"It appears that Mr. Jones laid a twenty-dollar bill on his desk—a very careless proceeding, by the way—while he was waiting upon a customer in another part of the store. About five minutes afterward the Barton boy called upon him to fill a small can with kerosene, and actually had the hardihood to offer his own twenty-dollar bill in payment."

"Bert Barton offered Mr. Jones a twenty-dollar bill?" asked Percy, in great surprise.

"Yes; no wonder you are surprised at his boldness."

"Perhaps it wasn't the same bill," Percy was constrained to suggest.

"You must be a fool, Percy. Where else could he have got so large a bill as that? We all know how poor the Bartons are. Besides, the bill on the desk had disappeared."
