"Let who know?" asked Mappo.

"Sharp-Tooth, the tiger. Don't tell him I'm here," Tum Tum said.

"Why not?" the little monkey wanted to know.

"Well, because he and I aren't friends," said Tum Tum. "You know in the jungle, hunters sometimes ride on the backs of myself, and my elephant friends, to hunt tigers. That's why the tigers don't like us. So don't mention to Sharp-Tooth that I'm on board this ship."

"I won't, of course," spoke Mappo in his funny, monkey talk. "But it wouldn't matter, anyhow, as he's in a cage."

"He might break loose, and scratch me," said Tum Tum. "So don't mention it to him."

Mappo promised not to. He sat up there on the elephant's back a long time, and they talked of many things that had happened in the jungle woods.

"Well, you two seem to like each other so well that I guess I'll leave you together," said the sailor, when he came back and found Mappo asleep on Tum Tum's back. "I'll bring the monkey's cage down here," the sailor went on, "and let him stay. They might just as well get acquainted, for they'll be together in the circus, anyhow."

"That will be nice," thought Mappo, as he heard what the sailor said.

Many things happened to Mappo aboard the ship in which he journeyed from the jungle to this country. I have not room to tell you about all of them in this book.
