+CHAPTER I
+
+A MOTOR-BOAT AUCTION
+
+
+"Where are you going, Tom?" asked Mr. Barton Swift of his son as the
+young man was slowly pushing his motor-cycle out of the yard toward the
+country road. "You look as though you had some object in view."
+
+"So I have, dad. I'm going over to Lanton."
+
+"To Lanton? What for?"
+
+"I want to have a look at that motor-boat."
+
+"Which boat is that, Tom? I don't recall your speaking about a boat
+over at Lanton. What do you want to look at it for?"
+
+"It's the motor-boat those fellows had who tried to get away with your
+turbine model invention, dad. The one they used at the old General
+Harkness mansion, in the woods near the lake, and the same boat that
+fellow used when he got away from me the day I was chasing him here."
+
+"Oh, yes, I remember now. But what is the boat doing over at Lanton?"
+
+"That's where it belongs. It's the property of Mr. Bently Hastings.
+The thieves stole it from him, and when they ran away from the old
+mansion, the time Mr. Damon and I raided the place, they left the boat
+on the lake. I turned it over to the county authorities, and they
+found out it belonged to Mr. Hastings. He has it back now, but I
+understand it's somewhat damaged, and he wants to get rid of it. He's
+going to sell it at auction to-day, and I thought I'd go over and take
+a look at it. You see--"
+
+"Yes, I see, Tom," exclaimed Mr. Swift with a laugh. "I see what
+you're aiming at. You want a motor-boat, and you're going all around
+Robin Hood's barn to get at it."
+
+"No, dad, I only--"
+
+"Oh, I know you, Tom, my lad!" interrupted the inventor, shaking his
+finger at his son, who seemed somewhat confused. "You have a nice
+rowing skiff and a sailboat, yet you are hankering for a motor-boat.
+Come now, own up. Aren't you?"
+
+"Well, dad, a motor-boat certainly would go fine on Lake Carlopa.
+There's plenty of room to speed her, and I wonder there aren't more of
+them. I was going to see what Mr. Hastings' boat would sell for, but I
+didn't exactly think of buying it' Still--"
+
+"But you wouldn't buy a damaged boat, would you?"
+
+"It isn't much damaged," and in his eagerness the young inventor (for
+Tom Swift had taken out several patents) stood his motor-cycle up
+against the fence and came closer to his father. "It's only slightly
+damaged," he went on. "I can easily fix it. I looked it all over
+before I gave it in charge of the authorities, and it's certainly a
+fine boat. It's worth nine hundred dollars--or it was when it was new."
+
+"That's a good deal of money for a boat," and Mr. Swift looked serious,
+for though he was well off, he was inclined to be conservative.
+
+"Oh, I shouldn't think of paying that much. In fact, dad, I really had
+no idea of bidding at the auction. I only thought I'd go over and get
+an idea of what the boat might sell for. Perhaps some day--"
+
+Tom paused. Since his father had begun to question him some new plans
+had come into the lad's head. He looked at his parent and saw a smile
+beginning to work around the corners of Mr. Swift's lips. There was
+also a humorous look in the eyes of the older inventor. He understood
+boys fairly well, even if he only had one, and he knew Tom perfectly.
+
+"Would you really like to make a bid on that boat Tom?" he asked.
+
+"Would I, dad? Well--" The youth did not finish, but his father knew
+what he meant.
+
+"I suppose a motor-boat would be a nice thing to have on Lake Carlopa,"
+went on Mr. Swift musingly. "You and I could take frequent trips in
+it. It isn't like a motor-cycle, only useful for one. What do you
+suppose the boat will go for, Tom?"
+
+"I hardly know. Not a high price, I believe, for motor-boats are so
+new on our lake that few persons will take a chance on them. But if
+Mr. Hastings is getting another, he will not be so particular about
+insisting on a high price for the old one. Then, too, the fact that it
+is damaged will help to keep the price down, though I know I can easily
+put it in good shape. I would like to make a bid, if you think it's
+all right."
+
+"Well, I guess you may, Tom, if you really want it. You have money of
+your own and a motor-boat is not a bad investment. What do you think
+ought to be the limit?"
+
+"Would you consider a hundred and fifty dollars too high?"
+
+Mr. Swift looked at Tom critically. He was plainly going over several
+matters in his mind, and not the least of them was the pluck his son
+had shown in getting back some valuable papers and a model from a gang
+of thieves. The lad certainly was entitled to some reward, and to
+allow him to get a boat might properly be part of it.
+
+"I think you could safely go as high as two hundred dollars, Tom," said
+Mr. Swift at length. "That would be my limit on a damaged boat for it
+might be better to pay a little more and get a new one. However, use
+your own judgment, but don't go over two hundred. So the thieves who
+made so much trouble for me stole that boat from Mr. Hastings, eh?"
+
+"Yes, and they didn't take much care of it either. They damaged the
+engine, but the hull is in good shape. I'm ever so glad you'll let me
+bid on it. I'll start right off. The auction is at ten o'clock and I
+haven't more than time to get there."
+
+"Now be careful how you bid. Don't raise your own figures, as I've
+sometimes seen women, and men too, do in their excitement. Somebody
+may go over your head; and if he does, let them. If you get the boat
+I'll be very glad on your account. But don't bring any of Anson
+Morse's gang back in it with you. I've seen enough of them."
+
+"I'll not dad!" cried Tom as he trundled his motor-cycle out of the
+gate and into the country road that led to the village of Shopton,
+where he lived, and to Lanton, where the auction was to be held. The
+young inventor had not gone far before he turned back, leaving his
+machine standing on the side path.
+
+"What's the matter?" asked his father, who had started toward one of
+several machine shops on the premises--shops where Mr. Swift and his
+son did inventive work.
+
+"Guess I'd better get a blank check and some money," replied Tom as he
+entered the house. "I'll need to pay a deposit if I secure the boat."
+
+"That's so. Well, good luck," and with his mind busy on a plan for a
+new kind of storage battery, the inventor went on to his workroom. Tom
+got some cash and his checkbook from a small safe he owned and was soon
+speeding over the road to Lanton, his motor-cycle making quite a cloud
+of dust. While he is thus hurrying along to the auction I will tell
+you something about him.
+
+Tom Swift, son of Barton Swift, lived with his father and a motherly
+housekeeper, Mrs. Baggert, in a large house on the outskirts of the
+town of Shopton, in New York State. Mr. Swift had acquired
+considerable wealth from his many inventions and patents, but he did
+not give up working out his ideas simply because he had plenty of
+money. Tom followed in the footsteps of his parent and had already
+taken out several patents.
+
+Shortly before this story opens the youth had become possessed of a
+motor-cycle in a peculiar fashion. As told in the first volume of this
+series, entitled "Tom Swift and His Motor-cycle," Tom was riding to the
+town of Mansburg on an errand for his father one day when he was nearly
+run down by a motorcyclist. A little later the same motorcyclist, who
+was a Mr. Wakefield Damon, of Waterfield, collided with a tree near
+Tom's home and was severely cut and bruised, the machine being broken.
+Tom and his father cared for the injured rider, and Mr. Damon, who was
+an eccentric individual, was so disheartened by his attempts to ride
+the motor-cycle that he sold it to Tom for fifty dollars, though it had
+cost much more.
+
+About the same time that Tom bought the motor-cycle a firm of rascally
+lawyers, Smeak & Katch by name, had, in conjunction with several men,
+made an attempt to get control of an invention of a turbine motor
+perfected by Mr. Swift. The men, who were Ferguson Appleson, Anson
+Morse, Wilson Featherton, alias Simpson, and Jake Burke, alias Happy
+Harry, who sometimes disguised himself as a tramp, tried several times
+to steal the model.
+
+Their anxiety to get it was due to the fact that they had invested a
+large sum in a turbine motor invented by another man, but their motor
+would not work and they sought to steal Mr. Swift's. Tom was sent to
+Albany on his motor-cycle to deliver the model and some valuable papers
+to Mr. Crawford, of the law firm of Reid & Crawford, of Washington,
+attorneys for Mr. Swift. Mr. Crawford had an errand in Albany and had
+agreed to meet Tom there with the model.
+
+But, on the way, Tom was attacked by the gang of unscrupulous men and
+the model was stolen. He was assaulted and carried far away in an
+automobile. In an attempt to capture the gang in a deserted mansion,
+in the woods on the shore of Lake Carlopa, Tom was aided by Mr. Damon,
+of whom he had purchased the motor-cycle. The men escaped, however,
+and nothing could be done to punish them.
+
+Tom was thinking of the exciting scenes he had passed through about a
+month previous as he spun along the road leading to Lanton.
+
+"I hope I don't meet Happy Harry or any of his gang to-day," mused the
+lad as he turned on a little more power to enable his machine to mount
+a hill. "I don't believe they'll attend the auction, though. It would
+be too risky for them."
+
+As Tom swung along at a rapid pace he heard, behind him, the puffing of
+an automobile, with the muffler cut out. He turned and cast a hasty
+glance behind.
+
+"I hope that ain't Andy Foger or any of his cronies," he said to
+himself. "He might try to run me down just for spite. He generally
+rushes along with the muffler open so as to attract attention and make
+folks think he has a racing car."
+
+It was not Andy, however, as Tom saw a little later, as a man passed
+him in a big touring car. Andy Foger, as my readers will recollect,
+was a red-haired, squinty-eyed lad with plenty of money and not much
+else. He and his cronies, including Sam Snedecker, nearly ran Tom down
+one day, when the latter was on his bicycle, as told in the first
+volume of this series. Andy had been off on a tour with his chums
+during the time when Tom was having such strenuous adventures and had
+recently returned.
+
+"If I can only get that boat," mused Tom as he swung back into the
+middle of the road after the auto had passed him, "I certainly will
+have lots of fun. I'll make a week's tour of Lake Carlopa and take dad
+and Ned Newton with me." Ned was Tom's most particular chum, but as
+young Newton was employed in the Shopton bank, the lad did not have
+much time for pleasure. Lake Carlopa was a large body of water, and it
+would take a moderately powered boat several days to make a complete
+circuit of the shore, so cut up into bays and inlets was it.
+
+In about an hour Tom was at Lanton, and as he neared the home of Mr.
+Hastings, which was on the shore of the lake, he saw quite a throng
+going down toward the boathouse.
+
+"There'll be some lively bidding," thought Tom as he got off his
+machine and pushed it ahead of him through the drive and down toward
+the river. "I hope they don't go above two hundred dollars, though."
+
+"Get out the way there!" called a sudden voice, and looking back, Tom
+saw that an automobile had crept up silently behind him. In it were
+Andy Foger and Sam Snedecker. "Why don't you get out the way?"
+petulantly demanded the red-haired lad.
+
+"Because I don't choose to," replied Tom calmly, knowing that Andy
+would never dare to speed up his machine on the slope leading down to
+the lake.
+
+"Go ahead, bump him!" the young inventor heard Sam whisper.
+
+"You'd better try it, if you want to get the best trouncing you ever
+had!" cried Tom hotly.
+
+"Hu! I s'pose you think you're going to bid on the boat?" sneered Andy.
+
+"Is there any law against it?" asked Tom.
+
+"Hu! Well, you'll not get it. I'm going to take that boat," retorted
+the squint-eyed bully. "Dad gave me the money to get it."
+
+"All right," answered Tom non-committally. "Go ahead. It's a free
+country."
+
+He stood his motor-cycle up against a tree and went toward a group of
+persons who were surrounding the auctioneer. The time had arrived to
+start the sale. As Tom edged in closer he brushed against a man who
+looked at him sharply. The lad was just wondering if he had ever seen
+the individual before, as there seemed to be something strangely
+familiar about him, when the man turned quickly away, as if afraid of
+being recognized.
+
+"That's odd," thought Tom, but he had no further time for speculation,
+as the auctioneer was mounting on a soapbox and had begun to address
+the gathering.
+
+
+
+
+CHAPTER II
+
+SOME LIVELY BIDDING
+
+
+"Attention, people!" cried the auctioneer. "Give me your attention for
+a few minutes, and we will proceed with the business in hand. As you
+all know, I am about to dispose of a fine motor-boat, the property of
+Mr. Bently Hastings. The reason for disposing of it at auction is
+known to most of you, but for the benefit of those who do not, I will
+briefly state them. The boat was stolen by a gang of thieves and
+recovered recently through the efforts of a young man, Thomas Swift,
+son of Barton Swift, our fellow-townsman, of Shopton." At that moment
+the auctioneer, Jacob Wood, caught sight of Tom in the press, and,
+looking directly at the lad, continued:
+
+"I understand that young Mr. Swift is here to-day, and I hope he
+intends to bid on this boat. If he does, the bidding will be lively,
+for Tom Swift is a lively young man. I wish I could say that some of
+the men who stole the boat were here to-day."
+
+The auctioneer paused and there were some murmurs from those in the
+throng as to why such a wish should be uttered. Tom felt some one
+moving near him, and, looking around, he saw the same man with whom he
+had come in contact before. The person seemed desirous of getting out
+on the edge of the crowd, and Tom felt a return of his vague
+suspicions. He looked closely at the fellow, but could trace no
+resemblance to any of the men who had so daringly stolen his father's
+model.
+
+"The reason I wish they were here to-day," went on Mr. Wood, "is that
+the men did some slight damage to the boat, and if they were here
+to-day we would make them pay for it. However, the damage is slight
+and can easily be repaired. I mention that, as Mr. Hastings desired me
+to. Now we will proceed with the bidding, and I will say that an
+opportunity will first be given all to examine the boat. Perhaps Tom
+Swift will give us his opinion on the state it is in as we know he is
+well qualified to talk about machinery."
+
+All eyes were turned on Tom, for many knew him.
+
+"Humph! I guess I know as much about boats and motors as he does,"
+sneered Andy Foger. "He isn't the only one in this crowd! Why didn't
+the auctioneer ask me?"
+
+"Keep quiet," begged Sam Snedecker. "People are laughing at you, Andy."
+
+"I don't care if they are," muttered the sandy haired youth. "Tom
+Swift needn't think he's everything."
+
+"If you will come down to the dock," went on the auctioneer, "you can
+all see the boat, and I would be glad to have young Mr. Swift give us
+the benefit of his advice."
+
+The throng trooped down to the lake, and, blushing somewhat, Tom told
+what was the matter with the motor and how it could be fixed. It was
+noticed that there was less enthusiasm over the matter than there had
+been, for certainly the engine, rusty and out of order as it was, did
+not present an attractive sight. Tom noted that the man, who had acted
+so strangely, did not come down to the dock.
+
+"Guess he can't be much interested in the motor," decided Tom.
+
+"Now then, if it's all the same to you folks, I'll proceed with the
+auction here," went on Mr. Wood. "You can all see the boat from here.
+It is, as you see, a regular family launch and will carry twelve
+persons comfortably. With a canopy fitted to it a person could cruise
+all about the lake and stay out over night, for you could sleep on the
+seat cushions. It is twenty-one feet in length and has a
+five-and-a-half-foot beam, the design being what is known as a
+compromise stern. The motor is a double-cylinder two-cycle one, of ten
+horsepower. It has a float-feed carburetor, mechanical oiler, and the
+ignition system is the jump-spark--the best for this style of motor.
+The boat will make ten miles an hour, with twelve in, and, of course,
+more than that with a lighter load. A good deal will depend on the way
+the motor is managed.
+
+"Now, as you know, Mr. Hastings wishes to dispose of the boat partly
+because he does not wish to repair it and partly because he has a newer
+and larger one. The craft, which is named CARLOPA by the way, cost
+originally nine hundred dollars. It could not be purchased new to-day,
+in many places, for a thousand. Now what am I offered in its present
+condition? Will any one make an offer? Will you give me five hundred
+dollars?"
+
+The auctioneer paused and looked critically at the throng. Several
+persons smiled. Tom looked worried. He had no idea that the price
+would start so high.
+
+"Well, perhaps that is a bit stiff," went on Mr. Wood. "Shall we say
+four hundred dollars? Come now, I'm sure it's worth four hundred.
+Who'll start it at four hundred?"
+
+No one would, and the auctioneer descended to three hundred, then to
+two and finally, as if impatient, he called out:
+
+"Well, will any one start at fifty dollars?"
+
+Instantly there were several cries of "I will!"
+
+"I thought you would," went on the auctioneer. "Now we will get down
+to work. I'm offered fifty dollars for this twenty-one foot, ten
+horsepower family launch. Will any one make it sixty?"
+
+"Sixty!" called out Andy Foger in a shrill voice. Several turned to
+look at him.
+
+"I didn't know he was going to bid," thought Tom. "He may go above me.
+He's got plenty of money, and, while I have too, I'm not going to pay
+too much for a damaged boat."
+
+"Sixty I'm bid, sixty--sixty!" cried Mr. Wood in a sing-song tone,
+"who'll make it seventy?"
+
+"Sixty-five!" spoke a quiet voice at Tom's elbow, and he turned to see
+the mysterious man who had joined the crowd at the edge of the lake.
+
+"Sixty-five from the gentleman in the white straw hat!" called Mr. Wood
+with a smile at his wit, for there were many men wearing white straw
+hats, the day being a warm one in June.
+
+"Here, who's bidding above me?" exclaimed Andy, as if it was against
+the law.
+
+"I guess you'll find a number going ahead of you, my young friend,"
+remarked the auctioneer. "Will you have the goodness not to interrupt
+me, except when you want to bid?"
+
+"Well, I offered sixty," said the squint-eyed bully, while his crony,
+Sam Snedecker, was vainly, pulling at his sleeve.
+
+"I know you did, and this gentleman went above you. If you want to bid
+more you can do so. I'm offered sixty-five, sixty-five I'm offered for
+this boat. Will any one make it seventy-five?"
+
+Mr. Wood looked at Tom, and our hero, thinking it was time for him to
+make a bid, offered seventy. "Seventy from Tom Swift!" cried the
+auctioneer. "There is a lad who knows a motor-boat from stem to stern,
+if those are the right words. I don't know much about boats except what
+I'm told, but Tom Swift does. Now, if he bids, you people ought to know
+that it's all right. I'm bid seventy--seventy I'm bid. Will any one
+make it eighty?"
+
+"Eighty!" exclaimed Andy Foger after a whispered conference with Sam.
+"I know as much about boats as Tom Swift. I'll make it eighty."
+
+"No side remarks. I'll do most of the talking. You just bid, young
+man," remarked Mr. Wood. "I have eighty bid for this boat--eighty
+dollars. Why, my friends, I can't understand this. I ought to have it
+up to three hundred dollars, at least. But I thank you all the same. We
+are coming on. I'm bid eighty--"
+
+"Ninety!" exclaimed the quiet man at Tom's elbow. He was continually
+fingering his upper lip, as though he had a mustache there, but his
+face was clean-shaven. He looked around nervously as he spoke.
+
+"Ninety!" called out the auctioneer.
+
+"Ninety-five!" returned Tom. Andy Foger scowled at him, but the young
+inventor only smiled. It was evident that the bully did not relish
+being bid against. He and his crony whispered together again.
+
+"One hundred!" called Andy, as if no one would dare go above that.
+
+"I'm offered an even hundred," resumed Mr. Wood. "We are certainly
+coming on. A hundred I am bid, a hundred--a hundred--a hundred--"
+
+"And five," said the strange man hastily, and he seemed to choke as he
+uttered the words.
+
+"Oh, come now; we ought to have at least ten-dollar bids from now on,"
+suggested Mr. Wood. "Won't you make it a hundred and ten?" The
+auctioneer looked directly at the man, who seemed to shrink back into
+the crowd. He shook his head, cast a sort of despairing look at the
+boat and hurried away.
+
+"That's queer," murmured Tom. "I guess that was his limit, yet if he
+wanted the boat badly that wasn't a high price."
+
+"Who's going ahead of me?" demanded Andy in loud tones.
+
+"Keep quiet!" urged Sam. "We may get it yet."
+
+"Yes, don't make so many remarks," counseled the auctioneer. "I'm bid
+a hundred and five. Will any one make it a hundred and twenty-five?"
+
+Tom wondered why the man had not remained to see if his bid was
+accepted, for no one raised it at once, but he hurried off and did not
+look back. Tom took a sudden resolve.
+
+"A hundred and twenty-five!" he called out.
+
+"That's what I like to hear," exclaimed Mr. Wood. "Now we are doing
+business. A hundred and twenty-five from Tom Swift. Will any one
+offer me fifty?"
+
+Andy and Sam seemed to be having some dispute.
+
+"Let's make him quit right now," suggested Andy in a hoarse whisper.
+
+"You can't," declared Sam'
+
+"Yes, I can. I'll go up to my limit right now."
+
+"And some one will go above you---maybe Tom will," was Sam's retort.
+
+"I don't believe he can afford to," Andy came back with. "I'm going to
+call his bluffs. I believe he's only bidding to make others think he
+wants it. I don't believe he'll buy it."
+
+Tom heard what was said, but did not reply. The auctioneer was calling
+monotonously: "I'm bid a hundred and twenty-five--twenty-five. Will
+any one make it fifty?"
+
+"A hundred and fifty!" sang out Andy, and all eyes were directed toward
+him.
+
+"Sixty!" said Tom quietly.
+
+"Here, you--" began the red-haired lad. "You--"
+
+"That will do!" exclaimed the auctioneer sternly. "I am offered a
+hundred and sixty. Now who will give me an advance? I want to get the
+boat up to two hundred, and then the real bidding will begin."
+
+Tom's heart sank. He hoped it would be some time before a two hundred
+dollar offer would be heard. As for Andy Foger, he was almost
+speechless with rage. He shook off the restraining arm of Sam, and,
+worming his way to the front of the throng, exclaimed:
+
+"I'll give a hundred and seventy-five dollars for that boat!"
+
+"Good!" cried the auctioneer. "That's the way to talk. I'm offered a
+hundred and seventy-five."
+
+"Eighty," said Tom quietly, though his heart was beating fast.
+
+"Well, of all--" began Andy, but Sam Snedecker dragged him back.
+
+"You haven't got any more money," said the bully's crony. "Better stop
+now."
+
+"I will not! I'm going home for more," declared Andy. "I must have
+that boat."
+
+"It will be sold when you get back," said Sam.
+
+"Haven't you got any money you can lend me?" inquired the squint-eyed
+one, scowling in Tom's direction. "No, not a bit. There, some one
+raised Tom's bid."
+
+At that moment a man in the crowd offered a hundred and eighty-one
+dollars.
+
+"Small amounts thankfully received," said Mr. Wood with a laugh. Then
+the bidding became lively, a number making one-dollar advances.
+
+The price got up to one hundred and ninety-five dollars and there it
+hung for several minutes, despite the eloquence of Mr. Wood, who tried
+by all his persuasive powers to get a substantial advance. But every
+one seemed afraid to bid. As for the young inventor, he was in a
+quandary. He could only offer five dollars more, and, if he bid it in
+a lump, some one might go to two hundred and five, and he would not get
+the boat. He wished he had secured permission from his father to go
+higher, yet he knew that as a fair proposition two hundred dollars was
+about all the motor-boat in its present condition was worth, at least
+to him. Then he made a sudden resolve. He thought he might as well
+have the suspense over.
+
+"Two hundred dollars!" he called boldly.
+
+"I'm offered two hundred!" repeated Mr. Wood. "That is something like
+it. Now who will raise that?"
+
+There was a moment of silence. Then the auctioneer swung into an
+enthusiastic description of the boat. He begged for an advance, but
+none was made, though Tom's heart seemed in his throat, so afraid was
+he that he would not get the CARLOPA.
+
+"Two hundred--two hundred!" droned on Mr. Wood. "I am offered two
+hundred. Will any of you go any higher?" He paused a moment, and Tom's
+heart beat harder than ever. "If not," resumed the speaker, "I will
+declare the bidding closed. Are you all done? Once--twice--three
+times. Two hundred dollars. Going--going--gone!" He clapped his hands.
+"The boat is sold to Thomas Swift for two hundred dollars. If he'll
+step up I'll take his money."
+
+There was a laugh as Tom, blushingly, advanced. He passed Andy Foger,
+who had worked his way over near him.
+
+"You got the boat," sneered the bully, "and I s'pose you think you got
+ahead of me."
+
+"Keep quiet!" begged Sam.
+
+"I won't!" exclaimed Andy. "He outbid me just out of spite, and I'll
+get even with him. You see if I don't!"
+
+Tom looked Andy Foger straight in the eyes, but did not answer, and the
+red-haired youth turned aside, followed by his crony, and started
+toward his automobile.
+
+"I congratulate you on your bargain," said Mr. Wood as Tom proceeded to
+make out a check. He gave little thought to the threat Andy Foger had
+made, but the time was coming when he was to remember it well.
+
+
+
+
+CHAPTER III
+
+A TIMELY WARNING
+
+
+"Well, are you satisfied with your bargain, Tom?" asked Mr. Wood when
+the formalities about transferring the ownership of the motor-boat had
+been completed.
+
+"Oh, yes, I calculated to pay just what I did."
+
+"I'm glad you're satisfied, for Mr. Hastings told me to be sure the
+purchaser was satisfied. Here he comes now. I guess he wasn't at the
+auction."
+
+An elderly gentleman was approaching Mr. Wood and Tom. Most of the
+throng was dispersing, but the young inventor noticed that Andy Foger
+and Sam Snedecker stood to one side, regarding him closely.
+
+"So you got my boat," remarked the former owner of the craft. "I hope
+you will be able to fix it up."
+
+"Oh, I think I shall," answered the new owner of the CARLOPA. "If I
+can't, father will help me."
+
+"Yes, you have an advantage there. Are you going to keep the same
+name?" and Mr. Hastings seemed quite interested in what answer the lad
+would make.
+
+"I think not," replied Tom. "It's a good name, but I want something
+that tells more what a fast boat it is, for I'm going to make some
+changes that will increase the speed."
+
+"That's a good idea. Call it the Swift."
+
+"Folks would say I was stuck up if I did that," retorted the youth
+quickly. "I think I shall call it the ARROW. That's a good, short
+name, and--"
+
+"It's certainly speedy," interrupted Mr. Hastings. "Well now, since
+you're not going to use the name CARLOPA, would you mind if I took it
+for my new boat? I have a fancy for it."
+
+"Not in the least," said Tom. "Don't you want the letters from each
+side of the bow to put on your new craft?"
+
+"It's very kind of you to offer them, and, since you will have no need
+for them, I'll be glad to take them off."
+
+"Come down to my boat," invited Tom, using the word "my" with a proper
+pride, "and I'll take off the brass letters. I have a screw driver in
+my motor-cycle tool bag."
+
+As the former and present owners of the ARROW (which is the name by
+which I shall hereafter designate Tom's motor-boat) walked down toward
+the dock where it was moored the young inventor gave a startled cry.
+
+"What's the matter?" asked Mr. Hastings.
