The Boy Inventors and the Vanishing Gun

Jack Chadwick stepped from the door of the shed where he and Tom Jesson, his cousin—and, like Jack, about seventeen years old—had been busy all the morning getting the Flying Ro...

Mr. Peregrine, having alighted from his Red Hawk, removed his helmet and goggles and mopped his forehead vigorously—for the day was warm, it being about the middle of August. Th...

As he reached the door, clouds of blue smoke met him. The vapor almost choked him. Whoever was tampering with the motor had neglected to pay much attention to the lubricating de...

“Oh, it was, was it?” sputtered Zack furiously, regarding the remnants of his craft, “well, you just mind your own business. If it hadn’t been for you coming along and spying on...

Jack and Tom sped along on their way to Nestorville pleasantly enough, but just as they were entering the little town there came a sudden ominous cracking sound from the rear of...

It rained in torrents all that night; but by dawn the sky had cleared, and a bright sun shone warmly. But everywhere about High Towers were plentiful evidences of the abundance...

It was decided after a brief consultation not to deflate the gas bag and drop to earth, but to fly straight on to Pokeville. Jack knew the direction in a general way, and kept t...

During the trip from Westerlo to Pokeville the case of Ralph Ingersoll had been discussed in all its bearings, and it had been decided that, for the present at any rate, he was...

But the fellow kept on without turning his head. He was evidently making for a lane which ran at the rear of Mr. Peregrine’s grounds. But a high fence separated him from it, a f...

Although there was no necessity for great speed, the boys were anxious to get their errand accomplished and deposit the model safely in Boston. Then, too, Jack was looking forwa...

Less than five minutes later the approaching automobile swept into view. The boys felt rather uneasy when they saw it, for they knew it instantly to be the identical yellow mach...

“Not much of a one, though,” he hastened to say, “but it’s the best I can think of right now. Those fellows must have gone a short way up this wood road after putting up that si...

Jack flung the words back as he leaped forward and stumbled against the bottom step of a flight of stairs. Higher up he could hear his quarry scuttling off in the darkness like...

It was the next morning in Mr. Bowler’s office, and that man of the law was seated at his desk with Tom Jesson beside him. Tom had just finished telling of the events of the pre...

“Not very far, that is, by itself,” rejoined Tom instantly; “you see this automatic steerer would only keep it on the road on a straight course. It couldn’t help it to negotiate...

Just then recollection rushed back with the force of the incoming tide. The boy recalled how he had followed Jake Rook up the stairs of the tenement house, how he had crossed th...

It is now time to return to the bedside of Ralph Ingersoll, in the home of Dr. Tallman. It was evening and Tom, as he had promised, had returned to hear Ralph’s story and see wh...

Tom did more rapid-fire thinking right then that he had ever done in his life before. Bitterly he blamed himself, too, for halting the car at Jake Rook’s request. If only he had...

In an office on lower Wall Street, New York, overlooking the East River with its bustle of water traffic, sat Stephen Melville, the man to whom Rook’s message had been addressed...

Tom’s fall was not a long one. But he was bruised and shaken by it. Had it not been for the fact that he had tumbled into what had been an old mushroom cellar that was floored w...

Dr. Tallman was standing on his porch the next morning. By his side was Ralph, pale and a bit shaky, but with a glad look on his face. The news of Jack’s safety had heartened hi...

In the livery stable on Emmons Street, the same one in which Ralph had been confined, sat four men. They were grouped about a table in a small room in the rear of the place, for...

Captain Andrews burst into the hotel a short time later like a bombshell, scattering bell-boys and guests in his mad rush to reach Jack and Tom, who were awaiting him in a corne...

“Just this, that a bird in the hand is worth two in the bush,” declared the stout old seaman. “Maybe they did land the model in the night; but in that case what are they doing a...
