in Thoreau’s Journal:
It is so cool a morning that for the first time I move into the entry to sit in the sun. But in this cooler weather I feel as if the fruit of my summer were hardening and maturing a little, acquiring color and flavor like the corn and other fruits in the field. When the very earliest ripe grapes begin to be scented in the cool nights, then, too, the first cooler airs of autumn begin to waft my sweetness on the desert airs of summer. Now, too, poets nib their pens afresh. I scent their first-fruits in the cool evening air of the year. By the coolness the experience of the summer is condensed and matured, whether our fruits be pumpkins or grapes. Man, too, ripens with the grapes and apples.
