+by Victor Appleton
+
+August, 2000 [Etext #2273]
+
+
+**The Project Gutenberg Etext of Tom Swift And His Motor-Boat**
+*****This file should be named 02tom10.txt or 02tom10.zip******
+
+Corrected EDITIONS of our etexts get a new NUMBER, 02tom11.txt.
+VERSIONS based on separate sources get new LETTER, 02tom10a.txt.
+
+
+The Etext was prepared for Project Gutenberg by Ronald Benninghoff
+And proof read by Erin Hartshorn and George Joseph
+
+
+We are now trying to release all our books one month in advance
+of the official release dates, for time for better editing.
+
+Please note: neither this list nor its contents are final till
+midnight of the last day of the month of any such announcement.
+The official release date of all Project Gutenberg Etexts is at
+Midnight, Central Time, of the last day of the stated month. A
+preliminary version may often be posted for suggestion, comment
+and editing by those who wish to do so. To be sure you have an
+up to date first edition [xxxxx10x.xxx] please check file sizes
+in the first week of the next month. Since our ftp program has
+a bug in it that scrambles the date [tried to fix and failed] a
+look at the file size will have to do, but we will try to see a
+new copy has at least one byte more or less.
+
+
+Information about Project Gutenberg (one page)
+
+We produce about two million dollars for each hour we work. The
+fifty hours is one conservative estimate for how long it we take
+to get any etext selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. This
+projected audience is one hundred million readers. If our value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour this year as we release thirty-two text
+files per month: or 400 more Etexts in 1996 for a total of 800.
+If these reach just 10% of the computerized population, then the
+total should reach 80 billion Etexts.
+
+The Goal of Project Gutenberg is to Give Away One Trillion Etext
+Files by the December 31, 2001. [10,000 x 100,000,000=Trillion]
+This is ten thousand titles each to one hundred million readers,
+which is only 10% of the present number of computer users. 2001
+should have at least twice as many computer users as that, so it
+will require us reaching less than 5% of the users in 2001.
+
+
+We need your donations more than ever!

+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 bad 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 I 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,
+to 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 wart 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 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 weather 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' 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 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 dandy 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.

+
+
+**The Project Gutenberg Etext of Tom Swift And His Motor-Boat**
+*****This file should be named 02tom10.txt or 02tom10.zip******
+
+Corrected EDITIONS of our etexts get a new NUMBER, 02tom11.txt.
+VERSIONS based on separate sources get new LETTER, 02tom10a.txt.
+
+
+The Etext was prepared for Project Gutenberg by Ronald Benninghoff
+And proof read by Erin Hartshorn and George Joseph
+
+
+We are now trying to release all our books one month in advance
+of the official release dates, for time for better editing.
+
+Please note: neither this list nor its contents are final till
+midnight of the last day of the month of any such announcement.
+The official release date of all Project Gutenberg Etexts is at
+Midnight, Central Time, of the last day of the stated month. A
+preliminary version may often be posted for suggestion, comment
+and editing by those who wish to do so. To be sure you have an
+up to date first edition [xxxxx10x.xxx] please check file sizes
+in the first week of the next month. Since our ftp program has
+a bug in it that scrambles the date [tried to fix and failed] a
+look at the file size will have to do, but we will try to see a
+new copy has at least one byte more or less.
+
+
+Information about Project Gutenberg (one page)
+
+We produce about two million dollars for each hour we work. The
+fifty hours is one conservative estimate for how long it we take
+to get any etext selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. This
+projected audience is one hundred million readers. If our value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour this year as we release thirty-two text
+files per month: or 400 more Etexts in 1996 for a total of 800.
+If these reach just 10% of the computerized population, then the
+total should reach 80 billion Etexts.
+
+The Goal of Project Gutenberg is to Give Away One Trillion Etext
+Files by the December 31, 2001. [10,000 x 100,000,000=Trillion]
+This is ten thousand titles each to one hundred million readers,
+which is only 10% of the present number of computer users. 2001
+should have at least twice as many computer users as that, so it
+will require us reaching less than 5% of the users in 2001.

+<h2>CHAPTER I</h2>
+
+<h2>A MOTOR-BOAT AUCTION</h2>
+
+<p>"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."</p>
+
+<p>"So I have, dad. I'm going over to Lanton."</p>
+
+<p>"To Lanton? What for?"</p>
+
+<p>"I want to have a look at that motor-boat."</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"Oh, yes, I remember now. But what is the boat doing over at
+Lanton?"</p>
+
+<p>"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&mdash;"</p>
+
+<p>"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."</p>
+
+<p>"No, dad, I only&mdash;"</p>
+
+<p>"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?"</p>
+
+<p>"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&mdash;"</p>
+
+<p>"But you wouldn't buy a damaged boat, would you?"</p>
+
+<p>"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&mdash;or it was when it was new."</p>
+
+<p>"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.</p>
+
+<p>"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&mdash;"</p>
+
+<p>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.</p>
+
+<p>"Would you really like to make a bid on that boat Tom?" he asked.</p>
+
+<p>"Would I, dad? Well&mdash;" The youth did not finish, but his father
+knew what he meant.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>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?"</p>
+
+<p>"Would you consider a hundred and fifty dollars too high?"</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"What's the matter?" asked his father, who had started toward one
+of several machine shops on the premises&mdash;shops where Mr. Swift
+and his son did inventive work.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>About the same time that Tom bought the motor-cycle a firm of
+rascally lawyers, Smeak &amp; 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.</p>
+
+<p>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 &amp;
+Crawford, of Washington, attorneys for Mr. Swift. Mr. Crawford
+had an errand in Albany and had agreed to meet Tom there with the
+model.</p>
+
+<p>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.</p>
+
+<p>Tom was thinking of the exciting scenes he had passed through
+about a month previous as he spun along the road leading to
+Lanton.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>"Go ahead, bump him!" the young inventor heard Sam whisper.</p>
+
+<p>"You'd better try it, if you want to get the best trouncing you
+ever had!" cried Tom hotly.</p>
+
+<p>"Hu! I s'pose you think you're going to bid on the boat?" sneered
+Andy.</p>
+
+<p>"Is there any law against it?" asked Tom.</p>
+
+<p>"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."</p>
+
+<p>"All right," answered Tom non-committally. "Go ahead. It's a
+free country."</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+
+<h2>CHAPTER II</h2>
+
+<h2>SOME LIVELY BIDDING</h2>
+
+<p>"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:</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>All eyes were turned on Tom, for many knew him.</p>
+
+<p>"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?"</p>
+
+<p>"Keep quiet," begged Sam Snedecker. "People are laughing at you,
+Andy."</p>
+
+<p>"I don't care if they are," muttered the sandy haired youth. "Tom
+Swift needn't think he's everything."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Guess he can't be much interested in the motor," decided Tom.</p>
+
+<p>"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&mdash;
+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.</p>
+
+<p>"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?"</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>No one would, and the auctioneer descended to three hundred, then
+to two and finally, as if impatient, he called out:</p>
+
+<p>"Well, will any one start at fifty dollars?"</p>
+
+<p>Instantly there were several cries of "I will!"</p>
+
+<p>"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?"</p>
+
+<p>"Sixty!" called out Andy Foger in a shrill voice. Several turned
+to look at him.</p>
+
+<p>"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."</p>
+
+<p>"Sixty I'm bid, sixty&mdash;sixty!" cried Mr. Wood in a sing-song
+tone, "who'll make it seventy?"</p>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>"Here, who's bidding above me?" exclaimed Andy, as if it was
+against the law.</p>
+
+<p>"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?"</p>
+
+<p>"Well, I offered sixty," said the squint-eyed bully, while his
+crony, Sam Snedecker, was vainly, pulling at his sleeve.</p>
+
+<p>"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?"</p>
+
+<p>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&mdash;seventy I'm bid. Will any one make it eighty?"</p>
+
+<p>"Eighty!" exclaimed Andy Foger after a whispered conference with
+Sam. "I know as much about boats as Tom Swift. I'll make it
+eighty."</p>
+
+<p>"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&mdash;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&mdash;"</p>
+
+<p>"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.</p>
+
+<p>"Ninety!" called out the auctioneer.</p>
+
+<p>"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.</p>
+
+<p>"One hundred!" called Andy, as if no one would dare go above that.</p>
+
+<p>"I'm offered an even hundred," resumed Mr. Wood. "We are
+certainly coming on. A hundred I am bid, a hundred&mdash;a hundred&mdash;a
+hundred&mdash;"</p>
+
+<p>"And five," said the strange man hastily, and he seemed to choke
+as he uttered the words.</p>
+
+<p>"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.</p>
+
+<p>"That's queer," murmured Tom. "I guess that was his limit, yet if
+he wanted the boat badly that wasn't a high price."</p>
+
+<p>"Who's going ahead of me?" demanded Andy in loud tones.</p>
+
+<p>"Keep quiet!" urged Sam. "We may get it yet."</p>
+
+<p>"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?"</p>
+
+<p>Tom wondered why the man bad 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.</p>
+
+<p>"A hundred and twenty-five!" he called out.</p>
+
+<p>"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?"</p>
+
+<p>Andy and Sam seemed to be having some dispute.</p>
+
+<p>"Let's make him quit right now," suggested Andy in a hoarse
+whisper.</p>
+
+<p>"You can't," declared Sam'</p>
+
+<p>"Yes, I can. I'll go up to my limit right now."</p>
+
+<p>"And some one will go above you&mdash;-maybe Tom will," was Sam's
+retort.</p>
+
+<p>"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."</p>
+
+<p>Tom heard what was said, but did not reply. The auctioneer was
+calling monotonously: "I'm bid a hundred and twenty-five&mdash;twenty-five.
