"Come in and sit down for a minute and rest yourself," invited Grandpa Whackum.

"I will," said Uncle Wiggily. "And I'll leave my butter outside where it will be cool," for Grandpa Whackum lived down in an underground house, where it was so warm, in summer, that butter would melt.

Grandpa Whackum was a beaver, and he was called Whackum because he used to whack his broad, flat tail on the ground, like beating a drum, to warn the other beavers of danger. Beavers, you know, are something like big muskrats, and they like water. Their tails are flat, like a pancake or egg turner.

"Well, how are things with you, and how is Nurse Jane?" asked Grandpa Whackum.

"Oh, everything is fine," said Uncle Wiggily. "Nurse Jane is well. I've just been to the store to get her some butter."

"That's just like you; always doing something for some one," said Grandpa Whackum, pleased like.

Then the two friends talked for some little while longer, until it was almost 6 o'clock, and time for Uncle Wiggily to go.

"I'll take my butter and travel along," he said. But when he went outside, where he had left the pound of butter on a flat stump, it wasn't there.

"Why, this is queer," said the bunny uncle. "I wonder if Nurse Jane could have come along and taken it to the hollow stump bungalow herself?"

"More likely a bad fox took the butter," spoke the old gentleman beaver. "But we can soon tell. I'll look in the dirt around the stump and see whose footprints are there. A fox makes different tracks from a muskrat."
