"Come on, Dad! Something has happened!" yelled Tom, dashing from the shop, followed by his parent. They found themselves in the midst of a rain storm, as they raced toward the house, on the roof of which the smashing noise was again heard. CHAPTER II MR. DAMON'S STEERING Tom Swift was a lad of action, and his quickness in hurrying out to investigate what had happened when he was explaining about his new battery, was characteristic of him. Those of my readers who know him, through having read the previous books of this series, need not be told this, but you who, perhaps, are just making his acquaintance, may care to know a little more about him. As told in my first book, "Tom Swift and His Motor-Cycle" the young inventor lived with his father, Barton Swift, a widower, in the town of Shopton, New York. Mr. Swift was also an inventor of note. In my initial volume of this series, Tom became possessed of a motor-cycle in a peculiar way. It was sold to him by a Mr. Wakefield Damon, a wealthy gentleman who was unfortunate in riding it. On his speedy machine, which Tom improved by several inventions, he had a number of adventures. The principal one was being attacked by a number of bad men, known as the "Happy Harry Gang," who wished to obtain possession of a valuable turbine patent model belonging to Mr. Swift. Tom was taking it to a lawyer, when he was waylaid, and chloroformed. Later he traced the gang, and, with the assistance of Mr. Damon and Eradicate Sampson, an aged colored man who made a living for himself and his mule, Boomerang, by doing odd jobs, the lad found the thieves and recovered a motor-boat which had been stolen. But the men got away. In the second volume, called "Tom Swift and His Motor-Boat," Tom bought at auction the boat stolen by, and recovered from, the thieves, and proceeded to improve it. While he was taking his father out on a cruise for Mr. Swift's health, the Happy Harry Gang made a successful attempt to steal some valuable inventions from the Swift house. Tom started to trace them, and incidentally he raced and beat Andy Foger, a rich bully. On their way down the lake, after the robbery, Tom, his father and Ned Newton, Tom's chum, saw a man hanging from the trapeze of a blazing balloon over Lake Carlopa. The balloonist was Mr. John Sharp and he was rescued by Tom in a thrilling fashion. In his motor-boat, Tom had much pleasure, not the least of which was taking out a young lady named Miss Mary Nestor, whose acquaintance he had made after stopping her runaway horse, which his bicycle had frightened. Tom's association with Miss Nestor soon ripened into something deeper than mere friendship.
