Thoreau writes in his journal:
3 P.M.—Down the railroad.
Cloudy but springlike. When the frost comes out of the ground, there is a corresponding thawing of the man. The earth is now half bare. These March winds, which make the woods roar and fill the world with life and bustle, appear to wake up the trees out of their winter sleep and excite the sap to flow. I have no doubt they serve sonic such use, as well as to hasten the evaporation of the snow and water.
