+CHAPTER I
+
+A BAD PLACE FOR A FIRE
+
+
+"Impossible, Ned! It can't be as much as that!"
+
+"Well, you can prove the additions yourself, Tom, on one of the adding
+machines. I've been over 'em twice, and get the same result each time.
+There are the figures. They say figures don't lie, though it doesn't
+follow that the opposite is true, for those who do not stick closely to
+the truth do, sometimes, figure. But there you have it; your financial
+statement for the year," and Ned Newton, business manager for Tom
+Swift, the talented young inventor, shoved a mass of papers across the
+table to his friend and chum, as well as employer.
+
+"It doesn't seem possible, Ned, that we have made as much as that this
+past year. And this, as I understand it, doesn't include what was taken
+from the wreck of the Pandora?"
+
+Tom Swift looked questioningly at Ned Newton, who shook his head in
+answer.
+
+"You really didn't get anything to speak of out of your undersea
+search, Tom," replied the young financial manager, "so I didn't include
+it. But there's enough without that."
+
+"I should say so!" exclaimed Tom. "Whew!" he whistled, "I didn't think
+I was worth that much."
+
+"Well, you've earned it, every cent, with the inventions of yourself
+and your father."
+
+"And I might add that we wouldn't have half we earn if it wasn't for
+the shrewd way you look after us, Ned," said Tom, with a warm smile at
+his friend. "I appreciate the way you manage our affairs; for, though I
+have had some pretty good luck with my searchlight, wizard camera, war
+tank and other contraptions, I never would have been able to save any
+of the money they brought in if it hadn't been for you."
+
+"Well, that's what I'm here for," remarked Ned modestly.
+
+"I appreciate that," began Tom Swift. "And I want to say, Ned--"
+
+But Tom did not say what he had started to. He broke off suddenly, and
+seemed to be listening to some sound outside the room of his home where
+he and his financial and business manager were going over the year's
+statement and accounting.
+
+Ned, too, in spite of the fact that he had been busy going over
+figures, adding up long columns, checking statements, and giving the
+results to Tom, had been aware, in the last five minutes, of an
+ever-growing tumult in the street. At first it had been no more than
+the passage along the thoroughfare of an unusual number of pedestrians.
+Ned had accounted for it at first by the theory that some moving
+picture theater had finished the first performance and the people were
+hurrying home.
+
+But after he had finished his financial labors and had handed Tom the
+first of a series of statements to look over, the young financial
+expert began to realize that there was no moving picture house near
+Tom's home. Consequently the passing throngs could not be accounted for
+in that way.
+
+Yet the tumult of feet grew in the highway outside. Ned had begun to
+wonder if there had been an attempted burglary, a fight, or something
+like that, calling for police action, which had gathered an unusual
+throng that warm, spring evening.
+
+And then had come Tom's interruption of himself when he broke off in
+the middle of a sentence to listen intently.
+
+"What is it?" asked Ned.
+
+"I thought I heard Rad or Koku moving around out there," murmured Tom.
+"It may be that my father is not feeling well and wants to speak to me
+or that some one may have telephoned. I told them not to disturb me
+while you and I were going over the accounts. But if it is something of
+importance--"
+
+Again Tom paused, for distinctly now in addition to the ever-increasing
+sounds in the streets could be heard a shuffling and talking in the
+hall just outside the door.
+
+"G'wan 'way from heah now!" cried the voice of a colored man.
+
+"It is Rad!" exclaimed Tom, meaning thereby Eradicate Sampson, an aged
+but faithful colored servant. And then the voice of Rad, as he was most
+often called, went on with:
+
+"G'wan 'way! I'll tell Massa Tom!"
+
+"Me tell! Big thing! Best for big man tell!" broke in another voice; a
+deep, booming voice that could only proceed from a powerfully built man.
+
+"Koku!" exclaimed Tom, with a half comical look at Ned. "He and Rad are
+at it again!"
+
+Koku was a giant, literally, and he had attached himself to Tom when
+the latter had made one of many perilous trips. So eager were Eradicate
+and Koku to serve the young inventor that frequently there were more or
+less good-natured clashes between them to see who would have the honor.
+
+The discussion and scuffle in the hall at length grew so insistent that
+Tom, fearing the aged colored man might accidentally be hurt by the
+giant Koku, opened the door. There stood the two, each endeavoring to
+push away the other that the victor might, it appeared, knock on the
+door. Of course Rad was no match for Koku, but the giant, mindful of
+his great strength, was not using all of it.
+
+"Here! what does this mean?" cried Tom, rather more sternly than he
+really meant. He had to pretend to be stern at times with his old
+colored helper and the impulsive and powerful giant. "What are you
+cutting up for outside my door when I told you I must be quiet with Mr.
+Newton?"
+
+"No can be quiet!" declared the giant. "Too much noise in street--big
+crowds--much big!"
+
+He spoke an English of his own, did Koku.
+
+"What are the crowds doing?" asked Ned. "I thought we'd been hearing an
+ever increasing tumult, Tom," he said to the young inventor.
+
+"Big crowds--'um go to see big--"
+
+"Heah! Let me tell Massa Tom!" pleaded Rad. Poor Rad! He was getting
+old and could not perform the services that once he had so readily and
+efficiently done. Now he was eager to help Tom in such small measure as
+carrying him a message. So it was with a feeling of sadness that Tom
+heard the old man say again, pleadingly:
+
+"Let me tell him, Koku! I know all 'bout it! Let me tell Massa Tom whut
+it am, an'--"
+
+"Well, go ahead and tell me!" burst out Tom, with a good-natured laugh.
+"Don't keep me in suspense. If there's anything going on--"
+
+He did not finish the sentence. It was evident that something of moment
+was going on, for the crowds in the street were now running instead of
+walking, and voices could be heard calling back and forth such
+exclamations as:
+
+"Where is it?"
+
+"Must be a big one."
+
+"And with this wind it'll be worse!"
+
+Tom glanced at Ned and then at the two servants.
+
+"Has anything happened?" asked the young inventor.
+
+"Dey's a big fire, Massa Tom!" exploded Rad.
+
+"Heap big blaze!" added Koku.
+
+At the same time, out in the street high and clear, the cry rang out:
+
+"Fire! Fire!"
+
+"Is it any of our buildings?" exclaimed Tom, in his excitement catching
+hold of the giant's arm.
+
+"No, it's quite a way off, on de odder side of town," answered the
+colored man. "But we t'ought we'd better come an' tell yo', an'--"
+
+"Yes! Yes! I'm glad you did, Rad. It was perfectly right for you to
+tell me! I wish you'd done it sooner, though! Come on, Ned! Let's go to
+the blaze! We can finish looking over the figures another time. Is my
+father all right, Rad?"
+
+"Yes, suh, Massa Tom, he's done sleepin' good."
+
+"Then don't disturb him. Mr. Newton and I will go to the fire. I'm
+glad it isn't here," and Tom looked from a side window out on many
+shops that were not a great distance from the house; shops where he and
+his father had perfected many inventions.
+
+The buildings had grown up around the old Swift homestead, which, now
+that so much industry surrounded it, was not the most pleasant place to
+live in. Tom and his father only made this their stopping place in
+winter. In the summer they dwelt in a quiet cottage far removed from
+the scenes of their industry.
+
+"We'll take the electric runabout, Ned," remarked Tom, as he caught up
+a hat from the rack, an example followed by his friend. Together the
+young inventor and the financial manager hurried out to the garage,
+where Tom soon had in operation a small electric automobile, that, more
+than once, had proved its claim to being the "speediest car on the
+road."
+
+As they turned out of the driveway into the street they became aware of
+great crowds making their way toward a glow of sinister red light
+showing in the eastern sky.
+
+"Some blaze!" exclaimed Tom, as he turned on more power.
+
+"You said it!" ejaculated Ned. "Must be a general alarm," he added, as
+they caught the sound from the next street of additional apparatus
+hurrying to the fire.
+
+"Well, I'm glad it isn't on our side of town," remarked Tom, as he
+looked back at the peaceful gloom surrounding and covering his own home
+and work buildings.
+
+"Where do you reckon it is?" asked Ned, as they sped onward.
+
+"Hard to say," remarked the young inventor, as he steered to one side
+to pass a powerful imported automobile which, however, did not have the
+speed of the electric runabout. "A fire at night is always deceiving as
+to direction. But we can locate it when we get to the top of the hill."
+
+Shopton, the suburb of the town where Tom lived, was named so because
+of the many shops that had been erected by the industry of the young
+inventor and his father. In fact the town was named Shopton though of
+late there had been an effort to change the name of the strictly
+residential section, which lay over the hill toward the river.
+
+Tom's car shot up the slope with scarcely any slackening of speed, and,
+as he passed a group of men and boys running onward, Tom shouted:
+
+"Where is it?"
+
+"The fireworks factory!" was the answer.
+
+"Fireworks factory!" cried Ned. "Bad place for a fire!"
+
+"I should say so!" exclaimed Tom.
+
+The chums had become gradually aware of the gale that was blowing, and,
+as they reached the summit of the hill and caught sight of the burning
+factory, they saw the flames being swept far out from it and toward a
+collection of houses on the other side of a vacant lot that separated
+the fireworks industrial plant from the dwellings. As Tom Swift
+glimpsed the fire, noted its proportions and the fierceness of the
+flames, and saw which way the wind was blowing them, he turned on the
+power to the utmost.
+
+"What are you doing, Tom?" yelled Ned.
+
+"I'm going down there!" cried Tom. "That place is likely to explode any
+minute!"
+
+"Then why go closer?" gasped Ned, for his breath was almost taken away
+by the speed of the car, and he had to hold his hat to keep it from
+blowing away. "Why don't you play safe?"
+
+"Don't you understand?" shouted Tom in his chum's ear. "The wind is
+blowing the fire right toward those houses! Mary Nestor lives in one of
+them!"
+
+"Oh--Mary Nestor!" exclaimed Ned. Then he understood--Mary and Tom were
+engaged to be married.
+
+"They may be all right," Tom went on. "I can't be sure from this
+distance. Or they may be in danger. It's a bad fire and--"
+
+His voice was blotted out in the roar of an explosion which seemed to
+hurl back the electric runabout and bring it to a momentary stop.
+
+
+
+
+CHAPTER II
+
+NO USE OF LIVING!
+
+
+Only momentarily was Tom Swift halted in his progress toward the scene
+of the blaze in the fireworks factory. To him, and to the chum who sat
+beside him on the seat of the electric runabout, it appeared that the
+blast had actually stopped the progress of the car. But perhaps that
+was more their imagination than anything else, for the machine swept on
+down the hill, at the foot of which was the conflagration.
+
+"That was a bad one, Ned!" gasped Tom, as he turned to one side to pass
+an engine on its way to the scene of excitement.
+
+"I should say so! Must have been somebody hurt in that blow-up!"
+
+"I only hope it wasn't Mary or her folks!" murmured Tom. "The wind is
+sweeping the fire right that way!"
+
+"What are you going to do, Tom?" yelled his chum, as the business
+manager saw the young inventor heading directly for the blaze. "What's
+the idea?"
+
+"To rescue Mary, if she's in danger!"
+
+"I'm with you!" was Ned's quick response. "But you can't go any closer.
+The police are stretching the fire lines!"
+
+"I guess they'll let me through!" said Tom grimly.
+
+He slowed his car as he approached a place where an officer was driving
+back the throng that sought to come closer to the blaze.
+
+"Git back! Git back, I tell you!" stormed the policeman, pushing
+against the packed bodies of men and boys. "There'll be another blow-up
+in a minute or two, and a lot more of you killed!"
+
+"Are there any killed?" asked Tom, stopping the car near the officer.
+
+"I guess so--yes. And some of the houses are catching. Git back now!
+You, too, with that car! You'll have to back up!"
+
+"I've got to go through!" replied Tom, with tightening lips. "I've got
+to go through, Cassidy!" He knew the officer, and the latter now
+seemed, for the first time, to recognize the young inventor.
+
+"Oh, it's you, is it, Mr. Swift?" he exclaimed. "Well, go ahead. But be
+careful. 'Tis dangerous there--very dangerous, an'--"
+
+His voice was lost in the roar of another explosion, not as loud or
+severe as the first, but more plainly felt by Tom and Ned, for they
+were nearer to it.
+
+"Now will you git back!" cried Policeman Cassidy, and the crowd did,
+without further urging.
+
+Tom started the runabout forward again.
+
+"We've got to rescue Mary!" he said to Ned, who nodded.
+
+In another moment the two young men were lost to sight in a swirl of
+smoke that swept across the street. And while they are thus temporarily
+hidden may not this opportunity be taken of telling new readers
+something of the hero of this story?
+
+The young inventor was introduced in the first volume of this series,
+called "Tom Swift and his Motor Cycle." It was Tom's first venture into
+the realms of invention, after he had purchased from Mr. Wakefield
+Damon a speedy machine that tried to climb a tree with that excitable
+gentleman.
+
+Tom, with the help of his father, an inventor of note, rebuilt the
+motor cycle adding many improvements, and it served Tom in good stead
+more than once.
+
+From then on the career of Tom Swift was steadily onward and upward.
+One new invention led to another from his second venture, a motor boat,
+through an airship and other marvels, and eventually to a submarine. In
+each of these vehicles of motion and travel Tom and his friends, Ned
+Newton and Mr. Damon, had many adventures, detailed in the respective
+volumes.
+
+His venture in proceeding to save Mary Nestor from possible danger in
+the blaze of the fireworks factory was not the first time Tom had
+rendered service to the Nestor family. There was that occasion on which
+he had sent his wireless message from Earthquake Island, as related in
+an earlier volume.
+
+Space forbids the detailing of all that had happened to the young
+inventor up to the time of the opening of this story. Sufficient to
+say that Tom's latest achievement had been the recovery of treasure
+from the depths of the ocean.
+
+Tom Swift's activities in connection with his inventions had become so
+numerous that the Swift Construction Company, of which Ned Newton was
+financial manager and Mr. Damon one of the directors, had been formed.
+And when the rumor came that there was a chance to salvage some of the
+untold wealth at the bottom of the sea, Tom was interested, as were his
+friends.
+
+It was decided to search for the wreck of the Pandora, sunk in the West
+Indies, and one of Tom's latest submarine craft was utilized for this
+purpose.
+
+Not to go into all the details, which are given in the last volume of
+this series, entitled "Tom Swift and His Undersea Search," suffice it
+to say that the venture was begun. Matters were complicated owing to
+the fact that Mary Nestor's uncle, Barton Keith, was in trouble over
+the loss of valuable papers proving his title to some oil lands. Mary
+mentioned that a person, Dixwell Hardley, was the man who, it was
+supposed, was trying to defraud her relative. And the complications may
+be imagined when it is said that this same Hardley was the man who had
+interested Tom in the undersea search for the riches of the Pandora.
+
+Tom had been at home some time now, and it was while going over his
+accounts with Ned, and, incidentally, planning new activities, that the
+cry of fire broke in on them.
+
+"Whew, Tom, some heat there!" gasped Ned, lowering his arm from his
+face, an action which had been necessitated by Tom's daring in driving
+the car close to the blazing fireworks factory.
+
+"I should say so!" agreed Tom. "I can almost smell the rubber of my
+tires burning. But we're out of the worst of it."
+
+"Lucky she didn't take the notion to blow up as we were passing,"
+grimly commented Ned. "Where are you aiming for now?"
+
+"Mary's house. It's just beyond here. But we can't see it on account of
+the smoke."
+
+A few seconds later they had passed through the black pall that was
+slashed here and there with red slivers of flame, and, coming to a more
+open space, Ned and Tom cleared their eyes of smoke.
+
+"I guess there's no immediate danger," remarked Tom, as he saw that the
+home of Mary Nestor and the houses near her residence were, for the
+time being, out of the path of the flames. The explosion had blown down
+part of the blazing factory nearest the residential section, and the
+flames had less to feed on.
+
+But the conflagration was still a fierce one. Not half the big factory
+was yet consumed, and every now and then there would sound dull,
+booming reports, causing nervous screams from the women who were out in
+front of their homes, while the men would crouch down as though fearing
+a shower of fiery embers.
+
+"Oh, Tom, I'm so glad you're here!" cried Mary, as the runabout drew up
+in front of her home. "Do you think it will be much worse?" and she
+clutched his arm, as he got down to speak to her.
+
+"I think the worst is over, as far as you people here are concerned,"
+the young inventor replied. "The wind has shifted a bit."
+
+"And there are several engines near us, Tom," said Mr. Nestor, coming
+forward. "The firemen tell me they will play streams of water on the
+roofs and outsides of our houses if the flames start this way again."
+
+"That ought to do the trick," said Tom, with a show of confidence.
+"Anybody hurt around here?" he asked. "One of the policeman said he
+heard several were killed."
+
+"They may have been--in the factory," said Mr. Nestor. "Of course if
+the fire and explosions had taken place in the daytime the loss of life
+would have been great. But most of the workers had left some time
+before the blaze was discovered. There are a few men on a night shift,
+though, and I shouldn't be surprised but what some of them had
+suffered."
+
+"Too bad!" murmured the young inventor. "You're not worried about your
+home, are you, Mrs. Nestor?" he asked of Mary's mother.
+
+"Oh, Tom, I certainly am!" she exclaimed. "I wanted to bring out our
+things, but Mr. Nestor said it wouldn't be of any use."
+
+"Neither it would, if we've got to burn, but I don't believe we
+have--now," said her husband. "That last explosion and the shift of the
+wind saved us. I appreciate your coming over, Tom," he went on. "We
+might have needed your help. It's queer there isn't some better, or
+more effective, way of fighting a fire than just pouring on a
+comparatively insignificant bit of water," he added, as, from what was
+now a safe distance, they watched the firemen using many lines of hose.
+
+"They do have chemical extinguishers," said Ned.
+
+"Yes, for little baby blazes that have just started," went on Mr.
+Nestor. "But in all the progress of science there has not been much
+advance in fighting fires. We still do as they did a hundred years
+ago--squirt water on it, and mighty little of it compared to the blaze.
+It would take a week to put this fire out by the water they are using
+if it were not for the fact that the blaze eats itself up and has
+nothing more to feed on."
+
+"We'll have to get Tom to invent a new way of fighting fire," remarked
+Ned.
+
+The young inventor was about to reply when several firemen, equipped
+with smoke helmets which they adjusted as they ran, came running down
+the street.
+
+"What's the matter?" asked Tom of one whom he knew.
+
+"Some men are trapped in a small shed back of the factory," was the
+answer. "We just heard of it, and we're going in after them. Oh!
+Oh--my--my heart!" he gasped, and he sank to the sidewalk. Evidently
+he was either overcome by the smoke and poisonous gases or by his
+exertions.
+
+Tom grasped the situation instantly. Taking the smoke helmet from the
+exhausted fire-fighter, the young inventor shouted:
+
+"I'll fill your place! See if you can grab a hat, Ned, and come on!"
+
+One of the other firemen had two helmets, and he offered Ned one.
+Pausing only long enough to see that Mr. Nestor and some others were
+looking after the exhausted "smoke-eater," Ned raced on after Tom. The
+two young men, following the firemen, made their way around the end of
+the factory to the smoke-filled yard in the rear. But for the helmets,
+which were like the gas masks of the Great War, they would not have
+been able to live.
+
+One of the firemen pointed through the luridly-lighted smoke to a small
+structure near the main building. This was beginning to burn. With
+quick blows of an axe the door was hewed down, and the rescue party,
+including Tom and Ned, made its way inside. In the light from the
+blaze, as it filtered through the windows, it could be seen that a man
+lay in a huddled heap on the floor.
+
+By motions the leader of the rescue squad made it clear that the man
+was to be carried out, and Tom helped with this while Ned, using an
+axe, cleared away some debris to enable the door to be opened fully so
+the men could pass out carrying their burden.
+
+The man was taken to the Nestor yard and stretched out on the grass.
+Word was relayed to one of the ambulance doctors who were on the scene
+attending to several injured firemen, and in a short time the man, who,
+it appeared, had been overcome by smoke, was revived.
+
+"Well, that was a narrow squeak for you," said one of the firemen, glad
+to breathe without a mask on.
+
+"Yes, it was touch and go," remarked the young doctor, who had used
+heroic measures to bring the man back from the brink of the grave. "But
+you'll live now, all right."
+
+The revived man looked dully about him. He seemed somewhat bewildered.
+
+"Of what use to live?" he murmured. "You might as well have let me die
+in there. Life isn't worth living now," and he sank into a stupor,
+while Tom and the others looked wonderingly at one another.
+
+
+
+
+CHAPTER III
+
+TOM'S NEW IDEA
+
+
+"What's the matter with him, Doctor?" asked Tom in a low voice of the
+young physician who had been working over the man. "Do you think he is
+worse hurt than appears? Is he dying, and is his mind wandering?"
+
+"I don't believe so," answered the doctor. "At least I don't believe
+that he is dying, though his mind may be wandering. He isn't
+injured--at least not outwardly. Just temporarily overcome by smoke is
+what it looks like to me. But of course I haven't made a thorough
+examination."
+
+"Hadn't we better get him into the house, Doctor?" asked Mr. Nestor,
+who stood with Tom, Ned and a group of men and boys about the inert
+form of the man lying on the grass. The rescued one was again seemingly
+unconscious.
+
+"The best medicine he can have is fresh air," the doctor replied. "He's
+better off out here than in the house. Though if he doesn't revive
+presently I will send him to the hospital."
+
+The man did not appear to be so badly off but what he could hear, and
+at these words he opened his eyes again.
+
+"I don't want to go to the hospital," he murmured. "I'll be all right
+presently, and can go home, though--Oh, well, what's the use?" he asked
+wearily, as though he had given up some fight. "I've lost everything."
+
+"Well, you've got a deal of life left in you yet; and that's more than
+you could say of some who have come out of smaller fires than this,"
+said one of the firemen who, with Tom, had carried the man out of the
+shed. "Come on, we'd better be getting back," he said to his companion.
+"The worst of it is over, but there'll be plenty to do yet."
+
+"You said it!" commented the other grimly.
+
+They went out of the Nestor yard, many of the crowd that had gathered
+during the rescue following. The doctor administered some more
+stimulant in the shape of aromatic spirits of ammonia to the man, who,
+after his momentary revival, had again lapsed into a state of stupor.
+
+"Who is he?" asked Tom, as the physician knelt down beside the silent
+form.
+
+"I don't know," said Mr. Nestor. "I know quite a number connected with
+the fireworks factory, but this man is a stranger to me."
+
+"I've seen him going into the main offices several times," remarked
+Mary, who was standing beside Tom. "He seemed to be one of the company
+officers."
+
+"I don't believe so, Mary," stated her father. "I know most of the
+fireworks company officials, and I'm sure this man is not one of them.
+Poor fellow! He seems to be in a bad way."
+
+"Mentally, as well as physically," put in Ned. "He acted as if sorry
+that we had saved his life."
+
+"Too bad," murmured Mary, and then a policeman, who had just come into
+the yard to get the facts for his report, looked at the figure lying on
+the grass, and said:
+
+"I know him."
+
+"You do?" cried Tom. "Who is he?"
+
+"Name's Baxter, Josephus Baxter. He's a chemist, and he works in the
+fireworks factory here. Not as one of the hands, but in the experiment
+laboratory. I've seen him there late at night lots of times. That's how
+I got acquainted with him. He was going in around two o'clock one
+morning, and I stopped him, thinking he was a thief. He proved his
+identity, and I've passed the time of day with him many a time since."
+
+"Where does he live?" asked Mr. Nestor.
+
+"Down on Clay Street," and the officer mentioned the number. "He lives
+all alone, so he told me. He's some sort of an inventor, I guess. At
+least I judged so by his talk. Do you want an ambulance, Doctor?" he
+asked the physician.
+
+"No, I think he's coming around all right," was the answer. "If we had
+an auto we could send him home."
+
+"I'll take him in the runabout," eagerly offered Tom. "But if he lives
+all alone will it be safe to leave him in his house?"
+
+"He ought to be looked after, I suppose," the doctor stated. "He'll be
+all right in a day or so if no complications set in, but he'll be weak
+for a while and need attention."
+
+"Then I'll take him home with me!" announced Tom. "We have plenty of
+room, and Mrs. Baggert will feel right at home with some one to nurse.
+Bring the runabout here, will you please, Ned?"
+
+As Ned darted off to run up the machine, the man opened his eyes again.
+For a moment he did not seem to know where he was or what had happened.
+Then, as he saw the lurid light of the flames which were now dying away
+and realized his position, he sighed heavily and murmured:
+
+"It's all over!"
+
+"Oh, no, it isn't!" cheerfully exclaimed the doctor. "You will be all
+right in a few days."
+
+"Myself, yes, maybe," said the man bitterly, and he managed to rise to
+his feet. "But what of my future? It is all gone! The work of years is
+lost."
+
+"Burned in the fire?" asked Tom, wondering whether the man was a major
+stockholder in the company. "Didn't you have any insurance? Though I
+suppose you couldn't get much on a fireworks plant," he added, for he
+knew something of insurance matters in connection with his own business.
+
+"Oh, it isn't the fire--that is directly," said the man, in the same
+bitter tones. "I've lost everything! The scoundrels stole them! And
+I--Oh, never mind!" he cried. "What's the use of talking? I'm down and
+out! I might just as well have died in the fire!"
+
+Tom was about to make some remark, but the doctor motioned to him to
+refrain, and then Ned came up with the runabout. At first Josephus
+Baxter, which was the name of the man who had been rescued, made some
+objections to going to Tom's home. But when it was pointed out that he
+might lapse into a stupor again from the effects of the smoke poisons,
+in which event he would have no one to minister to him at his lonely
+home, he consented to go to the residence of the young inventor.
+
+"Though if I do lapse into unconsciousness you might as well let me
+keep on sleeping until the end," said Mr. Baxter bitterly to Tom and
+Ned, as they drove away from the scene of the fire with him.
+
+"Oh, you'll feel better in the morning," cheerfully declared Ned.
+
+The man did not answer, and the two chums did not feel much like
+talking, for they were worn out and weary from their exertions at the
+fire. The factory had been pretty well consumed, though by strenuous
+labors the blaze had not extended to adjoining structures. The home of
+Mary Nestor was saved, and for this Tom Swift was thankful.
+
+Mrs. Baggert, the Swift's housekeeper, was indeed glad to have some one
+to "fuss over," as Tom put it. She prepared a bed for Mr. Baxter, and
+in this the weary and ill man sank with a sigh of relief.
+
+"Can I do anything for you?" asked Tom, as he was about to go out and
+close the door.
+
+"No--thank you," was the halting reply. "I guess nothing can be done.
+Field and Melling have me where they want me now--down and out."
+
+"Do you mean Amos Field and Jason Melling of the fireworks firm?" asked
+Tom, for the names were familiar to him in a business way.
+
+"Yes, the--the scoundrels!" exclaimed Mr. Baxter, and from his voice
+Tom judged that he was growing stronger. "They pretended to be my
+friends, giving me a shop in which to work and experiment, and when the
+time came they took my secret formulae. I believe that is what they
+started the fire for--to conceal their crime!"
+
+"You don't mean that!" cried Tom. "Deliberately to start a fire in a
+factory where there was powder and other explosives! That would be a
+terrible crime!"
