in Thoreau’s Journal:

It began to snow again last evening, but soon ceased, and now it has turned out a fine winter morning, with half an inch of snow on the ground, the air full of mist, through which the smokes rise up perfectly straight; and the mist is frozen in minute leafets on the fences and trees and the needles of the pines, silvering them.

I stood by Bigelow the blacksmith’s forge yesterday, and saw him repair an axe. He burned the handle out, then, with a chisel, cut off the red-hot edge even, there being some great gaps in it, and by hammering drew it out and shaped it anew, —all in a few minutes. It was interesting to see performed so simply and easily, by the aid of fire and a few rude tools….

P. M. — To Pink Azalea Woods.

The warm sun has quite melted the thin snow on the south sides of the hills, but I go to see the tracks of animals that have been out on the north sides. First, getting over the wall under the walnut trees on the south brow of the hill, I see the broad tracks of squirrels, probably red, where they have ascended and descended the trees, and the empty shells of walnuts which they have gnawed left on the snow. The snow is so very shallow that the impression of their toes is the more distinctly seen. It imparts life to the landscape to see merely the squirrels’ track in the snow at the base of the walnut tree. You almost realize a squirrel at every tree. The attractions of nature are thus condensed or multiplied. You see not merely bare trees and ground which you might suspect that a squirrel had left, but you have this unquestionable and significant evidence that a squirrel has been there since the snow fell, — as conclusive as if you had seen him.

A little further I heard the sound [of] a downy wood- pecker tapping a pitch pine in a little grove, and saw him inclining to dodge behind the stem. He flitted from pine to pine before me. Frequently, when I pause to listen, I hear this sound in the orchards or streets. This was in one of these dense groves of young pitch pines.

Suddenly I heard the screwing mew and then the whir of a partridge on or beneath an old decaying apple tree which the pines had surrounded. There were several such, and another partridge burst away from one. They shoot off swift and steady, showing their dark-edged tails, almost like a cannon-ball. I saw one’s track under an apple tree and where it had pecked a frozen-thawed apple.

Then I came upon a fox-track made last night, leading toward a farmhouse, —Wheeler’s, where there are many hens, — running over the side of the hill parallel with Wheeler’s new wall. He was dainty in the choice of his ground, for I observed that for a mile he had adhered to a narrow cow-path, in which the snow lay level, for smoothness. Sometimes he had cantered, and struck the snow with his foot between his tracks. Little does the farmer think of the danger which threatens his hens.

In a little hollow I see the sere gray pennyroyal rising above the snow, which, snuffed, reminds me of garrets full of herbs. 

Now I hear, half a mile off, the hollow sound of woodchopping, the work of short winter days begun, which is gradually laying bare and impoverishing our landscape. In two or three thicker woods which I have visited this season, I was driven away by this ominous sound.

Further over toward the river, I see the tracks of a deer mouse on a rock, which suddenly come to an end where apparently it had ascended a small pine by a twig which hung over it. Sometimes the mark of its tail was very distinct. Afterwards I saw in the pasture westward where many had run about in the night. In one place many had crossed the cow-path in which I was walking, in one trail, or the same one had come and gone many times. In the large hollows where rocks have been blasted, and on the sides of the river, I see irregular spaces of dark ice bare of snow, which was frozen after the snow ceased to fall. But this ice is rotten and mixed with snow. I am surprised to see the river frozen over for the most part with this thin and rotten snow ice, and the drooping or bent alders are already frozen into this slush, giving to the stream a very wintry aspect. I see some squirrel-tracks about a hole in a stump.

At the azalea meadow or swamp, the red tops of the osiers, which are very dense and of a uniform height, are quite attractive, in the absence of color at this season. Any brighter and warmer color catches our eye at this season. I see an elm there whose bark is worn quite smooth and white and bare of lichens, showing exactly the height at which the ice stood last winter.

Looking more closely at the light snow there near the swamp, I found that it was sprinkled all over (as with pellets of cotton) with regular star-shaped cottony flakes with six points, about an eighth of an inch in diameter and on an average a half an inch apart. It snowed geometry. 

How snug and warm a hemlock looks in the winter!

That by the azalea looks thus: There is a tendency in the limbs to arrange themselves ray-wise about a point one third from the base to the top. What singular regularity in the outline of a tree!

I noticed this morning successive banks of frost on the windows, marked by their irregular waving edges, like the successive five, ten, and fifteen fathom lines which mark the depth of the shores on charts.

Thus by the snow I was made aware in this short  walk of the recent presence there of squirrels, a fox, and countless mice, whose trail I had crossed, but none of which I saw, or probably should have seen before the snow fell. Also I saw this afternoon the track of one sparrow, probably a tree sparrow, which had run among the weeds in the road.
