on his guard.

"Could you oblige me with small bills for a ten? I am owing a dollar to
the porter."

Andy took out a large-sized wallet from an inner pocket and opened it.
It contained about fifty dollars in bills of different denominations.

"I am afraid I cannot accommodate you," he said, "unless two five-dollar
bills will answer your purpose."

"I am afraid it won't help me."

"I am sorry," said Andy, politely.

He did not observe the covetous glance of the stranger as he noted the
large wallet and its contents. It occurred to him afterward that his
companion had not produced the bill he wished changed.

"Oh, well," said the stranger, carelessly, "it doesn't matter. I can get
the bill changed at the depot. Are you traveling on business?" he
inquired.

"Yes, sir."

"So am I. I represent the firm of Arnold & Constable, in New York.
Doubtless you have heard of them."

"Oh, yes. They are well known."
