Willa Cather, The Song Of The Lark
She used to drag her mattress besider her low window and lie awake for a long while, vibrating with excitement, as a machine vibrates from speed. Life rushed in upon her through that window - or so it seemed. In reality, of course, life rushes from within, not from without. There is no work of art so big or so beautiful that is was not once all contained in some youthful body, like this one which lay on the floor in the moonlight, pulsing with ardor and anticipation.
