
+smoke rises!"
+</P>
+
+<P>
+The tunnel contractors and their men understood the danger, for they
+had handled explosives before. It is a well-known fact that the fumes
+of dynamite and other giant powders will often produce severe
+headaches, and even illness. Tom's explosive contained a certain
+percentage of dynamite, and he knew its ill effects. Stretched prone,
+or crouching on the ground, there was little danger, as the fumes,
+being lighter than air, rose. The yellow haze soon drifted away, and it
+was safe to rise.
+</P>
+
+<P>
+"Well, I wonder how much rock your explosive tore loose for us, Tom,"
+observed Job Titus, as he looked at the thin, yellowish cloud of smoke
+that was still lazily drifting from the tunnel.
+</P>
+
+<P>
+"Can't tell until we go in and take a look," replied the young
+inventor. "It won't be safe to go in for a while yet, though. That
+smoke will hang in there a long time. I didn't think there'd be a back
+draft."
+</P>
+
+<P>
+"There is, for we've often had the same trouble with our shots," Walter
+Titus said. "I can't account for it unless there is some opening in the
+shaft, connecting with the outer air, which admits a wind that drives
+the smoke out of the mouth, instead of forward into the blast hole.
+It's a queer thing and we haven't been able to get at the bottom of it."
+</P>
+
+<P>
+"That's right," agreed his brother. "We've looked for some opening, or
+natural shaft, but haven't been able to find it. Sometimes we shoot
+off a charge and everything goes well, the smoke disappears in a few
+minutes. Again it will all blow out this way and we lose half a day
+waiting for the air to clear. There's a hidden shaft, or natural
+chimney, I'm sure, but we can't find it."
+</P>
+
+<P>
+"Thot blast didn't make much racket," commented Tim Sullivan. "I doubt
+thot much rock come down. An' thot's not sayin' anythin' ag'in yer
+powder, lad," he went on to Tom.
+</P>
+
+<P>
+"Oh, that's all right," Tom Swift replied, with a laugh. "My explosive
+doesn't work by sound. It has lots of power, but it doesn't produce
+much concussion."
+</P>
+
+<P>
+"We've often made more noise with our blasts," confirmed Job Titus,
+"but I can't say much for our results."
+</P>
+
+<P>
+They were all anxious, Tom included, to hurry into the tunnel to see
+how much rock had been loosened by the blast, but it was not safe to
+venture in until the fumes had been allowed to disperse. In about an
+hour, however, Tim Sullivan, venturing part way in, sniffed the air and
+called:
+</P>
+
+<P>
+"It's all right, byes! Air's clear. Now come on!"
+</P>
+
+<P>
+They all hurried eagerly into the shaft, Mr. Damon stumbling along at
+Tom's side, as anxious as the lad himself. Before they reached the face
+of the cliff against which the bore had been driven, and which was as a
+solid wall of rock to further progress, they began to tread on
+fragments of stone.
+</P>
+
+<P>
+"Well, it blew some as far back as here," said Walter Titus. "That's a
+good sign."
+</P>
+
+<P>
+"I hope so," Tom remarked.
+</P>
+
+<P>
+There were still some fumes noticeable in the tunnel, and Mr. Damon
+complained of a slight feeling of illness, while Koku, who kept at
+Tom's side, murmured that it made his eyes smart. But the sensations
+soon passed.
+</P>
+
+<P>
+They came to a stop as the face of the cliff loomed into view in the
+glare of a searchlight which Job Titus switched on. Then a murmur of
+wonder came from every one, save from Tom Swift. He, modestly, kept
+silent.
+</P>
+
+<P>
+"Bless my breakfast orange!" cried Mr. Damon. "What a big hole!"
+</P>
+
+<P>
+There was a great gash blown in the hard rock which had acted as a bar
+to the further progress of the tunnel. A great heap of rock, broken
+into small fragments, was on the floor of the shaft, and there was a
+big hole filled with debris which would have to be removed before the
+extent of the blast could be seen.
+</P>
+
+<P>
+"That's doing the work!" cried Job Titus.
+</P>
+
+<P>
+"It beats any two blasts we ever set off," declared his brother.
+</P>
+
+<P>
+"Much fine!" muttered the Peruvian foreman, Serato.
+</P>
+
+<P>
+"It's a lalapaloosa, lad! Thot's what it is!" enthusiastically
+exclaimed Tim Sullivan. "Now the black beggars will have some rock to
+shovel! Come on there, Serato, git yer lazy imps t' work cartin' this
+stuff away. We've got a man on th' job now in this new powder of Tom
+Swift's. Git busy!"
+</P>
+
+<P>
+"Um!" grunted the Indian, and he called to his men who were soon busy
+with picks and shovels, loading the loosened rock and earth into the
+mule-hauled dump cars which took it to the mouth of the tunnel, whence
+it was shunted off on another small railroad to fill in a big gulch to
+save bridging it.
+</P>
+
+<P>
+Tom's first blast was very successful, and enough rock was loosed to
+keep the laborers busy for a week. The contractors were more than
+satisfied.
+</P>
+
+<P>
+"At this rate we'll finish ahead of time, and earn a premium," said Job
+to his brother.
+</P>
+
+<P>
+"That's right. You didn't make any mistake in appealing to Tom Swift.
+But I wonder if Blakeson & Grinder have given up trying to get the job
+away from us?"
+</P>
+
+<P>
+"I don't know. I'd never trust them. We must watch out for Waddington.
+That bomb on the vessel had a funny look, even if it was not meant to
+kill Tom or me. I won't relax any."
+</P>
+
+<P>
+"No, I guess it wouldn't be safe."
+</P>
+
+<P>
+But a week went by without any manifestation having been made by the
+rival tunnel contractors. During that week more of Tom's explosive
+arrived, and he busied himself getting ready another blast which could
+be set off as soon as the debris from the first should have been
+cleared away.
+</P>
+
+<P>
+Meanwhile, Professor Bumper, with his Indian guides and helpers, had
+made several trips into the mountain regions about Rimac, but each time
+that he returned to the tunnel camp to renew his supplies, he had only
+a story of failure to recite.
+</P>
+
+<P>
+"But I am positive that somewhere in this vicinity is the lost Peruvian
+city of Pelone," he said. "Every indication points to this as the
+region, and the more I study the plates of gold, and read their
+message, the more I am convinced that this is the place spoken of.
+</P>
+
+<P>
+"But we have been over many mountains, and in more valleys, without
+finding a trace of the ancient civilization I feel sure once flourished
+here. There are no relics of a lost race&mdash;not so much as an arrow or
+spear head. But, somehow or other, I feel that I shall find the lost
+city. And when I do I shall be famous!"
+</P>
+
+<P>
+"Mr. Damon and I will help you all we can," Tom said. "As soon as I get
+ready the next blast I'll have a little time to myself, and we will go
+with you on a trip or two."
+</P>
+
+<P>
+"I shall be very glad to have you," the bald-headed scientist remarked.
+</P>
+
+<P>
+Tom's second blast was even more successful than the first, and enough
+of the hard rock was loosed and pulverized to give the Indian laborers
+ten days' work in removing it from the tunnel.
+</P>
+
+<P>
+Then, as the services of the young inventor would not be needed for a
+week or more, he decided to go on a little trip with Professor Bumper.
+</P>
+
+<P>
+"I'll come too," said Mr. Damon. "One of the sub-contractors whose men
+are gathering the cinchona bark for our firm has his headquarters in
+the region where you are going, and I can go over there and see why he
+isn't up to the mark."
+</P>
+
+<P>
+Accordingly, preparations having been made to spend a week in camp in
+the forests of the Andes, Tom and his party set off one morning.
+Professor Bumper's Indian helpers would do the hard work, and, of
+course, Koku, who went wherever Tom went, would be on hand in case some
+feat of strength were needed.
+</P>
+
+<P>
+It was a blind search, this hunt for a lost city, and as much luck
+might be expected going in one direction as in another; so the party
+had no fixed point toward which to travel. Only Mr. Damon stipulated
+that he wanted to reach a certain village, and they planned to include
+that on their route.
+</P>
+
+<P>
+Tom Swift took his electric rifle with him, and with it he was able to
+bring down a couple of deer which formed a welcome addition to the camp
+fare.
+</P>
+
+<P>
+The rifle was a source of great wonder to the Peruvians. They were
+familiar with ordinary firearms, and some of them possessed
+old-fashioned guns. But Tom's electric weapon, which made not a sound,
+but killed with the swiftness of light, was awesome to them. The
+interpreter accompanying Professor Bumper confided privately to Tom
+that the other Indians regarded the young inventor as a devil who
+could, if he wished, slay by the mere winking of an eye.
+</P>
+
+<P>
+Mr. Damon located the quinine-gathering force he was anxious to see,
+and, through the interpreter, told the chief that more bark must be
+brought in to keep up to the terms of the contract.
+</P>
+
+<P>
+But something seemed to be the matter. The Indian chief was indifferent
+to the interpreted demands of Mr. Damon, and that gentleman, though he
+blessed any number of animate and inanimate objects, seemed to make no
+impression.
+</P>
+
+<P>
+"No got men to gather bark, him say," translated the interpreter.
+</P>
+
+<P>
+"Hasn't got any men!" exclaimed Mr. Damon. "Why, look at all the lazy
+beggars around the village."
+</P>
+
+<P>
+This was true enough, for there were any number of able-bodied Indians
+lolling in the shade.
+</P>
+
+<P>
+"Him say him no got," repeated the translator, doggedly.
+</P>
+
+<P>
+At that moment screams arose back of one the grass huts, and a child
+ran out into the open, followed by a savage dog which was snapping at
+the little one's bare legs.
+</P>
+
+<P>
+"Bless my rat trap!" gasped Mr. Damon. "A mad dog!"
+</P>
+
+<P>
+Shouts and cries arose from among the Indians. Women screamed, and
+those who had children gathered them up in their arms to run to
+shelter. The men threw all sorts of missiles at the infuriated animal,
+but seemed afraid to approach it to knock it over with a club, or to go
+to the relief of the frightened child which was now only a few feet
+ahead of the animal, running in a circle.
+</P>
+
+<P>
+"Me git him!" cried Koku, jumping forward.
+</P>
+
+<P>
+"No, Wait!" exclaimed Tom Swift. "You can kill the dog all right,
+Koku," he said, "but a scratch from his tooth might be fatal. I'll fix
+him!"
+</P>
+
+<P>
+Snatching his electric rifle from the Indian bearer who carried it, Tom
+took quick aim. There was no flash, no report and no puff of smoke, but
+the dog suddenly crumpled up in a heap, and, with a dying yelp, rolled
+to one side. The child was saved.
+</P>
+
+<P>
+The little one, aware that something had happened, turned and saw the
+stretched out form of its enemy. Then, sobbing and crying, it ran
+toward its mother who had just heard the news.
+</P>
+
+<P>
+While the mothers gathered about the child, and while the older boys
+and girls made a ring at a respectful distance from the dog, there was
+activity noticed among the men of the village. They began hurrying out
+along the forest paths.
+</P>
+
+<P>
+"Where are they going?" asked Tom. "Is there some trouble? Was that a
+sacred dog, and did I get in bad by killing it?"
+</P>
+
+<P>
+The interpreter and the native chief conversed rapidly for a moment and
+then the former, turning to Tom, said:
+</P>
+
+<P>
+"Men go git cinchona bark now. Plenty get for him," and he pointed to
+Mr. Damon. "They no like stay in village. T'ink yo' got lightning in
+yo' pocket," and he pointed to the electric rifle.
+</P>
+
+<P>
+"Oh, I see!" laughed Tom. "They think I'm a sort of wizard. Well, so I
+am. Tell them if they don't get lots of quinine bark I'll have to stay
+here until all the mad dogs are shot."
+</P>
+
+<P>
+The interpreter translated, and when the chief had ceased replying, Tom
+and the others were told:
+</P>
+
+<P>
+"Plenty bark git. Plenty much. Yo' go away with yo' lightning. All
+right now."
+</P>
+
+<P>
+"Well, it's a good thing I keeled over that dog," Tom said. "It was the
+best object lesson I could give them."
+</P>
+
+<P>
+And from then on there was no more trouble in this district about
+getting a supply of the medicinal bark.
+</P>
+
+<P>
+A week passed and Professor Bumper was no nearer finding the lost city
+than he had been at first. Reluctantly, he returned to the tunnel camp
+to get more provisions.
+</P>
+
+<P>
+"And then I'll start out again," he said.
+</P>
+
+<P>
+"We'll go with you some other time," promised Tom. "But now I expect
+I'll have to get another blast ready."
+</P>
+
+<P>
+He found the debris brought down by the second one all removed, and in
+a few days, preparations for exploding more of the powder were under
+way.
+</P>
+
+<P>
+Many holes had been drilled in the face of the cliff of hard rock, and
+the charges tamped in. Electric wires connected them, and they were run
+out to the tunnel mouth where the switch was located.
+</P>
+
+<P>
+This was done late one afternoon, and it was planned to set off the
+blast at the close of the working day, to allow all night for the fumes
+to be blown away by the current of air in the tunnel.
+</P>
+
+<P>
+"Get the men out, Tim," said Tom, when all was ready.
+</P>
+
+<P>
+"All right, sor," was the answer, and the Irish foreman went back
+toward the far end of the bore to tell the last shift of laborers to
+come out so the blast could be set off.
+</P>
+
+<P>
+But in a little while Tim came running back with a queer look on his
+face.
+</P>
+
+<P>
+"What's the matter?" asked Tom. "Why didn't you bring the men with you?"
+</P>
+
+<P>
+"Because, sor, they're not there!"
+</P>
+
+<P>
+"Not in the tunnel? Why, they were working there a little while ago,
+when I made the last connection!"
+</P>
+
+<P>
+"I know they were, but they've disappeared."
+</P>
+
+<P>
+"Disappeared?"
+</P>
+
+<P>
+"Yis sir. There's no way out except at this end an' you didn't see thim
+come out: did you?"
+</P>
+
+<P>
+"Then they've disappeared! That's all there is to it! Bad goin's on,
+thot's what it is, sor! Bad!" and Tim shook his head mournfully.

