in Thoreau’s Journal:

The small scull cap & cress & the mullein still in bloom. I see pigeon woodpeckers oftener now with their light rears. Birches & elms begin to turn yellow—& ferns are quite yellow or brown in many places. I see many tall clustered bluish asters by the brooks like the A undulatus. The blue stemmed golden rod is abundant bright & in its prime. The maples begin to be ripe. How beautiful when a whole maple on the edge of a swamp is like one great scarlet fruit—full of ripe juices— A sign of the ripening—every leaf from lowest limb to topmost spire— is a-glow. The woodbine is red too & its berries are blueing. The flattened black berries of the cucumber root—with the triangular bases of its leaves tinged red beneath as a sort of cup for them. My red ball fungus blossoms in the path in the midst of its jelly. As I was walking through the maple swamp by the Corner spring I was surprised to see apples on the ground—and at first supposed that some body had dropped them, but looking up I detected a wild apple tree, as tall and slender as the young maples and not more than 5 inches in diameter at the ground. This had blossomed & borne fruit this year— The apples were quite mellow & of a very agreeable flavor—they they had a rusty scraperish look—and I filled my pockets with them. The squirrels had found them out before me. It is an agreeable surprise to find in the midst of a swamp so large and edible a fruit as an apple. Of late we have much cloudy weather without rain. Are not liable to showers as in summer—but may have a storm. The lentago berries appear to drop off before or as soon as they turn. There are few left on the bushes. Many that I bring home will turn in a single night. The sassafras leaves are red. The huckleberry bushes begin to redden. The white actaea berries still hang on—or their red pedicels remain.
