in Thoreau’s Journal:
A comfortable breezy June morning. No dust to-day. To explore a segment of country between the Stow hills and the railroad in Acton, west to Boxboro. A fine, clear day, a journey day. A very small blue veronica in the bank by the roadside at Mrs. Hosmer’s, apparently the same with that I saw on the Cliffs with toothed leaves. Interesting from being blue. The traveller now has the creak of the cricket to encourage him on all country routes, out of the fresh sod, still fresh as in the dawn, not interrupting his thoughts. Very cheering and refreshing to hear so late in the day, this morning sound. The whiteweed colors some meadows as completely as the frosting does a cake. The waving June grass shows watered colors like grain. No mower’s scythe is heard. The farmers are hoeing their corn and potatoes. Some low blackberry leaves are covered with a sort of orange-colored mildew or fungus. The clover is now in its glory. Whole fields are rosed with it, mixed with sorrel, and looking deeper than it is. It makes fields look luxuriant which are really thinly clad. The air is full of its sweet fragrance. I cannot find the linnæa in Loring’s; perhaps because the woods are cut down; perhaps I am too late. The robins sing more than usual, maybe because of the coolness. Buttercups and geraniums cover the meadows, the latter appearing to float on the grass, – of various tints. It has lasted long, this rather tender flower. Methinks there are most tall buttercups now. These and the senecio, now getting stale, prevail in the meadows. Green early blueberries on hillsides passim remind you of the time when berries will be ripe. This is the ante-huckleberry season, when fruits are green. The green fruit of the thorn is conspicuous, and of the wild cherry and the amelanchiers and the thimble-berry. These are the clover days.
Maybe the huckleberry- bird best expresses the season, or the red-eye.
What subtle differences between one season and another! The warmest weather has, perchance, arrived and the longest days, but not the driest. When I remember gathering ripe blackberries on sandy fields or stones by the roadside, the very berries warmed by the sun, I am convinced of this. The seasons admit of infinite degrees in their revolutions. Found one of the purple orchises in an open meadow.
