The tracks of the mice near the head of Well Meadow were particularly interesting. There was a level surface of pure snow there, unbroken by bushes or grass, about four rods across, and here were nine tracks of mice running across it from the bushes on this side to those on the other, the tracks quite near together but repeatedly crossing each other at very acute angles, but each particular course was generally quite direct. The snow was so light that only one distinct track was made by all four of the feet, five or six inches apart, but the tail left a very distinct mark. A single track, thus stretching away almost straight, sometimes half a dozen rods, over unspotted snow, is very handsome, like a chain of a new pattern; and then they suggest an airy lightness in the body that impressed them. Though there may have been but one or two here, the tracks suggesting quite a little company that had gone gadding over to their neighbors under the opposite bush. Such is the delicacy of the impression on the surface of the lightest snow, where other creatures sink, and night, too, being the season when these tracks are made, they remind me of a fairy revel. It is almost as good as if the actors were here. I can easily imagine all the rest. Hopping is expressed by the tracks themselves. Yet I should like much to see by broad daylight a company of these revellers hopping over the snow. There is a still life in America that is little observed or dreamed of. Here were possible auditors and critics which the lecturer at the Lyceum last night did not think of. How snug they are somewhere under the snow now, not to be thought of, if it were not for these pretty tracks! And for a week, or fortnight even, of pretty still weather the tracks will remain, to tell of the nocturnal adventures of a tiny mouse who was not beneath the notice of the Lord. So it was so many thousands of years before Gutenberg invented printing with his types, and so it will be so many thousands of years after his types are forgotten, perchance. The deer mouse will be printing on the snow of Well Meadow to be read by a new race of men.