+
+"Field and Melling are capable of just such crimes as that!" said
+Josephus Baxter, bitterly. "If they took my formulae they wouldn't stop
+at arson."
+
+"Were your formulae for the manufacture of fireworks?" asked Tom.
+
+"Not altogether," was the reply. "I had several formulae for valuable
+chemical combinations. They could be used in fireworks, and that is why
+I could use the laboratory here. But the main use of my discoveries is
+in the dye industry. I would have been a millionaire soon, with the
+rise of the American dye industry following the shutting out of the
+Germans after the war. But now, with my secret formulae gone, I am no
+better than a beggar!"
+
+"Perhaps it will not be as bad as you think," said Tom, recognizing the
+fact that Mr. Baxter was in a nervous and excited state. "Matters may
+look brighter in the morning."
+
+"I don't see how they can," was the grim answer. "However, I appreciate
+all that you have done for me. But I fear my case is hopeless."
+
+"I'll see you again in the morning," Tom said, trying to infuse some
+cheerfulness into his voice.
+
+He found Ned waiting for him when he came downstairs.
+
+"How is he?" asked the young business manager.
+
+"In rather a bad way--mentally, at least," and Tom told of the lost
+formulae. "Do you know, Ned," he went on, "I have an idea!"
+
+"You generally do have--lots of 'em!" Ned rejoined.
+
+"But this is a new one," went on Tom. "You saw what trouble they had
+this evening to get a stream of water to the top stories of that
+factory, didn't you?"
+
+"Yes, the pressure here isn't what it ought to be," Ned agreed. "And
+some of our engines are old-timers."
+
+"Why is it necessary always to fight a fire with water?" Tom continued.
+"There are plenty of chemicals that will put out a fire much quicker
+than water."
+
+"Of course," Ned answered. "There are plenty of chemical fire
+extinguishers on the market, too, Tom. If your idea is to invent a new
+hand grenade, stay off it! A lot of money has been lost that way."
+
+"I wasn't thinking of a hand grenade," said Tom, as he drew some sheets
+of paper across the table to him. "My idea is on a bigger scale.
+There's no reason, Ned, why a big fire in a tall building, like a
+sky-scraper, shouldn't be fought from above, as well as from below. Now
+if I had the right sort of chemicals I could--"
+
+Tom paused in a listening attitude. There was the rush of feet and a
+voice cried:
+
+"I'll get them! I'll get the scoundrels!"
+
+
+
+
+CHAPTER IV
+
+AN EXPERIMENT
+
+
+"That can't be Koku and Rad in one of their periodic squabbles, can
+it?" asked Ned.
+
+"No. It's probably Mr. Baxter," Tom answered. "The doctor said he might
+get violent once or twice, until the effects of his shock wore off.
+There is some quieting medicine I can give him. I'll run up."
+
+"Guess I'd better go along," remarked Ned. "Sounds as if you'd need
+help."
+
+And it did appear so, for again the frenzied shouts sounded:
+
+"I'll get 'em! I'll get the scoundrels who stole my secret formulae
+that I worked over so many years! Come back now! Don't put the match
+near the powder!"
+
+Tom and Ned hurried to the room where the unfortunate chemist had been
+put to bed, to find him out in the hall, wrapped in a bedquilt, and
+with Mrs. Baggert vainly trying to quiet him. Mr. Baxter stared at Tom
+and Ned without seeing them, for he was in a delirium of fever.
+
+"Have you my formulae?" he asked. "I want them back!"
+
+"You shall have them in the morning," replied Tom soothingly. "Lie
+down, and I'll bring them to you in the morning. And drink this," he
+added, holding out a glass of soothing mixture which the doctor had
+ordered in case the patient should become violent.
+
+Josephus Baxter glared about with wild eyes, but between them Tom and
+Mrs. Baggert managed to get him to drink the mixture.
+
+"Bah! It's as bad as some of my chemicals!" spluttered the chemist, as
+he handed back the glass. "You are sure you'll have my formulae in the
+morning?" he asked, as he turned to go back to his room.
+
+"I'll do my best," declared Tom cheerfully. "Now please lie down."
+
+Which, after some urging, Mr. Baxter consented to do. Eradicate wanted
+to lie down in the hall outside the excited chemist's door to guard
+against his emerging again, but Tom decided on Koku. The giant, though
+not as intelligent as the colored man, was more efficient in an
+emergency because of his great strength. Eradicate was getting old,
+and there was a pathetic droop to his figure as he shuffled off when
+Koku superseded him.
+
+"Ah done guess Ah ain't wanted much mo'," muttered Rad sadly.
+
+"Oh, yes, you are!" cried Tom, as, the excitement over, he walked
+downstairs with Ned. "I'm going to start something new, Rad, and I'll
+need your help."
+
+"Will yo', really, Massa Tom?" exclaimed faithful Rad, his face
+lighting up. "Dat's good! Is yo' goin' off after mo' diamonds, or up to
+de caves of ice?"
+
+"Not quite that," answered the young inventor, recalling the stirring
+experiences that had fallen to him when on those voyages. "I'm going to
+work around home, Rad, and I'll need your help."
+
+"Anyt'ing yo' wants, Massa Tom! Anyt'ing yo' wants!" offered the now
+delighted Rad, and he went to bed much happier.
+
+"Well, to resume where we left off," began Ned, when he and Tom were
+once more by themselves, "what's the game?"
+
+"Oh, I don't know that it's much of a game," was the answer. "But I
+just have an idea that a big fire in a towering building can be fought
+from above with chemicals, as well as from the ground with streams of
+water.
+
+"Well, I guess it could be," Ned agreed. "But how are you going to get
+your chemicals in at the top? Shoot 'em up through a hose? If you do
+that you'll need a special kind of hose, for the chemicals will rot
+anything like rubber or canvas."
+
+"I wasn't thinking of a hose," returned Tom. "What then?" asked the
+young financial manager.
+
+"An airship!" Tom exclaimed with such sudden energy that Ned started.
+"It just came to me!" explained the youthful inventor. "I was
+wondering how we could get the chemicals in from the top, and an
+airship is the solution. I can sail over the burning building and drop
+the chemicals down. That will douse the blaze if my plans go right."
+
+Ned was silent a moment, considering Tom's daring plan and project.
+Then, as it became clearer, the young banker cried:
+
+"Blamed if I don't think that's just the thing, Tom! It ought to work,
+and, if it does, it will save a lot of lives, to say nothing of
+property! A fire in a sky-scraper ought to be fought from above. Then
+the extinguisher element, whether chemicals or water, could be dropped
+where they'd do the most good. As it is now, with water, a lot of it is
+wasted. Some of it never reaches the heart of the fire, being splashed
+on the outside of the building. A lot more turns to steam before it
+hits the flames, and only a small percentage is really effective."
+
+"That's my notion," Tom said.
+
+"Then go ahead and do it!" urged his friend. "You have my permission!"
+
+"Thanks," commented Tom dryly. "But there are several things to be
+worked out before we can start. I've got to devise some scheme for
+carrying a sufficient quantity of chemicals, and invent some way of
+releasing them from an airship over the blaze. But that last part ought
+to be easy, for I think I can alter my warfare bomb-dropping attachment
+to serve the purpose.
+
+"What I really need, however, is some new chemical combination that
+will quickly put a really big blaze out of business. There are any
+number of these chemicals, but most of them depend on the production of
+carbon dioxide. This is the product of some solution of a carbonate and
+sulphuric acid, and I suppose, eventually, I'll work out something on
+that order. But I hope I may get something better."
+
+"You haven't delved much into chemistry, have you?"
+
+"No. And I wish now that I had. I see my limitations and realize my
+weakness. But I can brush up a little on my chemistry. As for the
+mechanical part, that of dropping the extinguisher on the blaze, I'm
+not worrying over that end."
+
+"No," agreed Ned. "You have enough types of airships to be able to
+select just the best one for the purpose. But, say, Tom!" he suddenly
+cried, "why not ask him to help you?"
+
+"Who?"
+
+"Mr. Baxter. He's a chemist. And though he says his formulae are about
+dyes and fireworks, maybe he can put you in the way of inventing a
+chemical solution that will be death to fires."
+
+"He might," Tom agreed. "But I think he'll be out of business for some
+time. This shock--being overcome by smoke and his secret formulae
+having been stolen--seem to have affected his mind. I don't know that I
+could depend on him."
+
+"It's worth trying," declared Ned. "What do you suppose he means, Tom,
+saying that Field and Melling stole his formulae?"
+
+"Haven't the least idea. I only know those fireworks firm members
+slightly, if at all. I'm not sure I'd recognize them if I met them. But
+they are reputed to be wealthy, and I hardly think they would stoop to
+stealing some inventor's formulae.
+
+"We inventors are a suspicious lot, Ned, as you probably have found
+out," he added with a smile. "We imagine the rest of the world is out
+to cheat us, and I presume Josephus Baxter is no exception. Still,
+there may be some truth in his story. I'll give him all the help I can.
+But I'm going into the aerial fire-fighting game. I've been waiting for
+something new, and this may be it."
+
+"You may count on me!" declared Ned. "And now, unless you're going to
+sit up all night and start studying chemistry, you'd better come to
+bed."
+
+"That's right. Tomorrow is another day. I hope Mr. Baxter gets some
+rest. Sleep will improve him a lot, the doctor said."
+
+"I know one friend of yours who will be glad to know that you are going
+to start something," remarked Ned, as he and Tom started for their
+rooms, for the young manager was staying with his friend for the night.
+
+"Who?" Tom wanted to know.
+
+"Mr. Wakefield Damon," was the answer. "He hasn't been over lately,
+Tom."
+
+"No, he's been off on a little trip, blessing everything from his
+baggage check to his suspender buttons," laughed the young inventor, as
+he recalled his eccentric acquaintance. "I shall be glad to see him
+again."
+
+"He'll be right over as soon as he learns what's in the wind,"
+predicted Ned.
+
+The hopes that Mr. Baxter would be greatly improved in the morning were
+doomed to disappointment. He was in no actual danger, the doctor said,
+but his recovery from the effects of the smoke he had breathed was not
+as rapid as desired or hoped for.
+
+"He's suffering from some shock," said the physician, "and his mental
+condition is against him. He ought to be kept quiet, and if you can't
+have him here, Mr. Swift, I can arrange to have him sent to a hospital."
+
+"I wouldn't dream of it!" Tom exclaimed. "Let him stay here by all
+means. We have plenty of room, and Mrs. Baggert has been wishing for
+some one to nurse. Now she has him."
+
+So it was arranged that the chemist should remain at the Swift home,
+and he gave a languid assent when they spoke to him of the matter. He
+really was much more ill than seemed at first.
+
+But as everything possible had been done, Tom decided to go ahead with
+the new idea that had come to him--that of inventing an aerial chemical
+fire-fighting machine.
+
+"And if we get a chance, Ned, we'll try to get back those secret
+formulae Mr. Baxter claims to have lost," Tom declared. "I have heard
+some stories about that fireworks firm, which make me believe there may
+be something in Baxter's story."
+
+"All right, Tom, I'm with you any time you need me," Ned promised.
+
+The young inventor lost little time in beginning his operations. As he
+had said, the chief need was a fire extinguishing chemical solution or
+powder. Tom resolved to try the solution first, as it was easier to
+make. With this end in view he proceeded to delve into old and new
+chemistry books. He also sought the advice of his father.
+
+And one day, when Ned called, Tom electrified his chum with the
+exclamation:
+
+"Well, I'm going to give it a try!"
+
+"What?"
+
+"My aerial chemical fire-fighting apparatus. Of course I only have the
+chemical yet. I haven't worked on the carrying apparatus nor decided
+how I will attach it to an airship. But I'm going up now with some of
+my new solution and drop it on a blaze from above."
+
+"Where are you going to get the fire?" asked Ned. "You can't have a
+sky-scraper blaze made to order, you know."
+
+"No, but as this is only an experiment," Tom said, "a big bonfire will
+answer the purpose. I'm having Koku and Rad make one now down in our
+big meadow. As soon as it gets hot enough and fierce enough, I'll sail
+over it in my small machine, drop the extinguisher on it, and see what
+happens. Want to come?"
+
+"Sure thing!" cried Ned. "And I hope the experiment is a success!"
+
+"Thanks," murmured Tom. "I'm about ready to start. All I have to do is
+to take this tank up with me," and he pointed to one containing his new
+mixture. "Of course the arrangement for dumping it out of the aircraft
+is very crude," Tom said. "But I can work on that later."
+
+Ned and he were busy putting the can of Tom's new chemical extinguisher
+in the airship when the door of the hangar was suddenly opened and a
+very much excited man entered crying:
+
+"Fire! Fire! Bless my kitchen sink, your meadow's on fire, Tom Swift!
+It's blazing high! Fire! Fire!"
+
+
+
+
+CHAPTER V
+
+THE EXPLOSION
+
+
+Tom and Ned were so startled by the entrance of the excited man with
+his cry of "Fire!" that the young inventor nearly dropped the tank of
+liquid extinguisher he was helping to hoist into the aeroplane. Then,
+as he caught sight of his visitor, Tom exclaimed:
+
+"Hello, Mr. Damon! We were wondering whether you'd be along to witness
+our first experiment."
+
+"Experiment, Tom Swift! Experiment! Bless my Latin grammar! but you'd
+much better be calling out the fire department to play on that blaze
+down in your meadow. What is it--your barns or one of your new shops?"
+
+"Neither one, Mr. Damon," laughed Ned. "It's only a blaze that Koku and
+Rad started."
+
+"And the fire department is here," added Tom.
+
+"Where?" inquired the eccentric man.
+
+"Here," and Tom pointed to his airship--one of the smaller craft--into
+which the tank of chemicals had been hoisted.
+
+"Oh!" exclaimed Mr. Damon. "Something new, eh, Tom?" His eyes glistened.
+
+"Yes. Fighting fires from the air. I got the idea after the fireworks
+factory went up in smoke. Will you come along? There's plenty of room."
+
+"I believe I will," assented Mr. Damon. It was not the first time, by
+any means, that he had gone aloft with Tom. "I happened to be coming
+over in my auto," he went on to explain, "when I happened to see the
+fire down in the meadow. I was afraid you didn't know about it."
+
+"Oh, yes," replied Tom. "I had Rad and Koku light a big pile of packing
+boxes, to represent, as nearly as possible, on a small scale, a burning
+building. I plan now to sail over it and drop the tins of chemicals.
+They are arranged to burst as they fall into the blaze, and I hope the
+carbon dioxide set loose will blanket out the fire."
+
+"Sounds interesting," commented Mr. Damon. "I'll go along."
+
+The airship was wheeled out of the hangar and was soon ready for the
+flight. A big cloud of black vapor down in the meadow told Tom and Ned
+that Koku and Eradicate had done their work well. The giant and the
+colored man had poured oil over the wood to make a fierce blaze that
+would give Tom's new chemical combination a severe test.
+
+A mechanic turned the propeller of the airship until there was an
+accumulation of gas in the different cylinders. Then he stepped back
+while Tom threw on the switch. This was not one of the self-starting
+types, of which Tom possessed one or two.
+
+"Contact!" cried Tom sharply, and the man stepped forward to give the
+big blades a final turn that would start the motor. There was a
+muffled roar and then a steady staccato blending of explosions. Tom
+raced the motor while his men held the machine in place, and then,
+satisfied that all was well, the young inventor gave the word, and the
+craft raced over the ground, to soar aloft a little later.
+
+Tom, Ned and Mr. Damon could look down to the meadow where the bonfire
+was blazing. A crowd had collected, but the heat of the blaze kept them
+at a good distance. Then, as many of the throng caught sight of the
+airship overhead, there was a new interest for them.
+
+Tom had told Ned and Mr. Damon, before the trio had entered the
+machine, what he wanted them to do. This was to toss the chemicals
+overboard at the proper time. Of course in his perfected apparatus Tom
+hoped to have a device by which he could drop the fire extinguishing
+elements by a mere pressure of his finger or foot, as bombs were
+released from aircraft during the war. But this would serve for the
+time being.
+
+Nearer and nearer the blaze the airship approached until it was almost
+above it. Tom had had some experience in bomb-dropping, and knew when
+to give the signal.
+
+At last the signal came. Mr. Damon and Ned heaved over the side the
+metal containers of the powerful chemicals.
+
+Down they went, unerring as an arrow, though on a slant, caused by the
+impetus given them by the speed of the airship.
+
+Tom and his friends leaned over the side of the machine to watch the
+effect. They could see the chemicals strike the blaze, and it was
+evident from the manner in which the fire died down that the containers
+had broken, as Tom intended they should to scatter their contents.
+
+"Hurray!" cried Ned, forgetting that he could not be heard, for no head
+telephones were used on this occasion and the roar of the motor would
+drown any human voice. "It's working, Tom!"
+
+Truly the effect of the chemicals was seemingly to cause the fire to go
+out, but it was only a momentary dying down. Koku and Rad had made a
+fierce, yet comparatively small, conflagration, and though for a time
+the gas generated by Tom's mixture dampened the blaze, in a few
+seconds--less than half a minute--the flames were shooting higher than
+ever.
+
+Tom made a gesture of disappointment, and swung his craft around in a
+sharp, banking turn. He had no more chemicals to drop, as he had
+thought this supply would be sufficient. However, he had guessed badly.
+The fire burned on, doing no damage, of course, for that had been
+thought of when it was started in the meadow.
+
+"Something wrong!" declared the young inventor, when they were back at
+the hangar, climbing out of the machine.
+
+"What was it?" asked Ned.
+
+"Didn't use the right kind of chemicals," Tom answered. "From the way
+the flames shot up, you'd think I had poured oil on the blaze instead
+of carbon dioxide."
+
+"Bless my insurance policy, Tom!" cried Mr. Damon, "but I'd hate to
+trust to your apparatus if my house caught."
+
+"Don't blame you," Tom assented. "But I'll do the trick yet! This is
+only a starter!"
+
+During the next two weeks the young inventor worked hard in his
+laboratory, Mr. Swift sometimes helping him, but more often Koku and
+Eradicate. Mr. Baxter had recovered sufficiently to leave the Swift
+home. But though the chemist seemed well physically, his mind appeared
+to be brooding over his loss.
+
+"If I could only get my secret formulae back!" he sighed, as he thanked
+Tom for his kindness. "I'm sure Field and Melling have them. And I
+believe they got them the night of the fireworks blaze; the scoundrels!"
+
+"Well, if I can help you, please let me," begged Tom. And then he
+dismissed the matter from his mind in his anxiety to hit upon the right
+chemical mixture for putting out fires from the air.
+
+One afternoon, at the end of a week in which he had been busily and
+steadily engaged on this work, Tom finally moved away from his
+laboratory table with a sigh of relief, and, turning to Eradicate, who
+had been helping him, exclaimed:
+
+"Well, I think I have it now!"
+
+"Good lan' ob massy, I hopes so!" exclaimed the colored man. "It sho'
+do smell bad enough, Massa Tom, to make any fire go an' run an' drown
+hisse'f! Whew-up! It's turrible stuff!"
+
+"Yes, it isn't very pleasant," Tom agreed, with a smile. "Though I am
+getting rather used to it. But when it's in a metal tube it won't
+smell, and I think it will put out any fire that ever started. We'll
+give it a test now, Rad. Just take that flask of red stuff and pour it
+into this one of yellow. I'll go out and light the bonfire, and we'll
+make a small test."
+
+Leaving Rad to mix some of the chemicals, a task the colored man had
+often done before, Tom went out into the yard near his laboratory to
+start a blaze on which his new mixture could be tested.
+
+He had not got far from the laboratory door when he felt a sudden jar
+and a rush of air, and then followed the dull boom of an explosion.
+Like an echo came the voice of Eradicate:
+
+"Oh, Massa Tom, I'se blowed up! It done sploded right in mah face!"
+
+
+
+
+CHAPTER VI
+
+TOM IS WORRIED
+
+
+Dropping what he had in his hands, Tom Swift raced back to the
+laboratory where he had left Eradicate to mix the chemicals. Again the
+despairing, frightened cry of the colored man rang out.
+
+"I hope nothing serious has happened," was the thought that flashed
+through Tom's mind. "But I'm afraid it has. I should have mixed those
+new chemicals myself."
+
+Koku, the giant, who was at work in another part of the shop yard,
+heard Rad's cry and came running up. As there was always more or less
+jealousy between Eradicate and Koku, the latter now thought he had a
+chance to crow over his rival, not, of course, understanding what had
+happened.
+
+"Ho! Ho!" laughed Koku. "You much better hab me work, Master Tom. I no
+make blunderstakes like dat black fellow! I never no make him!"
+
+"I don't know whether Rad has made a mistake or not," murmured Tom.
+"Come along, Koku, we may need your help. There has been an explosion."
+
+"Yep, dat Rad he don't as know any more as to blow up de whole place!"
+chuckled Koku.
+
+He thought he would have a chance to make fun of Eradicate, but neither
+he nor Tom realized how serious had been the happening. As the young
+inventor reached the laboratory, which he had left but a few seconds
+before, he saw the interior almost in ruins. All about were scattered
+various pieces of apparatus, test tubes, alembics, retorts, flasks, and
+an electric furnace.
+
+But what gave Tom more concern than anything else was the sight of
+Eradicate lying in the midst of broken glass on the floor. The colored
+man was moaning and held his hands over his face, and the young
+inventor could see that the hands, which had labored so hard and
+faithfully in his service, were cut and bleeding.
+
+"Rad! Rad! what has happened?" cried Tom quickly.
+
+"It sploded! It done sploded right in mah face!" moaned Eradicate.
+"I--I can't see no mo', Massa Tom! I can't see to help yo' nevah no
+mo'!"
+
+"Don't worry about that, Rad!" cried Tom, as cheerfully as possible
+under the circumstances. "We'll soon have you fixed up! Come in here,
+Koku, and help me carry Rad out!"
+
+Though the fumes from the chemicals that had exploded were choking,
+causing both Tom and Koku to gasp for breath, they never hesitated. In
+they rushed and picked up the limp figure of the helpless colored man.
+
+"Poor Rad!" murmured the giant Koku tenderly. "Him bad hurt! I carry
+him, Master Tom! I take him bed, an' I go for doctor! I run like
+painted pig!"
+
+Probably Koku meant "greased pig," but Tom never thought of that. All
+his concern was for his faithful Eradicate.
+
+"Me carry him, Master Tom!" cried Koku, all the petty jealousy of his
+rival passing away now. "Me take care ob Rad. Him no see, me see for
+him. Anybody hurt Rad now, got to hurt Koku first!"
+
+It was a fine and generous spirit that the giant was showing, though
+Tom had no time to speculate on it just then.
+
+"We must get him into the house, Koku," said the young inventor. "And
+two of us can carry him better than one. After we get him to a bed you
+can go for the doctor, though I fancy the telephone can run even
+quicker than you can, Koku."
+
+"Whatever Master Tom say," returned the giant humbly, as he looked with
+pity at the suffering form of his rival--a rival no longer. It seemed
+that Rad's working days were over.
+
+Tenderly the aged colored man was laid on a lounge in the living room,
+Mr. Swift and Mrs. Baggert hovering over him.
+
+"Where are you worst hurt, Rad?" asked Tom, with a view to getting a
+line on which physician would be the best one to summon.
+
+"It's all in mah face, Massa Tom," moaned the colored man. "It's mah
+eyes. Dat stuff done sploded right in 'em! I can't see--nevah no mo'!"
+
+"Oh, I guess it isn't as bad as that," said Tom. But when he had a
+glimpse of the seared and wounded face of his faithful servant he could
+not repress a shudder.
+
+A physician was summoned by telephone, and he arrived in his automobile
+at the same time that Mr. Damon reached Tom's house.
+
+"Bless my bottle of arnica, Tom!" exclaimed the eccentric man, with
+sympathy in his voice. "What's this I hear? One of your men tells me
+old Eradicate is killed!"
+
+"Not as bad as that, yet," replied Tom, as he came out, leaving the
+doctor to make his first examination. "It was an explosion of my new
+aerial fire-fighting chemicals that I left Rad to mix for me. If
+anything serious results to him from this I'll drop the whole business!
+I'll never forgive myself!"
+
+"It wasn't your fault, Tom. Perhaps he did something wrong," said Mr.
+Damon.
+
+"Yes, it was my fault. I should not have let him take the chance with a
+mixture I had tried only a few times. But we'll hope for the best. How
+is he, Doctor?" Tom asked a little later when the physician came out on
+the porch.
+
+"He's doing as well as can be expected for the present," was the
+answer. "I have given him a quieting mixture. His worst injury seems to
+be to his face. His hands are cut by broken glass, but the hurts are
+only superficial. I think we shall have to get an eye specialist to
+look at him in a day or two."
+
+"You mean that he--that he may go blind?" gasped Tom.
+
+"Well, we'll not decide right away," replied the doctor, as cheerfully
+as he could. "I should rather have the opinion of an oculist before
+making that statement. It may be only temporary."
+
+"That's bad enough!" muttered Tom. "Poor old Rad!"
+
+"Me take care ob him," put in Koku, who had been humbly standing around
+waiting to hear the news. "Me never be mad at dat black man no more!
+Him my best friend! I lub him like I did my brudder!"
+
+"Thank you, Koku," said Tom, and his mind went back to the time when he
+had escaped in his airship from the gigantic men, of whom Koku and his
+brother were two specimens. The brother had gone with a circus, and
+Koku, for several years, only saw him occasionally.
+
+Everything possible was done for Eradicate, and the doctor said that it
+would be several days, until after the burns from the exploding
+chemicals had partly healed, before the eye-doctor could make an
+examination.
+
+"Then we can only wait and hope," said Tom.
+
+"And hope for the best!" advised Mr. Damon.
+
+"I'll try," promised Tom. He went back to the laboratory with his
+eccentric friend and with Ned, who had come over as soon as he heard
+the news. Not much of an examination could be made, as the place was in
+such ruins. But it was surmised that in combining the two chemical
+mixtures a new one had been created, or at least one that Tom had not
+counted on. This had exploded, blowing Eradicate down, flaring a sheet
+of flame up into his face, scattering broken glass about, and generally
+creating havoc.
+
+"I can't understand it," said Tom. "I was trying to make a fire
+extinguishing liquid, and it turned out to be a fire creator. I don't
+see what was wrong."
+
+"One chemical might have been impure," suggested Ned.
+
+"Yes," agreed Tom. "I'll check them over and try to find out where the
+mistake happened."
+
+"This place will have to be rebuilt," observed Ned. "It's in bad shape,
+Tom."
+
+"I don't mind that in the least, if Rad doesn't lose his eyesight," was
+the answer of the young inventor, and his friends could see that he was
+much worried, as well he might be.
+
+In silence Tom Swift looked about the ruins of what had been a fine
+chemical laboratory.
+
+"It will take a month to get this back in shape," he said ruefully. "I
+guess I shall have to postpone my experiments."
+
+"Why not ask Mr. Baxter to help you?" suggested Ned.
+
+"What can he do?" Tom wanted to know. "He hasn't any laboratory."
+
+"He has a sort of one," Ned rejoined. "You know you told me to keep
+track of him and give him any help I could."
