"Do you see that carriage yonder?—the one that is just about to turn the corner? Follow it wherever it goes and I'll pay you well."

"Enough said!" the man responded.

As we have seen, the boy entered the cab, and was driven away.

"That brakeman will think that I am a thief, too, I'm afraid," Al mused. "Well, I can't help it; it will be all right to-morrow. But he is a good fellow, and I don't like the idea of being misunderstood in that way by him even for a few hours. There's no help for it, though; I couldn't afford to let Farley get away from me!"

The two vehicles kept at an even distance from each other until Tenth Street was reached. At the corner of that thoroughfare and Fifth Avenue the carriage in advance came to a sudden halt.

Al's driver stopped almost at the same moment.

"What shall I do now, sir?" he called out to his passenger.

"Go right ahead," the boy directed. "When you get to the spot, stop, if the other coach has not started again in the meantime; if it has, go on as long as it does."

In less than a minute later Al's carriage once more come to a standstill.

At the same moment a man leaped from the other carriage, advanced to the cab and threw open the door.
