Carl hurried on, and, picking up the bill, said to the small stranger as he touched his arm: “Here is some money you just dropped, sir.”

The little man turned round and smiled pleasantly.

“Thank you. Are you sure it is mine?”

“Yes, sir; it came out with your handkerchief.”

“Let me see. So it is mine. I was very careless to put it loose in my pocket.”

“You were rather careless, sir.”

“Of what denomination is it?’

“It is a two-dollar note.”

“If you had been a poor boy,” said the little man, eying Carl keenly, “you might have been tempted to keep it. I might not have known.”

Carl smiled.
