in Thoreau’s Journal:
Clover begins to redden the fields generally. The quail is heard at a distance. Buttercups of various kinds mingled, yellow the meadows, the tall, the bulbous, the repens.
The cinquefoil, in its ascending state, keeping pace with the grass, is now abundant in the fields. Saw it one or two weeks ago. This is a feature of June. Still both high and low blueberry and huckleberry blossoms abound. The hemlock woods, their fanlike sprays edged or spotted with short, yellowish-green shoots, tier above tier, shelf above shelf, look like a cool bazaar of rich embroidered goods. How dense their shade, dark and cool, beneath them, as in a cellar. No plants glow there, but the ground is covered with fine red leaves. It is oftenest on a side hill they grow.