+
+"That man! See him at my motor-boat?" cried Tom. He pointed to the
+craft in the lake. A man was in the cockpit and seemed to be doing
+something to the forward bulkhead, which closed off the compartment
+holding the gasoline tank.
+
+"Who is he?" asked Mr. Hastings, while Tom started on a run toward the
+boat.
+
+"I don't know. Some man who bid on the boat at the auction, but who
+didn't go high enough," answered the lad. As he neared the craft the
+man sprang out, ran along the lakeshore for a short distance and then
+disappeared amid the bushes which bordered the estate of Mr. Hastings.
+Tom hurriedly entered the ARROW.
+
+"Did he do any damage?" asked Mr. Hastings.
+
+"I guess he didn't have time," responded Tom. "But he was tampering
+with the lock on the door of the forward compartment. What's in there?"
+
+"Nothing but the gasoline tank. I keep the bulkhead sliding door
+locked on general principles. I can't imagine what the fellow would
+want to open it for. There's nothing of value in there. Perhaps he
+isn't right in his head. Was he a tramp?"
+
+"No, he was well dressed but he seemed very nervous during the auction,
+as if he was disappointed not to have secured the boat. Yet what could
+he want in that compartment? Have you the key to the lock, Mr.
+Hastings?"
+
+"Yes, it belongs to you now, Mr. Swift," and the former owner handed it
+to Tom, who quickly unlocked the compartment. He slid back the door
+and peered within, but all he saw was the big galvanized tank.
+
+"Nothing in there he could want," commented the former owner of the
+craft.
+
+"No," agreed Tom in a low voice. "I don't see what he wanted to open
+the door for." But the time was to come, and not far off, when Tom was
+to discover quite a mystery connected with the forward compartment of
+his boat, and the solution of it was fated to bring him into no little
+danger.
+
+"It certainly is odd," went on Mr. Hastings when, after Tom had secured
+the screw driver from his motor-cycle tool bag, he aided the lad in
+removing the letters from the bow of the boat "Are you sure you don't
+know the man?"
+
+"No, I never saw him before. At first I thought his voice sounded like
+one of the members of the Happy Harry gang, but when I looked squarely
+at him I could not see a bit of resemblance. Besides, that gang would
+not venture again into this neighborhood."
+
+"No, I imagine not. Perhaps he was only a curious, meddlesome person.
+I have frequently been bothered by such individuals. They want to see
+all the working parts of an automobile or motor-boat, and they don't
+care what damage they do by investigating."
+
+Tom did not reply, but he was pretty certain that the man in question
+had more of an object than mere curiosity in tampering with the boat.
+However, he could discover no solution just then, and he proceeded with
+the work of taking off the letters.
+
+"What are you going to do with your boat, now that you have it?" asked
+Mr. Hastings. "Can you run it down to your dock in the condition in
+which it is now?"
+
+"No, I shall have to go back home, get some tools and fix up the motor.
+It will take half a day, at least. I will come back this afternoon
+and, have the boat at my house by night. That is if I may leave it at
+your dock here."
+
+"Certainly, as long as you like."
+
+The young inventor had many things to think about as he rode toward
+home, and though he was somewhat puzzled over the actions of the
+stranger, he forgot about that in anticipating the pleasure he would
+have when the motor-boat was in running order.
+
+"I'll take dad off on a cruise about the lake," he decided. "He needs
+a rest, for he's been working hard and worrying over the theft of the
+turbine motor model. I'll take Ned Newton for some rides, too, and he
+can bring his camera along and get a lot of pictures. Oh, I'll have
+some jolly sport this summer!"
+
+Tom was riding swiftly along a quiet country road and was approaching a
+steep hill, which he could not see until he was close to it, owing to a
+sharp turn.
+
+As he was about to swing around it and coast swiftly down the steep
+declivity he was startled by hearing a voice calling to him from the
+bushes at the side of the road.
+
+"Hold on, dar! hold on, Mistah Swift!" cried a colored man, suddenly
+popping into view. "Doan't go down dat hill."
+
+"Why, it's Eradicate Sampson!" exclaimed Tom, quickly shutting off the
+power and applying the brakes. "What's the matter, Rad? Why shouldn't
+I go down that hill?"
+
+"Beca'se, Mistah Swift, dere's a pow'ful monstrous tree trunk right
+across de road at a place whar yo' cain't see it till yo' gits right on
+top ob it. Ef yo' done hit dat ar tree on yo' lickity-split machine,
+yo' suah would land in kingdom come. Doan't go down dat hill!"
+
+Tom leaped off his machine and approached the colored man. Eradicate
+Sampson did odd jobs in the neighborhood of Shopton, and more than once
+Tom had done him favors in repairing his lawn mower or his wood-sawing
+machine. In turn Eradicate had given Tom a valuable clue as to the
+hiding place of the model thieves.
+
+"How'd the log get across the road, Rad?" asked Tom.
+
+"I dunno, Mistah Swift. I see it when I come along wid mah mule,
+Boomerang, an' I tried t' git it outer de way, but I couldn't. Den I
+left Boomerang an' mah wagon at de foot ob de hill an' I come up heah
+t' git a long pole t' pry de log outer de way. I didn't t'ink nobody
+would come along, case dis road ain't much trabeled."
+
+"I took it for a short cut," said the lad. "Come on, let's take a look
+at the log."
+
+Leaving his machine at the top of the slope, the young inventor
+accompanied the colored man 'down the hill. At the foot of it, well
+hidden from sight of any one who might come riding down, was a big log.
+It was all the way across the road.
+
+"That never fell there," exclaimed Tom in some excitement. "That never
+rolled off a load of logs, even if there had been one along, which
+there wasn't. That log was put there!"
+
+"Does yo' t'ink dat, Mistah Swift?" asked Eradicate, his eyes getting
+big.
+
+"I certainly do, and, if you hadn't warned me, I might have been
+killed."
+
+"Oh, I heard yo' lickity-split machine chug-chuggin' along when I were
+in de bushes, lookin' for a pryin' pole, an' I hurried out to warn yo.
+I knowed I could leave Boomerang safe, 'case he's asleep."
+
+"I'm glad you did warn me," went on the youth solemnly. Then, as he
+went closer to the log, he uttered an exclamation.
+
+"That has been dragged here by an automobile!" he cried. "It's been
+done on purpose to injure some one. Come on, Rad, let's see if we
+can't find out who did it."
+
+Something on the ground caught Tom's eye. He stooped and picked up a
+nickle-plated wrench.
+
+"This may come in handy as evidence," he murmured.
+
+
+
+
+CHAPTER IV
+
+TOM AND ANDY CLASH
+
+
+Even a casual observer could have told that an auto had had some part
+in dragging the log to the place where it blockaded the road. In the
+dust were many marks of the big rubber tires and even the imprint of a
+rope, which had been used to tow the tree trunk.
+
+"What fo' yo' t'ink any one put dat log dere?" asked the colored man as
+he followed Tom. Boomerang, the mule, so called because Eradicate said
+you never could tell what he was going to do, opened his eyes lazily
+and closed them again. "I don't know why, Rad, unless they wanted to
+wreck an automobile or a wagon. Maybe tramps did it for spite."
+
+"Maybe some one done it to make yo' hab trouble, Mistah Swift."
+
+"No, I hardly think so. I don't know of any one who would want to make
+trouble for me, and how would they know I was coming this way--"
+
+Tom suddenly checked himself. The memory of the scene at the auction
+came back to him and he recalled what Andy Foger had said about
+"'getting even."
+
+"Which way did dat auto go?" resumed Eradicate.
+
+"It came from down the road," answered Tom, not completing the sentence
+he had left unfinished. "They dragged the log up to the foot of the
+hill and left it. Then the auto went down this way." It was
+comparatively easy, for a lad of such sharp observation as was Tom, to
+trace the movements of the vehicle.
+
+"Den if it's down heah, maybe we cotch 'em," suggested the colored man.
+
+The young inventor did not answer at once. He was hurrying along, his
+eyes on the telltale marks. He had proceeded some distance from the
+place where the log was when he uttered a cry. At the same moment he
+hurried from the road toward a thick clump of bushes that were in the
+ditch alongside of the highway. Reaching them, he parted the leaves
+and called:
+
+"Here's the auto, Rad!"
+
+The colored man ran up, his eyes wider open than ever. There, hidden
+amid the bushes, was a large touring car.
+
+"Whose am dat?" asked Eradicate.
+
+Tom did not answer. He penetrated the underbrush, noting where the
+broken branches had been bent upright after the forced entrance of the
+car, the better to hide it. The young inventor was, seeking some clew
+to discover the owner of the machine. To this end he climbed up in the
+tonneau and was looking about when some one burst in through the screen
+of bushes and a voice cried: "Here, you get out of my car!"
+
+"Oh, is it your car, Andy Foger?" asked Tom calmly as he recognized his
+squint-eyed rival. "I was just beginning to think it was. Allow me to
+return your wrench," and he held out the one he had picked up near the
+log. "The next time you drag trees across the road," went on the lad
+in the tonneau, facing the angry and dismayed Andy, "I'd advise you to
+post a notice at the top of the hill, so persons riding down will not
+be injured."
+
+"Notice--road--hill--logs!" stammered Andy, turning red under his
+freckles.
+
+"That's what I said," replied Tom coolly.
+
+"I--I didn't have anything to do with putting a log across any road,"
+mumbled the bully. "I--I've been off toward the creek."
+
+"Have you?" asked Tom with a peculiar smile.
+
+"I thought you might have been looking for the wrench you dropped near
+the log. You should be more careful and so should Sam Snedecker, who's
+hiding outside the bushes," went on our hero, for he had caught sight
+of the form of Andy's crony. "I--I told him not to do it!" exclaimed
+Sam as he came from his hiding place.
+
+"Shut up!" exclaimed Andy desperately.
+
+"Oh, I think I know your secret," continued the young inventor. "You
+wanted to get even with me for outbidding you on the motor-boat. You
+watched which road I took, and then, in your auto, you came a shorter
+way, ahead of me. You hauled the log across the foot of the hill,
+hoping, I suppose, that my machine would be broken. But, let me tell
+you, it was a risky trick. Not only might I have been killed, but so
+would whoever else who happened to drive down the slope over the log,
+whether in a wagon or automobile. Fortunately Eradicate discovered it
+in time and warned me. I ought to have you arrested, but you're not
+worth it. A good thrashing is what such sneaks as you deserve!"
+
+"You haven't got any evidence against us," sneered Andy confidently,
+his old bravado coming back.
+
+"I have all I want," replied Tom. "You needn't worry. I'm not going
+to tell the police. But you've got to do one thing or I'll make you
+sorry you ever tried this trick. Eradicate will help me, so don't
+think you're going to escape."
+
+"You get out of my automobile!" demanded Andy. "I'll have you arrested
+if you don't."
+
+"I'll get out because I'm ready to, but not on account of your
+threats," retorted Mr. Swift's son. "Here's your wrench. Now I want
+you and Sam to start up this machine and haul that log out of the way."
+
+"S'pose I won't do it?" snapped Andy.
+
+"Then I'll cause your arrest, besides thrashing you into the bargain!
+You can take your choice of removing the log so travelers can pass or
+having a good hiding, you and Sam. Eradicate, you take Sam and I'll
+tackle Andy."
+
+"Don't you dare touch me!" cried the bully, but there was a whine in
+his tones.
+
+"You let me alone or I'll tell my father!" added Sam. "I--I didn't
+have nothin' to do with it, anyhow. I told Andy it would make trouble,
+but he made me help him."
+
+"Say, what's the matter with you?" demanded Andy indignantly of his
+crony. "Do you want to--"
+
+"I wish I'd never come with you," went on Sam, who was beginning to be
+frightened.
+
+"Come now. Start up that machine and haul the log out of the way,"
+demanded Tom again.
+
+"I won't do it!" retorted the red-haired lad impudently.
+
+"Yes, you will," insisted our hero, and he took a step toward the
+bully. They were out of the clump of bushes now and in the roadside
+ditch. "You let me alone," almost screamed Andy, and in his baffled
+rage he rushed at Tom, aiming a blow.
+
+The young inventor quickly stepped to one side, and, as the bully
+passed him, Tom sent out a neat left-hander. Andy Foger went down in a
+heap on the grass.
+
+
+
+
+CHAPTER V
+
+A TEST OF SPEED
+
+
+Whether Tom or Andy was the most surprised at the happening would be
+hard to say. The former had not meant to hit so hard and he certainly
+did not intend to knock the squint-eyed youth down. The latter's fall
+was due, as much as anything, to his senseless, rushing tactics and to
+the fact that he slipped on the green grass. The bully was up in a
+moment, however, but he knew better than to try conclusions with Tom
+again. Instead he stood out of reach and spluttered:
+
+"You just wait, Tom Swift! You just wait!"
+
+"Well, I'm waiting," responded the other calmly.
+
+"I'll get even with you," went on Andy. "You think you're smart
+because you got ahead of me, but I'll get square!"
+
+"Look here!" burst out the young inventor determinedly, taking a step
+toward his antagonist, at which Andy quickly retreated, "I don't want
+any more of that talk from you, Andy Foger. That's twice you've made
+threats against me to-day. You put that log across the road, and if
+you try anything like it for your second attempt I'll make you wish you
+hadn't. That applies to you, too, Sam," he added, glancing at the
+other lad.
+
+"I--I ain't gone' to do nothin'," declared Sam.
+
+"I told Andy not to put that tree--"
+
+"Keep still, can't you!" shouted the bully. "Come on. We'll get even
+with him, that's all," he muttered as he went back into the bushes
+where the auto was. Andy cranked up and he and his crony getting into
+the car were about to start off.
+
+"Hold on!" cried Tom. "You'll take that log from across the road or
+I'll have you arrested for obstructing traffic, and that's a serious
+offense."
+
+"I'm goin' to take it away!" growled Andy. "Give a fellow a show can't
+you?"
+
+He cast an ugly look at Tom, but the latter only smiled. It was no
+easy task for Sam and Andy to pull the log out of the way, as they
+could hardly lift it to slip the rope under. But they finally managed
+it, and, by the power of the car, hauled it to one side. Then they
+speed off.
+
+"I 'clar t' gracious, dem young fellers am most as mean an' contrary as
+mah mule Boomerang am sometimes," observed Eradicate. "Only Boomerang
+ain't quite so mean as dat."
+
+"I should hope not, Rad," observed Tom. "I'm ever so much obliged for
+your warning. I guess I'll be getting, home now. Come around next
+week; we have some work for you."
+
+"'Deed an' I will," replied the colored man. "I'll come around an'
+eradicate all de dirt on yo' place, Mistah Swift. Yais, sah, I's
+Eradicate by name, and dat's my perfession--eradicatin' dirt. Much
+obleeged, I'll call around. Giddap, Boomerang!"
+
+The mule lazily flicked his ears, but did not stir, and Tom, knowing
+the process of arousing the animal would take some time, hurried up the
+hill to where he had left his motor-cycle. Eradicate was still engaged
+on the task of trying to arouse his steed to a sense of its duty when
+the young inventor flashed by on his way home.
+
+"So now you own a broken motor-boat," observed Mr. Swift when Tom had
+related the circumstances of the auction. "Well, now you have it, what
+are you going to do with it?"
+
+"Fix it, first of all," replied his son. "It needs considerable
+tinkering up, but nothing but what I can do, if you'll help me."
+
+"Of course I will. Do you think you can get any speed out of it?"
+
+"Well, I'm not so anxious for speed. I want a good, comfortable boat,
+and the ARROW will be that. I've named it, you see. I'm going back to
+Lanton this afternoon, take some tools along, and repair it so I can
+run the boat over to here. Then I'll get at it and fix it up. I've
+got a plan for you, dad."
+
+"What is it?" asked the inventor, his rather tired face lighting up
+with interest.
+
+"I'm going to take you on a vacation trip."
+
+"A vacation trip?"
+
+"Yes, you need a rest. You've been working too hard over that
+gyroscope invention."
+
+"Yes, Tom, I think I have," admitted Mr. Swift. "But I am very much
+interested in it, and I think I can get it to work. If I do it will
+make a great difference in the control of aeroplanes. It will make
+them more stable and able to fly in almost any wind. But I certainly have
+puzzled my brains over some features of it. However, I don't quite see
+what you mean."
+
+"You need a rest, dad," said Mr. Swift's son kindly. "I want you to
+forget all about patents, invention, machinery and even the gyroscope
+for a week or two. When I get my motor-boat in shape I'm going to take
+you and Ned Newton up the lake for a cruise. We can camp out, or, if
+we had to, we could sleep in the boat. I'm going to put a canopy on it
+and arrange some bunks. It will do you good and perhaps new ideas for
+your gyroscope may come to you after a rest."
+
+"Perhaps they will, Tom. I am certainly tired enough to need a
+vacation. It's very kind of you to think of me in connection with your
+boat. But if you're going to get it this afternoon you'd better start
+if you expect to get back by night. I think Mrs. Baggert has dinner
+ready."
+
+After the meal Tom selected a number of tools from his own particular
+machine shop and carried them down to the dock on the lake, where his
+two small boats were tied.
+
+"Aren't you going back on your motor-cycle?" asked his father.
+
+"No, Dad, I'm going to row over to Lanton, and, if I can get the ARROW
+fixed, I'll tow my rowboat back."
+
+"Very well, then you won't be in any danger from Andy Foger. I must
+speak to his father about him."
+
+"No, dad, don't," exclaimed the young inventor quickly. "I can fight
+my own battles with Andy. I don't fancy he will bother me again right
+away."
+
+Tom found it more of a task than he had anticipated to get the motor in
+shape to run the ARROW back under her own power. The magneto was out
+of order and the batteries needed renewing, while the spark coil had
+short-circuited and took considerable time to adjust. But by using
+some new dry cells, which Mr. Hastings gave him, and cutting out the
+magneto, or small dynamo which produces the spark that exploded the
+gasoline in the cylinders, Tom soon had a fine, "fat" hot spark from
+the auxiliary ignition system. Then, adjusting the timer and throttle
+on the engine and seeing that the gasoline tank was filled, the lad
+started up his motor. Mr. Hastings helped him, but after a few turns
+of the flywheel there were no explosions. Finally, after the
+carburetor (which is the device where gasoline is mixed with air to
+produce an explosive mixture) had been adjusted, the motor started off
+as if it had intended to do so all the while and was only taking its
+time about it.
+
+"The machine doesn't run as smooth as it ought to," commented Mr.
+Hastings. "No, it needs a thorough overhauling," agreed the owner of
+the ARROW. "I'll get at it to-morrow," and with that he swung out into
+the lake, towing his rowboat after him.
+
+"A motor-boat of my own!" exulted Tom as he twirled the steering wheel
+and noted how readily the craft answered her helm. "This is great!"
+
+He steered down the lake and then, turning around, went up it a mile or
+more before heading for his own dock, as he wanted to see how the
+engine behaved.
+
+"With some changes and adjustments I can make this a speedy boat,"
+thought Tom. "I'll get right at it. I shouldn't wonder if I could
+make a good showing against Mr. Hastings' new CARLOPA, though his
+boat's got four cylinders and mine has but two."
+
+The lad was proceeding leisurely along the lakeshore, near his home,
+with the motor throttled down to test it at low speed, when he heard
+some one shout. Looking toward the bank, Tom saw a man waving his
+hands.
+
+"I wonder what he wants?" thought our hero as he put the wheel over to
+send his craft to shore. He heard a moment later, for the man on the
+bank cried:
+
+"I say, my young friend, do you know anything about automobiles? Of
+course you do or you wouldn't be running a motor-boat. Bless my very
+existence, but I'm in trouble! My machine has stopped on a lonely road
+and I can't seem to get it started. I happened to hear your boat and I
+came here to hail you. Bless my coat-pockets but I am in trouble! Can
+you help me? Bless my soul and gizzard!"
+
+"Mr. Damon!" exclaimed Tom, shutting off the power, for he was now near
+shore. "Of course I'll help you, Mr. Damon," for the young inventor
+had recognized the eccentric man of whom he had purchased the
+motor-cycle and who had helped him in rounding up the thieves.
+
+"Why, bless my shoe-laces, if it isn't Tom Swift!" exclaimed Mr. Damon,
+who seemed very fond of calling down blessings upon himself or upon
+articles of his dress or person.
+
+"Yes! I'm here," admitted Tom with a laugh.
+
+"And in a motor-boat, too! Bless my pocketbook, but did that run away
+with some one who sold it to you cheap?"
+
+"No, not exactly," and the lad explained how he had come into
+possession of it. By this time he was ashore and had tied the ARROW to
+an overhanging tree. Then Tom proceeded to where Mr. Damon had left
+his stalled automobile. The eccentric man was wealthy and his
+physician had instructed him to ride about in the car for his health.
+Tom soon located the trouble. The carburetor had become clogged, and
+it was soon in working order again.
+
+"Well, now that you have a boat, I don't suppose you will be riding
+about the country so much," commented Mr. Damon as he got into his car.
+"Bless my spark-plug! But if you ever get over to Waterfield, where I
+live, come and see me. It's handy to get to by water."
+
+"I'll come some day," promised the lad.
+
+"Bless my hat band, but I hope so," went on the eccentric individual as
+he prepared to start his car.
+
+Tom completed the remainder of the trip to his house without incident
+and his father came down to the dock to see the motor-boat. He agreed
+with his son that it was a bargain and that it could easily be put in
+fine shape.
+
+The youth spent all the next day and part of the following working on
+the craft. He overhauled the ignition system, which was the jump-spark
+style, cleaned the magneto and adjusted the gasoline and compression
+taps so that they fitted better. Then he readjusted the rudder lines,
+tightening them on the steering wheel, and looked over the piping from
+the gasoline tank.
+
+The tank was in the forward compartment, and, upon inspecting this, the
+lad concluded to change the plan by which the big galvanized iron box
+was held in place. He took out the old wooden braces and set them
+closer together, putting in a few new ones.
+
+"The tank will not vibrate so when I'm going at full speed," he
+explained to his father.
+
+"Is that where the strange man was tampering with the lock the day of
+the auction?" asked Mr. Swift.
+
+"Yes, but I don't see what he could want in this compartment, do you
+dad?"
+
+The inventor got into the boat and looked carefully into the rather
+dark space where the tank fitted. He went over every inch of it, and,
+pointing to one of the thick wooden blocks that supported the tank,
+asked:
+
+"Did you bore that hole in there, Tom?"
+
+"No, it was there before I touched the braces. But it isn't a hole, or
+rather, someone bored it and stopped it up again. It doesn't weaken
+the brace any."
+
+"No, I suppose not. I was just wondering whether that was one of the
+new blocks or an old one."
+
+"Oh, an old one. I'm going to paint them, too, so in case the water
+leaks in or the gasoline leaks out the wood won't be affected. A
+gasoline tank should vibrate as little as possible, if you don't want
+it to leak. I guess I'll paint the whole interior of this compartment
+white, then I can see away into the far corners of it."
+
+"I think that's a good idea," commented Mr. Swift.
+
+It was four days after his purchase of the boat before Tom was ready to
+make a long trip in it. Up to that time he had gone on short spins not
+far from the dock, in order to test the engine adjustment. The lad
+found it was working very well, but he decided with a new kind of spark
+plugs for the two cylinders that he could get more speed out of it.
+Finally the forward compartment was painted and a general overhauling
+given the hull and Tom was ready to put his boat to a good test.
+
+"Come on, Ned," he said to his chum early one evening after Mr. Swift
+had said he was too tired to go out on a trial run. "We'll see what
+the ARROW will do now."
+
+From the time Tom started up the motor it was evident that the boat was
+going through the water at a rapid rate. For a mile or more the two
+lads speeded along, enjoying it hugely. Then Ned exclaimed:
+
+"Something's coming behind us."
+
+Tom turned his head and looked. Then he called out:
+
+"It's Mr. Hastings in his new CARLOPA. I wonder if he wants a race?"
+
+"Guess he'd have it all his own way," suggested Ned.
+
+"Oh, I don't know. I can get a little more speed out of my boat."
+
+Tom waited until the former owner of the ARROW was up to him.
+
+"Want a race?" asked Mr. Hastings good-naturedly.
+
+"Sure!" agreed Tom, and he shoved the timer ahead to produce quicker
+explosions.
+
+The ARROW seemed to leap forward and for a moment was ahead of the
+CARLOPA, but with a motion of his hand to the spark lever Mr. Hastings
+also increased his speed. For a moment the two boats were on even
+terms and then the larger and newer one forged ahead. Tom had expected
+it, but he was a little disappointed.
+
+"That's doing first rate," complimented Mr. Hastings as he passed them.
+"Better than I was ever able to make her do even when she was new, Tom."
+
+This made the present owner of the ARROW feel somewhat consoled. He
+and Ned ran on for a few miles, the CARLOPA in the meanwhile
+disappearing from view around a bend. Then Tom and his chum turned
+around and made for the Swift dock.
+
+"She certainly is a dandy!" declared Ned. "I wish I had one like it."
+
+"Oh, I intend that you shall have plenty of rides in this," went on his
+friend. "When you get your vacation, you and dad and I are going on a
+tour," and he explained his plan, which, it is needless to say, met
+with Ned's hearty approval.
+
+Just before going to bed, some hours later, Tom decided to go down to
+the dock to make sure he had shut off the gasoline cock leading from
+the tank of his boat to the motor. It was a calm, early summer night,
+with a new moon giving a little light, and the lad went down to the
+lake in his slippers. As he neared the boathouse he heard a noise.
+
+"Water rat," he murmured, "or maybe muskrats. I must set some traps."
+
+As Tom entered the boathouse he started back in alarm, for a bright
+light flashed up, almost in his eyes.
+
+"Who's here?" he cried, and at that moment someone sprang out of his
+motor-boat, scrambled into a rowing craft which the youth could dimly
+make out in front of the dock and began to pull away quickly.
+
+"Hold on there!" cried the young inventor. "Who are you? What do you
+want? Come back here!"
+
+The person in the 'coat returned no answer. With his heart doing beats
+over-time Tom lighted a lantern and made a hasty examination of the
+ARROW. It did not appear to have been harmed, but a glance showed that
+the door of the gasoline compartment had been unlocked and was open.
+Tom jumped down into his craft.
+
+"Some one has been at that compartment again!" he murmured. "I wonder
+if it was the same man who acted so suspiciously at the auction? What
+can his object be, anyhow?"
+
+The next moment he uttered an exclamation of startled surprise and
+picked up something from the bottom of the boat. It was a bunch of
+keys, with a tag attached, bearing the owner's name.
+
+"Andy Foger!" murmured Tom. "So this is, how he was trying to get
+even! Maybe he started to put a hole in the tank or in my boat."
