The opening into the tree had been barely large enough for him to squeeze through, and now he could pass in without crushing his fur. Around the edge of it were many marks of sharp teeth. Somebody had wanted to get in and had not found the doorway large enough. The Deer Mouse went inside and sat on his beechnuts. Then he thought and thought and thought. He knew very well that it was a Red Squirrel, for the Red Squirrels are not so thrifty as most of the nut-eaters. They make a great fuss about gathering food in the fall, and frisk and chatter and scold if anybody else comes where they are busy. For all that, the Chipmunks and the Deer Mice work much harder than they. It is not always the person who makes the greatest fuss, you know, who does the most.
