Their tails were very short, and not bushy as those of squirrels; and altogether their bodies had not the graceful symmetry of these animals.

In a short time every mound had two or three on its top--for several individuals dwell together in the same house.

Some sat upon all fours, while others erected themselves on their hind-feet, and stood up like little bears or monkeys--all the while flourishing their tails and uttering their tiny barking, that sounded like the squeak of a toy-dog.

It is from this that they derive the name of "prairie-dogs," for in nothing else do they resemble the canine species.

Like all marmots--and there are many different kinds-- they are innocent little creatures, and live upon grass, seeds, and roots.
