"Have you lost anything?" inquired a gentleman who sat just behind Walter. Looking back, he found that it was a gentleman of fifty who addressed him.

"Yes, sir," he said, "I have lost my pocket-book."

"Was there much money in it?"

"About forty dollars, sir."

"That is too much to lose. Was your ticket in it also?"

"No, sir; that I have in my vest-pocket."

"Where was your pocket-book when you last saw it?" inquired the gentleman.

"In this pocket, sir."

"Humph!" commented the other. "Who was that young man who was sitting with you a few minutes since?"

"I don't know, sir."
