Although my _Ulysses Grant, His Life and Character_ absorbed most of my time and the larger part of my energy during two years, I continued to dream (in my hours of leisure), of the "High Country" whose splendors of cloud and peak, combined with the broad-cast doings of the cattleman and miner, had aroused my enthusiasm. The heroic types, both white and red, which the trail has fashioned to its needs continued to allure me, and when in June, '97, my brother, on his vacation, met me again at West Salem, I outlined a tour which should begin with a study of the Sioux at Standing Rock and end with Seattle and the Pacific Ocean. "I must know the North-west," I said to him. In order to report properly to any army post, I had in my pocket a letter from General Miles which commended me to all agents and officers, and with this as passport I was in the middle of getting my equipment in order when Ernest Thompson Seton and his wife surprised me by dropping off the train one morning late in the month. They too, were on their way to the Rockies, and in radiant holiday humor. My first meeting with Seton had been in New York at a luncheon given for James Barrie only a few months before, but we had formed one of those instantaneous friendships which spring from the possession of many identical interests. His skill as an illustrator and his knowledge of wild animals had gained my admiration but I now learned that he knew certain phases of the West better than I, for though of English birth he had lived in Manitoba for several years. We were of the same age also, and this was another bond of sympathy. He asked me to accompany him on his tour of the Yellowstone but as I had already arranged for a study of the Sioux, and as his own plans were equally definite, we reluctantly gave up all idea of camping together, but agreed to meet in New York City in October to compare notes. The following week, on the first day of July, my brother and I were in Bismark, North Dakota, on our way to the Standing Rock Reservation to witness the "White Men's Big Sunday," as the red people were accustomed to call the Fourth of July. It chanced to be a cool, sweet, jocund morning, and as we drove away, in an open buggy, over the treeless prairie swells toward the agency some sixty miles to the south, I experienced a sense of elation, a joy of life, a thrill of expectancy, which promised well for fiction. I knew the signs.
