A great painter is at work...Thoreau's Journal: 06-Oct-1857

Think what a change, unperceived by many, has within a month come over the landscape! Then the general, the universal, hue was green. Now see those brilliant scarlet and glowing yellow trees in the lowlands a mile off! I see them, too, here and there on the sides of hills, standing out distinct, mere bright and squads perchance, often in long broken lines, and so apparently elevated by their distinct color that they seem arranged like the remnants of a morning mist just retreating in a broken line along the hillsides. Or see that crowd in the swamp half a mile through, all vying one another, a blaze of glory. See those crimson patches far away on the hillsides, like dense flocks of crimson sheep, where the huckleberry reminds of recent excursions. See those patches of rich brown in the low grounds, where the ferns stand shriveled. See the greenish-yellow phalanxes of birches, and the crisped yellowish elm-tops here and there. We are not prepared to believe that the earth is now so parti-colored, and would present to a bird’s eye such distinct masses of bright yellow. A great painter is at work. The very pumpkins yellowing in the fields become a feature in the landscape, and thus they have shone, maybe, for a thousand years here.
