"How do I know? 'Cause I saw their pass before you was up this morning, cully. It's for Mrs. Captain Rayner and sister, and they're going out here to Fort Warrener. That's how I know." And the porter of the car had confirmed the statement in the sanctity of the smoking-room. And yet--such is the uncertainty of feminine temperament--Mrs. Rayner was no more incensed at the commercial "gent" because he had obtruded his attentions than she was at the young man reading in his own section because he had refrained. Nearly twenty-four hours had elapsed since they crossed the Missouri, and in all that time not once had she detected in him a glance that betrayed the faintest interest in her, or--still more remarkable--in the unquestionably lovely girl at her side. Intrusiveness she might resent, but indifference she would and did. Who was this youth, she wondered, who not once had so much as stolen a look at the sweet, bonny face of her maiden sister? Surely 'twas a face any man would love to gaze upon,--so fair, so exquisite in contour and feature, so pearly in complexion, so lovely in the deep, dark brown of its shaded eyes. The bold glances of the four card-players she had defiantly returned, and vanquished. Those men, like the travelling gents, were creatures of coarser mould; but her experienced eye told her the solitary occupant of the opposite section was a gentleman. The clear cut of his pale features, the white, slender hand and shapely foot, the style and finish of his quiet travelling-dress, the soft modulation and refined tone of his voice on the one occasion when she heard him reply to some importunity of the train-boy with his endless round of equally questionable figs and fiction, the book he was reading,--a volume of Emerson,--all combined to speak of a culture and position equal to her own. She had been over the trans-continental railways often enough to know that it was permissible for gentlemen to render their fellow-passengers some slight attention which would lead to mutual introductions if desirable; and this man refused to see that the opportunity was open to him.
