The reasons are easy to define. All my emotional relationships with the "High Country" were pleasant, my sense of responsibility was less keen, hence the notes of resentment, of opposition to unjust social conditions which had made my other books an offense to my readers were almost entirely absent in my studies of the mountaineers. My pity was less challenged in their case. Lonely as their lives were, it was not a sordid loneliness. The cattle rancher was at least not a drudge. Careless, slovenly and wasteful as I knew him to be, he was not mean. He had something of the Centaur in his bearing. Marvelous horsemanship dignified his lean figure and lent a notable grace to his gestures. His speech was picturesque and his observations covered a wide area. Self-reliant, fearless, instant of action in emergency, his character appealed to me with ever-increasing power. I will not say that I consciously and deliberately cut myself off from my prairie material, the desertion came about naturally. Swiftly, inevitably, the unplowed valleys, the waterless foothills and the high peaks, inspired me, filled me with desire to embody them in some form of prose, of verse. Laden with a myriad impressions of Indians, mountaineers and miners, I returned to my home as a bee to its hive, and there, during October, in my quiet chamber worked fast and fervently to transform my rough notes into fiction. Making no attempt to depict the West as some one else had seen it, or might thereafter see it, I wrote of it precisely as it appeared to me, verifying every experience, for, although I had not lingered long in any one place--a few weeks at most--I had observed closely and my impressions were clearly and deeply graved. In fear of losing that freshness of delight, that emotion which gave me inspiration, I had made copious notes while in the field and although I seldom referred to them after I reached my desk, the very act of putting them down had helped to organize and fix them in my mind. All of September and October was spent at the Homestead. Each morning I worked at my writing, and in the afternoon I drove my mother about the country or wrought some improvement to the place. * * * * * In the midst of these new literary enthusiasms I received a message which had a most disturbing effect on my plans. It was a letter from Sam McClure whose new little magazine was beginning to show astonishing vitality. "I want you to write for me a life of Ulysses Grant. I want it to follow Ida Tarbell's _Lincoln_ which is now nearing an end. Come to New York and talk it over."