+
+<P>
+"There must be some mistake," said Tom, wondering if the Irish foreman
+were given to joking. Yet he did not seem that kind of man.
+</P>
+
+<P>
+"Mistake? How can there be a mistake, sor? I wint in there to tell th'
+black imps t' come out, but they're not there to tell!"
+</P>
+
+<P>
+"What's the trouble?" asked Job Titus, coming out of the office near
+the tunnel mouth. "What's wrong, Tom?"
+</P>
+
+<P>
+"Why, I sent Tim in to tell the men to come out, as I was going to set
+off a blast, but he says the men aren't in there. And I'm sure the last
+shift hasn't come out."
+</P>
+
+<P>
+By this time Koku, Mr. Damon and Walter Titus had come up to find out
+what the trouble was.
+</P>
+
+<P>
+"The min have disappeared&mdash;that's all there is to it!" Tim said.
+</P>
+
+<P>
+"Perhaps they have missed their way&mdash;the lights may have gone out, and
+they might have wandered into some abandoned cutting," suggested Tom.
+</P>
+
+<P>
+"There aren't any abandoned cuttin's," declared Tim. "It's a straight
+bore, not a shaft of any kind. I've looked everywhere, and th' min
+aren't there I tell ye!"
+</P>
+
+<P>
+"Are the lights going?" asked Job. "You might have missed them in the
+dark, Tim."
+</P>
+
+<P>
+"The lights are going all right, Mr. Titus," said the young man in
+charge of the electrical arrangements. "The dynamo hasn't been stopped
+to-day."
+</P>
+
+<P>
+"Come on, we'll have a look," proposed Walter Titus. "There must be
+some mistake. Hold back the blast, Tom."
+</P>
+
+<P>
+"All right," and the young inventor disconnected the electrical
+detonating switch. "I'll come along and have a look too," he added.
+"Don't let anybody meddle with the wires, Jack," he said to the young
+Englishman who was in charge of the dynamo.
+</P>
+
+<P>
+Into the dimly-lit tunnel advanced the party of investigators, with Tim
+Sullivan in the lead.
+</P>
+
+<P>
+"Not a man could I find!" he said, murmuring to himself. "Not a man!
+An' I mind th' time in Oireland whin th' little people made vanish a
+whole village like this, jist bekase ould Mike Maguire uprooted a bed
+of shamrocks."
+</P>
+
+<P>
+"That's enough of your superstitions, Tim," warned Job Titus. "If some
+of the other Indians hear you go on this way they'll desert as they did
+once before."
+</P>
+
+<P>
+"Did they do that?" asked Tom.
+</P>
+
+<P>
+"Yes, we had trouble that way when we first began the work. The place
+here was a howling wilderness then, and there were lots of pumas around.
+</P>
+
+<P>
+"A puma is a small sized lion, you know, not specially dangerous unless
+cornered. Well, some of the men had their families here with them, and
+a couple of children disappeared. The story got started that there was
+a big puma&mdash;the king of them all&mdash;carrying off the little ones, and my
+brother and I awoke one morning to find every laborer missing. They
+departed bag and baggage. Afraid of the pumas."
+</P>
+
+<P>
+"What did you do?"
+</P>
+
+<P>
+"Well, we organized ourselves and our white helpers into a hunting
+party and killed a lot of the beasts. There wasn't any big one though."
+</P>
+
+<P>
+"And what had become of the children?"
+</P>
+
+<P>
+"They weren't eaten at all. They had wandered off into the woods, and
+some natives found them and took care of them. Eventually, they got
+back home. But it was a long while before we could persuade the Indians
+to come back. Since then we haven't had any trouble, and I don't want
+Tim, with his superstitious fancies, to start any."
+</P>
+
+<P>
+"But the min are gone!" insisted the Irish foreman, who had listened to
+this story as he and the others walked along.
+</P>
+
+<P>
+"We'll find them," declared Mr. Titus.
+</P>
+
+<P>
+But though they looked all along the big shaft, and though the place
+was well lighted by extra lamps that were turned on when the
+investigation started, no trace could be found of the workmen, who had
+been left in the tunnel to finish tamping the blast charges. The party
+reached the rocky heading, in the face of which the powerful explosive
+had been placed, and not an Indian was in sight. Nor, as far as could
+be told, was there any side niche, or blind shaft, in which they could
+be hiding.
+</P>
+
+<P>
+Sometimes, when small blasts were set off, the men would go behind a
+projecting shoulder of rock to wait until the charge had been fired,
+but now none was in such a refuge.
+</P>
+
+<P>
+"It is queer," admitted Walter Titus. "Where can the men have gone?"
+</P>
+
+<P>
+"That's what I want to know!" exclaimed Tim.
+</P>
+
+<P>
+"Are you sure they didn't come out the mouth of the tunnel?" asked Job
+Titus.
+</P>
+
+<P>
+"Positive," asserted Tom. I was there all the while, rigging up the
+fires."
+</P>
+
+<P>
+"We'll call the roll, and check up," decided Job Titus. "Get Serato to
+help."
+</P>
+
+<P>
+The Indian foreman had not been in the tunnel with the last shift of
+men, having left them to Tim Sullivan to get out in time. The Indian
+foreman was called from his supper in the shack where he had his
+headquarters, and the roll of workmen was called.
+</P>
+
+<P>
+Ten men were missing, and when this fact became known there were uneasy
+looks among the others.
+</P>
+
+<P>
+"Well," said Mr. Titus, after a pause. "The men are either in the
+tunnel or out of it. If they're in we don't dare set off the blast, and
+if they're out they'll show up, sooner or later, for supper. I never
+knew any of 'em to miss a meal."
+</P>
+
+<P>
+"If such a thing were possible," said Walter Titus, "I would say that
+our rivals had a hand in this, and had induced our men to bolt in order
+to cripple our force. But we haven't seen any of Blakeson & Grinder's
+emissaries about, and, if they were, how could they get the ten men out
+of the tunnel without our seeing them? It's impossible!"
+</P>
+
+<P>
+"Well, what did happen then?" asked Tom.
+</P>
+
+<P>
+"I'm inclined to think that the men came out and neither you, nor any
+one else, saw them. They ran away for reasons of their own. We'll take
+another look in the morning, and then set off the blast."
+</P>
+
+<P>
+And this was done. There being no trace of the men in the tunnel it was
+deemed safe to explode the charges. This was done, a great amount of
+rock being loosened.
+</P>
+
+<P>
+The laborers hung back when the orders were given to go in and clean
+up. There were mutterings among them.
+</P>
+
+<P>
+"What's the matter?" asked Job Titus.
+</P>
+
+<P>
+"Them afraid," answered Serato. "Them say devil in tunnel eat um up! No
+go in."
+</P>
+
+<P>
+"They won't go in, eh?" cried Tim Sullivan. "Well, they will thot! If
+there's a divil inside there's a worse one outside, an' thot's me! Git
+in there now, ye black-livered spalapeens!" and catching up a big club
+the Irishman made a rush for the hesitating laborers. With a howl they
+rushed into the tunnel, and were soon loading rock into the dump cars.

+On the Watch
+</H3>
+
+<P>
+The mystery of the disappearance of the ten men&mdash;for mystery it
+was&mdash;remained, and as no side opening or passage could be found within
+the tunnel, it came to be the generally accepted explanation that the
+laborers had come out unobserved, and, for reasons of their own, had
+run away.
+</P>
+
+<P>
+This habit on the part of the Peruvian workers was not unusual. In
+fact, the Titus brothers had to maintain a sort of permanent employment
+agency in Lima to replace the deserters. But they were used to this.
+The difference was that the Indians used to vanish from camp at night,
+and invariably after pay-day.
+</P>
+
+<P>
+"And that's the only reason I have a slight doubt that they walked out
+of the tunnel," said Job Titus. "There was money due em."
+</P>
+
+<P>
+"They never came out of the front entrance of the tunnel," said Tom.
+"Of that I'm positive."
+</P>
+
+<P>
+But there was no way of proving his assertion.
+</P>
+
+<P>
+The third blast, while not as successful as the second in the amount of
+rock loosened, was better than the first, and made a big advance in the
+tunnel progress. Tom was beginning to understand the nature of the
+mountain into which the big shaft was being driven and he learned how
+better to apply the force of his explosive.
+</P>
+
+<P>
+That was the work which he had charge of&mdash;the placing of the giant
+powder so it would do the most effective work. Then, when the fumes
+from the blast had cleared away, in would surge the workmen to clear
+away the debris.
+</P>
+
+<P>
+Under the direction of Mr. Swift, left at Shopton to oversee the
+manufacture of the explosive, new shipments came on promptly to Lima,
+and were brought out to the tunnel on the backs of mules, or in the
+case of small quantities, on the llamas. But the latter brutes will not
+carry a heavy load, lying down and refusing to get up if they are
+overburdened, whereas one has yet to find a mule's limit.
+</P>
+
+<P>
+After his first success in getting the natives to take a more active
+interest in the gathering of the cinchona bark, Mr. Damon found it
+rather easy, for the story of Tom's electric rifle and how it had
+killed the mad dog spread among the tribes, and Mr. Damon had but to
+announce that the "lightning shooter," as Tom was called, was a friend
+of the drug concern to bring about the desired results. Mr. Damon, by
+paying a sort of bribe, disguised under the name "tax," secured the
+help of Peruvian officials so he had no trouble on that score.
+</P>
+
+<P>
+Koku was in his element. He liked a wild life and Peru was much more
+like the country of giants where Tom had found him, than any place the
+big man had since visited. Koku had great strength and wanted to use
+it, and after a week or so of idleness he persuaded Tom to let him go
+in the tunnel to work.
+</P>
+
+<P>
+The giant was made a sort of foreman under Tim, and the two became
+great friends. The only trouble with Koku was that he would do a thing
+himself instead of letting his men do it, as, of course, all proper
+foremen should do. If the giant saw two or three of the Indians trying
+to lift a big rock into the little dump cars, and failing because of
+its great weight, he would good-naturedly thrust them aside, pick up
+the big stone in his mighty arms, and deposit it in its place.
+</P>
+
+<P>
+And once when an unusually big load had been put in a car, and the mule
+attached found it impossible to pull it out to the tunnel mouth, Koku
+unhitched the creature and, slipping the harness around his waist,
+walked out, dragging the load as easily as if pulling a child on a sled.
+</P>
+
+<P>
+Professor Bumper kept on with his search for the lost city of Pelone.
+Back and forth he wandered among the wild Andes Mountains, now hopeful
+that he was on the right trail, and again in despair. Tom and Mr. Damon
+went with him once more for a week, and though they enjoyed the trip,
+for the professor was a delightful companion, there were no results.
+But the scientist would not give up.
+</P>
+
+<P>
+Tom Swift was kept busy looking after the shipments of the explosive,
+and arranging for the blasts. He had letters from Ned Newton in which
+news of Shopton was given, and Mr. Swift wrote occasionally. But the
+mails in the wilderness of the Andes were few and far between.
+</P>
+
+<P>
+Tom wrote a letter of explanation to Mr. Nestor, in addition to the
+wireless he had sent regarding the box labeled dynamite, but he got no
+answer. Nor were his letters to Mary answered.
+</P>
+
+<P>
+"I wonder what's wrong?" Tom mused. "It can't be that they think I did
+that on purpose. And even if Mr. Nestor is angry at me for something
+that wasn't my fault, Mary ought to write."
+</P>
+
+<P>
+But she did not, and Tom grew a bit despondent as the days went by and
+no word came.
+</P>
+
+<P>
+"I suppose they might be offended because I left Rad to do up that
+package instead of attending to it myself," thought Tom. "Well, I did
+make a mistake there, but I didn't mean to. I never thought about
+Eradicate's not reading. I'll make him go to night school as soon as I
+get back. But maybe I'll never get another chance to send Mary
+anything. If I do, I'll not let Rad deliver it&mdash;that's sure."
+</P>
+
+<P>
+The feeling of alarm engendered among the Indians by the disappearance
+of their ten fellow-workers seemed to have disappeared. There were
+rumors that some of the mysterious ten had been seen in distant
+villages and settlements, but the Titus brothers could not confirm this.
+</P>
+
+<P>
+"I don't think anything serious happened to them, anyhow," said Job
+Titus one day. "And I should hate to think our work was responsible for
+harm to any one."
+</P>
+
+<P>
+"Your rivals don't seem to be doing much to hamper you," observed Tom.
+"I guess Waddington gave up.
+</P>
+
+<P>
+"I won't be too sure of that," said Mr. Titus.
+</P>
+
+<P>
+"Why, what has happened?" Tom asked.
+</P>
+
+<P>
+"Well, nothing down here&mdash;that is, directly&mdash;but we are meeting with
+trouble on the financial end. The Peruvian government is holding back
+payments."
+</P>
+
+<P>
+"Why is that?"
+</P>
+
+<P>
+"They claim we are not as far advanced as we ought to be."
+</P>
+
+<P>
+"Aren't you?"
+</P>
+
+<P>
+"Practically, yes. There was no set limit of work to be done for the
+intermediate payments. We bonded ourselves to have the tunnel done at a
+certain date.
+</P>
+
+<P>
+"If we fail, we lose a large sum, and if we get it done ahead of time
+we get a big premium. There was no question as to completing a certain
+amount of footage before we received certain payments. But Senor
+Belasdo, the government representative, claims that we will not be done
+in time, and therefore he is holding back money due us. I'm sure the
+rival contractors have set him up to this, because he was always decent
+to us before.
+</P>
+
+<P>
+"Another matter, too, makes me suspicious. We have tried to raise money
+in New York to tide us over while the government is holding up our
+funds here. But our New York office is meeting with difficulties. They
+report there is a story current to the effect that we are going to
+fail, and while that isn't so, you know how hard it is to borrow money
+in the face of such rumors. We are doing all we can to fight them, of
+course, and maybe we'll beat out our rivals yet.
+</P>
+
+<P>
+"But that isn't all. I'm sure some one is on the ground here trying to
+make trouble among our workers. I never knew so many men to leave, one
+after another. It's keeping the employment agency in Lima busy
+supplying us with new workers. And so many of them are unskilled. They
+aren't able to do half the work of the old men, and poor Tim Sullivan
+is in despair."
+</P>
+
+<P>
+"You think some one here is causing dissensions and desertions among
+your men?"
+</P>
+
+<P>
+"I'm sure of it! I've tried to ferret out who it is, but the spy, for
+such he must be, keeps his identity well hidden."
+</P>
+
+<P>
+Tom thought for a moment. Then he said:
+</P>
+
+<P>
+"Mr. Titus, with your permission, I'll see if I can find out about this
+for you."
+</P>
+
+<P>
+"Find out what, Tom?"
+</P>
+
+<P>
+"What is causing the men to leave. I don't believe it's the scare about
+the ten missing ones."
+</P>
+
+<P>
+"Nor do I. That's past and gone. But how are you going to get at the
+bottom of it?"
+</P>
+
+<P>
+"By keeping watch. I've got nothing to do now for the next week. We've
+just set off a big blast, and I've got the powder for the following one
+all ready. The men will be busy for some time getting out the broken
+rock. Now what I propose to do is to go in the tunnel and work among
+them until I can learn something.
+</P>
+
+<P>
+"I can understand the language pretty well now, though I can't speak
+much of it. I'll go in the tunnel every day and find out what's going
+on."
+</P>
+
+<P>
+"But you'll be known, and if one of our men, or one who we suppose is
+one, turns out to be a spy, he'll be very cautious while you're in
+there."
+</P>
+
+<P>
+"He won't know me," Tom said. "This is how I'll work it. I'll go off
+with Professor Bumper the next time he starts on one of his weekly
+expeditions into the woods. But I won't go far until I turn around and
+come back. I'll adopt some sort of disguise, and I'll apply to you for
+work. You can tell Tim to put me on. You might let him into the secret,
+but no one else."
+</P>
+
+<P>
+A few days later Tom was seen departing with Professor Bumper into the
+interior, presumably to help look for the lost city. Mr. Damon was away
+from camp on business connected with the drug concern, and Koku, to his
+delight, had been given charge of a stationary hoisting engine outside
+the tunnel, so he would not come in contact with Tom. It was not
+thought wise to take the giant into the secret.
+</P>
+
+<P>
+Then one day, shortly after Professor Bumper and Tom had disappeared
+into the forest, a ragged and unkempt white man applied at the tunnel
+camp for work. There was just the barest wink as he accosted Mr. Titus,
+who winked in turn, and then the new man was handed over to Tim
+Sullivan, as a sort of helper.
+</P>
+
+<P>
+And so Tom Swift began his watch.

