With the confidence of a child she accepted my arrangement and on the first day of July we were in the stage ambling across the hot, dry prairie which lay between Bismark and Fort Yates. Empty, arid and illimitable the rolling treeless landscape oppressed us both, and yet there was a stern majesty in its sweep, and the racing purple shadows of the dazzling clouds lent it color and movement. To me it was all familiar, but when, after an all-day ride, we came down into the valley of the Muddy Missouri, the sheen of its oily red current was quite as grateful to me as to my weary wife. Our only means of reaching the Agency was a small rowboat which seemed a frail ferry even to me. How it appeared to Zulime, I dared not ask--but she unhesitatingly stepped in and took her seat beside me. I think she accepted it as a part of the strange and hardy world in which her husband was at home. We were both silent on that crossing, for our slender craft struggled anxiously with the boiling, silent, turbid current, and when we landed, the tense look on Zulime's face gave place to a smile.--Half an hour later we were sitting at supper in a fly-specked boarding house, surrounded by squaw-men and half-breed Sioux, who were enjoying the luxury of a white man's table as a part of their Fourth of July celebration. My artist wife was being educated swiftly! The tribe was again encamped in a wide circle just west of the Fort, precisely as when my brother and I had visited it three years before, while the store and the Agency swarmed with native men and women, many in mixed costume of cloth and skin. Zulime's artistic joy in them filled me with complacent satisfaction. I had the air of a showman rejoicing in his exhibition hall. With keen interest we watched the young warriors as they came whirling in on their swift ponies, each in his gayest garments, the tail of his horse decorated with rosettes and ribbons. Possessing the swiftness and the grace of Centaurs, coming and going like sudden whirlwinds, they were superb embodiments of a race which was passing. Some of the older men remembered me, and greeted me as one friendly to their cause--but for the most part the younger folk eyed us with indifference. That night a singular and savage change in the weather took place. The wind shifted to the southeast and took on the heat of a furnace. By ten o'clock next morning dirt was blowing in clouds and to walk the street was an ordeal. All day Zulime remained in her room virtually a prisoner. Night fell with the blast still roaring, and the dust rising from the river banks like smoke, presented a strange and sinister picture of wrath. It was as though the water, itself, had taken fire from the lightning which plunged in branching streams across the sky. Thunder muttered incessantly all through that singular and solemn night, a night which somehow foreshadowed the doom which was about to overtake the Sioux.
