ptain with increased respect.

"I didn't know that," he answered, duly impressed.

"Yes, I've had experience as a teacher. Now, if you don't mind, I'll ask
you a few questions, and find out how much you know. We've got plenty of
time, for it's a long way to Pancake Lock."

"Don't ask me too hard questions," said the boy. "I'll answer the best I
know."

Upon this Captain Letcher, taking a little time to think, began to
question his young cousin in the different branches he had enumerated.
The questions were not very hard, for the good captain, though he had
taught school in Indiana, was not a profound scholar.

James answered every question promptly and accurately, to the increasing
surprise of his employer.

The latter paused.

"Haven't you any more questions?" asked James.

"No, I don't think of any."

"Then may I ask you some?"

"Yes, if you want to," answered the captain, rather surprised.

"Very well," said James. "A man went to a shoemaker and bought a pair of
boots, for which he was to pay five dollars. He offered a fifty-dollar
bill, which the shoemaker sent out and had changed. He paid his customer
forty-five dollars in change, and the latter walked off with the boots.
An hour later he ascertained that the bill was a counterfeit, and he was
obliged to pay back fifty dollars in good money to the man who had
changed the bill for him. Now, how much did he lose?"

"That's easy enough. He lost fifty dollars and the boots."

"I don't think that's quite right," said James, smiling.

money, and didn't the man walk off with the boots?"

"That's true; but he neither lost nor made by changing the bill. He
received fifty dollars in good money and paid back the same, didn't he?"

"Yes."

"Whatever he lost his customer made, didn't he?"

"Yes."

"Well, the man walked off with forty-five dollars and a pair of boots.
The other five dollars the shoemaker kept himself."

"That's so, Jim. I see it now, but it's rather puzzling at first. Did
you make that out yourself?"

"Yes."

"Then you've got a good head--better than I expected. Have you got any
more questions?"

"Just a few."

So the boy continued to ask questions, and the captain was more than
once obliged to confess that he could not answer. He began to form a
new opinion of his young cousin, who, though he filled the humble
