Half way up the side of a tall tree there was a round hole in the trunk. The hole was lined with soft, dried leaves, and bits of white, fluffy cotton, from the milkweed plant. And, if you looked very carefully at the hole, you might see, peering from it, a little head, like that of a very small kitten, and a pair of very bright eyes. 

But it was not a kitten that looked from the little hole in the trunk of the tree. Kitties can climb trees, but they do not like to live in them. They would rather have a warm place behind the stove, with a nice saucer of milk. 

Now if I tell you that the little creatures who lived in this hole-nest had big, fluffy tails, and that they could sit up on their hind legs, and eat nuts, I am sure you can guess what they were. 

Squirrels! That's it! In the nest, half way up the big tree in the woods, lived a family of gray squirrels, and I am going to tell you about them, or, rather, more particularly, about one of the little girl squirrels whose name was Slicko.
