"I guess you have been here long enough, Mappo," said the sailor. "You might get hurt down here, with all these big elephants."

Mappo was glad enough to go, not that he felt afraid of the elephants, but he knew that one of them might, by accident, fall on him, and an elephant is so large and heavy that, when he falls on a monkey, there is not much left of the little chap.

"Good-by, Tum Tum!" called Mappo to his big friend. "I'll come and see you, when the storm is over."

"All right," answered Tum Tum. "And I hope the storm will soon be over, for I do not like it."

The ship was swinging to and fro, like a rocking chair on the front porch when the wind blows. But finally the elephants became used to it, and some of them could even go to sleep. But Tum Tum stayed awake.

"There might be some danger," he thought to himself, "and if there was, I could warn the others. I am the leader, and must always be on the watch for danger, just as Mr. Boom would be, if he were here."

But I am glad to say no more danger came to the ship. It rode safely through the storm, and in a few days, it was gliding swiftly over the blue sea.

"What will happen to us, when the ship stops sailing?" asked Tum Tum of the old elephant, who seemed to know so much.

"After it gets to the other side of the ocean," said the old elephant, "we shall be taken out—we and all the animals. Then we shall go to the circus."

"Is the circus nice?" asked Tum Tum.
