During the night the sleet changed to rain which froze as it fell, and in the morning the snow everywhere was but an inch or two deep and covered with an icy crust that broke underfoot with a great noise and effectually scared away any woodland thing that you approached, provided it had powers of locomotion. Fox or crow, partridge or rabbit, must have thought that Gulliver was once more walking in among the Lilliputians with his very biggest boots on. Never were such thunderous footsteps heard in my wood, at least not since the last icy crust. Frozen in the icy surface were the trails that had been made when the snow was soft, the squirrel’s long, plunging leaps with his hind feet dropping into the hole his front feet had made, giving something you might mistake for deer tracks, except that they went back up the tree. You saw where the crow had dropped to earth and trailed his aristocratically long hind toe, with its incurving claw. The crow’s foot is fine for grasping a limb, but it does not fit the ground well. On the other hand, the trail of the ruffed grouse which may lie beside it shows an ideal footprint for walking woodland paths, the hind toe stubby nailed, short but firm, and the whole print well planted and fitting the earth. These and many more I found modeled in ice, but the trails that interested me most were those beneath the crust, the long tunnels that wound here and there, intersected and doubled and made portions of the fields and forests for all the world like the blue veining of a white skin. These were the trails of the shaggy-coated, crop-eared, short-legged, shorttailed meadow mouse. This firm crust had opened to him the opportunity of safety in paths that had been before dangerous in the extreme. He knew where chestnuts had lain open to the sky for months, but he dared not go into the open path to get them. Fox, cat, skunk, weasel, hawk, owl, crow, all watched the paths and the edges of the thick grass for him. He must burrow or die. So he does burrow all the year through, just beneath the surface, in dirt if he must, under light leaves and brush and matted grasses by preference, for there he may go the more easily and quickly to his food. His eyesight and hearing are good, and he moves like a little brown flash when he has to go into the open.
