Thoreau writes in his journal:
I heard the what what what what of the nuthatch this forenoon. Do I ever hear it in the afternoon? It is much like the cackle of the pigeon woodpecker and suggests a relation to that bird.
Again I walk in the rain and see the rich yellowish browns of the moist banks. These Clamshell hills and neighboring promontories, though it is a dark and rainy day, reflect a certain yellowish light from the wet withered grass which is very grateful to my eyes . . .
