The story at first blush seems incredible, but I have no doubt our red squirrel would have made the leap safely; then why not the great black squirrel, since its parachute would be proportionately large? The tails of the squirrels are broad and long and flat, not short and small like those of gophers, chipmunks, woodchucks, and other ground rodents, and when they leap or fall through the air the tail is arched and rapidly vibrates. A squirrel's tail, therefore, is something more than ornament, something more than a flag; it not only aids him in flying, but it serves as a cloak, which he wraps about him when he sleeps. Thus, some animals put their tails to various uses, while others seem to have no use for them whatever. What use for a tail has a wood-chuck, or a weasel, or a mouse? Has not the mouse yet learned that it could get in its hole sooner if it had no tail? The mole and the meadow mouse have very short tails. Rats, no doubt, put their tails to various uses. The rabbit has no use for a tail,--it would be in its way; while its manner of sleeping is such that it does not need a tail to tuck itself up with, as do the coon and the fox. The dog talks with his tail; the tail of the possum is prehensile; the porcupine uses his tail in climbing and for defense; the beaver as a tool or trowel; while the tail of the skunk serves as a screen behind which it masks its terrible battery. THE WOODCHUCK Writers upon rural England and her familiar natural history make no mention of the marmot or woodchuck. In Europe this animal seems to be confined to the high mountainous districts, as on our Pacific slope, burrowing near the snow-line. It is more social or gregarious than the American species, living in large families like our prairie dog. In the Middle and Eastern States our woodchuck takes the place, in some respects, of the English rabbit, burrowing in every hillside and under every stone wall and jutting ledge and large boulder, from whence it makes raids upon the grass and clover and sometimes upon the garden vegetables. It is quite solitary in its habits, seldom more than one inhabiting the same den, unless it be a mother and her young. It is not now so much a WOODchuck as a FIELDchuck. Occasionally, however, one seems to prefer the woods, and is not seduced by the sunny slopes and the succulent grass, but feeds, as did his fathers before him, upon roots and twigs, the bark of young trees, and upon various wood plants.