+Will any one make it fifty?"</p>
+
+<p>"A hundred and fifty!" sang out Andy, and all eyes were directed
+toward him.</p>
+
+<p>"Sixty!" said Tom quietly.</p>
+
+<p>"Here, you&mdash;" began the red-haired lad. You&mdash;"</p>
+
+<p>"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."</p>
+
+<p>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:</p>
+
+<p>"I'll give a hundred and seventy-five dollars for that boat!"</p>
+
+<p>"Good!" cried the auctioneer. "That's the way to talk. I'm
+offered a hundred and seventy-five."</p>
+
+<p>"Eighty," said Tom quietly, though his heart was beating fast.</p>
+
+<p>"Well, of all&mdash;" began Andy, but Sam Snedecker dragged him back.</p>
+
+<p>"You haven't got any more money," said the bully's crony.
+"Better stop now."</p>
+
+<p>"I will not! I'm going home for more," declared Andy. "I must
+have that boat."</p>
+
+<p>"It will be sold when you get back," said Sam.</p>
+
+<p>"Haven't you got any money you can lend me?" inquired the squint-eyed
+one, scowling in Tom's direction.</p>
+
+<p>"No, not a bit. There, some one raised Tom's bid."</p>
+
+<p>At that moment a man in the crowd offered a hundred and eighty-one
+dollars.</p>
+
+<p>"Small amounts thankfully received," said Mr. Wood with a laugh.
+Then the bidding became lively, a number making one-dollar
+advances.</p>
+
+<p>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.</p>
+
+<p>"Two hundred dollars!" he called boldly.</p>
+
+<p>"I'm offered two hundred!" repeated Mr. Wood. "That is something
+like it. Now who will raise that?"</p>
+
+<p>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.</p>
+
+<p>"Two hundred&mdash;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&mdash;twice&mdash;three times. Two hundred dollars. Going&mdash;going&mdash;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."</p>
+
+<p>There was a laugh as Tom, blushingly, advanced. He passed Andy
+Foger, who had worked his way over near him.</p>
+
+<p>"You got the boat," sneered the bully, "and I s'pose you think you
+got ahead of me."</p>
+
+<p>"Keep quiet!" begged Sam.</p>
+
+<p>"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!"</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+
+<h2>CHAPTER III</h2>
+
+<h2>A TIMELY WARNING</h2>
+
+<p>"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.</p>
+
+<p>"Oh, yes, I calculated to pay just what I did."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"So you got my boat," remarked the former owner of the craft. "I
+hope you will be able to fix it up."</p>
+
+<p>"Oh, I think I shall," answered the new owner of the CARLOPA. "If
+I can't, father will help me."</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"That's a good idea. Call it the Swift."</p>
+
+<p>"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&mdash;"</p>
+
+<p>"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."</p>
+
+<p>"Not in the least," said Tom. "Don't you want the letters from
+each side of the bow to put on your new craft?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"What's the matter?" asked Mr. Hastings.</p>
+
+<p>"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.</p>
+
+<p>"Who is he?" asked Mr. Hastings, while Tom started on a run toward
+the boat.</p>
+
+<p>"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.</p>
+
+<p>"Did he do any damage?" asked Mr. Hastings.</p>
+
+<p>"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?"</p>
+
+<p>"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?"</p>
+
+<p>"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?"</p>
+
+<p>"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.</p>
+
+<p>"Nothing in there he could want," commented the former owner of
+the craft.</p>
+
+<p>"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.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"Certainly, as long as you like."</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"Hold on, dar I Hold on, Mistah Swift!" cried a colored man,
+suddenly popping into view. "Doan't go down dat hill."</p>
+
+<p>"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?"</p>
+
+<p>"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!"</p>
+
+<p>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.</p>
+
+<p>"How'd the log get across the road, Rad?" asked Tom.</p>
+
+<p>"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."</p>
+
+<p>"I took it for a short cut," said the lad. "Come on, let's take a
+look at the log."</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>"Does yo' t'ink dat, Mistah Swift?" asked Eradicate, his eyes
+getting big.</p>
+
+<p>"I certainly do, and, if you hadn't warned me, I might have been
+killed."</p>
+
+<p>"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."</p>
+
+<p>"I'm glad you did warn me," went on the youth solemnly. Then, as
+he went closer to the log, he uttered an exclamation.</p>
+
+<p>"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."</p>
+
+<p>Something on the ground caught Tom's eye. He stooped and picked
+up a nickle-plated wrench.</p>
+
+<p>"This may come in handy as evidence," he murmured.</p>
+
+
+<h2>CHAPTER IV</h2>
+
+<h2>TOM AND ANDY CLASH</h2>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"Maybe some one done it to make yo' hab trouble, Mistah Swift."</p>
+
+<p>"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&mdash;"</p>
+
+<p>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."</p>
+
+<p>"Which way did dat auto go?" resumed Eradicate.</p>
+
+<p>"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.</p>
+
+<p>"Den if it's down heah, maybe we cotch 'em," suggested the colored
+man.</p>
+
+<p>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:</p>
+
+<p>"Here's the auto, Rad!"</p>
+
+<p>The colored man ran up, his eyes wider open than ever. There,
+hidden amid the bushes, was a large touring car.</p>
+
+<p>"Whose am dat?" asked Eradicate.</p>
+
+<p>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!"</p>
+
+<p>"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&mdash;road&mdash;hill&mdash;logs!" stammered Andy, turning
+red under his freckles.</p>
+
+<p>"That's what I said," replied Tom coolly.</p>
+
+<p>"I&mdash;I didn't have anything to do with putting a log across any
+road," mumbled the bully. "I&mdash;I've been off toward the creek."</p>
+
+<p>"Have you?" asked Tom with a peculiar smile.</p>
+
+<p>"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&mdash;I told him
+not to do it!" exclaimed Sam as he came from his hiding place.</p>
+
+<p>"Shut up!" exclaimed Andy desperately.</p>
+
+<p>"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!"</p>
+
+<p>"You haven't got any evidence against us," sneered Andy
+confidently, his old bravado coming back.</p>
+
+<p>"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,
+to don't think you're going to escape."</p>
+
+<p>"You get out of my automobile!" demanded Andy. "I'll have you
+arrested if you don't."</p>
+
+<p>"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."</p>
+
+<p>"S'pose I won't do it?" snapped Andy.</p>
+
+<p>"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."</p>
+
+<p>"Don't you dare touch me!" cried the bully, but there was a whine
+in his tones.</p>
+
+<p>"You let me alone or I'll tell my father!" added Sam. "I&mdash;I
+didn't have nothin' to do with it, anyhow. I told Andy it would
+make trouble, but he made me help him."</p>
+
+<p>"Say, what's the matter with you?" demanded Andy indignantly of
+his crony. "Do you want to&mdash;"</p>
+
+<p>"I wish I'd never come with you," went on Sam, who was beginning
+to be frightened.</p>
+
+<p>"Come now. Start up that machine and haul the log out of the
+way," demanded Tom again.</p>
+
+<p>"I won't do it!" retorted the red-haired lad impudently.</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER V</h2>
+
+<h2>A TEST OF SPEED</h2>
+
+<p>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:</p>
+
+<p>"You just wait, Tom Swift! You just wait!"</p>
+
+<p>"Well, I'm waiting," responded the other calmly.</p>
+
+<p>"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!"</p>
+
+<p>"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.</p>
+
+<p>"I&mdash;I ain't gone' to do nothin'," declared Sam.</p>
+
+<p>"I told Andy not to put that tree&mdash;"</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"I'm goin' to take it away!" growled Andy. "Give a fellow a show
+can't you?"</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"'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&mdash;eradicatin' dirt.
