Tom had a number of adventures on the wheel, and, after having used the motor to save a valuable patent model from a gang of unscrupulous men, the lad acquired possession of a power boat, in which he made several trips, and took part in many exciting happenings.

Some time later, in company with John Sharp, an aeronaut, whom Tom had rescued from Lake Carlopa, after the airman had nearly lost his life in a burning balloon, the young inventor made a big airship, called the Red Cloud.With Mr.Damon, Tom made several trips in this craft, as set forth in the book, "Tom Swift and His Airship."It was after this that Tom and his father built a submarine boat, and went under the ocean for sunken treasure, and, following that trip Tom built a speedy electric runabout, and by a remarkable run in that, with Mr.Damon, saved a bank from ruin, bringing gold in time to stave off a panic."Tom Swift and His Wireless Message" told of the young inventor's plan to save the castaways of Earthquake Island, and how he accomplished it by constructing a wireless plant from the remains of the wrecked airship Whizzer.After Tom got back from Earthquake Island he went with Mr.Barcoe Jenks, whom he met on the ill-fated bit of land, to discover the secret of the diamond makers.They found the mysterious men, but the trip was not entirely successful, for the mountain containing the cave where the diamonds were made was destroyed by a lightning shock, just as Mr.Parker, a celebrated scientist, who accompanied the party, said it would be.But his adventure in seeking to discover the secret of making precious stones did not satisfy Tom Swift, and when he and his friends got back from the mountains they prepared to go to Alaska to search for gold in the caves of ice.They were almost defeated in their purpose by the actions of Andy Foger and his father, who in an under-hand manner, got possession of a valuable map, showing the location of the gold, and made a copy ofthe drawing.

Then, when Tom and his friends set off in the Red Cloud, as related in "Tom Swift in the Caves of Ice," the Fogers, in another airship, did likewise.But Tom and his party were first on the scene, and accomplishedtheir purpose, though they had to fight the savage Indians.The airship was wrecked in a cave of ice, that collapsed on it, and the survivors had desperate work getting away from the frozen North.

Tom had been home all the following winter and spring, and he had done little more than work on some small inventions, when a new turn was given his thoughts and energies by a visit from Mr.Gunmore, as narrated in the first chapter of the present volume."Well, I guess no one is here," remarked the young inventor as he completed the circuit of the grounds and walked slowly back toward the house."I think I scared Andy so that he won't come back right away.He had the laugh on me, though, when I stumbled and fell."As Tom proceeded he heard some one approaching, around the path at the side of the house.

"Who's there?" he called quickly, taking a firmer grasp of his stick, "It's me, Massa Swift," was the response."I jest come back from town.

I got some peppermint fo' mah mule, Boomerang, dat's what I got." "Oh! It's you, is it, Rad?" asked the youth in easier tones."Dat's who it am, Did yo' t'ink it were some un else?""I did," replied Tom."Andy Foger has been sneaking around.Keep your eyes open the rest of the night, Rad.""I will, Massa Tom."

The youth went into the house, having left word with the engineer, Mr.Jackson, to be on the alert for anything suspicious.

"And now I guess I'll go to bed, and make an early start to-morrow morning, planning my new aeroplane," mused Tom."I'm going to make the speediest craft of the air ever seen!"As he started toward his room Tom Swift heard the voice of the housekeeper calling to him:

"Tom! Oh, Tom! Come here, quickly!" "What's the matter?" he asked, in vague alarm.

"Something has happened to your father!" was the startling reply."He's fallen down, and is Unconscious! Come quickly! Send for the doctor!"Tom fairly ran toward his father's room.