+
+"Yes," Tom nodded.
+
+"Well, the other day he came to me and said he had a chance to set up a
+small laboratory in a vacant shop near the river. He needed a little
+capital and I lent it to him, as you told me to."
+
+"Glad you did," returned Tom. "But do you suppose his plant is large
+enough to enable me to work there until mine is in shape again?"
+
+"It wouldn't do any harm to take a look," suggested Ned.
+
+"I'll do it!" decided Tom, more hopefully than he had spoken since the
+accident.
+
+
+
+
+CHAPTER VII
+
+A FORCED LANDING
+
+
+Josephus Baxter seemed to have recovered some of his spirits after his
+narrow escape from death in the fireworks factory blaze. He greeted Tom
+and Ned with a smile as they entered the improvised laboratory he had
+been able to set up in what had once been a factory for the making of
+wooden ware, an industry that, for some reason, did not flourish in
+Shopton.
+
+"I'm glad to see you, Mr. Swift," said the chemist, who seemed to have
+aged several years in the few weeks that had intervened since the fire.
+"I want to thank you for giving me a chance to start over again."
+
+"Oh, that's all right," said Tom easily. "We inventors ought to help
+one another. Are you able to do anything here?"
+
+"As much as possible without my secret formulae," was the answer. "If I
+only had those back from the rascals, Field and Melling, I would be
+able to go ahead faster. As it is, I am working in the dark. For some
+of the formulae were given to me by a Frenchman, and I had only one
+copy. I kept that in the safe of the fireworks concern, and after the
+fire it could not be found."
+
+"Was the safe destroyed?" asked Tom.
+
+"No. But the doors were open, and much of what had been inside was in
+ashes and cinders. Amos Field claimed that the explosion had blown open
+the safe and burned a lot of their valuable fireworks formulae too."
+
+"And you believe they have yours?" asked Ned.
+
+"I'm sure of it!" was the fierce answer. "Those men are unprincipled
+rogues! They had been at me ever since I was foolish enough to tell
+them about my formulae to get me to sell them a share. But I refused,
+for I knew the secret mixtures would make my fortune when I could
+establish a new dye industry. Field and Melling claimed they wanted the
+formulae for their fireworks, but that was only an excuse. The formulae
+were not nearly so valuable for pyrotechnics as for dyes. The fireworks
+business is not so good, either, since so many cities have voted for a
+'Sane Fourth of July.'"
+
+"I can appreciate that," said Tom. "But what we called for, Mr. Baxter,
+is to find if you have room enough to let me do a little experimenting
+here. I am working on a new kind of fire extinguisher, to be dropped on
+tall buildings from an airship."
+
+"Sounds like a good idea," said the chemist, rather dreamily.
+
+"Well, I have the airship, and I can see my way clear to perfecting a
+device to drop the chemicals in metal tanks or bombs," went on Tom.
+"But what bothers me is the chemical mixture that will put out fires
+better than the carbon dioxide mixtures now on the market."
+
+"I haven't given that much study myself," said Mr. Baxter. "But you are
+welcome to anything I have, Mr. Swift. The whole place, such as it is,
+will be at your disposal at any time. I intend to have it in better
+shape soon, but I have to proceed slowly, as I lost nearly everything I
+owned in that fire. If I could only get those formulae back!" he sighed.
+
+"Perhaps you may recall the combinations," suggested Ned. "Or can't you
+get them from that Frenchman?"
+
+"He is dead," answered the chemist. "Everything seems to be against me!"
+
+"Well, it's always darkest just before daylight," said Tom. "So let us
+hope for the best. We both have had a bit of bad luck. But when I think
+of Rad, who may lose his eyesight, I can stand my losses smiling."
+
+"Yes," agreed Mr. Baxter, "you have big assets when you have your
+health and eyesight."
+
+Three days later the eye specialist looked at Rad. Tom stood by
+anxiously and waited for the verdict. The doctor motioned to the young
+inventor to follow him out of the room, while Mrs. Baggert replaced the
+bandages on the colored man's eyes and Koku stood near him,
+sympathetically patting Rad on the back.
+
+"Well?" asked Tom nervously, as he faced the physician.
+
+"I am sorry, Mr. Swift, that I can not hold out much hope that your man
+will ever regain his sight," was the answer.
+
+Tom could not repress a gasp of pity.
+
+"I do not say that the case is altogether hopeless," the doctor went
+on; "but it would be wrong to encourage you to hope for much. I may be
+able to save partly the sight of one eye."
+
+"Poor Rad!" murmured Tom. "This will break his heart."
+
+"There is no need for telling him at once," Dr. Henderson said. "It
+will only make his recovery so much the slower. It will be weeks before
+I am able to operate, and, meanwhile, he should be kept as comfortable
+and cheerful as possible."
+
+"We'll see to that," declared Tom. "Is he otherwise injured?"
+
+"No, it is merely his eyesight that we have to fear for. And, as I
+said, that is not altogether hopeless, though it would not be honest to
+let you look for much success. I shall see him from time to time until
+his eyes are ready to operate on."
+
+Tom and his friends were forced to take such comfort as they could from
+this verdict, but no hint of their downcast feelings were made manifest
+to Eradicate.
+
+"Whut de doctor man done say, Massa Tom?" asked Eradicate when the
+young inventor went back into the sick room.
+
+"Oh, he talked a lot of big Latin words, Rad--bigger words than you
+used to use on your mule Boomerang," and Tom forced a laugh. "All he
+meant was that you'd have to stay in bed a while and let Koku wait on
+you."
+
+"Huh! Am dat--dat big--dat big nice man heah now?" asked Rad, feeling
+around with his bandaged hand; and a smile showed beneath the cloth
+over his eyes.
+
+"I here right upsidedown by you, Rad," said Koku, and his big hand
+clasped the smaller one of the black man.
+
+"Koku--yo'--yo' am mighty good to me," murmured Eradicate. "I reckon I
+been cross to yo' sometimes, but I didn't mean nuffin' by it!"
+
+"Huh! me an' you good friends now," said the giant. "Anybody what hurt
+my Rad, I--I--bust 'im! Dat I do!" cried the big fellow.
+
+"Come on," whispered Tom to Ned. "They'll get along all right together
+now."
+
+But Eradicate caught the sound of his young employer's footsteps and
+called:
+
+"Yo' goin', Massa Tom?"
+
+"Yes, Rad. Is there anything you want?"
+
+"No, Massa Tom. I jest wanted to ast if yo' done 'membered de time mah
+mule Boomerang got stuck in de road, an' yo' couldn't git past in yo'
+auto? Does yo' 'member dat?"
+
+"Indeed I do!" laughed Tom, and Eradicate also chuckled at the
+recollection.
+
+"That laugh will do him more good than medicine," declared the doctor,
+as he took his leave. "I'll come again, when I can make a more thorough
+examination," he added.
+
+For Tom the following days, that lengthened into weeks, were anxious
+ones. There was a constant worry over Eradicate. Then, too, he was
+having trouble with his latest invention--his aerial fire-fighting
+apparatus. It was not that Tom was financially dependent on this
+invention. He was wealthy enough for his needs from other patented
+inventions he and his father owned.
+
+But Tom Swift was a lad not easily satisfied. Once embarked on an
+enterprise, whether it was the creation of a gigantic searchlight, an
+electric rifle, a photo telephone or a war tank, he never rested until
+he had brought it to a successful consummation.
+
+But there was something about this chemical fire extinguishing mixture
+that defied the young inventor's best efforts. Mixture after mixture
+was tried and discarded. Tom wanted something better than the usual
+carbonate and sulphuric combination, and he was not going to rest until
+he found it.
+
+"I think you've struck a blind lead, Tom," said Ned, more than once.
+
+"Well, I'm not going to give up," was the firm answer.
+
+"Bless my shoe laces!" cried Mr. Damon, when he had called on Tom once
+at the Baxter laboratory and had been driven out, holding his breath,
+because of the chemical fumes, "I should think you couldn't even start
+a fire with that around, Tom, much less need to put one out."
+
+"Well, it doesn't seem to work," said the young inventor ruefully.
+"Everything I do lately goes wrong."
+
+"It is that way sometimes," said Mr. Baxter. "Suppose you let me study
+over your formulae a bit, Mr. Swift. I haven't given much thought to
+fire extinguishers, but I may be able, for that very reason, to
+approach the subject from a new angle. I'll lay aside my attempt to get
+back the lost formulae and help you."
+
+"I wish you would!" exclaimed Tom eagerly. "My head is woozie from
+thinking! Suppose I leave you to yourself for a time, Mr. Baxter? I'll
+go for an airship ride."
+
+"Yes, do," urged the chemist. "Sometimes a change of scene is of
+benefit. I'll see what I can do for you."
+
+"Will you come along, Ned--Mr. Damon?" asked Tom, as he prepared to
+leave the improvised laboratory, the repairs on his own not yet having
+been finished.
+
+"Thank you, no," answered Ned. "I have some collections to make."
+
+"And I promised my wife I'd take her riding, Tom," said the jolly,
+eccentric man. "Bless my umbrella! she'd never forgive me if I went off
+with you. But I'll run you to your first stopping place, Ned, and you
+to your hangar, Tom."
+
+His invitation was accepted, and, in due season, Tom was soaring aloft
+in one of his speedy cloud craft.
+
+"Guess I'll drop down and get Mary Nestor," he decided, after riding
+about alone for a while and finding that the motor was running sweetly
+and smoothly. "She hasn't been out lately."
+
+Tom made a landing in a field not far from the home of the girl he
+hoped to marry some day, and walked over to her house.
+
+"Go for a ride? I just guess. I will!" cried Mary, with sparkling eyes.
+"Just wait until I get on my togs."
+
+She had a leather suit, as had Tom, and they were soon in the machine,
+which, being equipped with a self-starter, did not need the services of
+a mechanician to whirl the propellers.
+
+"Oh, isn't it glorious!" said Mary, as she sat at Tom's side. They
+were in a little enclosed cabin of the craft--which carried just
+two--and, thus enclosed, they could speak by raising their voices
+somewhat, for the noise of the motor was much muffled, due to one of
+Tom's inventions.
+
+Other rides on other days followed this one, for Tom found more rest
+and better refreshment after his hours of toil and study in these rides
+with Mary than in any other way.
+
+"I do love these rides, Tom!" the girl cried one day when the two were
+soaring aloft. "And this one I really believe is better than any of the
+rest. Though I always think that," she added, with a slight laugh.
+
+"Glad you like it," Tom answered, and there was something in his voice
+that caused Mary to look curiously at him.
+
+"What's the matter, Tom?" she asked. "Has anything happened? Is Rad's
+case hopeless?"
+
+"Oh, no, not yet. Of course it isn't yet sure that he will ever see
+again, but, on the other hand, it isn't decided that he can't. It's a
+fifty-fifty proposition."
+
+"But what makes you so serious?"
+
+"Was I?"
+
+"I should say so! You haven't told me one funny thing that Mr. Damon
+has said lately."
+
+"Oh, haven't I? Well, let me see now," and he sent the machine up a
+little. "Well, the other day he--"
+
+Tom suddenly stopped speaking and began rapidly turning several valve
+wheels and levers.
+
+"What--what's the matter?" gasped Mary, but she did not clutch his arm.
+She knew better than that.
+
+"The motor has stopped," Tom answered, and the girl became aware of a
+cessation of the subdued hum.
+
+"Is it--does it mean danger?" she asked.
+
+"Not necessarily so," Tom replied. "It means we have to make a forced
+landing, that's all. Sit tight! We're going down rather faster than
+usual, Mary, but we'll come out of it all right!"'
+
+
+
+
+CHAPTER VIII
+
+STRANGE TALK
+
+
+There was a rapid and sudden drop. Mary, sitting beside Tom Swift in
+the speedy aeroplane, watched with fascinated eyes as he quickly
+juggled with levers and tried different valve wheels. The girl, through
+her goggles, had a vision of a landscape shooting past with the speed
+of light. She glimpsed a brook, and, almost instantly, they had skimmed
+over it.
+
+A jar, a nerve-racking tilt to one side, the creaking of wood and the
+rattle of metal, a careening, and then the machine came to a stop, not
+exactly on a level keel, but at least right side up, in the midst of a
+wide field.
+
+Tom shut off the gas, cut his spark, and, raising his goggles, looked
+down at Mary at his side.
+
+"Scared?" he asked, smiling.
+
+"I was," she frankly admitted. "Is anything broken, Tom?"
+
+"I hope not," answered the young inventor. "At least if it is, the
+damage is on the under part. Nothing visible up here. But let me help
+you out. Looks as if we'd have to run for it."
+
+"Run?" repeated Mary, while proving that she did not exactly need help,
+for she was getting out of her seat unaided. "Why? Is it going to catch
+fire?"
+
+"No. But it's going to rain soon--and hard, too, if I'm any judge," Tom
+said. "I don't believe I'll take a chance trying to get the machine
+going again. We'll make for that farmhouse and stay there until after
+the storm. Looks as if we could get shelter there, and perhaps a bit to
+eat. I'm beginning to feel hungry."
+
+"It is going to rain!" decided Mary, as Tom helped her down over the
+side of the fusilage. "It's good we are so near shelter."
+
+Tom did not answer. He was making a hasty but accurate observation of
+the state of his aeroplane. The landing wheels had stood the shock
+well, and nothing appeared to be broken.
+
+"We came down rather harder than I wanted to," remarked Tom, as he
+crawled out after his inspection of the machine. "Though I've made
+worse forced landings than that."
+
+"What caused it?" asked Mary, glancing up at the clouds, which were
+getting blacker and blacker, and from which, now and then, vivid
+flashes of lightning came while low mutterings of thunder rolled nearer
+and nearer. "Something seemed to be wrong with the carburetor," Tom
+answered. "I won't try to monkey with it now. Let's hike for that
+farmhouse. We'll be lucky if we don't get drenched. Are you sure you're
+all right, Mary?"
+
+"Certainly, Tom. I can stand a worse shaking up than that. And you
+needn't think I can't run, either!"
+
+She proved this by hastening along at Tom's side. And there was need of
+haste, for soon after they left the stranded aeroplane the big drops
+began to pelt down, and they reached the house just as the deluge came.
+
+"I don't know this place, do you, Tom?" asked Mary, as they ran in
+through a gateway in a fence that surrounded the property. A path
+seemed to lead all around the old, rambling house, and there was a
+porch with a side entrance door. This, being nearer, had been picked
+out by the young inventor and his friend.
+
+"No, I don't remember being here before," Tom answered. "But I've
+passed the place often enough with Ned and Mr. Damon. I guess they
+won't refuse to let us sit on the porch, and they may be induced to
+give us a glass of milk and some sandwiches--that is, sell them to us."
+
+He and Mary, a little breathless from their run, hastened up on the
+porch, slightly wet from the sudden outburst of rain. As Tom knocked on
+the door there came a clap of thunder, following a burst of lightning,
+that caused Mary to put her hands over her ears.
+
+"Guess they didn't hear that," observed Tom, as the echoes of the blast
+died away. "I mean my knock. The thunder drowned it. I'll try again."
+
+He took advantage of a lull in the thundering reverberations, and
+tapped smartly. The door was almost at once opened by an aged woman,
+who stared in some amazement at the young people. Then she said:
+
+"Guests must go to the front door."
+
+"Guests!" exclaimed Tom. "We aren't exactly guests. Of course we'd like
+to be considered in that light. But we've had an accident--my aeroplane
+stopped and we'd like to stay here out of the storm, and perhaps get
+something to eat."
+
+"That can be arranged--yes," said the old woman, who spoke with a
+foreign accent. "But you must go to the front door. This is the
+servant's entrance."
+
+Mary was just thinking that they used considerable formality for casual
+wayfarers, when the situation dawned on Tom Swift.
+
+"Is this a restaurant--an inn?" he asked.
+
+"Yes," answered the old woman. "It is Meadow Inn. Please go to the
+front door."
+
+"All right," Tom agreed good-naturedly. "I'm glad we struck the place,
+anyhow."
+
+The porch extended around three sides of the old, rambling house.
+Proceeding along the sheltered piazza, Tom and Mary soon found
+themselves at the front door. There the nature of the place was at once
+made plain, for on a board was lettered the words "Meadow Inn."
+
+"I see what has happened," Tom remarked, as he opened the old-fashioned
+ground glass door and ushered Mary in. "Some one has taken the old
+farmhouse and made it into a roadhouse--a wayside inn. I shouldn't
+think such a place would pay out here; but I'm mighty glad we struck
+it."
+
+"Yes, indeed," agreed Mary.
+
+The old farmhouse, one of the best of its day, had been transformed
+into a roadhouse of the better class. On either side of the entrance
+hall were dining rooms, in which were set small tables, spread with
+snowy cloths.
+
+"In here, sir, if you please," said a white-aproned waiter, gliding
+forward to take Tom's leather coat and Mary's jacket of like material.
+The waiter ushered them into a room, in which at first there seemed to
+be no other diners. Then, from behind a screen which was pulled around
+a table in one corner, came the murmur of voices and the clatter of
+cutlery on china, which told of some one at a meal there.
+
+"Somebody is fond of seclusion," thought Tom, as he and Mary took their
+places. And as he glanced over the bill of fare his ears caught the
+murmur of the voices of two men coming from behind the screen. One
+voice was low and rumbling, the other high-pitched and querulous.
+
+"Talking business, probably," mused Tom. "What do you feel like
+eating?" he asked Mary.
+
+"I wasn't very hungry until I came in," she answered, with a smile.
+"But it is so cozy and quaint here, and so clean and neat, that it
+really gives one an appetite. Isn't it a delightful place, Tom? Did you
+know it was here?"
+
+"It is very nice. And as this is the first I have been here for a long
+while I didn't know, any more than you, that it had been made into a
+roadhouse. But what shall I order for you?"
+
+"I should think you would have had enough experience by this time,"
+laughed Mary, for it was not the first occasion that she and Tom had
+dined out.
+
+Thereupon he gave her order and his own, too, and they were soon eating
+heartily of food that was in keeping with the appearance of the place.
+
+"I must bring Ned and Mr. Damon here," said Tom. "They'll appreciate
+the quaintness of this inn," for many of the quaint appointments of the
+old farmhouse had been retained, making it a charming resort for a meal.
+
+"Mr. Damon will like it," said Mary. "Especially the big fireplace,"
+and she pointed to one on which burned a blaze of hickory wood. "He'll
+bless everything he sees."
+
+"And cause the waiter to look at me as though I had brought in an
+escaped inmate from some sanitarium," laughed Tom. "No use talking, Mr.
+Damon is delightfully queer! Now what do you want for dessert?"
+
+"Let me see the card," begged Mary. "I fancy some French pastry, if
+they have it."
+
+Tom gazed idly but approvingly about as she scanned the list. The
+sound of the rumbling and the higher-pitched voices had gone on
+throughout the entire meal, and now, as comparative silence filled the
+room, the clatter of knives and forks having ceased, Tom heard more
+clearly what was being said behind the screen.
+
+"Well, I tell you what it is," said the man whom Tom mentally dubbed
+Mr. High. "We got out of that blaze mighty luckily!"
+
+"Yes," agreed he of the rumbly voice, whom Tom thought of as Mr. Low,
+"it was a close shave. If it hadn't been for his chemicals, though,
+there would have been a cleaner sweep."
+
+"Indeed there would! I never knew that any of them could act as fire
+extinguishers."
+
+Tom seemed to stiffen at this, and his hearing became more acute.
+
+"They aren't really fire extinguishers in the real sense of the word,"
+went on the other man behind the screen. "It must have been some
+accidental combination of them. But in spite of that we put it all over
+Josephus Baxter in that fire!"
+
+"What's this? What's this?" thought Tom, shooting a glance at Mary and
+noting that apparently she had not heard what was said. "What strange
+talk is this?"
+
+
+
+
+CHAPTER IX
+
+SUSPICIONS
+
+
+"What's that?" exclaimed Mary Nestor, giving such a start as she sat
+opposite Tom at the restaurant table that she dropped the bill of fare
+she had been looking over.
+
+A crash had resounded through the room, but it spoke well for the state
+of Tom's nerves that he gave no indication that he had heard the noise.
+It was caused by a waiter when he dropped a plate, which was smashed
+into pieces on the floor. The noise was startling enough to excuse Mary
+for jumping in her chair, and it seemed to put an end to the strange
+talk of "Mr. High" and "Mr. Low" back of the screen, for after the
+crash of china only indistinct murmurs came from there. But Tom Swift
+did not cease to wonder at the import of the talk about chemicals,
+fire, and the mention of the name of Josephus Baxter.
+
+"I think I'll try some of those Murolloas, as they call them, Tom,"
+announced Mary, having made her selection of the pastry. "And may I
+have another cup of tea?"
+
+"Two if you like," answered the young inventor. "They say tea is good
+for the nerves, and you seem to need something, judging by the way you
+jumped when that plate fell."
+
+"Oh, Tom, that isn't fair! After the way we had to come down in your
+'plane!" objected Mary.
+
+"That's right!" he conceded. "I forgot about that. My fault, entirely!"
+
+Mary smiled, and seemed to have regained her composure. Tom glanced at
+her anxiously, not because of what he thought might be the state of her
+nerves, but to see if she had sensed anything the two men behind the
+screen had said. But the girl gave no indication that her mind had been
+occupied with anything more than the selection of her dessert.
+
+"I wonder who they are, and what they meant by that talk," mused Tom,
+as the waiter served the Murolloas to him and Mary. "Poor Baxter! It
+looks as if he might have more enemies than the fireworks men he
+accuses of having taken his valuable formulae. I must see him soon, and
+have a talk with him. Yes, I must make a special point to see Josephus
+Baxter. But first I'd like to have a glimpse of these men."
+
+Tom's wish in this respect was soon gratified, for before he and Mary
+had finished their pastry and tea there was a scraping of chairs back
+of the sheltering screen, and the two men, "Mr. Low" and "Mr. High,"
+who had finished their meal, came forth.
+
+Tom's judgment as to the statures of the men, based on the quality of
+their voices, was not exactly borne out. For it was the big man who had
+the high pitched, squeaky voice, and the little man who had the deep,
+rumbling tones.
+
+They passed out, without more than a glance at Tom and his companion,
+but the young inventor peered at them sharply. As far as he could tell
+he had seen neither of them before, though he had an idea of their
+identity.
+
+Tom took the chance to make certain this conjecture when Mary left her
+seat, announcing that she was going to the ladies' parlor to arrange
+her hair, which the run to escape from the rain had disarranged.
+
+"Some storm," Tom observed to the waiter, who came up when the young
+inventor indicated that he wanted his check.
+
+"Yes, sir, it came suddenly. Hope you didn't have to change a tire in
+it, sir."
+
+"No, my machine isn't that kind," replied Tom, as he handed out a
+generous tip. "If I need a new tire I generally need a whole new
+outfit."
+
+"Oh, then--" Obviously the man was puzzled.
+
+"We came in an aeroplane," Tom explained. "But we had to make a forced
+landing. Is there a garage near here? I may need some help getting
+started."
+
+"We accommodate a few cars in what was once the barn, and we have a
+good mechanic, sir. If you'd like to see him--"
+
+"I would," interrupted Tom. "Tell the young lady to wait here for me.
+I'll see if I can get the Scud to work. If not, I'll have to telephone
+to town for a taxi. Did those men who just left come in a car?" and he
+nodded in the direction taken by the two who had dined behind the
+screen.
+
+"Yes, sir. And they had engine trouble, I believe. Our man fixed up
+their machine."
+
+"Then he's the chap I want to see," thought Tom. "I'll have a talk with
+him." He reasoned that he could get more about the identity of the two
+mysterious men from the mechanic than from the waiter. Nor was he wrong
+in this surmise.
+
+"Oh, them two fellers!" exclaimed the mechanician, after he had agreed
+to go with Tom to where the airship Scud was stalled. "They come from
+over Shopton way. They own a fireworks factory--or they did, before it
+burned."
+
+"Are they Field and Melling?" asked Tom, trying not to let any
+excitement betray itself in his voice.
+
+"That's the names they gave me," said the man. "Little man's Field. He
+gave me his card. I'm going to get a job overhauling his car. There
+isn't enough work here to keep a man busy, and I told 'em I could do a
+little on the outside. This place just started, and not many folks know
+about it yet."
+
+"So I judge," Tom said. "Well, I'll be glad to have you give me a hand.
+I fancy the carburetor is out of order."
+
+And this, when the young inventor and the mechanician from Meadow Inn
+reached the stranded Scud, was found to be the case. The storm had
+passed, and Mary told Tom she would not mind waiting at the Inn until
+he found whether or not he could get his air craft in working order.
+
+"There you are! That's the trouble!" exclaimed the mechanician, as he
+took something out of the carburetor. "A bit of rubber washer choked
+the needle valve."
+
+"Glad you found it," said Tom heartily. "Now I guess we can ride back."
+
+While preparations were being made to test the Scud after the
+carburetor had been reassembled, Tom's mind was busy with many
+thoughts, and chief among them were suspicions concerning Field and
+Melling.
+
+"If their talk meant anything at all," reasoned the young inventor, "it
+meant that there was some deal in which Josephus Baxter got the worst
+of it. 'Putting it over on him in the fire,' could only mean that. Of
+course it isn't any of my business, in a way, but I don't think it is
+right to stand by and see a fellow inventor defrauded.
+
+"Of course," mused Tom, while his helper put the finishing touches to
+the carburetor, "it may have been a business deal in which one took as
+many chances as the other. There are always two sides to every story.
+Baxter says they took his formulae, but he may have taken something
+from them to make it even. The only thing is that I'd trust Baxter
+sooner than I would those two fellows, and he certainly had a narrow
+squeak at the fire.
+
+"But I have my own troubles, I guess, trying to perfect that
+fire-fighting chemical, and I haven't much time to bother with Field
+and Melling, unless they come my way."
+
+"There, I reckon she'll work," said the mechanician, as he fastened the
+last valve in the carburetor. "It was an easier job than I expected.
+Wasn't as much trouble as I had over their car those two fellers you
+were speaking of--Field and Melling. They're rich guys!"
+
+"Yes?" replied Tom, questioningly.
+
+"Sure! They've started a big dye company."
+
+"A dye company?" repeated the young inventor, all his suspicions coming
+back as he recalled that Baxter had said his formulae were more
+valuable for dyes than for fireworks.
+
+"Yes, they're trying to get the business that used to go to the Germans
+before the war," went on the man.
+
+"Yes, the Germans used to have a monopoly of the dye industry," said
+Tom, hoping the man would talk on. He need not have worried. He was of
+the talkative type.
+
+"Well, if these fellers have their way they'll make a million in dyes,"
+proceeded the mechanician, as he stepped down out of the airship.
+"They've built a big plant, and they have offices in the Landmark
+Building."
+
+"Where's that?" asked Tom.
+
+"Over in Newmarket," the man went on, naming the nearest large city to
+Shopton. "The Landmark Building is a regular New York skyscraper.
+Haven't you seen it?"
+
+"No," Tom answered, "I haven't. Been too busy, I guess. So Field and
+Melling have their offices there?"
+
+"Yes, and a big plant on the outskirts for making dyes. They half
+offered me a job at the factory, but I thought I'd try this out first;
+I like it here."
