It was not the Fort Benton he had come far to see, so that on the second day he went away up the long hill that shut out the world and, until the east-bound train came from over the prairies, paced the depot platform impatiently with never a vision to keep him company. For a long time the gaze of Thurston clung fascinated to the wide prairie land, feeling again the stir in his blood. Then, when a deep cut shut from him the sight of the wilderness, he chanced to turn his head, and looked straight into the clear, blue-gray eyes of a girl across the aisle. Thurston considered himself immune from blue-gray--or any other-eyes, so that he permitted himself to regard her calmly and judicially, his mind reverting to the fact that he would need a heroine to be kidnapped, and wondering if she would do. She was a Western girl, he could tell that by the tan and by her various little departures from the Eastern styles--such as doing her hair low rather than high. Where he had been used to seeing the hair of woman piled high and skewered with many pins, hers was brushed smoothly back-smoothly save for little, irresponsible waves here and there. Thurston decided that the style was becoming to her. He wondered if the fellow beside her were her brother; and then reminded himself sagely that brothers do not, as a rule, devote their time quite so assiduously to the entertainment of their sisters. He could not stare at her forever, and so he gave over his speculations and went back to the prairies. Another hour, and Thurston was stiffing a yawn when the coaches bumped sharply together and, with wheels screeching protest as the brakes clutched them, the train, grinding protest in every joint, came, with a final heavy jar, to a dead stop. Thurston thought it was a wreck, until out ahead came the sharp crackling of rifles. A passenger behind him leaned out of the window and a bullet shattered the glass above his head; he drew back hastily. Some one hurried through the front vestibule, the door was pushed unceremoniously open and a man--a giant, he seemed to Thurston--stopped just inside, glared down the length of the coach through slits in the black cloth over his face and bawled, “Hands up!”