+</H3>
+
+<P>
+Left to himself, with only the rather silent gang of Peruvian Indians
+as company, Tom Swift looked about him. There was not much active work
+to be done, only to see that the Indians filled the dump cars evenly
+full, so none of the broken rock would spill over the side and litter
+the tramway. Then, too, he had to keep the Indians up to the mark
+working, for these men were no different from any other, and they were
+just as inclined to "loaf on the job" when the eye of the "boss" was
+turned away.
+</P>
+
+<P>
+They did not talk much, murmuring among themselves now and then, and
+little of what they said was intelligible to Tom. But he knew enough
+of the language to give them orders, the main one of which was:
+</P>
+
+<P>
+"Hurry up!"
+</P>
+
+<P>
+Now, having seen to it that the gang of which he was in temporary
+charge was busily engaged, Tom had a chance to look about him. The
+tunnel was not new to him. Much of his time in the past month had been
+spent in its black depths, illuminated, more or less, by the string of
+incandescent lights.
+</P>
+
+<P>
+"What I want to find," mused Tom, as he walked to and fro, "is the
+place where those Indians disappeared. For I'm positive they got away
+through some hole in this tunnel. They never came out the main
+entrance."
+</P>
+
+<P>
+Tom held to this view in spite of the fact that nearly every one else
+believed the contrary&mdash;that the men had left by the tunnel mouth, near
+which Tom happened to be alone at the time.
+</P>
+
+<P>
+Now, left to himself, with merely nominal duties, and so disguised that
+none of the workmen would know him for the trim young inventor who
+oversaw the preparing of the blast charges, Tom Swift walked to and
+fro, looking for some carefully hidden passage or shaft by means of
+which the men had got away.
+</P>
+
+<P>
+"For it must be well hidden to have escaped observation so long," Tom
+decided. "And it must be a natural shaft, or hole, for we are boring
+into native rock, and it isn't likely that these Indians ever tried to
+make a tunnel here. There must be some natural fissure communicating
+with the outside of the mountain, in a place where no one would see the
+men coming out."
+</P>
+
+<P>
+But though Tom believed this it was another matter to demonstrate his
+belief. In the intervals of seeing that the natives properly loaded the
+dump cars, and removed as much of the debris as possible, Tom looked
+carefully along the walls and roof of the tunnel thus far excavated.
+</P>
+
+<P>
+There were cracks and fissures, it is true, but they were all
+superficial ones, as Tom ascertained by poking a long pole up into them.
+</P>
+
+<P>
+"No getting out that way," he said, as he met with failure after
+failure.
+</P>
+
+<P>
+Once, while thus engaged, he saw Serato, the Indian foreman looking
+narrowly at him, and Serato said something in his own language which
+Tom could not understand. But just then along came Tim Sullivan, who,
+grasping the situation, exclaimed:
+</P>
+
+<P>
+"Thot's all roight, now, Serri, me lad!" for thus he contracted the
+Indian's name. "Thot's a new helper I have, a broth of a bye, an' yez
+kin kape yer hands off him. He's takin' orders from me!"
+</P>
+
+<P>
+"Um!" grunted the Indian. "Wha for he fish in tunnel roof?" for Tom's
+pole was one like those the Indians used when, on off days, they
+emulated Izaak Walton.
+</P>
+
+<P>
+"Fishin' is it!" exclaimed Tim. "Begorra 'tis flyin' fish he's after
+I'm thinkin'. Lave him alone though, Serri! I'm his boss!"
+</P>
+
+<P>
+"Um!" grunted the Indian again, as he moved off into the farther
+darkness.
+</P>
+
+<P>
+"Be careful, Tom," whispered the Irishman, when the native had gone.
+"These black imps is mighty suspicious. Maybe thot fellah had a hand in
+th' disappearances hisself."
+</P>
+
+<P>
+"Maybe," admitted Tom. "He may get a percentage on all new hands that
+are hired."
+</P>
+
+<P>
+Tom kept on with his search, always hoping he might find some hidden
+means of getting out of the tunnel. But as the days went by, and he
+discovered nothing, he began to despair.
+</P>
+
+<P>
+"The queer thing about it," mused Tom, "is what has become of the ten
+men. Even if they did find some secret means of leaving, what has
+become of them? They couldn't completely disappear, and they have
+families and relatives that would make some sort of fuss if they were
+out of sight completely this long. I wonder if any inquiries have been
+made about them?"
+</P>
+
+<P>
+When Tom came off duty he asked the Titus brothers whether or not any
+of the relatives of the missing men had come to seek news about them.
+None had.
+</P>
+
+<P>
+"Then," said Tom, "you can depend on it the men are all right, and
+their relatives know it. I wonder how it would do to make inquiries at
+that end? Question some of the relatives."
+</P>
+
+<P>
+"Bless my hat band!" exclaimed Mr. Damon, who was at the conference. "I
+never thought of that. I'll do it for you."
+</P>
+
+<P>
+The odd man had gotten his quinine gathering business well under way
+now, and he had some spare time. So, with an interpreter who could be
+trusted, he went to the native village whence had come nearly all of
+the ten missing men. But though Mr. Damon found some of their
+relatives, the latter, with shrugs of their shoulders, declared they
+had seen nothing of the ones sought.
+</P>
+
+<P>
+"And they didn't seem to worry much, either," reported Mr. Damon.
+</P>
+
+<P>
+"Then we can depend on it," remarked Tom, "that the men are all right
+and their relatives know it. There's some conspiracy here."
+</P>
+
+<P>
+So it seemed. But who was at the bottom of it?
+</P>
+
+<P>
+"I can't figure out where Blakeson & Grinder come in," said Job Titus.
+"They would have an object in crippling us, but they seem to be working
+from the financial end, trying to make us fail there. I haven't seen
+any of their sneaking agents around here lately, and as for Waddington
+he seems to have stayed up North."
+</P>
+
+<P>
+Tom resumed his vigil in the tunnel, poking here and there, but with
+little success. His week was about up, and he would soon have to resume
+his character as powder expert, for the debris was nearly all cleaned
+up, and another blast would have to be fired shortly.
+</P>
+
+<P>
+"Well, I'm stumped!" Tom admitted, the day when he was to come on duty
+for the last time as a pretended foreman. "I've hunted all over, and I
+can't find any secret passage."
+</P>
+
+<P>
+It was warm in the tunnel, and Tom, having seen one train of the dump
+cars loaded, sat down to rest on an elevated ledge of rock, where he
+had made a sort of easy chair for himself, with empty cement bags for
+cushions.
+</P>
+
+<P>
+The heat, his weariness and the monotonous clank-clank of a water pump
+near by, and the equally monotonous thump of the lumps of rocks in the
+cars made Tom drowsy. Almost before he knew it he was asleep.
+</P>
+
+<P>
+What suddenly awakened him he could not tell. Perhaps it was some
+influence on the brain cells, as when a vivid dream causes us to start
+up from slumber, or it may have been a voice. For certainly Tom heard a
+voice, he declared afterward.
+</P>
+
+<P>
+As he roused up he found himself staring at the rocky wall of the
+tunnel. And yet the wall seemed to have an opening in it and in the
+opening, as if it were in the frame of a picture, appeared the face Tom
+had seen at his library the day Job Titus called on him&mdash;the face of
+Waddington!
+</P>
+
+<P>
+Tom sat up so quickly that he hit his head sharply on a projecting rock
+spur, and, for the moment he "saw stars." And with the appearance of
+these twinkling points of light the face of Waddington seemed to fade
+away, as might a vision in a dream.
+</P>
+
+<P>
+"Bless my salt mackerel, as Mr. Damon would say!" cried Tom. "What have
+I discovered?"
+</P>
+
+<P>
+He rubbed his head where he had struck it, and then passed his hand
+before his eyes, to make sure he was awake. But the vision, if vision
+it was, had vanished, and he saw only the bare rock wall. However, the
+echo of the voice remained in his ears, and, looking down toward the
+tunnel floor Tom saw Serato, the Indian foreman.
+</P>
+
+<P>
+"Were you speaking to me?" asked Tom, for the man understood and spoke
+English fairly well.
+</P>
+
+<P>
+"No, sar. I not know you there!" and the foreman seemed startled at
+seeing Tom. Clearly he was in a fright.
+</P>
+
+<P>
+"You were speaking!" insisted Tom.
+</P>
+
+<P>
+"No, sar!" The man shook his head.
+</P>
+
+<P>
+"To some one up there!" went on the young inventor, waving his hand
+toward the spot where he had seen the face in the rock.
+</P>
+
+<P>
+"Me speak to roof? No, sar!" Serato laughed.
+</P>
+
+<P>
+Tom did not know what to believe.
+</P>
+
+<P>
+"You hear me tell um lazy man to much hurry," the Indian went on. "Me
+not know you sleep there, sar!"
+</P>
+
+<P>
+"Oh, all right," Tom said, recollecting that he must keep up his
+disguise. "Maybe I was dreaming."
+</P>
+
+<P>
+"Yes, sar," and the foreman hurried on, with a backward glance over his
+shoulder.
+</P>
+
+<P>
+"Now was I dreaming or not?" thought Tom. "I'm going to have a look at
+that place though, where I saw Waddington's face. Or did I imagine it?"
+</P>
+
+<P>
+He got a long pole and a powerful flash lamp, and when he had a chance,
+unobserved, he poked around in the vicinity where he had seen the face.
+</P>
+
+<P>
+But there was only solid rock.
+</P>
+
+<P>
+"It must have been a dream," Tom concluded. "I've been thinking too
+much about this business. I'll have to give up. I can't solve the
+mystery of the missing men."
+</P>
+
+<P>
+The next day, much disappointed, he resumed his own character as
+explosive expert, and prepared for another blast. The net result of his
+watch was that he became suspicious of Serato, and so informed the
+Titus Brothers.
+</P>
+
+<P>
+"Oh, but you're mistaken," said Job. "We have had him for years, on
+other contracts in Peru, and we trust him."
+</P>
+
+<P>
+"Well, I don't," Tom said, but he had to let it go at that.
+</P>
+
+<P>
+Another blast was set off, but it was not very successful.
+</P>
+
+<P>
+"The rock seems to be getting harder the farther in we go," commented
+Walter Titus. "We're not up to where we ought to be."
+</P>
+
+<P>
+"I'll have to look into it," answered Tom. "I may have to change the
+powder mixture. Guess I'll go up the mountain a way, and see if there
+are any outcroppings of rock there that would give me an idea of what
+lies underneath."
+</P>
+
+<P>
+Accordingly, while the men in the tunnel were clearing away the rock
+loosened by the blast, Tom, one day, taking his electric rifle with
+him, went up the mountain under which the big bore ran.
+</P>
+
+<P>
+He located, by computation, the spot beneath which the end of the
+tunnel then was, and began collecting samples of the outcropping ledge.
+He wanted to analyze these pieces of stone later. Koku was with him,
+and, giving the giant a bag of stones to carry, Tom walked on rather
+idly.
+</P>
+
+<P>
+It was a wild and desolate region in which he found himself on the side
+of the mountain. Beyond him stretched towering and snow-clad peaks, and
+high in the air were small specks, which he knew to be condors,
+watching with their eager eyes for their offal food.
+</P>
+
+<P>
+As Tom and Koku made their way along the mountain trail they came
+unexpectedly upon an Indian workman who was gathering herbs and bark,
+an industry by which many of the natives added to their scanty
+livelihood. The woman was familiar with the appearance of the white
+men, and nodded in friendly fashion.
+</P>
+
+<P>
+Tom passed on, thinking of many things, when he was suddenly startled
+by a scream from the woman. It was a scream of such terror and agony
+that, for the moment, Tom was stunned into inactivity. Then, as he
+turned, he saw a great condor sweeping down out of the air, the wind
+fairly whistling through the big, outstretched wings.
+</P>
+
+<P>
+"Jove!" ejaculated Tom. "Can the bird be going to attack the woman?"
+</P>
+
+<P>
+But this was not the object of the condor. It was aiming to strike,
+with its fierce talons, at a point some paces distant from where the
+woman stood, and in the intervals between her screams Tom heard her
+cry, in her native tongue:
+</P>
+
+<P>
+"My baby! My baby! The beast-bird will carry off my baby!"
+</P>
+
+<P>
+Then Tom understood. The woman herb-gatherer had brought her infant
+with her on her quest, and had laid it down on a bed of soft grass
+while she worked. And it was this infant, wrapped as Tom afterward saw
+in a piece of deer-skin, at which the condor was aiming.
+</P>
+
+<P>
+"Master shoot!" cried Koku, pointing to the down-sweeping bird.
+</P>
+
+<P>
+"You bet I'll shoot!" cried Tom.
+</P>
+
+<P>
+Throwing his electric rifle to his shoulder, Tom pressed the switch
+trigger. The unseen but powerful force shot straight at the condor.
+</P>
+
+<P>
+The outstretched wings fell limp, the great body seemed to shrivel up,
+and, with a crash, the bird fell into the underbrush, breaking the
+twigs and branches with its weight. The electric rifle, a full account
+of which was given in the volume entitled "Tom Swift and His Electric
+Rifle," had done its work well.
+</P>
+
+<P>
+With a scream, in which was mingled a cry of thanks, the woman threw
+herself on the sleeping child. The condor had fallen dead not three
+paces from it.
+</P>
+
+<P>
+Tom Swift had shot just in time.