+
+"It is a nice place," agreed Tom. "Well, now let's see if she'll work,"
+and he nodded at the Scud.
+
+It needed but a short test to demonstrate this and soon Tom went back
+to the Inn for Mary.
+
+"Are you sure we shall not have to make another forced landing?" she
+asked with a smile, a she took her place in the cockpit.
+
+"You can't guarantee anything about an aeroplane," said Tom. "But
+everything is in our favor, and if we do have to come down I have a
+better landing field than this." He glanced over the meadow near the
+wayside inn.
+
+"I suppose I'll have to take a chance," said Mary.
+
+However, neither of them need have worried, for the Scud tried,
+evidently, to redeem herself, and flew back to Shopton without a hitch.
+After making sure that his engine was running smoothly, Tom found his
+mind more at ease, and again he caught himself casting about to find
+some basis for his suspicious thoughts regarding the two men who had
+talked behind the screen.
+
+"What is their game?" Tom found himself asking himself over and over
+again. "What did they 'put over' on poor Baxter?"
+
+Tom had a chance to find out more about this, or at least start on the
+trail sooner than he expected. For when he landed he saw Koku, the
+giant, coming toward him with an appearance of excitement.
+
+"Is Rad worse? Is there more trouble with his eyes?" asked the young
+inventor.
+
+"No, him not much too bad," answered Koku. "I keep him good as I can.
+He sleep now, so I come out to swallow some fresh air. But man come to
+see you--much mad man."
+
+"Mad?" queried Tom.
+
+"Well, what you say--angry," went on Koku. "Man what was in Roman
+Skycracker blaze."
+
+"Oh, you mean Mr. Baxter, who was in the fireworks blaze," translated
+Tom. "Where is he, and what's the matter?"
+
+
+
+
+CHAPTER X
+
+ANOTHER ATTEMPT
+
+
+Koku managed to make Tom understand that the dye inventor was in the
+main office of the Swift plant talking to Tom's father. The young
+inventor sent Mary home in his electric runabout in company with Ned
+Newton, who, fortunately, happened along just then, and hurried to his
+office.
+
+"Oh, Tom, I'm glad you have arrived," said his father. "You remember
+Mr. Baxter, of course."
+
+"I should hope so," Tom answered, extending his hand. He noticed that
+the man whom he had helped save from the fireworks blaze was under the
+stress of some excitement.
+
+"I hope he hasn't been getting on dad's nerves," thought Tom, as he
+took a seat. The elder Mr. Swift had been quite ill, and it was thought
+for a time that he would have to give up helping Tom. But there had
+been a turn for the better, and the aged inventor had again taken his
+place in the laboratory, though he was frail.
+
+"What's the trouble now?" asked Tom. "At least I assume there has been
+some trouble," he went on. "If I am wrong--"
+
+"No, you are right, unfortunately," said Mr. Baxter gloomily. "The
+trouble is that everything I do is a failure. Up to a little while ago
+I thought I might succeed, in spite of Field and Melling's theft of the
+formulae from me. I made a purple dye the other day, and tested it
+today. It was a miserable failure, and it got on my nerves. I came to
+see if you could help me."
+
+"In what way?" asked Tom, wondering whether or not he had best tell Mr.
+Baxter what he had overheard at the Inn.
+
+"Well, I need better laboratory facilities," the man went on. "I know
+you have been very kind to me, Mr. Swift, and it seems like an
+imposition to ask for more. But I need a different lot of chemicals,
+and they cost money. I also need some different apparatus. You have it
+in your big laboratory. That wouldn't cost you anything. But of course
+to go out and buy what I need--"
+
+"Oh I guess we can stand that, can't we, Dad?" asked Tom, with a genial
+smile. "You may have free access to our big laboratory, Mr. Baxter, and
+I'll see that you get what chemicals you need."
+
+"Oh, thank you!" exclaimed the inventor. "Now I believe I shall succeed
+in spite of those rascals. Just think, Mr. Swift! They have started a
+big new dye factory."
+
+"So I have heard," replied Tom.
+
+"And I'm almost sure they're using the secret formulae they stole from
+me!" exclaimed Mr. Baxter. "But I'll get the best of them yet! I'll
+invent a better dye than they ever can, even if they use the secrets
+the old Frenchman gave me. All I need is a better place to work and all
+the chemicals at my disposal."
+
+"Then we'll try to help you," offered Tom.
+
+"And if I can do anything let me know," put in Mr. Swift. "I shall be
+glad to get in the harness again, Tom!" he added.
+
+"Well, if you're so anxious to work, Dad, why not give me a hand with
+my fire extinguisher chemical?" asked Tom. "I haven't been able to hit
+on the solution, somehow or other."
+
+"Perhaps I may be able to give you a hint or two after I get settled
+down," suggested Mr. Baxter.
+
+"I shall be glad of any assistance you can give," replied Tom Swift.
+"And now I'm going to start right in. Dad, you can make the
+arrangements for Mr. Baxter to use our big laboratory. And let him have
+credit for any chemicals he needs. Have them put on my bill, for I am
+buying a lot myself."
+
+"I'll never forget this," said Mr. Baxter, and there were tears in his
+eyes as he shook hands with Tom, who tried to make light of his
+generous act.
+
+Tom, after the wrecking of his laboratory, in which accident poor
+Eradicate was injured, had built himself another--two others, in fact,
+after having shared Mr. Baxter's temporary one for a time. Tom put up
+the most completely equipped laboratory that could be devised, and he
+also erected a smaller one for his own personal use, the main one being
+at the disposal of his father and the various heads of the different
+departments of the Shopton plant.
+
+The little conference broke up, and Tom was on his way to his own
+special private laboratory when there came the sound of some excitement
+in the corridor outside and Mr. Damon burst in.
+
+"Bless my accident policy, Tom! what's this I hear?" he asked, all in a
+fluster.
+
+"I'm sure I don't know," answered the young inventor, with a smile.
+"What about?"
+
+"About you and Mary Nestor being killed!" burst out Mr. Damon. "I
+heard you fell in the aeroplane and were both dashed to pieces!"
+
+"If you can believe the evidence of your own eyes, I'm far from being
+in that state," laughed Tom. "And as for Mary, she just left here with
+Ned Newton."
+
+"Thank goodness!" sighed Mr. Damon, sinking into a chair. "Bless my
+elevator! I rushed over as soon as I heard the news, and I was almost
+afraid to come in. I'm so glad it didn't happen!"
+
+"No gladder than I," said Tom. "We had to make a forced landing, that
+was all," and he made as light of the incident as possible when he saw
+the look of terror in his father's eyes.
+
+"Some people in Waterford saw you going down," went on Mr. Damon, "and
+they told me."
+
+"It was a false alarm," replied Tom. "And now, Mr. Damon, if you want
+to smell some perfumes come with me."
+
+"Are you going into that line, Tom?" asked the eccentric man. "Bless
+my handkerchief, my wife will be glad of that!"
+
+"I mean I'm going to experiment some more with fire-extinguishing
+chemicals," laughed the young inventor. "If you want to--"
+
+"Bless my gas mask, I should say not!" cried Mr. Damon. "I don't see
+how you stand those odors, Tom Swift."
+
+"Guess I'm used to 'em," was the answer. And then, leaving his father
+to entertain Mr. Damon and to make arrangements for Mr. Baxter's use of
+the main laboratory, he betook himself to his own private quarters.
+
+The next week or so was a busy time for Tom; so busy, in fact, that he
+had little chance to see Mr. Baxter. All he knew was that the
+unfortunate man was also laboring in his own line, and Tom wished him
+success. He knew that if the man made any discoveries that would help
+with the fire-extinguishing fluid he would report, as he had promised.
+
+"Well, Tom, how goes it?" asked Ned one day when he came over to call
+on his chum. "Are you ready to accept contracts for putting out
+skyscraper blazes in all big cities?"
+
+"Not yet," was the answer. "But I'm going to make another attempt, Ned."
+
+"You mean another experiment?"
+
+"Yes, I have evolved a new combination of chemicals, using something of
+the carbonate idea as a basis. I found that I couldn't get away from
+that, much as I wanted to. But my application is entirely new, at least
+I hope it will prove so."
+
+"When are you going to try it?" asked Ned.
+
+"Right away. All I have to do is to put the chemicals in the metal
+tank."
+
+"Then I'd better get my leather suit on," remarked Ned, starting to
+take off his street coat. Tom kept for his chum a full outfit of flying
+garments, one suit being electrically heated.
+
+"Oh, we aren't going up in any airship," Tom said.
+
+"Why, I thought you were going to test your aerial fire fighting
+dingus!" exclaimed Ned.
+
+"So I am. But I want to stay on the ground and watch the effect on the
+blaze as the tank bursts and scatters the chemical fluid."
+
+"Then you want me, and perhaps Mr. Damon to take the stuff up in the
+machine? Excuse me. I don't believe I care to run an airship myself."
+
+"No," went on Tom, "there isn't any question of an airship this time.
+No one is going up. Come on out into the yard and I'll show you."
+
+Ned Newton followed his chum out into the big yard near one of the
+shops. Erected in it, and evidently a new structure, was a large wooden
+scaffold in square tower shape with a long overhanging arm and a
+platform on the extremity. Beneath it was a pit dug in the earth, and
+in this pit, which was directly under the outstanding arm of the tower,
+was a pile of wood and shavings, oil-soaked.
+
+"Oh, I see the game," remarked Ned. "You're going to drop the stuff
+from this height instead of doing it from an airship."
+
+"Yes," Tom answered. "There will be time enough to go on with the
+airship end of it after I get the right combination of chemicals. And
+by having a metal container with the stuff in dropped from this frame
+work, I can station myself as near the burning pit as I can get and
+watch what happens."
+
+"It's a good idea," decided Ned. "I wonder you didn't try that before."
+
+"Mr. Baxter suggested it," replied Tom. "That helpful idea more than
+pays me for what I have done for him. So now, if you're ready, I'd like
+to have you watch with me and make some notes, one of us on one side of
+the pit, and one on the other. There are always two sides to a fire,
+the leeward and the windward, and I want to see how my chemicals act in
+both positions."
+
+"I'm with you," said Ned. "Who's going to drop the stuff--Koku?"
+
+"No, he is a bit too heavy for the framework, which I had put up in a
+hurry. I'd have Rad do it, but he's out of the game."
+
+"Poor old Rad!" murmured Ned. "Do you think he'll ever get better, Tom?"
+
+"I don't know," sighed the young inventor. "All I can do is to hope. He
+is very patient, and Koku is devoted to him. All their little
+bickerings and squabbles seem to have been forgotten."
+
+Tom called some of his workmen, some of them to start the blaze of
+inflammable material in the pit, while one climbed up to the top of the
+tower of scantlings and made his way out on the extended arm, where
+there was a little platform for him to stand until it was time to drop
+the chemicals.
+
+"Light her up!" cried Tom Swift, and a match was thrown in among the
+oiled wood. In an instant a fierce blaze shot up, as hot, in
+proportion, as would come from any burning building.
+
+For the second time Tom was about to make a test on a fairly large
+scale of his experimental extinguisher mixture.
+
+"All ready up there?" he called to his helper perched high in the air.
+
+"All ready!" came back the answer above the roar and crackle of the
+flames that made Tom and Ned step back.
+
+Would success or failure attend the young inventor's project?
+
+
+
+
+CHAPTER XI
+
+THE BLAZING TREE
+
+
+Tom Swift hesitated a moment before giving the final word that would
+send the metal container of powerful chemicals down into the midst of
+the crackling flames. He wanted to make sure, in his own mind, that he
+had done everything possible to insure the success of his undertaking.
+The young inventor never attempted the solution of any problem without
+going into it with his whole energy. So he wanted this experiment to
+succeed.
+
+He quickly reviewed, mentally, the composition of the chemical
+compound. He had made it as strong as possible, and he had spared no
+pains to insure a hot fire, so that the test would not be too simple.
+
+"What's the matter, Tom?" asked Ned, as his chum appeared to hesitate
+about giving the word that would send the chemicals hurtling down into
+the fire.
+
+"Nothing. I was just making sure I hadn't forgotten anything," Tom
+answered. "I guess I haven't."
+
+He paused a moment, looked up at his assistant on the overhanging arm
+of the tower, glanced down at the flames, now at their height, and then
+suddenly cried:
+
+"Let her go!"
+
+"Right!" came back the man's voice, and then a dark object, like a
+bomb, was seen descending from the skeleton framework above the flames.
+
+There was a scattering of the fire in the pit as the extinguisher bomb
+fell among the blazing embers. Then followed a slight explosion when
+the bomb broke, as it was intended it should.
+
+Tom and Ned leaned forward to peer through the pall of smoke which
+swirled this way and that. Here was to come the real test of the
+device. Would the fumes of the liberated chemicals choke the fire, or
+would it burn on in spite of them? That was the question to be settled
+for Tom Swift.
+
+Almost immediately he had his answer. For after a fierce burst of the
+tongues of fire following the fall of the bomb, there was a distinct
+dying down of the conflagration in the pit. Great clouds of smoke
+arose, but the fire was quenched in a great measure, and as the
+fire-blanketing gas continued to be generated from the chemicals
+liberated from the bomb, there was a further dying down of the
+crackling fire.
+
+"Tom, you've struck it!" yelled Ned in delight. "You have the right
+combination this time!"
+
+Tom did not answer. He leaned forward and looked eagerly down into the
+pit. He was about to join with Ned in agreeing that he had, indeed,
+solved the problem, when, to his surprise, the flames started up again.
+
+"What's this?" asked the young financial manager. "Are you going to
+have a second test, Tom?"
+
+"Not that I know of," was the puzzled answer. "I don't exactly
+understand this myself, Ned. By all calculations this fire ought to
+have died a natural death, but now it is breaking out again. I think
+what must have happened is that a quantity of the oil they poured on
+collected in a pool and didn't get all the effects of the chemicals
+from the bomb. Then the oil started to blaze."
+
+"What can you do about it?" Ned wanted to know.
+
+"Oh, I've got another bomb up there," and Tom pointed to his helper who
+was still perched on the overhanging arm. "I was prepared for some such
+emergency as this. Drop the other one!" Tom yelled, and again a dark
+object fell, bursting in the pit and again liberating the gas that was
+supposed to choke any fire.
+
+The flames that had started up for the second time instantly died down,
+and Ned, leaning over the edge of the pit, cried:
+
+"Hurray, Tom! That does the business!" But the young inventor shook his
+head. "I'm not quite satisfied," he remarked. "It didn't work quickly
+enough. What I want is a chemical combination that will choke the fire
+off first shot."
+
+"Well, you pretty nearly have it," observed Ned.
+
+"Yes. But 'good enough' isn't what I want," Tom said. "I've got to work
+on that chemical compound again. I think I know where I can improve it."
+
+"Well, if I were a fire, and I had this happen to me," remarked Ned,
+laughing and pointing to the heap of blackened embers in the pit, "I
+should feel very much discouraged."
+
+"But not enough," declared Tom. "I want the fire to be out more quickly
+than this one was. I think I can improve that chemical compound, and
+I'm going to do it."
+
+"All right! Come on down!" he called to his helper, who was still
+perched on the overhanging arm. "We won't do any more today."
+
+"What is your next move?" asked Ned, as Tom started for his small,
+private laboratory.
+
+"Oh, I'm going to fiddle around among those sweet-smelling chemicals,"
+answered the young inventor.
+
+"Bless my vest buttons! then I'm not coming in, exclaimed a voice which
+could proceed from none other than Mr. Damon. And he it proved to be.
+He had driven over from Waterford in his automobile and had arrived
+just as the fire test was concluded.
+
+"Oh, come on in!" called Tom. "You can visit with dad, and Eradicate
+will be glad to see you."
+
+"Poor Rad! How is he?" asked Mr. Damon, walking along with Tom and Ned.
+
+"No change," was the sad answer of the young inventor, for he felt
+responsible for the mishap to the colored man. "They can't operate on
+his eyes yet."
+
+"And when they do will he be able to see?" asked Mr. Damon.
+
+"That is what we are all hoping," answered Tom with a sigh. "But do go
+in to see him, Mr. Damon. It will cheer him up."
+
+"I will," promised the eccentric man. "At any rate I'll not venture
+near your perfume shop, Tom Swift!"
+
+"And I don't see that I can be of any service," added Ned, "so I'm off
+to my work."
+
+"All right," assented Tom. "I've got several new schemes to try. Some
+of them ought to work."
+
+Tom Swift was very busy for the next few days--so busy, in fact, that
+even Mary saw little of him. He was closeted with Mr. Baxter more than
+once, and that individual seemed to lose some of his bitter feelings
+over the loss of his formulae as he found he could be of service to the
+young inventor. For he was of service in suggesting new ways of
+combining fire-fighting chemicals, gained by his association with the
+fireworks concern.
+
+"And that's about all the benefit I derived from being with those
+scoundrels, Field and Melling," said Mr. Baxter gloomily.
+
+"You still think they took your dye formulae?" asked Tom.
+
+"I'm positive of it, but I can't prove anything. They threatened to get
+the best of me when I would not sell them, for a ridiculously low sum,
+an interest in the secrets. And I believe they did get the best of me
+during that fire."
+
+"I believe the same!" exclaimed Tom.
+
+"How is that? What do you know? Can you help me prove anything against
+them?" eagerly asked the chemist.
+
+"Well, I don't know," answered Tom slowly. "I'll tell you what I heard."
+
+Thereupon he related the conversation he had overheard while with Mary
+at the wayside inn. The eyes of Josephus Baxter gleamed as he listened
+to this recital.
+
+"So that was their game!" he cried, as he smote the table with his
+fist, thereby nearly upsetting a test tube of acid, which Tom caught
+just in time. "I knew something crooked was going on, and they thought
+I'd be so badly overcome in the fire that I wouldn't know, or wouldn't
+remember, what happened."
+
+"What did happen?" asked Tom. "All I know is that you were overcome in
+the laboratory room."
+
+"It's too long a story to tell in detail now," said Mr. Baxter. "But
+the main facts are that through misrepresentations I was induced to
+associate myself with Field and Melling. They had a good factory for
+the making of fireworks, and some of the chemicals used in that
+industry also enter into the manufacture of the kind of dyes I have in
+mind to make. So I associated myself with them, they agreeing to let me
+use their laboratory.
+
+"One night they came to see me as I was working there over my formulae.
+They pretended to have discovered something in an expired patent that
+nullified what I had. I did not believe this to be so, and I brought
+out my formulae to compare with theirs--or what they said they had. The
+next thing I remember was that the fire broke out and my formulae
+disappeared. Then I was overcome, and I did not care what happened to
+me, for, having lost the valuable dye formulae, I did not think life
+worth living.
+
+"Perhaps I was foolish," said Mr. Baxter, "but I had tried so many
+things and failed, and I counted so much on these formulae that it
+seemed as if the bottom dropped out of everything when I lost them."
+
+"I know," said Tom sympathetically. "I've been in the same boat myself.
+But are you sure they took the papers which meant so much to you?"
+
+"I don't see who else could," answered the chemist. "The papers were in
+a tin box on the table in the room where I was overcome by fire gases,
+or where, perhaps, they drugged me. I am not clear on this point. And
+afterward the tin box could not be found. There wasn't enough fire in
+that room to have melted it."
+
+"No," agreed Tom, "it was mostly smoke in there, and smoke won't melt
+tin. Nor did I see any box on the table when we carried you out."
+
+"Then the only other surmise is that Field and Melling got away with my
+formulae during the excitement and when I was half unconscious," Went
+on Mr. Baxter bitterly. "But you can see how foolish I would be to
+accuse them in court. I haven't a bit of proof."
+
+"Not much, for a fact," agreed Tom. "Well, with what I heard and what
+you tell me, perhaps we can work up a case against them later. I'll go
+over it with Ned. He has a better head for business than I."
+
+"Yes, we inventors need some business brains; or at least the time to
+give to business problems," agreed the chemist. "But enough of my
+troubles. Let's get at this chemical compound of yours."
+
+Tom and Mr. Baxter spent many days and nights perfecting the
+fire-extinguisher chemical, and, after repeated tests, Tom felt that he
+was nearer his goal.
+
+One afternoon Ned called, and Tom invited him to go for a ride in a
+small but speedy aeroplane.
+
+"Anything special on?" asked the young manager.
+
+"In a way, yes," Tom answered. "I'm having a firm in Newmarket make me
+some different containers, and they have promised me samples today. I
+thought I'd take a fly over and get them. I have the chemical compound
+all but perfected now, and I want to give it another test."
+
+"All right, I'm with you," assented Ned. "Newmarket," he added
+musingly. "Isn't that where Field and Melling are now?"
+
+"Yes. They have a factory on the outskirts of the place, and their
+offices are in the Landmark Building. But we aren't going to see them,
+though we may call on them later, when you have that case better worked
+up." For Ned's services had been enlisted to aid Mr. Baxter.
+
+"I shall need a little more time," remarked Ned. "But I think we can at
+least bluff them into playing into our hands. I have a report to hear
+from a private detective I have hired."
+
+"I hope we can do something to aid Baxter," remarked Tom. "He has done
+me good service in this chemical fire extinguisher matter."
+
+A little later Tom and Ned were speeding through the air on their way
+to Newmarket. The rapid flier was making good time at not a great
+height when Ned, leaning forward, appeared to be gazing at something in
+the near distance.
+
+"What's the matter?" asked Tom, for he had his silencer on this craft
+and it was possible for the occupants to converse. "Do you hear one of
+the cylinders missing, Ned?"
+
+"No. But what's that smoke down there?" and Ned pointed. "It looks like
+a fire!"
+
+"It is a fire!" exclaimed Tom, as he took an observation. "Not a big
+one, but a fire, just the same. If only--"
+
+He did not finish what he started to say, but changed the direction of
+his air craft and headed directly toward a pall of smoke about a mile
+away.
+
+In a few seconds they were near enough to make out the character of the
+blaze.
+
+"Look, Tom!" cried Ned. "It's an immense tree on fire!"
+
+"A tree!" exclaimed Tom, half incredulously, for he was leaning forward
+to look at one of the aeroplane gages and did not have a clear view of
+what Ned was looking at.
+
+"Yes, as sure as Mr. Damon would bless something if he were here! It's
+a tree on fire up near the top!"
+
+"That's strange!" murmured Tom. "But it may give me just the chance
+I've been looking for."
+
+Ned wondered at this remark on the part of his chum as the airship drew
+nearer the blazing monarch in the patch of woods over which they were
+then hovering.
+
+
+
+
+CHAPTER XII
+
+TOM IS LONESOME
+
+
+"This is certainly the strangest sight I ever saw," remarked Ned, as he
+and his chum flew nearer and nearer to the smoking and blazing tree.
+"Is the world turning upside down, Tom, when fires start in this
+fashion?"
+
+"I fancy it can easily be explained," answered the young inventor.
+"We'll go into that later. Here, Ned, grab hold of that tin can on the
+floor and take out the screw plug."
+
+"What's the idea?"
+
+"I want you to drop it as nearly as you can right into the midst of the
+tree that's on fire."
+
+"Oh, I get your drift! Well, you can count on me."
+
+Ned picked up from the floor of their aeroplane a metal can similar to
+those Tom used to hold oil or perhaps spare gasoline when he was
+experimenting on airship speed. The opening was closed with a screw
+plug, with wings to afford an easier grip. As Ned unscrewed this his
+nostrils were greeted by an odor that made him gasp.
+
+"Don't mind a little thing like that," cried Tom. "Drop it down, Ned!
+Drop it down! We're going to be right over the tree in another second
+or two!"
+
+Ned leaned over the side of the craft and had a good view of the
+strange sight. The tree that was on fire was a dead oak of great size,
+dwarfing the other trees in the grove in which it stood. In common with
+other oaks this one still retained many of its dried leaves, though it
+was devoid, or almost devoid, of life. Ned noticed in the branches many
+irregularly shaped objects, and it appeared to be these that were on
+fire, blazing fiercely.
+
+"It looks as though some one had tied bundles of sticks in the tree and
+set them on fire," Ned thought as he poised the opened tin of the
+evil-smelling compound on the edge of the aeroplane's cockpit.
+
+"Let her go, Ned!" cried Tom. "You'll be too late in another second!"
+
+Ned raised himself in his seat and threw, rather than let fall, the can
+straight for the blazing tree. Like a bomb it shot toward earth, and
+Ned and Tom, looking down, could see it strike a limb and break open,
+the rupture of the can letting loose the liquid contained in it.
+
+And then, before the eyes of Tom and Ned, the fire seemed to die out as
+a picture melts away on a moving picture screen. The smoke rolled away
+in a ball-like cloud, and the flames ceased to crackle and roar.
+
+"Well, for the love of molasses! what happened, Tom?" cried Ned, as the
+young inventor guided his craft about in a big circle to come back
+again over the tree. He wanted to make sure that the fire was out.
+
+It was!
+
+"What sent that blaze to the happy hunting grounds?" asked Ned.
+
+"My new aerial extinguisher," answered Tom, with justifiable pride in
+his voice. "This fire happened in the nick of time for me, Ned. I had a
+tin of my new combination in the car, not with any intention of using
+it, though. I intended to pour it in the new containers I am having
+made in Newmarket to see if it would corrode them, a thing I wish to
+avoid.
+
+"But when I saw that tree on fire I couldn't resist the temptation to
+use my very latest combination of chemicals. It is so recent that I
+haven't actually tried it on a blaze yet, though I had figured out in
+theory that it ought to work. And it did, Ned! It worked!"
+
+"Well, I should say so!" agreed his chum. "That blaze was doused for
+fair. The test could not have been better. But what in the name of a
+volunteer fire department set that tree to blazing, Tom?"
+
+"I'll tell you in a moment. I want to make some notes before I forget.
+That combination seems to be just of the right strength. It did the
+trick. Here, take the wheel and hold her steady while I jot down some
+memoranda before they get away from me."
+
+Ned was capable of managing an airship, especially under Tom's watchful
+eye, and as this craft was one with dual controls there was no
+difficulty in shifting from one steersman to the other.
+
+So while Ned guided, now and then gazing down at the tree from which
+some smoke still arose, though the fire was all out, Tom made the
+necessary scientific notes for future amplification.
+
+"And now," observed Ned, as his chum resumed the wheel, "suppose you
+enlighten me on how that tree came to be on fire--if you didn't set it
+yourself."
+
+"No, I didn't do that," Tom said, with a laugh. "And I only have a
+theory as to the cause of the blaze. But suppose we go down and take a
+look. There's a good field around this grove, and we can get a fine
+take off. I'll have to go back to Shopton anyhow, to get some more of
+the chemical."
+
+So the aeroplane made a landing, and then the mystery was explained.
+The dead oak, to which some of its last year's foliage still clung, was
+the abiding place of thousands of crows that had built their nests in
+it. There were hundreds of the big nests, made of dried sticks, mostly,
+and these made an ideal fuel for the fire.
+
+"But where are the crows, and what started the fire?" asked Ned.
+
+"I fancy the birds flew away as soon as they saw their homes on fire,"
+said Tom. "Or they may not have been at home. Flocks of crows often go
+to some distant feeding ground for the day, returning at night. I fancy
+that is what happened here.
