in Thoreau’s Journal:

October must be the month of ripe & tinted leaves — Throughout November they are almost entirely withered & somber—the few that remain. In this month the sun is valued—when it shines warmer or brighter we are sure to observe it— There are not so many colors to attract the eye.

We begin to remember the summer. We walk fast to keep warm. For a month past I have sat by a fire.