+Much obleeged, I'll call around. Giddap, Boomerang!"</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"Of course I will. Do you think you can get any speed out of it?"</p>
+
+<p>"Well, I'm not so anxious for speed. I wart 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."</p>
+
+<p>"What is it?" asked the inventor, his rather tired face lighting
+up with interest.</p>
+
+<p>"I'm going to take you on a vacation trip."</p>
+
+<p>"A vacation trip?"</p>
+
+<p>"Yes, you need a rest. You've been working, too hard over that
+gyroscope invention."</p>
+
+<p>"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 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."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"Very well, then you won't be in any danger from Andy Foger. I
+must speak to his father about him."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"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!"</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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:</p>
+
+<p>"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!"</p>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>"Yes '. I'm here," admitted Tom with a laugh.</p>
+
+<p>"And in a motor-boat, too! Bless my pocketbook, but did that run
+away with some one who sold it to you cheap?"</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"I'll come some day," promised the lad.</p>
+
+<p>"Bless my hat band, but I hope so," went on the eccentric
+individual as he prepared to start his car.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"The tank will not vibrate so when I'm going at full speed," he
+explained to his father.</p>
+
+<p>"Is that where the strange man was tampering with the lock the day
+of the auction?" asked Mr. Swift.</p>
+
+<p>"Yes, but I don't see what he could want in this compartment, do
+you dad?"</p>
+
+<p>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:</p>
+
+<p>"Did you bore that hole in there, Tom?"</p>
+
+<p>"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."</p>
+
+<p>"No, I suppose not. I was just wondering weather that was one of
+the new blocks or an old one."</p>
+
+<p>"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."</p>
+
+<p>"I think that's a good idea," commented Mr. Swift.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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:</p>
+
+<p>"Something's coming behind us."</p>
+
+<p>Tom turned his head and looked. Then he called out:</p>
+
+<p>"It's Mr. Hastings in his new CARLOPA. I wonder if he wants a
+race?"</p>
+
+<p>"Guess he'd have it all his own way," suggested Ned.</p>
+
+<p>"Oh, I don't know. I can get a little more speed out of my boat."</p>
+
+<p>Tom waited until the former owner of the ARROW was up to him.</p>
+
+<p>"Want a race?" asked Mr. Hastings good-naturedly.</p>
+
+<p>"Sure!" agreed Tom, and he shoved the timer ahead to produce
+quicker explosions.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"She certainly is a dandy!" declared Ned. "I wish I had one like
+it."</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"Water rat," he murmured, "or maybe muskrats. I must set some
+traps."</p>
+
+<p>As Tom entered the boathouse he started back in alarm, for a
+bright light flashed up, almost in his eyes.</p>
+
+<p>"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.</p>
+
+<p>"Hold on there!" cried the young inventor. "Who are you? What do
+you want? Come back here!"</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+
+<h2>CHAPTER VI</h2>
+
+<h2>TOWING SOME GIRLS</h2>
+
+<p>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.</p>
+
+<p>"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&mdash;"</p>
+
+<p>The idea of fire was in Tom's mind, and he did not finish his
+half-completed thought.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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."</p>
+
+<p>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.</p>
+
+<p>As our hero passed a boat, containing three very pretty young
+ladies, Tom heard one of them exclaim:</p>
+
+<p>"There he is now! That's Tom Swift."</p>
+
+<p>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:</p>
+
+<p>"Well, have you caught any more runaway horses lately?"</p>
+
+<p>"Runaway horses&mdash;why&mdash;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.</p>
+
+<p>"So you've given up the bicycle for the motor-boat," went on the
+young lady.</p>
+
+<p>"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."</p>
+
+<p>The two boats had drifted close together, and Miss Nestor
+introduced her two companions to Tom.</p>
+
+<p>"Don't you want to come in and take a ride?" he asked.</p>
+
+<p>"Is it safe?" asked Jennie Haddon, one of the trio.</p>
+
+<p>"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."</p>
+
+<p>"What will we do with our boat?" asked Katie Carson.</p>
+
+<p>"Oh, I can tow that," replied the youth. "Get right in and I'll
+take you all around the lake."</p>
+
+<p>"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."</p>
+
+<p>"Maybe Mr. Swift will come and have some lunch with us," suggested
+Miss Carson, blushing prettily.</p>
+
+<p>"Nothing would give me greater pleasure," answered Tom, and then
+he laughed at his formal reply, the girls joining in.</p>
+
+<p>"We'd be glad to have you," added Miss Haddon. "Oh!" she suddenly
+screamed, "the boat's tipping over!"</p>
+
+<p>"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."</p>
+
+<p>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:</p>
+
+<p>"Oh, mister, give us a ride!"</p>
+
+<p>"Sure!" agreed Tom pleasantly. "Just fasten your boat to the
+other rowboat and I'll tow you."</p>
+
+<p>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.</p>
+
+<p>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:</p>
+
+<p>"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."</p>
+
+<p>"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:</p>
+
+<p>"Oh, girls, it's lunch time! We must go ashore. Will you kindly
+put about, Mr. Swift&mdash;I hope that is the proper term&mdash;and&mdash;land
+us&mdash;is that right?" and she looked archly at Tom.</p>
+
+<p>"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.</p>
+
+<p>"And come yourself to take lunch with us, added Miss Haddon.</p>
+
+<p>"I'm afraid I might be in the way," stammered Tom. "I&mdash;I have a
+pretty good appetite, and&mdash;"</p>
+
+<p>"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.</p>
+
+<p>"Yes, and I'd like to have him explain over again how the engine
+works," went on Miss Haddon. "I am so interested."</p>
+
+<p>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.</p>
+
+<p>"Now come right over this way to our table," invited Miss Nestor.
+"I want you to meet papa and mamma."</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER VII</h2>
+
+<h2>A BRUSH WITH ANDY</h2>
+
+<p>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.</p>
+
+<p>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?"</p>
+
+<p>"Yes," replied Tom, "I did&mdash;er&mdash;that is&mdash;" He paused in some
+confusion.</p>
+
+<p>"Perhaps you'd like&mdash;-that is prefer&mdash;to go with them instead of
+taking lunch with girls who don't know anything about engines?"
