Thoreau writes in his journal:
Huckleberry-apples, which are various stages of a monstrous and abortive development of the flower, common now. Clover begins to redden the fields generally. The horsetail has for some time covered the causeway with a close, dense green, like moss. The
quail is heard at a distance. The marsh speedwell has been out apparently some days. A little mowing begins in the gardens and front yards. The grass is in full vigor now, yet it is already parti-colored with whitish withered stems which worms have cut. Buttercups, of various kinds mingled, yellow the meadows,—the tall, the bulbous, and the repens. Probably a Prinos lcevigatus in Trillium Woods, ready to blossom.