+
+
+
+
+CHAPTER VI
+
+TOWING SOME GIRLS
+
+
+With a sense of anger mingled with an apprehension lest some harm
+should have been done to his craft, the owner of the ARROW went
+carefully over it. He could find nothing wrong. The engine was all
+right and all that appeared to have been accomplished by the unbidden
+visitor was the opening of the locked forward compartment. That this
+had been done by one of the many keys on Andy Foger's ring was evident.
+
+"Now what could have been his object?" mused Tom. "I should think if
+he wanted to put a hole in the boat he would have done it amidships,
+where the water would have a better chance to come in, or perhaps he
+wanted to flood it with gasoline and--"
+
+The idea of fire was in Tom's mind, and he did not finish his
+half-completed thought.
+
+"That may have been it," he resumed after a hasty examination of the
+gasoline tank, to make sure there were no leaks in it. "To get even
+with me for outbidding him on the boat, Andy may have wanted to destroy
+the ARROW. Well, of all the mean tricks, that's about the limit! But
+wait until I see him. I've got evidence against him," and Tom looked
+at the key ring. "I could almost have him arrested for this."
+
+Going outside the boathouse, Tom stood on the edge of the dock and
+peered into the darkness. He could hear the faint sound of someone
+rowing across the lake, but there was no light.
+
+"He had one of those electric flash lanterns," decided Tom. "If I
+hadn't found his keys, I might have thought it was Happy Harry instead
+of Andy."
+
+The young inventor went back into the house after carefully locking the
+boat compartment and detaching from the engine an electrical device,
+without which the motor in the ARROW could not be started.
+
+"That will prevent them from running away with my boat, anyhow,"
+decided Tom. "And I'll tell Garret Jackson to keep a sharp watch
+to-night." Jackson was the engineer at Mr. Swift's workshop.
+
+Tom told his father of the happening and Mr. Swift was properly
+indignant. He wanted to go at once to see Mr. Foger and complain of
+Andy's act, but Tom counseled waiting.
+
+"I'll attend to Andy myself," said the young inventor. "He's getting
+desperate, I guess, or he wouldn't try to set the place on fire. But
+wait until I show him these keys."
+
+Bright and early the next morning the owner of the motor-boat was down
+to the dock inspecting it. The engineer, who had been on watch part of
+the night, reported that there had been no disturbance, and Tom found
+everything all right. "I wonder if I'd better go over and accuse Andy
+now or wait until I see him and spring this evidence on him?" thought
+our hero. Then he decided it would be better to wait. He took the
+ARROW out after breakfast, his father going on a short spin with him.
+
+"But I must go back now and work on my gyroscope invention," said Mr.
+Swift when about two hours had been spent on the lake. "I am making
+good progress with it."
+
+"You need a vacation," decided Tom, "I'll be ready to take you and Ned
+in about two weeks. He will have two weeks off then and, we'll have
+some glorious times together."
+
+That afternoon Tom put some new style spark plugs in the cylinders of
+his motor and found that he had considerably increased the revolutions
+of the engine, due to a better explosion being obtained. He also made
+some minor adjustments and the next day he went out alone for a long
+run.
+
+Heading up the lake, Tom was soon in sight of a popular excursion
+resort that was frequently visited by church and Sunday-school
+organizations in the vicinity of Shopton. The lad saw a number of
+rowing craft and a small motor-boat circling around opposite the resort
+and remarked: "There must be a picnic at the grove to-day. Guess I'll
+run up and take a look."
+
+The lad was soon in the midst of quite a flotilla of rowboats, most of
+them manned by pretty girls or in charge of boys who were giving
+sisters (their own or some other chap's) a trip on the water. Tom
+throttled his boat down to slow speed and looked with pleasure on the
+pretty scene. His boat attracted considerable attention, for motor
+craft were not numerous on Lake Carlopa.
+
+As our hero passed a boat, containing three very pretty young ladies,
+Tom heard one of them exclaim:
+
+"There he is now! That's Tom Swift."
+
+Something in the tones of the voice attracted his attention. He turned
+and saw a brown-eyed girl smiling at him. She bowed and asked,
+blushing the while:
+
+"Well, have you caught any more runaway horses lately?"
+
+"Runaway horses--why--what? Oh, it's Miss Nestor!" exclaimed the lad,
+recognizing the young lady whose steed he had frightened one day when
+he was on his bicycle. As told in the first volume of this series, the
+horse had run away, being alarmed at the flashing of Tom's wheel, and
+Miss Mary Nestor, of Mansburg, was in grave danger.
+
+"So you've given up the bicycle for the motor-boat," went on the young
+lady.
+
+"Yes," replied Tom with a smile, shutting off the power, "and I haven't
+had a chance to save any girls since I've had it."
+
+The two boats had drifted close together, and Miss Nestor introduced
+her two companions to Tom.
+
+"Don't you want to come in and take a ride?" he asked.
+
+"Is it safe?" asked Jennie Haddon, one of the trio.
+
+"Of course it is, Jennie, or he wouldn't be out in it," said Miss
+Nestor hastily. "Come on, let's get in. I'm just dying for a
+motor-boat ride."
+
+"What will we do with our boat?" asked Katie Carson.
+
+"Oh, I can tow that," replied the youth. "Get right in and I'll take
+you all around the lake."
+
+"Not too far," stipulated the girl who had figured in the runaway. "We
+must be back for lunch, which will be served in about an hour. Our
+church and Sunday-school are having a picnic."
+
+"Maybe Mr. Swift will come and have some lunch with us," suggested Miss
+Carson, blushing prettily.
+
+"Nothing would give me greater pleasure," answered Tom, and then he
+laughed at his formal reply, the girls joining in.
+
+"We'd be glad to have you," added Miss Haddon. "Oh!" she suddenly
+screamed, "the boat's tipping over!"
+
+"Oh, no," Tom hastened to assure her, coming, to the side to help her
+in. "It just tilts a bit, with the weight of so many on one side. It
+couldn't capsize if it tried."
+
+In another moment the three were in the roomy cockpit and Tom had made
+the empty rowboat fast to the stern. He was about to start up when
+from another boat, containing two little girls and two slightly larger
+boys, came a plaintive cry:
+
+"Oh, mister, give us a ride!"
+
+"Sure!" agreed Tom pleasantly. "Just fasten your boat to the other
+rowboat and I'll tow you."
+
+One of the boys did this, and then, with three pretty girls as his
+companions in the ARROW and towing the two boats, Tom started off.
+
+The girls were very much interested in the craft and asked all sorts of
+questions about how the engine operated. Tom explained as clearly as
+he could how the gasoline exploded in the cylinders, about the electric
+spark and about the propeller. Then, when he had finished, Miss Haddon
+remarked naively:
+
+"Oh, Mr. Swift, you've explained it beautifully, and I'm sure if our
+teacher in school made things as clear as you have that I could get
+along fine. I understand all about it, except I don't see what makes
+the engine go."
+
+"Oh," said Tom faintly, and he wondering what would be the best remark
+to make under the circumstances, when Miss Nestor created a diversion
+by looking at her watch and exclaiming:
+
+"Oh, girls, it's lunch time! We must go ashore. Will you kindly put
+about, Mr. Swift--I hope that is the proper term--and--land us--is that
+right?" and she looked archly at Tom.
+
+"That's perfectly right," he admitted with a laugh and a glance into
+the girl's brown eyes. "I'll put you ashore at once," and he headed
+for a small dock.
+
+"And come yourself to take lunch with us, added Miss Haddon.
+
+"I'm afraid I might be in the way," stammered Tom. "I--I have a pretty
+good appetite, and--"
+
+"I suppose you think that girls on a picnic don't take much lunch,"
+finished Miss Nestor. "But I assure you that we have plenty, and that
+you will be very welcome," she added warmly.
+
+"Yes, and I'd like to have him explain over again how the engine
+works," went on Miss Haddon. "I am so interested."
+
+Tom helped the girls out, receiving their thanks as well as those of
+the children in the second boat. But as he walked with the young
+ladies through the grove the young inventor registered a mental vow
+that he would steer clear of explaining again how a gasoline engine
+worked.
+
+"Now come right over this way to our table," invited Miss Nestor. "I
+want you to meet papa and mamma."
+
+Tom followed her. As he stepped from behind a clump of trees he saw,
+standing not far away, a figure that seemed strangely familiar. A
+moment later the figure turned and Tom saw Andy Foger confronting him.
+At the sight of our hero the bully turned red and walked quickly away,
+while Tom's fingers touched the ring of keys in his pocket.
+
+
+
+
+CHAPTER VII
+
+A BRUSH WITH ANDY
+
+
+So unexpected was his encounter with Andy that the young inventor
+hardly knew how to act, especially since he was a guest of the young
+ladies. Tom did not want to do or say anything to embarrass them or
+make a scene, yet he did want to have a talk, and a very serious talk,
+with Andy Foger.
+
+Miss Nestor must have noticed Tom's sudden start at his glimpse of
+Andy, for she asked: "Did you see some one you knew, Mr. Swift?"
+
+"Yes," replied Tom, "I did--er--that is--" He paused in some confusion.
+
+"Perhaps you'd like---that is prefer--to go with them instead of taking
+lunch with girls who don't know anything about engines?" she persisted.
+
+"Oh, no indeed," Tom hastened to assure her. "He--that is--the person
+I saw wouldn't care to have me lunch with him," and the youth smiled
+grimly.
+
+"Would you like to bring him over to our table?" inquired Miss Carson.
+"We have plenty for him."
+
+"No, I think that would hardly do," continued the lad, who tried not to
+smile at the picture of the red-haired and squint-eyed Andy Foger
+making one of a party with the girls. The young ladies fortunately had
+not noticed the bully, who was out of view by this time.
+
+Tom was presented to Mr. and Mrs. Nestor, who told him how glad they
+were to meet the young man who had been instrumental in saving their
+daughter from injury, if not death. Tom was a bit embarrassed, but
+bore the praise as well as he could, and he was very glad when a
+diversion, in the shape of lunch, occurred.
+
+After a meal on tables under the trees in the grove Tom took the girls
+and some of their friends out in his motor-boat again. They covered
+several miles around the lake before returning to the picnic ground.
+
+As Tom was starting toward home in his boat, wondering what had become
+of Andy and trying to think of a reason why the bully should attend
+anything as "tame" as a church picnic, the object of his thoughts came
+strolling through the trees down to the shore of the lake. The moment
+he saw Tom the red-haired lad started back, but the young inventor,
+leaping out of his boat, called out:
+
+"Hold on there, Andy Foger, I want to see you!" and there was menace in
+Tom's tone.
+
+"But, I don't want to see you!" retorted the other sulkily. "I've got
+no use for you."
+
+"No more have I for you," was Tom's quick reply. "But I want to return
+you these keys. You dropped them in my boat the other night when you
+tried to set it afire. If I ever catch you--"
+
+"My keys! Your boat! On fire!" gasped Andy, so plainly astonished
+that Tom knew his surprise was genuine.
+
+"Yes, your keys. You were a little too quick for me or I'd have
+caught you at it. The next time you pick a lock don't leave your keys
+behind you," and he held out the jingling ring.
+
+Andy Foger advanced slowly. He took the bunch of keys and looked at
+the tag.
+
+"They are mine," he said slowly, as if there was some doubt about it.
+
+"Of course they are," declared Tom. "I found them where you dropped
+them--in my boat."
+
+"Do you mean over at the auction?"
+
+"No, I mean down in my boathouse, where you sneaked in the other night
+and tried to do some damage.
+
+"The other night!" cried Andy. "I never was near your boathouse any
+night and I never lost my keys there! I lost these the day of the
+auction, on Mr. Hastings' ground, and I've been looking for them ever
+since."
+
+"Didn't you sneak in my boathouse the other night and try to do some
+mischief? Didn't you drop them then?"
+
+"No, I didn't," retorted Andy earnestly. "I lost those keys at the
+auction, and I can prove it to you. Look, I advertised for them in the
+weekly Gazette."
+
+The red-haired lad pulled a crumpled paper from his pocket and showed
+Tom an advertisement offering a reward of two dollars for a bunch of
+keys on a ring, supposed to have been lost at the auction on Mr.
+Hastings' grounds in Lanton. The finder was to return them to Andy
+Foger.
+
+"Does that look as if I lost the keys in your boathouse?" demanded the
+bully sneeringly. "I wouldn't have advertised them that way if I'd been
+trying to keep my visit quiet. Besides, I can prove that I was out of
+town several nights. I was over to an entertainment in Mansburg one
+night and I didn't get home until two o'clock in the morning, because
+my machine broke down. Ask Ned Newton. He saw me at the
+entertainment."
+
+Andy's manner was so earnest that Tom could not help believing him.
+Then there was the evidence of the advertisement. Clearly the
+squint-eyed youth had not been the mysterious visitor to the boathouse
+and had not unlocked the forward compartment. But if it was not he,
+who could it have been and how did the keys get there? These were
+questions which racked Tom's brain.
+
+"You can ask Ned Newton," repeated Andy. "He'll prove that I couldn't
+have been near your place, if you don't believe me."
+
+"Oh, I believe you all right," answered Tom, for there could be no
+doubting Andy's manner, even though he and the young inventor were not
+on good terms. "But how did your keys get in my boat?"
+
+"I don't know, unless you found them, kept them and dropped them
+there," was the insolent answer.
+
+"You know better than that," exclaimed Tom.
+
+"Well, I owe you a reward of two dollars for giving them back to me,"
+continued the bully patronizingly. "Here it is," and he hauled out
+some bills.
+
+"I don't want your money!" fired back Tom.
+
+"But I'd like to know who it was that was in my boat."
+
+"And I'd like to know who it was took my keys," and Andy stuffed the
+money back in his pocket. Tom did not answer. He was puzzling over a
+queer matter and he wanted to be alone and think. He turned aside from
+the red-haired lad and walked toward his motor-boat.
+
+"I'll give you a surprise in a few days," Andy called after him, but
+Tom did not turn his head nor did he inquire what the surprise might be.
+
+Mr. Swift was somewhat puzzled when his son related the outcome of the
+key incident. He agreed with Tom that some one might have found the
+ring and kept it, and that the same person might have been the one whom
+Tom had surprised in the boathouse.
+
+"But it's idle to speculate on it," commented the inventor. "Andy
+might have induced some of his chums to act for him in harming your
+boat, and the key advertisement might have been only a ruse."
+
+"I hardly think so," answered his son, shaking his head. "It strikes
+me as being very curious, and I'm going to see if I can't get at the
+bottom of it."
+
+But a week or more passed and Tom had no clew. In the meanwhile he was
+working away at his motor-boat, installing several improvements.
+
+One of these was a better pump, which circulated the water around the
+cylinders, and another was a new system of lubrication under forced
+feed.
+
+"This ought to give me a little more speed," reasoned Tom, who was not
+yet satisfied with his craft. "Guess I'll take it out for a spin."
+
+He was alone in the ARROW, taking a long course up the lake when, as he
+passed a wooded point that concealed from view a sort of bay, he heard
+the puffing of another motor-boat.
+
+"Maybe that's Mr. Hastings," thought Tom. "If I raced with him now, I
+think the ARROW could give a better account of herself."
+
+The young inventor looked at the boat as it came into view. It needed
+but a glance to show that it was not the CARLOPA. Then, as it came
+nearer, Tom saw a familiar figure in it--a red-haired, squint-eyed chap.
+
+"Andy Foger!" exclaimed Tom. "He's got a motor-boat! This is the
+surprise he spoke of."
+
+The boat was rapidly approaching him, and he saw that it was painted a
+vivid red. Then he could make out the name on the bow, RED STREAK.
+Andy was sending the craft toward him at a fast rate.
+
+"You needn't think you're the only one on this lake who has a gasoline
+boat!" called Andy boastfully. "This is my new one and the fastest
+thing afloat around here. I can go all around you. Do you want to
+race?"
+
+It was a "dare," and Tom never took such things when he could
+reasonably enter a contest. He swung his boat around so as to shoot
+alongside of Andy and answered:
+
+"Yes, I'll race you. Where to?"
+
+"Down opposite Kolb's dock and back to this point," was the answer.
+"I'll give you a start, as my engine has three cylinders. This is a
+racing boat."
+
+"I don't need any start," declared Tom. "I'll race you on even terms.
+Go ahead!"
+
+Both lads adjusted their timers to get more speed. The water began to
+curl away from the sharp prows, the motors exploded faster and faster.
+The race was on between the ARROW and the RED STREAK.
+
+
+
+
+CHAPTER VIII
+
+OFF ON A TRIP
+
+
+Glancing with critical eyes at the craft of his rival, Tom saw that
+Andy Foger had a very fine boat. The young inventor also realized that
+if he was to come anywhere near winning the race he would have to get
+the utmost speed out of his engine, for the new boat the bully had was
+designed primarily for racing, while Tom's was an all-around pleasure
+craft, though capable of something in the speed line.
+
+"I'll be giving you a tow in a few minutes, as soon as my engine gets
+warmed up!" sneered Andy.
+
+"Maybe," said Tom, and then he crouched down to make as little
+resistance as possible to the wind. Andy, on the contrary, sat boldly
+upright at the auto steering wheel of his boat.
+
+On rushed the two motor craft, their prows exactly even and the
+propellers tossing up a bulge in the water at their sterns. Rapidly
+acquiring speed after the two lads had adjusted the timers on their
+motors, the boats were racing side by side, seemingly on even terms.
+
+The RED STREAK had a very sharp prow, designed to cut through the
+water. It was of the type known as an automobile launch. That is, the
+engine was located forward, under a sort of hood, which had two hinged
+covers like a bat's wings. The steering-wheel shaft went through the
+forward bulkhead, slantingly, like the wheel of an auto, and was
+arranged with gasoline and sparking levers on the center post in a
+similar manner. At the right of the wheel was a reversing lever, by
+which the propeller blades could be set at neutral, or arranged so as
+to drive the boat backward. Altogether the RED STREAK was a very fine
+boat and had cost considerably more than had Tom's, even when the
+latter was new. All these things the young owner of the ARROW thought
+of as he steered his craft over the course.
+
+"I hardly think I can win," Tom remarked to himself in a whisper. "His
+boat is too speedy for this one. I have a chance, though, for his
+engine is new, and I don't believe he understands it as well as I do
+mine. Then, too, I am sure I have a better ignition system."
+
+But if Tom had any immediate hopes of defeating Andy, they were doomed
+to disappointment, for about two minutes after the race started the RED
+STREAK forged slowly ahead.
+
+"Come on!" cried the red-haired lad. "I thought you wanted a race."
+
+"I do," answered the young inventor. "We're a long way from the dock
+yet, and we've got to come back."
+
+"You'll be out of it by the time I get to the dock," declared Andy.
+
+Indeed it began to look so, for the auto boat was now a full length
+ahead of Tom's craft and there was open water between them. But our
+hero knew a thing or two about racing, though he had not long been a
+motor-boat owner. He adjusted the automatic oiler on the cylinders to
+give more lubrication, as he intended to get more speed out of his
+engine. Then he opened the gasoline cock a trifle more and set his
+timer forward a few notches to get an earlier spark. He was not going
+to use the maximum speed just yet, but he first wanted to see how the
+motor of the ARROW would behave under these conditions. To his delight
+he saw his boat slowly creeping up on Andy's. The latter, with a
+glance over his shoulder, saw it too, and he advanced his spark. His
+craft forged ahead, but the rate of increase was not equal to Tom's.
+"If I can keep up to him I suppose I ought to be glad," thought the
+young inventor, "for his boat is away ahead of mine in rating."
+
+Through the water the sharp bows cut. There were only a few witnesses
+to the race, but those who were out in boats saw a pretty sight as the
+two speedy craft came on toward the dock, which was the turning point.
+
+Andy's boat reached it first, and swung about in a wide circle for the
+return. Tom decided it was time to make his boat do its best, so he
+set the timer at the limit, and the spark, coming more quickly,
+increased the explosions.
+
+Up shot the ARROW and, straightening out after the turn, Tom's craft
+crept along until it lapped the stern of the RED STREAK. Andy looked
+back in dismay. Then he tried to get more speed out of his engine. He
+did cause the screw to revolve a little faster, and Tom noted that he
+was again being left behind. Then one of those things, which may
+happen at any time to a gasoline motor, happened to Andy's. It began
+to miss explosions. At first it was only occasionally, then the misses
+became more frequent.
+
+The owner of the RED STREAK with one hand on the steering wheel, tried
+with the other to adjust the motor to get rid of the trouble, but he
+only made it worse. Andy's boat began to fall back and Tom's to creep
+up. Frantically Andy worked the gasoline and sparking levers, but
+without avail. At last one cylinder went completely out of service.
+
+The two boats were now on even terms and were racing along side by side
+toward the wooded, point, which marked the finish.
+
+"I'll beat you yet!" exclaimed Andy fiercely.
+
+"Better hurry up!" retorted Tom.
+
+But the young inventor was not to have it all his own way. With a
+freakishness equal to that with which it had ceased to explode the dead
+cylinder came to life again, and the RED STREAK shot ahead. Once more
+Andy's boat had the lead of a length and the finish of the race was
+close at hand. The squint-eyed lad turned and shouted: "I told you I'd
+beat you! Want a tow now?"
+
+It began to look as though Tom would need it, but he still had
+something in reserve. One of the improvements he had put in the ARROW
+was a new auxiliary ignition system. This he now decided to use.
+
+With a quick motion Tom threw over the switch that put it into
+operation. A hotter, "fatter" spark was at once produced, and
+adjusting his gasoline cock so that a little more of the fluid would be
+drawn in, making a "richer" mixture, the owner of the ARROW saw the
+craft shoot forward as if, like some weary runner, new life had been
+infused.
+
+In vain did Andy frantically try to get more speed out of his motor.
+He cut out the muffler, and the explosions sounded loudly over the
+lake. But it was no use. A minute later the ARROW, which had slowly
+forged ahead, crossed the bows of the RED STREAK opposite the finishing
+point, and Tom had won the race.
+
+"Well, was that fair?" our hero called to Andy, who had quickly shut
+off some of his power as he saw his rival's daring trick. "Did I beat
+you fair?"
+
+"You wouldn't have beaten me if my engine hadn't gone back on me,"
+grumbled Andy, chagrin showing on his face. "Wait until my motor runs
+smoother and I'll give you a big handicap and beat you. My boat's
+faster than yours. It ought to be. It cost fifteen hundred dollars
+and it's a racer."
+
+"I guess it doesn't like racing," commented Tom as he swung the prow of
+his craft down the lake toward his home. But he knew there was some
+truth in what Andy had said. The RED STREAK was a more speedy boat,
+and, with proper handling, could have beaten the ARROW. That was where
+Tom's superior knowledge came in useful. "Just you wait, I'll beat you
+yet," called Andy, after the young inventor, but the latter made no
+answer. He was satisfied.
+
+Mr. Swift was much interested that night in his son's account of the
+race.
+
+"I had no idea yours was such a speedy boat," he said.
+
+"Well, it wasn't originally," admitted Tom, "but the improvements I put
+on it made it so. But, dad, when are we going on our tour? You look
+more worn out than I've seen you in some time, not excepting when the
+turbine model was stolen. Are you worrying over your gyroscope
+invention?"
+
+"Somewhat, Tom. I can't seem to hit on just what I want. It's a
+difficult problem."
+
+"Then I tell you what let's do, dad. Let's drop everything in the
+inventive line and go off on a vacation. I'll take you up the lake in
+my boat and you can spend a week at the Lakeview Hotel at Sandport. It
+will do you good."
+
+"What will you do, Tom?"
+
+"Oh, Ned Newton and I will cruise about and we'll take you along any
+time you want to go. We're going to camp out nights or sleep in the
+boat if it rains. I've ordered a canopy with side curtains. Ned and I
+don't care for the hotel life in the summer. Will you go?"
+
+Mr. Swift considered a moment. He did need a rest, for he had been
+working hard and his brain was weary with thinking of many problems.
+His son's program sounded very attractive.
+
+"I think I will accept," said the inventor with a smile. "When can you
+start, Tom?"
+
+"In about four days. Ned Newton will get his vacation then and I'll
+have the canopy on. I'll start to work at it to-morrow. Then we'll go
+on a trip."
+
+Sandport was a summer resort at the extreme southern end of Lake
+Carlopa, and Mr. Swift at once wrote to the Lakeview Hotel there to
+engage a room for himself. In the meanwhile Tom began to put the
+canopy on his boat and arrange for the trip, which would take nearly a
+whole day. Ned Newton was delighted with the prospect of a camping
+tour and helped Tom to get ready. They took a small tent and plenty of
+supplies, with some food. They did not need to carry many rations, as
+the shores of the lake were lined with towns and villages where food
+could be procured.
+
+Finally all was ready for the trip and the night before the start Ned
+Newton stayed at Tom's house so as to be in readiness for going off
+early in the morning. The day was all that could be desired, Tom
+noted, as he and his chum hurried down to the dock before breakfast to
+put their blankets in the boat. As the young inventor entered the
+craft he uttered an exclamation.
+
+"What's the matter?" asked Ned.
+
+"I was sure I locked the sliding door of that forward compartment," was
+the reply. "Now it's open." He looked inside the space occupied by
+the gasoline tank and cried out: "One of the braces is gone! There's
+been some one at my boat in the night and they tried to damage her."
+
+"Much harm done?" asked Ned anxiously.
+
+"No, none at all, to speak of," replied Tom. "I can easily put a new
+block under the tank. In fact, I don't really need all I have. But
+why should any one take one out, and who did it? That's what I want to
+know."
+
+The two lads looked carefully about the dock and boat for a sign of the
+missing block or any clews that might show who had been tampering with
+the ARROW, but they could find nothing.
+
+"Maybe the block fell out," suggested Ned.
+
+"It couldn't," replied Tom. "It was one of the new ones I put in
+myself and it was nailed fast. You can see where it's been pried
+loose. I can't understand it," and Tom thought rapidly of several
+mysterious occurrences of late in which the strange man at the auction
+and the person he had surprised one night in the boathouse had a part.
+
+"Well, it needn't delay our trip," resumed the young inventor. "Maybe
+there's a hoodoo around here, and it will do us good to get away a few
+days. Come on, we'll have breakfast, get dad and start."
+
+A little later the ARROW was puffing away up the lake in the direction
+of Sandport.
+
+
+
+
+CHAPTER IX
+
+MR. SWIFT IS ALARMED
+
+
+"Don't you feel better already, dad?" asked Tom that noon as they
+stopped under a leaning, overhanging tree for lunch on the shore of the
+lake. "I'll leave it to Ned if you don't look more contented and less
+worried."
+
+"I believe he does," agreed the other lad. "Well, I must say I
+certainly have enjoyed the outing so far," admitted the inventor with a
+smile. "And I haven't been bothering about my gyroscope. I think I'll
+take another sandwich, Tom, and a few more olives."
+
+"That's the way to talk!" cried the son. "Your appetite is improving,
+too. If Mrs. Baggert could see you she'd say so."