+she persisted.</p>
+
+<p>"Oh, no indeed," Tom hastened to assure her. "He&mdash;that is&mdash;the
+person I saw wouldn't care to have me lunch with him," and the
+youth smiled grimly.</p>
+
+<p>"Would you like to bring him over to our table?" inquired Miss
+Carson. "We have plenty for him."</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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:</p>
+
+<p>"Hold on there, Andy Foger, I want to see you!" and there was
+menace in Tom's tone.</p>
+
+<p>"But, I don't want to see you!" retorted the other sulkily. "I've
+got no use for you."</p>
+
+<p>"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&mdash;"</p>
+
+<p>"My keys! Your boat! On fire!" gasped Andy, so plainly
+astonished that Tom knew his surprise was genuine.</p>
+
+<p>"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.</p>
+
+<p>Andy Foger advanced slowly. He took the bunch of keys and looked
+at the tag.</p>
+
+<p>"They are mine," he said slowly, as if there was some doubt about
+it.</p>
+
+<p>"Of course they are," declared Tom. "I found them where you
+dropped them&mdash;in my boat."</p>
+
+<p>"Do you mean over at the auction?"</p>
+
+<p>"No, I mean down in my boathouse, where you sneaked in the other
+night and tried to do some damage.</p>
+
+<p>"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."</p>
+
+<p>"Didn't you sneak in my boathouse the other night and try to do
+some mischief? Didn't you drop them then?"</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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' 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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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?"</p>
+
+<p>"I don't know, unless you found them, kept them and dropped them
+there," was the insolent answer.</p>
+
+<p>"You know better than that," exclaimed Tom.</p>
+
+<p>"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.</p>
+
+<p>"I don't want your money!" fired back Tom.</p>
+
+<p>"But I'd like to know who it was that was in my boat."</p>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Maybe that's Mr. Hastings," thought Tom. "If I raced with him
+now, I think the ARROW could give a better account of herself."</p>
+
+<p>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&mdash;a red-haired,
+squint-eyed chap.</p>
+
+<p>"Andy Foger!" exclaimed Tom. "He's got a motor-boat! This is the
+surprise he spoke of."</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>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:</p>
+
+<p>"Yes, I'll race you. Where to?"</p>
+
+<p>"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."</p>
+
+<p>"I don't need any start," declared Tom. "I'll race you on even
+terms. Go ahead!"</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER VIII</h2>
+
+<h2>OFF ON A TRIP</h2>
+
+<p>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.</p>
+
+<p>"I'll be giving you a tow in a few minutes, as soon as my engine
+gets warmed up!" sneered Andy.</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Come on!" cried the red-haired lad. "I thought you wanted a
+race."</p>
+
+<p>"I do," answered the young inventor. "We're a long way from the
+dock yet, and we've got to come back."</p>
+
+<p>"You'll be out of it by the time I get to the dock," declared
+Andy.</p>
+
+<p>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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>The two boats were now on even terms and were racing along side by
+side toward the wooded, point, which marked the finish.</p>
+
+<p>"I'll beat you yet!" exclaimed Andy fiercely.</p>
+
+<p>"Better hurry up!" retorted Tom.</p>
+
+<p>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?"</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>Mr. Swift was much interested that night in his son's account of
+the race.</p>
+
+<p>"I had no idea yours was such a speedy boat," he said.</p>
+
+<p>"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?"</p>
+
+<p>"Somewhat, Tom. I can't seem to hit on just what I want. It's a
+difficult problem."</p>
+
+<p>"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."</p>
+
+<p>"What will you do, Tom?"</p>
+
+<p>"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?"</p>
+
+<p>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.</p>
+
+<p>"I think I will accept," said the inventor with a smile. "When
+can you start, Tom?"</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"What's the matter?" asked Ned.</p>
+
+<p>"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."</p>
+
+<p>"Much harm done?" asked Ned anxiously.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Maybe the block fell out," suggested Ned.</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>A little later the ARROW was puffing away up the lake in the
+direction of Sandport.</p>
+
+
+<h2>CHAPTER IX</h2>
+
+<h2>MR. SWIFT IS ALARMED</h2>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"That's the way to talk!" cried the son. "Your appetite is
+improving, too. If Mrs. Baggert could see you she'd say so."</p>
+
+<p>"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.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"Well, I guess Garret and Mrs. Baggert will look out for them,"
+remarked his son. "Don't worry."</p>
+
+<p>"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."</p>
+
+<p>"Nothing the matter with your appetite, either," commented the
+young inventor as he passed the coffee pot and the plate.</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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:</p>
+
+<p>"I shouldn't be surprised if it rained to-morrow, Ned."</p>
+
+<p>"Me either. It does look sort of hazy, and the wind is in a bad
+quarter."</p>
+
+<p>"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."</p>
+
+<p>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:</p>
+
+<p>"S'pose that's Andy looking for another race?"</p>
+
+<p>"No, the boat's too small for his. We'll put over that way and
+see who it is."</p>
+
+<p>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.</p>
+
+<p>"That machine isn't working right," he remarked to his chum.</p>
+
+<p>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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"How comes it that you are up here?" went on Tom.</p>
+
+<p>"I am stopping with friends, who have a cottage near the Lakeview
+Hotel. They have a motor-boat and I got Dick Blythe&mdash;he's the
+owner of this&mdash;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&mdash;or something dreadful
+happened."</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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&mdash;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.</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"Good idea," commented Tom.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>"No, Tom, it's not the gyroscope that's worrying me."</p>
+
+<p>"What is it then?"</p>
+
+<p>"Those scoundrels are around again, Tom!" and Mr. Swift looked
+apprehensively about him.</p>
+
+<p>"You mean the men who stole the turbine model?"</p>
+
+<p>"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."</p>
+
+<p>"What sort of a man?"</p>
+
+<p>"Well, an ordinary enough individual, but I noticed that he had
+tattooed on the little finger of his left hand a blue ring."</p>
+
+<p>"Happy Harry, the tramp!" exclaimed Tom. "What can he and Morse
+be doing here?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"How, Tom?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+
+<h2>CHAPTER X</h2>
+
+<h2>A CRY FOR HELP</h2>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"Could you hear what they were saying?"</p>
+
+<p>"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."</p>
+
+<p>"Who is Murdock?"</p>
+
+<p>"I don't know, unless he is another member of the gang or unless
+that is an assumed name."</p>
+
+<p>"It may be that. What else did you hear?"</p>
+
+<p>"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&mdash;Happy Harry&mdash;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.</p>
+
+<p>"Sparkler," murmured Tom. "I wonder what that can be?"</p>
+
+<p>"That's a slang word for diamonds," suggested Ned.</p>
+
+<p>"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."</p>
+
+<p>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."</p>
+
+<p>"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.</p>
+
+<p>"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 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."</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>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?"</p>
+
+<p>"No, Tom, of course not, if it will help you any. Do you want me
+to stay here?"</p>
+
+<p>"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."</p>
+
+<p>"Of course I'll stay here at the hotel. This is just as good a
+vacation as I could wish."</p>
+
+<p>"Oh, I don't mean all the while. Just a day or so&mdash;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."</p>
+
+<p>"Then I'll stay, and if I see any of those men&mdash;"</p>
+
+<p>"You'd better steer clear of them," advised Tom quickly. "They
+are dangerous customers."</p>
+
+<p>"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."</p>
+
+<p>"Hold on there!" cried Tom gaily. "No trespassing, you know."</p>
+
+<p>"Oh, I'll just say I'm your agent," promised Ned with a grin.
+"You can't object to that."</p>
+
+<p>"No, I s'pose not. Well, do the best you can. She is certainly a
+nice girl."</p>
+
+<p>"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&mdash;"</p>
+
+<p>"After I start the runaway," interrupted Tom.</p>
+
+<p>"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!"</p>
+
+<p>"Never mind, I'm giving you a show. Now let's get to bed early,
+as I want to get a good start."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Some one's hurt&mdash;shot" cried the youth aloud.</p>
+
+<p>He turned the boat in toward the bank. As he shut off the power
+from the motor he heard the cry again:</p>
+
+<p>"Help! Help! Help!"</p>
+
+<p>"I must go ashore!" he exclaimed. "Probably some one is badly
+wounded by a gun."</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XI</h2>
+
+<h2>A QUICK RUN</h2>
+
+<p>"Where are you?" cried Tom. "Are you hurt? Where are you?"</p>
+
+<p>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.</p>
+
+<p>"Where are you?" cried the lad again. "I've come to help you.
+Where are you?"</p>
+
+<p>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.</p>
+
+<p>Once more the groan sounded and it was followed by a faint voice
+speaking:</p>
+
+<p>"Here I am, under the big oak tree. Oh, whoever you are, help me
+quickly! I'm bleeding to death!"</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"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?"</p>
+
+<p>"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&mdash;your handkerchief
+will do."</p>
+
+<p>The man sighed weakly and his eyes closed again. The lad saw the
+blood spurting from an ugly wound.</p>
+
+<p>"I must make a tourniquet," the youth exclaimed. "That will check
+the bleeding until I can get him to a doctor."</p>
+
+<p>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.</p>
+
+<p>"That's&mdash;that's better," murmured Mr. Duncan. "Now if you can go
+for a doctor&mdash;" He had to pause for breath.</p>
+
+<p>"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?"</p>
+
+<p>"Perhaps&mdash;maybe. I'll be stronger in a moment, now that the
+bleeding has stopped. But not&mdash;not home&mdash;frighten my wife.
