Thoreau's Journal: 22-Jun-1851
As I walk the railroad causeway, I notice that the fields and meadows have acquired various tinges as the season advances, the sun gradually using all his paints. There is the rosaceous evening red tinge of red clover,—like an evening sky gone down under the grass,—the whiteweed tinge, the white clover tinge, which reminds me how sweet it smells. The tall buttercup stars the meadow on another side, telling of the wealth of dairies. The blue-eyed grass, so beautiful near at hand, imparts a kind of slate or clay blue tinge to the meads.