+</H3>
+
+<P>
+Snatching up in her arms the now awakened child, the woman gazed for a
+moment into its face, which she covered with kisses. Then the
+herb-gatherer looked over to the dead, limp body of the great condor,
+and from thence to Tom.
+</P>
+
+<P>
+In another moment the woman had rushed forward, and knelt at the feet
+of the young inventor. Holding the baby in one arm, in her other hand
+the woman seized Tom's and kissed it fervently, at the same time pouring
+forth a torrent of impassioned language, of which Tom could only make
+out a word now and then. But he gathered that the woman was thanking
+him for having saved the child.
+</P>
+
+<P>
+"Oh, that's all right," Tom said, rather embarrassed by the
+hand-kissing. "It was an easy shot."
+</P>
+
+<P>
+An Indian came bursting through the bushes, evidently the woman's
+husband by the manner in which she greeted him, and Tom recognized the
+newcomer as one of the tunnel workers. There was some quick
+conversation between the husband and wife, in which the latter made all
+sorts of motions, including in their scope Tom, his rifle, the dead
+condor and the now smiling baby.
+</P>
+
+<P>
+The man took off his hat and approached Tom, genuflecting as he might
+have done in church.
+</P>
+
+<P>
+"She say you save baby from condor," the man said in his halting
+English. "She t'ank you&mdash;me, I t'ank you. Bird see babe in deer
+skin&mdash;t'ink um dead animal. Maybe so bird carry baby off, drop um on
+sharp stone, baby smile no more. You have our lives, senor! We do
+anyt'ing we can for you."
+</P>
+
+<P>
+"Thanks," said Tom, easily. "I'm glad I happened to be around. I
+supposed condors only went for things dead, but I reckon, as you say,
+it mistook the baby in the deer skin for a dead animal. And I guess it
+might have carried your little one off, or at least lifted it up, and
+then it might have dropped it far enough to have killed it. It sure is
+a big bird," and Tom strolled over to look at what he had bagged.
+</P>
+
+<P>
+The condor of the Andes is the largest bird of prey in existence. One
+in the Bronx Zoo, in New York, with his wings spread out, measured a
+little short of ten feet from tip to tip. Measure ten feet out on the
+ground and then imagine a bird with that wing stretch.
+</P>
+
+<P>
+This same condor in the park was made angry by a boy throwing a feather
+boa up into the air outside the cage. The condor raised himself from
+the ground, and hurled himself against the heavy wire netting so that
+the whole, big cage shook. And the breeze caused by the flapping wings
+blew off the hats of several spectators. So powerful was the air force
+from the condor's wings that it reminded one of the current caused when
+standing behind the propellers of an aeroplane in motion. The condor
+rarely attacks living persons or animals, though it has been known to
+carry off big sheep when driven by hunger.
+</P>
+
+<P>
+It was one of these animals Tom Swift had shot with his electric rifle.
+</P>
+
+<P>
+"We do anyt'ing you want," the man gratefully repeated.
+</P>
+
+<P>
+"Well, I've got about all I want," Tom said. "But if you could tell me
+where those ten missing men are, and how they got out of the tunnel,
+I'd be obliged to you."
+</P>
+
+<P>
+The woman did not seem to comprehend Tom's talk, but the man did. He
+started, and fear seemed to come over him.
+</P>
+
+<P>
+"Me&mdash;I&mdash;I can not tell," he murmured.
+</P>
+
+<P>
+"No, I don't suppose you can," said Tom, musingly. "Well, it doesn't
+matter, I guess I'll have to cross it off my books. I'll never find
+out."
+</P>
+
+<P>
+Again the Indian and his wife expressed their gratitude, and Tom, after
+letting the little brown baby cling to his finger, and patting its
+chubby cheek, went on his way with Koku.
+</P>
+
+<P>
+"Well, that was some excitement," mused Tom, who made little of the
+shot itself, for the condor was such a mark that he would have had to
+aim very badly indeed to miss it. And perhaps only the electric rifle
+could have killed quickly enough to prevent the baby's being injured in
+some way by the big bird, even though it was dying.
+</P>
+
+<P>
+"Master heap good shot!" exclaimed Koku, admiringly.
+</P>
+
+<P>
+The tunnel work went on, though not so well as when Tom's explosive was
+first used. The rock was indeed getting harder and was not so easily
+shattered. Tom made tests of the pieces he had obtained from the
+outcropping ledge on the mountain where he had shot the condor, and
+decided to make a change in the powder.
+</P>
+
+<P>
+Shipments were regularly received from Shopton, Mr. Swift keeping
+things in progress there. Mr. Damon's business was going on
+satisfactorily, and he lent what aid he could to Tom. As for Professor
+Bumper he kept on with his search for the lost city of Pelone, but with
+no success.
+</P>
+
+<P>
+The scientist wanted Tom and Mr. Damon to go on another trip with him,
+this time to a distant sierra, or fertile valley, where it was reported
+a race of Indians lived, different from others in that region.
+</P>
+
+<P>
+"It may be that they are descendants from the Pelonians," suggested the
+professor. Tom was too busy to go, but Mr. Damon went. The expedition
+had all sorts of trouble, losing its way and getting into a swamp from
+which escape was not easy. Then, too, the strange Indians proved
+hostile, and the professor and his party could not get nearer than the
+boundaries of the valley.
+</P>
+
+<P>
+"But the difficulties and the hostile attitude of these natives only
+makes me surer that I am on the right track," said Mr. Bumper. "I shall
+try again."
+</P>
+
+<P>
+Tom was busy over a problem in explosives one day when he saw Tim
+Sullivan hurrying into the office of the two brothers. The Irishman
+seemed excited.
+</P>
+
+<P>
+"I hope there hasn't been another premature blast," mused Tom. "But if
+there had been I think I'd have heard it."
+</P>
+
+<P>
+He hastened out to see Job and Walter Titus in excited conversation
+with Tim.
+</P>
+
+<P>
+"They didn't come out, an' thot's all there is to it," the foreman was
+saying. "I sint thim in mesilf, and they worked until it was time t'
+set off th' blast. I wint t' get th' fuse, an' I was goin' t' send th'
+black imps out of danger, whin&mdash;whist&mdash;they was gone whin I got
+back&mdash;fifteen of 'em this time!"
+</P>
+
+<P>
+"Do you mean that fifteen more of our men have vanished as the first
+ten did?" asked Job Titus.
+</P>
+
+<P>
+"That's what I mean," asserted the Irishman.
+</P>
+
+<P>
+"It can't be!" declared Walter.
+</P>
+
+<P>
+"Look for yersilf!" returned Tim. "They're not in th' tunnel!"
+</P>
+
+<P>
+"And they didn't come out?"
+</P>
+
+<P>
+"Ask th' time-keeper," and Tim motioned to a young Englishman who,
+since the other disappearance, had been stationed at the mouth of the
+tunnel to keep a record of who went in and came out.
+</P>
+
+<P>
+"No, sir! Nobody kime hout, sir!" the Englishman declared. "Hi 'aven't
+been away frim 'ere, sir, not since hi wint on duty, sir. An' no one
+kime out, no, sir!"
+</P>
+
+<P>
+"We've got to stop this!" declared Job Titus.
+</P>
+
+<P>
+"I should say so!" agreed his brother.
+</P>
+
+<P>
+With Tom and Tim the Titus brothers went into the tunnel. It was
+deserted, and not a trace of the men could be found. Their tools were
+where they had been dropped, but of the men not a sign.
+</P>
+
+<P>
+"There must be some secret way out," declared Tom.
+</P>
+
+<P>
+"Then we'll find it," asserted the brothers.
+</P>
+
+<P>
+Work on the tunnel was stopped for a day, and, keeping out all natives,
+the contractors, with Tom and such white men as they had in their
+employ, went over every foot of roof, sides and floor in the big shaft.
+But not a crack or fissure, large enough to permit the passage of a
+child, much less a man, could be found.
+</P>
+
+<P>
+"Well, I give up!" cried Walter Titus in despair. "There must be
+witchcraft at work here!"
+</P>
+
+<P>
+"Nonsense!" exclaimed his brother. "It's more likely the craft of
+Blakeson & Grinder, with Waddington helping them."
+</P>
+
+<P>
+"Well, if a human agency made these twenty-five men disappear, prove
+it!" insisted Walter.
+</P>
+
+<P>
+His brother did not know what to say.
+</P>
+
+<P>
+"Well, go on with the work," was Job's final conclusion. "We'll have
+one of the white men constantly in the tunnel after this whenever a
+gang is working. We won't leave the natives alone even long enough to
+go to get a fuse. They'll be under constant supervision."
+</P>
+
+<P>
+The tunnel was opened for work, but there were no workers. The morning
+after the investigation, when the starting whistle blew there was no
+line of Indians ready to file into the big, black hole. The huts where
+they slept were deserted. A strange silence brooded over the tunnel
+camp.
+</P>
+
+<P>
+"Where are the men, Serato?" asked Tom of the Indian foreman.
+</P>
+
+<P>
+"Men um gone. No work any more. What you call a hit."
+</P>
+
+<P>
+"You mean a strike?" asked Tom.
+</P>
+
+<P>
+"Sure&mdash;strike&mdash;hit&mdash;all um same. No more work&mdash;um 'fraid!"
+</P>

+
+<P>
+"Well, if this isn't the limit!" cried Tom Swift. "As if we didn't
+have trouble enough without a strike on our hands!"
+</P>
+
+<P>
+"I should say yes!" chimed in Job Titus.
+</P>
+
+<P>
+"Do you mean that the men won't work any more?" asked his brother of
+the native foreman.
+</P>
+
+<P>
+"Sure, no more work&mdash;um much 'fraid big devil in tunnel carry um off
+an' eat um."
+</P>
+
+<P>
+"Well, I don't know that I blame 'em for being a bit frightened,"
+commented Job. "It is a queer proceeding how twenty-five men can
+disappear like that. Where have the men gone, Serato?"
+</P>
+
+<P>
+"Gone home. No more work. Go on hit&mdash;strike&mdash;same like white men."
+</P>
+
+<P>
+"They waited until pay day to go on strike," commented the bookkeeper,
+a youth about Tom's age.
+</P>
+
+<P>
+This was true. The men had been paid off the day before, and usually on
+such occasions many of them remained away, celebrating in the nearest
+village. But this time all had left, and evidently did not intend to
+come back.
+</P>
+
+<P>
+"We'll have to get a new gang," said Job. "And it's going to delay us
+just at the wrong time. Well, there's no help for it. Get busy, Serato.
+You and Tim go and see how many men you can gather. Tell them we'll
+give them a sol a week more if they do good work. (A sol is the
+standard silver coin of Peru, and is worth in United States gold about
+fifty cents.)
+</P>
+
+<P>
+"Half a dollar a day more will look mighty big to them," went on the
+contractor. "Get the men, Serato, and we'll raise your wages two sols a
+week."
+</P>
+
+<P>
+The eyes of the Indian gleamed, and he went off, saying.
+</P>
+
+<P>
+"Um try, but men much 'fraid."
+</P>
+
+<P>
+Whether Serato used his best arguments could not, of course, be
+learned, but he came back at the close of the day, unaccompanied by any
+workers, and he shook his head despondently.
+</P>
+
+<P>
+"Indians no come for one sol, mebby not for two," he said. "I no can
+git."
+</P>
+
+<P>
+"Then I'll try!" cried Job. "I'll get the workers. I'll make our old
+ones come back, for they'll be the best."
+</P>
+
+<P>
+Accompanied by his brother and Tom he went to the various Indian
+villages, including the one whence most of the men now on strike had
+come. The fifteen missing ones were not found, though, as before, their
+relatives, and, in some cases, their families, did not seem alarmed.
+But the men who had gone on strike were found lolling about their
+cabins and huts, smoking and taking their ease, and no amount of
+persuasion could induce them to return.
+</P>
+
+<P>
+Some of them said they had worked long enough and were tired, needing a
+rest. Others declared they had money enough and did not want more. Even
+two more sols a week would not induce them to return.
+</P>
+
+<P>
+And many were frankly afraid. They said so, declaring that if they went
+back to the tunnel some unknown devil might carry them off under the
+earth.
+</P>
+
+<P>
+Job Titus and his brother, who could speak the language fairly well,
+tried to argue against this. They declared the tunnel was perfectly
+safe. But one native worker, who had been the best in the gang, asked:
+</P>
+
+<P>
+"Where um men go?"
+</P>
+
+<P>
+The contractors could not answer.
+</P>
+
+<P>
+"It's a trick," declared Walter. "Our rivals have induced the men to go
+on strike in order to hamper us with the work so they'll get the job."
+</P>
+
+<P>
+But the closest inquiry failed to prove this statement. If Blakeson &
+Grinder, or any of their agents, had a hand in the strike they covered
+their operations well. Though diligent inquiry was made, no trace of
+Waddington, or any other tool, could be found.
+</P>
+
+<P>
+Tom, who had some sort of suspicion of the bearded man on the steamer,
+tried to find him, even taking a trip in to Lima, but without avail.
+</P>
+
+<P>
+The tunnel work was at a standstill, for there was little use in
+setting off blasts if there were no men to remove the resulting piles
+of debris. So, though Tom was ready with some specially powerful
+explosive, he could not use it.
+</P>
+
+<P>
+Efforts were made to get laborers from another section of the country,
+but without effect. The contractors heard of a big force of Italians
+who had finished work on a railroad about a hundred miles away, and
+they were offered places in the tunnel. But they would not come.
+</P>
+
+<P>
+"Well, we may as well give up," said Walter, despondently, to his
+brother one day. "We'll never get the tunnel done on time now."
+</P>
+
+<P>
+"We still have a margin of safety," declared job. "If we could get the
+men inside of a couple of weeks, and if Tom's new powder rips out more
+rock, we'll finish in time."
+</P>
+
+<P>
+"Yes, but there are too many ifs. We may as well admit we've failed."
+</P>
+
+<P>
+"I'll never do that!"
+</P>
+
+<P>
+"What will you do?"
+</P>
+
+<P>
+But Job did not know.
+</P>
+
+<P>
+"If we could git a gang of min from the ould sod&mdash;th' kind I used t'
+work wit in N'Yark," said Tim Sullivan, "I'd show yez whot could be
+done! We'd make th' rock fly!"
+</P>
+
+<P>
+But that efficient labor was out of the question now. The tunnel camp
+was a deserted place.
+</P>
+
+<P>
+"Come on, Koku, we'll go hunting," said Tom one day. "There's no use
+hanging around here, and some venison wouldn't go bad on the table."
+</P>
+
+<P>
+"I'll come, too," said Mr. Damon. "I haven't anything to do."
+</P>
+
+<P>
+The Titus brothers had gone to a distant village, on the forlorn hope
+of getting laborers, so Tom was left to his own devices, and he decided
+to go hunting with his electric rifle.
+</P>
+
+<P>
+The taruco, or native deer, had been plentiful in the vicinity of the
+tunnel until the presence of so many men and the frequent blasts had
+driven them farther off, and it was not until after a tramp of several
+miles that Tom saw one. Then, after stalking it a little way, he
+managed to kill it with the electric rifle.
+</P>
+
+<P>
+Koku hoisted the animal to his big shoulders, and, as this would
+provide meat enough for some time, Tom started back for camp.
+</P>
+
+<P>
+As he and Mr. Damon, with Koku in the rear, passed through a little
+clearing, they saw, on the far side, a native hut. And from it rushed
+a woman, who approached Tom, casting herself on her knees, while she
+pressed his free hand to her head.
+</P>
+
+<P>
+"Bless my scarf pin!" exclaimed Mr. Damon. "What does this mean, Tom?"
+</P>
+
+<P>
+"Oh, this is the mother of the child I saved from the condor," said
+Tom. "Every time she sees me she thanks me all over again. How is the
+baby?" he asked in the Indian tongue, for he was a fair master of it by
+now.
+</P>
+
+<P>
+"The baby is well. Will the mighty hunter permit himself to enter my
+miserable hovel and partake of some milk and cakes?"
+</P>
+
+<P>
+"What do you say, Mr. Damon?" Tom asked. "She's clean and neat, and she
+makes a drink of goat's milk that isn't bad. She bakes some kind of
+meal cakes that are good, too. I'm hungry."
+</P>
+
+<P>
+"All right, Tom, I'll do as you say."
+</P>
+
+<P>
+A little later they were partaking of a rude, but none the less
+welcome, lunch in the woman's hut, while the baby whose life Tom had
+saved cooed in the rough log cradle.
+</P>
+
+<P>
+"Say, Masni," asked Tom, addressing the woman by name, "don't you know
+where we can get some men to work the tunnel?" Of course Tom spoke the
+Indian language, and he had to adapt himself to the comprehension of
+Masni.
+</P>
+
+<P>
+"Men no work tunnel?" she inquired.
+</P>
+
+<P>
+"No, they've all skipped out&mdash;vamoosed. Afraid of some spirit."
+</P>
+
+<P>
+The woman looked around, as though in fear. Then she approached Tom
+closely and whispered:
+</P>
+
+<P>
+"No spirit in tunnel&mdash;bad man!"
+</P>
+
+<P>
+"What!" cried Tom, almost jumping off his stool. "What do you mean,
+Masni?"
+</P>
+
+<P>
+"Me tell mighty hunter," she went on, lowering her voice still more.
+"My man he no want to tell, he 'fraid, but I tell. Mighty hunter save
+Vashni," and she looked toward the baby. "Me help friends of mighty
+hunter. Bad man in tunnel&mdash;no spirit!
+</P>
+
+<P>
+"Men go. Spirit no take um&mdash;bad man take um."
+</P>
+
+<P>
+"Where are they now?" asked Tom. "Jove, if I could find them the secret
+would be solved!"
+</P>
+
+<P>
+The woman looked fearfully around the hut and then whispered:
+</P>
+
+<P>
+"You come&mdash;me show!"
+</P>
+
+<P>
+"Bless my toothbrush!" cried Mr. Damon. "What is going to happen, Tom
+Swift?"
+</P>
+
+<P>
+"I don't know," was the answer, "but something sure is in the wind. I
+guess I shot better than I knew when I killed that condor."