+Take me to the sanitarium if you can&mdash;sanitarium up the lake, a
+few miles from here."</p>
+
+<p>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.</p>
+
+<p>"Water&mdash;a drink!" murmured Mr. Duncan.</p>
+
+<p>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.</p>
+
+<p>"Do you think you can get to the boat, if I help you?" asked Tom.</p>
+
+<p>"Yes, I believe so. To think of meeting you again, and under such
+circumstances! It is providential."</p>
+
+<p>"Did someone shoot you?" inquired Tom, who could not get out of
+his head the notion of the men who had once assaulted him.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Do you know where the sanitarium is?" asked the wounded hunter.</p>
+
+<p>"About," answered Tom a little doubtfully, "but I'm afraid it's
+going to be hard to locate it in this fog."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"Guess I'll not run at full speed," decided Tom. "I wouldn't like
+to crash into the RED STREAK. We'd both sink."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"Mr. Duncan," cried Tom, "are you worse?"</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>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&mdash;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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>Mr. Duncan was quickly taken up to the sanitarium on a stretcher
+and Tom followed.</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+
+<h2>CHAPTER XII</h2>
+
+<h2>SUSPICIOUS CHARACTERS</h2>
+
+<p>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.</p>
+
+<p>"Is the injury a bad one?" asked Tom, entering softly.</p>
+
+<p>"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."</p>
+
+<p>"I am glad I chanced to be going past when you called," replied
+the lad.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"Will you do me a favor?" asked Mr. Duncan quickly.</p>
+
+<p>"Of course."</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>"That's perfectly true," she said, showing her white, even teeth.
+"I think, Mr. Swift, I shall have to order you to take them."</p>
+
+<p>"All right," agreed Tom, "only it's too much for what I did."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"This will come in dandy this fall!" he exclaimed. "I'll go
+hunting quail and partridge as well as wild ducks. This compass
+is just what I need, too."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Hello!" exclaimed the young inventor in some alarm. "What's up
+now?"</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"Want a tow?" sneered Andy.</p>
+
+<p>"What'll you take for your second-hand boat that won't run?"
+asked Pete Bailey.</p>
+
+<p>"Better get out of the way or you might be run down," added Sam
+Snedecker.</p>
+
+<p>Tom was too angry and chagrined to reply, and the RED STREAK swept
+on.</p>
+
+<p>"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?"</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"Now for home!" cried Tom, "and if I meet Andy Foger I'll race
+him this time."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Hello, Garret!" exclaimed the lad, taking it for granted it was
+the engineer employed by Mr. Swift.</p>
+
+<p>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.</p>
+
+<p>"Here! Who are you? What do you want?" yelled Tom.</p>
+
+<p>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:</p>
+
+<p>"Happy Harry, the tramp!"</p>
+
+<p>Before he could call again the two men had disappeared.</p>
+
+
+<h2>CHAPTER XIII</h2>
+
+<h2>TOM IN DANGER</h2>
+
+<p>"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!"</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>"Hello! Who's there? Who are you?" called a voice suddenly.</p>
+
+<p>"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!"</p>
+
+<p>"Why if it isn't Tom!" ejaculated the engineer. "However in the
+world did you get here? I thought you were at Sandport."</p>
+
+<p>"I'll explain later, Garret. Just now I want to catch those men,
+if I can."</p>
+
+<p>"Which men?"</p>
+
+<p>"Happy Harry and another one. I saw them hiding down by the
+orchard path. Come on, they're right ahead of us."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"I hardly think so, for they didn't know I was coming."</p>
+
+<p>"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."</p>
+
+<p>"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?"</p>
+
+<p>"Perfectly sure, but you and I will take a look around the shop."</p>
+
+<p>They made a hasty examination, but found nothing disturbed and no
+signs that anyone had tried to break in.</p>
+
+<p>"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."</p>
+
+<p>"I will, Tom. Don't worry."</p>
+
+<p>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.</p>
+
+<p>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:</p>
+
+<p>"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."</p>
+
+<p>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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Get out of the way or we'll run you down!" cried the bully.
+"We've got the right of way."</p>
+
+<p>"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.</p>
+
+<p>Suddenly Andy uttered a cry and leaped up.</p>
+
+<p>"Look out! Look out!" he yelled. "My steering gear has broken!
+I can't change my course. Look out!"</p>
+
+<p>The RED STREAK was bearing right down on Tom's boat.</p>
+
+<p>"Shut off your power! Reverse!" shouted Tom.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"What do you mean by running me down?" shouted Tom angrily.</p>
+
+<p>"I&mdash;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."</p>
+
+<p>"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!"</p>
+
+<p>"I'll pay for the damage," replied Andy, and he was so frightened
+that he was white, in spite of his tan and freckles.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XIV</h2>
+
+<h2>THE ARROW DISAPPEARS</h2>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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:</p>
+
+<p>"The ARROW is gone!"</p>
+
+<p>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.</p>
+
+<p>"That's mighty funny," mused the youth. "I wonder&mdash;"</p>
+
+<p>He paused suddenly in his thoughts.</p>
+
+<p>"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."</p>
+
+<p>This was the one weak point in Tom's theory, and he felt it at
+once.</p>
+
+<p>"I'll see if Garret is in his shop," he went on as he turned back
+toward the house.</p>
+
+<p>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.</p>
+
+<p>"I&mdash;I thought you were out in my boat!" stammered Tom.</p>
+
+<p>"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.</p>
+
+<p>"Because it's gone!"</p>
+
+<p>"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.</p>
+
+<p>"I can't understand it," said Tom helplessly. "I wasn't gone more
+than an hour at dinner, and yet&mdash;"</p>
+
+<p>"It doesn't take long to steal a motor-boat," commented the
+engineer.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"And I'll wager I know who did it," exclaimed Mr. Jackson
+energetically.</p>
+
+<p>"Who?" demanded Tom quickly.</p>
+
+<p>"Those men who were sneaking around&mdash;Happy Harry and his gang.
+They stole the boat once and they'd do it again. Those men took
+your boat, Tom."</p>
+
+<p>The young inventor shook his head.</p>
+
+<p>"No," he answered, "I don't believe they did."</p>
+
+<p>"Why not?"</p>
+
+<p>"Well, because they wouldn't dare come back here when they knew
+we're on the lookout for them. It would be too risky."</p>
+
+<p>"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."</p>
+
+<p>"I don't think so," repeated Mr. Swift's son.</p>
+
+<p>"Who do you think took it then?"</p>
+
+<p>"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&mdash;for outbidding him on this boat.
+He's tried several times, but he hasn't succeeded&mdash;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.</p>
+
+<p>"Where are you going?" asked Mr. Jackson.</p>
+
+<p>"To find Andy and his cronies. When I locate them I'll make them
+tell me where my boat is."</p>
+
+<p>"Hadn't you better send some word to your father? You can hardly
+get to Sandport now, and he'll be worried about you."</p>
+
+<p>"That's so, I will. I'll telephone dad that the boat&mdash;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.</p>
+
+<p>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.</p>
+
+<p>"Now to find Andy and my boat!" Tom exclaimed as he hung up the
+telephone receiver.</p>
+
+
+<h2>CHAPTER XV</h2>
+
+<h2>A DISMAYING STATEMENT</h2>
+
+<p>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.</p>
+
+<p>"What will you do first?" asked Mr. Jackson as he saw his
+employer's son hesitating.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"So it is," exclaimed the lad. "I will use my catboat. I had
+forgotten all about it of late. I'm glad you spoke."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"Did he say where he was going?" asked our hero, who did not tell
+Andy's mother why he wanted to see her son.</p>
+
+<p>"No, and I'm worried about him. Sometimes I think Andy is
+too&mdash;well, too impetuous, and I'm afraid he will get into
+trouble."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"Oh, but I shall tell him," insisted Mrs. Foger with a kind smile.
