The old mill was infested with them as an old brewery with rats. But in many respects besides beauty they were an improvement on rats: they did not smell, they were not vicious, and they did not move by night.
During the daytime they were everywhere and into everything. Our slender stock of provisions was badly reduced when, by mischance, the tin box was left open a few hours, but we loved to see so much beautiful life about and so forgave them. One of our regular pleasures was to sit back after a meal and watch these pert-eyed, four-legged birds scramble onto the table, eat the scraps and lick all the plates and platters clean.
Like all the Chipmunks and Ground-squirrels, this animal has well-developed cheek-pouches which it uses for carrying home seeds and roots which serve for food in the winter. Or perhaps we should say in the early spring, for the Chipmunk, like the Ground-squirrel, goes into the ground for a long repose as soon as winter comes down hard and white.
Yet it does not go so early or stay so late as its big cousin. October still sees it active, even running about in the snow. As late as October 31st at Breckenridge, Col., I saw one sitting up on a log and eating some grass or seeds during a driving snowstorm. High up in the Shoshonees, after winter had settled down, on October 8, 1898, I saw one of these bright creatures bounding through the snow. On a stone he paused to watch me and I made a hasty sketch of his attitude.
Then, again, it is out in the spring, early in April, so that it is above ground for at least seven months of the year. Its nest is in a chamber at the end of a long tunnel that it digs under ground, usually among roots that make hard digging for the creatures that would rout them out. Very little is known as yet, however, about the growth or development of the young, so here is an opportunity for the young naturalist who would contribute something to our knowledge of this interesting creature.
