Thoreau writes in his journal:
I find that I can see the sun set from almost any hill in Concord, and some within the confines of the neighboring towns, and though this takes place at just about 5 P.M., when the cows come in, get to the post-office by the time the mail is distributed. See the sun rise or set if possible each day. Let that be your pill. How speedily the night comes on now! There is duskiness in the afternoon light before you are aware of it, the cows have gathered about the bars, waiting to be let out, and, in twenty minutes, candles gleam from distant windows, and the walk for this day is ended . . .