+"I'm sure he will appreciate your call."</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"Maybe you'd better notify the police," suggested Mr. Jackson when
+Tom returned to the Swift house that night. "They might help
+locate it."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"Suppose they don't?"</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"It's queer that the Foger boy doesn't come home. That makes it
+look as if he was guilty."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"Trouble. What kind of trouble?" asked Tom.</p>
+
+<p>"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."</p>
+
+<p>"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!"</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"That's the RED STREAK as sure as I'm alive!" he cried. "But
+what's the matter with her? They're rowing!"</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>The sailing craft swiftly approached the motor-boat. Tom could see
+the three occupants looking at him, apprehensively as well as
+curiously, he thought.</p>
+
+<p>"Guess they didn't think I'd keep after 'em," mused the young
+inventor, and a little later he was beside the RED STREAK.</p>
+
+<p>"Well," cried Tom angrily, "it's about time you came back!"</p>
+
+<p>"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.</p>
+
+<p>"I've been waiting for you," went on Tom.</p>
+
+<p>"Waiting for us? What for?" asked Sam Snedecker.</p>
+
+<p>"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!"</p>
+
+<p>"Your boat!" repeated the bully, and there was no mistaking the
+surprise in his tones.</p>
+
+<p>"Yes, my boat! Don't try to bluff me like that."</p>
+
+<p>"I'm not trying to bluff you. We've been away, three days and
+just got back."</p>
+
+<p>"Yes, I know you have. You took my boat with you, too."</p>
+
+<p>"Are you crazy?" demanded Pete Bailey.</p>
+
+<p>"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.</p>
+
+<p>"Look here!" burst out Andy, and he spoke sincerely, "we didn't
+touch your boat. Did we, fellows?"</p>
+
+<p>"No!" exclaimed Sam and Pete at once, and they were very much in
+earnest.</p>
+
+<p>"We didn't even know it was stolen, did we?" went on Andy.</p>
+
+<p>"No," agreed his chums. Tom looked unconvinced.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"We haven't seen it since the day we had the collision," added
+Andy, and his chums confirmed this statement.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XVI</h2>
+
+<h2>STILL ON THE SEARCH</h2>
+
+<p>"You seem to have lots of trouble with your boat, Andy," said Tom
+after a few moments of rather embarrassed silence.</p>
+
+<p>"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."</p>
+
+<p>"Suppose I fix it for you?" went on Tom.</p>
+
+<p>"If you do, I'll pay you well."</p>
+
+<p>"I wouldn't do it for pay&mdash;not the kind you mean," continued the
+young inventor.</p>
+
+<p>"What do you mean then?" and Andy's face, that had lighted up,
+became glum again.</p>
+
+<p>"Well, if I fix your boat for you, will you let me run it a little
+while?"</p>
+
+<p>"You mean show me how to run it?"</p>
+
+<p>"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&mdash;"</p>
+
+<p>"And I didn't touch it," interposed the squint-eyed lad quickly.</p>
+
+<p>"All right, I believe you. But somebody stole it, and I think I
+know who."</p>
+
+<p>"Who?" asked Sam Snedecker.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"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?"</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"There," remarked Tom, "now I'm ready to hunt for those
+scoundrels. Will you leave your boat at my dock to-night, Andy?"</p>
+
+<p>"Yes, so you can start out early in the morning. I'm not going."</p>
+
+<p>"Why not?" demanded Tom quickly.</p>
+
+<p>"Well&mdash;er&mdash;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&mdash;"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XVII</h2>
+
+<h2>"THERE SHE IS!"</h2>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"Dinner time," he announced to himself. "Guess I'll run up along
+shore in the shade and eat."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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:</p>
+
+<p>"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!"</p>
+
+<p>"Mr. Damon!" exclaimed Tom, and, without knowing it, he had spoken
+aloud.</p>
+
+<p>"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.</p>
+
+<p>"Here I am, Mr. Damon," answered the lad, stepping out into the
+road. "I knew it was you as soon as I saw you."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Perhaps I can fix it for you as I did before," ventured Tom.</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"Yes, I am after those thieves again."</p>
+
+<p>"In your motor-boat, I presume. Well, I hope you catch them.
+What have they stolen now?"</p>
+
+<p>"My motor-boat. That's why I'm after them, but I had to borrow a
+craft to chase them with."</p>
+
+<p>"Bless my soul! You don't tell me! How did it happen?"</p>
+
+<p>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:</p>
+
+<p>"I don't suppose you have seen anything of the men in my boat,
+have you?"</p>
+
+<p>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:</p>
+
+<p>"Don't say a word now&mdash;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!"</p>
+
+<p>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:</p>
+
+<p>"Bless my shoe buttons!"</p>
+
+<p>"Have you seen them?" asked Tom eagerly.</p>
+
+<p>"Was your boat one with a red arrow painted on the bow?" asked Mr.
+Damon in turn.</p>
+
+<p>"It was!" and the lad was now almost as excited as was his friend.</p>
+
+<p>"Then I've seen it and, what's more, this morning! Bless my spark
+plug, I've seen it!"</p>
+
+<p>"Tell me about it!" pleaded the young inventor, and Mr. Damon,
+calming himself after an effort, resumed:</p>
+
+<p>"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."</p>
+
+<p>"ARROW," corrected Tom.</p>
+
+<p>"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?"</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"Yes!" Tom almost shouted. "But where did they go? What became
+of them? What was the man doing to the forward compartment&mdash;where
+the gasoline tank is?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"Where to?"</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"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?"</p>
+
+<p>"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!"</p>
+
+<p>"I'll be very glad to have you. Go ahead, put the auto in the
+barn and I'll wait for you."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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&mdash;that's the
+question&mdash;why?"</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"Listen!" cried Mr. Damon, who had heard it at the same time.</p>
+
+<p>Tom nodded.</p>
+
+<p>"They're just ahead of us," whispered his companion.</p>
+
+<p>"If it's them," was the lad's reply.</p>
+
+<p>"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?</p>
+
+<p>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.</p>
+
+<p>"There she is!" he cried.</p>
+
+
+<h2>CHAPTER XVIII</h2>
+
+<h2>THE PURSUIT</h2>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"We'll catch them! We'll nab 'em!" he cried. "Speed her up,
+Tom."</p>
+
+<p>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.</p>
+
+<p>"Do you think you can catch them?" asked Mr. Damon anxiously.</p>
+
+<p>"I'm going to make a big try," answered his companion.</p>
+
+<p>"They're heading out into the middle of the lake!" cried the
+eccentric man.</p>
+
+<p>"If they do, I can cut them off!" murmured Tom as he put the wheel
+over.</p>
+
+<p>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.</p>
+
+<p>"A stern chase and a long chase!" murmured Mr. Damon. "Bless my
+rudder, but those fellows are not going to give up easily."</p>
+
+<p>"I guess not," murmured Tom. "Will you steer for a while, Mr.
+Damon?"</p>
+
+<p>"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.</p>
+
+<p>"We're going a bit faster!" called Mr. Damon' encouragingly, "or
+else they're slacking up."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"A pair of marine glasses," cried the lad. "They're trying to
+make out who we are."</p>
+
+<p>"I guess they know well enough," rejoined Mr. Damon. "Can't you
+go any faster, Tom?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"I believe they're going to run ashore and get out!" cried Mr.
+Damon.</p>
+
+<p>"If they do, it's just what I want," declared the lad. "I don't
+care for the men. I want my boat back!"</p>
+
+<p>The occupants of the ARROW were looking to the rear again, and
+one&mdash;Happy Harry, Tom thought&mdash;shook his fist.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Here, don't you damage my boat!" cried Tom involuntarily, for the
+man seemed to be hammering something.</p>
+
+<p>The fellow leaped over the side, holding something in his hand.</p>
+
+<p>"There they go! Catch them!" yelled Mr. Damon.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"I don't doubt it, but my first concern is for my boat. I want to
+see if they have damaged her."</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XIX</h2>
+
+<h2>A QUIET CRUISE</h2>
+
+<p>"Have they done any damage?" asked Mr. Damon as he stood in the
+bow of the RED STREAK.</p>
+
+<p>Tom did not answer for a moment. His trained eye was looking over
+the engine.</p>
+
+<p>"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."</p>
+
+<p>"That's evidently what one man had that the others wanted," was
+Mr. Damon's opinion.</p>
+
+<p>"Probably," agreed Tom. "But what could he or they want with
+wooden braces?"</p>
+
+<p>That was a puzzler for Mr. Damon, but he answered:</p>
+
+<p>"Perhaps they wanted to damage your boat and those two men were
+mad because the other got ahead of them."</p>
+
+<p>"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."</p>
+
+<p>"Good!" exclaimed Mr. Damon. "I'll help you. But can you run
+your boat back home?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"But aren't you going to make a search for those men?" asked Mr.