+
+"As for the cause of the blaze, I believe it was set by some
+mischievous boys, who saw a good chance to have some fun without
+thought of doing any real damage. For the dead tree was of no value,
+and I imagine the farmers would be glad to see the flock of crows
+dispersed. Some boys probably climbed up and set fire to one of the
+nests, and then, when they saw the whole lot going, they became
+frightened and ran away."
+
+ And Tom's theory was, eventually, proved to be true. Some
+lads, wandering afield, had set fire to the crows' nests and then,
+frightened as they saw a bigger blaze than they intended, ran away.
+
+Tom and Ned did not remain to see what the returning crows might think
+about the destruction of their homes, provided they saw fit to return,
+but, starting the aeroplane, were again on their way.
+
+Tom had lingered long enough to make sure that his latest combination
+of chemicals had been just what was needed. He felt sure that by using
+a larger quantity, no fire, however fierce, could continue to blaze.
+
+"But I want to give it a good trial, Ned, as we did from the tower,"
+said Tom. "Though I don't believe there'll be a fizzle this time."
+
+It did not take long for Tom to secure another supply of the new
+chemical. He then went with it to the firm in Newmarket that was making
+his containers, or "bombs" as he called them.
+
+On his return he consulted with Mr. Baxter as to the ingredients of the
+fluid that had put out the blaze in the tree.
+
+"I believe you have at last hit on the right combination," said the
+chemist. "You are on the road to success, Tom. I wish I could say the
+same of myself."
+
+"Perhaps your formulae may come back to you as suddenly as they
+disappeared, or as quickly as I discovered that I had the right thing
+to put out the fire," said Tom hopefully.
+
+Busy days followed for the young inventor. Now that he was convinced he
+had at last evolved the right mixture of chemicals, he prepared to make
+a test on a larger scale than merely a blazing tree.
+
+"I'll try it with a fire in the pit," he said to his chum.
+
+Preparations were made, and the day before Tom was to carry out his
+plans he received a letter.
+
+"What's the matter? Bad news?" asked Ned, as he saw his friend's face
+change after reading the epistle.
+
+"Nothing much. Only Mary is going away, and I had expected her to be at
+the test," Tom answered.
+
+"Going away?" echoed Ned. "For long?"
+
+"Oh, no, only for a couple of weeks. She is going to visit an uncle and
+aunt in Newmarket, or just outside of that city. Another uncle, Barton
+Keith, has offices in the Landmark Building, I believe."
+
+"Landmark Building," murmured Ned. "Isn't that where Field and Melling
+hang out?"
+
+"Yes. But don't mention Mary's uncle in connection with them," laughed
+Tom. "He wouldn't like it."
+
+"I should say not!"
+
+Ned well remembered Mary's uncle, who had been associated with Tom in
+recovering the treasure in the undersea search.
+
+"Well, if she can't be here, she can't," said Tom, as philosophically
+as possible. "I'd better run over and bid her goodbye."
+
+This Tom did, though Ned noticed that his chum acted as though lonesome
+on his return.
+
+"But when he gets to work testing his new chemical he'll be all right,"
+decided Ned.
+
+
+
+
+CHAPTER XIII
+
+A SUCCESSFUL TEST
+
+
+"It took you long enough," Ned remarked as Tom entered the main office
+of the plant, having been to see Mary off on her trip to Newmarket.
+This was following his call of the night before to learn more
+particulars of her unexpected visit.
+
+"Yes, I didn't plan to be gone so long," apologized Tom. "But I thought
+while I was there I might as well go all the way with her."
+
+"And did you?"
+
+"Yes. In the electric runabout. I wanted to come back and get the
+airship, but she said she wanted to look nice when she met her
+relatives, and as yet airship travel is a bit mussy. Though when I get
+my cabined cruiser of the clouds I'll guarantee not to ruffle a curl of
+the daintiest girl!"
+
+"Getting poetical in your old age!" laughed Ned. "Well, here is that
+statement you said you wanted me to get ready. Want to go over it now?"
+
+"No, I guess not, as long as you know it's all right. I'm going to
+start right in and get ready for a bang-up test."
+
+"Of what--your new aerial fire fighting apparatus?"
+
+"Yes. Mr. Baxter and I are going to make up a lot of the chemical
+compound that--we discovered through using it on the blazing tree--will
+best do the trick. Then I'm going to try it on a pit fire, and after
+that on a big blaze with an airship."
+
+"Let me know when you do," begged Ned. "I want to see you do it."
+
+"I'll send you word," promised the young inventor.
+
+Then he began several days and nights of hard work. And he was glad to
+have the chance to occupy himself, for, though Tom professed not to be
+much affected by the departure of Mary Nestor, he really was very
+lonesome.
+
+"How is her uncle, Barton Keith, by the way?" asked Ned, when he called
+on his chum one day, to find him reading a letter which needed but half
+an eye to tell was from Mary.
+
+"About as usual," was the answer. "He sends word by Mary that he'll be
+glad to see us any time we want to call. He has some nice offices in
+the Landmark Building."
+
+"Those papers proving his right to the oil land, which you recovered
+from the sunken ship for him, must have made his fortune."
+
+"Well, yes--that and other things," agreed Tom. "Say, we had some
+exciting times on that undersea search, didn't we?"
+
+"Did you call on Mr. Keith when you went to Newmarket with Mary?" Ned
+wanted to know, for he and Tom had taken quite a liking to Miss
+Nestor's uncle.
+
+"No, I didn't get a chance. Besides, I wanted to keep away from the
+Landmark Building."
+
+"Why?"
+
+"Oh, I might run into Field and Melling, and I don't want to see them
+until I can accuse them, and prove it, of having taken Mr. Baxter's dye
+formulae."
+
+"Oh, yes, they're in the same building with Mr. Keith, aren't they? Why
+do they call it the Landmark? Though I suppose the answer is obvious."
+
+"Yes," assented Tom. "It's a big building--the tallest ever erected in
+that city, and a fine structure. Though while they were about it I
+don't see why they didn't make it fireproof."
+
+"Didn't they?" asked Ned, in surprise. "Then the insurance rates must
+be unusually high, for the companies are beginning to realize how fire
+departments, even in big cities, are hampered in fighting blazes above
+the tenth or twelfth stories."
+
+"Yes, it was a mistake not to have the Landmark Building fireproof,"
+admitted Tom. "And Mr. Keith says the owners are beginning to realize
+that now. It is what is called the 'slow burning' construction."
+
+"Insurance companies don't go much on that," declared Ned, who was in a
+position to know. "Well, let us hope it never catches fire."
+
+These were busy days for the young inventor. He laid aside all his
+other activities in order to perfect the plans for manufacturing his
+new chemical fire extinguisher on a large scale. For Tom realized that
+while a small quantity of chemicals in a compound might act in a
+certain way on one occasion, if the bulk should happen to be increased
+the experimenter could not always count on invariably the same results.
+
+There appeared to be at times a change engendered when a large quantity
+of chemicals were mixed which was not manifest in a small and
+experimental batch.
+
+So Tom wanted to mix up a big tank of his new chemical compound and see
+if it would work in large quantities as well as it did with the small
+amount Ned had dropped on the blazing tree.
+
+To this end Tom worked at night, as well as by day, and finally he
+announced to Ned and Mr. Damon, who called one evening, that he
+believed he had everything in readiness for an exhaustive test the next
+day.
+
+"There's the stuff!" exclaimed Tom, not a little proudly, as he waved
+his hand toward an immense carboy in the main shop. "That's what I hope
+will do the trick. Just take a--"
+
+"Hold on! Stop! That's enough! Bless my hair brush!" cried Mr. Damon,
+holding up a protesting hand. "If you take that cork out, Tom Swift,
+you and I will cease to be friends!"
+
+"I wasn't going to open it," laughed the young inventor. "It has a
+worse odor and seems to choke you more in a big quantity than when
+there's only a little. I was just going to shake the carboy to let you
+realize how full it was."
+
+"We'll take your word for it!" laughed Ned. "Now about your test. How
+are you going to work it?"
+
+"There are to be two tests," answered Tom. "The first, and the smaller,
+will be in the pit, as before, only this time we shall have what, I
+believe, will be the successful combination of chemicals to drop on it.
+
+"The second test will be the main one. In that I plan to have an old
+barn which I have bought set ablaze. Then Ned and I will sail over it
+in the airship and drop chemicals on it. The barn will be filled with
+empty boxes and barrels, to make as hot a fire as possible. You are
+invited to accompany us, Mr. Damon."
+
+"Will there be any smell?" asked the eccentric man, who seemed to have
+a dislike for anything that was not as agreeable as perfume.
+
+"No, the chemicals will be sealed in containers, which will be dropped
+from my airship as bombs were dropped in the war," said Tom.
+
+"On those conditions I'll go along," agreed Mr. Damon. "But bless my
+wedding certificate, Tom! don't tell my wife. She thinks I'm crazy
+enough now, associating with you and flying occasionally. If she
+thought I would help you battle with flames from the air she'd likely
+never speak to me again."
+
+"I'll not tell," promised Tom, laughing.
+
+Preparations for the test went on rapidly. In the morning a fire was to
+be started in the same pit where the experiment had partly failed
+before.
+
+From the platform over the blazing hole some of the new combination of
+chemicals was to be dropped. If it acted with success, as Tom believed
+it would, he proposed to go on with the more important test in the
+afternoon.
+
+To this end he had purchased from a farmer the right to set on fire an
+old ramshackle barn, standing in the midst of a field about three miles
+outside of Shopton. The barn was on an untilled farm, the house having
+been destroyed some years before, and it was not near any other
+structures, so that, even in a high wind, no damage would result.
+
+Tom had filled the barn with inflammable material, and was going to
+spare no effort to have the test as exhaustive as possible.
+
+The time came for the preliminary trial, and there were a few anxious
+moments after the oil-soaked boards and boxes in the pit were set
+ablaze.
+
+"Let her go!" cried Tom to his man on the elevated platform, and down
+fell the container of chemicals. It had no sooner struck and burst,
+letting loose a mass of flame-choking vapor, than the fire died out.
+
+"You've struck it, Tom! You've struck it!" cried Ned.
+
+"It begins to look so," agreed the young inventor. "But I'll not call
+myself out of the woods until this afternoon. Though we can consider it
+a success so far."
+
+Quite a throng was on hand when the old barn was set ablaze. Tom and
+Ned and Mr. Damon were there with the airship which had been especially
+fitted to carry the bombs filled with the extinguisher.
+
+In order to insure a quick, hot blaze the barn was fired on all four
+sides at once by Tom's men. When it was seen to be a veritable raging
+furnace of fire, Tom and his two friends took their places in the
+airship and rapidly mounted upward.
+
+Necessarily they had to circle off away from the blaze to get to the
+necessary height, but Tom soon brought the airship around again and
+headed for the black pall of smoke which marked the place of the
+blazing barn.
+
+"We'll all three send down bombs at the same time," Tom told his
+friends, as they darted forward. "When I give the word press the
+levers, and the chemical containers will drop. Then we'll hope for the
+best."
+
+Higher mounted the flames, and more fiercely raged the fire. The heat
+of it penetrated even aloft, where Tom and his friends were scudding
+along in the airship.
+
+"Now!" cried Tom, as his craft hovered for an instant in a favorable
+position for dropping the bombs. The young inventor, Mr. Damon, and Ned
+Newton pressed the levers. Looking over the sides of the craft, they
+saw three dark objects dropping into the midst of the burning barn.
+
+
+
+
+CHAPTER XIV
+
+OUT OF THE CLOUDS
+
+
+Almost as though some giant hand had dropped an immense cloak over the
+fire in the barn, so did the blaze die down instantly after Tom Swift's
+extinguishing liquid had been dropped into the seething caldron of
+flame. For a moment there was even no smoke, but as the embers remained
+hot and glowing for a time, though the flames themselves were quenched,
+a rolling vapor cloud began to ascend shortly after the first cessation
+of the fire. But this only lasted a little while.
+
+"You've turned the trick, Tom!" cried Ned, leaning far over to look at
+what was left of the barn and its contents.
+
+"Bless my insurance policy, I should say so!" exclaimed Mr. Damon. "It
+was certainly neat work, Tom!"
+
+"It does look as if I'd struck the right combination," admitted Tom,
+and he felt justifiable pride in his achievement.
+
+"Look so! Why, hang it all, man, it is so!" declared Ned. "That fire
+went out as if sent for by a special delivery telegram to give a
+hurry-up performance in another locality. Look, there's hardly any
+smoke even!"
+
+This was so, as the three occupants of the rapidly moving airship could
+see when Tom circled back to pass again over the almost destroyed
+structure. He had waited until it was almost consumed before dropping
+his chemicals, as he wished to make the test hard and conclusive. Now
+the fire was out except for a few small spots spouting up here and
+there, away from the center of the blaze.
+
+"Yes, I guess she doesn't need a second dose," observed Tom, when he
+saw how effective had been his treatment of the fire. "I had an
+additional batch of chemicals on hand, in case they were needed," he
+added, and he tapped some unused bombs at his feet.
+
+"I call this a pretty satisfactory test," declared Ned. "If you want to
+form a stock company, Tom, and put your aerial fire-fighting apparatus
+on the market, I'll guarantee to underwrite the securities."
+
+"Hardly that yet," said Tom, with a laugh. "Now that I have my chemical
+combination perfected, or practically so, I've got to rig up an airship
+that will be especially adapted for fighting fires in sky-scrapers."
+
+"What more do you want than this?" asked Ned, as his chum prepared to
+descend in the speedy machine.
+
+"I want a little better bomb-releasing device, for one thing. This
+worked all right. But I want one that is more nearly automatic. Then I
+am going to put on a searchlight, so I can see where I am heading at
+night."
+
+"Not your great big one!" cried Ned, recalling the immense electric
+lantern that had so aided in capturing the Canadian smugglers.
+
+"No. But one patterned after that." Tom answered.
+
+"Bless my candlestick!" exclaimed Mr. Damon, "what do you want with a
+searchlight at a fire, Tom? Isn't there light enough at a blaze,
+anyhow?"
+
+"No," answered the young inventor, as he made his usual skillful
+landing. "You know all the big city fire departments have searchlights
+now for night work and where there is thick smoke. It may be that some
+day, in fighting a sky-scraper blaze from the clouds at night, I'll
+have need of more illumination than comes from the flames themselves."
+
+"Well, you ought to know. You've made a study of it," said Mr. Damon,
+as he and Ned alighted with Tom, the latter receiving congratulations
+from a number of his friends, including members of the Shopton fire
+department who were present to witness the test.
+
+"Mighty clever piece of work, Tom Swift!" declared a deputy chief. "Of
+course we won't have much use for any such apparatus here in Shopton,
+as we haven't any big buildings. But in New York, Chicago, Pittsburgh
+and other cities--why, it will be just what they need, to my way of
+thinking."
+
+"And he needn't go so far from home," said Mr. Damon. "There is one
+tall building over in Newmarket--the Landmark. I happen to own a little
+stock in the corporation that put that up, along with other buildings,
+and I'm going to have them adopt Tom Swift's aerial fire-fighting
+apparatus."
+
+"Thank you. But you don't need to go to that trouble," asserted Tom.
+"My idea isn't to have every sky-scraper equipped with an airship
+extinguisher."
+
+"No? What then?" asked Mr. Damon.
+
+"Well, I think there ought to be one, or perhaps two, in a big city
+like New York," Tom answered. "Perhaps one outfit would be enough, for
+it isn't likely that there would be two big fires in the tall building
+section at the same time, and an airship could easily cover the
+distance between two widely separated blazes. But if I can perfect
+this machine so it will be available for fires out of the reach of
+apparatus on the ground, I'll be satisfied."
+
+"You'll do it, Tom, don't worry about that!" declared the deputy chief.
+"I never saw a slicker piece of work than this!"
+
+And that was the verdict of all who had witnessed the performance.
+
+With the successful completion of this exacting test and the
+knowledge that he had perfected the major part of his aerial
+fire-extinguisher--the chemical combination--Tom Swift was now able to
+devote his attention to the "frills" as Ned called them. That is, he
+could work out a scheme for attaching a searchlight to his airship and
+make better arrangements for a one-man control in releasing the
+chemical containers into the heart of a big blaze.
+
+Tom Swift owned several airships, and he finally selected one of not
+too great size, but very powerful, that would hold three and, if
+necessary, four persons. This was rebuilt to enable a considerable
+quantity of the fire-extinguishing liquid to be stored in the under
+part of the somewhat limited cockpit.
+
+This much done, and while his men were making up a quantity of the
+extinguisher, using the secret formula, and storing it in suitable
+containers, Tom began attaching a searchlight to his "cloud
+fire-engine," as Koku called it.
+
+The giant was aching to be with Tom and help in the new work, but Koku
+was faithful to the blinded Eradicate, and remained almost constantly
+with the old colored man.
+
+It was touching to see the two together, the giant trying, in his kind,
+but imperfect way, to anticipate the wishes of the other, with whom he
+had so often disputed and quarreled in days past. Now all that was
+forgotten, and Koku gave up being with Tom to wait on Eradicate.
+
+While the colored man was, in fact, unable to see, following the
+accident when Tom was experimenting with the fire extinguisher, it was
+hoped that sight might be restored to one eye after an operation. This
+operation had to be postponed until the eyes and wounds in the face
+were sufficiently healed.
+
+Meanwhile Rad suffered as patiently as possible, and Koku shared his
+loneliness in the sick room. Tom came to see Rad as often as he could,
+and did everything possible to make his aged servant's lot happier. But
+Rad wanted to be up and about, and it was pathetic to hear him ask
+about the little tasks he had been wont to perform in the past.
+
+Rad was delighted to hear of Tom's success with the new apparatus,
+after having been told how quickly the barn fire was put out.
+
+"Yo'--yo' jest wait twell I gits up, Massa Tom," said Rad. "Den Ah'll
+help make all de contraptions on de airship."
+
+"All right, Rad, there'll be plenty for you to do when the time comes,"
+said the inventor. And he could not help a feeling of sadness as he
+left the colored man's room.
+
+"I wonder if he is doomed to be blind the rest of his life," thought
+Tom. "I hope not, for if he does it will be my fault for letting him
+try to mix those chemicals."
+
+But, hoping for the best, Tom plunged into the work ahead of him. He
+did not want to offer his aerial fire extinguisher to any large city
+until he had perfected it, and he was now laboring to that end.
+
+One day, in midsummer, after weary days of toil, Tom took Ned out for a
+ride in the machine which had been fitted up to carry a large supply of
+the chemical mixture, a small but powerful searchlight, and other new
+"wrinkles" as Tom called them, not going into details.
+
+"Any special object in view?" asked Ned, as Tom headed across country.
+"Are you going to put out any more tree fires?"
+
+"No, I haven't that in mind," was the answer. "Though of course if we
+come across a blaze, except a brush fire, I may put it out. I have the
+bombs here," and Tom indicated the releasing lever.
+
+"What I want to try now is the stability of this with all I have on
+board," he resumed. "If she is able to travel along, and behave as well
+as she did before I made the changes, I'll know she is going to be all
+right. I don't expect to put out any fires this trip."
+
+In testing the ship of the air Tom sent her up to a good height,
+heading out over the open country and toward a lake on the shores of
+which were a number of summer resorts. It was now the middle of the
+season, and many campers, cottagers and hotel folk were scattered about
+the wooded shore of the pretty and attractive body of water.
+
+Tom and Ned had a glimpse of the lake, dotted with many motor boats and
+other craft, as the airship ascended until it was above the clouds.
+Then, for a time, nothing could be seen by the occupants but masses of
+feathery vapor.
+
+"She's working all right," decided Tom, when he found that he could
+perform his usual aerial feats with his craft, laden as she was with
+apparatus, as well as he had been able to do before she was so
+burdened. "Guess we might as well go down, Ned. There isn't much more
+to do, as far as I can see."
+
+Down out of the heights they swept at a rapid pace. A few moments later
+they had burst through the film of clouds and once more the lake was
+below them in clear view.
+
+Suddenly Ned pointed to something on the water and cried:
+
+"Look, Tom! Look! A motor boat in some kind of trouble! She's sinking!"
+
+
+
+
+CHAPTER XV
+
+COALS OF FIRE
+
+
+Tom Swift saw the craft almost as soon as did his chum. It was rather a
+large-sized motor boat, quite some distance out from shore, and there
+was no other craft near it at this time. From the quick, first view Tom
+and Ned had of it, they decided that a party of excursionists were on a
+pleasure trip.
+
+But that an accident had happened, and that trouble, if not, indeed,
+danger, was imminent, was at once apparent to the young inventor and
+the other occupant of the swiftly moving airship.
+
+For as Tom shut off his motor, to volplane down, thus reducing all
+noise on his craft, they could dimly hear the shouts and calls for
+help, coming from the water craft below them.
+
+"Help! Help!" came the impassioned appeals, floating up to Tom and Ned.
+
+"We're coming!" Tom answered, though it is doubtful if his voice was
+heard. Sound does not seem to carry downward as well as upward, and
+though Tom's craft was making scarcely any noise, save that caused by
+the rush of wind through the struts and wires, there was so much
+confusion on the motor boat, to say nothing of the engine which was
+going, that Tom's encouraging call must have been unheard.
+
+"What are you going to do, Tom?" asked Ned, "You can't land on the
+water!"
+
+"I know it; worse luck! If I only had the hydroplane, now, we could
+make a thrilling rescue--land right beside the other boat and take 'em
+all off. But, as it is, I'll have to land as near as I can and then we
+will look for a boat to go out to them in."
+
+Ned saw, now, what Tom's object was. On one shore of the lake was a
+large, level field, suitable for a landing place for the craft of the
+air. At least it looked to be a suitable place, but Tom would be
+obliged to take a chance on that. This field sloped down to the beach
+of the lake, and as Ned and his chum came nearer to earth they could
+see several boats on shore, though no persons were near them. Had there
+been, probably they would have gone to the rescue.
+
+Tom cast a rapid look across the sheet of water, to make sure his
+services were really needed. The motor boat was lower in the lake now,
+and was, undoubtedly, sinking. And no other craft was near enough to
+render help. Though distant whistles, seeming to come from approaching
+craft, told of help on the way.
+
+"Hold fast, Ned!" cried Tom, as they neared the earth. "We may bump!"
+
+But Tom Swift was too skillful a pilot to cause his craft to sustain
+much of a crash. He made an almost perfect "three point landing," and
+there would have been no unusual shaking, except for the fact that the
+field was a bit bumpy, and the craft more heavily laden than usual.
+
+"Good work, Tom!" cried Ned, as the Lucifer slackened her speed, the
+young inventor having sent her around in a half circle so that she now
+faced the lake. Then Tom and Ned climbed from the cockpit, throwing off
+goggles and helmets as they ran to the shore where there were several
+rowboats moored.
+
+"And a little old-fashioned naphtha launch! By all that's lucky!" cried
+Tom. "I didn't think they made these any more. If she only works now!"
+
+There was a little dock at this point on the lake, and the boats
+appeared to be held at it for hire. But no one was in charge, and Tom
+and Ned made free with what they found. They considered they had this
+right in the emergency.
+
+The naphtha launch was chained and padlocked to the dock, but using an
+oar Tom burst the chain.
+
+"Get one of the rowboats and fasten it to the back of the launch!" Tom
+directed Ned. "I don't believe this craft will hold them all," and he
+nodded toward those aboard the sinking boat--for it was only too
+plainly sinking now.
+
+"All right!" voiced Ned. "I'm with you. Can you get that engine to
+work?"
+
+"She's humming now," announced Tom, as he turned on the naphtha, and
+threw in a blazing match to ignite it, this act saving his hand.
+Naphtha engines are a trifle treacherous.
+
+A few moments later, though not as quickly as a gasoline craft could
+have been gotten under way, Tom was steering the small launch out and
+away from the dock, and toward the craft whence came the faint calls
+for help. Behind them Tom and Ned towed a large rowboat.
+
+Tom speeded the naphtha craft to its limit, and, fortunately for those
+in danger, it was a fast boat. In less time than they had thought
+possible, the young inventor and his chum were near the boat that was
+now low in the water--so low, in fact, that her rail was all but awash.
+
+"Oh, take us out! Save us!" screamed some of the girls.
+
+"Take it easy now," advised Tom, approaching with care. "We've got room
+for you all. Ned, get back in the rowboat and bring that alongside--on
+the other side. We'll take you all in," he added.
+
+"Girls first!" called Ned sternly, as he saw one young fellow about to
+scramble into the naphtha boat.
+
+"Sure, girls first!" agreed the skipper of the disabled craft. "Hit a
+submerged log," he explained to Tom, as the work of rescue proceeded.
+"Stove a hole in the bow, but we stuffed coats and things in, and made
+it a slow leak. Kept the engine going as long as we could, but I
+thought no one would ever come! Lucky you happened to see us from up
+there!"
+
+"Yes," assented Tom shortly. He and Ned were too busy to talk much, as
+they were aiding in getting some hysterical girls and young women into
+the two sound craft. And when the last of the picnic party had been
+taken off, the boat with a hole in it gave a sudden lurch, there was a
+gurgling, bubbling sound, and she sank quickly.
+
+Tom and Ned had anticipated this, however, and had their craft well out
+of the way of the suction.
+
+"You'll all have to sit quiet," Tom warned his passengers as he took
+Ned's boat, with her load, in tow. "I've got about all the law allows
+me to carry," he added grimly.
+
+"Oh, what ever would we have done without you?" half sobbed one girl.
+
+"I guess you could have managed to swim ashore," Tom answered, not
+wanting to make too much of his effort.
+
+Then more rescue boats came up, but those in the naphtha craft, and
+Ned's smaller one, refused to be transferred, and remained with our
+friends until safely landed at the dock.
+
+Receiving the half-hysterical thanks of the party, and leaving them to
+explain matters to the owner of the borrowed boats, Ned and Tom went
+back to the Lucifer, and were soon aloft again.
+
+"Pretty slick act, Tom," remarked Ned.
+
+"Oh, it's all in the day's work," was the answer. He had all but
+perfected his big fire-extinguishing aeroplane, and was contemplating
+means by which he could give a demonstration to the fire department of
+some big city, when Mr. Baxter asked to see Tom one day. There was a
+look on the face of the chemist that caused Tom to exclaim with a good
+deal of concern:
+
+"What's the matter?"
+
+"Only the same old trouble," was the discouraged answer. "I can't get
+on the track of my lost secret formulae. If I had Field and Melling
+here now I--I'd--"
+
+He did not finish his threat, but the look on his face was enough to
+show his righteous anger.
+
+"I wish we could do something to those fellows!" exclaimed Tom
+energetically. "If we only had some direct evidence against them!"
+
+"I've got evidence enough--in my own mind!" declared Mr. Baxter.
+
+"Unfortunately that doesn't do in law," returned Tom. "But now that I
+have this airship firefighter craft so nearly finished, I can devote
+more time to your troubles, Mr. Baxter."
+
+"Oh, I don't want you bothered over my troubles," said the chemist.
+"You have enough of your own. But I'm at my wit's end what to do next."
+
+"If it is money matters," began Tom.
+
+"It's partly that, yes," said the other, in a low voice. "If I had
+those dye formulae, I'd be a rich man."
