_Arvicola_, the meadow-mouse, that duck-legged, stump-tailed, pot-bellied mouse whose paths you see everywhere in the meadows and fields, stays wide awake all winter. He is not so tender as _Zapus_. The cold does not bother him; he likes it. Up he comes from his underground nest,--or home, rather, for it is more than a mere sleeping-place,--and runs out into the snow like a boy. He dives and plunges about in the soft white drifts, plowing out roads that crisscross and loop and lady's-chain and lead nowhere--simply for the fun of it. Fairies do wonderful things and live in impossible castles; but no fairy ever had a palace in fairy-land more impossible than this unfairy-like meadow-mouse had in my back yard. One February day I broke through the frozen crust of earth in the garden and opened a large pit in which forty bushels of beets were buried. I took out the beets, and, when near the bottom, I came upon a narrow tunnel running around the wall of the pit like the Whispering Gallery around the dome of St. Paul's. It completely circled the pit, was well traveled, and, without doubt, was the corridor of some small animal that had the great beet-pit for a winter home. There were numerous dark galleries branching off from this main hallway, piercing out into the ground. Into one of these I put my finger, by way of discovery, thinking I might find the nest. I did find the nest--and more. The instant my finger entered the hole a sharp twinge shot up my arm, and I snatched away my hand with a large meadow-mouse fastened to the end of my finger, and clinging desperately to her, lo! two baby mice, little bigger than thimbles. In this mild and even temperature, four feet below the frozen surface of the garden, with never a care as to weather and provisions, dwelt this single family of meadow-mice. What a home it was! A mansion, indeed, with rooms innumerable, and a main hall girdling a very mountain of juicy, sugary beets. This family could not complain of hard times. Besides the beets, the mice had harvested for themselves a number of cribs of clover-roots. These cribs, or bins, were in the shape of little pockets in the walls of the great gallery. Each contained a cupful of the thick, meaty tap-roots of clover, cut into lengths of about half an inch. If the beets should fail (!), or cloy upon them, they had the roots to fall back on. It was absolutely dark here, and worse; there was no way to get fresh air that I could see. Yet here two baby mice were born in the very dead of winter, and here they grew as strong and warm and happy as they would have grown had the season showered rose-petals instead of snowflakes over the garden above.
