"Take the wheel!" shouted Dick to Paul. And then, as the motor-boat shot ahead, the rich youth leaned over the gunwale, and, holding on to a forward deck cleat with one hand, he reached over, and with the other, caught the coat collar of the swimmer, who had thrown up his arms, and was about to sink again. "I'll give you a hand!" cried Innis, and between them the cadets lifted into the boat the now inert form of Jack Butt. "Stop the motor!" "First aid!" "We've got to try artificial respiration!" In turn Innis, Paul and Dick shot out these words. And, seeing that the other two rescued ones were in no need of attention, the cadets proceeded to put to practical use the lessons in first aid to the drowning they had learned at Kentfield. And, while this is going on I am going to take just a few moments, in which to tell my new readers something about the previous books in this series. The only son of Mortimer Hamilton, of Hamilton Corners, in New York state, Dick was a millionaire in his own right. His mother had left him a large estate, and in the first volume of this series, entitled, "Dick Hamilton's Fortune; Or, The Stirring Doings of a Millionaire's Son," I related what Dick had to do in order to become fully possessed of a large sum of money. He had to prove that he was really capable of handling it, and he nearly came to grief in doing this, as many a better youth might have done. Dick's uncle, Ezra Larabee, of Dankville, was a rich man, but a miser. He was not in sympathy with Dick, nor with the plans his sister, Dick's mother, had made for her son. Consequently, Uncle Ezra did all he could to make it unpleasant for Dick while the latter was paying him a visit of importance. But Dick triumphed over his uncle, and also over certain sharpers who tried to get the best of him. My second volume, entitled, "Dick Hamilton's Cadet Days, Or, The Handicap of a Millionaire's Son," deals with our hero's activities at the Kentfield Military Academy. This was a well-known school, at the head of which was Colonel Masterly. Major Henry Rockford was the commandant, and the institution turned out many first-class young men, with a groundwork of military training. The school was under the supervision of officers from the regular army, the resident one being Major Webster. Dick had rather a hard time at Kentfield--at first--for he had to get over the handicap of being a millionaire. But how he did it you may read, and, I trust, enjoy. In "Dick Hamilton's Steam Yacht; Or, A Young Millionaire and the Kidnappers," Dick got into a "peck of trouble," to quote his chum, Innis Beeby. But the rich youth finally triumphed over the designs of Uncle Ezra, and was able to foil some plotters.
