All day the heavy train of sleepers had been climbing the long rise from the river-a monotonous stretch of treeless, short-grass plains reaching from the Missouri to the mountains. And now the train stopped again, almost noiselessly. Kate, with the impatience of girlish spirits tried by a long and tedious car journey, left her Pullman window and its continuous, one-tone picture, and walking forward was glad to find the vestibule open. The porter, meditating alone, stood below, at the car step, looking ahead; Kate joined him. The stop had been made at a lonely tank, for water. No human habitation was anywhere in sight. The sun had set. For miles in every direction the seemingly level and open country spread around her.

She looked back to the darkening east that she was leaving behind. It suggested nothing of interest beyond the vanishing perspective of a long track tangent. Then to the north, whence blew a cool and gentle wind, but the landscape offered nothing attractive to her eyes; its receding horizon told no new story. Then she looked into the west.
