I took my own place in the work, and having been so much about the store that day, it was necessary that I disguise myself, as I did; and I took my station on Broadway, near the store, and waited for the young men to sally forth, directing my men to the boarding-places of some of the clerks, with as accurate descriptions of them as I could give. I had not long to wait before some of the clerks passed me, and I selected two, whom I followed. Darkness was just coming on. They stopped on a corner to lay out their programme for the evening, and concluded to not go home to tea, but to go to a restaurant, where I followed them, and remained there till they left; and when they came out they went up Broadway, and stopping before a billiard saloon, seemed to be debating the question whether they would go up or not; but finally they went up the stairs, and I remained behind a few minutes, and then followed them. Somehow, as I entered the room, and my eye fell upon the face of one of them, something seemed to tell me that he was the guilty fellow. The young men had already commenced a game, and were busy with the bewitching balls. I lounged about, and finally got a partner for a single game. The young men did not bet--only played for sport, and at a seasonable hour left, not however, till I, having observed that they would soon depart, had gotten down on to the pavement before them. When they came down, they set off together, walked some distance together, turned down a side street, and on the corner of it and another street bade each other good night. One of them went on to his boarding-house, and so I suppose did the other. The next night I gave my particular attentions to those same young men. They went over to the Bowery Theatre, and like sensible fellows, too, had seats in the pit, in which part of the house I also secured a place. They seemed to enjoy the play greatly, and one of them threw a quarter of a dollar on the stage in lieu of a bouquet, in testimony of his appreciation of the splendid representation of a mock Richard the Third by the leading actor, and I fancied that perhaps I had found out the young man's leading passion--his besetting sin.
