Then came an unexpected turn of affairs, and from that moment Dave's future seemed assured. As related in my first volume, "Dave Porter at Oak Hall," the boy called upon Mr. Oliver Wadsworth, a rich manufacturer of that neighborhood. The gentleman had a daughter Jessie, a bright-eyed miss some years younger than Dave. She was waiting to take an automobile ride when the gasoline tank of the machine caught fire. It was plucky Dave who rushed in and, at the peril of his own life, saved the girl from being fatally burned.
The Wadsworths were more than grateful, and when Mr. Wadsworth discovered that Caspar Potts was one of his former college teachers, he insisted that both the old man and Dave come to live at his mansion. He took a great interest in Dave, more especially as he had had a son about Dave's age who had died.
"The lad must go to some boarding school," said Oliver Wadsworth, and at his own expense he sent Dave to Oak Hall. With Dave went Ben Basswood, a friend of several years' standing.
Dave made friends with great rapidity. First came Roger Morr, the son of a United States senator, then Phil Lawrence, whose father was a wealthy ship-owner, Sam Day, who was usually called "Lazy," because he was so big and fat, "Buster" Beggs, "Shadow" Hamilton, and a number of others, whom we shall meet as our story proceeds.
For a while all went well with Dave, but then came trouble with Nat Poole, who had come to the Hall, and with Gus Plum, the school bully, and Chip Macklin, his toady. The cry of "poorhouse nobody" was again raised, and Dave felt almost like leaving Oak Hall in disgust.
"I must find out who I really am," he told himself, and fortune presently favored him. By a curious turn of circumstances he fell in with an old sailor named Billy Dill. This tar declared he knew Dave or somebody who looked exactly like him. This unknown individual was on an island in the South Seas.
"My father's ships sail to the South Seas," Phil Lawrence told Dave, and the upshot of the matter was that Dave took passage on one of the vessels, in company with the ship-owner's son, Roger Morr, and Billy Dill.
As already related in the second volume of this series, "Dave Porter in the South Seas," the voyage of the _Stormy Petrel_ proved to be anything but an uneventful one. Fearful storms arose, and Dave and some others were cast away on an uninhabited island. But in the end all went well, and, much to the lad's joy, he found an uncle named Dunston Porter.