+
+"Oh, yes, Mrs. Baggert. I do hope she and Garret will look after the
+house and shops well," said Mr. Swift, and the old, worried look came
+like a shadow over his face.
+
+"Now don't be thinking of that, dad," advised Tom, "Of course
+everything will be all right. Do you think some of those model thieves
+will return and try to get some of your other inventions?"
+
+"I don't know, Tom. Those men were unscrupulous scoundrels, and you
+can never tell what they might do to revenge themselves on us for
+defeating their plans."
+
+"Well, I guess Garret and Mrs. Baggert will look out for them,"
+remarked his son. "Don't worry."
+
+"Yes, it's bad for the digestion," added Ned. "If you don't mind, Tom,
+I'll have some more coffee and another sandwich myself."
+
+"Nothing the matter with your appetite, either," commented the young
+inventor as he passed the coffee pot and the plate.
+
+They were soon on their way again, the ARROW making good time up the
+lake. Tom was at the engine, making several minor adjustments to it,
+while Ned steered. Mr. Swift reclined on one of the cushioned seats
+under the shade of the canopy. The young owner of the ARROW looked
+over the stretch of water from time to time for a possible sight of
+Andy Foger, but the RED STREAK was not to be seen. The Lakeview Hotel
+was reached late that afternoon and the boat was tied up to the dock,
+while Tom and Ned accompanied Mr. Swift to see him comfortably
+established in his room.
+
+"Won't you stay to supper with me?" invited the inventor to his son and
+the latter's chum. "Or do you want to start right in on camp life?"
+
+"I guess we'll stay to supper and remain at the hotel to-night,"
+decided Tom. "We got here a little later than I expected, and Ned and
+I hardly have time to go very far and establish a temporary camp.
+We'll live a life of luxurious ease to-night and begin to be
+'wanderlusters' and get back to nature to-morrow."
+
+In the morning Tom and his chum, full of enthusiasm for the pleasures
+before them, started off, promising to come back to the hotel in a few
+days to see how Mr. Swift felt. The trip had already done the man good
+and his face wore a brighter look.
+
+Tom and Ned, in the speedy ARROW, cruised along the lakeshores all that
+morning. At noon they went ashore, made a temporary camp and arranged
+to spend the night there in the tent. After this was erected they got
+out their fishing tackle and passed the afternoon at that sport, having
+such good luck that they provided their own supper without having to
+depend on canned stuff.
+
+They lived this life for three days, making a new camp each night,
+being favored with good weather, so that they did not have to sleep in
+the boat to keep dry. On the afternoon of the third day Tom, with a
+critical glance at the sky, remarked:
+
+"I shouldn't be surprised if it rained to-morrow, Ned."
+
+"Me either. It does look sort of hazy, and the wind is in a bad
+quarter."
+
+"Then what do you say to heading for the hotel? I fancy dad will be glad
+to see us."
+
+"That suits me. We can start camp life again after the storm passes."
+
+They started for Sandport that afternoon. When within about two miles
+of the hotel dock Tom saw, just ahead of them, a small motor-boat. Ned
+observed it too and called out:
+
+"S'pose that's Andy looking for another race?"
+
+"No, the boat's too small for his. We'll put over that way and see who
+it is."
+
+The other craft did not appear to be moving very rapidly and the ARROW
+was soon overhauling it. As the two chums came nearer they could hear
+the puffing of the motor. Tom listened with critical ears.
+
+"That machine isn't working right," he remarked to his chum.
+
+At that moment there sounded a loud explosion from the other boat and
+at the same time there came over the water a shrill cry of alarm.
+"That's a girl in that boat!" exclaimed Ned. "Maybe she's hurt."
+
+"No, the motor only backfired," observed Tom. "But we'll go over and
+see if we can help her. Perhaps she doesn't understand it. Girls
+don't know much about machinery."
+
+A little later the ARROW shot up alongside the other craft, which had
+come to a stop. The two lads could see a girl bending over the motor,
+twirling the flywheel and trying to get it started. "Can I help you?"
+asked Tom, shutting off the power from his craft.
+
+The young lady glanced up. Her face was red and she seemed ill at
+ease. At the sight of the young inventor she uttered an exclamation of
+relief.
+
+"Why, Mr. Swift!" she cried. "Oh, I'm in such trouble. I can't make
+the machine work, and I'm afraid it's broken; it exploded."
+
+"Miss Nestor!" blurted out Tom, more surprised evidently to see his
+acquaintance of the runaway again than she was at beholding him. "I
+didn't know you ran a motor-boat," he added. "I don't," said she
+simply and helplessly. "That's the trouble, it won't run."
+
+"How comes it that you are up here?" went on Tom.
+
+"I am stopping with friends, who have a cottage near the Lakeview
+Hotel. They have a motor-boat and I got Dick Blythe--he's the owner of
+this--to show me how to run it. I thought I knew, and I started out a
+little while ago. At first it went beautifully, but a few minutes ago
+it blew up, or--or something dreadful happened."
+
+"Nothing very dreadful, I guess," Tom assured her. "I think I can fix
+it." He got into the other boat and soon saw what the trouble was.
+The carburetor had gotten out of adjustment and the gasoline was not
+feeding properly. The young inventor soon had it in order, and,
+testing the motor, found that it worked perfectly.
+
+"Oh, I can't thank you enough," cried Miss Nestor with a flash from her
+brown eyes that made Tom's heart beat double time. "I was afraid I had
+damaged the boat, and I knew Dick, who is a sort of second cousin of
+mine, would never forgive me."
+
+"There's no harm done," Tom assured her. "But you had better keep near
+us on your way back, that is, if you are going back."
+
+"Oh, indeed I am. I was frightened when I found I'd come so far away
+from shore, and then, when that explosion took place--well, you can
+imagine how I felt. Indeed I will keep near you. Are you stopping
+near here? If you are, I wish you'd come and see me, you and Mr.
+Newton," she added, for Tom had introduced his chum.
+
+"I'll be very glad to," answered our hero, and he told how he happened
+to be in the neighborhood. "I'll give you a few lessons in managing a
+boat, if you like," he added.
+
+"Oh, will you? That will be lovely! I won't tell Dick about it, and
+I'll surprise him some day by showing him how well I can run his boat."
+
+"Good idea," commented Tom.
+
+He started the motor for Miss Nestor, having stopped it after his first
+test, and then, with the DOT, which was the name of the small boat Miss
+Nestor was in, following the larger ARROW, the run back to the hotel
+was made. The young lady turned off near the Lakeview dock to go to
+the cottage where she was stopping and the lads tied up at the hotel
+boathouse.
+
+"Yes, we are in for a storm," remarked Tom as he and his chum walked up
+toward the hotel. "I wonder how dad is? I hope the outing is doing
+him good."
+
+"There he comes now," observed Ned, and, looking up, Tom saw his father
+approaching. The young inventor was at once struck by the expression
+on his parent's face. Mr. Swift looked worried and Tom anxiously
+hastened forward to meet him.
+
+"What's the matter dad?" he asked as cheerfully as he could. "Have you
+been figuring over that gyroscope problem again, against my express
+orders?" and he laughed a little.
+
+"No, Tom, it's not the gyroscope that's worrying me."
+
+"What is it then?"
+
+"Those scoundrels are around again, Tom!" and Mr. Swift looked
+apprehensively about him.
+
+"You mean the men who stole the turbine model?"
+
+"Yes. I was walking in the woods near the hotel yesterday and I saw
+Anson Morse. He did not see me, for I turned aside as quickly as I had
+a glimpse of him. He was talking to another man."
+
+"What sort of a man?"
+
+"Well, an ordinary enough individual, but I noticed that he had
+tattooed on the little finger of his left hand a blue ring."
+
+"Happy Harry, the tramp!" exclaimed Tom. "What can he and Morse be
+doing here?"
+
+"I don't know, Tom, but I'm worried. I wish I was back home. I'm
+afraid something may happen to some of my inventions. I want to go
+back to Shopton, Tom."
+
+"Nonsense, dad. Don't worry just because you saw some of your former
+enemies. Everything is all right at home. Mrs. Baggert and Garret
+Jackson will look after things. But, if you like, I, can find out for
+you how matters are."
+
+"How, Tom?"
+
+"By taking a run down there in my motor-boat. I can do it to-morrow
+and get back by night, if I start early. Then you will not worry."
+
+"All right, Tom; I wish you would. Come up to my room and we will talk
+it over. I'd rather leave you go than telephone, as I don't like to
+talk of my business over the wire if I can avoid it."
+
+
+
+
+CHAPTER X
+
+A CRY FOR HELP
+
+
+"Now, dad, tell me all about it," requested Tom when he and Ned were in
+Mr. Swift's apartment at the hotel, safe from the rain that was
+falling. "How did you happen to see Anson Morse and Happy Harry?" My
+old readers will doubtless remember that the latter was the disguised
+tramp who was so vindictive toward Tom, while Morse was the man who
+endeavored to sneak in Mr. Swift's shop and steal a valuable invention.
+
+"Well, Tom," proceeded the inventor, "there isn't much to tell. I was
+out walking in the woods yesterday, and when I was behind a clump of
+bushes I heard voices. I looked out and there I saw the two men."
+
+"At first I thought they were trailing me, but I saw that they had not
+seen me, and I didn't see how they could know I was in the
+neighborhood. So I quietly made my way back to the hotel."
+
+"Could you hear what they were saying?"
+
+"Not all, but they seemed angry over something. The man with the blue
+ring on his finger asked the other man whether Murdock had been heard
+from."
+
+"Who is Murdock?"
+
+"I don't know, unless he is another member of the gang or unless that
+is an assumed name."
+
+"It may be that. What else did you hear?"
+
+"The man we know as Morse replied that he hadn't heard from him, but
+that he suspected Murdock was playing a double game. Then the
+tramp--Happy Harry--asked this question: 'Have you any clew to the
+sparkler?' And Morse answered: 'No, but I think Murdock has hid it
+somewhere and is trying to get away with it without giving us our
+share.' Then the two men walked away, and I came back to the hotel,"
+finished Mr. Swift.
+
+"Sparkler," murmured Tom. "I wonder what that can be?"
+
+"That's a slang word for diamonds," suggested Ned.
+
+"So it is. In that case, dad, I think we have nothing to worry about.
+Those fellows must be going to commit a diamond robbery or perhaps it
+has already taken place."
+
+The inventor seemed relieved at this theory of his son. His face
+brightened and he said: "If they are going to commit a robbery, Tom, we
+ought to notify the police."
+
+"But if they said that 'Murdock,' whoever he is, had the sparkler and
+was trying to get away with it without giving them their share,
+wouldn't that indicate that the robbery had already taken place?" asked
+Ned.
+
+"That's so," agreed Tom. "But it won't do any harm to tell the hotel
+detective that suspicious characters are around, no matter if the robbery
+has been committed. Then he can be on the lookout. But I don't think we
+have anything to worry about, dad. Still, if you like, I'll take a run
+down to the house to see that everything is all right, though I'm sure
+it will be found that we have nothing to be alarmed over."
+
+"Well, I will be more relieved if you do," said the inventor, "However,
+suppose we have a good supper now and you boys can stay at the hotel
+to-night. Then you and Ned can start off early in the morning."
+
+"All right," agreed Tom, but there was a thoughtful look on his face
+and he appeared to be planning something that needed careful attention
+to details.
+
+After supper that night Tom took his chum to one side and asked: "Would
+you mind very much if you didn't make the trip to Shopton with me?"
+
+"No, Tom, of course not, if it will help you any. Do you want me to
+stay here?"
+
+"I think it will be a good plan. I don't like to leave dad alone if
+those scoundrels are around. Of course he's able to look after
+himself, but sometimes he gets absent minded from thinking too much
+about his inventions."
+
+"Of course I'll stay here at the hotel. This is just as good a
+vacation as I could wish."
+
+"Oh, I don't mean all the while. Just a day or so--until I come back.
+I may be here again by to-morrow night and find that my father is
+needlessly alarmed. Then something may have happened at home and I
+would be delayed. If I should be, I'd feel better to know that you
+were here."
+
+"Then I'll stay, and if I see any of those men--"
+
+"You'd better steer clear of them," advised Tom quickly. "They are
+dangerous customers."
+
+"All right. Then I'll go over and give Miss Nestor lessons on how to
+run a motor-boat," was the smiling response. "I fancy, with what she
+and I know, we can make out pretty well."
+
+"Hold on there!" cried Tom gaily. "No trespassing, you know."
+
+"Oh, I'll just say I'm your agent," promised Ned with a grin. "You
+can't object to that."
+
+"No, I s'pose not. Well, do the best you can. She is certainly a nice
+girl."
+
+"Yes, but you do seem to turn up at most opportune times. Luck is
+certainly with you where she is concerned. First you save her in a
+runaway--"
+
+"After I start the runaway," interrupted Tom.
+
+"Then you take her for a ride in your motor-boat, and, lastly, you come
+to her relief when she is stalled in the middle of the lake. Oh you
+certainly are a lucky dog!"
+
+"Never mind, I'm giving you a show. Now let's get to bed early, as I
+want to get a good start."
+
+Tom awoke to find a nasty, drizzling rainstorm in progress, and the
+lake was almost hidden from view by a swirling fog. Still he was not
+to be daunted from his trip to Shopton by the weather, and, after a
+substantial breakfast, he bade his father and Ned good-by and started
+off in the ARROW.
+
+The canopy he had provided was an efficient protection against the
+rain, a celluloid window in the forward hanging curtains affording him
+a view so that he could steer.
+
+Through the mist puffed the boat, the motor being throttled down to
+medium speed, for Tom was not as familiar with the lake as he would
+like to have been, and he did not want to run aground or into another
+craft.
+
+He was thinking over what his father had told him about the presence of
+the men and vainly wondering what might be their reference to the
+"sparkler." His thoughts also dwelt on the curious removal of the
+bracing block from under the gasoline tank of his boat.
+
+"I shouldn't be surprised but what Andy Foger did that," he mused.
+"Some day he and I will have a grand fight, and then maybe he'll let me
+alone. Well, I've got other things to think about now. The hotel
+detective can keep a lookout for the men around the hotel, after the
+warning I gave him, and I'll see that all is right at home."
+
+The fog lifted somewhat and Tom put on more speed. As he was steering
+the boat along near shore he heard, off to the woods at his right, the
+report of a gun. It came so suddenly that he jumped involuntarily. A
+moment later there sounded, plainly through the damp air, a cry for
+help.
+
+"Some one's hurt--shot!" cried the youth aloud.
+
+He turned the boat in toward the bank. As he shut off the power from
+the motor he heard the cry again:
+
+"Help! Help! Help!"
+
+"I must go ashore!" he exclaimed. "Probably some one is badly wounded
+by a gun."
+
+He paused for a moment as the fear came to him that it might be some of
+the patent thieves. Then, dismissing that idea as the ARROW's prow
+touched the gravel, Tom sprang out, drew the boat up a little way,
+fastened the rope to a tree and hurried off into the dripping woods in
+the direction of the voice that was calling for aid.
+
+
+
+
+CHAPTER XI
+
+A QUICK RUN
+
+
+"Where are you?" cried Tom. "Are you hurt? Where are you?"
+
+Uttering these words after he had hurried into the woods a short
+distance, the young inventor paused for an answer. At first he could
+hear nothing but the drip of water from the branches of the trees;
+then, as he listened intently, he became aware of a groan not far away.
+
+"Where are you?" cried the lad again. "I've come to help you. Where
+are you?"
+
+He had lost what little fear he had had at first, that it might be one
+of the unscrupulous gang, and came to the conclusion that he might
+safely offer to help.
+
+Once more the groan sounded and it was followed by a faint voice
+speaking:
+
+"Here I am, under the big oak tree. Oh, whoever you are, help me
+quickly! I'm bleeding to death!"
+
+With the sound of the voice to guide him, Tom swung around. The appeal
+had come from the left and, looking in that direction, he saw, through
+the mist, a large oak tree. Leaping over the underbrush toward it he
+caught sight of the wounded man at its foot. Beside him lay a gun and
+there was a wound in the man's right arm.
+
+"Who shot you?" cried Tom, hurrying to the side of the man. "Was it
+some of those patent thieves?" Then, realizing that a stranger would
+know nothing of the men who had stolen the model, Tom prepared to
+change the form of his question. But, before he had an opportunity to
+do this, the man, whose eyes were closed, opened them, and, as he got a
+better sight of his face, Tom uttered a cry.
+
+"Why, it's Mr. Duncan!" exclaimed the lad. He had recognized the rich
+hunter, whom he had first met in the woods that spring shortly after
+Happy Harry, the tramp, had disabled Tom's motor-cycle. "Mr. Duncan,"
+the young inventor repeated, "how did you get shot?"
+
+"Is that you, Tom Swift?" asked the gunner. "Help me, please. I must
+stop this bleeding in my arm. I'll tell you about it afterward. Wind
+something around it tight--your handkerchief will do."
+
+The man sighed weakly and his eyes closed again. The lad saw the blood
+spurting from an ugly wound.
+
+"I must make a tourniquet," the youth exclaimed. "That will check the
+bleeding until I can get him to a doctor."
+
+With Tom to think was to act. He took out his knife and cut off Mr.
+Duncan's sleeves below the injury, slashing through coat and shirts.
+Then he saw that part of a charge of shot had torn away some of the
+large muscular development of the upper arm. The hunter seemed to have
+fainted and the youth worked quickly. Tying his handkerchief above the
+wound and inserting a small stone under the cloth, so that the pebble
+would press on the main artery, Tom put a stick in the handkerchief and
+began to twist it. This had the effect of tightening the linen around
+the arm, and in a few seconds the lad was glad to see that the blood
+had stopped spurting out with every beat of the heart. Giving the
+tourniquet a few more twists to completely stop the flow of blood, Tom
+fastened the stick-lever in place by a bit of string.
+
+"That's--that's better," murmured Mr. Duncan. "Now if you can go for a
+doctor--" He had to pause for breath.
+
+"I'll not leave you here alone while I go for a doctor," declared Tom.
+"I have my motor-boat on the lake. Do you think I could get you down
+to it and take you home?"
+
+"Perhaps--maybe. I'll be stronger in a moment, now that the bleeding
+has stopped. But not--not home--frighten my wife. Take me to the
+sanitarium if you can--sanitarium up the lake, a few miles from here."
+
+The unfortunate man, who had tried to sit upright, had to lean back
+against the tree again. Tom understood what he meant in spite of the
+broken sentences. Mr. Duncan did not want to be taken home in the
+condition he was then in, for fear of alarming his wife. He wanted to
+be taken to the sanitarium, and Tom knew where this was, a well-known
+resort for the treatment of various diseases and surgical cases. It
+was about five miles away and on the opposite shore of the lake.
+
+"Water--a drink!" murmured Mr. Duncan.
+
+Seeing that his patient would be all right, for a few minutes at least,
+Tom hurried to his motor-boat, got a cup and, filling it with water
+from a jug he carried, he hastened with it to the hunter. The fluid
+revived the man wonderfully and now that the bleeding had almost
+completely stopped, Mr. Duncan was much stronger.
+
+"Do you think you can get to the boat, if I help you?" asked Tom.
+
+"Yes, I believe so. To think of meeting you again, and under such
+circumstances! It is providential."
+
+"Did someone shoot you?" inquired Tom, who could not get out of his
+head the notion of the men who had once assaulted him.
+
+"No, I shot myself," answered Mr. Duncan as he got to his feet with
+Tom's help. "I was out with my gun, practicing just as I was that day
+when I met you in the woods. I stooped down to crawl under a bush and
+the weapon went off, the muzzle being close against my arm. I can't
+understand how it happened. I fell down and called for help. Then I
+guess I must have fainted, but I came to when I heard you talking to
+me. I shouldn't have come out to-day as it is so wet, but I had some
+new shot shells I wished to try in order to test them before the
+hunting season. But if I can get to the sanitarium, I will be well
+taken care of. I know one of the doctors there."
+
+With Tom leading him and acting as a sort of support, the journey to
+the motor-boat was slowly made. Making as comfortable a bed as
+possible out of the seat cushions, Tom assisted Mr. Duncan to it, and
+then starting the engine he sent his boat out from shore at half speed,
+as the fog was still thick and he did not want to run upon a rock.
+
+"Do you know where the sanitarium is?" asked the wounded hunter.
+
+"About," answered Tom a little doubtfully, "but I'm afraid it's going
+to be hard to locate it in this fog."
+
+"There's a compass in my coat pocket," said Mr. Duncan. "Take it out
+and I'll tell you how to steer. You ought to carry a compass if you're
+going to be a sailor."
+
+Tom was beginning to think so himself and wondered that he had not
+thought of it before. He found the one the hunter had, and placing it
+on the seat near him, he carefully listened to the wounded man's
+directions. Tom easily comprehended and soon had the boat headed in
+the proper direction. After that it was comparatively easy to keep on
+the right course, even in the fog.
+
+But there was another danger, however, and this was that he might run
+into another boat. True, there were not many on Lake Carlopa, but
+there were some, and one of the few motor-boats might be out in spite
+of the bad weather.
+
+"Guess I'll not run at full speed," decided Tom. "I wouldn't like to
+crash into the RED STREAK. We'd both sink."
+
+So he did not run his motor at the limit and sat at the steering-wheel,
+peering ahead into the fog for the first sight of another craft.
+
+He turned to look at Mr. Duncan and was alarmed at the pallor of his
+face. The man's eyes were closed and he was breathing in a peculiar
+manner.
+
+"Mr. Duncan," cried Tom, "are you worse?"
+
+There was no answer. Leaving the helm for a moment, Tom bent over the
+injured hunter. A glance showed him what had happened. The tourniquet
+had slipped and the wound was bleeding again. Tom quickly shut off the
+motor, so that he might give his whole attention to the work of
+tightening the handkerchief. But something seemed to be wrong. No
+matter how tightly he twisted the stick the blood did not stop flowing.
+The lad was frightened. In a short time the man would bleed to death.
+
+"I've got to get him to the sanitarium in record time!" exclaimed Tom.
+"Fog or no fog, I've got to run at full speed! I've got to chance it!"
+
+Making the bandage as tight as he could and fastening it in place, the
+young inventor sprang to the motor and set it in motion. Then he went
+to the wheel. In a few minutes the ARROW was speeding through the
+water as it had never done before, except when it had raced the RED
+STREAK. "If I hit anything--good-by!" thought Tom grimly. His hands
+were tense on the rim of the steering-wheel and he was ready in an
+instant to reverse the motor as he sat there straining his eyes to see
+through the curtain of mist that hung over the lake. Now and then he
+glanced at the compass, to keep on the right course, and from time to
+time he looked at Mr. Duncan. The hunter was still unconscious.
+
+How Tom accomplished that trip he hardly remembered afterward. Through
+the fog he shot, expecting any moment to crash into some other boat.
+He did pass a rowing craft in which sat a lone fisherman. The lad was
+upon him in an instant, but a turn of the wheel sent the ARROW safely
+past, and the startled fisherman, whose frail craft was set to rocking
+violently by the swell from the motor-boat, sent an objecting cry
+through the fog after Tom. But the youth did not reply. On and on he
+raced, getting the last atom of power from his motor.
+
+He feared Mr. Duncan would be dead when he arrived, but when he saw the
+dock of the sanitarium looming up out of the mist and shut off the
+power to slowly run up to it, he placed his hand on the wounded man's
+heart and found it still beating.
+
+"He's alive, anyhow," thought the youth, and then his craft bumped up
+against the bulkhead and a man in the boathouse on the dock was sent on
+the run for a physician.
+
+Mr. Duncan was quickly taken up to the sanitarium on a stretcher and
+Tom followed.
+
+"You must have made a record run," observed one of the physicians a
+little while afterward, when Tom was telling of his trip while waiting
+in the office to hear the report on the hunter's condition.
+
+"I guess I did," muttered the young inventor "only I didn't think so at
+the time. It seemed as if we were only crawling along."
+
+
+
+
+CHAPTER XII
+
+SUSPICIOUS CHARACTERS
+
+
+Under the skill of the physicians at the lake sanitarium Mr. Duncan's
+wound was quickly attended to and the bleeding, which Tom had partly
+checked, was completely stopped. Some medicines having been
+administered, the hunter regained a little of his strength, and, about
+an hour after he had been brought to the resort, he was able to see
+Tom, who, at his request, was admitted to his room. The young inventor
+found Mr. Duncan propped up in bed, with his injured arm bandaged.
+
+"Is the injury a bad one?" asked Tom, entering softly.
+
+"Not as bad as I feared," replied the hunter, while a trained nurse
+placed a chair for the lad at the bedside. "If it had not been for
+you, though, I'm afraid to think of what might have happened."
+
+"I am glad I chanced to be going past when you called," replied the lad.
+
+"Well, you can imagine how thankful I am," resumed Mr. Duncan. "I'll
+thank you more properly at another time. I hope I didn't delay you on
+your trip."
+
+"It's not of much consequence," responded the youth. "I was only going
+to see that everything was all right at our house," and he explained
+about his father being at the hotel and mentioned his worriment. "I
+will go on now unless I can do something more for you," resumed Tom.
+"I will probably stay at our house all night to-night instead of trying
+to get back to Sandport."
+
+"I'd like to send word to my wife about what has happened," said the
+hunter. "If it would not be too much out of your way, I'd appreciate
+it if you could stop at my home in Waterford and tell her, so she will
+not be alarmed at my absence."
+
+"I'll do it," replied our hero. "There is no special need of my
+hurrying. I have brought your gun and compass up from the boat. They
+are down in the office."
+
+"Will you do me a favor?" asked Mr. Duncan quickly.
+
+"Of course."
+
+"Then please accept that gun and compass with my compliments. They are
+both of excellent make, and I don't think I shall use that gun this
+season. My wife would be superstitious about it. As for the compass,
+you'll need one in this fog, and I can recommend mine as being
+accurate."
+
+"Oh, I couldn't think of taking them," expostulated Tom, but his eyes
+sparkled in anticipation, for he had been wishing for a gun such as Mr.
+Duncan owned. He also needed a compass.
+
+"If you don't take them I shall feel very much offended," the hunter
+said, "and the nurse here will tell you that sick persons ought to be
+humored. Hadn't they?" and he appealed to the pretty young woman, who
+was smiling at Tom.
+
+"That's perfectly true," she said, showing her white, even teeth. "I
+think, Mr. Swift, I shall have to order you to take them."
+
+"All right," agreed Tom, "only it's too much for what I did."
+
+"It isn't half enough," remarked Mr. Duncan solemnly. "Just explain
+matters to my wife, if you will, and tell her the doctor says I can be
+out in about a week. But I'm not going hunting or practicing shots
+again."
+
+A little later Tom, with the compass before him to guide him on his
+course through the fog, was speeding his boat toward Waterford. Now
+and then he glanced at the fine shotgun which he had so unexpectedly
+acquired.
