"They won't—won't dare to kill me," said the fellow. "I'm a—a—good citizen."

"He ought to be locked up," said a man standing near.

"It was a brave deed," said one of the ladies.

"Who's goin' to lock me up?" demanded the tramp, for he was nothing less. And he began to show fight, at which the majority of the crowd turned away, and hurried to board the train. Nat hesitated for a second, and then concluded to let the train go on and take the next one.

"Say, you pulled me from the track, didn't you?" said the man, after another look at Nat.

"I did."

"Noble boy. I ought to reward you."

"I don't want any reward."

"Humph! Don't worry, my dear friend—Tom Nolan ain't got no money to reward you with." And the semi-drunken man indulged in a senseless chuckle.

"See here, haven't I met you before?" demanded Nat, looking at the man more closely than ever.