+
+"Well, let me help you temporarily," begged Tom. And the upshot of the
+talk was that he engaged Mr. Baxter to do certain research work in the
+Swift laboratories until such time as the chemist could perfect certain
+other inventions on which he was working.
+
+In return for his kindness to a fellow laborer, Tom received from Mr.
+Baxter some valuable hints about fire-extinguishing chemicals, one
+hint, alone, serving to bring about a curious situation.
+
+It was several days after the accident to the motor boat from which the
+young inventor and Ned Newton had rescued the party of pleasure seekers
+that Tom was visited by Mr. Damon, who drove over in his car.
+
+"Have you anything special to do, Tom?" asked the eccentric man. "If
+you haven't I wish you'd take a ride with me. Not for mere pleasure!
+Bless my excursion ticket, don't think that, Tom!" cried his friend
+quickly.
+
+"I know better than to ask you out for a pleasure jaunt. But I have
+become interested in a certain candy-making machine that a man over in
+Newmarket is anxious to sell me a share in, and I'd like to get your
+opinion. Can you run over?"
+
+"Yes," Tom answered. "As it happens I am going to Newmarket myself."
+
+"Oh, I forgot about Mary Nestor being there!" laughed Mr. Damon. "Sly
+dog, Tom! Sly dog!" and he nudged the youth in the ribs.
+
+"It isn't altogether Mary. Though I am going to see her," Tom admitted.
+"It has to do with a little apparatus I am getting up. I can capture
+several birds in the same auto, so I'll go along."
+
+This pleased Mr. Damon, and he and Tom were soon speeding over the
+road. It was just outside Newmarket that they saw an automobile stalled
+at the foot of a hill which they topped. It needed but a glance to show
+that there was serious trouble. As Mr. Damon's car went down the slope
+two men could be seen leaping from the other machine. And, as they did
+so, flames burst out of the rear of the stalled machine.
+
+"Fire! Fire!" cried Mr. Damon, rather needlessly it would seem, as any
+one could see the blaze.
+
+"Another chance!" exclaimed Tom, reaching down between his feet for a
+wrapped object he had placed in Mr. Damon's car. "It's Field and
+Melling!" he cried. "The two men who boasted of having put it over on
+Mr. Baxter. Their car is blazing. Here's where I get a chance to heap
+coals of fire on their heads!"
+
+
+
+
+CHAPTER XVI
+
+VIOLENT THREATS
+
+
+Tom Swift's companion in the automobile was sufficiently acquainted
+with this old expression to understand readily what it meant. And as he
+directed his car as close as was safe to the blazing car, Mr. Damon
+asked:
+
+"Are you going to put out that fire for them, Tom?"
+
+"I'm going to try," was the grim answer.
+
+The young inventor was rapidly taking out of wrapping paper a metal
+cylinder with a short nozzle on one end and a handle on the other. It
+was, obviously, a hand fire extinguisher of a type familiar to all.
+
+"Wait Tom, I'll slow up a little more," said Mr. Damon, as he applied
+the brakes with more force. "Bless my court plaster! don't jump and
+injure yourself."
+
+But Tom Swift was sufficiently agile to leap from the automobile when
+it was still making good speed. He did not want Mr. Damon to approach
+too close to the burning car, for there might be an explosion. At the
+same time, he rather discounted the risk to himself, for he ran right
+in, while the two men, who had leaped from the blazing machine, hurried
+to a safe distance.
+
+Tom held in readiness a small hand extinguisher. It was one he had
+constructed from an old one found in the shop, but it contained some of
+his own chemicals, the original solution having been used at some time
+or other. It was the intention of the young inventor to put on the
+market a house-size extinguisher after he had disposed of his big
+airship invention.
+
+"Look out there! The gasoline tank may go up!" cried Field, the small
+man with the big voice.
+
+Tom did not answer, but ran in as close as was necessary and began to
+play a small stream from his hand extinguisher on the blazing car. He
+was thus able to direct the white, frothy chemical better than when he
+had shot it from the airship, and in a few seconds only some wisps of
+curling smoke remained to tell of the presence of the fire. The
+automobile was badly charred, but the damage was not past redemption.
+
+"Bless my check book! you did the trick, Tom," cried Mr. Damon, as he
+alighted and came up to congratulate his companion.
+
+"Yes. But this wasn't much," Tom said. "I didn't use half the charge.
+Short circuit?" he asked Field and Melling who were now returning,
+having seen that the danger was passed.
+
+"I--I guess so," replied Melling, in his squeaky voice. "We--we are
+much obliged to you."
+
+"No thanks necessary," said Tom, a bit shortly, as he turned to go back
+with Mr. Damon to their car. "It's what any one would do under like
+circumstances."
+
+"Only you did it very effectively," observed Field.
+
+Tom was wondering if they knew who he was and of his association with
+Josephus Baxter. He did not believe the men recognized him as the
+person who had been at the Meadow Inn one day with Mary. They had
+hardly glanced at him then, he thought.
+
+"That's a mighty powerful extinguisher you have there, young man," said
+Melling. "May I ask the make of it? We ought to carry one like it on
+our car," he told his companion.
+
+"It is the Swift Aerial Fire Extinguisher," said Tom gravely, with a
+glance at Mr. Damon.
+
+"The Swift--Tom Swift?" exclaimed Melling. "Do you mean--"
+
+"I am Tom Swift," put in the young inventor quickly. "And this is one
+of my inventions. I might add," he said slowly, looking first Melling
+and then Field full in the face, "that I was aided in perfecting the
+chemical extinguisher by Josephus Baxter."
+
+The effect on the two men, whom Tom believed were scoundrels, was
+marked.
+
+"Baxter!" cried Field.
+
+"Is he associated with you?" demanded Melling.
+
+"Not officially," Tom answered, delighted at the chance to "rub it in,"
+as he expressed it later. "I have been helping him, and he has been
+helping me since he lost his dye formulae in--in your fire!"
+
+"Does he say he lost them in the fire of our factory?" demanded Field
+aggressively.
+
+"He believes he did," asserted Tom. "I helped carry him out of the
+laboratory of your place when he was almost dead from suffocation. He
+remembers that he had the formulae then, but since has been unable to
+find them."
+
+"He'd better be careful how he accuses us!" blustered Field, in his big
+voice.
+
+"We could have the law on him for that!" squeaked the bigger Melling.
+
+"He hasn't accused you," said Tom easily. "He only says the formulae
+disappeared during the fire in your place, and he is just wondering,
+that is all--just wondering!"
+
+"Well, he--we, I--that is, we haven't anything from Baxter that we
+didn't pay for," declared Field. "And if he goes about saying such
+things he'd better be careful. I am going--"
+
+But he suddenly became silent as his companion's elbow nudged him. And
+then Melling took up the talk, saying:
+
+"We're much obliged to you, Mr. Swift, for putting out the fire in our
+car. But for you it would have been destroyed. And if you ever want to
+sell the extinguisher process of yours, you'll find us in the market.
+We are going into the dye business on a large scale, and we can always
+use new chemical combinations."
+
+"My extinguisher is not for sale," said Tom dryly. "Come on, Mr. Damon.
+We can take you into town, I suppose," Tom went on, looking at his
+eccentric friend for confirmation, and finding it in a nod. "But I
+doubt if we could tow you, as we are in a hurry, and--"
+
+"Oh, thank you, we'll look over our machine before we leave it," said
+Melling. "It may be that we can get it to go."
+
+Tom doubted this, after a look at the charred section, but he easily
+understood the dislike of the men, upon whose heads he had heaped coals
+of fire, to ride with him and Mr. Damon.
+
+So Field and Melling were left standing in the road near their stranded
+car, which, but for Tom Swift's prompt action, would have been only a
+heap of ruins.
+
+Tom first visited the man who had a candy machine, in which the owner
+wanted to interest Mr. Damon. After seeing a demonstration and giving
+his opinion, he attended to his own affairs, in which his hand
+extinguisher played a part. Then he called on Mary Nestor at her
+relative's home.
+
+"Oh, but it's good to see you again, Tom!" cried Mary, after the first
+greeting. "What have you been doing, and what's all that white stuff on
+your coat?"
+
+"Fire extinguisher chemical," Tom answered, and he related what had
+happened.
+
+"What's the matter with your aunt, Mary? She seems worried about
+something," he said, after the aunt with whom Mary was staying had come
+in, greeted Tom briefly, and gone out again.
+
+"Oh, she and Uncle Jasper are worried over money matters, I believe,"
+Mary said. "Uncle Jasper invested heavily in the Landmark Building
+here, and now, I understand, it is discovered that it was put up in
+violation of the building laws--something about not being fire-proof.
+Uncle Jasper is likely to lose considerable money.
+
+"It isn't that it will make him so very poor," Mary went on. "But
+Uncle Barton Keith--you remember you went on the undersea search with
+him--Uncle Barton warned Uncle Jasper not to go into the Landmark
+Building scheme."
+
+"And Uncle Jasper did, I take it," said Tom.
+
+"Yes. And now he's sorry, for not only may he lose money, but Uncle
+Barton will laugh at him, and Uncle Jasper hates that worse than losing
+a lot. But tell me about yourself, Tom. What have you been doing? And
+is Eradicate going to get better?"
+
+"I hope so," Tom said. "As for me--"
+
+But he was interrupted by loud voices in the hall. He recognized the
+tones of Mary's Uncle Jasper saying:
+
+"They're scoundrels, that's what they are! Just plain scoundrels! When
+I accuse them of swindling me and others in that Landmark Building deal
+they have the nerve to ask me to invest money in some secret dye
+formulae they claim will revolutionize the industry! Bah! They're
+scoundrels, that's what they are--Field and Melling are scoundrels, and
+I'm going to have them arrested!"
+
+
+
+
+CHAPTER XVII
+
+A TOWN BLAZE
+
+
+Mary's uncle, Jasper Blake, always an impetuous man, opened the door so
+quickly that Tom, who was standing near it talking to Mary, barely had
+time to move aside.
+
+"Oh, Tom, excuse me! Didn't see you!" bruskly went on Mr. Blake. "But
+this thing has gotten on my nerves and I guess I'm a bit wrought up.
+
+"There isn't any guessing about it, Uncle Jasper," said Mary, with a
+laugh and a look at Tom to warn him not to tell her relative that he
+had just befriended Field and Melling. "For," as Mary said to Tom
+later, "he would positively rave at you."
+
+Tom was wise enough to realize this, and so, after some laughing
+reference to the effect that he would have to wear protective armor if
+he stood near doors when Mary's uncle opened them so suddenly, the
+conversation became general.
+
+"I hope you never get roped in as I have been," said Mr. Blake, as he
+sat down. "Those scoundrels, Field and Melling, would rob a baby of his
+first tooth if they had the chance!"
+
+"No, I am not likely to have anything to do with them; though I have
+met them," and Tom gave Mary a glance. "But did I hear you say they are
+embarking on a dye enterprise?" he asked. "I couldn't help overhearing
+what you said in the hall," he explained.
+
+"That's the story they tell," said Uncle Jasper. "I was foolish enough
+to invest in the Landmark Building, and now I'm likely to lose it all
+in a lawsuit."
+
+"I mentioned it," said Mary.
+
+"And that isn't the worst," went on Mr. Blake. "But Barton--that's your
+friend of the submarine--will give me the laugh, for he was asked to
+invest in the same building, and didn't."
+
+"Oh, maybe it will all turn out right," said Tom consolingly. "My
+friend Mr. Damon has a little stock in the same structure."
+
+"Nothing those two scoundrels have anything to do with will turn out
+right," declared Mary's uncle. "And to think of their nerve when they
+ask me to go in with them on a dye scheme!"
+
+"That's what interests me," said Tom.
+
+"Well, take my advice and don't become interested to the extent of
+investing any money," warned Mr. Blake. "I'm not going to."
+
+"I didn't mean that way," said Tom. "But I happen to be acquainted with
+an expert dye maker who lost some secret formulae during a fire in
+Field and Melling's factory."
+
+"You don't say so!" cried Mr. Blake. "Tom Swift, there's something
+wrong here! Let you and me talk this over. I begin to see how I may be
+able to take a peep through the hole in the grindstone," a colloquial
+expression which was as well understood by Tom as were some of Mr.
+Damon's blessing remarks.
+
+"If you're going to talk business I think I'll excuse myself," said
+Mary.
+
+"Don't go," urged Tom, but she said to him that she would see him
+before he left, and then she went out, leaving her uncle and the young
+inventor busily engaged in talking.
+
+But though Mr. Blake had certain suspicions regarding Field and
+Melling, and though Tom Swift, too, believed they had something to do
+with the disappearance of Baxter's secret formulae, it was another
+matter to prove anything.
+
+Impetuous as he often was, Mr. Blake was for calling in the police at
+once, and having the two men arrested. But Tom counseled delay.
+
+"Wait until we get more evidence against them," he urged.
+
+"But they may skip out!" objected Mary's uncle.
+
+"They won't with that Landmark Building on their hands," said the young
+inventor.
+
+"Their hands! Huh! They'll take precious good care that the trouble and
+responsibility of it are on other people's hands before they go,"
+declared Mr. Blake. "However, I suppose you're right. Barton Keith sets
+a deal by your opinion since that undersea search, and while I don't
+always agree with him, I do in this case. Especially since he is likely
+to have the laugh on me."
+
+"Oh, I wouldn't count everything lost in that building deal," said Tom.
+"A way may be found out of the trouble yet. But I must be getting back.
+Dr. Henderson was to give a report today on the condition of
+Eradicate's eyes, and I want to be there."
+
+"Mary was saying something about your faithful old retainer being in
+trouble," said Mr. Blake. "I'm sorry to hear about it."
+
+"We are all sorry for poor Rad," replied Tom slowly. "I only hope he
+gets his sight back. His last days will be very sad if he doesn't."
+
+Tom found Mary waiting for him after he had left her uncle, and, after
+a short talk with her, he made ready to ride back with Mr. Damon, who,
+after having attended to several other matters, was now outside in his
+car.
+
+"When are you coming home, Mary?" Tom asked.
+
+"In a week or two," she answered. "I'll send word when I'm ready and
+you can come and get me."
+
+"Delighted!" declared Tom. "Don't forget!" During the ride home the
+young inventor was unusually silent, so much so that Mr. Damon finally
+exclaimed:
+
+"Bless my phonograph, Tom Swift! but what is the matter? Has Mary
+broken the engagement?"
+
+"Oh, no, nothing like that," was the answer. "Only I'm wondering about
+Eradicate, and--other matters."
+
+Other matters had to do with what Mary's uncle had told Tom about the
+interest manifested by Field and Melling in some dye industry.
+
+Tom's forebodings regarding his colored helper were nearly borne out,
+for Dr. Henderson gloomily shook his head when asked for the verdict.
+
+"It's too early to say for a certainty," replied the medical man, "but
+I am not as hopeful as I was, Tom, I'm sorry to say."
+
+"I'm sorry to hear it," returned Tom. "Is there anything we can do--any
+hospital to which we can send him for special treatment?"
+
+"No, he is doing as well as he can be expected to right here. Besides,
+he has his friends around him, and the companionship of that giant of
+yours, absurd as it may seem, is really a tonic to Eradicate. I never
+saw such devotion on the part of any one."
+
+"Koku has certainly changed," said Tom. "He and Rad used always to be
+quarreling. But I guess that is all over," and Tom sighed.
+
+"Oh, I wouldn't say that," declared the medical man. "I haven't given
+up, though there are some symptoms I do not like. However, I am going
+to wait a week and then make another test."
+
+Tom knew that the week would be an anxious one for him, but, as it
+developed, he had so much to do in the next few days that, for the time
+being, he rather forgot about Eradicate.
+
+Field and Melling, he heard incidentally, had their machine towed to a
+garage for repairs, but beyond that no word came from the two men.
+Josephus Baxter remained at work over his dye formulae in one of Tom's
+laboratories, but the young inventor did not see much of the
+discouraged old man.
+
+Tom did not tell of the encounter with Field and Melling and of
+extinguishing the fire in their car, for he knew it would only excite
+Mr. Baxter, and do no good.
+
+It was within a few days of the time when Tom was to call in a
+committee of fire insurance experts to give them a demonstration of the
+efficiency of his aerial fire-fighting machine. He was putting the
+finishing touches to his craft and its extinguishing-dropping devices
+when he received a call from Mr. Baxter.
+
+"Well, how goes it?" asked Tom, trying to infuse some cheer into his
+voice.
+
+"Not very well," was the answer. "I've tried, in every way I know, to
+get on the track of the missing methods perfected by that Frenchman,
+but I can't. I'd be a millionaire now, if I had that dye information."
+
+"Do you really think they have them--actually have the formulae?" asked
+Tom.
+
+"I certainly do. And the reason I believe so is that I was over at a
+chemical supply factory the other day when an order came in for a
+quantity of a very rare chemical."
+
+"What has that to do with it?" asked Tom.
+
+"This chemical is an ingredient called for by one of the dye formulae
+that were stolen from me. I never heard of its being used for anything
+else. I at once became suspicious. I learned that this chemical had
+been ordered sent to Field and Melling in their new offices in the
+Landmark Building."
+
+"Maybe they intend to use it in making a new kind of fireworks,"
+suggested Tom.
+
+Mr. Baxter shook his head.
+
+"That chemical never would work in a skyrocket or Roman candle," he
+said. "I'm sure they're trying to cheat me out of my dye formulae. If I
+could only prove it!"
+
+"That's the trouble," agreed Tom. "But I'll give you all the help I
+can. And, come to think of it, I believe you might interest Mr. Blake.
+He has no love for Field and Melling, and he has several keen lawyers
+on his staff. I believe it would be a good thing for you to talk to Mr.
+Blake."
+
+"Please give me a letter of introduction to him," begged Mr. Baxter.
+"What I need is legal talent and capital to fight these scoundrels. Mr.
+Blake may supply both."
+
+"He may," agreed Tom. "I'll fix it so you can meet him. But what do you
+think of this combination, Mr. Baxter? It is my very latest solution
+for putting out fires. I'm loading an airship up with some of the bomb
+containers now, and--"
+
+Tom's further remarks were interrupted by the noise of shouting and
+tumult in the street, and a moment later yells could be heard of:
+
+"Fire! Fire! Fire!"
+
+"Another blaze!" exclaimed Mr. Baxter, raising the shades which had
+been drawn, since night had fallen.
+
+"And not far away," said Tom, as he caught the reflection of a red
+gleam in the sky.
+
+There was a ring at the front doorbell, and almost at once Ned Newton's
+voice called:
+
+"Tom! Tom Swift! There's quite a fire in town! Don't you want to try
+your new apparatus on it?"
+
+"The very chance!" exclaimed the young inventor. "Come on, Mr. Baxter.
+There's room in the airship for you and Ned. I want you to see how my
+chemical works!"
+
+Without waiting for a reply from the chemist, Tom caught him by the
+hand and led him toward the side door that gave egress to the yard
+where one of the airships was housed. Tom caught sight of Ned, who was
+hastening toward him.
+
+"Big fire, Tom!" said the young manager again. "Fierce one!"
+
+"I'm going to try to put it out!" Tom answered. "Want to come?"
+
+"Sure thing!" answered Ned.
+
+
+
+
+CHAPTER XVIII
+
+FINISHING TOUCHES
+
+
+Tom Swift and Ned Newton were so accustomed to acting quickly and in
+emergencies that it did not take them long to run out the airship,
+which Tom had in readiness, not especially for this emergency, but to
+demonstrate his new apparatus to a committee of fire underwriters whom
+he had invited to call in a few days.
+
+"Take this, if you will, Mr. Baxter!" cried Tom, giving the chemist a
+metal container. "It's a little different combination from the
+extinguisher I already have in the machine. Maybe I'll get a chance to
+try it."
+
+"You're going to have all the chance you want, Tom, by the looks of
+that blaze," commented Ned Newton.
+
+"It does look like quite a fire," observed Tom, as he gazed up at the
+sky, where the reflection was turning to a brighter red.
+
+Outside in the streets near the Swift house and shops could be heard
+the rattle of fire apparatus, the patter of running feet, and many
+shouts from excited men and boys.
+
+"Any idea what it is, Ned?" asked Tom, as he motioned to Mr. Baxter to
+climb into the aircraft.
+
+"Some one said it was the new Normal School. But that's farther to the
+north," was Ned's answer. "By the way the blaze has increased since I
+first saw it, I'd take it to be the lumberyard."
+
+"That would make a monster blaze!" observed Tom. "I don't believe I'll
+have chemicals enough for that," and he looked at the rather small
+supply in his craft. "However, I haven't time to get any more. Besides,
+they'll have the regular department on the job, and this isn't a
+skyscraper, anyhow."
+
+"No, we'll have to go to New York or Newmarket for one of those,"
+observed Ned. "All ready, Tom?"
+
+"All ready," said the young inventor, as Ned took his place beside Mr.
+Baxter.
+
+"What's the matter, Tom?" asked the voice of Mr. Swift, as he came out
+into the yard, having been attracted by the flashing lights and the
+noise of the aircraft motor, as Tom gave it a preliminary test.
+
+"There's a fire in town," Tom answered. "I'm going to see if they need
+my services."
+
+"Guess there isn't any question about that," said his business manager.
+
+Tom's father, who was suffering the infirmities of age, was in the
+habit of retiring early, and he had dozed off in his chair directly
+after supper, to be awakened by the shouting and confusion about the
+place.
+
+"Take care of yourself, my boy!" he advised, as there came a moment of
+silence before the throttle of the aircraft was opened to send it on
+its upward journey. "Don't take too many risks."
+
+"I won't," Tom promised. "We'll be back soon."
+
+Then came the roar of the motor as Tom cut out the muffler to gain
+speed and, a moment later, he and his two friends were sailing aloft
+with a load of fire-extinguishing chemicals.
+
+Up and up rose the aircraft. It was not the first time Mr. Baxter had
+enjoyed the sensation, but he was not enough of a veteran to be immune
+to the thrills nor to be altogether void of fear. And it was his first
+night trip. Still he gave few evidences of nervousness.
+
+"These she is!" cried Ned, for when the exhaust from the motor was sent
+through the new muffler Tom had attached it was possible to talk aboard
+the Lucifer. The young manager pointed down toward the earth, over
+which the craft was then skimming, though at no great height.
+
+"It is the lumberyard!" exclaimed Mr. Baxter presently.
+
+"It sure is," assented Tom. "I know I haven't enough stuff to cover as
+big a blaze as that, but I'll do my best. Fortunately there is no wind
+to speak of," he added, as he guided the craft in the direction of the
+fire.
+
+"What has that to do with it--I mean as far as the working of your
+chemical extinguisher is concerned?" asked Mr. Baxter. "Can't you drop
+the bomb containers accurately in a wind?"
+
+"Well, the wind has to be allowed for in dropping anything from an
+aeroplane," Tom answered. "And, naturally, it does spoil your aim to an
+extent. But the reason I'm glad there is no wind to speak of is that
+the chemical blanket I hope to spread over the fire won't be so quickly
+blown away."
+
+"Oh, I see," said Mr. Baxter. "Well, I'm glad that you will be able to
+have a successful test of your invention."
+
+"The regular land apparatus is on hand," observed Ned, for they were
+now so near the fire that they could look down and, in the reflection
+from the blaze, could see engines, hose-wagons and hook and ladder
+trucks arriving and deploying to different places of advantage, from
+which to fight the lumberyard fire that was now a roaring furnace of
+flames.
+
+"No skyscraper work needed here," observed Tom. "But it will give me a
+chance to use the latest combination I worked out. I'll try that first.
+Are you ready with it, Mr. Baxter?"
+
+"Yes," was the answer.
+
+The young inventor, not heeding the cries of wonder that arose from
+below and paying no attention to the uplifted hands and arms pointing
+to him, steered his craft to a corner of the yard where there was a
+small isolated fire in a pile of boards. It was Tom's idea to try his
+new chemical first on this spot to watch the effect. Then he would turn
+loose all his other containers of the chemical mixture that had proved
+so effective in other tests.
+
+Attention of those who had gathered to look at the fire was about
+evenly divided between the efforts of the regular department and the
+pending action by Tom Swift. The latter was not long in turning loose
+his latest sensation.
+
+"Let it go!" he cried to Mr. Baxter, and down into the seething caldron
+of flame dropped a thin sheet-iron container of powerful chemicals.
+Leaning over the cockpit of the aircraft, the occupants watched the
+effect. There was a slight explosion heard, even above the roar of the
+flames, and the tongues of fire in the section where Tom's extinguisher
+had fallen died down.
+
+"Good work!" cried Ned.
+
+"No!" answered Tom, shaking his head. "I was a little afraid of this.
+Not enough carbon dioxide in this mixture. I'll stick to the one I
+found most effective." For the flames, after momentarily dying down,
+burst out again in the spot where he had dropped the bomb.
+
+Tom wheeled the airship in a sharp, banking turn, and headed for the
+heart of the fire in the lumberyard. It was clearly getting beyond the
+control of the regular department.
+
+"How about you, Ned?" called Tom, for he had given his chum charge of
+dropping the regular bombs containing a large quantity of the
+extinguisher Tom had practically adopted.
+
+"All ready," was the answer.
+
+"Let 'em go!" came the command, and down shot the dark, spherical
+objects. They burst as they hit the ground or the piles of blazing
+lumber, and at once the powerful gases generated by the mixture of
+several different chemicals were released.
+
+Again the three in the airship leaned eagerly over the side of the
+cockpit to watch the effect. It was almost magical in its action.
+
+The bombs had been dropped into the very fiercest heart of the fire,
+and it was only an instant before their action was made manifest.
+
+"This will do the trick!" cried Ned. "I'm certain it will."
+
+"I didn't have much fear that it wouldn't," said Tom. "But I hoped the
+other would be better, for it is a much cheaper mixture to make, and
+that will count when you come to sell it to big cities."
+
+"But the fire is certainly dying down," declared Mr. Baxter.
+
+And this was true. As container after container of the bomb type fell
+in different parts of the burning lumberyard, while Tom coursed above
+it, the flames began to be smothered in various sections.
+
+And from the watching crowds, as well as from the hard-working members
+of the Shopton fire department, came cheers of delight and
+encouragement as they saw the work of Tom Swift's aerial fire-fighting
+machine.
+
+For he had, most completely, subdued what threatened to be a great
+fire, and when the last of his bombs had been dropped, so effective was
+the blanket of fire-dampening gases spread around that the flames just
+naturally expired, as it were.
+
+As Tom had said, the absence of wind was in his favor, for the
+generated gases remained just where they were wanted, directly over the
+fire like an extinguishing blanket, and were not blown aside as would
+otherwise have been the case.
+
+And, by the peculiar manner in which his chemicals were mixed, Tom had
+made them practically harmless for human beings to breathe. Though the
+fire-killing gases were unpleasant, there was no danger to life in
+them, and while several of the firemen made wry faces, and one or two
+were slightly ill from being too close to the chemicals, no one was
+seriously inconvenienced.
+
+"Well, I guess that's all," said Tom, when the final bomb had been
+dropped. "That was the last of them, wasn't it, Ned?"
+
+"Yes, but you don't need any more. The fire's out--or what isn't can be
+easily handled by the hose lines."