+Damon when Tom was ready to start back.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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?"</p>
+
+<p>"Yes, I'm glad you reminded me of it. I'll telephone from the
+sanitarium, if they'll let me."</p>
+
+<p>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.</p>
+
+<p>"What are you going to do about your automobile?" asked Tom as
+they neared the point where the machine had been left.</p>
+
+<p>"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."</p>
+
+<p>"Won't you stay all night with me?" invited the young inventor.
+"I'd be glad to have you."</p>
+
+<p>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.</p>
+
+<p>"Did you find your boat?" asked Andy eagerly. "How did the RED
+STREAK run?"</p>
+
+<p>"I got my boat and yours runs fine," explained Tom.</p>
+
+<p>"Good! I'll race you again some day," declared Andy.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>"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."</p>
+
+<p>But Tom could not look ahead. He was destined to have still more
+exciting times, as presently will be related.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"Well, of course we missed you," answered his chum. "But your
+father and I had a good time."</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"Oh, I only just thought of it," said Mr. Swift. "I haven't
+worked the details out yet."</p>
+
+<p>Then he wanted to know about everything at home and he seemed
+particularly anxious lest the Happy Harry gang do some damage.</p>
+
+<p>"I don't believe they will," Tom assured him. "Garret and Mrs.
+Baggert will be on guard."</p>
+
+<p>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.</p>
+
+<p>The three had been out one day and were discussing the necessity
+of returning home soon when Ned spoke.</p>
+
+<p>"I shall hate to give up this life and go to slaving in the bank
+again," he complained. "I wish I was an inventor."</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"Some one has just called you on the telephone, Mr. Swift," he
+reported.</p>
+
+<p>"Some one wants me? Who is it?"</p>
+
+<p>"I think he said his name is Jackson, sir, Garret Jackson, and he
+says the message is very important."</p>
+
+<p>"Tom, something has happened at home!" exclaimed the inventor as
+he hurried up the steps. "I'm afraid there's bad news."</p>
+
+<p>Unable to still the fear in his heart, Tom followed his father.</p>
+
+
+<h2>CHAPTER XX</h2>
+
+<h2>NEWS OF A ROBBERY</h2>
+
+<p>With a hand that trembled so he could scarcely hold the receiver
+of the telephone, Mr. Swift placed it to his ear.</p>
+
+<p>"Hello! Hello!" he cried into the transmitter. "Yes, this is Mr.
+Swift&mdash;yes, Garret. What is it?"</p>
+
+<p>Then came a series of clicks, which Tom and Ned listened to. The
+inventor spoke again.</p>
+
+<p>"What's that? The same men? Broke in early this evening? Oh,
+that's too bad! Of course, I'll come at once."</p>
+
+<p>There followed more meaningless clicks, which Tom wished he could
+translate. His father hung up the receiver, turned to him and
+exclaimed:</p>
+
+<p>"I've been robbed again!"</p>
+
+<p>"Robbed again! How, dad?"</p>
+
+<p>"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!"</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"But just what ones are they? Perhaps we can send out a police
+alarm to-night."</p>
+
+<p>"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."</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"Then we must tell the police at once."</p>
+
+<p>"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."</p>
+
+<p>"I am very sorry, sir. I'll have it ready for you in a few
+minutes."</p>
+
+<p>"All right. Tom, is your boat ready for a quick trip?"</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"Come, Tom," exclaimed the aged inventor impatiently, "we must
+start at once!"</p>
+
+<p>"Won't morning do as well, dad?"</p>
+
+<p>"No, I must start now. I could not sleep worrying over what has
+happened. We will start&mdash;"</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"But I must get home!" insisted Tom's father.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"It's a good thing we didn't start," observed Ned.</p>
+
+<p>"I should say so," agreed Tom. "But we'll get off the first thing
+in the morning, dad."</p>
+
+<p>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,</p>
+
+<p>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.</p>
+
+<p>"Well, Tom, we must start early," he said nervously. "I am glad
+it has cleared off. Is the boat all ready?"</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+
+<h2>CHAPTER XXI</h2>
+
+<h2>THE BALLOON ON FIRE</h2>
+
+<p>Down Lake Carlopa speeded the ARROW, those on board watching the
+banks slip past as the motor-boat rapidly cut through the water.</p>
+
+<p>"What time do you think we ought to reach home, Tom?" asked Mr.
+Swift.</p>
+
+<p>"Oh, about four o'clock, if we don't stop for lunch."</p>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>"We certainly had a good time," remarked Ned. "I don't know when
+I've enjoyed a vacation so."</p>
+
+<p>"It's too bad it had to be cut short by this robbery," commented
+Mr. Swift.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"That's the DOT," he remarked in a low voice to Ned, "Miss
+Nestor's cousin's boat."</p>
+
+<p>"Is she in it now?" asked Ned.</p>
+
+<p>"Yes," answered Tom quickly.</p>
+
+<p>"You've got good eyesight," remarked Ned dryly, "to tell a girl at
+that distance. It looks to me like a boy."</p>
+
+<p>"No, it's Mary&mdash;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.</p>
+
+<p>Ned laughed, Tom blushed still more, and Mr. Swift, who was in a
+stern seat, glanced up quickly.</p>
+
+<p>"It looks as if that boat wanted to hail us," the inventor
+remarked.</p>
+
+<p>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.</p>
+
+<p>"How do you do?" called Miss Nestor, as she slowed down her motor.
+"Don't you think I'm improving, Mr. Swift?"</p>
+
+<p>"What's that? I&mdash;er&mdash;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.</p>
+
+<p>Miss Nestor blushed and looked questioningly at Tom.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"Races? I hadn't heard of them," he replied.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"No, indeed, unless you give me a start of several miles."</p>
+
+<p>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.</p>
+
+<p>"I suppose Andy Foger will enter his boat," commented Ned.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"Look!" he cried, "A balloon! It must have gone up from some
+fair."</p>
+
+<p>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.</p>
+
+<p>"I shouldn't like to be as high as that," remarked Ned.</p>
+
+<p>"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."</p>
+
+<p>"I believe he's going to jump!" suddenly exclaimed Ned after a few
+minutes. "He's going to do something, anyhow."</p>
+
+<p>"Probably come down in a parachute," said Tom. "They generally do
+that."</p>
+
+<p>"No! No!" cried Ned. "He isn't going to jump. Something has
+happened! The balloon is on fire! He'll be burned to death!"</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XXII</h2>
+
+<h2>THE RESCUE</h2>
+
+<p>"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!"</p>
+
+<p>"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."</p>
+
+<p>"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?"</p>
+
+<p>"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.</p>
+
+<p>"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?"</p>
+
+<p>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.</p>
+
+<p>"There, see the parachute!" went on Ned.</p>
+
+<p>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.</p>
+
+<p>"Look! Look!" shouted Tom, bringing his boat to a stop. "That's
+why he can't jump! He can't reach the parachute!"</p>
+
+<p>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.</p>
+
+<p>"Oh, if we could only do something!" cried Tom. "We have to
+remain here helpless and watch him burn to death. It's awful!"</p>
+
+<p>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.</p>
+
+<p>"I thought he was saved then," whispered Tom, and even the whisper
+sounded loud in the silence.</p>
+
+<p>Several men came running along the shore of the lake now. They
+saw the occupants in the ARROW and cried out:</p>
+
+<p>"Why don't you save him? Go to his rescue!"</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"If he does drop, perhaps we may be able to pick him up," said Mr.
+Swift. "I wish we could save him!"</p>
+
+<p>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.</p>
+
+<p>"The balloon is falling apart!" exclaimed Ned. "It's all up with
+him now!"</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"Keep after it, Tom!" urged his father. "We may be able to save
+him!"</p>
+
+<p>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.</p>
+
+<p>"Now he can jump! He's near enough to the water now!" cried Tom.</p>
+
+<p>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.</p>
+
+<p>In such an event he would either be burned to death or so held
+down that drowning must quickly follow.</p>
+
+<p>"If there was only wind enough to carry the balloon beyond him
+after he jumped he could do it safely!" cried Ned.</p>
+
+<p>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.</p>
+
+<p>"He can do it!" exclaimed the young inventor.</p>
+
+<p>"How?" asked his father.</p>
+
+<p>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:</p>
+
+<p>"Drop into the lake! We'll pick you up before the bag falls on
+you! Jump! Let go now!"</p>
+
+<p>The balloonist heard and understood. So did Ned and Mr. Swift.
