My friend John lives in Colorado, not far from Denver; and he writes me, that he and his sister, not long ago, walked out to see some prairie-dogs.

The prairie-dog is about the size of a full-grown squirrel, and of a like color. It makes a hole for itself in the ground. This hole is in the shape of a tunnel, and as large round as a man's hat.

Now, this little dog is so gentle, that he lets the owl and the rattlesnake come and live with him, if they like. All three are often found dwelling together. For my part, I should not much like such neighbors.

The prairie-dogs live on the roots of grass. Scattered all around the entrance to their homes, you may see remnants of the dry roots which they have got for food. They are quick in their movements, and quite playful.

Johnny writes me, that, when some of these little dogs saw him and his sister approaching, they sat down on their hind-legs, and began barking. Then they dropped into their holes backwards. As Johnny did not care to wake up any of the other lodgers, he and his sister went home, well content with their first sight of a prairie-dog.