+Despair
+</H3>
+
+<P>
+Calling to a girl of about thirteen years to look after her baby, Masni
+slipped along up a rough mountain trail, motioning to Tom, Mr. Damon
+and Koku to follow. Or rather, the woman gave the sign to Tom, ignoring
+the others, who, naturally, would not be left behind. Masni seemed to
+have eyes for no one but the young inventor, and the manner in which
+she looked at him showed the deep gratitude she felt toward him for
+having saved her baby from the great condor.
+</P>
+
+<P>
+"Come," she said, in her strange Indian tongue, which Tom could
+interpret well enough for himself now.
+</P>
+
+<P>
+"But where are we going, Masni?" he asked. "This isn't the way to the
+tunnel."
+</P>
+
+<P>
+"Me know. Not go to tunnel now," was her answer. "Me show you men."
+</P>
+
+<P>
+"But which men do you mean, Masni?" inquired Tom. "The lost men, or the
+bad ones, who are making trouble for us? Which men do you mean?"
+</P>
+
+<P>
+Masni only shook her head, and murmured: "Me show."
+</P>
+
+<P>
+Probably Tom's attempt to talk her language was not sufficiently clear
+to her.
+</P>
+
+<P>
+"My man&mdash;he good man," she said, coming to a pause on the rough trail
+after a climb which was not easy.
+</P>
+
+<P>
+"Yes, I know he is," Tom said. "But he went on a strike with the
+others, Masni. He no work. He go on a 'hit,' as Serato calls it," and
+Tom laughed.
+</P>
+
+<P>
+"My man he good man&mdash;but he 'fraid," said the wife. "He want to tell
+you of bad mans, but he 'fraid. You save my baby, I no 'fraid. I tell."
+</P>
+
+<P>
+"Oh, I see," said Tom. "Your husband would have given away the secret,
+only he's afraid of the bad men. He likes me, too?"
+</P>
+
+<P>
+"Sure!" Masni exclaimed. "He want tell, but 'fraid. He go 'way, I tell."
+</P>
+
+<P>
+Tom was not quite sure what it all meant, but it seemed that after his
+slaying of the condor both parents were so filled with gratitude that
+they wanted to reveal some secret about the tunnel, only Masni's
+husband was afraid. She, however, had been braver.
+</P>
+
+<P>
+"Something is going to happen," said Tom Swift. "I feel it in my bones!"
+</P>
+
+<P>
+"Bless my porous plaster!" cried Mr. Damon. "I hope it isn't anything
+serious."
+</P>
+
+<P>
+"We'll see," Tom went on.
+</P>
+
+<P>
+They resumed their journey up the mountain trail. It wound in and out
+in a region none of them had before visited. Though it could not be
+far from the tunnel, it was almost a strange country to Tom.
+</P>
+
+<P>
+Suddenly Masni stopped in a narrow gorge where the walls of rock rose
+high on either hand. She seemed looking for something. Her sharp, black
+eyes scanned the cliff and then with an exclamation of satisfaction she
+approached a certain place. With a quick motion she pulled aside a mass
+of tangled vines, and disclosed a path leading down through a V shaped
+crack in the cliff.
+</P>
+
+<P>
+"Mans down there," she said. "You go look."
+</P>
+
+<P>
+For a moment Tom hesitated. Was this a trap? If he and his friends
+entered this narrow and dark opening might not the Indian woman roll
+down some rock back of them, cutting off forever the way of escape?
+</P>
+
+<P>
+Tom turned and looked at Masni. Then he was ashamed of his suspicion,
+for the honest black face, smiling at him, showed no trace of guile.
+</P>
+
+<P>
+"You go&mdash;you see lost men," the woman urged.
+</P>
+
+<P>
+"Come on!" cried Tom. "I believe we're on the track of the mystery!"
+</P>
+
+<P>
+He led the way, followed by Mr. Damon, while Koku came next and then
+Masni. It could be no trap since she entered it herself.
+</P>
+
+<P>
+The path widened, but not much. There was only room for one to walk at
+a time. The trail twisted and turned, and Tom was wondering how far it
+led, when, from behind him, came the cry of the woman:
+</P>
+
+<P>
+"Watch now&mdash;no fall down."
+</P>
+
+<P>
+Tom halted around a sharp turn, and stood transfixed at the sight which
+met his gaze. He found himself looking out through a crack in the face
+of a sheer stone cliff that went straight down for a hundred feet or
+more to a green-carpeted valley.
+</P>
+
+<P>
+Tom was standing in a narrow cleft of rock&mdash;the same rock through which
+they had made their way. And at the foot of the cliff was a little
+encampment of Indians. There were a dozen huts, and wandering about
+them, or sitting in the shade, were a score or more of Indians.
+</P>
+
+<P>
+"There men from tunnel," said Masni, and, as he looked, wondering, Tom
+saw some of the workers he knew. One especially, was a laborer who
+walked with a peculiar limp.
+</P>
+
+<P>
+"The missing men!" gasped the young inventor.
+</P>
+
+<P>
+"Bless my almanac!" cried Mr. Damon. "Where?"
+</P>
+
+<P>
+"Here," answered Tom. "If you squeeze past me you can see them."
+</P>
+
+<P>
+Mr. Damon did so.
+</P>
+
+<P>
+"How did they get here?" asked the odd man, as he looked down in the
+little valley where the missing ones were sequestered.
+</P>
+
+<P>
+"That's what we've got to find out," Tom said. "At any rate here they
+are, and they seem to be enjoying life while we've been worrying as to
+what had become of them. How did they get here, Masni?"
+</P>
+
+<P>
+"Me show you. Come."
+</P>
+
+<P>
+"Wait until I take another look," said Tom.
+</P>
+
+<P>
+"Be careful they don't see you," cautioned Mr. Damon.
+</P>
+
+<P>
+"They can't very well. The cleft is screened by bushes."
+</P>
+
+<P>
+Tom looked down once more on the group of men who had so mysteriously
+disappeared. The little valley stretched out away from the face of the
+cliff, through which, by means of the crack, or cleft in it, Tom and
+the others had come. Tom looked down the wall of rock. It was as smooth
+as the side of a building, and offered no means of getting down or up.
+Doubtless there was an easier entrance to the valley on the other side.
+It was like looking down into some vast hall through an upper window or
+from a balcony.
+</P>
+
+<P>
+"And those men have been in hiding, or been hidden here, ever since
+they disappeared from the tunnel," said Mr. Damon.
+</P>
+
+<P>
+"It doesn't look as though they were detained by force," Tom remarked.
+"I think they are being paid to stay away. How did they get here,
+Masni?"
+</P>
+
+<P>
+"Me show you. Come!"
+</P>
+
+<P>
+They went back along the trail that led through the split in the rock,
+until they had come to the place where the natural curtain of vines
+concealed the entrance. Tom took particular notice of this place so he
+would know it again.
+</P>
+
+<P>
+Then Masni led them over the mountain, and this time Tom saw that they
+were approaching the tunnel. He recognized some places where he had
+taken samples of rock from the outcropping to test the strength of his
+explosive.
+</P>
+
+<P>
+Reaching a certain wild and desolate place, Masni made a signal of
+caution. She seemed to be listening intently. Then, as if satisfied
+there was no danger, she parted some bushes and glided in, motioning
+the others to follow.
+</P>
+
+<P>
+"Now I wonder what's up," Tom mused.
+</P>
+
+<P>
+He and the others were soon informed.
+</P>
+
+<P>
+Masni stopped in front of a pile of brush. With a few vigorous motions
+of her arms she swept it aside and revealed a smooth slab of rock. In
+the centre was what seemed to be a block of metal Masni placed her foot
+on this and pressed heavily.
+</P>
+
+<P>
+And those watching saw a strange thing.
+</P>
+
+<P>
+The slab of rock tilted to one side, as if on a pivot, revealing a
+square opening which seemed to lead through solid stone. And at the far
+end of the opening Tom Swift saw a glimmer of light.
+</P>
+
+<P>
+Stooping down, he looked through the hole thus strangely opened and
+what he saw caused him to cry out in wonder.
+</P>
+
+<P>
+"It's the tunnel!" he cried. "I can look right down into the tunnel.
+It's the incandescent lights I see. I can look right at the ledge of
+rock where I kept watch that day, and where I saw&mdash;where I saw the face
+of Waddington!" he cried. "It wasn't a dream after all. This is a
+shaft connecting with the tunnel. We didn't discover it because this
+rock fits right in the opening in the roof. It must have been there all
+the while, and some blast brought it to light. Is this how the men got
+out, or were taken out of the tunnel, Masni?" Tom asked.
+</P>
+
+<P>
+"This how," said the Indian woman. "See, here rope!"
+</P>
+
+<P>
+She pawed aside a mound of earth, and disclosed a rope buried there, a
+rope knotted at intervals. This, let down through the hole in the roof
+of the tunnel, provided a means of escape, and in such a manner that
+the disappearance of the men was most mysterious.
+</P>
+
+<P>
+"I see how it is!" cried Tom. "Some one interested, Waddington
+probably, who knew about this old secret shaft going down into the
+earth, used it as soon as our blasting was opened that far. They got
+the men out this way, and hid them in the secret valley."
+</P>
+
+<P>
+"But what for?" cried Mr. Damon.
+</P>
+
+<P>
+"To cripple us! To cause the strike by making our other workers afraid
+of some evil spirit! The men were taken away secretly, and, doubtless,
+have been kept in idleness ever since&mdash;paid to stay away so the mystery
+would be all the deeper. Our rivals finding they couldn't stop us in
+any other way have taken our laborers away from us."
+</P>
+
+<P>
+"Bless my meal ticket! It does look like that!" cried Mr. Damon.
+</P>
+
+<P>
+"Of course that's the secret!" cried Tom. "Blakeson & Grinder, or some
+of their tools&mdash;probably the bearded man or Waddington&mdash;found out about
+this shaft which led down into our tunnel. They induced the first ten
+men to quit, and when Tim went to get the fuse the rope was let down,
+and the men climbed up here, one after the other. Those Indians can
+climb like cats. Once the ten were out the shaft was closed with the
+rock, and the ten men taken off to the valley to be secreted there.
+</P>
+
+<P>
+"The same was done with the next fifteen, and, I suppose, if the strike
+hadn't come, more of our workers would have been induced to leave in
+this way. They're probably being better paid than when earning their
+wages; and their relatives must know where they are, and also be given
+a bonus to keep still. No wonder they didn't make a fuss.
+</P>
+
+<P>
+"And no wonder we couldn't find any opening in the tunnel roof. This
+rock must fit in as smoothly as a secret drawer in the kind of old desk
+where missing wills are found in stories."
+</P>
+
+<P>
+"You say you saw Waddington, or the bearded man?" asked Mr. Damon.
+</P>
+
+<P>
+"At the time," replied Tom, "I thought it was a dream. Now I know it
+wasn't. He must have opened the shaft just as I awakened from a doze.
+He saw me and closed it again. He may have been getting ready then to
+take off more of our men, so as to scare the others. Well, we've found
+out the trick."
+</P>
+
+<P>
+"And what are you going to do next?" asked Mr. Damon.
+</P>
+
+<P>
+"Get those missing men back. That will break the hoodoo, and the others
+will come back to work. Then we'll get on the trail of Waddington, or
+Blakeson & Grinder, and put a stop to this business. We know their
+secret now."
+</P>
+
+<P>
+"You mean to get the men out of the secret valley, Tom?"
+</P>
+
+<P>
+"Yes. There must be some other way into it than down the rock where we
+were. How about it, Masni?" and he inquired as to the valley. The
+Indian woman gave Tom to understand that there was another entrance.
+</P>
+
+<P>
+"Well, close up this shaft now before some one sees us at it&mdash;the
+bearded man, for example," Tom suggested. He took another look down
+into the tunnel, which was now deserted on account of the strike, and
+then Masni pressed on the mechanism that worked the stone. She showed
+Tom how to do it.
+</P>
+
+<P>
+"Just a counter-balanced rock operating on the same principle as does a
+window," Tom explained, after a brief examination. "Probably some of
+the old Indian tribes made this shaft for ceremonial purposes. They
+never dreamed we would drive a tunnel along at the bottom of it. The
+shaft probably opened into a cave, and one of our blasts made it part
+of the tunnel. Well, this is part of the secret, anyhow. Much obliged
+to you, Masni!"
+</P>
+
+<P>
+The Indian woman had indeed revealed valuable information. They
+covered the secret rock with brush, as it had been, hid the rope and
+came away. But Tom knew how to find the place again.
+</P>
+
+<P>
+Events moved rapidly from then on. The Titus brothers were more than
+astonished when Tom told them what he had learned. Masni had told him
+how to get into the secret valley by a round about, but easy trail, and
+thither Tom, the contractors, Mr. Damon and some of the white tunnel
+workers went the next day.
+</P>
+
+<P>
+The sequestered men, taken completely by surprise, tried to bolt when
+they saw that they were discovered, and then, shamefacedly enough,
+admitted their part in the trick.
+</P>
+
+<P>
+They would not, however, reveal who had helped them escape from the
+tunnel. Threats and promises of rewards were alike unavailing, but Tom
+and his employers knew well enough who it was. The tunnel workers
+seemed rather tired of living in comparative luxury and idleness, and
+agreed to come back to their labors.
+</P>
+
+<P>
+They packed up their few belongings, mostly cooking pots and pans, and
+marched out of the valley to the village at Rimac.
+</P>
+
+<P>
+And so the strike was broken.
+</P>
+
+<P>
+The reappearance of the missing men, in better health and spirits than
+when they went away, acted like magic. The other men, who had missed
+their wages, crowded back into the shaft, and the sounds of picks and
+shovels were heard again in the tunnel.
+</P>
+
+<P>
+Whether the missing ones told the real story, or whether they made up
+some tale to account for their absence, Tom and his friends could not
+learn. Nor did the bearded man (if he it were who had helped in the
+plot), nor any representative of Blakeson & Grinder appear. The work on
+the tunnel was resumed as if nothing had happened. But Tom arranged a
+bright light so it would reflect on the spot in the roof where the
+moving rock was, so that if the evil face of the bearded man, or of
+Waddington, appeared there again, it would quickly be seen. A search of
+the neighborhood, and diligent inquiries, failed to disclose the
+presence of any of the plotters.
+</P>
+
+<P>
+And then, as if Fate was not making it hard enough for the tunnel
+contractors, they encountered more trouble. It was after Tom had set
+off a big blast that Tim Sullivan, after inspecting what had happened,
+came out to ask.
+</P>
+
+<P>
+"I soy, Mr. Swift, why didn't yez use more powder?"
+</P>
+
+<P>
+"More powder!" cried Tom. "Why, this is the most I have ever set off."
+</P>
+
+<P>
+"Then somethin's wrong, sor. Fer there's only a little rock down. Come
+an' see fer yersilf."
+</P>
+
+<P>
+Tom hastened in. As the foreman had said, the effect of the blast was
+small indeed. Only a little rock had been shaled off. Tom picked up
+some of this and took it outside for examination.
+</P>
+
+<P>
+"Why, it's harder than the hardest flint we've found yet," he said.
+"The powder didn't make any impression on it at all. I'll have to use
+terrific charges."
+</P>
+
+<P>
+This was done, but with little better effect. The explosive, powerful
+as it was, ate only a little way into the rock. Blast after blast had
+the same poor effect.
+</P>
+
+<P>
+"This won't do," said Job Titus, despairingly, one day. "We aren't
+making any progress at all. There's a half mile of this rock, according
+to my calculations, and at this rate we'll be six months getting
+through it. By that time our limit will be up, and we'll be forced to
+give up the contract What can we do, Tom Swift?"

