"This is counterfeit!"

It was in the First National Bank of Carson, between nine and ten o'clock of the day following Frank's arrival in the city.

Frank had found it difficult to get either of the new fifty-dollar bills changed, and so he stepped into the bank and asked if he could be favored there.

The bill had been scrutinized closely, the cashier had examined it beneath a magnifying glass, after which he questioned the boy concerning his manner of obtaining the paper, and Frank had told the truth fully and without hesitation. Then the boy had been called into a private room, and the cashier had declared the bill counterfeit.

Frank had been prepared for such an assertion by what went before it, and he immediately opened his pocketbook and produced the other bill which he had received of Isa Isban.

"Please look at this, and see if it is also counterfeit," he asked, with remarkable coolness.

In a moment the cashier said:

"It is a mate for the first one. Both are 'queer.' My boy, this is bad stuff to be carrying around. It is liable to bring you into no end of trouble."

As he said this he was regarding Frank's face with a searching stare, as if seeking to discover if the lad were honest or crooked.

Frank knew he was under suspicion, and he bore himself as quietly as possible.