+
+"Good!" cried Tom. "But, all the same, I wish I had been able to make
+the first mixture work."
+
+"Perhaps I can help you with that," suggested Mr. Baxter.
+
+And the following day, after Tom had received the thanks of the town
+officials and of the fire department for his work in subduing the
+lumberyard blaze, the young inventor called Josephus Baxter in
+consultation.
+
+"I feel that I need your help," said the young inventor. "You have been
+at this chemical study longer than I, and I am willing to pay you well
+for your work. Of course I can't make up to you the loss of your dye
+formulae. But while you are waiting for something to turn up in regard
+to them, you may be glad to assist me."
+
+"I will, and without pay," said the chemist.
+
+But Tom would not hear of that, and together he and Mr. Baxter set
+about putting the finishing touches to Tom's latest invention.
+
+
+
+
+CHAPTER XIX
+
+ON THE TRAIL
+
+
+"There, Tom Swift, it ought to work now!"
+
+Josephus Baxter held up a large laboratory test tube, in which seethed
+and bubbled some strange mixture, turning from green to purple, then to
+red, and next to a white, milky mixture.
+
+"Do you think you've hit on the right combination?" asked the young
+inventor, whose latest idea, the plan of fighting fires in skyscrapers
+from an airship as a vantage point, was taking up all his spare moments.
+
+"I'm positive of it," said Mr. Baxter. "I've dabbled in chemicals long
+enough to be certain of this, even if I can't get on the track of the
+missing dye formulae."
+
+"That certainly is too bad," declared Tom. "I wish I could help you as
+much as you have helped me."
+
+"Oh, you have helped me a lot," said the chemist. "You have given me a
+place to work, much better than the laboratory I had in the old
+fireworks factory of Field and Melling. And you have paid me, more than
+liberally, for what little I have done for you."
+
+"You've done a lot for me," declared Tom. "If it had not been for your
+help this chemical compound would not be nearly as satisfactory as it
+is, nor as cheap to manufacture, which is a big item."
+
+"Oh, you were on the right track," said Mr. Baxter. "You would have
+stumbled on it yourself in a short time, I believe. But I will say, Tom
+Swift, that, between us, we have made a compound that is absolutely
+fatal to fires. Even a small quantity of it, dropped in the heart of a
+large blaze, will stop combustion."
+
+"And that's what I want," declared Tom. "I think I shall go ahead now,
+and proceed with the manufacture of the stuff on a large scale."
+
+"And what do you propose doing with it?" asked Mr. Baxter.
+
+"I'm going to sell the patent and the idea that goes with it to as many
+large cities as I can," Tom answered. "I'll even manufacture the
+airships that are needed to carry the stuff over the tops of blazing
+skyscrapers, dropping it down. I'll supply complete aerial
+fire-fighting plants."
+
+"And I think you'll do a good business," said the chemist.
+
+It was the conclusion of the final tests of an improved chemical
+mixture, and the reaction that had taken place in the test tube was the
+end of the experiment. Success was now again on the side of Tom Swift.
+
+But when that has been said there remains the fact that it was just the
+other way with the unfortunate Mr. Baxter.
+
+Try as he had, he could not succeed in getting the right chemical
+combination to perfect the dye process imparted to him by his late
+French friend. With the disappearance of the secret formulae went the
+good luck of Josephus Baxter.
+
+He had worked hard, taking advantage of Tom's generosity, to bring back
+to his memory the proper manner of mixing certain ingredients, so that
+permanent dyes of wondrous beauty in coloring would be evolved. But it
+was all in vain.
+
+"I know who have those formulae," declared the chemist again and again.
+"It is those scoundrels, Field and Melling. And they are planning to
+build up their own dye business with what is mine by right!"
+
+And though Tom, also, believed this, there was no way of proving it.
+
+As the young inventor had said, he was now ready to put his own latest
+invention on the market. After many tests, aided in some by Mr. Baxter,
+a form of liquid fire extinguisher had been made that was superior to
+any known, and much cheaper to manufacture. Veteran members of fire
+departments in and about Shopton told Tom so. All that remained was to
+demonstrate that it would be as effective on a large scale as it was on
+a small one, and big cities, it was agreed, must, of necessity, add it
+to their equipment.
+
+"Well, I think I'll give orders to start the works going," said Tom, at
+the conclusion of the final test. "I have all the ingredients on hand
+now, and all that remains is to combine them. My airship is all ready,
+with the bomb-dropping device."
+
+"And I wish you all sorts of luck," said Mr. Baxter. "Now I am going to
+have another go at my troubles. I have just thought of a possible new
+way of combining two of the chemicals I need to use. It may be I shall
+have success."
+
+"I hope so," murmured Tom. He was about to leave the room when Koku,
+the giant, entered, with a letter in his hand. The big man showed some
+signs of agitation, and Tom was at once apprehensive about Eradicate.
+
+"Is Rad--has anything happened--shall I get the doctor?"
+
+"Oh, Rad, him all right," answered Koku. "That is him not see yet, but
+mebby soon. Only I have to chase boy, an' he make faces at me--boy
+bring this," and the giant held out the envelope.
+
+"Oh!" exclaimed Tom, and he understood now. Messenger boys frequently
+came to Tom's house or to the shops, and they took delight in poking
+fun at Koku on account of his size, which made him slow in getting
+about. The boys delighted to have him chase them, and something like
+this had evidently just taken place, accounting for Koku's agitation.
+
+"This is for you, Mr. Baxter, not for me," said Tom, as he read the
+name on the envelope.
+
+"For me!" exclaimed the chemist. "Who could be writing to me? It's a
+big firm of dye manufacturers," he went on, as he caught a glimpse of
+the superscription in the upper left hand corner.
+
+Quickly he read the contents of the epistle, and a moment later he gave
+a joyful cry.
+
+"I'm on the trail! On the trail of those scoundrels at last!" exclaimed
+Josephus Baxter. "This gives me just the evidence I needed! Now I'll
+have them where I want them!"
+
+
+
+
+CHAPTER XX
+
+A HEAVY LOAD
+
+
+Josephus Baxter was so excited by the receipt of the letter which Koku
+delivered to him that for some seconds Tom Swift could get nothing out
+of him except the statement:
+
+"I'm on their trail! Now I'm on their trail!"
+
+"What do you mean?" Tom insisted. "Whose trail? What's it all about?"
+
+"It's about Field and Melling! That's who it's about!" exclaimed Mr.
+Baxter, with a smothered exclamation. "Look, Tom Swift, this letter is
+addressed to me from one of the biggest dye firms in the world--a firm
+that is always looking for something new!"
+
+"But if you haven't anything new to give them, of what use is it?" Tom
+asked, for he knew that the chemist had said his process, stolen, as he
+claimed, by Field and Melling, was his only new project.
+
+"But I will have something new when I get those secret formulae away
+from those scoundrels!" declared Mr. Baxter.
+
+"Yes, but how are you going to do it, when you can't even prove that
+they have them?" asked Tom.
+
+"Ah, that's the point! Now I think I can prove it," declared Mr.
+Baxter. "Look, Tom Swift! This letter is addressed to me in care of
+Field and Melling at the office I used to have in their fireworks
+factory."
+
+"The office from which you were rescued nearly dead," Tom added.
+
+"Exactly. The place where you saved me from a terrible death. Well, if
+you will notice, this letter was written only two days ago. And it is
+the first mail I have received as having been forwarded from that
+address since the fire. I know other mail must have come for me,
+though."
+
+"What became of it?" asked Tom.
+
+"Those scoundrels confiscated it!" declared the chemist. "But, in some
+manner, perhaps through the error of a new clerk, this letter was
+remailed to me here, and now I have it. It is of the utmost importance!"
+
+"In what way?" asked Tom.
+
+"Why, it is directed to me, outside and in, and it makes an inquiry
+about the very dyes of the lost secret formulae, one dye in particular."
+
+"I don't quite understand yet," said Tom.
+
+"Well, it's this way," went on Mr. Baxter. "I had, in the office of
+Field and Melling, all the papers telling exactly how to make the dyes.
+After the fire, in which I was rendered unconscious, those papers
+disappeared.
+
+"The only way in which any one could make the dyes in question was by
+following the formulae given in those papers. And now here is a letter,
+addressed to me from a big firm, asking my prices on a certain dye,
+which can only be made by the process bequeathed to me by the
+Frenchman."
+
+"Which means what?" asked Tom.
+
+"It means that Field and Melling must have been writing to this firm on
+their own hook, offering to sell them some of this dye. But, in some
+way, my name must have appeared on the letter or papers sent on by the
+scoundrels, and this big firm replies to me direct, instead of to Field
+and Melling! Even then I would not have benefited if they had
+confiscated this letter as I am sure, they have done in the case of
+others. But, by some slip, I get this.
+
+"And it proves, Tom Swift, that Field and Melling are in possession of
+my dye formulae, and that they have tried to dispose of some of the dye
+to this firm. Not knowing anything of this, the firm replies to me. So
+now I have direct evidence--just what I wanted--and I can get on the
+trail of the scoundrels who have cheated me of my rights."
+
+Tom looked at the letter which, it appeared, had been left with Koku by
+a special delivery boy from the post office. It was an inquiry about
+certain dyes, and was addressed to Mr. Baxter in care of Field and
+Melling, the former fireworks firm, which now had started a big dye
+plant, with offices in the Landmark Building in Newmarket.
+
+"It does look as though you might get at them through this," Tom said,
+as he handed back the letter. "But I'm afraid you'll have to get
+further evidence before you could convict them in a court of
+law--you'll have to show that they actually have possession of your
+formulae."
+
+"That's what I wish I could do," said the chemist, somewhat wistfully.
+His first enthusiasm had been lessened.
+
+"I'll help you all I can," offered Tom. And events were soon to
+transpire by which the young inventor was to render help to the chemist
+in a most sensational manner.
+
+"Just now," Tom went on, "I must arrange about getting a large supply
+of these chemicals made, and then plan for a test in some big city."
+
+"Yes, you have done enough for me," said Mr. Baxter. "But I think now,
+with this letter as evidence, we'll be able to make a start."
+
+"I agree with you," Tom said. "Why don't you go over to see Mr. Damon?
+He's a good business man, and perhaps he can advise you. You might
+also call on that lawyer who does work for Mr. Keith and Mr. Blake. And
+that reminds me I must call Mary Nestor up and find out when she is
+coming home. I promised to fetch her in one of the airships."
+
+"I will go and see Mr. Damon," decided Mr. Baxter. "He always gives
+good advice."
+
+"Even if he does bless everything he sees!" laughed Tom. "But if you're
+going to see him I'll run you over. I'm going to Waterfield."
+
+"Thanks, I'll be glad to go with you," said the chemist.
+
+Mr. Damon was glad to see his friends, and, when he had listened to the
+latest developments, he exclaimed with unusual emphasis:
+
+"Bless my law books, Mr. Baxter! but I do believe you're on the right
+trail at last. Come in, and we'll talk this over."
+
+So Tom left them, traveling on to a distant city where he arranged for
+a large supply of the chemicals he would need in his extinguisher.
+
+For several days Tom was so busy that he had little time to devote to
+Mr. Baxter, or even to see him. He learned, however, that the chemist
+and Mr. Damon were in frequent consultation, and the young inventor
+hoped something would come of it.
+
+Tom's own plans were going well. He had let several large cities know
+that he had something new in the way of a fire-fighting machine, and he
+received several offers to demonstrate it.
+
+He closed with one of these, some distance off, and agreed to fly over
+in his aircraft and extinguish a fire which was to be started in an old
+building which had been condemned, and was to be destroyed. This was in
+a city some four hundred miles away and when Ned Newton called on him
+one afternoon he found Tom busily engaged in loading his sky-craft with
+a heavy cargo of the newest liquid extinguisher.
+
+"You aren't taking any chances, are you, Tom?" asked Ned.
+
+"What do you mean?"
+
+"I mean you seem to have enough of the liquid 'fire-discourager' to
+douse any blaze that was ever started."
+
+"No use sending a boy on a man's errand," said Tom. "I'm counting on
+you to go with me, Ned--you and Mr. Baxter. We leave this afternoon for
+Denton."
+
+"I'll be with you. Couldn't pass up a chance like that. But here comes
+Koku, and it looks as if he had something on his mind."
+
+The giant did, indeed, seem to be laboring under the stress of some
+emotion.
+
+"Oh, Master Tom!" the big man exclaimed when he had got the attention
+of the young inventor. "Rad--he--he--"
+
+"Has anything happened?" asked Tom, quickly. "No, not yet. But dat pill
+man--he say by tomorrow he know if Rad ever will see sunshine more!"
+
+"Oh, the doctor says he'll be able to decide about Rad's eyesight
+tomorrow, does he?"
+
+"Yes. What so pill man say," repeated Koku.
+
+"Um," mused Tom, "I wish I were going to be here, but I don't see how I
+can. I must give this test." But it was with a sinking heart as he
+thought of poor Eradicate that the young inventor proceeded to pile
+into his airship the largest and heaviest load of chemicals it had ever
+carried.
+
+
+
+
+CHAPTER XXI
+
+THE LIGHT IN THE SKY
+
+
+"Well, what do you say, Tom?" asked Ned, in a low voice.
+
+"She's all right as far as I can see, though she may stagger a bit at
+the take off."
+
+"It's a pretty heavy load," agreed the young manager, as he and Tom
+Swift walked about the big fire-fighting airship Lucifer, which had
+been rolled outside the hangar. "But still I think she'll take it,
+especially since you've tuned up the motor so it's at least twenty per
+cent. more powerful than it was."
+
+"Perhaps you'd better leave me out," suggested Mr. Baxter, who had been
+helping the boys. "I'm not a feather weight, you know."
+
+"I need you with us," said Tom. "I want your expert opinion on the
+effect the new chemicals have on the flames."
+
+"Well, I'd like to come," admitted the chemist, "for it will be a
+valuable experience for me. But I don't want an accident up in the air."
+
+"Trust Tom Swift for that!" cried Ned. "If he says his aircraft will do
+the trick, it positively will."
+
+"How about leaving me out?" asked Mr. Damon. "I'm not an expert in
+anything, as far as I know."
+
+"You are in keeping us cheerful. And we may need you to bless things if
+there's a slip-up anywhere," laughed Tom, for Mr. Damon had been
+invited to be one of the party.
+
+"I don't so much mind a slip-up," said Mr. Damon, "as I do a slip down.
+That's where it hurts! However, I'll take a chance with you, Tom Swift.
+It won't be the first one--and I guess it won't be the last."
+
+The work of getting the big airship ready for what was to be a
+conclusive test of her fire-fighting abilities from the clouds
+proceeded rapidly. As has been related, Tom had perfected, with the
+help of Mr. Baxter, a combination of chemicals which was effective in
+putting out a fire when dropped into the blaze from above. Quantities
+of this combination had been stored in metal containers which Tom had
+at first styled "bombs," but which he now called "aerial grenades."
+
+The manner of dropping the grenades was, on the whole, similar to the
+manner in which bombs were dropped from airships during the Great War,
+but Tom had made several improvements in this plan.
+
+These improvements had to do with the releasing of the bombs, or, in
+this case, grenades. It is not easy to drop or throw something from a
+swiftly moving airship so that it will hit an object on the ground.
+During the war aviators had to train for some time before becoming even
+approximately accurate.
+
+Tom Swift decided that to leave this matter to chance or to the eye of
+the occupant of an airship was too indefinite. Accordingly he invented
+a machine, something like a range-finder for big guns. With this it was
+a comparatively easy matter to drop a grenade at almost any designated
+place.
+
+To accomplish this it was necessary to take into consideration the
+speed of the airship, its height above the ground, the velocity of the
+wind, the weight of the grenades, and other things of this sort. But by
+an intricate mathematical process Tom solved the problem, so that it
+was only necessary to set certain pointers and levers along a slide
+rule in the cockpit of the craft. Then when the releasing catch was
+pressed, the grenades would drop down just about where they were most
+needed.
+
+"I think everything is ready," said Tom, when he had taken a last look
+over his craft, making sure that all the chemical grenades were in
+place. "If you will be ready, gentlemen, we will take our places and
+start in about half an hour," he added. "I want to say goodbye to my
+father, and cheer up Rad--if I can."
+
+"The doctor will know tomorrow, will he?" asked Mr. Damon.
+
+"Yes. And I'm sorry I will not be here to listen to the report," said
+Tom. "Though I am almost afraid to receive it," he added in a low
+voice. "I shall blame myself if Rad is to go through the remainder of
+his life blind."
+
+"It couldn't be helped," said Ned. "We'll hope for the best."
+
+"Yes," agreed Tom, "that's all we can do--hope for the best. By the
+way," he went on, turning to Mr. Baxter, "are you any nearer fastening
+the guilt on those two rascals, Field and Melling?"
+
+"Bless my prosecuting attorney, no!" exclaimed Mr. Damon. "Those are
+the slickest scoundrels I ever tackled! They're like a flea. Once you
+think you have them where you want them, and they're on the other side
+of the table, skipping around."
+
+"I've about given up," said Mr. Baxter, in discouraged tones. "I guess
+my dye formulae are gone forever."
+
+"Don't say that!" exclaimed Tom. "Once I get this fire matter off my
+hands, I'm going to tackle the problem myself. We'll either make those
+fellows sorry they ever meddled in this matter, or we'll get up a new
+combination of dyes that will put them out of business!"
+
+"Bless my Easter eggs, I'm glad to hear you talk that way!" cried Mr.
+Damon.
+
+"Well, Rad, I'll expect to see you up and around when I get back," said
+Tom to his old servant, as he stepped into the sick room to say goodbye.
+
+"Oh, is yo' goin', Massa Tom?" asked the colored man, turning his
+bandaged head in the direction of the beloved voice.
+
+"Yes. I'm going to try out a new scheme of mine--the fire extinguisher,
+you know."
+
+"De same one whut fizzed up, an'--an' busted me in de eyes, Massa Tom?"
+
+"Yes, Rad, I'm sorry to say, it's the same one."
+
+"Oh, shucks now, Massa Tom! whut's use worryin'?" laughed Rad. "I suah
+will be all right when yo' gits back. De doctor man--de 'pill man' dat
+giant calls him--says I'll suah be better."
+
+"Of course you will," declared Tom, but his heart sank when he saw Mrs.
+Baggert remove the bandages and he caught sight of Rad's burned face
+and the eyes that had to be kept closed if ever they were again to look
+on the sunshine and flowers. "And when I come back, Rad, I'll stage a
+little fire for your benefit, and show you how quickly I can put it
+out."
+
+"Ha! dat's whut I wants to see, Massa Tom, I suah does like to see
+fires!" chuckled Eradicate. "Mah ole mule, Boomerang--does yo' 'member
+him, Massa Tom?"
+
+"Of course, Rad!"
+
+"Well, Boomerang he liked fires, too. Liked 'em so much I jest couldn't
+git him past 'em lots ob times I But run 'long, Massa Tom. Yo' ain't
+got no time to waste on an ole culled man whut's seen his best days.
+Yas-sir, I reckon I'se seen mah best days," and the smile died from the
+honest, black face.
+
+"Oh, don't talk like that!" cried Tom, as cheerfully as he could.
+"You've got a lot of work in you yet, Rad. Hasn't he, Koku?" and the
+young inventor appealed to the giant, who seldom left the side of his
+former enemy.
+
+"Rad good man--him an' me do lots work--next week mebby," said Koku,
+smiling very broadly.
+
+"That's the way to talk!" exclaimed Tom, and he laughed a little though
+his heart was far from light.
+
+And then, having seen to the final details, he took his place in the
+big airship with Ned, Mr. Damon and Josephus Baxter. The craft carried
+the largest possible load of fire extinguishing chemicals.
+
+As Tom had feared, the Lucifer staggered a bit in "taking off" late
+that afternoon when the start was made for the distant city of Denton,
+where the first real test was to be made under the supervision and
+criticism of the fire department. But once the craft was aloft she rode
+on a level keel.
+
+"I guess we're all right," Tom said. But to make certain he circled
+several times over his own landing field, that a good place to come
+down might be assured if something unforeseen developed.
+
+However, all went well, and then the course was straightened for the
+distant city.
+
+"We'll go right over Newmarket, sha'n't we, Tom?" asked Ned, as the
+speed of the Lucifer increased.
+
+"Yes. And I wish I had time to stop and see Mary, but I haven't. It's
+getting dark fast, and we ought to arrive at our destination early in
+the morning. The test has been set by the committee for ten o'clock."
+
+They settled themselves comfortably in the big craft for a long night
+trip, and Mr. Damon was just going to bless something or other when he
+pointed off into the distance.
+
+"Look, Tom!" cried the eccentric man. "See that light in the sky!"
+
+"Seems to be a fire," observed Ned.
+
+"It is a fire!" shouted Mr. Baxter. "And it's in Newmarket, if I'm any
+judge."
+
+Tom Swift did not answer, but he shoved forward the gasolene lever of
+his controls, and the Lucifer shot ahead through the air while the red,
+angry glow deepened in the evening sky.
+
+
+
+
+CHAPTER XXII
+
+TRAPPED
+
+
+While Tom Swift was loading the Lucifer for her trip and the fire
+extinguishing test to occur the next morning, quite a different scene
+was taking place in the home of Jasper Blake, the uncle of Mary Nestor,
+where she had gone to spend a few weeks.
+
+"Well, are you all ready, Mary?" asked her aunt, and it was about the
+same time that Ned Newton asked that same question of Tom Swift. Only
+Tom was in Shopton, and Mary was in Newmarket, and Tom was setting off
+on an air voyage, while Mary was only preparing to take a car downtown
+to do some shopping.
+
+"Yes, Aunt, I'm all ready," Mary answered. "But I may be a bit late
+getting home."
+
+"Why?" asked Mrs. Blake.
+
+"I promised Uncle Barton I'd stop and call on him at his office," Mary
+replied. "He has something he wants me to take home to mother when I go
+tomorrow."
+
+"I shall be sorry to see you go back," said Mrs. Blake. "But I imagine
+there will be those in Shopton who will be glad to see you return,
+Mary."
+
+"Yes, mother wrote that she and dad were getting a bit lonesome," the
+girl casually replied, as she adjusted her veil.
+
+"Yes, and some one else. Ah, Mary, you are a very lucky girl!" laughed
+her aunt, while Mary turned aside so she would not see her own blushes
+in the mirror.
+
+"I thought Tom was going to call and take you home in his airship,
+Mary," went on her relative.
+
+"So he is, I believe, on his way back from a city where he is going to
+be tomorrow making a big fire test. I am to wait for him until tomorrow
+afternoon. But now I really must go shopping, or all the bargains will
+be taken. Is there any word you want to send to Uncle Barton?"
+
+"No," answered Mrs. Blake. "Though you might tell him to stop poking
+fun at your Uncle Jasper for having invested money in the Landmark
+Building. It's getting on your Uncle Jasper's nerves," she added.
+
+"Uncle Barton never can give up a joke, once he thinks he has one,"
+said Mary. "But I'll tell him to stop pestering Uncle Jasper."
+
+"Please do," urged Mary's aunt, and then the girl left.
+
+Mary's uncle, Barton Keith, with whom Tom Swift had been associated
+during the undersea search, had offices in the Landmark Building, but
+his home was in an adjoining suburb.
+
+The girl was pleased with the results of her shopping, and at the close
+of the afternoon she stopped at the Landmark Building and was soon
+being shot up in the elevator to the floor where Barton Keith had his
+offices.
+
+Though Mr. Keith had refrained from investing in the Landmark Building
+and though he laughed at Mary's Uncle Jasper for having done so, this
+did not prevent him from having a suite of offices in the big structure
+which, as we already know, was owned in large part by Field and Melling.
+
+"Ah, Mary! Come in!" exclaimed Mr. Keith, welcoming Tom Swift's
+sweetheart. "It is so late I was afraid you weren't coming, and I was
+about to close the office and go home."
+
+"You must blame the bargain sales for my delay," laughed Mary. "I hope
+I haven't kept you waiting."
+
+"No, I still had a few things to do. One was to write a letter to your
+Uncle Jasper, telling him I had heard of another fire trap that was
+open to investors."
+
+"Oh, and that reminds me I must tell you not to push Uncle Jasper too
+far!" warned Mary.
+
+"Ha! Ha!" laughed Uncle Barton. "He made fun of me for going on the
+undersea search with Tom Swift. But I made good on that, and that's
+more than he can say about his Landmark Building deal!"
+
+"But don't exasperate him too much!" begged Mary. "By the way, what are
+they doing to this building? I see the stairways and some of the
+elevator shafts all littered with building material."
+
+"They are trying to make it fireproof," answered her uncle. "It's
+rather late to try that now, but they've got either to do it or stand a
+big increase in insurance rates. I'm glad I'm out of it. But now, Mary,
+take an easy chair until I finish some work, and then I'll walk out
+with you."
+
+Mary took a seat near one of the front windows, whence she could look
+down into the now fast-darkening streets. She could see the supper
+crowds hurrying home, and out in the corridor of the big skyscraper
+could be heard the banging of elevator doors as the office tenants, one
+after another, left for the day.
+
+Suddenly there was more commotion than usual, followed by the sound of
+broken glass. Then came a cry of:
+
+"Fire! Fire!"
+
+Mary sprang to her feet with a gasp of alarm, and her uncle rushed past
+her to the door leading into the hall outside his offices. As he opened
+the door a cloud of smoke rushed toward him and Mary, causing them to
+choke and gasp.
+
+Mr. Keith closed the door a moment, and when he opened it again the
+smoke in the hall seemed less dense.
+
+"It probably is only a slight blaze among some of the material the
+workmen are using," he said. "Come, Mary, we'll get out."
+
+Pausing only to swing shut the door of his heavy safe and to stuff some
+valuable papers into his pocket, Mr. Keith advanced and, taking Mary by
+the arm, led her into the hall. The smoke was increasing again, and
+distant shouts and cries could be heard, mingled with the breaking of
+glass.
+
+Mr. Keith rang the elevator buzzer several times, but when no car came
+up the shaft in response to his summons he turned to his niece and said:
+
+"We'll try the stairs. It's only ten stories down, and going down isn't
+anything like coming up."
+
+"Oh, indeed I can walk!" said Mary. "Let's hurry out!"
+
+They turned toward the stairway, which wound around the elevator
+shafts, but such a cloud of hot, stifling smoke rolled up that it sent
+them back, choking and gasping for breath.
+
+And then, as they stood there, up the elevator shafts, which were
+veritable chimneys, came more hot smoke, mingled with sparks of fire.
+
+"Trapped!" gasped Mr. Keith, and he pulled Mary back toward his offices
+to get away from the choking, stifling smoke. "We're trapped!"
+
+
+
+
+CHAPTER XXIII
+
+TO THE RESCUE
+
+
+"Uncle! Uncle Barton!" faltered Mary, as she clung to Mr. Keith. "Can't
+we get down the stairs?"
+
+"I'm afraid not, Mary," he answered, and he closed the door of his
+office to keep out the smoke that was ever increasing.
+
+"And won't the elevators come for us?"
+
+"They don't seem able to get up," was his reply. "Probably the fire
+started in the bottom of the shafts, and they act just like flues,
+drawing up the flames and smoke."