+<H3 ALIGN="center">
+A New Explosive
+</H3>
+
+<P>
+The young inventor was idly handling some pieces of the very hard rock
+that had cropped out in the tunnel cut. Tom had tested it, he had
+pulverized it (as well as he was able), he had examined it under the
+microscope, and he had taken great slabs of it and set off under it, or
+on top of it, charges of explosive of various power to note the effect.
+But the results had not been at all what he had hoped for.
+</P>
+
+<P>
+"What's to be done, Tom?" repeated the contractor.
+</P>
+
+<P>
+"Well, Mr. Titus," was the answer, "the only thing I see to do is to
+make a new explosive."
+</P>
+
+<P>
+"Can you do it, Tom?"
+</P>
+
+<P>
+The reply was characteristic.
+</P>
+
+<P>
+"I can try."
+</P>
+
+<P>
+And in the days that followed, Tom began work on a new line. He had
+brought from Shopton with him much of the needful apparatus, and he
+found he could obtain in Lima what he lacked.
+</P>
+
+<P>
+A message to his father brought the reply that the new ingredients Tom
+needed would be shipped.
+</P>
+
+<P>
+"The kind of explosive we need to rend that very hard rock," the young
+inventor explained to the Titus brothers, "is one that works slowly."
+</P>
+
+<P>
+"I thought all explosions had to be as quick as a flash," said Walter.
+</P>
+
+<P>
+"Well, in a sense, they do. Yet we have quick burning and slow-burning
+powders, the same as we have fuses. A quick-burning explosive is all
+right in soft rock, or in soil with rock and earth mingled. But in rock
+that is harder than flint if you use a quick explosive, only the outer
+surface of the rock will be scaled off.
+</P>
+
+<P>
+"If you take a hammer and bring it down with all your force on a hard
+rock you may chip off a lot of little pieces, or you may crack the
+rock, but you won't, under ordinary circumstances, pulverize it as we
+want to do in the tunnel.
+</P>
+
+<P>
+"On the other hand, if you take a smaller hammer, and keep tapping the
+rock with comparatively gentle blows, you will set up a series of
+vibrations, that, in time, will cause the hard rock to break up into
+any number of small pieces.
+</P>
+
+<P>
+"Now that is the kind of explosive I want&mdash;one that will deal a
+succession of constant blows at the hard rock instead of one great big
+blast."
+</P>
+
+<P>
+"Can you make it, Tom?"
+</P>
+
+<P>
+"Well, I don't know. I'll do the best I can."
+</P>
+
+<P>
+From then on Tom was busy with his experiments.
+</P>
+
+<P>
+Work on the tunnel did not cease while he was searching for a new
+explosive. There was plenty of the old explosive left and charges of
+this were set off as fast as holes could be drilled to receive it. But
+comparatively little was accomplished. Sometimes more rock would be
+loosed than at others, and the native laborers, now seemingly perfectly
+contented, would be kept busy. Again, when a heavy blast would be set
+off hardly a dozen dump cars could be filled.
+</P>
+
+<P>
+But the work must go on. Already the time limit was getting perilously
+close, and the contractors did not doubt that their rivals were only
+waiting for a chance to step in and take their places.
+</P>
+
+<P>
+Nothing more had been seen or heard of the bearded man, Waddington, or
+Blakeson & Grinder. But that the rival firm had not given up was
+evidenced by the efforts made in New York to cripple, financially, the
+firm in which Tom was interested. In fact, at one time the Titus
+brothers were so tied up that they could not get money enough to pay
+their men. But Tom cabled his father, who was quite wealthy, and Mr.
+Swift loaned the contractors enough to proceed with until they could
+dispose of some securities.
+</P>
+
+<P>
+It might be mentioned that Tom was to get a large sum if the tunnel
+were completed on time, so it was to his interest and his father's, to
+bring this about if he could.
+</P>
+
+<P>
+Tom kept on with his powder experiments. Mr. Damon helped him, for that
+gentleman had succeeded in putting the affairs of the wholesale drug
+business on a firm foundation, and there was no more trouble about
+getting the supplies of cinchona bark to market. The natives seemed to
+have taken kindly to the eccentric man, or perhaps it was the
+reputation of Tom Swift and his electric rifle that induced them to
+work hard.
+</P>
+
+<P>
+It must not be supposed that Professor Bumper was idle all this while.
+</P>
+
+<P>
+He came and went at odd times, accompanied by his little retinue of
+Indians, a guide and a native cook. He would come back to the tunnel
+camp, where he made his headquarters, travel stained, worn and weary,
+with disappointment showing on his face.
+</P>
+
+<P>
+"No luck," he would report. "The hidden city of Pelone is still lost."
+</P>
+
+<P>
+Then he would retire to his tent, to pour over his note-books, and make
+a new translation of the inscription on the golden plates. In a day or
+so, refreshed and rested, he would prepare for another start.
+</P>
+
+<P>
+"I'll find it this time, surely!" he would exclaim, as he marched off
+up the mountain trail. "I have heard of a new valley, never before
+visited by a white man, in which there are some old ruins. I'm sure
+they must be those of Pelone."
+</P>
+
+<P>
+But in a week or so he would come back, worn out and discouraged again.
+</P>
+
+<P>
+"The ruins were only those of a native village," he would say. "No
+trace of an ancient civilization there."
+</P>
+
+<P>
+The professor took little or no interest in the tunnel, though he
+expressed the hope that Tom and his friends would be successful. But
+industrial pursuits had no charm for the scientist. He only lived to
+find the hidden city which was to make him famous.
+</P>
+
+<P>
+He heard the story of the queer shaft leading down into the bore under
+the mountain, and, for a time, hoped that might be some clue to the
+lost Pelone. But, after an examination, he decided it was but the shaft
+to some ancient mine which had not panned out, and so had been
+abandoned after having been fitted with a balanced rocky door, perhaps
+for some heathen religious rite.
+</P>
+
+<P>
+There seemed to be no further trouble among the Indian tunnel workers.
+Those who had disappeared&mdash;who had, seemingly, gone willingly up the
+knotted rope to hide themselves in the valley&mdash;kept on with their work.
+If they told their fellows why and where they had gone, the others gave
+no sign. The evil spirits of the tunnel had been exorcised, and there
+was now peace, save for the blasts that were set off every so often.
+</P>
+
+<P>
+Tom tried combination after combination, testing them inside and
+outside the tunnel, always seeking for an explosive that would give a
+slow, rending effect instead of a quick blow, the power of which was
+soon lost. And at last he announced:
+</P>
+
+<P>
+"I think I have it!"
+</P>
+
+<P>
+"Have you? Good!" cried Job Titus.
+</P>
+
+<P>
+"Yes," Tom went on, "I've got a mixture here that seems to give just
+the effect I want. I tried it on some small pieces of rock, and now I
+want to test it on some large chunks. Have you brought any down
+lately?"
+</P>
+
+<P>
+"Yes, we have some big slabs in there."
+</P>
+
+<P>
+Some large pieces of the hard rock, which had been brought down in a
+recent blast, were taken outside the tunnel, and in them one afternoon
+Tom placed, in holes drilled to receive it, some of his new explosive.
+The rocks were set some distance away from the tunnel camp, and Tom
+attached the electric wires that were to detonate the charge.
+</P>
+
+<P>
+"Well, I guess we're ready," announced the young inventor, as he looked
+about him.
+</P>
+
+<P>
+The tunnel workers had been allowed to go for the day, and in a log
+shack, where they would be safe from flying pieces of rock, were Tom,
+Mr. Damon and the two Titus brothers.
+</P>
+
+<P>
+Tom held the electric switch in his hand, and was about to press it.
+</P>
+
+<P>
+"This explosive works differently from any other," he explained. "When
+the charge is fired there is not instantly a detonation and a bursting.
+The powder burns slowly and generates an immense amount of gas. It is
+this gas, accumulating in the cracks and crevices of the rock, that I
+hope will burst and disintegrate it. Of course, an explosion eventually
+follows, as you will see. Here she goes!"
+</P>
+
+<P>
+Tom pressed the switch and, as he did so, there was a cry of alarm from
+Mr. Damon.
+</P>
+
+<P>
+"Bless my safety match, Tom!" cried the old man. "Look! Koku!"
+</P>
+
+<P>
+For, as the charge was fired, the giant emerged from the woods and
+calmly took a seat on the rock that was about to be broken up into
+fragments by Tom's new explosive.

+<P>
+"Get off there, Koku!"
+</P>
+
+<P>
+"Stand up!"
+</P>
+
+<P>
+"Run!"
+</P>
+
+<P>
+"Get out of the way! That's going up!"
+</P>
+
+<P>
+Thus cried Tom and his friends to the big, good-natured, but somewhat
+stupid, giant who had sat down in the dangerous spot. Koku looked
+toward the hut, in front of which the young inventor and the others
+stood, waving their hands to him and shouting.
+</P>
+
+<P>
+"Get up! Get up!" cried Tom, frantically. The powder is going off,
+Koku!"
+</P>
+
+<P>
+"Can't you stop it?" asked Job Titus.
+</P>
+
+<P>
+"No!" answered Tom. "The electric current has already ignited the
+charge. Only that it's slow-burning it would have been fired long ago.
+Get up, Koku!"
+</P>
+
+<P>
+But the giant did not seem to understand. He waved his hand in friendly
+greeting to Tom and the others, who dared not approach closer to warn
+him, for the explosion would occur any second now.
+</P>
+
+<P>
+Then Mr. Damon had an inspiration.
+</P>
+
+<P>
+"Call him to come to you, Tom!" shouted the odd man. "He always comes
+to you in a hurry, you know. Call him!"
+</P>
+
+<P>
+Tom acted on the suggestion at once.
+</P>
+
+<P>
+"Here, Koku!" he cried. "Come here, I want you! Kelos!"
+</P>
+
+<P>
+This last was a word in the giant's own language, meaning "hurry." And
+Koku knew when Tom used that word that there was need of haste. So,
+though he had sat down, evidently to take his ease after a long tramp
+through the woods, Koku sprang up to obey his master's bidding.
+</P>
+
+<P>
+And, as he did so, something happened. The first spark from the fuse,
+ignited by the electric current, had reached the slow-burning powder.
+There was a crackle of flame, and a dull rumble. Koku sprang up from
+the big stone as though shot. What he saw and heard must have alarmed
+him, for he gave a mighty jump and started to run, at the same time
+shouting:
+</P>
+
+<P>
+"Me come, Master!"
+</P>
+
+<P>
+"You'd better!" cried the young inventor.
+</P>
+
+<P>
+Koku got away only just in time, for when he was half way between the
+group of his friends and the big rock, the utmost force of the
+explosion was felt. It was not so very loud, but the power of it made
+the earth tremble.
+</P>
+
+<P>
+The rock seemed to heave itself into the air, and when it settled back
+it was seen to be broken up into many pieces. Koku looked back over
+his shoulder and gave another tremendous leap, which carried him out of
+the way of the flying fragments, some of which rattled on the roof of
+the log hut.
+</P>
+
+<P>
+"There!" cried Tom. "I guess something happened that time! The rock is
+broken up finer than any like it we tried to shatter before. I think
+I've got the mixture just right!"
+</P>
+
+<P>
+"Bless my handkerchief!" cried Mr. Damon. "Think of what might have
+happened to Koku if he had been sitting there."
+</P>
+
+<P>
+"Well," said Tom, "he might not have been killed, for he would probably
+have been tossed well out of the way at the first slow explosion, but
+afterward&mdash;well, he might have been pretty well shaken up. He got away
+just in time."
+</P>
+
+<P>
+The giant looked thoughtfully back toward the place of the experimental
+blast.
+</P>
+
+<P>
+"Master, him do that?" he asked.
+</P>
+
+<P>
+"I did," Tom replied. "But I didn't think you'd walk out of the woods,
+just at the wrong time, and sit down on that rock."
+</P>
+
+<P>
+"Um," murmured the giant. "Koku&mdash;he&mdash;he&mdash;Oh, by golly!" he yelled. And
+then, as if realizing what he had escaped, and being incapable of
+expressing it, the giant with a yell ran into the tunnel and stayed
+there for some time.
+</P>
+
+<P>
+The experiment was pronounced a great success and, now that Tom had
+discovered the right kind of explosive to rend the very hard rock, he
+proceeded to have it made in sufficiently large quantities to be used
+in the tunnel.
+</P>
+
+<P>
+"We'll have to hustle," said Job Titus. "We haven't much of our
+contract time left, and I have reason to believe the Peruvian
+government will not give any extension. It is to their interest to have
+us fail, for they will profit by all the work we have done, even if
+they have to pay our rivals a higher price than we contracted for. It
+is our firm that will pocket the loss."
+</P>
+
+<P>
+"Well, we'll try not to have that happen," said Tom, with a smile.
+</P>
+
+<P>
+"If you're going to use bigger charges of this new explosive, Tom,
+won't more rock be brought down?" asked Walter Titus.
+</P>
+
+<P>
+"That's what I hope."
+</P>
+
+<P>
+"Then we'll need more laborers to bring it out of the tunnel."
+</P>
+
+<P>
+"Yes, we could use more I guess. The faster the blasted rock is
+removed, the quicker I can put in new charges."
+</P>
+
+<P>
+"I'll get more men," decided the contractor. "There won't be any
+trouble now that the hoodoo of the missing workers is solved. I'll tell
+Serato to scare up all his dusky brethren he can find, and we'll offer
+a bonus for good work."
+</P>
+
+<P>
+The Indian foreman readily agreed to get more laborers.
+</P>
+
+<P>
+"And get some big ones, Serato," urged Job Titus. "Get some fellows
+like Koku," for the giant did the work of three men in the tunnel, not
+because he was obliged to, but because his enormous strength must find
+an outlet in action.
+</P>
+
+<P>
+"Um want mans like him?" asked the Indian, nodding toward the giant. He
+and Koku were not on good terms, for once, when Koku was a hurry, he
+had picked up the Indian (no mean sized man himself) and had calmly set
+him to one side. Serato never forgave that.
+</P>
+
+<P>
+"Sure, get all the giants you can," Tom said. "But I guess there aren't
+any in Peru."
+</P>
+
+<P>
+Where Serato found his man, no one knew, and the foreman would not
+tell; but a day or so later he appeared at the tunnel camp with an
+Indian so large in size that he made the others look like pygmies, and
+many of them were above the average in height, too.
+</P>
+
+<P>
+"Say, he's a whopper all right!" exclaimed Tom. "But he isn't as big or
+as strong as Koku."
+</P>
+
+<P>
+"He comes pretty near it," said Job Titus. "With a dozen like him we'd
+finish the tunnel on time, thanks to your explosive."
+</P>
+
+<P>
+Lamos, the Indian giant, was not quite as large as Koku. That is, he
+was not as tall, but he was broader of shoulder. And as to the
+strength of the two, well, it was destined to be tried out in a
+startling fashion.
+</P>
+
+<P>
+In about a week Tom was ready with his first charges of the new
+explosive. The extra Indians were on hand, including Lamos, and great
+hopes of fast progress were held by the contractors.
+</P>
+
+<P>
+The charge was fired and a great mass of broken rock brought down
+inside the tunnel.
+</P>
+
+<P>
+"That's tearing it up!" cried Job Titus, when the fumes had blown away,
+the secret shaft having been opened to facilitate this. "A few more
+shots like that and we'll be through the strata of hard rock."
+</P>
+
+<P>
+The Indians, Koku and Lamos doing their share of the work, were rushed
+in to clear away the debris, so another charge might be fired as soon
+as possible. This would be in a day or so. The contract time was
+getting uncomfortably close.
+</P>
+
+<P>
+Blast after blast was set off, and good progress was made. But instead
+of half a mile of the extra hard rock the contractors found it would be
+nearer three quarters.
+</P>
+
+<P>
+"It's going to be touch and go, whether or not we finish on time," said
+Mr. Job Titus one afternoon, when a clearance had been made and the men
+had filed out to give the drillers a chance to make holes for a new
+blast.
+</P>
+
+<P>
+Tom was about to make a remark when Tim Sullivan came running out of
+the tunnel, his face showing fright and wonder.
+</P>
+
+<P>
+"What's up now, I wonder," said Mr. Titus. "More men missing?"
+</P>
+
+<P>
+"Quick! Come quick!" cried the Irishman. "Thim two giants is fightin'
+in there, an' they'll tear th' tunnel apart if we don't stop 'em. It's
+an awful fight! Awful!"

