“And where did you expect to find me? I haven’t been out of my room before to-night.”

“Didn’t you write me a note stating that you had found a steamer that was going to sail for Galveston inside of half an hour?”

“I!” exclaimed George, in great amazement. “No, sir.”

“There!” said Bob. “I told the watchman he had made a mistake. Here’s the note.”

George read the note, and so did the clerk; and then the watchman, who happened to pass by at that moment, was called upon for an explanation. “Where did you get this note?” asked the clerk.

“From dat gemman out dar in de carriage, sar,” was the prompt reply.

“Let’s go and see if it is any one we know,” said George.

The two boys hurried to the sidewalk, and, when they reached it, found there was no carriage there. The watchman, who had followed close at their heels, seemed to be very much astonished.

“The gentleman, whoever he was, found that he had made a mistake, and so he drove off,” said George, as he tore the note into the smallest possible fragments, and put them into his pocket. “It is of no consequence. Let’s go back to bed, Bob.”

They stopped for a few minutes at the desk, to compare notes with the clerk and the watchman; and, when everybody was satisfied that it was the man in the carriage, and not the darkey, who had made the mistake, Bob saw his money put back into the safe, and he and George went up-stairs. The latter went into Bob’s room, and, when he had closed and locked the door, proceeded to explain how he had happened to follow Bob to the office.
