"You're richer than I supposed," said the conductor. "Here's your change."

The boy put back the twenty-two cents remaining in the pocket of his ragged pants, and began to look about him for the passenger whom he was required to track. The latter was seated on the left hand side, four seats from the door.

"I wonder why I'm to foller him about," said the boy to himself. "Maybe he's run off without paying his bill. Anyway, it's nothing to me as long as I earn a quarter. It'll pay me into the Old Bowery to-night."

And the boy began to indulge in pleasing anticipations of the enjoyment he would receive from witnessing the great spectacle of the "Avenger of Blood," which was having a successful run at the favorite theatre with boys of his class.

Before proceeding, I may mention that the boy referred to was known as Hake, a name whose derivation I have been unable to learn. He had been a street vagrant for half his life, and was precocious in his knowledge of metropolitan life in its lowest phases.

If the gentleman whom he was employed to watch noticed the ragged boy, he hadn't the remotest suspicion that there was the least connection between them, or that his being there had anything to do with his own presence in the car. He took out a paper from his pocket and began to read.

"I wonder how far I've got to go," thought Hake. "If it's far I'll have to ride back, and that'll take three cents more."

He reflected, however, that nineteen cents would remain, and he would besides have the quarter which had been promised him.

"I can go to the theatre, and get a bully dinner, besides," he reflected, complacently.

The car rapidly proceeded uptown, passing Union Square and the Everett House at the corner of Seventeenth Street. Two blocks farther, and the passenger first introduced rose from his seat.
