" Summer is the season of motion, winter is the season of form. In summer everything moves save the fixed and inert. Down the hill flows the west wind, making wavelets in the shorter grass and great billows in the standing hay; the tree in full leaf sways its heavy boughs below and tosses its leaves above; the weed by the gate bends and turns when the wind blows down the road. It is the shadow of moving things that we usually see, and the shadows are themselves in motion. The shadow of a branch, speckled through with light, wavers across the lawn, the sprawling shadow of the weed moves and sways across the dust. "
