The Scarecrow, in shifting his seat, saw upon the cushions the pepper-box which Tip had cast aside, and began to examine it.

"Throw it overboard," said the boy; "it's quite empty now, and there's no use keeping it."

"Is it really empty?" asked the Scarecrow, looking curiously into the box.

"Of course it is," answered Tip. "I shook out every grain of the powder."

"Then the box has two bottoms," announced the Scarecrow; "for the bottom on the inside is fully an inch away from the bottom on the outside."

"Let me see," said the Tin Woodman, taking the box from his friend. "Yes," he declared, after looking it over, "the thing certainly has a false bottom. Now, I wonder what that is for?"

"Can't you get it apart, and find out?" enquired Tip, now quite interested in the mystery.

"Why, yes; the lower bottom unscrews," said the Tin Woodman. "My fingers are rather stiff; please see if you can open it."

He handed the pepper-box to Tip, who had no difficulty in unscrewing the bottom. And in the cavity below were three silver pills, with a carefully folded paper lying underneath them.