+
+"Then we must try the fire escapes!" exclaimed Mary, and she started
+toward the front window, pulling her uncle across the room after her.
+
+"Mary, there aren't--aren't any fire escapes!" he said hoarsely.
+
+"No fire escapes!" The girl turned paler than before.
+
+"No, not an escape as far as I know. You see, this was thought to be a
+fireproof building at first and small attention was given to escapes.
+Then the law stepped in and the owners were ordered to put up regular
+escapes. They have started the work, but just now the old escapes have
+been torn down and the new ones are not yet in place."
+
+"Oh, but Uncle Barton! can't we do something?" cried Mary. "There must
+be some way out! Let's try the elevators again, or the stairs!"
+
+Before Mr. Keith could stop her Mary had opened the door into the hall.
+To the agreeable surprise of her uncle there seemed to be less smoke
+now.
+
+"We may have a chance!" he cried, and he rushed out. "Hurry!"
+
+Frantically he pushed the button that summoned the elevators. Down
+below, in the elevator shafts, could be heard the roar and crackle of
+flames.
+
+"Let's try the stairs!" suggested Mary. "They seem to be free now."
+
+She started down the staircase which went in square turns about the
+battery of elevators, and her uncle followed. But they had not more
+than reached the first landing when a roll of black, choking smoke,
+mingled with sparks of fire, surged into their faces.
+
+"Back, Mary! Back!" cried Mr. Keith, and he dragged the impetuous girl
+with him to their own corridor, and back into his offices which, for
+the time being, were comparatively free from the choking vapor.
+
+"We must try the windows, Uncle Barton! We must!" cried Mary. "Surely
+there is some way down--maybe by dropping from ledge to ledge!"
+
+Her uncle shook his head. Then he opened the window and looked out. As
+he did so there arose from the streets below the cries of many voices,
+mingled with the various sounds of fire apparatus--the whistles of
+engines, the clang of gongs, and the puffing of steamers.
+
+"The firemen are here! They'll save us!" cried Mary, as she heard the
+noises in the street below. "We can leap into the life nets."
+
+"There isn't a life net made, nor men who could retain it, to hold up a
+person jumping from the tenth story," said her uncle. "Our only chance
+is to wait for them to subdue the fire."
+
+"Isn't there a back way down, Uncle Barton?" "No, Mary!" He closed the
+window for, open as it was, the draft created served to suck smoke into
+the office, and Mary was coughing.
+
+Uncle and niece faced each other. Trapped indeed they were, unless the
+fire, which was now raging all through the building, with the stairs
+and elevator shafts as a center, could be subdued. That the city fire
+department was doing its best was not to be doubted.
+
+"We can only wait--and hope," said Mr. Keith solemnly.
+
+Mary gave a gasp. Her uncle thought she was going to burst into tears,
+but she bravely conquered herself and faced him with what was meant to
+be a smile. But it is difficult to smile with quivering lips, and Mary
+soon gave up the attempt.
+
+Mr. Keith went over to the water cooler--one of those inverted large
+glass bottles--and looked to see how much water it contained.
+
+"It's nearly full," he said.
+
+"What good will it do?" asked Mary. "This fire is beyond a little water
+like that."
+
+"Yes, but it will serve to keep our handkerchiefs wet so we can breathe
+through them if the smoke gets too thick," was his reply.
+
+"It begins to look as if we'd need to try that soon," said Mary, and
+she pointed to thick smoke curling in under the door.
+
+"Yes," agreed her uncle. "It's getting worse." Hardly had he spoken
+when there came a rush of feet in the corridor outside his office door.
+Then a voice exclaimed:
+
+"We're trapped! We can't get down either the stairs or the elevators!"
+
+"It can't be possible!" said another voice. "Something must be done!
+Help! Help! Take us out of here!"
+
+"Foolish cowards!" murmured Mr. Keith, and then the door of his office
+was violently opened and two men rushed in. They were strangers to Mary
+and her uncle.
+
+"Isn't there any way out of this fire trap?" cried one of the men. "Are
+there any fire escapes at your windows?"
+
+"None," said Mr. Keith.
+
+"This is all your fault, Melling!" cried the smaller of the two men,
+whose voice, in loudness and depth of pitch, was out of all proportion
+to his size. "All your fault! I told you we should have those new fire
+escapes!"
+
+"And you were the one, Field, who objected to the cost of fire escapes
+when you found what the charge would be," retorted the other. "You said
+we didn't need to waste that money, if the building was fire-proof."
+
+"But it isn't, Melling! It isn't!" yelled the other.
+
+"We're finding that out too late!" came the retort. "But I'm not going
+to die here like a rat in a trap!" And he raised the window and leaned
+out and yelled, "Help! Help! Help!"
+
+"Don't do that," said Mr. Keith, coming over to close the casement.
+"They can't hear you down below, and opening the window will only fill
+this place with smoke. Are you Field and Melling?"
+
+"Yes, of the Consolidated Dye Company," was the answer from the big
+man. "We are also part owners of this building, but I wish we weren't."
+
+"It is a pretty poor specimen of a modern building," said Mr. Keith.
+"You have offices here, haven't you?" he went on. "I remember to have
+seen your names on the directory."
+
+"We're on the floor above," was the answer from Field. "We were in a
+rear room, going over some accounts, and we didn't know anything was
+wrong until we smelled smoke. We tried to get down, and managed to
+come, by way of the stairs, as far as this floor," he explained quickly.
+
+"You can't go any farther," said Mr. Keith. "All there is to do is to
+wait for the firemen."
+
+"Suppose they never come?" whined Melling. "Oh, they'll come!" asserted
+Mary's uncle, but he spoke more to quiet her alarm than because he
+really believed it, for the Landmark Building was a seething furnace of
+flame centering in and about the elevator shafts and stairs.
+
+Meanwhile Tom and his companions in the airship had seen the red glow
+in the evening sky, and in another minute the young inventor had turned
+his craft more directly toward it.
+
+"It surely is in Newmarket," said Mr. Damon. "Right in the center of
+the city, too. There's one big building there--the Landmark."
+
+"Looks as if that was afire," said Ned quickly. "Hasn't some relative
+of Mary's an office there, Tom?"
+
+"Yes. Mr. Keith. And her other uncle, Jasper Blake, is also interested
+in the building. It's the Landmark all right!" cried Tom, as his craft
+rose higher and advanced nearer the blaze.
+
+"What are you going to do?" yelled Mr. Damon, as he saw the young
+inventor head directly toward a spouting mushroom of flame, which
+showed that the fire had broken through the roof. "What are you going
+to do?"
+
+"Go to the rescue!" answered Tom Swift. "I couldn't ask a better
+opportunity to try my new extinguisher! Sit tight, every one!"
+
+
+
+
+CHAPTER XXIV
+
+A STRANGE DISCOVERY
+
+
+Once it became evident to the occupants of the airship what Tom Swift's
+plans were, they all prepared to help him. Previous to the trip certain
+duties had been assigned to each one, duties which were to be exercised
+when Tom gave the exhibition of his new aerial fire-fighting apparatus
+at the set fire before the fire department of Denton.
+
+This preparation now stood the young inventor in good stead, for there
+was no confusion aboard the Lucifer when she winged her way toward the
+burning Landmark Building, where the flames were continually spouting
+higher and higher as they rushed through the roof, directly above the
+stairway well and elevator shafts.
+
+So far the flames had confined themselves to this central part of the
+big structure, but it was only a question of time when they would
+spread out on all sides, licking up the remainder of the pile. And, for
+the most part, the firemen on the ground were at a great disadvantage.
+
+They had run in lines as near as they could get to the center of the
+blaze, and had also attached hose to the standpipes inside the
+building. But this last effort was wasted, as developed later, for
+there was no one in the building to direct the nozzle ends of the hose
+attached to the standpipes on the different floors. Also the fierce
+heat fairly melted the pipes themselves in the vicinity of the elevator
+shafts, and there was no automatic sprinkling system in the building.
+
+This was the situation, then, when Tom in his airship loaded with
+fire-extinguishing chemicals headed for the blaze. And this, also, was
+the desperate situation that confronted Mary Nestor and her uncle,
+Barton Keith, as well as Amos Field and Jason Melling. Those
+unscrupulous and cowardly men were in a veritable panic of fear, which
+contrasted strangely with the calm, resigned attitude of Mary and her
+uncle.
+
+"We must get out! Some one must save us!" yelled Field.
+
+"Jump from the window!" cried Melling.
+
+"No, I can't permit that!" declared Mr. Keith, standing in their path.
+"It would be sure death! As it is, there may be a chance."
+
+"A chance? How?" asked Field. "Listen to that!"
+
+Through the closed door of Mr. Keith's office could be heard the roar
+and crackle of flames, while the very air was now stifling and hot,
+filled with acrid smoke.
+
+"We can only wait," said Mr. Keith, and he wet Mary's handkerchief in
+the water and handed it to her to bind over her face.
+
+"Is everything all right, Ned?" called Tom, as he turned on a little
+more power, so that the Lucifer lunged ahead toward the great pillar of
+fire that now reddened the sky for miles around.
+
+"All ready," was the answer. "You only have to give the word when you
+want us to let go."
+
+"Let go!" cried Mr. Damon. "Bless my umbrella, Tom! We don't have to
+jump out, do we?"
+
+"He means to let go the extinguisher grenades," said Mr. Baxter. "Shall
+we let them all go at once, Tom?" asked the chemist.
+
+"No, drop half when I shoot over the first time. We'll see what effect
+they have, and then come back with the rest."
+
+"That's the idea!" cried Ned. "Well, give us the word when you're
+ready, Tom."
+
+"I will," was the answer of the young inventor, and with keen eyes he
+began to set the automatic gages so those in charge of the grenades
+would be able to drop them most effectively.
+
+The flames were mounting higher and higher above the ill-fated Landmark
+Building. It was a "land-mark" now, for miles around--a fearsome mark,
+indeed.
+
+"I hope every one is out of the place," said Ned, as the airship
+approached nearer and the fierceness of the fire was more manifest.
+
+"Bless my thermometer, you're right!" exclaimed Mr. Damon. "I don't see
+how any one could live in that furnace."
+
+Seen from above it appeared that the fire was engulfing the whole
+building, while, as a matter of fact, only the central portion was yet
+blazing. But it was only a question of time when the remainder would
+ignite.
+
+And it was to this fact--that the fire was rushing up the stairway and
+elevator shafts as up a chimney--that Mary and her uncle, as well as
+Field and Melling, owed their temporary safety.
+
+Had Tom known that the girl he loved was in such direful danger, it is
+doubtful if his hand would have been as steady as it was on throttle
+and steering wheel. But not a muscle or nerve quivered. To Tom it was
+but carrying out a prearranged task. He was going to extinguish a great
+blaze, or attempt to do so, by means of his aerial fire-fighting
+apparatus. And his previous tests had given him confidence in his
+device. His one regret was that the fire department of the city that
+was contemplating the purchase of certain rights in his invention could
+not witness what he was about to do.
+
+"But they'll hear of it," declared Ned, when Tom voiced this idea to
+his chum.
+
+Nearer and nearer to the up-spouting column of flames the airship
+winged her way. Tense and alert, Tom sat at the wheel guiding his craft
+with her load of fire-defying chemicals. Behind him were Ned, Mr. Damon
+and Mr. Baxter, ready to drop the grenades at the word.
+
+"Getting close, Tom!" called Ned, as they could all feel the heat of
+the conflagration in the Landmark Building, which now seemed doomed.
+
+"You'll not dare cross it too low down, will you?"
+
+"No, I'll have to keep pretty well up," was the answer. "There's a
+current of air over that fire which might turn us turtle."
+
+Heat creates a draft, sucking in colder air from below, and making an
+upward-rushing column which, in the case of a big blaze, is very
+powerful. Tom knew he had to avoid this.
+
+It was now almost time to act. In another few seconds they would be
+sailing directly into the path of the up-spouting flames. Realizing
+that to do this at too low an elevation would result in disaster, Tom
+sent his craft upward at a sharp angle. Then he turned to call to his
+companions.
+
+"Be ready when I give the word!"
+
+"All set and ready!" answered Ned, and the others signified their
+attention to the command that soon was to be given.
+
+Having attained what he considered a sufficient elevation, Tom headed
+the Lucifer straight toward the up-spouting column of fire and smoke.
+If ever his craft of the air was to justify her name it was now!
+
+Straight and true as an arrow she headed for the fiery pillar! Hotter
+and hotter grew the air! The darkness of the night was lighted by the
+awful fire, which rendered objects in the street clear and distinct.
+But Tom and his friends had little time for such observation.
+
+"Get ready!" cried the young inventor, as he felt a rush of heat across
+his face, partly protected, as it was, by great goggles.
+
+"All ready!" shouted Ned.
+
+"Let go!" cried Tom, and with a click of springs the fire extinguishers
+dropped from the bottom of the Lucifer into the very heart of the
+flames in the Landmark Building.
+
+There was a blast as from a furnace seventy times heated, a choking and
+gasping for breath on the part of the occupants of the airship, a
+shriveling, as it seemed, of the naked flesh, and then, when it
+appeared that all of them must be engulfed in the great heat, the
+airship passed out of the zone of fire.
+
+A rush of cool air followed, reviving them all, and then, when out of
+the swirls of smoke, Ned, looking back, cried:
+
+"Good work, Tom! Good work!"
+
+"Did we hit it?" cried the young inventor. "She's half gone!" declared
+Mr. Baxter. "Can you give her the rest of the load?"
+
+"I'm going to try!" declared Tom.
+
+"Bless my bank balance!" shouted Mr. Damon, "are we going through that
+awful furnace again?"
+
+"It will not be so bad this time," observed Ned. "The fire is half out
+now. Tom's stuff did the trick!"
+
+Indeed it was evident, as Tom sent the Lucifer around in a sharp turn,
+that the fire had been largely smothered by the gas that now lay over
+it like a wet blanket. But there was still some fire spouting up.
+
+"Give her all we have!" yelled Tom, as, once more, he prepared to cross
+the zone of fire.
+
+"Right," sang out Ned.
+
+Once more the Lucifer swept over the burning building. Down shot the
+remaining grenades, falling into the mass of flames and bursting,
+though the reports could not be heard because of the tumult in the
+streets below. For the firemen and spectators had seen the sudden dying
+down of the fire, they had caught sight of a shadowy shape in the
+night, hovering over the blazing building, and they wondered what it
+all meant.
+
+"How is it?" asked Tom, as he guided the craft back to get a view of
+his work.
+
+"That settles it!" answered Ned. "There isn't fire enough now to broil
+a beefsteak!"
+
+This was not exactly true, for the blaze was not entirely subdued. But
+the flames had all been killed off in the higher parts of the Landmark
+Building, and what remained could easily be dealt with by the firemen
+on the ground. They proceeded to make short work of the remainder of
+the conflagration, the while wondering who had so effectively aided
+them from the clouds.
+
+"Well," observed Tom, as he saw how effectively he had smothered the
+great fire, "it's of no use to go on now. I haven't an ounce of
+chemical left on board. I can't give the demonstration that I planned
+for tomorrow."
+
+"You've given a better demonstration here than you ever could have in
+the other city," declared Mr. Baxter. "I fancy this will be all the
+test needed, Tom Swift!"
+
+"Perhaps. I hope so. But we may as well land and see from the ground
+the effect of our work. I'd also like to inquire if any one was hurt.
+Let's go down."
+
+It was rather ticklish work, making a landing in the midst of a
+populous city, and at night. But as it happened, there had been a
+number of buildings razed in the vicinity of the Landmark structure,
+and there was a large, vacant level space. Also several of the city's
+fire department searchlights were focused around the burning structure,
+and when it became evident that an airship was going to land--though as
+yet none guessed whose it was--the searchlights were turned on the
+vacant spot and Tom was able to make a good landing, his own powerful
+searchlight giving effective aid.
+
+"What did you do that put out the fire?" demanded the chief of the
+Newmarket department, as he rushed up with a crowd of others when Tom
+and his friends alighted.
+
+"I dropped a few grenades down that chimney," modestly answered the
+young inventor.
+
+"A few grenades! Say, you must have turned a whole river of them
+loose!" cried the delighted chief. "It doused the fire quicker than I
+ever saw one put out in all my life!"
+
+"I'm glad I was successful," said Tom. "But was any one in the
+building?"
+
+"Yes, a few," answered a policeman, who was trying to keep the crowd
+back from the airship. "They're bringing them out now."
+
+"Killed?" gasped Tom.
+
+"No. But some of them are badly hurt," the officer answered. "There
+was one young lady and a man named Barton Keith--"
+
+"Barton Keith!" shouted Tom, springing forward. "Was he--Who was the
+young lady? I--I--"
+
+But at that moment there was a stir in the crowd about the building, in
+which only a little fire flow remained, and through the throng came a
+disheveled and smoke-blackened young lady and a man whose clothing was
+also greatly disarrayed.
+
+"Mary!" cried the young inventor.
+
+"Tom!" gasped Mary Nestor. "How did you get here?"
+
+"I came to put out the fire," was the answer, and Tom cooled down now
+that he saw Mary was unharmed. "How did you happen to be in the
+building?"
+
+"I was in Uncle Barton's office when the fire broke out," answered
+Mary, "and we were trapped. We had to stay there, with two men from the
+floor above."
+
+"Yes, and if they had stayed with us they wouldn't have been hurt,"
+said Mr. Keith. "But, as it was, they rushed out and tried to get down
+the stairs. They were caught in the draft and badly burned, I believe.
+They are bringing them out now."
+
+Two stretchers, on which lay inert forms, were borne through the now
+silent crowd by firemen and police officers, and taken to waiting
+ambulances.
+
+"That's Field and Melling," said Mr. Keith to Tom. "They had offices
+just above me, and they were trapped, as were Mary and I. They acted
+like big cowards, too, though I hope they're not badly hurt. We stayed
+inside my office, and we were just giving up the hope of rescue when
+the fire seemed suddenly to die down."
+
+"I should say it was sudden!" cried the enthusiastic local chief. "It
+was the chemicals from this young man's airship that did the trick!"
+
+"Oh, Tom, was it your new machine?" asked Mary.
+
+"Yes," was the answer. "I was on my way to give a test tomorrow in
+Denton when I saw this fire. I didn't know you were in it, though,
+Mary."
+
+"Oh, but I'm glad you came," she said. "It was just--awful!" and she
+clung to Tom's arm, trembling.
+
+When Field and Melling, whose rash conduct had caused them to be
+severely but not fatally burned, had been taken to a hospital and the
+fire was declared to be practically out, Tom made arrangements to leave
+his airship in the city field all night.
+
+"And you and your friends can come to Uncle Jasper's house," said Mary.
+
+"Of course!" said Uncle Jasper himself, who had arrived on the scene,
+attracted to the fire by the news that his niece and Mr. Keith were in
+danger. "Lots of room! Come along! We'll celebrate your rescue."
+
+So the crew of the fire-fighting Lucifer went with Mary, while the
+firemen, after again thanking Tom most enthusiastically, kept on
+playing, as a precaution, their streams of water on the still hot
+building.
+
+Only the central portion of the structure, the stairs and elevator
+shafts, were burned away. The strong upward draft had kept the fire
+from spreading much to either side.
+
+"It certainly was a fierce blaze, and I'm glad my chemicals took such
+prompt effect," said Tom. "I shall not fear any test after this."
+
+It was the day following the night of excitement, and Tom and his
+friends, at the invitation of the fire department of Newmarket, were
+inspecting what was left of the Landmark Building--and there was
+considerable left--though access to the upper floors was to be had only
+by ladders, down which Mary and her uncle, Barton Keith, had been
+carried.
+
+"Here are my offices," said Mr. Keith, who accompanied Tom, Ned, Mr.
+Damon and Mr. Baxter, as he ushered them into his suite of rooms.
+
+"Bless my fountain pen! nothing is burned here," cried the eccentric
+man.
+
+"No, the flames just shot upward," explained the fire chief, who was
+leading the party. "But I think those chemicals of yours would have
+been just as effective, Mr. Swift, if the fire had mushroomed out more."
+
+"It was hot enough as it was," answered Tom, with a grim laugh.
+
+"Bless my thermometer, too hot--too hot by far!" exclaimed Tom Swift's
+eccentric friend, and to this Ned nodded an amused agreement.
+
+An exclamation from Mr. Baxter attracted the attention of all in Mr.
+Keith's office. The chemist picked up from the floor a bundle of papers.
+
+"Here is a bundle of documents that some one has dropped, Mr. Keith,"
+he said. "I guess you forgot to put it in your safe. Why--why--no--they
+aren't yours! They're mine. Here are my missing dye formulae! The secret
+papers I've been searching for so long! The ones I thought Field and
+Melling had!" cried Mr. Baxter. "How--how did they get here?" and,
+wonderingly, he looked at the bundle of papers he had discovered in such
+a strange manner.
+
+
+
+
+CHAPTER XXV
+
+THE LIGHT OF DAY
+
+
+"What's that? Your dye formulae here in my office?" cried Mr. Keith,
+for he had heard something of the chemist's loss, though he did not
+directly associate Field and Melling with it.
+
+"That's what this is! The very papers, containing all the rare secrets,
+for which I have been so at a loss!" cried the delighted old man. "Now
+I can give to the world the dyes for which it has long been waiting!
+Oh, Tom Swift, you did more than you knew when you put out this fire!"
+and he hugged the bundle of smoke-smelling papers to his breast.
+
+"But how did they get here?" asked the young inventor. "I know that
+Field and Melling had offices in this building. They were starting a
+new dye concern, and, though Mr. Baxter and I suspected them of having
+stolen his secret, we couldn't prove it."
+
+"But we can now!" cried Mr. Baxter. "Though I don't know that I'll
+bother even to accuse them, as long as I have back my previous papers.
+I see how it happened. They had the formulae in their office. They
+rushed out with the documents, and, when they found they couldn't get
+past this floor, they went into Mr. Keith's office. There, in their
+excitement, they dropped the papers, and you put the fire out just in
+time, Tom, or they'd have been burned beyond hope of saving. You have
+given me back something almost as valuable as life, Tom Swift!"
+
+"I'm glad I could render you that service," said the young inventor.
+"And I had no idea, when I dropped the chemicals, that I was saving
+someone even more valuable than your secret formulae," and they all
+knew he referred to Mary Nestor.
+
+An examination of the papers found on Mr. Keith's office floor showed
+that not one of the dye secrets was missing. Thus Mr. Baxter came into
+possession of his own again, and when Field and Melling were
+sufficiently recovered they were charged with the theft of the papers.
+The charge was proved, and, in addition, other accusations were brought
+against them which insured their remainder in jail for a considerable
+period.
+
+As Mr. Baxter had suspected, Field and Melling had, indeed, robbed him
+of his dye formulae papers. They learned that he possessed them, and
+they invited him to a night conference with the purpose of robbing him.
+The fire in their factory was an accident, of which they took advantage
+to make it appear that the chemist lost his papers in the blaze. But
+they had taken them, and though they did not mean to leave poor Baxter
+to his fate, that would have been the result of their selfish action
+had not Tom and Ned come to the rescue. And it was of this "putting
+over" that Field and Melling had boasted, the time Tom overheard their
+talk at Meadow Inn.
+
+As Mr. Baxter guessed, the letter delivered to him at Tom's place was
+one that the two scoundrels would have retained, as they had others
+like it, if they had seen it. But a new clerk forwarded it, and the
+evidence it contained helped to convict Field and Melling.
+
+As for the Landmark Building, while badly damaged, it would have been
+worse burned but for Tom's prompt action. And though he was more than
+glad that he had been on hand, he rather regretted that he could not
+give the test for which he had set out.
+
+Eventually the building was made more nearly fire-proof and the
+fire-escapes were rebuilt, and Mr. Blake did not lose his money, as he
+had feared, though Barton Keith said it was more owing to Tom Swift's
+good luck than to Mr. Blake's management.
+
+But, as it developed, nothing could have been more opportune than Tom's
+action, for word of his quenching a bigger blaze than he would have had
+to encounter in the official test reached the Denton fire department.
+As a result there was a conference, and, after only a nominal showing
+of his apparatus, it was adopted by a unanimous vote.
+
+But this occurred some time afterward, for, following his rescue of
+Mary Nestor and her uncle and the saving of the lives of Field and
+Melling, as well as others in the building, by his prompt smothering of
+the fire, Tom returned to Shopton.
+
+He and his companions went in the Lucifer, minus, now, the big load of
+chemicals, and on landing near the hangar Tom was surprised to see Koku
+the giant running toward him. The big man showed every symptom of great
+excitement as he cried:
+
+"Oh, Master Tom! He see the light ob day! he see the light ob day now!
+Oh, so glad! So glad!"
+
+"Who sees the light of day?" asked the young inventor.
+
+"Black Rad! Eradicate! Him eyes all better now! Pill man take off
+cloth. Rad--he see light ob day!"
+
+"Oh, I'm so glad! So thankful!" cried Tom. "How I've wished for this!
+Is it really true, Koku?"
+
+"Sure true! Pill man say Rad see K O now." The giant, doubtless, meant
+"O K," but Tom understood. And it was true, as he learned more directly
+a little later.
+
+When Tom entered the room where Rad had been kept in the dark ever
+since the explosion, the colored man looked at his master with seeing
+eyes, though the apartment was still but dimly lighted.
+
+"I's all right ag'in now, Massa Tom!" cried Rad. "See fine! I's all
+ready to make more smellin' stuff to put out fires!"
+
+"You won't have to, Rad!" cried Tom joyfully. "My chemical extinguisher
+is completed, and you did your share in making it a success. But I
+never would have felt like claiming credit for it if you had been--had
+been left in the dark."
+
+"No mo' dark, Massa Tom!" said Eradicate. "I kin see now as good as
+eber, an' yo'-all won't hab to 'pend on dat lazy good-fo'-nuffin
+cocoanut!" and he chuckled as he looked at the giant.
+
+"Huh! Lazy!" retorted the big man. "I show you--black coon!"
+
+"By golly!" laughed Rad. "Him an' me good friends now, Massa Tom. Neber
+I fuss wif Koku any mo'! He suah was good to me when I had to stay in
+de dark!"
+
+Of course it would be too much to hope that Koku and Eradicate never
+again quarreled, but for a long time their warm friendship was a thing
+at which to marvel, considering the past.
+
+"Well, I guess this settles it," said Tom to Ned one day, after going
+over the day's mail.
+
+"Settles what, Tom?"
+
+"My aerial fire-fighting apparatus. Here's word from the National Fire
+Underwriters Association that they have adopted it, and there will be a
+big reduction of rates in all cities where it is a part of the fire
+department equipment. It's been as great a success as Mr. Baxter's new
+dye."
+
+"Yes, and he has had wonderful success with that. But what are you
+going to do now, Tom? What new line of endeavor are you going to aim
+at?"
+
+Tom arose and reached for his hat.
+
+"I am now going," he said, with a grin, "to see somebody on private
+business."
+
+"You are going to see Mary Nestor!" broke out Ned.
+
+"I am," said Tom.
+
+And he did.

+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by

+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
+and the Foundation web page at https://www.pglaf.org.

+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.
