"We are not responsible for his position," retorted Roger. "He got himself into trouble."

"So he did, Roger. But, just the same, a fellow like Link Merwell is bound to blame somebody else,—and in this case he blames us. I am afraid he'll make trouble for us—if he gets the chance," concluded Dave, seriously.

And now, while the three chums are busy reading their letters again, let me introduce them more specifically than I have already done.

Dave Porter was a typical American lad, now well grown, and a graduate of Oak Hall, a high-class preparatory school for boys located in one of our eastern States.

While a mere child, Dave had been found wandering beside the railroad tracks near the little village of Crumville. He could not tell who he was, nor where he had come from, and not being claimed by any one, was taken to the local poor-house. There a broken-down college professor, Caspar Potts, had found him and given him a home.

In Crumville resided a rich jewelry manufacturer named Oliver Wadsworth, who had a daughter named Jessie. One day the Wadsworth automobile caught fire and Jessie was in danger of being burned to death, when Dave rushed to the rescue and saved her. For this Mr. Wadsworth was very grateful, and when he learned that Dave lived with Mr. Potts, who had been one of his instructors in college, he made the man and the youth come to live with him.

"Such a boy deserves to have a good education and I am going to give it to him," said the rich manufacturer, and so Dave was sent to boarding school, as related in the first volume of this series, entitled "Dave Porter at Oak Hall." There he made a host of friends, including Roger Morr, the son of a United States senator; Phil Lawrence, the son of a rich shipowner; Shadow Hamilton, who loved to tell stories; Buster Beggs, who was fat and jolly; Luke Watson, who was a musician of considerable skill, and many others.

The main thing that troubled Dave in those days was the question of his identity, and when one of his school rivals spoke of him as a "poor-house nobody" it disturbed him greatly. Receiving something of a clew, he went on a long voyage, as related in "Dave Porter in the South Seas," and located his uncle, Dunston Porter, and learned for the first time that his father, David Breslow Porter, was also living, and likewise a sister, Laura.

After his great trip on the ocean, our hero returned to Oak Hall, as related in "Dave Porter's Return to School." Then, as he had not yet met his father, he went in search of his parent, the quest, as told of in "Dave Porter in the Far North," taking him to Norway.

Glad to know that he could not be called a poor-house nobody in the future, Dave went back to Oak Hall once again, as related in "Dave Porter and His Classmates." He now made more friends than ever. But he likewise made some enemies, including Nick Jasniff, a very passionate fellow, who always wanted to fight, and Link Merwell, the son of a rich ranchowner of the West. Jasniff ran away from school, while under a cloud, and Merwell, after making serious trouble for Dave and his chums, was expelled.