+
+"This will come in handy this fall!" he exclaimed. "I'll go hunting
+quail and partridge as well as wild ducks. This compass is just what I
+need, too."
+
+Mrs. Duncan was at first very much alarmed when Tom started to tell her
+of the accident, but she soon calmed down as the lad went more into
+details and stated how comparatively out of danger her husband now was.
+The hunter's wife insisted that Tom remain to dinner, and as he had
+made up his mind he would have to devote two days instead of one to the
+trip to his house, he consented.
+
+The fog lifted that afternoon, and Tom, rejoicing in the sunlight,
+which drove away the storm clouds, speeded up the ARROW until she was
+skimming over the lake like a shaft from a bow.
+
+"This is something like," he exclaimed. "I'll soon be at home, find
+everything all right and telephone to dad. Then I'll sleep in my own
+room and start back in the morning."
+
+When Tom was within a few miles of his own boathouse he heard behind
+him the "put-put" of a motor craft. Turning, he saw the RED STREAK
+fairly flying along at some distance from him.
+
+"Andy certainly is getting the speed out of her now," he remarked.
+"He'd beat me if we were racing, but the trouble with his boat and
+engine is that he can't always depend on it. I guess he doesn't
+understand how to run it. I wonder if he'll offer to race now?"
+
+But the red-haired owner of the auto boat evidently did not intend to
+offer Tom a race. The RED STREAK went on down the lake, passing the
+ARROW about half a mile away. Then the young inventor saw that Andy
+had two other lads in the boat with him.
+
+"Sam Snedecker and Pete Bailey, I guess," he murmured. "Well, they're
+a trio pretty much alike. The farther off they are the better I like
+it."
+
+Tom once more gave his attention to his own boat. He was going at a
+fair speed, but not the limit, and he counted on reaching home in about
+a half hour. Suddenly, when he was just congratulating himself on the
+smooth-running qualities of his motor, which had not missed an
+explosion, the machinery stopped.
+
+"Hello!" exclaimed the young inventor in some alarm. "What's up now?"
+
+He quickly shut off the gasoline and went back to the motor. Now there
+are so many things that may happen to a gasoline engine that it would
+be difficult to name them all offhand, and Tom, who had not had very
+much experience, was at a loss to find what had stopped his machinery.
+He tried the spark and found that by touching the wire to the top of
+the cylinder, when the proper connection was, made, that he had a hot,
+"fat one." The compression seemed all right and the supply pipe from
+the gasoline tank was in perfect order. Still the motor would not go.
+No explosion resulted when he turned the flywheel over, not even when
+he primed the cylinder by putting a little gasoline in through the
+cocks on the cylinder heads.
+
+"That's funny," he remarked to himself as he rested from his labors and
+contemplated the "dead" motor. "First time it has gone back on me."
+The boat was drifting down the lake, and, at the sound of another motor
+craft approaching, Tom looked up. He saw the RED STREAK, containing
+Andy Foger and his cronies. They had observed the young inventor's
+plight.
+
+"Want a tow?" sneered Andy.
+
+"What'll you take for your second-hand boat that won't run?" asked Pete
+Bailey.
+
+"Better get out of the way or you might be run down," added Sam
+Snedecker.
+
+Tom was too angry and chagrined to reply, and the RED STREAK swept on.
+
+"I'll make her go, if it takes all night!" declared Tom energetically.
+Once more he tried to start the motor. It coughed and sighed, as if in
+protest, but would not explode. Then Tom cried: "The spark plug!
+That's where the trouble is, I'll wager. Why didn't I think of it
+before?"
+
+It was the work of but a minute to unscrew the spark plugs from the
+tops of the cylinders. He found that both had such accumulations of
+carbon on them that no spark could ever have reached the mixture of
+gasoline and air.
+
+"I'll put new ones in," he decided, for he carried a few spare plugs
+for emergencies. Inside of five minutes, with the new plugs in place,
+the motor was running better than before.
+
+"Now for home!" cried Tom, "and if I meet Andy Foger I'll race him
+this time."
+
+But the RED STREAK was not in sight, and, a little later, Tom had run
+the ARROW into the boathouse, locked the door and was on his way up to
+the mansion.
+
+"I suppose Mrs. Baggert and Garret will be surprised to see me," he
+remarked. "Maybe they'll think we don't trust them, by coming back in
+this fashion to see that everything is safe. But then, I suppose, dad
+is naturally nervous about some of his valuable machinery and
+inventions. I think I'll find everything all right, though."
+
+As Tom went up the main path and swung off to a side one, which was a
+short cut to the house, he saw in the dusk, for it was now early
+evening, a movement in the bushes that lined the walk.
+
+"Hello, Garret!" exclaimed the lad, taking it for granted it was the
+engineer employed by Mr. Swift.
+
+There was no reply, and Tom, with a sudden suspicion, sprang toward the
+bushes. The shrubbery was more violently agitated and, as the lad
+reached the screen of foliage, he saw a man spring up from the ground
+and take to his heels.
+
+"Here! Who are you? What do you want?" yelled Tom.
+
+Hardly had he spoken when from behind a big apple tree another man
+sprung. It was light enough so that the lad could see his face, and a
+glimpse of it caused him to cry out:
+
+"Happy Harry, the tramp!"
+
+Before he could call again the two men had disappeared.
+
+
+
+
+CHAPTER XIII
+
+TOM IN DANGER
+
+
+"Garret! Garret Jackson!" cried Tom as he struggled through the hedge
+of bushes and ran after the men. "Where are you, Garret? Come on and
+help me chase these men!"
+
+But there came no answer to Tom's hail. He could not hear the sound of
+the retreating footsteps of the men now and concluded that they had
+made their escape. Still he would not give up, but dashed on, slipping
+and stumbling, now and then colliding with a tree.
+
+"What can they be doing here?" thought Tom in great anxiety. "Are they
+after some more of dad's inventions because they didn't get his turbine
+motor?"
+
+"Hello! Who's there? Who are you?" called a voice suddenly.
+
+"Oh, Garret! Where have you been?" asked the young inventor,
+recognizing the tones of his father's keeper. "I've been calling you.
+Some of those scoundrels are around again!"
+
+"Why if it isn't Tom!" ejaculated the engineer. "However in the world
+did you get here? I thought you were at Sandport."
+
+"I'll explain later, Garret. Just now I want to catch those men, if I
+can."
+
+"Which men?"
+
+"Happy Harry and another one. I saw them hiding down by the orchard
+path. Come on, they're right ahead of us."
+
+But though they hunted as well as they were able to in the
+fast-gathering darkness, there was no trace of the intruders. They had
+to give up, and Tom, after going to the boathouse to see that the ARROW
+was all right, returned to the house, where he told the engineer and
+housekeeper what had brought him back and how he had surprised the two
+men.
+
+"Is everything all right, Garret?" he concluded. "Dad is nervous and
+frightened. I must telephone him at the hotel to-night and let him
+know, for I promised to come back. I can't, though, until to-morrow."
+
+"Everything is all right as far as I know," answered Jackson. "I've
+kept a careful watch and the burglar alarm has been in working order.
+Mrs. Baggert and I haven't been disturbed a single night since you went
+away. It's curious that the men should be here the very night you come
+back. Maybe they followed you."
+
+"I hardly think so, for they didn't know I was coming."
+
+"You can't tell what those fellows know," commented the engineer.
+"But, anyhow, I don't suppose they could have gotten here from Sandport
+as soon as you did."
+
+"Oh, yes they could, in their automobile," declared Tom. "But I don't
+believe they knew I was coming. They knew we were away, however, and
+thought it would be a good time to steal something, I guess. Are you
+sure nothing has been taken?"
+
+"Perfectly sure, but you and I will take a look around the shop."
+
+They made a hasty examination, but found nothing disturbed and no signs
+that anyone had tried to break in.
+
+"I think I'll telephone dad that everything is all right," decided Tom.
+"It is as far as his inventions are concerned, and if I tell about
+seeing the men it will only worry him. I can explain that part better
+when I see him. But when I go back, Garret, you will have to be on
+your guard, since those men are in the neighborhood."
+
+"I will, Tom. Don't worry."
+
+Mr. Swift was soon informed by his son over the telephone that nothing
+in the shops had been disturbed, and the inventor received the news
+with evident satisfaction. He requested Tom to come back to the hotel
+in the morning, in order that the three of them might go for a ride
+about the lake in the afternoon, and Tom decided to make an early start.
+
+The night passed without incident, though Tom, who kept the gun Mr.
+Duncan had given him in readiness for use, got up several times,
+thinking he heard suspicious noises. After an early breakfast, and
+having once more cautioned the engineer and housekeeper to be on their
+guard, Tom started back in the ARROW.
+
+As it would not be much out of his way, the young inventor decided to
+cut across the lake and stop at the sanitarium, that he might inquire
+about Mr. Duncan. He thought he could speed the ARROW up sufficiently
+to make up for any time he might lose, and, with this in mind, he
+headed out toward the middle of Lake Carlopa. The engine was working
+splendidly with the new spark plugs, and Tom was wondering if there was
+any possible method of getting more revolutions out of the motor. He
+had about come to the conclusion that a new propeller might answer his
+purpose when he heard the noise of an approaching boat. He looked up
+quickly and exclaimed:
+
+"Andy Foger again, and Pete and Sam are with him. It's a wonder he
+wouldn't go off on a trip instead of cruising around so near home.
+Guess he's afraid he'll get stuck."
+
+Idly Tom watched the RED STREAK. It was cutting through the water at a
+fast rate, throwing up curling foam on either side of the sharp bow.
+"He seems to be heading this way," mused Tom. "Well, I'm not going to
+race with him to-day."
+
+Nearer and nearer came the speedy craft, straight for the ARROW. The
+young inventor shifted his helm in order to get out of Andy's course,
+but to his surprise he saw that the red haired lad changed the
+direction of his own boat.
+
+"Guess he wants to see how close he can come to me," thought our hero.
+"Maybe he wants to show how fast he's going."
+
+The RED STREAK was now so close that the features of the occupants
+could easily be distinguished. There were grins on the faces of Andy
+and his cronies.
+
+"Get out of the way or we'll run you down!" cried the bully. "We've
+got the right of way."
+
+"Don't you try anything like that!" shouted Tom in some alarm, not that
+he was afraid of Andy, but the RED STREAK was getting dangerously near,
+and he knew Andy was not a skillful helmsman. The auto-boat was now
+headed directly at the ARROW and coming on speedily. Andy was bending
+over the wheel and Tom had begun to turn his, in order to get well out
+of the way of the insolent, squint-eyed lad and his friends.
+
+Suddenly Andy uttered a cry and leaped up.
+
+"Look out! Look out!" he yelled. "My steering gear has broken! I
+can't change my course. Look out!"
+
+The RED STREAK was bearing right down on Tom's boat.
+
+"Shut off your power! Reverse!" shouted Tom.
+
+Andy seemed confused and did not know what to do. Sam Snedecker sprang
+to the side of his crony, but he knew even less about a motor-boat. It
+looked as if Tom would be run down, and he was in great danger.
+
+But the young inventor did not lose his head. He put his wheel hard
+over and then, leaping to his motor, sent it full speed forward. Not a
+moment too soon had he acted, for an instant later the other boat shot
+past the stern of the ARROW, hitting it a severe but glancing blow.
+Tom's boat quivered from end to end and he quickly shut off the power.
+By this time Andy had succeeded in slowing down his craft. The young
+inventor hastily looked over the side of the ARROW. One of the rudder
+fastenings had been torn loose.
+
+"What do you mean by running me down?" shouted Tom angrily.
+
+"I--I didn't do it on purpose," returned Andy contritely. "I was
+seeing how near I could come to you when my steering gear broke. I
+hope I haven't damaged you."
+
+"My rudder's broken," went on Tom "and I've got to put back to repair
+it. I ought to have you arrested for this!"
+
+"I'll pay for the damage," replied Andy, and he was so frightened that
+he was white, in spite of his tan and freckles.
+
+"That won't do me any good now," retorted Tom. "It will delay me a
+couple of hours. If you try any tricks like that again, I'll complain
+to the authorities and you won't be allowed to run a boat on this lake."
+
+Andy knew that his rival was in the right and did not reply. The bully
+and his cronies busied themselves over the broken steering gear, and
+the young inventor, finding that he could make a shift to get back to
+his boathouse, turned his craft around and headed for there, in order
+to repair the damage.
+
+
+
+
+CHAPTER XIV
+
+THE ARROW DISAPPEARS
+
+
+Paying no heed to the occupants of the bully's boat, who, by reason of
+their daring, had been responsible for his accident that might have
+resulted seriously, Tom was soon at his dock. He had it conveniently
+arranged for hoisting craft out of the water to repair them, and in a
+few minutes the stern of the ARROW was elevated so that he could get at
+the rudder.
+
+"Well, it's not as bad as I thought," he remarked when, with critical
+eye, he had noted the damage done. "I can fix it in about an hour if
+Garret helps me."
+
+Going up to the house to get some tools and to tell the engineer that
+he had returned, Tom looked out over the lake and saw Andy's boat
+moving slowly off.
+
+"They've got her fixed up in some kind of shape," he murmured. "It's a
+shame for a chump like Andy to have a good boat like that. He'll spoil
+it in one season. He's getting altogether too reckless. First thing
+he knows, he and I will have a clash and I'll pay back some of the old
+scores."
+
+Mr. Jackson was much surprised to see the young inventor home again so
+soon, as was also Mrs. Baggert. Tom explained what had happened, and
+he and the engineer went to work repairing the damage done by the RED
+STREAK. As the owner of the ARROW had anticipated, the work did not
+take long, and, shortly before dinner time, the boat was ready to
+resume the interrupted trip to Sandport.
+
+"Better stay and have lunch," urged Mrs. Baggert. "You can hardly get
+to the hotel by night, anyhow, and maybe it would be better not to
+start until to-morrow."
+
+"No, I must get back to-night or dad would be worried," declared Tom.
+"I've been gone longer now than I calculated on. But I will have
+dinner here, and, if necessary, I can do the last half of the trip
+after dark. I know the way now and I have a compass and a good
+searchlight."
+
+The ARROW was let down into the water again and tied outside the
+boathouse ready for a quick start. The dinner Mrs. Baggert provided
+was so good that Tom lingered over it longer than he meant to, and he
+asked for a second apple dumpling with hard sauce on. So it was with a
+very comfortable feeling indeed and with an almost forgiving spirit
+toward Andy Foger that our hero started down the path to the lake.
+
+"Now for a quick run to Sandport," he said aloud. "I hope I shan't see
+any more of those men and that dad hasn't been bothered by them. His
+suspicions about the house weren't altogether unfounded, for I did see
+the tramp and some one else sneaking around, but I don't believe
+they'll come back now."
+
+Tom swung around the path that led to the dock. As he came in sight of
+the water, he stared as if he could not believe what he saw, or,
+rather, what he did not see. For there was no craft tied to the
+string-piece, where he had fastened his motor-boat. He looked again,
+rubbed his eyes to make sure and then cried out:
+
+"The ARROW is gone!"
+
+There was no doubt of it. The craft was not at the dock. Breaking
+into a run, Tom hastened to the boathouse. The ARROW was not in there,
+and a look across the lake showed only a few rowboats in sight.
+
+"That's mighty funny," mused the youth. "I wonder--"
+
+He paused suddenly in his thoughts.
+
+"Maybe Garret took it out to try and see that it worked all right," he
+said hopefully. "He knows how to run a boat. Maybe he wanted to see
+how the rudder behaved and is out in it now. He got through dinner
+before I did. But I should have thought he'd have said something to me
+if he was going out in it."
+
+This was the one weak point in Tom's theory, and he felt it at once.
+
+"I'll see if Garret is in his shop," he went on as he turned back
+toward the house.
+
+The first person he met as he headed for the group of small structures
+where Mr. Swift's inventive work was carried on was Garret Jackson, the
+engineer.
+
+"I--I thought you were out in my boat!" stammered Tom.
+
+"Your boat! Why would I be out in your boat?" and Mr. Jackson removed
+his pipe from his mouth and stared at the young inventor.
+
+"Because it's gone!"
+
+"Gone!" repeated the engineer, and then Tom told him. The two hurried
+down to the dock, but the addition of another pair of eyes was of no
+assistance in locating the ARROW. The trim little motor craft was
+nowhere to be seen.
+
+"I can't understand it," said Tom helplessly. "I wasn't gone more than
+an hour at dinner, and yet--"
+
+"It doesn't take long to steal a motor-boat," commented the engineer.
+
+"But I think I would have heard them start it," went on the lad.
+"Maybe it drifted off, though I'm sure I tied it securely."
+
+"No, there's not much likelihood of that. There's no wind to-day and
+no currents in the lake. But it could easily have been towed off by
+some one in a rowboat and then you would not have heard the motor
+start."
+
+"That's so," agreed the youth. "That's probably how they did it. They
+sneaked up here in a rowboat and towed the ARROW off. I'm sure of it."
+
+"And I'll wager I know who did it," exclaimed Mr. Jackson energetically.
+
+"Who?" demanded Tom quickly.
+
+"Those men who were sneaking around--Happy Harry and his gang. They
+stole the boat once and they'd do it again. Those men took your boat,
+Tom."
+
+The young inventor shook his head.
+
+"No," he answered, "I don't believe they did."
+
+"Why not?"
+
+"Well, because they wouldn't dare come back here when they knew we're
+on the lookout for them. It would be too risky."
+
+"Oh, those fellows don't care for risk," was the opinion of Mr.
+Jackson. "Take my word for it, they have your boat. They have been
+keeping watch, and as soon as they saw the dock unprotected they
+sneaked up and stole the ARROW."
+
+"I don't think so," repeated Mr. Swift's son.
+
+"Who do you think took it then?"
+
+"Andy Foger!" was the quick response. "I believe he and his cronies
+did it to annoy me. They have been trying to get even with me-or at
+least Andy has--for outbidding him on this boat. He's tried several
+times, but he hasn't succeeded--until now. I'm sure Andy Foger has my
+boat," and Tom, with a grim tightening of his lips, swung around as
+though to start in instant pursuit.
+
+"Where are you going?" asked Mr. Jackson.
+
+"To find Andy and his cronies. When I locate them I'll make them tell
+me where my boat is."
+
+"Hadn't you better send some word to your father? You can hardly get
+to Sandport now, and he'll be worried about you."
+
+"That's so, I will. I'll telephone dad that the boat--no, I'll not do
+that either, for he'd only worry and maybe get sick. I'll just tell
+him I've had a little accident, that Andy ran into me and that I can't
+come back to the hotel for a day or two. Maybe I'll be lucky to find
+my boat in that time. But dad won't worry then, and, when I see him, I
+can explain. That's what I'll do," and Tom was soon talking to Mr.
+Swift by telephone.
+
+The inventor was very sorry his son could not come back to rejoin him
+and Ned, but there was no help for it, and, with as cheerful voice as
+he could assume, the lad promised to start for Sandport at the earliest
+opportunity.
+
+"Now to find Andy and my boat!" Tom exclaimed as he hung up the
+telephone receiver.
+
+
+
+
+CHAPTER XV
+
+A DISMAYING STATEMENT
+
+
+Trouble is sometimes good in a way; it makes a person resourceful. Tom
+Swift had had his share of annoyances of late, but they had served a
+purpose. He had learned to think clearly and quickly. Now, when he
+found his boat stolen, he at once began to map out a plan of action.
+
+"What will you do first?" asked Mr. Jackson as he saw his employer's
+son hesitating.
+
+"First I'm going to Andy Foger's house," declared the young inventor.
+"If he's home I'm going to tell him what I think of him. If he's not,
+I'm going to find him."
+
+"Why don't you take your sailboat and run down to his dock?" suggested
+the engineer. "It isn't as quick as your motor-boat, but it's better
+than walking."
+
+"So it is," exclaimed the lad. "I will use my catboat. I had
+forgotten all about it of late. I'm glad you spoke."
+
+He was soon sailing down the lake in the direction of the boathouse on
+the waterfront of Mr. Foger's property. It needed but a glance around
+the dock to show him that the RED STREAK was not there, but Tom
+recollected the accident to the steering gear and thought perhaps Andy
+had taken his boat to some wharf where there was a repair shop and
+there left it to return home himself. But inquiry of Mrs. Foger, who
+was as nice a woman as her son was a mean lad, gave Tom the information
+that his enemy was not at home.
+
+"He telephoned to me that his boat was damaged," said Mrs. Foger
+gently, "and that he had taken it to get fixed. Then, he said, he and
+some friends were going on a little cruise and might not be back
+to-night."
+
+"Did he say where he was going?" asked our hero, who did not tell
+Andy's mother why he wanted to see her son.
+
+"No, and I'm worried about him. Sometimes I think Andy is too--well,
+too impetuous, and I'm afraid he will get into trouble."
+
+Tom, in spite of his trouble, could hardly forbear smiling. Andy's
+mother was totally unaware of the mean traits of her son and thought
+him a very fine chap. Tom was not going to undeceive her.
+
+"I'm afraid something will happen to him," she went on. "Do you think
+there is any danger being out on the lake in a motor-boat, Mr. Swift?
+I understand you have one."
+
+"Yes, I have one," answered Tom. He was going to say he had once had
+one, but thought better of it. "No, there is very little danger this
+time of year," he added.
+
+"I am very glad to hear you say so," went on Mrs. Foger with a sigh.
+"I shall feel more at ease when Andy is away now. When he returns
+home, I shall tell him you called upon him and he will return your
+visit. I am glad to see that the custom of paying calls has not died
+out among the present generation. It is a pleasant habit, and I am
+glad to have my son conform to it. He shall return your kind visit."
+
+"Oh, no, it's of no consequence," replied Tom quickly, thinking grimly
+that his visit was far from a friendly one. "There is no need to tell
+your son I was here. I will probably see him in a day or two.
+
+"Oh, but I shall tell him," insisted Mrs. Foger with a kind smile.
+"I'm sure he will appreciate your call."
+
+There was much doubt concerning this in the mind of the young inventor,
+but he did not express it and soon took his leave. Up and down the
+lake for the rest of the day he cruised, looking in vain for a sight of
+Andy Foger in the RED STREAK, but the racing boat appeared to be well
+hidden.
+
+"If I only could find where they've taken mine," mused Tom. "Hang it
+all, this is rotten luck!" and for the first time he began to feel
+discouraged.
+
+"Maybe you'd better notify the police," suggested Mr. Jackson when Tom
+returned to the Swift house that night. "They might help locate it."
+
+"I think I can do as well as the police," answered the youth. "If the
+boat is anywhere it's on the lake, and the police have no craft in
+which to make a search."
+
+"That's so," agreed the engineer. "I wish I could help you, but I
+don't believe it would be wise for me to leave the house, especially
+since those men have been about lately."
+
+"No, you must stay here," was Tom's opinion. "I'll take another day or
+two to search. By this time Andy and his gang will return, I'm sure,
+and I can tackle them."
+
+"Suppose they don't?"
+
+"Well, then I'll make a tour of the lake in my sailboat and I'll run up
+to Sandport and tell dad, for he will wonder what's keeping me. I'll
+know better next time than to leave my boat at the dock without taking
+out the connection at the spark coil, so no one can start the motor. I
+should have done that at first, but you always think of those things
+afterward."
+
+The lad began his search again the next morning and cruised about in
+little bays and gulfs looking for a sight of the RED STREAK or the
+ARROW, but he saw neither, and a call at Andy's house showed that the
+red-haired youth had not returned. Mrs. Foger was quite nervous over
+her son's continued absence, but Mr. Foger thought it was all right.
+
+Another day passed without any results and the young inventor was
+getting so nervous, partly with worrying over the loss of his boat and
+partly on his father's account, that he did not know what to do.
+
+"I can't stand it any longer," he announced to Mrs. Baggert the night
+of the third day, after a telephone message had been received from Mr.
+Swift. The inventor wanted to know why his son did not return to the
+hotel to join him and Ned. "Well, what will you do?" asked the
+housekeeper.
+
+"If I don't find my boat to-morrow, I'll sail to Sandport, bring home
+dad and Ned and we three will go all over the lake. My boat must be on
+it somewhere, but Lake Carlopa is so cut up that it could easily be
+hidden."
+
+"It's queer that the Foger boy doesn't come home. That makes it look
+as if he was guilty."
+
+"Oh, I'm sure he took it all right," returned Tom. "All I want is to
+see him. It certainly is queer that he stays away as long as he does.
+Sam Snedecker and Pete Bailey are with him, too. But they'll have to
+return some time."
+
+Tom dreamed that night of finding his boat and that it was a wreck. He
+awoke, glad to find that the latter part was not true, but wishing that
+some of his night vision might come to pass during the day.
+
+He started out right after breakfast, and, as usual, headed for the
+Foger home. He almost disliked to ask Mrs. Foger if her son had yet
+returned, for Andy's mother was so polite and so anxious to know
+whether any danger threatened that Tom hardly knew how to answer her.
+But he was saved that embarrassment on this occasion, for as he was
+going up the walk from the lake to the residence he met the gardener
+and from him learned that Andy had not yet come back.
+
+"But his mother had a message from him, I did hear," went on the man.
+"He's on his way. It seems he had some trouble."
+
+"Trouble. What kind of trouble?" asked Tom.
+
+"I don't rightly know, sir, but," and here the gardener winked his eye,
+"Master Andy isn't particular what kind of trouble he gets into."
+
+"That's right," agreed our hero, and as he went down again to where he
+had left his boat he thought: "Nor what kind of trouble he gets other
+people into. I wish I had hold of him for about five minutes!"
+
+The sailboat swung slowly from the dock and heeled over to the gentle
+breeze. Hardly knowing what to do, Tom headed for the middle of the
+lake. He was discouraged and tired of making plans only to have them
+fail.
+
+As he looked across the stretch of water he saw a boat coming toward
+him. He shaded his eyes with his hand to see better, and then, with a
+pair of marine glasses, took an observation. He uttered an exclamation.
+
+"That's the RED STREAK as sure as I'm alive!" he cried. "But what's
+the matter with her? They're rowing!"
+
+The lad headed his boat toward the approaching one. There was no doubt
+about it. It was Andy Foger's craft, but it was not speeding forward
+under the power of the motor. Slowly and laborious the occupants were
+pulling it along, and as it was not meant to be rowed, progress was
+very slow.
+
+"They've had a breakdown," thought Tom. "Serves 'em right! Now wait
+till I tackle 'em and find out where my boat is. I've a good notion to
+have Andy Foger arrested!"
+
+The sailing craft swiftly approached the motor-boat. Tom could see the
+three occupants looking at him, apprehensively as well as curiously, he
+thought.
+
+"Guess they didn't think I'd keep after 'em," mused the young inventor,
+and a little later he was beside the RED STREAK.
+
+"Well," cried Tom angrily, "it's about time you came back!"