+A Great Blast
+</H3>
+
+<P>
+Hardly comprehending what the Irish foreman had said, Tom Swift, the
+Titus brothers and Mr. Damon followed Tim Sullivan back into the
+tunnel. They had not gone far before they heard the murmur of many
+voices, and mingled with that were roarings like those of wild beasts.
+</P>
+
+<P>
+"That's thim!" cried Tim. "They're chawin' each other up!"
+</P>
+
+<P>
+"Koku and that Indian giant fighting!" cried Tom. "What's it all about?"
+</P>
+
+<P>
+"Don't ask me!" shouted Tim. "They've been on bad terms iver since they
+met." This was true enough, for one giant was jealous of the other's
+power, and they were continually trying feats of strength against one
+another. Probably this had culminated in a fight, Tom concluded.
+</P>
+
+<P>
+"And it will be some fight!" mused the young inventor.
+</P>
+
+<P>
+Hurrying on, Tom and his companions came upon a strange and not
+altogether pleasant sight. In an open place in the tunnel, where the
+lights were brightest, and in front of the rocky wall which offered a
+bar to further progress and which was soon to be blasted away,
+struggled the two giants.
+</P>
+
+<P>
+With their arms locked about one another, they swayed this way and
+that&mdash;a struggle between two Titans. Of nearly the same height and
+bigness, it was a wrestling match such as had never been seen before.
+Had it been merely a friendly test of strength it would have been good
+to look upon. But it needed only a glance into the faces of either
+giant to show that it was a struggle in deadly earnest.
+</P>
+
+<P>
+Back and forth they reeled over the rocky floor of the tunnel, bones
+and sinews cracking. One sought to throw the other, and first, as Koku
+would gain a slight advantage, his friends would call encouragement,
+while, when Lamos seemed about to triumph, the Indians favoring him
+would let out a yell of triumph.
+</P>
+
+<P>
+For a few minutes Tom and his friends watched, fascinated. Then they
+saw Koku slip, while Lamos bent him farther toward the earth. The
+Indian giant raised his big fist, and Tom saw in it a rock, which the
+big man was about to bring down on Koku's head.
+</P>
+
+<P>
+"Look out, Koku!" yelled Tom.
+</P>
+
+<P>
+Tom's giant slid to one side only just in time, for the blow descended,
+catching him on his muscular shoulder where it only raised a bruise.
+And then Koku gathered himself for a mighty effort. His face flamed
+with rage at the unfair trick.
+</P>
+
+<P>
+"Bless my bath sponge!" cried Mr. Damon. "This is awful!"
+</P>
+
+<P>
+"They must stop!" said Job Titus. "We can't have them fighting like
+this. It is bad for the others. If it were in fun it would be all
+right, but they are in deadly earnest. They must stop!"
+</P>
+
+<P>
+"Koku, stop!" called Tom. "You must not fight any more!"
+</P>
+
+<P>
+"No fight more!" gasped the giant, through his clenched teeth. "This
+end fight!"
+</P>
+
+<P>
+With a mighty effort he broke the hold of Lamos' arms. Then stooping
+suddenly he seized his rival about the middle, and with a tremendous
+heave, in which his muscles stood out in great bunches while his very
+bones seemed to crack, Koku raised Lamos high in the air. Up over his
+head he raised that mass of muscle, bone and flesh, squirming and
+wriggling, trying in vain to save itself.
+</P>
+
+<P>
+Up and up Koku raised Lamos as the murmur of those watching grew to a
+shout of amazement and terror. Never had the like been seen in that
+land for generations. Up and up one giant raised the other. Then
+calling out something in his native tongue Koku hurled the other from
+him, clear across the tunnel and up against the opposite rocky wall.
+The murmuring died to frightened whispers as Lamos fell in a shapeless
+heap on the floor.
+</P>
+
+<P>
+"Ah!" breathed Koku, stretching himself, and extending his brawny arms.
+"Fight all over, Master."
+</P>
+
+<P>
+"Yes, so it seems, Koku," said Tom, solemnly, "but you have killed him.
+Shame on you!" and he spoke bitterly.
+</P>
+
+<P>
+Job Titus had hurried over to the fallen giant.
+</P>
+
+<P>
+"He isn't dead," he called, "but I guess he won't wrestle or fight any
+more. He's badly crippled."
+</P>
+
+<P>
+"And him no more try to blow up tunnel, either," said Koku in his
+hoarse voice. "Me fix: him! No more him take powder, and make tunnel
+all bust."
+</P>
+
+<P>
+"What do you mean, Koku?" asked Tom. "Is that why you fought him? Did
+he try to wreck the tunnel?"
+</P>
+
+<P>
+"So him done, Master. But Koku see&mdash;Koku stop. Then um fight."
+</P>
+
+<P>
+"Be jabbers an' I wouldn't wonder but what he was right!" cried Tim
+Sullivan, excitedly. "I did see that beggar." and he pointed to Lamos,
+who was slowly crawling away, "at the chist where I kape th' powder,
+but I thought nothin' of it at th' time. What did he try t' do, Koku?"
+</P>
+
+<P>
+Then the giant explained in his own language, Tom Swift translating,
+for Koku spoke English but indifferently well.
+</P>
+
+<P>
+"Koku says," rendered Tom, "that he saw Lamos trying to put a big
+charge of powder up in the place where the balanced rock fits in the
+secret opening of the tunnel roof. The charge was all ready to fire,
+and if the giant had set it off he might have brought down the roof of
+the tunnel and so choked it up that we'd have been months cleaning it
+out. Koku saw him and stopped him, and then the fight began. We only
+saw the end."
+</P>
+
+<P>
+"Bless my shoe string!" gasped Mr. Damon. "And a terrible end it was.
+Will Lamos die?"
+</P>
+
+<P>
+"I don't think so," answered Job Titus. "But he will be a cripple for
+life. Not only would he have wrecked the tunnel, but he would have
+killed many of our men had he set off that blast. Koku saved them,
+though it seems too bad he had to fight to do it."
+</P>
+
+<P>
+An investigation showed that Koku spoke truly. The charge, all ready to
+set off, was found where he had knocked it from the hand of Lamos. And
+so Tom's giant saved the day. Lamos was sent back to his own village, a
+broken and humbled giant. And to this day, in that part of Peru, the
+great struggle between Koku and Lamos is spoken of with awe where
+Indians gather about their council fires, and they tell their children
+of the Titanic fight.
+</P>
+
+<P>
+"It was part of the plot," said Job Titus when the usual blast had been
+set off that day, with not very good results. "This giant was sent to
+us by our rivals. They wanted him to hamper our work, for they see we
+have a chance to finish on time. I think that foreman, Serato, is in
+the plot. He brought Lamos here. We'll fire him!"
+</P>
+
+<P>
+This was done, though the Indian protested his innocence. But he could
+not be trusted.
+</P>
+
+<P>
+"We can't take any chances," said Job Titus. "Our time is too nearly
+up. In fact I'm afraid we won't finish on time as it is. There is too
+much of that hard rock to cut through."
+</P>
+
+<P>
+"There's only one thing to do," said Tom, after an investigation. "As
+you say, there is more of that hard rock than we calculated on. To try
+to blast and take it out in the ordinary way will be useless. We must
+try desperate means."
+</P>
+
+<P>
+"What is that?" asked Walter Titus.
+</P>
+
+<P>
+"We must set off the biggest blast we can with safety. We'll bore a
+lot of extra holes, and put in double charges of the explosive. I'll
+add some ingredients to it that will make it stronger. It's our last
+chance. Either we'll blow the tunnel all to pieces, or we'll loosen
+enough rock to make sufficient progress so we can finish on time. What
+do you say? Shall we take the chance?"
+</P>
+
+<P>
+The Titus brothers looked at one another. Failure stared them in the
+face. Unless they completed the tunnel very soon they would lose all
+the money they had sunk in it.
+</P>
+
+<P>
+"Take the chance!" exclaimed Job. "It's sink or swim anyhow. Set off
+the big blast, Tom."
+</P>
+
+<P>
+"All right. We'll get ready for it as soon as we can."
+</P>
+
+<P>
+That day preparations were made for setting off a great charge of the
+powerful explosive. The work was hurried as fast as was consistent with
+safety, but even then progress was rather slow. Precautions had to be
+taken, and the guards about the tunnel were doubled. For it was feared
+that some word of what was about to be done would reach the rival firm,
+who might try desperate means to prevent the completion of the work.
+</P>
+
+<P>
+There was plenty of the explosive on hand, for Mr. Swift had sent Tom a
+large shipment. All this while no word had come from Mr. Nestor, and
+Tom was beginning to think that his prospective father-in-law was very
+angry with him. Nor had Mary written.
+</P>
+
+<P>
+Professor Bumper came and went as he pleased, but his quest was
+regarded as hopeless now. Tom and his friends had little time for the
+bald-headed scientist, for they were too much interested in the success
+of the big blast.
+</P>
+
+<P>
+"Well, we'll set her off to-morrow," Tom said one night, after a hard
+day's work. "The rocky wall is honeycombed with explosive. If all goes
+well we ought to bring down enough rock to keep the gangs busy night
+and day."
+</P>
+
+<P>
+Everything was in readiness. What would the morrow bring&mdash;success or
+failure?

+Gathered beyond the mouth of the tunnel, far enough away so that the
+wind of the great blast would not bowl them over like ten pins, stood
+Tom Swift and his friends. In his hand Tom held the battery box, the
+setting of the switch in which would complete the electrical circuit
+and set off the hundreds of pounds of explosive buried deep in the hard
+rock.

+

+"Are all the men out?" asked the young inventor of Tim Sullivan, who
+had charge of this important matter. Tim was in sole charge as foreman
+now, having picked up enough of the Indian language to get along
+without an interpreter.
+</P>
+
+<P>
+"All out, sor," Tim responded. "Yez kin fire whin ready, Mr. Swift."

