Still another very cold morning.

January 25. 

Still another very cold morning. Smith's thermometer over ours at -29°, ours in bulb; but about seven, ours was at -8° and Smith's at -24; ours therefore at first about -23°. 

P. M. — To Bittern Rock on river. 

The road beyond Hubbard's Bridge has been closed by snow for two or three weeks; only the walls show that there has been a road there. Travellers take to the fields. 

I see the track of a fox or dog across the meadow, made some time ago. Each track is now a pure white snowball rising three inches above the surrounding surface, and this has formed a lee behind which a narrow drift has formed, extending a foot or two south easterly.

H. D. Thoreau, Journal, January 25, 1857

Still another very cold morning. See January 25, 1852 (The cold for some weeks has been intense""); January 25, 1854 ("A very cold day . . .The 22d, 23d, 24th, and 25th of this month have been the coldest spell of weather this winter."); January 25, 1856 ("The hardest day to bear that we have had, for, beside being 5° at noon and at 4 P. M., there is a strong northwest wind. It is worse than when the thermometer was at zero all day. "); See also January 23, 1857 (The coldest day that I remember recording.").

Each track is now a pure white snowball rising three inches above the surrounding surface. See  January 8, 1860 (" Those [tracks] of the fox which has run along the side of the pond are now so many snowballs, raised as much above the level of the water-darkened snow as at first they sank beneath it. The snow, having been compressed by their weight, resists the melting longer. . . .There are a man's tracks, perhaps my own, along the pond-side there . . . like white stepping-stones"); January 12, 1854 ("I see my snowshoe tracks quite distinct, though made January 2d. Though they pressed the snow down four or five inches, they consolidated it, and it now endures and is two or three inches above the general level there, and more white.");
