In the locomotive cab, gazing ahead with strained eyes, were the engine-driver, Luke Matherson, and his fireman. Every now and then the latter found a change of occupation in flinging open the furnace door and tossing chunk after chunk of wood into the glowing interior. As he closed the door he would stand for a moment and look inquiringly at his companion, who sat motionless, with his hand on the throttle, and his eyes fixed steadily on the lines of track gleaming in the light of the powerful headlight. Occasionally, without turning his head, he exchanged a few words with the fireman.
