I found the underground works of the dogs similar in other railroad cuts. None of the holes reached water, in fact, they were extra dry in the bottom. Prairie dogs in common with many species of plants and animals of the arid districts require and use but little water. Dogs do without water for weeks except such moisture as is obtained from plants eaten. A part of each year the plants are about as dry as dog biscuit. There were from a few dozen to a thousand dogs upon or in an acre; from a few holes to more than one hundred in an area the size of a baseball diamond. Although the plains had numerous large and populous places there were leagues without a single dog. Apparently the dogs keep on the higher and the well-drained land. One day I watched some fat, happy puppies amusing themselves. They played, but without much pep, while mothers remained near to guard and to admire. Prairie dogs often play. But never, I think, alone like the grizzly. In groups and in hundreds they played the universal game of tag. They were fat and low-geared and their running gallop made an amusing effort to get somewhere. There were several boxing exhibitions, or farces. Their fat bodies and extremely short legs and slow, awkward movement made their efforts more ludicrous even than those of fat men boxers. There was a kind of snake dance with entangled countermarching in which most dogs tried to be dignified while many acted as though in new company and did not know what was expected of them. One of their plays consisted in a single dog mimicking a stranger or an enemy. A bunch of dogs acted as spectators while an old dog highly entertained them by impersonating a coyote, at least his exhibition reminded me very much of coyote. The old dog imitated the coyote’s progress through dog town, with the usual turning, looking, smelling, and stopping. He looked into holes, rolled over, bayed at the heavens, and even tried the three-legged gallop. During most of his stunts the spectators were silent but toward the last he was applauded with violent cursings and denunciation--at least so it sounded. A number of other folks were imitated, but just who they were my natural history and the actor’s presentation gave no clue. Apparently the skunk was imitated. The actor’s interpretation was good. The congested audience watched him closely, with now and then a yip, but mostly in silence. But sometimes there are less peaceful scenes in dog town. A dog town without a coyote would be like Hades without Mephistopheles. The prairie dog likes to keep close to his hole, or to the hole of a neighbour into which he can duck and escape the surprise raids of the coyote.
