“And you gave it up to him?”

“Yes, but not till he paid me the twenty dollars I gave for it.”

The other was more and more mystified.

“Jim Beckwith gave you twenty dollars?” he said.

“Yes. That leaves me all right. If you want to buy it back at any time you must apply to him.”

The man in the white hat stared at Walter as if he was a museum freak.

“Boy,” he said, in a tone of enforced admiration, “you're smart!”

“I am glad you think so, sir,” returned Walter. “You pay me a compliment.”

“How old are you?”

“Seventeen.”
