"The train tore along with an angry, irregular rhythm. It was having to stop at smaller, more frequent stations, where it would wait impatiently for a moment, then attack prairie again. The process was imperceptible. The prairie only undulated. like a vast, pink-tan blanket being casually shaken. The faster the train went, the more buoyant and taunting the undulations."
