in Thoreau’s Journal:

I turn Anthony’s corner. It is an early September afternoon, melting warm and sunny; the thousands of grasshoppers leaping before you reflect gleams of light; a little distance off the field is yellowed with a Xerxean army of Solidago nemoralis  between me and the sun; the earth-song of the cricket comes up through all; and ever and anon the hot z-ing of the locust is heard. (Poultry is now fattening on grasshoppers.)

The dry deserted fields are one mass of yellow, like a color shoved to one side on Nature’s palette. You literally wade in yellow flowers knee-deep, and now the moist banks and low hollows are beginning to be abundantly sugared with Aster Tradescanti.
