“Of course it has,” said the squirrel. “The idea of living in a house without a roof to it! I build it high up in the fork of a tree,” he went on; “and I lie curled up inside it, as snug and as warm as can be.”

“But isn’t it too warm in the summer?” asked Tommy Smith.

“Oh, I don’t go into it then,” said the squirrel. “The house I have been telling you about is for the winter, but in the summer I have my summer-house to go into.”

“Oh, then you have two houses!” said Tommy Smith. “That is cleverer than a bird, for they have only one nest.”

I have two,” said the squirrel, “and they are not at all the same.”

“Oh, do tell me what the summer-house is like,” said Tommy Smith.

“It is more lightly built than the winter-house,” said the squirrel, “and not nearly so large. That is how summer-houses are always built, you know. Perhaps you have one in your garden.”

“Oh yes, we have,” said Tommy Smith.

“And isn’t it much smaller than the other one?” said the squirrel.

“Oh yes, it is,” said Tommy Smith.
