"I make my home down in the ground," replied Striped Chipmunk. "I dig a tunnel just big enough to run along comfortably. Down deep enough to be out of reach of Jack Frost I make a nice little bedroom with a bed of grass and leaves, and I make another little room for a storeroom in which to keep my supply of seeds and nuts. Sometimes I have more than one storeroom. Also I have some little side tunnels."

"But why is it I never have been able to find the entrance to your tunnel?" asked Peter, as full of curiosity as ever.

"Because I have it hidden underneath the stone wall on the edge of the Old Orchard," replied Striped Chipmunk.

"But even then, I should think that all the sand you must have taken out would give your secret away," cried Peter.

Striped Chipmunk chuckled happily. It was a throaty little chuckle, pleasant to hear. "I looked out for that," said he. "There isn't a grain of that sand around my doorway. I took it all out through another hole some distance away, a sort of back door, and then closed it up solidly. If you please, Mother Nature, if I am not a Ground Squirrel, who is?"
