"Bless my calendar!" cried Mr. Damon. "What are you talking about?"
But Tom did not answer, for the reason that just then the Hawk fell into an "air pocket," and needed all his attention to straighten her out and get her on a level course again.
And while Tom Swift is thus engaged in speeding his aircraft along the upper regions toward his home, it will take but a few moments to acquaint my new readers with something of the history of the young inventor. Those who have read the previous books in this series need be told nothing about our hero.
Tom Swift was an inventor of note, as was his father. Mr. Swift was now quite aged and not in robust health, but he was active at times and often aided Tom when some knotty point came up.
Tom and his father lived on the outskirts of the town of Shopton, and near their home were various buildings in which the different machines and appliances were made. Tom's mother was dead, but Mrs. Baggert, the housekeeper, was as careful in looking after Tom and his father as any woman could be.
In addition to these three, the household consisted of Eradicate Sampson, an aged colored servant, and, it might almost be added, his mule Boomerang; but Boomerang had manners that, at times, did not make him a welcome addition to any household. Then there was the giant Koku, one of two big men Tom had brought back with him from the land where the young inventor had been held captive for a time.
The first book of this series is called "Tom Swift and His Motor Cycle," and it was in acquiring possession of that machine that Tom met his friend Mr. Wakefield Damon, who lived in a neighboring town. Mr. Damon owned the motor cycle originally, but when it attempted to climb a tree with him he sold it to Tom.
Tom had many adventures on the machine, and it started him on his inventive career. From then on he had had a series of surprising adventures. He had traveled in his motor boat, in an airship, and then had taken to a submarine. In his electric runabout he showed what the speediest car on the road could do, and when he sent his wireless message, the details of which can be found set down in the volume of that name, Tom saved the castaways of Earthquake Island.
Tom Swift had many other thrilling escapes, one from among the diamond makers, and another from the caves of ice; and he made the quickest flight on record in his sky racer.
Tom's wizard camera, his great searchlight, his giant cannon, his photo telephone, his aerial warship and the big tunnel he helped to dig, brought him credit, fame, and not a little money. He had not long been back from an expedition to Honduras, dubbed "the land of wonders," when he was again busy on some of his many ideas. And it was to get some relief from his thoughts that he had taken the flight with Mr. Damon on the day the present story opens.
