"If you've had your three wishes, it's no good to you now, then, Morris," said the old man at last. "What do you keep it for?"

The soldier shook his head. "Fancy, I suppose," he said, slowly. "I did have some idea of selling it, but I don't think I will. It has caused enough mischief already. Besides, people won't buy. They think it's a fairy tale; some of them, and those who do think anything of it want to try it first and pay me afterward"

"If you could have another three wishes," said the old man, eyeing him keenly, "would you have them?"

"I don't know," said the other. "I don't know."

He took the paw, and dangling it between his forefinger and thumb, suddenly threw it upon the fire. White, with a slight cry, stooped down and snatched it off.