+
+"We've had a breakdown," remarked Andy, and he seemed quite humiliated.
+He was beginning to find out that he didn't know as much about a
+motor-boat as he thought he did.
+
+"I've been waiting for you," went on Tom.
+
+"Waiting for us? What for?" asked Sam Snedecker.
+
+"What for? As if you didn't know!" blurted out the owner of the ARROW.
+"I want my boat, Andy Foger, the one you stole from me and hid! Tell
+me where it is at once or I'll have you arrested!"
+
+"Your boat!" repeated the bully, and there was no mistaking the
+surprise in his tones.
+
+"Yes, my boat! Don't try to bluff me like that."
+
+"I'm not trying to bluff you. We've been away, three days and just got
+back."
+
+"Yes, I know you have. You took my boat with you, too."
+
+"Are you crazy?" demanded Pete Bailey.
+
+"No, but you fellows must have been to think you could take my boat and
+me not know it," and Tom, filled with wrath, grasped the gunwale of the
+RED STREAK as if he feared it would suddenly shoot away.
+
+"Look here!" burst out Andy, and he spoke sincerely, "we didn't touch
+your boat. Did we, fellows?"
+
+"No!" exclaimed Sam and Pete at once, and they were very much in
+earnest.
+
+"We didn't even know it was stolen, did we?" went on Andy.
+
+"No," agreed his chums. Tom looked unconvinced.
+
+"We haven't taken your boat and we can prove it," continued the bully.
+"I know you and I have had quarrels, but I'm telling you the truth, Tom
+Swift. I never touched your boat."
+
+There was no mistaking the sincerity of Andy. He was not a skilful
+deceiver, and Tom, looking into his squint-eyes, which were opened
+unusually wide, could not but help believing the fellow.
+
+"We haven't seen it since the day we had the collision," added Andy,
+and his chums confirmed this statement.
+
+"We went off on a little cruise," continued the red-haired bully, "and
+broke down several times. We had bad luck. Just as we were nearing
+home something went wrong with the engine again. I never saw such a
+poor motor. But we never took your boat, Tom Swift, and we can prove
+it."
+
+Tom was in despair. He had been so sure that Andy was the thief, that
+to believe otherwise was difficult. Yet he felt that he must. He
+looked at the disabled motor of the RED STREAK and viewed it with the
+interested and expert eye of a machinist, no matter if the owner of it
+was his enemy. Then suddenly a brilliant idea came into Tom's head.
+
+
+
+
+CHAPTER XVI
+
+STILL ON THE SEARCH
+
+
+"You seem to have lots of trouble with your boat, Andy," said Tom after
+a few moments of rather embarrassed silence.
+
+"I do," admitted the owner of the RED STREAK. "I've had bad luck ever
+since I got it, but usually I've been able to fix it by looking in the
+book. This time I can't find out what the trouble is, nor can any of
+the fellows. It stopped when we were out in the middle of the lake and
+we had to row. I'm sick of motor boating."
+
+"Suppose I fix it for you?" went on Tom.
+
+"If you do, I'll pay you well."
+
+"I wouldn't do it for pay--not the kind you mean," continued the young
+inventor.
+
+"What do you mean then?" and Andy's face, that had lighted up, became
+glum again.
+
+"Well, if I fix your boat for you, will you let me run it a little
+while?"
+
+"You mean show me how to run it?"
+
+"No, I mean take it myself. Look here, Andy, my boat's been stolen,
+and I thought you took it to get even with me. You say you didn't--"
+
+"And I didn't touch it," interposed the squint-eyed lad quickly.
+
+"All right, I believe you. But somebody stole it, and I think I know
+who."
+
+"Who?" asked Sam Snedecker.
+
+"Well, you wouldn't know if I told you, but I suspect some men with
+whom I had trouble before," and Tom referred to Happy Harry and his
+gang. "I think they have my boat on this lake, and I'd like to get
+another speedy craft to cruise about it and make a further search. How
+about it, Andy? If I fix your boat, will you let me take it to look
+for my boat?"
+
+"Sure thing!" agreed the bully quickly, and his voice for once was
+friendly toward Tom. "Fix the engine so it will run, and you can use
+the RED STREAK as long as you like."
+
+"Oh, I probably wouldn't want it very long. I could cover the lake in
+about three days, and I hope by that time I could locate the thieves.
+Is it a bargain?"
+
+"Sure," agreed Andy again, and Tom got into the motor-boat to look at
+the engine. He found that it would require some time to adjust it
+properly and that it would be necessary to take the motor apart.
+
+"I think I'd better tow you to my dock," the young inventor said to
+Andy. "I can use some tools from the shop then, and by to-night I'll
+have the RED STREAK in running order."
+
+The breeze was in the right quarter, fortunately, and with the
+motor-boat dragging behind, the ARROW's owner put the nose of the
+sailing craft toward his home dock.
+
+When Tom reached his house he found that Mrs. Baggert had received
+another telephone message from Mr. Swift, inquiring why his son had not
+returned to Sandport.
+
+"He says if you don't come back by to-morrow," repeated the
+housekeeper, "that he'll come home by train. He's getting anxious, I
+believe."
+
+"Shouldn't wonder," admitted Tom. "But I want him to stay there. The
+change will do him good. I'll soon have my boat back, now that I can
+go about the lake swiftly, and then I'll join him. I'll tell him to be
+patient."
+
+Tom talked with his father at some length, assuring him that everything
+was well at the Shopton house and promising to soon be with him. Then
+the young inventor began work on the motor of the RED STREAK. He found
+it quite a job and had to call on Mr. Jackson to help him, for one of
+the pistons had to be repaired and a number of adjustments made to the
+cylinders.
+
+But that night the motor was fully mended and placed back in the boat.
+It was in better shape than it had been since Andy had purchased the
+craft.
+
+"There," remarked Tom, "now I'm ready to hunt for those scoundrels.
+Will you leave your boat at my dock to-night, Andy?"
+
+"Yes, so you can start out early in the morning. I'm not going."
+
+"Why not?" demanded Tom quickly.
+
+"Well--er--you see I've had enough of motoring for a while," explained
+Andy. "Besides, I don't believe my mother would like me to go out on a
+chase after thieves. If we had to shoot I might hit one of them, and--"
+
+"Oh, I see," answered Tom. "But I don't like to take your boat alone.
+Besides, I don't fancy there will be much shooting. I know I'm not
+going to take a gun. In fact, the one Mr. Duncan gave me is in the
+boat. All I want is to get the ARROW back."
+
+"That's all right," went on Andy. "You take my boat and use it as long
+as you like. I'll rest up a few days. When you find your boat you can
+bring mine back."
+
+Tom understood. He was just as glad not to have Andy accompany him in
+the chase, as he and the red-haired lad had never been good friends and
+probably never would be. So it would cause some embarrassment to be
+together in a boat all day. Then again Tom knew he could manage the
+RED STREAK better alone, but, of course, he did not want to mention
+this when he asked for the loan of the craft. Andy's own suggestion,
+however, had solved the difficulty. Tom had an idea that Andy felt a
+little timid about going in pursuit of the thieves, but naturally it
+would not do to mention this, for the squint-eyed lad considered
+himself quite a fighter.
+
+Early the next morning, alone in the RED STREAK, Tom continued the
+search for his stolen boat. He started out from his home dock and
+mapped out a course that would take him well around the lake.
+
+"I s'pose I could take a run to Sandport now," mused the youth as he
+shot in and out of the little bays, keeping watch for the ARROW. "But
+if I do dad will have to be told all about it, and, he'll worry. Then,
+too, he might want to accompany me, and I think I can manage this
+better alone, for the RED STREAK will run faster with only one in. I
+ought to wind up this search in two days, if my boat is still on the
+lake. And if those scoundrels have sunk her I'll make them pay for it."
+
+On shot the speedy motor-boat, in and out along the winding shoreline,
+with the lad in the bow at the steering-wheel peering with eager eyes
+into every nook and corner where his craft might be hidden.
+
+
+
+
+CHAPTER XVII
+
+"THERE SHE IS!"
+
+
+Anticipating that he would be some time on his search, the young
+inventor had gone prepared for it. He had a supply of provisions and
+he had told Mrs. Baggert he might not be back that night. But he did
+not intend to sleep aboard the RED STREAK, which, being a racing boat,
+was not large enough to afford much room for passengers. Tom had
+planned, therefore, to put up at some hotel near the lake in case his
+hunt should last beyond one night.
+
+That it would do this was almost certain, for all that morning he
+searched unavailingly for the ARROW. A distant mill whistle sounding
+over Lake Carlopa told him it was noon.
+
+"Dinner time," he announced to himself. "Guess I'll run up along shore
+in the shade and eat."
+
+Selecting a place where the trees overhung the water, forming a quiet,
+cool nook, Tom sent the boat in there, and, tying it to a leaning tree,
+he began his simple meal. Various thoughts filled his mind, but chief
+among them was the desire to overtake the thieves who had his boat.
+That it was Happy Harry's gang he was positive.
+
+The lad nearly finished eating and was considering what direction he
+might best search in next when he heard, running along a road that
+bordered the lake, an automobile.
+
+"Wonder who that is?" mused Tom. "It won't do any harm to take a look,
+for it might be some of those thieves again. They probably still have
+their auto or Happy Harry couldn't have gotten from Sandport to Shopton
+so quickly."
+
+The young inventor slipped ashore from the motor-boat, taking care to
+make no noise. Stealing silently along toward the road, he peered
+through the underbrush for a sight of the machine, which seemed to be
+going slowly. But before the youth had a glimpse of it he was made
+aware who the occupant was by hearing someone exclaim:
+
+"Bless my shoe laces if this cantankerous contraption isn't going wrong
+again! I wonder if it's going to have a fit here in this lonely place.
+It acts just as if it was. Bless my very existence! Hold on now. Be
+nice! Be nice!"
+
+"Mr. Damon!" exclaimed Tom, and, without knowing it, he had spoken
+aloud.
+
+"Hold on there! Hold on! Who's calling me in this forsaken locality?
+Bless my shirt studs! But who is it?" and the eccentric man who had
+sold Tom the motor-cycle looked intently at the bushes.
+
+"Here I am, Mr. Damon," answered the lad, stepping out into the road.
+"I knew it was you as soon as I saw you."
+
+"Bless my liver, but that's very true! I suppose you heard my
+unfortunate automobile puffing along. I declare I don't know what ails
+it. I got it on the advice of my physician, who said I must get out in
+the air, but, bless my gears, it's the auto who needs a doctor more
+than I do! It's continually out of order. Something is going to
+happen right away. I can tell by the way it's behaving."
+
+Mr. Damon had thrown out the clutch, but the engine was still running,
+though in a jerky, uncertain fashion, which indicated to the trained
+ear of the young inventor that something was wrong.
+
+"Perhaps I can fix it for you as I did before," ventured Tom.
+
+"Bless my eyebrows! Perhaps you can," cried the eccentric man
+hopefully. "You always seem to turn up at the right moment. How do
+you manage it?"
+
+"I don't know. I remember the time you turned up just when I wanted
+you to help me capture Happy Harry and his gang, and now, by, a strange
+coincidence, I'm after them again."
+
+"You don't say so! My good gracious! Bless my hatband! But that's
+odd. There!" he ejaculated suddenly as the automobile engine stopped
+with a choking sigh, "I knew something was going to happen."
+
+"Let me take a look," proposed the lad, and he was soon busy peering
+into the interior of the machine. At first he could not find the
+trouble, but being a persistent youth, Tom went at it systematically
+and located it in two places. The clutch was not rightly adjusted and
+the carburetor float feed needed fixing. The young inventor was not
+long in making the slight repairs and then he assured Mr. Damon that
+his automobile would run properly.
+
+"Bless my very existence, but what a thing it is to have a head for
+mechanics!" exclaimed the odd man gratefully. "Now it would bother me
+to adjust a nutmeg grater if it got out of order, but I dare say you
+could fix it in no time."
+
+"Yes," answered Tom, "I could and so could you, for there's nothing
+about it to fix. But you can go ahead now if you wish."
+
+"Thank you. It just shows how ignorant I am of machinery. I presume
+something will go wrong in another mile or two. But may I ask what you
+are doing here? I presume you are in your motor-boat, sailing about
+for pleasure. And didn't I understand you to say you were after those
+chaps again? Bless my watch charm, but I was so interested in my
+machine that I didn't think to ask you."
+
+"Yes, I am after those thieves again."
+
+"In your motor-boat, I presume. Well, I hope you catch them. What
+have they stolen now?"
+
+"My motor-boat. That's why I'm after them, but I had to borrow a craft
+to chase them with."
+
+"Bless my soul! You don't tell me! How did it happen?"
+
+Thereupon the lad related as much of the story as was necessary to put
+Mr. Damon in possession of the facts and he ended up with:
+
+"I don't suppose you have seen anything of the men in my boat, have
+you?"
+
+Mr. Damon seemed strangely excited. He had entered his auto, but as
+the lad's story progressed the odd gentleman had descended. When Tom
+finished he exclaimed:
+
+"Don't say a word now--not a word. I want to think, and that is a
+process, which, for me, requires a little time. Don't speak a word
+now. Bless my left hand, but I think I can help you!"
+
+He frowned, stamped first one foot, then the other, looked up at the
+sky, as if seeking inspiration there, and then down at the ground, as
+if that would help him to think. Then he clapped his hands smartly
+together and cried out:
+
+"Bless my shoe buttons!"
+
+"Have you seen them?" asked Tom eagerly.
+
+"Was your boat one with a red arrow painted on the bow?" asked Mr.
+Damon in turn.
+
+"It was!" and the lad was now almost as excited as was his friend.
+
+"Then I've seen it and, what's more, this morning! Bless my spark
+plug, I've seen it!"
+
+"Tell me about it!" pleaded the young inventor, and Mr. Damon, calming
+himself after an effort, resumed:
+
+"I was out for an early spin in my auto," he said, "and was traveling
+along a road that bordered the lake, about fifteen miles above here. I
+heard a motor-boat puffing along near shore, and, looking through the
+trees, I saw one containing three men. It had a red arrow on the bow,
+and that's why I noticed it, because I recalled that your boat was
+named the DART."
+
+"ARROW," corrected Tom.
+
+"The ARROW. Oh, yes, I knew it was something like that. Well of
+course at the time I didn't think that it was your boat, but I
+associated it in my mind with yours. Do you catch my meaning?"
+
+Tom did and said so, wishing Mr. Damon would hurry and get to the
+point. But the eccentric character had to do things in his own way.
+
+"Exactly," he resumed. "Well, I didn't think that was your boat, but,
+at the same time, I watched the men out of curiosity, and I was struck
+with their behavior. They seemed to be quarreling, and, from what I
+could hear, two of them seemed to be remonstrating with the third one
+for having taken some sort of a piece of wood from the forward
+compartment. I believe that is the proper term."
+
+"Yes!" Tom almost shouted. "But where did they go? What became of
+them? What was the man doing to the forward compartment--where the
+gasoline tank is?"
+
+"Exactly. I was trying to think what was kept there. That's it, the
+gasoline tank. Well, the boat kept on up the lake, and I don't know
+what became of the men. But about that piece of wood. It seems that
+one of the men removed a block, from under the tank and the others
+objected. That's why they were quarreling."
+
+"That's very strange," exclaimed the lad. "There must be some mystery
+about my boat that I don't understand. But that will keep until I get
+the boat itself. Good-by, Mr. Damon. I must be off."
+
+"Where to?"
+
+"Up the lake after those thieves. I must lose no time," and Tom
+started to go back to where he had left the RED STREAK.
+
+"Hold on!" cried Mr. Damon. "I have something to propose, Tom. Two
+heads are better than one, even if one doesn't know how to adjust a
+nutmeg grate. Suppose I come along with you? I can point out the
+direction the men took, at any rate."
+
+"I'll be very glad to have you," answered the lad, who felt that he
+might need help if there were three of the thieves in his craft. "But
+what will you do with your automobile?"
+
+"I'll just run it down the road a way to where a friend of mine has a
+stable. I'll leave it in there and join you. Will you let me come?
+Bless my eye glasses, but I'd like to help catch those scoundrels!"
+
+"I'll be very glad to have you. Go ahead, put the auto in the barn and
+I'll wait for you."
+
+"I have a better plan than that," replied Mr. Damon. "Run your boat
+down to that point," and he indicated one about a mile up the lake.
+"I'll be there waiting for you, and we'll lose no time. I can cover
+the ground faster in my auto than you can in your boat."
+
+Tom saw the advantage of this and was soon under way, while he heard on
+shore the puffing of his friend's car. On the trip to the point Tom
+puzzled over the strange actions of the man in taking one of the braces
+from under the gasoline tank.
+
+"I'll wager he did it before," thought the lad. "It must be the same
+person who was tampering with the lock of the forward compartment the
+day I bought the boat. But why--that's the question--why?"
+
+He could find no answer to this, puzzle over it as he did, and he gave
+it up. His whole desire now was to get on the trail of the thieves,
+and he had strong hopes, after the clew Mr. Damon had given him. The
+latter was waiting for him on the point, and so nimble was the owner of
+the auto, in spite of his size, that Tom was not delayed more than the
+fraction of a minute ere he was under way again, speeding up the lake.
+
+"Now keep well in toward shore," advised Mr. Damon. "Those fellows
+don't want to be observed any more than they can help, and they'll
+sneak along the bank, They were headed in that direction," and he
+pointed it out. "Now I hope you won't think I'm in the way. Besides,
+you know, if you get your boat back, you'll want some one to help steer
+it, while you run this one. I can do that, at all events, bless my
+very existence!"
+
+"I am very glad of your help," replied the lad, but he did not take his
+eyes from the water before him, and he was looking for a sight of his
+boat with the men in it.
+
+For three hours or more Tom and Mr. Damon cruised in and out along the
+shore of the lake, going farther and farther up the body of water. Tom
+was beginning to think that he would reach Sandport without catching
+sight of the thieves, and he was wondering if, after all, he might not
+better stop off and see his father when, above the puffing of the motor
+in the RED STREAK, he heard the put-put of another boat.
+
+"Listen!" cried Mr. Damon, who had heard it at the same time.
+
+Tom nodded.
+
+"They're just ahead of us," whispered his companion.
+
+"If it's them," was the lad's reply.
+
+"Speed up and we'll soon see," suggested Mr. Damon, and Tom shoved the
+timer over. The RED STREAK forged ahead. The sound of the other boat
+came more plainly now. It was beyond a little point of land. The
+young inventor steered out to get around it and leaned eagerly forward
+to catch the first glimpse of the unseen craft. Would it prove to be
+the ARROW?
+
+The put-put became louder now. Mr. Damon was standing up, as if that
+would, in some mysterious way, help. Then suddenly the other boat came
+into view. Tom saw it in an instant and knew it for the ARROW.
+
+"There she is!" he cried.
+
+
+
+
+CHAPTER XVIII
+
+THE PURSUIT
+
+
+For an instant after Tom's exultant cry the men in the boat ahead were
+not aware that they were being pursued. Then, as the explosions from
+the motor of the RED STREAK sounded over the water, they turned to see
+who was coming up behind them. There was no mistaking the attitude of
+the young inventor and his companion. They were leaning eagerly
+forward, as if they could reach out and grasp the criminals who were
+fleeing before them.
+
+"Put on all the speed you can, Tom!" begged Mr. Damon. "We'll catch
+the scoundrels now. Speed up the motor! Oh, if I only had my
+automobile now. Bless my crank shaft, but one can go so much faster on
+land than on water."
+
+The lad did not reply, but thought, with grim humor, that running an
+automobile over Lake Carlopa would be no small feat. Mr. Damon,
+however, knew what he was saying.
+
+"We'll catch them! We'll nab 'em!" he cried. "Speed her up, Tom."
+
+The youth was doing his best with the motor of the RED STREAK. He was
+not as well acquainted with it as he was with the one in his boat, but
+he knew, even better than Andy Foger, how to make it do efficient work.
+It was a foregone conclusion that the RED STREAK, if rightly handled,
+could beat the ARROW, but there were several points in favor of the
+thieves. The motor of Tom's boat was in perfect order, and even an
+amateur, with some knowledge of a boat, could make it do nearly its
+best. On the other hand, the RED STREAK's machinery needed "nursing."
+Again, the thieves had a good start, and that counted for much. But
+Tom counted on two other points. One was that Happy Harry and his gang
+would probably know little about the fine points of a motor. They had
+shown this in letting the motor of the boat they had first stolen get
+out of order, and Tom knew the ins and outs of a gasoline engine to
+perfection. So the chase was not so hopeless as it seemed.
+
+"Do you think you can catch them?" asked Mr. Damon anxiously.
+
+"I'm going to make a big try," answered his companion.
+
+"They're heading out into the middle of the lake!" cried the eccentric
+man.
+
+"If they do, I can cut them off!" murmured Tom as he put the wheel over.
+
+But whoever was steering the ARROW knew better than to send it on a
+course that would enable the pursuing boat to cut across and shorten
+the distance to it. After sending the stolen craft far enough out from
+shore to clear points of land that jutted out into the lake, the
+leading boat was sent straight ahead.
+
+"A stern chase and a long chase!" murmured Mr. Damon. "Bless my
+rudder, but those fellows are not going to give up easily."
+
+"I guess not," murmured Tom. "Will you steer for a while, Mr. Damon?"
+
+"Of course I will. If I could get out and pull the boat after me, to
+make it go faster, I would. But as I always lose my breath when I run,
+perhaps it's just as well that I stay in here." Tom thought so too,
+but his attention was soon given to the engine. He adjusted the timer
+to get if possible a little more speed out of the boat he had borrowed
+from Andy, and he paid particular attention to the oiling system.
+
+"We're going a bit faster!" called Mr. Damon' encouragingly, "or else
+they're slacking up."
+
+Tom peered ahead to see if this was so. It was hard to judge whether
+he was overhauling the ARROW, as it was a stern chase, and that is
+always difficult to judge. But a glimpse along shore showed him that
+they were slipping through the water at a faster speed.
+
+"They're up to something!" suddenly exclaimed Mr. Damon a moment later.
+"I believe they're going to fire on us, Tom. They are pointing
+something this way."
+
+The lad stood up and gazed earnestly at his boat, which seemed to be
+slipping away from him so fast. One of the occupants was in the stern,
+aiming some glittering object at those in the RED STREAK. For a moment
+Tom thought it might be a gun. Then, as the man turned, he saw what it
+was.
+
+"A pair of marine glasses," cried the lad. "They're trying to make out
+who we are."
+
+"I guess they know well enough," rejoined Mr. Damon. "Can't you go any
+faster, Tom?"
+
+"I'm afraid not. But we'll land them, sooner or later. They can't go
+very far in this direction without running ashore and we'll have them.
+They're cutting across the lake now."
+
+"They may escape us if it gets dark. Probably that's what they're
+working for. They want to keep ahead of us until nightfall."
+
+The young inventor thought of this too, but there was little he could
+do. The motor was running at top speed. It could be made to go
+faster, Tom knew, with another ignition system, but that was out of the
+question now.
+
+The man with the glasses had resumed his seat, and the efforts of the
+trio seemed concentrated on the motor of the ARROW. They, too, wished
+to go faster. But they had not skill enough to accomplish it, and in
+about ten minutes, when Tom took another long and careful look to
+ascertain if possible whether or not he was overhauling the thieves, he
+was delighted to see that the distance between the boats had lessened.
+
+"We're catching them! We're creeping up on them!" cried Mr. Damon.
+"Keep it up, Tom." There was nothing to do, however, save wait. The
+boat ahead had shifted her course somewhat and was now turning in
+toward the shore, for the lake was narrow at this point, and abandoning
+their evident intention of keeping straight up the lake, the thieves
+seemed now bent on something else.
+
+"I believe they're going to run ashore and get out!" cried Mr. Damon.
+
+"If they do, it's just what I want," declared the lad. "I don't care
+for the men. I want my boat back!"
+
+The occupants of the ARROW were looking to the rear again, and
+one--Happy Harry, Tom thought--shook his fist.
+
+"Ah, wait until I get hold of you!" cried Mr. Damon, following his
+example. "I'll make you wish you'd behaved yourselves, you scoundrels!
+Bless my overcoat! Catch them if you can, Tom."
+
+There was now no doubt of the intention of the fleeing ones. The shore
+was looming up ahead and straight for it was headed the ARROW. Tom
+sent Andy's boat in the same direction. He was rapidly overhauling the
+escaping ones now, for they had slowed down the motor. Three minutes
+later the foremost boat grated on the beach of the lake. The men
+leaped out, one of them pausing an instant in the bow.
+
+"Here, don't you damage my boat!" cried Tom involuntarily, for the man
+seemed to be hammering something.
+
+The fellow leaped over the side, holding something in his hand.
+
+"There they go! Catch them!" yelled Mr. Damon.
+
+"Let them go!" answered the lad as the men ran toward the wood. "I
+want my boat. I'm afraid they've damaged her. One of them tore
+something from the bow."
+
+At the same instant the two companions of the fellow who had paused in
+the forward part of the ARROW saw that he had something in his hand.
+With yells of rage they dashed at him, but he, shaking his fist at
+them, plunged into the bushes and could be heard breaking his way
+through, while his companions were in pursuit.
+
+"They've quarreled among themselves," commented Mr. Damon as high and
+angry voices could be heard from the woods. "There's some mystery
+here, Tom."
+
+"I don't doubt it, but my first concern is for my boat. I want to see
+if they have damaged her."
+
+Tom had run so closely in shore with the RED STREAK that he had to
+reverse to avoid damaging the craft against the bank. In a mass of
+foam he stopped her in time, and then springing ashore, he hurried to
+his motor-boat.
+
+
+
+
+CHAPTER XIX
+
+A QUIET CRUISE
+
+
+"Have they done any damage?" asked Mr. Damon as he stood in the bow of
+the RED STREAK.
+
+Tom did not answer for a moment. His trained eye was looking over the
+engine.
+
+"They yanked out the high tension wire instead of stopping the motor
+with the switch," he answered at length, and then, when he had taken a
+look into the compartment where the gasoline tank was, he added: "And
+they've ripped out two more of the braces I put in. Why in the world
+they did that I can't imagine."
+
+"That's evidently what one man had that the others wanted," was Mr.
+Damon's opinion.
+
+"Probably," agreed Tom. "But what could he or they want with wooden
+braces?"
+
+That was a puzzler for Mr. Damon, but he answered:
+
+"Perhaps they wanted to damage your boat and those two men were mad
+because the other got ahead of them."
+
+"Taking out the braces wouldn't do much damage. I can easily put
+others in. All it would do would be to cause the tank to sag down and
+maybe cause a leak in the pipe. But that would be a queer thing to do.
+No, I think there's some mystery that I haven't gotten to the bottom of
+yet. But I'm going to."
+
+"Good!" exclaimed Mr. Damon. "I'll help you. But can you run your
+boat back home?"
