"Are you all ready, Tom?" "All ready, Mr. Sharp," replied a young man, who was stationed near some complicated apparatus, while the questioner, a dark man, with a nervous manner, leaned over a large tank. "I'm going to turn on the gas now," went on the man. "Look out for yourself. I'm not sure what may happen."

"Have you anything special to do to-night, Ned?" asked Tom Swift, the well-known inventor, as he paused in front of his chum's window, in the Shopton National Bank. "No, nothing in particular," replied the bank clerk, as he stacked up some bundles of bills. "Why do you ask?"

"Oh Tom, is it really safe?" A young lady-an exceedingly pretty young lady, she could be called-stood with one small, gloved hand on the outstretched wing of an aeroplane, and looked up at a young man, attired in a leather, fur-lined suit, who sat in the cockpit of the machine just above her. "Safe, Mary?" repeated the pilot, as he reached in under the hood of the craft to make sure about one of the controls. "Why, you ought to know by this time that I wouldn't go up if it wasn't safe "

"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?"

Ceasing his restless walk up and down the room, Tom Swift strode to the window and gazed across the field toward the many buildings, where machines were turning out the products evolved from the brains of his father and himself. There was a worried look on the face of the young inventor, and he seemed preoccupied, as though thinking of something far removed from whatever it was his eyes gazed upon.

"What's the matter, Tom? You look rather blue " "Blue Say, Ned, I'd turn red, green, yellow, or any other color of the rainbow, if I thought it would help matters any." "Whew " Ned Newton, the chum and companion of Tom Swift, gave vent to a whistle of surprise, as he gazed at the young fellow sitting opposite him, near a bench covered with strange-looking tools and machinery, while blueprints and drawings were scattered about.

Tom Swift, seated in his laboratory engaged in trying to solve a puzzling question that had arisen over one of his inventions, was startled by a loud knock on the door. So emphatic, in fact, was the summons that the door trembled, and Tom started to his feet in some alarm. "Hello there " he cried. "Don't break the door, Koku " and then he laughed. "No one but my giant would knock like that," he said to himself. "He never does seem able to do things gently. But I wonder why he is knocking. I told him to get the engine out of the airship, and Eradicate said he'd be around to answer the...

"An electric locomotive that can make two miles a minute over a properly ballasted roadbed might not be an impossibility," said Mr. Barton Swift ruminatively. "It is one of those things that are coming," and he flashed his son, Tom Swift, a knowing smile. It had been a topic of conversation between them before the visitor from the West had been seated before the library fire and had sampled one of the elder Swift's good cigars.

"Father," exclaimed Tom Swift, looking up from a paper he was reading, "I think I can win that prize " "What prize is that?" inquired the aged inventor, gazing away from a drawing of a complicated machine, and pausing in his task of making some intricate calculations. "You don't mean to say, Tom, that you're going to have a try for a government prize for a submarine, after all."
