THE GROUND-SQUIRREL THAT PLAYS PICKET-PIN

Conspicuous in its teeming numbers in the Yellowstone Park is the Picket-Pin Ground-squirrel. On every level, dry prairie along the great river I found it in swarms.

It looks much like a common Squirrel, but its coat has become more mud-coloured, and its tail is reduced by long ages of neglect to a mere vestige of the ancestral banner. It has developed great powers of burrowing, but it never climbs anything higher than the little mound that it makes about the door of its home.

The Picket-pin is an interesting and picturesque creature in some ways, but it has one habit that I cannot quite condone. In this land of sun and bright blue air, this world of outdoor charm, it comes forth tardily in late spring, as late sometimes as the first of May, and promptly retires in mid-August, when blazing summer is on the face of the earth, and the land is a land of plenty. Down it goes after three and one half short months, to sleep for eight and a half long ones; and since during these three and a half months it is above ground only in broad daylight, this means that for only two months of the year it is active, and the other ten, four fifths of its life, it passes in a deathlike sleep.

Of course, the Picket-pin might reply that it has probably as many hours of active life as any of its kind, only it breaks them up into sections, with long blanks of rest between. Whether this defense is a good one or not, we have no facts at present to determine.

It has a fashion of sitting up straight on the doorway mound when it wishes to take an observation, and the more it is alarmed by the approach of an enemy the straighter it sits up, pressing its paws tight to its ribs, so that at a short distance it looks like a picket-pin of wood; hence the name.

Oftentimes some tenderfoot going in the evening to stake out his horse and making toward the selected patch of grassy prairie, exclaims, "Good Luck! here's a picket-pin already driven in." But on leading up his horse within ten or twelve feet of the pin, it gives a little "chirr" and dives down out of sight. Then the said tenderfoot realizes why the creature got the name.

The summer of 1897 I spent in the Park about Yancey's and there had daily chances of seeing the Picket-pin and learning its ways, for the species was there in thousands on the little prairie about my cabin. I think I am safe in saying that there were ten families to the acre of land on all the level prairie in this valley.