+
+"Not without fixing it a bit. I must brace up that tank and put in a
+new high-tension wire from the spark coil. I can do it here, but I'd
+rather take it to the shop. Besides, with two boats to run back, for I
+must return Andy's to him, I don't see how I can do it very well unless
+you operate one, Mr. Damon."
+
+"Excuse me, but I can't do it. Bless my slippers, but I would be sure
+to run on a rock! The best plan will be for you to tow your boat and
+I'll ride in it and steer. I can do that much, anyhow. You can ride
+in the RED STREAK."
+
+Tom agreed that this would be a good plan. So, after temporarily
+bracing up the tank in the ARROW, it was shoved out into the lake and
+attached to Andy's craft.
+
+"But aren't you going to make a search for those men?" asked Mr. Damon
+when Tom was ready to start back.
+
+"No, I think it would be useless. They are well away by this time, and
+I don't fancy chasing them through the woods, especially as night is
+coming on. Besides, I won't leave these boats."
+
+"No doubt you are right, but I would like to see them punished, and I
+am curious enough to wish to know what object that scoundrel could have
+in ripping out the blocks that served as a brace for the tank."
+
+"I feel the same way myself," commented the lad, "especially since this
+is the second time that's happened. But we'll have to wait, I guess."
+
+A little later the start back was made, Mr. Damon steering the ARROW
+skillfully enough so that it did not drag on the leading boat, in which
+Tom rode. His course took him not far from the lake sanitarium, where
+Mr. Duncan, the hunter, had been brought, and desiring to know how the
+wounded man was getting on, the youth proposed that they make a halt,
+explaining to Mr. Damon his reason.
+
+"Yes, and while you're about it you'd better telephone your father that
+you will join him to-morrow," suggested the other. "I know what it is
+to fret and worry. You can fix your boat up in time to go to Sandport
+to-morrow, can't you?"
+
+"Yes, I'm glad you reminded me of it. I'll telephone from the
+sanitarium, if they'll let me."
+
+Mr. Duncan was not at the institution, Tom was told, his injury having
+healed sufficiently to allow of his being removed to his home. The
+youth readily secured permission to use the telephone, and was soon in
+communication with Mr. Swift. While not telling him all the
+occurrences that had delayed him, Tom gave his father and Ned Newton
+enough information to explain his absence. Then the trip to Shopton
+was resumed in the two boats.
+
+"What are you going to do about your automobile?" asked Tom as they
+neared the point where the machine had been left.
+
+"Never mind about that," replied Mr. Damon. "It will do it good to
+have a night's vacation. I will go on to your house with you, and
+perhaps I can get a train back to my friend's home, so that I can claim
+my car."
+
+"Won't you stay all night with me?" invited the young inventor. "I'd
+be glad to have you."
+
+Mr. Damon agreed, and, Tom putting more speed on the RED STREAK, was
+soon opposite his own dock. The ARROW was run in the boathouse and the
+owner hastily told Mrs. Baggert and the engineer what had occurred.
+Then he took Andy's boat to Mr. Foger's dock and warmly thanked the
+red-haired lad for the use of his craft.
+
+"Did you find your boat?" asked Andy eagerly. "How did the RED STREAK
+run?"
+
+"I got my boat and yours runs fine," explained Tom.
+
+"Good! I'll race you again some day," declared Andy.
+
+Mr. Damon enjoyed his visit at our hero's house, for Mrs. Baggert
+cooked one of her best suppers for him. Tom and the engineer spent the
+evening repairing the motor-boat, Mr. Damon looking on and exclaiming
+"Bless my shoe leather" or some other part of his dress or anatomy at
+every stage of the work. The engineer wanted to know all about the men
+and their doings, but he could supply no reason for their queer actions
+regarding the braces under the gasoline tank.
+
+In the morning Tom once more prepared for an early start for Sandport,
+and Mr. Damon, reconsidering his plans, rode as far with him as the
+place where the automobile had been left. There he took leave of the
+young inventor, promising to call on Mr. Swift in the near future.
+
+"I hope you arrive at the hotel where your father is without any more
+accidents," remarked the automobilist. "Bless my very existence, but
+you seem to have the most remarkable series of adventures I ever heard
+of!"
+
+"They are rather odd," admitted Tom. "I don't know that I particularly
+care for them, either. But, now that I have my boat back, I guess
+everything will be all right."
+
+But Tom could not look ahead. He was destined to have still more
+exciting times, as presently will be related.
+
+Without further incident he arrived at the Lakeview Hotel in Sandport
+that evening and found his father and Ned very glad to see him. Of
+course he had to explain everything then, and, with his son safely in
+his sight, Mr. Swift was not so nervous over the recital as he would
+have been had Tom not been present.
+
+"Now for some nice, quiet trips," remarked the lad when he had finished
+his account. "I feel as if I had cheated you out of part of your
+vacation, Ned, staying away as long as I did."
+
+"Well, of course we missed you," answered his chum. "But your father
+and I had a good time."
+
+"Yes, and I invented a new attachment for a kitchen boiler," added Mr.
+Swift. "I had a chance for it when I passed through the hotel kitchen
+one day, for I wanted to see what kind of a range they used."
+
+"I guess there's no stopping you from inventing," replied his son with
+a laugh and a hopeless shake of the head. "But don't let it happen
+again when you go away to rest."
+
+"Oh, I only just thought of it," said Mr. Swift. "I haven't worked the
+details out yet."
+
+Then he wanted to know about everything at home and he seemed
+particularly anxious lest the Happy Harry gang do some damage.
+
+"I don't believe they will," Tom assured him. "Garret and Mrs. Baggert
+will be on guard."
+
+The next few days were pleasant ones for Tom, his father and Ned
+Newton. They cruised about the lake, went fishing and camped in the
+woods. Even Mr. Swift spent one night in the tent and said he liked it
+very much. For a week the three led an ideal existence, going about as
+they pleased, Ned taking a number of photographs with his new camera.
+The ARROW proved herself a fine boat, and Tom and Ned, when Mr. Swift
+did not accompany them, explored the seldom visited parts of Lake
+Carlopa.
+
+The three had been out one day and were discussing the necessity of
+returning home soon when Ned spoke.
+
+"I shall hate to give up this life and go to slaving in the bank
+again," he complained. "I wish I was an inventor."
+
+"Oh, we inventors don't have such an easy time," said Mr. Swift. "You
+never know when trouble is coming," and he little imagined how near the
+truth he was.
+
+A little later they were at the hotel dock. When Tom had tied up his
+boat the three walked up the path to the broad veranda that faced the
+lake. A boy in uniform met them.
+
+"Some one has just called you on the telephone, Mr. Swift," he reported.
+
+"Some one wants me? Who is it?"
+
+"I think he said his name is Jackson, sir, Garret Jackson, and he says
+the message is very important."
+
+"Tom, something has happened at home!" exclaimed the inventor as he
+hurried up the steps. "I'm afraid there's bad news."
+
+Unable to still the fear in his heart, Tom followed his father.
+
+
+
+
+CHAPTER XX
+
+NEWS OF A ROBBERY
+
+
+With a hand that trembled so he could scarcely hold the receiver of the
+telephone, Mr. Swift placed it to his ear.
+
+"Hello! Hello!" he cried into the transmitter. "Yes, this is Mr.
+Swift--yes, Garret. What is it?"
+
+Then came a series of clicks, which Tom and Ned listened to. The
+inventor spoke again.
+
+"What's that? The same men? Broke in early this evening? Oh, that's
+too bad! Of course, I'll come at once."
+
+There followed more meaningless clicks, which Tom wished he could
+translate. His father hung up the receiver, turned to him and
+exclaimed:
+
+"I've been robbed again!"
+
+"Robbed again! How, dad?"
+
+"By that same rascally gang, Garret thinks. This evening, when he and
+Mrs. Baggert were in the house the burglar alarm went off. The
+indicator showed that the electrical shop had been entered, and the
+engineer hurried there. He saw a light inside and the shadows of
+persons on the windows. Before he could reach the shop, however, the
+thieves heard him coming and escaped. Oh, Tom, I should never have
+come away!"
+
+"But did they take anything, dad? Perhaps Garret frightened them away
+before they had a chance to steal any of your things. Did you ask him
+that?"
+
+"I didn't need to. He said he made a hasty exanimation before he
+called me up, and he is sure a number of my electrical inventions are
+missing. Some of them are devices I never have had patented, and if I
+lose them I will have no recovery."
+
+"But just what ones are they? Perhaps we can send out a police alarm
+to-night."
+
+"Garret couldn't tell that," answered Mr. Swift as he paced to and fro
+in the hotel office. "He doesn't know all the tools and machinery I
+had in there. But it is certain that some of my most valuable things
+have been taken."
+
+"Never mind. Don't worry, dad," and Tom tried to speak soothingly, for
+he saw that his father was much excited. "We may be able to get them
+back. How does Garret know the same men who stole the turbine model
+broke in the shop this evening?"
+
+"He saw them. One was Happy Harry, he is positive. The others he did
+not know, but he recognized the tramp from our description of him."
+
+"Then we must tell the police at once."
+
+"Yes, Tom, I wish you would telephone. I'll give you a description of
+the things. No, I can't do that either, for I don't know what was
+stolen. I must go home at once to find out. It's a good thing the
+motor-boat is here. Come, let's start at once. What is my bill here?"
+and the inventor turned to the hotel proprietor, who had come into the
+office. "I have suffered a severe loss and must leave at once."
+
+"I am very sorry, sir. I'll have it ready for you in a few minutes."
+
+"All right. Tom, is your boat ready for a quick trip?"
+
+"Yes, dad, but I don't like to make it at night with three in. Of
+course it might be perfectly safe, but there's a risk, and I don't like
+to take it."
+
+"Don't worry about the risk on my account, Tom. I'm not afraid. I
+must get home and see of what I have been robbed."
+
+The young inventor was in a quandary. He wanted to do as his father
+requested and to aid him all he could, yet he knew that an all-night
+trip in the boat down the lake would be dangerous, not only from the
+chance of running on an unknown shore or into a hidden rock, but
+because Mr. Swift was not physically fitted to stand the journey.
+
+"Come, Tom," exclaimed the aged inventor impatiently, "we must start at
+once!"
+
+"Won't morning do as well, dad?"
+
+"No, I must start now. I could not sleep worrying over what has
+happened. We will start--"
+
+At that instant there came a low, rumbling peal of thunder. Mr. Swift
+started and peered from a window. There came a flash of lightning and
+another vibrant report from the storm-charged clouds.
+
+"There is your bill, Mr. Swift," remarked the proprietor, coming up,
+"but I would not advise you to start to-night. There is a bad storm in
+the west, and it will reach here in a few minutes. Storms on Lake
+Carlopa, especially at this open and exposed end, are not to be
+despised, I assure you."
+
+"But I must get home!" insisted Tom's father.
+
+The lace curtain over the window blew almost straight out with a sudden
+breeze, and a flash of lightning so bright that it reflected even in
+the room where the incandescent electrics were glowing made several
+others jump. Then came a mighty crash, and with that the flood-gates
+of the storm were opened, and the rain came down in torrents. Tom
+actually breathed a sigh of relief. The problem was solved for him.
+It would be impossible to start to-night, and he was glad of it, much
+as he wanted to get on the trail of the thieves.
+
+There was a scurrying on the part of the hotel attendants to close the
+windows, and the guests who had been enjoying the air out on the
+porches came running in. With a rush, a roar and a muttering, as peal
+after peal of thunder sounded, the deluge continued.
+
+"It's a good thing we didn't start," observed Ned.
+
+"I should say so," agreed Tom. "But we'll get off the first thing in
+the morning, dad."
+
+Mr. Swift did not reply, but his nervous pacing to and fro in the hotel
+office showed how anxious he was to be at home again. There was no
+help for it, however, and, after a time, finding that to think of
+reaching his house that night was out of the question, the inventor
+calmed down somewhat.
+
+The storm continued nearly all night, as Tom could bear witness, for he
+did not sleep well, nor did his father. And when he came down to
+breakfast in the morning Mr. Swift plainly showed the effects of the
+bad news. His face was haggard and drawn and his eyes smarted and
+burned from lack of sleep.
+
+"Well, Tom, we must start early," he said nervously. "I am glad it has
+cleared off. Is the boat all ready?"
+
+"Yes, and it's a good thing it was under shelter last night or we'd
+have to bail it out now, and that would delay us."
+
+An hour later they were under way, having telephoned to the engineer at
+the Swift home that they were coming. Garret Jackson reported over the
+wire that he had notified the Shopton police of the robbery, but that
+little could be done until the inventor arrived to give a description
+of the stolen articles.
+
+"And that will do little good, I fear," remarked Tom. "Those fellows
+have evidently been planning this for some time and will cover their
+tracks well. I'd like to catch them, not only to recover your things,
+dad, but to find out the mystery of my boat and why the man took the
+tank braces."
+
+
+
+
+CHAPTER XXI
+
+THE BALLOON ON FIRE
+
+
+Down Lake Carlopa speeded the ARROW, those on board watching the banks
+slip past as the motor-boat rapidly cut through the water.
+
+"What time do you think we ought to reach home, Tom?" asked Mr. Swift.
+
+"Oh, about four o'clock, if we don't stop for lunch."
+
+"Then we'll not stop," decided the inventor. "We'll eat what we have
+on board. I suppose you have some rations?" and he smiled, the first
+time since hearing the bad news.
+
+"Oh, yes, Ned and I didn't eat everything on our camping trips," and
+Tom was glad to note that the fine weather which followed the storm was
+having a good effect on his father.
+
+"We certainly had a good time," remarked Ned. "I don't know when I've
+enjoyed a vacation so."
+
+"It's too bad it had to be cut short by this robbery," commented Mr.
+Swift.
+
+"Oh, well, my time would be up in a few days more," went on the young
+bank employee. "It's just as well to start back now."
+
+Tom took the shortest route he knew, keeping in as close to shore as he
+dared, for now he was as anxious to get home as was his father. On and
+on speeded the ARROW, yet fast as it was, it seemed slow to Mr. Swift,
+who, like all nervous persons, always wanted to go wherever he desired
+to go instantly.
+
+Tom headed his boat around a little point of land, and was urging the
+engine to the top notch of speed, for now he was on a clear course,
+with no danger from shoals or hidden rocks, when he saw, darting out
+from shore, a tiny craft which somehow seemed familiar to him. He
+recognized a peculiar put-putter of the motor.
+
+"That's the DOT," he remarked in a low voice to Ned, "Miss Nestor's
+cousin's boat."
+
+"Is she in it now?" asked Ned.
+
+"Yes," answered Tom quickly.
+
+"You've got good eyesight," remarked Ned dryly, "to tell a girl at that
+distance. It looks to me like a boy."
+
+"No, it's Mary--I mean Miss Nestor," the youth quickly corrected
+himself, and a close observer would have noticed that he blushed a bit
+under his coat of tan.
+
+Ned laughed, Tom blushed still more, and Mr. Swift, who was in a stern
+seat, glanced up quickly.
+
+"It looks as if that boat wanted to hail us," the inventor remarked.
+
+Tom was thinking the same thing, for, though he had changed his course
+slightly since sighting the DOT, the little craft was put over so as to
+meet him. Wondering what Miss Nestor could want, but being only too
+willing to have a chat with her, the young inventor shifted his helm.
+In a short time the two craft were within hailing distance.
+
+"How do you do?" called Miss Nestor, as she slowed down her motor.
+"Don't you think I'm improving, Mr. Swift?"
+
+"What's that? I--er--I beg your pardon, but I didn't catch that,"
+exclaimed the aged inventor quickly, coming out of a sort of day-dream.
+"I beg your pardon." He thought she had addressed him.
+
+Miss Nestor blushed and looked questioningly at Tom.
+
+"My father," he explained as he introduced his parent. Ned needed
+none, having met Miss Nestor before. "Indeed you have improved very
+much," went on our hero. "You seem able to manage the boat all alone."
+
+"Yes, I'm doing pretty well. Dick lets me take the DOT whenever I want
+to, and I thought I'd come out for a little trial run this morning.
+I'm getting ready for the races. I suppose you are going to enter
+them?" and she steered her boat alongside Tom's, who throttled down his
+powerful motor so as not to pass his friend.
+
+"Races? I hadn't heard of them," he replied.
+
+"Oh, indeed there are to be fine ones under the auspices of the Lanton
+Motor Club. Mr. Hastings, of whom you bought that boat, is going to
+enter his new CARLOPA, and Dick has entered the DOT, in the baby class
+of course. But I'm going to run it, and that's why I'm practicing."
+
+"I hope you win," remarked Tom. "I hadn't heard of the races, but I
+think I'll enter. I'm glad you told me. Do you want to race now?" and
+he laughed as he looked into the brown eyes of Mary Nestor.
+
+"No, indeed, unless you give me a start of several miles."
+
+They kept together for some little time longer, and then, as Tom knew
+his father would be restless at the slow speed, he told Miss Nestor the
+need of haste, and, advancing his timer, he soon left the DOT behind.
+The girl called a laughing good-by and urged him not to forget the
+races, which were to take place in about two weeks.
+
+"I suppose Andy Foger will enter his boat," commented Ned.
+
+"Naturally," agreed Tom. "It's a racer, and he'll probably think it
+can beat anything on the lake. But if he doesn't manage his motor
+differently, it won't."
+
+The distance from Sandport to Shopton had been more than half covered
+at noon, when the travelers ate a lunch in the boat. Mr. Swift was
+looking anxiously ahead to catch the first glimpse of his dock and Tom
+was adjusting the machinery as finely as he dared to get out of it the
+maximum speed.
+
+Ned Newton, who happened to be gazing aloft, wondering at the perfect
+beauty of the blue sky after the storm, uttered a sudden exclamation.
+Then he arose and pointed at some object in the air.
+
+"Look!" he cried, "A balloon! It must have gone up from some fair."
+
+Tom and his father looked upward. High in the air, almost over their
+heads, was an immense balloon. It was of the hot-air variety, such as
+performers use in which to make ascensions from fair grounds and
+circuses, and below it dangled a trapeze, upon which could be observed
+a man, only he looked more like a doll than a human being.
+
+"I shouldn't like to be as high as that," remarked Ned.
+
+"I would," answered Tom as he slowed down the engine the better to
+watch the balloon. "I'd like to go up in an airship, and I intend to
+some day."
+
+"I believe he's going to jump!" suddenly exclaimed Ned after a few
+minutes. "He's going to do something, anyhow."
+
+"Probably come down in a parachute," said Tom. "They generally do
+that."
+
+"No! No!" cried Ned. "He isn't going to jump. Something has
+happened! The balloon is on fire! He'll be burned to death!"
+
+Horror stricken, they all gazed aloft. From the mouth of the balloon
+there shot a tongue of fire, and it was followed by a cloud of black
+smoke. The big bag was getting smaller and seemed to be descending,
+while the man on the trapeze was hanging downward by his hands to get
+as far as possible away from the terrible heat.
+
+
+
+
+CHAPTER XXII
+
+THE RESCUE
+
+
+"Jump! Jump!" cried Mr. Swift, leaping to his feet and motioning to
+the man on the trapeze of the balloon. But it is doubtful whether or
+not the performer heard him. Certainly he could not see the frantic
+motions of the inventor. "Why doesn't he jump?" Mr. Swift went on
+piteously to the two lads. "He'll surely be burned to death if he
+hangs on there!"
+
+"It's too far to leap!" exclaimed Tom. "He's a good way up in the air,
+though it looks like only a short distance. He would be killed if he
+dropped now."
+
+"He ought to have a parachute," added Ned. "Most of those men do when
+they go up in a balloon. Why doesn't he come down in that? I wonder
+how the balloon took fire?"
+
+"Maybe he hasn't a parachute," suggested Tom, while he slowed down the
+motor-boat still more so as to remain very nearly under the blazing
+balloon.
+
+"Yes, he has!" cried Ned. "See, it's hanging to one side of the big
+bag. He ought to cut loose. He could save himself then. Why doesn't
+he?"
+
+The balloon was slowly twisting about, gradually settling to the
+surface of the lake, but all the while the flames were becoming fiercer
+and the black clouds of smoke increased in size.
+
+"There, see the parachute!" went on Ned.
+
+The twisting of the bag had brought into view the parachute or big,
+umbrella-shaped bag, which would have enabled the man to safely drop to
+the surface of the lake. Without it he would have hit the water with
+such force that he would have been killed as surely as if he had struck
+the solid earth. But the boys and Mr. Swift also saw something else,
+and this was that the balloon was on fire on the same side where the
+parachute was suspended.
+
+"Look! Look!" shouted Tom, bringing his boat to a stop. "That's why he
+can't jump! He can't reach the parachute!"
+
+By this time the balloon had settled so low that the actions of the man
+could be plainly seen. That he was in great agony of fear, as well as
+in great pain from the terrific heat over his head was evident. He
+shifted about on the trapeze bar, now hanging by one hand, so as to
+bring his body a little farther below the blazing end of the bag, then,
+when one arm tired, he would hang by the other. If the balloon would
+only come down more quickly it would get to within such a short
+distance of the water that the man could safely make the drop. But the
+immense canvas bag was settling so slowly, for it was still very
+buoyant, that considerable time must elapse before it would be near
+enough to the water to make it safe for the unfortunate man to let go
+the trapeze.
+
+"Oh, if we could only do something!" cried Tom. "We have to remain
+here helpless and watch him burn to death. It's awful!"
+
+The three in the boat continued to gaze upward. They could see the man
+making frantic efforts to reach his parachute from time to time. Once,
+as a little current of air blew the flames and smoke to one side, he
+thought he had a chance. Up on the trapeze bar he pulled himself and
+then edged along it in an endeavor to grasp the ring of the parachute.
+Once he almost had hold of that and also the cord, which ran to a knife
+blade. This cord, being pulled, would sever the rope that bound it to
+the balloon, and he would be comparatively safe, so he might drop to
+the lake. But, just as he was about to grasp the ring and cord the
+smoke came swirling down on him and the hungry flames seemed to put out
+their fiery tongues to devour him. He had to slide back and once more
+hung by his hands.
+
+"I thought he was saved then," whispered Tom, and even the whisper
+sounded loud in the silence.
+
+Several men came running along the shore of the lake now. They saw the
+occupants in the ARROW and cried out:
+
+"Why don't you save him? Go to his rescue!"
+
+"What can we do?" asked Ned quietly of his two friends, but he did not
+trouble to answer the men on shore, who probably did not know what they
+were saying.
+
+The motor-boat had drifted from a spot under the unfortunate
+balloonist, and at a word from his father the young inventor started
+the engine and steered the craft back directly under the blazing bag
+again.
+
+"If he does drop, perhaps we may be able to pick him up," said Mr.
+Swift. "I wish we could save him!"
+
+A cry from Ned startled Tom and his father, and their eyes, that had
+momentarily been directed away from the burning bag high in the air,
+were again turned toward it.
+
+"The balloon is falling apart!" exclaimed Ned. "It's all up with him
+now!"
+
+Indeed it did seem so, for pieces of the burning canvas, blazing and
+smoking, were falling in a shower from the part of the bag already
+consumed, and the fiery particles were fairly raining down on the man.
+But he still had his wits about him, though his perilous position was
+enough to make any one lose his mind, and he swung from side to side on
+the bar, shifting skillfully with his hands and dodging the larger
+particles of blazing canvas. When some small sparks fell on his
+clothing he beat them out with one hand, while with the other he clung
+to the trapeze.
+
+There was scarcely any wind or the man's plight might have been more
+bearable, for the current of air would have carried the smoke and fire
+to one side. As it was, most of the smoke and flames went straight up,
+save now and then, when a draught created by the heat would swirl the
+black clouds down on the performer, hiding him from sight for a second
+or two. A breeze would have carried the sparks away instead of letting
+them fall on him.
+
+Nearer and nearer to the surface of the lake sank the balloon. By this
+time the crowd on the bank had increased and there were excited
+opinions as to what was best to do. But the trouble was that little
+could be done. If the man could hold out until he got near enough to
+the water to let go he might yet be saved, but this would not be for
+some time at the present rate the balloon was falling. The performer
+realized this, and, as the fire was getting hotter, he made another
+desperate attempt to reach the parachute. It was unavailing and he had
+to drop back, hanging below the slender bar.
+
+Suddenly there came a puff of wind, fanning the faces of those in the
+motor-boat, and they looked intently to observe if there was any
+current as high as was the balloonist. They saw the big bag sway to
+one side and the flames broke out more fiercely as they caught the
+draught. The balloon moved slowly down the lake.
+
+"Keep after it, Tom!" urged his father. "We may be able to save him!"
+
+The lad increased the speed of his engine and Ned, who was at the
+wheel, gave it a little twist. Then, with a suddenness that was
+startling, the blazing canvas airship began to settle swiftly toward
+the water. It had lost much of its buoyancy.
+
+"Now he can jump! He's near enough to the water now!" cried Tom.
+
+But a new danger arose. True, the balloon was rapidly approaching the
+surface of the lake and in a few seconds more would be within such a
+short distance that a leap would not be fatal. But the burning bag was
+coming straight down and scarcely would the man be in the water ere the
+fiery canvas mass would be on top of him.
+
+In such an event he would either be burned to death or so held down
+that drowning must quickly follow.
+
+"If there was only wind enough to carry the balloon beyond him after he
+jumped he could do it safely!" cried Ned.
+
+Tom said nothing. He was measuring, with, his eye, the distance the
+balloon had yet to go and also the distance away the motor-boat was
+from where it would probably land.
+
+"He can do it!" exclaimed the young inventor.
+
+"How?" asked his father.
+
+For answer Tom caught up a newspaper he had purchased at the hotel that
+morning. Rolling it quickly into a cone, so that it formed a rough
+megaphone, he put the smaller end to his mouth, and, pointing the
+larger opening at the balloonist, he called out:
+
+"Drop into the lake! We'll pick you up before the bag falls on you!
+Jump! Let go now!"
+
+The balloonist heard and understood. So did Ned and Mr. Swift. Tom's
+quick wit had found a way to save the man.
+
+Faster and faster the blazing bag settled toward the surface of the
+water. It was now merely a mushroom-shaped piece of burning and
+smoking canvas, yet it was supporting the man almost as a parachute
+would have done.
+
+With one look upward to the burning mass above him and a glance
+downward to the lake, the aeronaut let go his hold. Like a shot he
+came down, holding his body rigid and straight as a stick, for he knew
+how to fall into water, did that balloonist.
+
+Tom Swift was ready for him. No sooner had the lad called his
+directions through the megaphone than the young inventor had speeded up
+his engine to the top notch.
+
+"Steer so as to pick him up!" Tom cried to Ned, who was at the wheel.
+"Pass by him on a curve, and, as soon as I grab him, put the wheel over
+so as to get out from under the balloon."
