"What's sliding down hill?" asked Umboo, and of course, you understand, all this talk was in animal language.

"Sliding down hill is fun," went on Keedah. "You know Old Tusker went up to the top of a place, called a hill, to look and see about the hunters in the jungle. Well, there is a hill on the other side of this river, and when we get across I'm going to the top of it and slide down.

"It's hard work going up hill," went on the larger elephant boy, "but it's easy coming down. You just sit on your hind legs, hold your trunk up in the air and down you come as fast as anything!"

"And be careful you don't bump into anything," said Mrs. Stumptail. "Sliding down hill is all right if you don't bump into anything. You must be careful, Umboo. Don't slide down any hills unless you ask me first."

"I won't," promised the baby elephant. "But tell me more about it,
Keedah. Did you ever slide down hill?"

"Many a time. I was with the herd last year when we swam this same river. I could swim then, too, and when we came to the hill I climbed up. Then I came down lots faster than I walked up, and I went splash into the river. That didn't hurt at all," he said to Umboo's mother.

"No, it doesn't hurt to slide into the water," said the old elephant lady. "If you do any sliding, Umboo, see that you splash into the water, and not on the hard ground."

"I will, after I learn to swim," spoke Umboo.

A little later the herd of elephants were safely across the jungle river. Some rested in the shade of trees, pulling off the low branches and the palm nuts. Others rolled in the mud, to make a sort of coating over their skins, to keep off the flies. Others went to the top of the hill to slide down, and Keedah went with them.

"Oh, mother! I wish I could slide!" said Umboo, when he saw what fun the other elephants were having. They really did slide down hill, just as otters do, only the otter, or beaver, likes to have water on his slide, and the elephants did not care whether their slide was wet or dry. Down they came, over sticks and stones, and their skin was so tough that they never got hurt. And yet a fly could bite through that same hide! But that is because a fly has a very fine, sharp bill, which can go through the tiny pores, or holes, in the elephant's skin.
