As I emerged from the woods into a cornfield and turned to look over at the gloomy pines, a snowflake fell softly upon my arm. The storm had begun. Now the half-starved crows came flocking in by hundreds, hurrying to roost before the darkness should overtake them. A biting wind was rising; already I could hear it soughing through the pines. There was something fascinating in the oncoming monster, and backing up behind a corn-shock, I stopped a little to watch the sweep of its white winds between me and the dark, sounding pines. [Illustration: "I shivered as the icy flakes fell thicker and faster."] I shivered as the icy flakes fell thicker and faster. How the wild, unhoused things must suffer to-night! I thought, as the weary procession of crows beat on toward the trees. Presently there was a small stir within the corn-shock. I laid my ear to the stalks and listened. Mice! I could hear them moving around in there. It was with relief that I felt that here, at least, was a little people whom the cold and night could not hurt. These mice were as warmly sheltered inside this great shock as I should be in my furnace-warmed home. Their tiny nests of corn-silk, hidden away, perhaps, within the stiff, empty husks at the shock's very center, could never be wet by a drop of the most driving rain nor reached by the most searching frosts. And not a mouse of them feared starvation. A plenty of nubbins had been left from the husking, and they would have corn for the shelling far into the spring--if the fodder and their homes should be left to them so long. I floundered on toward home. In the gathering night, amid the swirl of the snow, the shocks seemed like spectral tents pitched up and down some ghostly camp. But the specters and ghosts were all with me, all out in the whirling storm. The mice knew nothing of wandering, shivering spirits; they nibbled their corn and squeaked in snug contentment; for only dreams of the winter come to them in there. These shock-dwellers were the common house-mice, _Mus musculus_. But they are not the only mice that have warm beds in winter. In fact, bed-making is a specialty among the mice. _Zapus_, the jumping-mouse, the exquisite little fellow with the long tail and kangaroo legs, has made his nest of leaves and grass down in the ground, where he lies in a tiny ball just out of the frost's reach, fast asleep. He will be plowed out of bed next spring, if his nest is in a field destined for corn or melons; for _Zapus_ is sure to oversleep. He is a very sound sleeper. The bluebirds, robins, and song-sparrows will have been back for weeks, the fields will be turning green, and as for the flowers, there will be a long procession of them started, before this pretty sleepy-head rubs his eyes, uncurls himself, and digs his way out to see the new spring morning. Does this winter-long sleep seem to him only as a nap overnight? [Illustration: The meadow-mouse.]