+
+It was a risky thing to do, but our hero had it all planned out. He
+made a loop of the boat's painter, and, hurrying to the bow, leaned
+over as far as he could, holding the rope in readiness. His idea was
+to have the balloonist grab the strands and be pulled out of danger by
+the speedy motor-boat, for the blazing canvas would cover such an
+extent of water that the man could not have swum out of the danger zone
+in time.
+
+Down shot the balloonist and down more slowly settled the collapsed
+bag, yet not so slowly that there was any time to spare. It needed
+only a few seconds to drop over the performer, to burn and smother him.
+
+Into the water splashed the man, disappearing from sight as when a
+stick is dropped in, point first. Ned was alert and steered the boat
+to the side in which the man's face was, for he concluded that the
+aeronaut would strike out in that direction when he came up. The ARROW
+was now directly under the blazing balloon and cries of fear from the
+watchers on shore urged upon Tom and his companions the danger of their
+position. But they had to take some risk to rescue the man.
+
+"There he is!" cried Mr. Swift, who was on the watch, leaning over the
+side of the boat. Tom and Ned saw him at the same instant. Ned
+shifted his wheel and the young inventor bent over, holding out the
+rope for the man to grasp. He saw it and struck out toward the ARROW.
+But there was no need for him to go far. An instant more and the
+speeding motor-boat shot past him. He grabbed the rope and Tom, aided
+by Mr. Swift, began to lift him out of the water.
+
+"Quick! To one side, Ned!" yelled Tom, for the heat of the descending
+mass of burning canvas struck him like a furnace blast.
+
+Ned needed no urging. With a swirl of the screw the ARROW shot herself
+out of the way, carrying the aeronaut with her. A moment later the
+burning balloon, or what there was left of it, settled down into the
+lake, hissing angrily as the fire was quenched by the water and
+completely covering the spot where, but a few seconds before, the man
+had been swimming. He had been saved in the nick of time.
+
+
+
+
+CHAPTER XXIII
+
+PLANS FOR AN AIRSHIP
+
+
+"Slow her down, Ned!" cried Tom, for the ARROW was shooting so swiftly
+through the water that the young inventor found it impossible to pull
+up the balloonist. Ned hurried back to the motor, and, when the boat's
+way had been checked, it was an easy matter to pull the dripping and
+almost exhausted man into the craft.
+
+"Are you much hurt?" asked Mr. Swift anxiously, for Tom was too much
+out of breath with his exertion to ask any questions. For that matter
+the man was in almost as bad a plight. He was breathing heavily, as
+one who had run a long race.
+
+"I--I guess I'm all right," he panted. "Only burned a little on my
+hands. That--that was a close call!"
+
+The boat swung around and headed for shore, on which was quite a throng
+of persons. Some of them had cheered when they saw the plucky rescue.
+
+"I'm afraid we can't save your balloon," gasped Tom as he looked at the
+place where the canvas was still floating and burning.
+
+"No matter. It wasn't worth much. That's the last time I'll ever go
+up in a hot-air balloon," said the man with more energy than he had
+before exhibited. "I'm done with 'em. I've had my lesson. Hereafter
+an aeroplane or a gas balloon for me. I only did this to oblige the
+fair committee. I'll not do it again."
+
+The man spoke in short, crisp sentences, as though he was in too much
+of a hurry to waste his words.
+
+"Let it sink," he went on. "It's no good. Glad to see the last of it."
+
+Almost as he spoke, with a final hiss and a cloud of steam that mingled
+with the black smoke, the remains of the big bag sunk beneath the
+surface of the lake.
+
+"We must get you ashore at once and to a doctor," said Mr. Swift. "You
+must be badly burned."
+
+"Not much. Only my hands, where some burning pieces of canvas fell on'
+em. If I had a little oil to put on I'd be all right."
+
+"I can fix you up better than that," put in Tom. "I have some
+Vaseline."
+
+"Good! Just the thing. Pass it over," and the man, though he spoke
+shortly, seemed grateful for the offer. "My name's Sharp," he went on,
+"John Sharp, of no place in particular, for I travel all over. I'm a
+professional balloonist. Ha! That's the stuff!"
+
+This last was in reference to a bottle of Vaseline, which Tom produced.
+Mr. Sharp spread some over the backs of his hands and went on:
+
+"That's better. Much obliged. I can't begin to thank you for what you
+did for me--saved my life. I thought it was all up with me--would have
+been but for you. Mustn't mind my manner--it's a way I have--have to
+talk quick when you're balloonin'--no time--but I'm grateful all the
+same. Who might you people be?"
+
+Tom told him their names and Mr. Swift asked the aeronaut if he was
+sure he didn't need the services of a physician.
+
+"No doctor for me," answered the balloonist. "I've been in lots of
+tight places, but this was the worst squeeze. If you'll put me ashore,
+I guess I can manage now."
+
+"But you're all wet," objected Tom. "Where will you go? You need some
+other clothes," for the man wore a suit of tights and spangles.
+
+"Oh, I'm used to this," went on the performer. "I frequently have to
+fall in the water. I always carry a little money with me so as to get
+back to the place where I started from. By the way, where am I?"
+
+"Opposite Daleton," answered Tom. "Where did you go up from?"
+
+"Pratonia. Big fair there. I was one of the features."
+
+"Then you're about fifteen miles away," commented Mr. Swift. "You can
+hardly get back before night. Must you go there?"
+
+"Left my clothes there. Also a valuable gas balloon. No more hot-air
+ones for me. Guess I'd better go back," and the aeronaut continued to
+speak in his quick, jerky sentences.
+
+"We'd be very glad to have you come with us, Mr. Sharp," went on the
+inventor. "We are not far from Shopton, and if you would like to
+remain over night I'm sure we would make you comfortable. You can
+proceed to Pratonia in the morning."
+
+"Thanks. Might not be a bad idea," said Mr. Sharp. "I'm obliged to
+you. I've got to go there to collect my money, though I suppose they
+won't give it all to me."
+
+"Why not?" demanded Ned.
+
+"Didn't drop from my parachute. Couldn't. Fire was one
+reason--couldn't reach the parachute, and if I could have, guess it
+wouldn't have been safe. Parachute probably was burned too. But I'm
+done with hot-air balloons though I guess I said that before."
+
+The boys were much interested in the somewhat odd performer, and, on
+his part, he seemed to take quite a notion to Tom, who told him of
+several things that he had invented. "Well," remarked Mr. Swift after a
+while, during which the boat had been moving slowly down the lake, "if
+we are not to go ashore for a doctor for you, Mr. Sharp, suppose we put
+on more speed and get to my home? I'm anxious about a robbery that
+occurred there," and he related some facts in the case.
+
+"Speed her up!" exclaimed Mr. Sharp. "Wish I could help you catch the
+scoundrels, but afraid I can't--hands too sore," and he looked at his
+burns. Then he told how he had made the ascension from the Pratonia
+fair grounds and how, when he was high in the air, he had discovered
+that the balloon was on fire. He described his sensations and told how
+he thought his time had surely come. Sparks from the hot air used to
+inflate it probably caused the blaze, he said.
+
+"I've made a number of trips," he concluded, "hot air and gas bags, but
+this was the worst ever. It got on my nerves for a few minutes," he
+added coolly.
+
+"I should think it would," agreed Tom as he speeded up the motor and
+sent the ARROW on her homeward way.
+
+The boys and Mr. Swift were much interested in the experiences of the
+balloonist and asked him many questions, which he answered modestly.
+Several hours passed and late that afternoon the party approached
+Shopton.
+
+"Here we are!" exclaimed Mr. Swift, relief in his tones. "Now to see
+of what I have been robbed and to get the police after the scoundrels!"
+
+When the boat was nearing the dock Mr. Sharp, who had been silent for
+some time, suddenly turned to Tom and asked:
+
+"Ever invent an airship?"
+
+"No," replied the lad, somewhat surprised. "I never did."
+
+"I have," went on the balloonist. "That is, I've invented part of it.
+I'm stuck over some details. Maybe you and I'll finish it some day.
+How about it?"
+
+"Maybe," assented Tom, who was occupied just then in making a good
+landing. "I am interested in airships, but I never thought I could
+build one."
+
+"Easiest thing in the world," went on Mr. Sharp, as if it was an
+everyday matter. "You and I will get busy as soon as we clear up this
+robbery." He talked as though he had been a friend of the family for
+some time, for he had a genial, taking manner.
+
+A little later Mr. Swift was excitedly questioning Garret Jackson
+concerning the robbery and making an examination of the electrical shop
+to discover what was missing.
+
+"They've taken some parts of my gyroscope!" he exclaimed, "and some
+valuable tools and papers, as well as some unfinished work that will be
+difficult to replace."
+
+"Much of a loss?" asked Mr. Sharp with a business-like air.
+
+"Well, not so large as regards money," answered the inventor, "but they
+took things I can never replace, and I will miss them very much if I
+cannot get them back."
+
+"Then we'll get them back!" snapped the balloonist, as if that was all
+there was to it.
+
+The police were called up on the telephone and the facts given to them,
+as well as a description of the stolen things. They promised to do
+what they could, but, in the light of past experiences, Tom and his
+father did not think this would be much. There was little more that
+could be done that evening. Ned Newton went to his home, and, after
+Mr. Swift had insisted in calling in his physician to look after Mr.
+Sharp's burns the balloonist was given a room next to Tom's. Then the
+Swift household settled down.
+
+"Well," remarked Tom to his father, as he got ready for bed, "this sure
+has been an exciting day."
+
+"And my loss is a serious one," added the inventor somewhat sadly.
+
+"Don't worry, dad," begged his son. "I'll do my best to recover those
+things for you."
+
+Several days passed, but there was no clew to the thieves. That they
+were the same ones who had stolen the turbine model there was little
+doubt, but they seemed to have covered their tracks well. The police
+were at a loss, and, though Tom and Mr. Sharp cruised about the lake,
+they could get no trace of the men. The balloonist had sent to
+Pratonia for his clothing and other baggage and was now installed in
+the Swift home, where he was invited to stay a week or two.
+
+One night when he was looking over some papers he had taken from his
+trunk the balloonist came over to where Tom was making a drawing of a
+new machine he was planning and said:
+
+"Like to see my idea for an airship? Different from some. It's a
+dirigible balloon with an aeroplane front and rear to steer and balance
+it in big winds. It would be a winner, only for one thing. Maybe you
+can help me."
+
+"Maybe I can," agreed Tom, who was at once interested.
+
+"We ought to be able to do something. Look at our names--Swift and
+Sharp--quick and penetrating--a good firm to build airships," and he
+laughed genially. "Shall we do it?"
+
+"I'm willing," agreed Tom, and the balloonist spread his plans out on
+the table, he and the young inventor soon being deep in a discussion of
+them.
+
+
+
+
+CHAPTER XXIV
+
+THE MYSTERY SOLVED
+
+
+From then on, for several days, the young inventor and his new friend
+lived in an atmosphere of airships. They talked them from morning
+until night, and even Mr. Swift, much as he was exercised over his
+loss, took part in the discussions.
+
+In the meanwhile efforts had not ceased to locate the robbers and
+recover the stolen goods, but so far without success.
+
+One afternoon, about two weeks after the thrilling rescue of John
+Sharp, Tom said to the balloonist:
+
+"Wouldn't you like to come for a ride in the motor-boat? Maybe it will
+help us to solve the puzzle of the airship. We'll take a trip across
+and up the opposite shore."
+
+"Good idea," commented Mr. Sharp. "Fine day for a sail. Come on.
+Blow the cobwebs from our brains."
+
+Mr. Swift declined an invitation to accompany them, as he said he would
+stay home and try to straighten out his affairs, which were somewhat
+muddled by the robbery.
+
+Out over the blue waters of Lake Carlopa shot the ARROW. It was making
+only moderate speed, as Tom was in no hurry, and he knew his engine
+would last longer if not forced too frequently. They glided along,
+crossed the lake and were proceeding up the opposite shore when, as
+they turned out from a little bay and rounded a point of land, Mr.
+Sharp exclaimed:
+
+"Look out, Tom, there's rowboat just ahead!"
+
+"Oh, I'll pass well to one side of that," answered the young inventor,
+looking at the craft. As he did so, noting that there were four men in
+it, one of the occupants caught a glimpse of the ARROW. No sooner had
+he done so than he spoke to his companions, and they all turned to
+stare at Tom. At first the lad could scarcely believe his eyes, but as
+he looked more intently he uttered a cry.
+
+"There they are!"
+
+"Who?" inquired Mr. Sharp.
+
+"Those men--the thieves! We must catch them!"
+
+Tom had spoken loudly, but even though the men in the rowboat did hear
+what he said, they would have realized without that that they were
+about to be pursued, for there was no mistaking the attitude of our
+hero.
+
+Two of the thieves were at the oars, and, with one accord, they at once
+increased their speed. The boat swung about sharply and was headed for
+the shore, which they seemed to have come from only a short time
+previous, as the craft was not far out in the lake.
+
+"No, you don't!" cried Tom. "I see your game! You want to get to the
+woods, where you'll have a better chance to escape! If this isn't
+great luck, coming upon them this way!"
+
+It was the work of but a moment to speed up the engine and head the
+ARROW for the rowboat. The men were pulling frantically, but they had
+no chance.
+
+"Get between them and the shore!" cried Mr. Sharp. "You can head them
+off then." This was good advice and Tom followed it. The men, among
+whom the lad could recognize Happy Harry and Anson Morse, were all
+excited. Two of them stood up, as though to jump overboard, but their
+companions called to them to stop.
+
+"If we only had a gun now, not to shoot at them but to intimidate
+them," murmured the balloonist, "maybe they'd stop."
+
+"Here's one," answered Tom, pointing to the seat locker, where he kept
+the shotgun Mr. Duncan had given him. In a moment Mr. Sharp had it out.
+
+"Surrender!" he cried, pointing the weapon at the men in the small boat.
+
+"Don't shoot! Don't fire on us! We'll give up!" cried Happy Harry,
+and the two with the oars ceased pulling.
+
+"Don't take any chances," urged Mr. Sharp in a low voice. "Keep
+between them and the shore. I'll cover them." Tom was steering from
+an auxiliary side wheel near the motor, and soon the ARROW had cut off
+the retreat of the men. They could not land and to row across the lake
+meant speedy capture.
+
+"Well, what do you want of us?" growled Morse. "What right have you
+got to interfere with us in this fashion?"
+
+"The best of right," answered Tom. "You'll find out when you're landed
+in jail."
+
+"You can't arrest us," sneered Happy Harry. "You're not an officer and
+you haven't any warrant."
+
+Tom hadn't thought of that, and his chagrin showed in his face. Happy
+Harry was quick to see it.
+
+"You'd better let us go," he threatened "We can have you arrested for
+bothering us. You haven't any right to stop us, Tom Swift."
+
+"Maybe he hasn't, but I have!" exclaimed John Sharp suddenly.
+
+"You! Who are you?" demanded Featherton, alias Simpson, the man who
+had run the automobile that carried Tom away.
+
+"Me. I'm a special deputy sheriff for this county," answered the
+balloonist simply. "Here's my badge," and, throwing back his coat, he
+displayed it. "You see I got the appointment in order to have some
+authority in the crowds that gather to watch me go up," he explained to
+Tom, who plainly showed his astonishment. "I found it very useful to
+be able to threaten arrest, but in this case I'll do more than
+threaten. You are my prisoners," he went on to the men in the boat,
+and he handled the shotgun as if he knew how to use it. "I'll take you
+into custody on complaint of Mr. Swift for robbery. Now will you go
+quietly or are you going to make a fuss?" and Mr. Sharp shut his jaw
+grimly.
+
+"Well, seeing as how you have the drop on us, I guess we'll have to do
+as you say," admitted Happy Harry, alias Jim Burke. "But you can't
+prove anything against us. We haven't any of Mr. Swift's property."
+
+"Well, you know where it is then," retorted Tom quickly.
+
+Under the restraining influence of the gun the men made no resistance.
+While Mr. Sharp covered them, Tom towed their boat toward shore. Then,
+while the young inventor held the gun, the balloonist tied the hands
+and feet of the thieves in a most scientific manner, for what he did
+not know about ropes and knots was not worth putting into a book.
+
+"Now, I guess they'll stay quiet for a while," remarked Mr. Sharp as he
+surveyed the crestfallen criminals. "I'll remain on guard here, Tom,
+while you go notify the nearest constable and we'll take them to jail.
+We bagged the whole lot as neatly as could be desired."
+
+"No, you didn't get all of us!" exclaimed Happy Harry, and there was a
+savage anger in his tones.
+
+"Keep quiet!" urged Morse.
+
+"No, I'll not keep quiet! It's a shame that we have to take our
+medicine while that trimmer, Tod Boreck, goes free. He ought to have
+been with us, and he would be, only he's trying to get away with that
+sparkler!"
+
+"Keep quiet," again urged Morse.
+
+Tom was all attention. He had caught the word "sparkler," and he at
+once associated it with the occasion he had heard the men use it
+before. He felt that he was on the track of solving the mystery
+connected with his boat.
+
+He looked at the men. They were the same four who had been involved in
+the former theft--Appleson, Featherton, Morse and Burke. Were there
+five of them? He recalled the man who had been caught tampering with
+his boat--the man who had tried to bid on the ARROW at the auction.
+Where was he?
+
+"Boreck didn't get what he was after," resumed Happy Harry, "and I'm
+going to spoil his game for him. Say, kid," he went on to Tom, "look
+in the front part of your boat--where the gasoline tank is."
+
+Tom felt his heart beating fast. At last he felt that he would solve
+the puzzle. He opened the forward compartment. To his disappointment
+it seemed as usual. Morse and the others were making a vain effort to
+silence Happy Harry.
+
+"I don't see anything here," said Tom.
+
+"No, because it's hidden in one of those blocks of wood you use for a
+brace," continued the man. "Which one it is, Boreck didn't know, so he
+pulled out two or three, only to be fooled each time. You must have
+shifted them, kid, from the way they were when we had the boat."
+
+"I did," answered the young inventor, recollecting how he had taken out
+some of the braces and inserted new ones, then painted the interior of
+the compartment. "What is in the braces, anyhow?"
+
+"The sparkler--a big diamond--in a hollow place in the wood, kid!"
+exclaimed Happy Harry, blurting out the words. "I'm not going to let
+Tod Boreck get away with it while we stay in jail."
+
+"Take out all the braces that haven't been moved and have a look,"
+suggested Mr. Sharp. Tom only had to remove two, those farthest back,
+for all the others had, at one time or another, been changed or taken
+away by the thief.
+
+One of the blocks did not seem to have anything unusual about it, but
+at the sight of the other Tom could not repress a cry. It was the one
+that seemed to have had a hole bored in it and then plugged up again.
+He remembered his father noticing it on the occasion of overhauling the
+boat.
+
+"The sparkler's in there," said the tramp as he saw the brace. "Boreck
+was after it several times, but he never pulled out the right one."
+
+With his knife Tom dug out the putty that covered the round hole in the
+block. No sooner had he done so than there rolled out into his hand a
+white object. It was something done up in tissue paper, and as he
+removed the wrapper, there was a flash in the sunlight and a large,
+beautiful diamond was revealed. The mystery had been solved.
+
+
+
+
+CHAPTER XXV
+
+WINNING A RACE
+
+
+"Where did this diamond come from?" demanded Mr. Sharp of the quartette
+of criminals.
+
+"That's for us to know and you to find out," sneered Happy Harry. "I
+don't care as long as that trimmer Boreck didn't get it. He tried to
+do us out of our share."
+
+"Well, I guess the police will make you tell," went on the balloonist.
+"Go for the constable, Tom."
+
+Leaving his friend to guard the ugly men, who for a time at least were
+beyond the possibility of doing harm, Tom hurried off through the woods
+to the nearest village. There he found an officer and the gang was
+soon lodged in jail. The diamond was turned over to the authorities,
+who said they would soon locate the owner.
+
+Nor were they long in doing it, for it appeared the gem was part of a
+large jewel robbery that had taken place some time before in a distant
+city. The Happy Harry gang, as the men came to be called, were
+implicated in it, though they got only a small share of the plunder.
+Search was made for Tod Boreck and he was captured about a week after
+his companions. Seeing that their game was up, the men made a partial
+confession, telling where Mr. Swift's goods had been secreted, and the
+inventor's valuable tools, papers and machinery were recovered, no
+damage having been done to them.
+
+It developed that after the diamond theft, and when the gang still had
+possession of Mr. Hastings' boat, Boreck, sometimes called Murdock by
+his cronies, unknown to them, had secreted the jewel in one of the
+braces under the gasoline tank. He expected to get it out secretly,
+but the capture of the gang and the sale of the boat prevented this.
+Then he tried to buy the craft to take out the diamond, but Tom overbid
+him. It was Boreck who found Andy's bunch of keys and used one to open
+the compartment lock when Tom surprised him. The man did manage to
+remove some of the blocks, thinking he had the one with the diamond in
+it, but the fact of Tom changing them, and painting the compartment
+deceived him. The gang hoped to get some valuables from Mr. Swift's
+shops, and, to a certain extent, succeeded after hanging around for
+several nights and following him to Sandport, but Tom eventually proved
+too much for them. Even stealing the Arrow, which was taken to aid the
+gang in robbing Mr. Swift, did not succeed, and Boreck's plan then to
+get possession of the diamond fell through.
+
+It was thought that the gang would get long terms in prison, but one
+night, during a violent storm, they escaped from the local jail and
+that was the last seen of them for some time.
+
+A few days after the capture as Tom was in the boathouse making some
+minor repairs to the motor he heard a voice calling:
+
+"Mistah Swift, am yo' about?"
+
+"Hello, Rad, is that you?" he inquired, recognizing the voice of the
+colored owner of the mule Boomerang.
+
+"Yais, sa, dat's me. I got a lettah fo' yo'. I were passin' de
+post-office an' de clerk asted me to brung it to yo' 'case as how it's
+marked 'hurry,' an' he said he hadn't seen yo' to-day."
+
+"That's right. I've been so busy I haven't had time to go for the
+mail," and Tom took the letter, giving Eradicate ten cents for his
+trouble.
+
+"Ha, that's good!" exclaimed Tom as he read it.
+
+"Hab some one done gone an' left yo' a fortune, Mistah Swift?" asked
+the negro.
+
+"No, but it's almost as good. It's an invitation to take part in the
+motor-boat races next week. I'd forgotten all about them. I must get
+ready."
+
+"Good land! Dat's all de risin' generation t'inks about now," observed
+Eradicate, "racin' an' goin' fast. Mah ole mule Boomerang am good
+enough fo' me," and, shaking his head in a woeful manner, Eradicate
+went on his way.
+
+Tom told Mr. Sharp and his father of the proposed races of the Lanton
+Motor-boat Club, and, as it was required that two persons be in a craft
+the size of the ARROW, the young inventor arranged for the balloonist
+to accompany him. Our hero spent the next few days in tuning up his
+motor and in getting the ARROW ready for the contest.
+
+The races took place on that side of Lake Carlopa near where Mr.
+Hastings lived, and he was one of the officials of the club. There
+were several classes, graded according to the horsepower of the motors,
+and Tom found himself in a class with Andy Foger.
+
+"Here's where I beat you," boasted the red-haired youth exultantly,
+though his manner toward Tom was more temperate than usual. Andy had
+learned a lesson.
+
+"Well, if you can beat me I'll give you credit for it," answered Tom.
+
+The first race was for high-powered craft, and in this Mr. Hastings'
+new CARLOPA won. Then came the trial of the small boats, and Tom was
+pleased to note that Miss Nestor was on hand in the tiny DOT.
+
+"Good luck!" he called to her as he was adjusting his timer, for his
+turn would come soon. "Remember what I told you about the spark," for
+he had given her a few lessons.
+
+"If I win it will be due to you," she called brightly.
+
+She did win, coming in ahead of several confident lads who had better
+boats. But Miss Nestor handled the DOT to perfection and crossed the
+line a boat's length ahead of her nearest competitor.
+
+"Fine!" cried Tom, and then came the warning gun that told him to get
+ready for his trial.
+
+This was a five-mile race and had several entrants. The affair was a
+handicap one and Tom had no reason to complain of the rating allowed
+him.
+
+"Crack!" went the starting pistol and away went Tom and one or two
+others who had the same allowance as did he. A little later the others
+started and finally the last class, including Andy Foger. The RED
+STREAK shot ahead and was soon in the lead, for Andy and Sam had
+learned better how to handle their craft. Tom and Mr. Sharp were
+worried, but they stuck grimly to the race and when the turning stake
+was reached Tom's motor had so warmed up and was running so well that
+he crept up on Andy. A mile from the final mark Andy and Tom were on
+even terms, and though the red-haired lad tried to shake off his rival
+he could not. Andy's ignition system failed him several times and he
+changed from batteries to magneto and back again in the hope of getting
+a little more speed out of the motor.
+
+But it was not to be. A half-mile away from the finish Tom, who had
+fallen behind a little, crept up on even terms. Then he slowly forged
+ahead, and, a hundred rods from the stake, the young inventor knew that
+the race was his. He clinched it a few minutes later, crossing the
+line amid a burst of cheers. The ARROW had beaten several boats out of
+her own class and Tom was very proud and happy.
+
+"My, but we certainly did scoot along some!" cried Mr. Sharp. "But
+that's nothing to how we'll go when we build our airship, eh, Tom?" and
+he looked at the flushed face of the lad.
+
+"No, indeed," agreed the young inventor. "But I don't know that we'll
+take part in any races in it. We'll build it, however, as soon as we
+can solve that one difficulty."
+
+They did solve it, as will be told in the next book of this series, to
+be called "Tom Swift and His Airship; or, The Stirring Cruise of the
+RED CLOUD." They had some remarkable adventures in the wonderful
+craft, and solved the mystery of a great bank robbery.
+
+This ended the contests of the motor-boats and the little fleet crowded
+up to the floats and docks, where the prizes were to be awarded. Tom
+received a handsome silver cup and Miss Nestor a gold bracelet.
+
+"Now I want all the contestants, winners and losers, to come up to my
+house and have lunch," invited Mr. Hastings.
+
+As Tom and the balloonist strolled up the walk to the handsome house
+Andy Foger passed them.
+
+"You wouldn't have beaten me if my spark coil hadn't gone back on me,"
+he said, somewhat sneeringly.
+
+"Maybe," admitted Tom, and just then he caught sight of Mary Nestor.
+"May I take you in to lunch?" he asked.
+
+"Yes," she said, "because you helped me to win," and she blushed
+prettily. And then they all sat down to the tables set out on the
+lawn, while Tom looked so often at Mary Nestor that Mr. Sharp said
+afterward it was a wonder he found time to eat. But Tom didn't care.
+He was happy.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4

+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including including checks, online payments and credit card
+donations. To donate, please visit: https://pglaf.org/donate

+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