+Tom's quick wit had found a way to save the man.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"Quick! To one side, Ned!" yelled Tom, for the heat of the
+descending mass of burning canvas struck him like a furnace blast.</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XXIII</h2>
+
+<h2>PLANS FOR AN AIRSHIP</h2>
+
+<p>"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.</p>
+
+<p>"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.</p>
+
+<p>"I&mdash;I guess I'm all right," he panted. "Only burned a little on
+my hands. That&mdash;that was a close call!"</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>The man spoke in short, crisp sentences, as though he was in too
+much of a hurry to waste his words.</p>
+
+<p>"Let it sink," he went on. "It's no good. Glad to see the last
+of it."</p>
+
+<p>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.</p>
+
+<p>"We must get you ashore at once and to a doctor," said Mr. Swift.
+"You must be badly burned."</p>
+
+<p>"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."</p>
+
+<p>"I can fix you up better than that," put in Tom. "I have some
+Vaseline."</p>
+
+<p>"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!"</p>
+
+<p>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:</p>
+
+<p>"That's better. Much obliged. I can't begin to thank you for
+what you did for me&mdash;saved my life. I thought it was all up with
+me&mdash;would have been but for you. Mustn't mind my manner&mdash;it's a
+way I have&mdash;have to talk quick when you're balloonin'&mdash;no
+time&mdash;but I'm grateful all the same. Who might you people be?"</p>
+
+<p>Tom told him their names and Mr. Swift asked the aeronaut if he
+was sure he didn't need the services of a physician.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"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?"</p>
+
+<p>"Opposite Daleton," answered Tom. "Where did you go up from?"</p>
+
+<p>"Pratonia. Big fair there. I was one of the features."</p>
+
+<p>"Then you're about fifteen miles away," commented Mr. Swift. "You
+can hardly get back before night. Must you go there?"</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"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."</p>
+
+<p>"Why not?" demanded Ned.</p>
+
+<p>"Didn't drop from my parachute. Couldn't. Fire was one
+reason&mdash;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."</p>
+
+<p>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.</p>
+
+<p>"Speed her up!" exclaimed Mr. Sharp. "Wish I could help you catch
+the scoundrels, but afraid I can't&mdash;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.</p>
+
+<p>"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.</p>
+
+<p>"I should think it would," agreed Tom as he speeded up the motor
+and sent the ARROW on her homeward way.</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>When the boat was nearing the dock Mr. Sharp, who had been silent
+for some time, suddenly turned to Tom and asked:</p>
+
+<p>"Ever invent an airship?"</p>
+
+<p>"No," replied the lad, somewhat surprised. "I never did."</p>
+
+<p>"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?"</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"Much of a loss?" asked Mr. Sharp with a business-like air.</p>
+
+<p>"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."</p>
+
+<p>"Then we'll get them back!" snapped the balloonist, as if that was
+all there was to it.</p>
+
+<p>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.</p>
+
+<p>"Well," remarked Tom to his father, as he got ready for bed, "this
+sure has been an exciting day."</p>
+
+<p>"And my loss is a serious one," added the inventor somewhat sadly.</p>
+
+<p>"Don't worry, dad," begged his son. "I'll do my best to recover
+those things for you."</p>
+
+<p>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.</p>
+
+<p>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:</p>
+
+<p>"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."</p>
+
+<p>"Maybe I can," agreed Tom, who was at once interested.</p>
+
+<p>"We ought to be able to do something. Look at our names&mdash;Swift
+and Sharp&mdash;quick and penetrating&mdash;a good firm to build
+airships," and he laughed genially. "Shall we do it?"</p>
+
+<p>"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.</p>
+
+
+<h2>CHAPTER XXIV</h2>
+
+<h2>THE MYSTERY SOLVED</h2>
+
+<p>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.</p>
+
+<p>In the meanwhile efforts had not ceased to locate the robbers and
+recover the stolen goods, but so far without success.</p>
+
+<p>One afternoon, about two weeks after the thrilling rescue of John
+Sharp, Tom said to the balloonist:</p>
+
+<p>"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."</p>
+
+<p>"Good idea," commented Mr. Sharp. "Fine day for a sail. Come on.
+Blow the cobwebs from our brains."</p>
+
+<p>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.</p>
+
+<p>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:</p>
+
+<p>"Look out, Tom, there's rowboat just ahead!"</p>
+
+<p>"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.</p>
+
+<p>"There they are!"</p>
+
+<p>"Who?" inquired Mr. Sharp.</p>
+
+<p>"Those men&mdash;the thieves! We must catch them!"</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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!"</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"If we only had a gun now, not to shoot at them but to intimidate
+them," murmured the balloonist, "maybe they'd stop."</p>
+
+<p>"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.</p>
+
+<p>"Surrender!" he cried, pointing the weapon at the men in the small
+boat.</p>
+
+<p>"Don't shoot! Don't fire on us! We'll give up!" cried Happy
+Harry, and the two with the oars ceased pulling.</p>
+
+<p>"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.</p>
+
+<p>"Well, what do you want of us?" growled Morse. "What right have
+you got to interfere with us in this fashion?"</p>
+
+<p>"The best of right," answered Tom. "You'll find out when you're
+landed in jail."</p>
+
+<p>"You can't arrest us," sneered Happy Harry. "You're not an
+officer and you haven't any warrant."</p>
+
+<p>Tom hadn't thought of that, and his chagrin showed in his face.
+Happy Harry was quick to see it.</p>
+
+<p>"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."</p>
+
+<p>"Maybe he hasn't, but I have!" exclaimed John Sharp suddenly.</p>
+
+<p>"You! Who are you?" demanded Featherton, alias Simpson, the man
+who had run the automobile that carried Tom away.</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>"Well, you know where it is then," retorted Tom quickly.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>"No, you didn't get all of us!" exclaimed Happy Harry, and there
+was a savage anger in his tones.</p>
+
+<p>"Keep quiet!" urged Morse.</p>
+
+<p>"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!"</p>
+
+<p>"Keep quiet," again urged Morse.</p>
+
+<p>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.</p>
+
+<p>He looked at the men. They were the same four who had been
+involved in the former theft&mdash;Appleson, Featherton, Morse and
+Burke. Were there five of them? He recalled the man who had been
+caught tampering with his boat&mdash;the man who had tried to bid on
+the ARROW at the auction. Where was he?</p>
+
+<p>"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&mdash;where the gasoline
+tank is."</p>
+
+<p>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.</p>
+
+<p>"I don't see anything here," said Tom.</p>
+
+<p>"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."</p>
+
+<p>"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?"</p>
+
+<p>"The sparkler&mdash;a big diamond&mdash;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."</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+
+<h2>CHAPTER XXV</h2>
+
+<h2>WINNING A RACE</h2>
+
+<p>"Where did this diamond come from?" demanded Mr. Sharp of the
+quartette of criminals.</p>
+
+<p>"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."</p>
+
+<p>"Well, I guess the police will make you tell," went on the
+balloonist. "Go for the constable, Tom."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>A few days after the capture as Tom was in the boathouse making
+some minor repairs to the motor he heard a voice calling:</p>
+
+<p>"Mistah Swift, am yo' about?"</p>
+
+<p>"Hello, Rad, is that you?" he inquired, recognizing the voice of
+the colored owner of the mule Boomerang.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>"Ha, that's good!" exclaimed Tom as he read it.</p>
+
+<p>"Hab some one done gone an' left yo' a fortune, Mistah Swift?"
+asked the negro.</p>
+
+<p>"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."</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"Well, if you can beat me I'll give you credit for it," answered
+Tom.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"If I win it will be due to you," she called brightly.</p>
+
+<p>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.</p>
+
+<p>"Fine!" cried Tom, and then came the warning gun that told him to
+get ready for his trial.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>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.</p>
+
+<p>"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.</p>
+
+<p>"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."</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>"Now I want all the contestants, winners and losers, to come up to
+my house and have lunch," invited Mr. Hastings.</p>
+
+<p>As Tom and the balloonist strolled up the walk to the handsome
+house Andy Foger passed them.</p>
+
+<p>"You wouldn't have beaten me if my spark coil hadn't gone back on
+me," he said, somewhat sneeringly.</p>
+
+<p>"Maybe," admitted Tom, and just then he caught sight of Mary
+Nestor. "May I take you in to lunch?" he asked.</p>
+
+<p>"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.</p>
