“I left for Taos, in New Mexico, taking with me the blank sheets for a fresh start on the book (the swimmer who plunges into the water with no assurance that he will reach the other shore). Closed inside my compartment as if in a cubicle of some Egyptian tomb, I worked late into the night between New York and Chicago; then all the next day, in the restaurant of a Chicago station where I awaited a train blocked by storms and snow; then again until dawn, alone in the observation car of a Santa Fe limited, surrounded by black spurs of the Colorado mountains, and by the eternal pattern of the stars. Thus were written at a single impulsion the passages on food, love, sleep, and the knowledge of men. I can hardly recall a day spent with more ardor, or more lucid nights.”
