I had been suffering in my health a good deal all the way; and at last, whether I was exhausted by my complaint or poisoned in some wayside eating-house, the evening we left Laramie, I fell sick outright. That was a night which I shall not readily forget. The lamps did not go out; each made a faint shining in its own neighbourhood, and the shadows were confounded together in the long, hollow box of the car. The sleepers lay in uneasy attitudes; here two chums alongside, flat upon their backs like dead folk; there a man sprawling on the floor, with his face upon his arm; there another half seated with his head and shoulders on the bench. The most passive were continually and roughly shaken by the movement of the train; others stirred, turned, or stretched out their arms like children; it was surprising how many groaned and murmured in their sleep; and as I passed to and fro, stepping across the prostrate, and caught now a snore, now a gasp, now a half-formed word, it gave me a measure of the worthlessness of rest in that unresting vehicle. Although it was chill, I was obliged to open my window, for the degradation of the air soon became intolerable to one who was awake and using the full supply of life. Outside, in a glimmering night, I saw the black, amorphous hills shoot by unweariedly into our wake. They that long for morning have never longed for it more earnestly than I.
