"Why, Uncle Wiggily!" cried Jillie. "How can you give Squeaky a slide down hill when there is no snow? You need a slippery snow hill for sleigh-riding."

"I am not so sure of that," spoke Uncle Wiggily, with a smile. "Let us see."

Off through the woods he hopped, with Jillie and Squeaky following. Pretty soon Uncle Wiggily came to a big tree that had fallen down, one end being raised up higher than the other, like a hill, slanting.

With his strong paws and his sharp teeth, the rabbit gentleman began peeling the bark off the tree, showing the white wood underneath.

"What are you doing, Uncle Wiggily?" asked Jillie.

"This is a slippery elm tree, and I am making a hill so Squeaky-Eeky can slide down," answered the bunny uncle. "Underneath the bark the trunk of the elm tree is very slippery. Dr. Possum told me so. See how my paw slips!" And indeed it did, sliding down the sloping tree almost as fast as you can eat a lollypop.

Uncle Wiggily took off a lot of bark from the elm tree, making a long, sliding, slippery place.

"Now, try that with your sled, Squeaky-Eeky," said the bunny uncle. And the little cousin mouse did. She put her sled on the slanting tree, sat down and Jillie gave her a little push. Down the slippery elm tree went Squeaky as fast as anything, coming to a stop in a pile of soft leaves.

"Oh, what a lovely slide!" cried Squeaky. "You try it, Jillie." And the little mouse girl did.

"Who would think," she said, "that you could slide down a slippery elm tree? But you can."
