Seizing his fishing tackle the old man fled to the nearest stream. And there gazing into the deep, still waters, where he had cast his hook, he came to understand. It was that same dominant note in the boy's life, that inborn passion to serve, that fixed principle in his character that his life must be of the greatest possible worth to the world, that had led him to make his choice. With that instinct born in him, coming from the influence of the old Shepherd upon his father and mother, the boy could no more escape it than he could change the color of his brown eyes. "But," said the Doctor to his cork, that floated on the surface in a patch of shadow, "what does he know about it, what does he really know? He's been reading history--that's what's the matter with him. He sees things as they were, not as they are. He should have come to me, I could have--" Just then the cork went under. The Doctor had a bite. "I could have told him," repeated the fisherman softly, "I--" The cork bobbed up again--it was only a nibble. "He'll find out the truth of course. He's that kind. But when he finds it!" The cork bobbed again--"He'll need me, he'll need me bad!" The cork went under for good this time. Zip--and the Doctor had a big one! With fresh bait and his hook once more well down toward the bottom the Doctor saw the whole thing clearly, and so planned a way by which, as he put it, he might, when Dan needed him, "_stand by_." CHAPTER III. A GREAT DAY IN CORINTH "'Talk of the responsibilities of age; humph! They are nothing compared to the responsibilities of youth. There's Dan, now--'" Corinth was in the midst of a street fair. The neighboring city held a street fair that year, therefore Corinth. All that the city does Corinth imitates, thereby with a beautiful rural simplicity thinking herself metropolitan, just as those who take their styles from the metropolis feel themselves well dressed. The very Corinthian clerks and grocery boys, lounging behind their counters and in the doorways, the lawyer's understudy with his feet on the window sill, the mechanic's apprentice, the high school youths and the local sporting fraternity--all imitated their city kind and talked smartly about the country "rubes" who came to town; never once dreaming that they themselves, when they "go to town," are as much a mark for the like wit of their city brothers. So Corinth was in the midst of a street fair.