+

+It was a portentous moment. No wonder Tom Swift hesitated. In a sense
+he and his friends, the contractors, had staked their all on a single
+throw. If this blast failed it was not likely that another would
+succeed, even if there should be time to prepare one.
+</P>
+
+<P>
+The time limit had almost expired, and there was still a half mile of
+hard rock between the last heading and the farther end of the big
+tunnel. If the blast succeeded enough rock might be brought down to
+enable the work to go on, by using a night and day shift of men. Then,
+too, there was the chance that the hard strata of rock would come to an
+end and softer stone, or easily-dug dirt, be encountered.
+</P>
+
+<P>
+"Well, we may as well have it over with," said Tom in a low voice.
+Every one was very quiet&mdash;tensely quiet.
+</P>
+
+<P>
+The young inventor looked up to see Professor Bumper observing him.
+</P>
+
+<P>
+"Why, Professor!" Tom exclaimed, "I thought you had gone off to the
+mountains again, looking for the lost city."
+</P>
+
+<P>
+"I am going, Tom, very soon. I thought I would stop and see the effect
+of your big blast. This is my last trip. If I do not find the hidden
+city of Pelone this time, I am going to give up."
+</P>
+
+<P>
+"Give up!" cried Mr. Damon. "Bless my fountain pen!"
+</P>
+
+<P>
+"Oh, not altogether," went on the bald-headed scientist. "I mean I
+will give up searching in this part of Peru, and go elsewhere. But I
+will never completely give up the search, for I am sure the hidden city
+exists somewhere under these mountains," and he looked off toward the
+snow-covered peaks of the Andes.
+</P>
+
+<P>
+Tom looked at the battery box. He drew a long breath, and said:
+</P>
+
+<P>
+"Here she goes!"
+</P>
+
+<P>
+There was a contraction of his hand as he pressed the switch over, and
+then, for perhaps a half second, nothing happened. Just for an instant
+Tom feared something had gone wrong that the electric current had
+failed, or that the wires had become disconnected&mdash;perhaps through some
+action of the plotting rivals.
+</P>
+
+<P>
+And then, gently at first, but with increasing intensity, the solid
+ground on which they were all standing seemed to rock and sway, to
+heave itself up, and then sink down.
+</P>
+
+<P>
+"Bless my&mdash;" began Mr. Damon, but he got no further, for a mighty gust
+of wind swept out of the tunnel, and blew off his hat. That gust was
+but a gentle breeze, though, compared to what followed. For there came
+such a rush of air that it almost blew over those standing near the
+opening of the great shaft driven under the mountain. There was a roar
+as of Niagara, a howling as in the Cave of the Winds, and they all bent
+to the blast.
+</P>
+
+<P>
+Then followed a dull, rumbling roar, not as loud as might have been
+expected, but awful in its intensity. Deep down under the very
+foundations of the earth it seemed to rumble.
+</P>
+
+<P>
+"Run! Run back!" cried Tom Swift. "There's a back-draft and the powder
+gas is poisonous. Stoop down and run back!"
+</P>
+
+<P>
+They understood what he meant. The vapor from the powder was deadly if
+breathed in a confined space. Even in the open it gave one a terrible
+headache. And Tom could see floating out of the tunnel the first wisps
+of smoke from the fired explosive. It was lighter than air, and would
+rise. Hence the necessity, as in a smoke-filled room, of keeping low
+down where the air is purer.
+</P>
+
+<P>
+They all rushed back, stooping low. Mr. Damon stumbled and fell, but
+Koku picked him up and, tucking him under one arm, as he might have
+done a child, the giant followed Tom to a place of safety.
+</P>
+
+<P>
+"Well, Tom, it went off all right," said Mr. Job Titus, as they stood
+among the shacks of the workmen and watched the smoke pouring out of
+the tunnel mouth.
+</P>
+
+<P>
+"Yes, it went off. But did it do the work? That's what we've got to
+find out."
+</P>
+
+<P>
+They waited impatiently for the deadly vapor to clear out of the
+tunnel. It was more than an hour before they dared venture in, and then
+it was with smarting eyes and puckered throats. But the atmosphere was
+quickly clearing.
+</P>
+
+<P>
+"Switch on the lights," cried Tom to Tim, for the illuminating current
+had been cut off when the blast was fired. "Let's see what we've
+brought down."
+</P>
+
+<P>
+Following the eager young inventor came the contractors, some of the
+white workers, Mr. Damon and Professor Bumper. The little scientist
+said he would like to see the effect of the big blast.
+</P>
+
+<P>
+Along they stumbled over pieces of rock, large and small.
+</P>
+
+<P>
+"Some force to it," observed Job Titus, as he observed pieces of rock
+close to the mouth of the tunnel. "If it only exerted the force the
+other way, against the face of the rock, as well as back this way,
+we'll be all right."
+</P>
+
+<P>
+"The greater force was in the opposite direction," Tom said.
+</P>
+
+<P>
+A big search-light had been got ready to flash on the place where the
+blast had been set off. This was to enable them to see how much rock
+had been torn away. And, as they reached the place where the flint-like
+wall had been, they saw a strange sight.
+</P>
+
+<P>
+"Bless my strawberry short-cake!" gasped Mr. Damon. "What a hole!"
+</P>
+
+<P>
+"It is a hole," admitted Tom, in a low voice. "A bigger hole than I
+dared hope for."
+</P>
+
+<P>
+For a great cave, seemingly, had been blown in the face of the rock
+wall that had hindered the progress of the tunnel. A great black void
+confronted them.
+</P>
+
+<P>
+"Shift the light over this way," called Tom to Walter Titus, who was
+operating it. "I can't see anything."
+</P>
+
+<P>
+The great beam of light flashed into the void, and then a murmur of awe
+came from every throat.
+</P>
+
+<P>
+For there, revealed in the powerful electrical rays, was what seemed to
+be a long tunnel, high and wide, as smooth as a paved street. And on
+either side of it were what appeared to be buildings, some low, others
+taller. And, branching off from the main tunnel, or street, were other
+passages, also lined with buildings, some of which had crumbled to
+ruins.
+</P>
+
+<P>
+"Bless my dictionary!" cried Mr. Damon. "What is it?"
+</P>
+
+<P>
+Professor Bumper had crawled forward over the mass of broken rock. He
+gazed as if fascinated at what the searchlight showed, and then he
+cried:
+</P>
+
+<P>
+"I have found it! I have found it! The hidden city of Pelone!"

+Success
+</H3>
+
+<P>
+Had it not been for Tom Swift, the excited professor would have rushed
+pellmell over the jagged pile of rocks into the great cave which had
+been opened by the blast, the cave in which the scientist declared was
+the lost city for which he had been searching. But the young inventor
+grasped Mr. Bumper by the arm.
+</P>
+
+<P>
+"Better wait a bit," Tom suggested. "There may be powder gas in there.
+Some of it must have blown forward."
+</P>
+
+<P>
+"I don't care!" excitedly cried the professor. "That is the hidden
+city! I'm sure of it! I have found it at last! I must go in and examine
+it!"
+</P>
+
+<P>
+"There'll be plenty of time," said Tom. "It isn't going to run away.
+Wait until I make a test Tim, hand me one of those torches."
+</P>
+
+<P>
+Some torches of a very inflammable wood were used to test for the
+presence of the deadly smoke-gas. Lighting one of these, Tom tossed it
+into the big excavation.
+</P>
+
+<P>
+It fell to the stone floor&mdash;to the stone street to be more exact&mdash;and,
+flaring up brightly, further revealed the rows of houses as they stood,
+silent and uninhabited.
+</P>
+
+<P>
+"It's all right," Tom announced. "There's no danger so long as the
+torch burns. You can go on, Professor."
+</P>
+
+<P>
+And Professor Bumper rushed forward, scrambling over the pile of
+blasted rock, followed by Tom and the others. Some of the debris from
+the explosion had fallen into the cave, and was scattered for some
+distance along the main street of what had been Pelone. But beyond that
+the way was clear.
+</P>
+
+<P>
+"Yes, it is Pelone," cried Professor Bumper. "See!"
+</P>
+
+<P>
+He pointed to inscriptions in queer characters over the doorway of some
+of the houses, but he alone could read them.
+</P>
+
+<P>
+"I have found Pelone!" he kept repeating over and over again.
+</P>
+
+<P>
+And that is just what had happened. That last great blast Tom Swift had
+set off had broken down the rock wall that hid the lost city from view.
+There it was, buried deep down under the mountain, where it had been
+covered from sight ages ago by some mighty earthquake or landslide;
+perhaps both. And the earth and rocks had fallen over the main portion
+of the city of Pelone in such a way&mdash;in such an arch formation&mdash;that
+the greater part of it was preserved from the pressure of the mountain
+above it.
+</P>
+
+<P>
+The outlying portions were crushed into dust by the awful pressure of
+the mountain&mdash;millions of tons of stone&mdash;but where the natural arch had
+formed the weight was kept off the buildings, most of which were as
+perfect as they had been before the cataclysm came.
+</P>
+
+<P>
+The buildings were of stone block construction, mostly only one story
+in height, though some were two. They were simply made, somewhat after
+the fashion of the Aztecs. A look into some of them by the light of
+portable electric lamps showed that the houses were furnished with some
+degree of taste and luxury. There were traces of an ancient
+civilization.
+</P>
+
+<P>
+But of the inhabitants, there was not a trace: either they had fled
+before the earthquake or the volcanic eruption had engulfed the city,
+or the countless centuries had turned their very bones to dust.
+</P>
+
+<P>
+"Oh, what a find! What a find!" murmured Professor Bumper. "I shall be
+famous! And so will you, Tom Swift. For it was your blast that revealed
+the lost city of Pelone. Your name will be honored by every
+archeological society in the world, and all will be eager to make you
+an honorary member."
+</P>
+
+<P>
+"That's all very nice," said Tom, "but what pleases me better is that
+this tunnel is a success."
+</P>
+
+<P>
+"Success!" cried Mr. Damon. "I should call it a failure, Tom Swift.
+Why, you've run smack into an old city, and you'll have either to curve
+the tunnel to one side, or start a new one."
+</P>
+
+<P>
+"Nothing of the sort!" laughed Tom. "Don't you see? The tunnel comes
+right up to the main street of Pelone. And the street is as straight as
+a die, and just the width and height of the tunnel. All we will have to
+do will be to keep on blasting away, where the main street comes to an
+end, and our tunnel will be finished. The street is over half a mile
+long, I should judge, and we'll save all that blasting. The tunnel will
+be finished in time!"
+</P>
+
+<P>
+"So it will!" cried Job Titus. "We can use the main street of the
+hidden city as part of the tunnel."
+</P>
+
+<P>
+"Use the street all you like," said Mr. Bumper, "but leave the houses
+to me. They are a perfect mine of ancient lore and information. At last
+I have found it! The ancient, hidden city of Pelone, spoken of on the
+Peruvian tablets, of gold."
+</P>
+
+<P>
+The story of the discoveries the scientist made in Pelone is an
+enthralling one. But this is a story of Tom Swift and his big tunnel,
+and no place for telling of the archeological discoveries.
+</P>
+
+<P>
+Suffice it to say that Professor Bumper, though he found no gold, for
+which the contractors hoped, made many curious finds in the ancient
+houses. He came upon traces of a strange civilization, though he could
+find no record of what had caused the burial of Pelone beneath the
+mountains. He wrote many books about his discovery, giving Tom Swift
+due credit for uncovering the place with the mighty blast. Other
+scientists came in flocks, and for a time Pelone was almost as busy a
+place as it had been originally.
+</P>
+
+<P>
+Even when the tunnel was completed and trains ran through it, the
+scientists kept on with their work of classifying what they found. An
+underground station was built on the main street of the old city, and
+visitors often wandered through the ancient houses, wherein was the
+bone-dust of the dead and gone people.
+</P>
+
+<P>
+But to go back to the story of Tom Swift. Tom's surmise was right. He
+and the contractors were able to use the main street of Pelone as part
+of their tunnel, and a good half mile of blasting through solid rock
+was saved. The flint came to an end at the extremity of Pelone, and the
+last part of the tunnel had only to be dug through sand-stone and soft
+dirt, an easy undertaking.
+</P>
+
+<P>
+So the big bore was finished on time&mdash;ahead of time in fact, and Titus
+Brothers received from Senor Belasdo, the Peruvian representative, a
+large bonus of money, in which Tom Swift shared.
+</P>
+
+<P>
+"So our rivals didn't balk us after all," said Walter Titus, "though
+they tried mighty hard."
+</P>
+
+<P>
+The big tunnel was finished&mdash;at least Tom Swift's work on it. All that
+remained to do was to clear away the debris and lay the connecting
+rails. Tom and Mr. Damon prepared to go back home. The latter's work
+was done. As for Professor Bumper, nothing could take him from Pelone.
+He said he was going to live there, and, practically, he did.
+</P>
+
+<P>
+Tom, Koku and Mr. Damon returned to Lima, thence to go to Callao to
+take the steamer for San Francisco. One day the manager of the hotel
+spoke to them.
+</P>
+
+<P>
+"You are Americans, are you not?" he asked.
+</P>
+
+<P>
+"Yes," answered Tom. "Why?"
+</P>
+
+<P>
+"Because there is another American here. He is friendless and alone,
+and he is dying. He has no friends, he says. Perhaps&mdash;"
+</P>
+
+<P>
+"Of course we'll do what we can for him," said Tom, impulsively. "Where
+is he?"
+</P>
+
+<P>
+With Mr. Damon he entered the room where the dying man lay. He had
+caught a fever, the hotel manager said, and could not recover. Tom,
+catching sight of the sufferer, cried:
+</P>
+
+<P>
+"The bearded man! Waddington!"
+</P>
+
+<P>
+He had recognized the mysterious person who had been on the Bellaconda,
+and the man whose face had stared at him through the secret shaft of
+the tunnel.
+</P>
+
+<P>
+"Yes, the 'bearded man' now," said the sufferer in a hoarse voice, "and
+some one else too. You are right. I am Waddington!"
+</P>
+
+<P>
+And so it proved. He had grown a beard to disguise himself so he might
+better follow Tom Swift and Mr. Titus. And he had followed them,
+seeking to prevent the completion of the tunnel. But he had not been
+successful.
+</P>
+
+<P>
+Waddington it was who had thrown the bomb, though he declared he only
+hoped to disable Tom and Mr. Titus, and not to injure them. He was
+fighting for delay. And it was Waddington, working in conjunction with
+the rascally foreman Serato, who had induced the tunnel workers to
+desert so mysteriously, hoping to scare the other Indians away. He
+nearly succeeded too, had it not been for the gratitude of the woman
+whose baby Tom had saved from the condor.
+</P>
+
+<P>
+Waddington had been an actor before he became involved with the rival
+contractors. He was smooth shaven when first he went to Shopton, to spy
+on Mr. Titus, whose movements he had been commanded to follow by
+Blakeson & Grinder. Then he disappeared after Mr. Titus chased him,
+only to reappear, in disguise, on board the Bellaconda, as Senor Pinto.
+</P>
+
+<P>
+Waddington, meanwhile, had grown a beard and this, with his knowledge
+of theatrical makeup, enabled him to deceive even Mr. Titus. Of course
+it was comparatively easy to deceive Tom, who had not known him.
+Waddington had really been ill when he called for help on the ship, and
+he had not noticed that it was Tom and Mr. Titus who came into his
+stateroom to his aid. When he did recognize them, he relied on his
+disguise to screen him from recognition, and he was successful. He had
+only pretended to be ill, though, the time he slipped out and threw the
+bomb.
+</P>
+
+<P>
+Reaching Peru he at once began his plotting. Serato told him about the
+secret shaft leading into the tunnel, and with the knotted rope, and
+with the aid of the faithless foreman, the men were got out of the
+tunnel and paid to hide away. Waddington was planning further
+disappearances when Tom saw him, but thought it a dream.
+</P>
+
+<P>
+Masni, the Indian woman, out herb-hunting one day, had seen Waddington,
+'the bearded man' as he then was&mdash;working the secret stone. Hidden, she
+observed him and told her husband, who was afraid to reveal what he
+knew. But when Tom saved the baby the woman rewarded him in the only
+way possible. And it was Serato, who, at Waddington's suggestion,
+caused the "hit" among the men by working on their superstitious fears.
+</P>
+
+<P>
+Waddington, knowing that he was dying, confessed everything, and begged
+forgiveness from Tom and his friends, which was granted, in as much as
+no real harm had been done. Waddington was but a tool in the hands of
+the rival contractors, who deserted him in his hour of need. His last
+hours, however, were made as comfortable as possible by the generosity
+of Tom and Mr. Damon.
+</P>
+
+<P>
+No effort was made to bring Blakeson & Grinder to justice, as there was
+no evidence against them after Waddington died. And, as the tunnel was
+finished, the Titus brothers had no further cause for worry.
+</P>
+
+<P>
+"But if it had not been for Tom's big blast, and the discovery of the
+hidden city of Pelone just in the right place, we might be digging at
+that tunnel yet," said Job Titus.
+</P>
+
+<P>
+The day before the steamer was to sail, Tom Swift received a cable
+message. Its receipt seemed to fill him with delight, so that Mr. Damon
+asked:
+</P>
+
+<P>
+"Is it from your father, Tom?"
+</P>
+
+<P>
+"No it's from Mary Nestor. She says her father has forgiven me. They
+have been away, and Mary has been ill, which accounts for no letters up
+to now. But everything is all right now, and they feel that the
+dynamite trick wasn't my fault. But, all the same, I'm going to teach
+Eradicate to read," concluded Tom.
+</P>
+
+<P>
+"I think it would be a good idea," agreed Mr. Damon.
+</P>
+
+<P>
+Tom, Mr. Damon and Koku, bidding farewell to the friends they had made
+in Peru, went aboard the steamer, Job Titus and his brother coming to
+see them off.
+</P>
+
+<P>
+"Give us an option on all that explosive you make, Tom Swift!" begged
+Walter Titus. "We were so successful with this tunnel, thanks to you,
+that the government is going to have us dig another. Will you come
+down and help?"
+</P>
+
+<P>
+"Maybe," said Tom, with a smile. "But I'm going home first," and once
+more he read the message from Mary Nestor.
+</P>
+
+<P>
+And as Tom, on the deck of the steamer, waved his hands to Professor
+Bumper and his other friends whom he was leaving in Peru, we also, will
+say farewell.

+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, is 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.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4

+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
