AMS in pencil, titled and signed at the head, "Colorado Trails by Zane Grey," written on both sides of 49 sheets for a total of 98 pages, including fourteen 7.75 x 12.25 sheets and thirty-five 4.5 x 7.25 sheets, no date but circa 1918. Grey's original handwritten draft for a piece first published in the June 1918 issue of Outdoor Life magazine, and also collected in Grey's 1922 book Tales of Lonely Trails. The work begins: "Riding and tramping trails would lose half their charm if the motive were only to hunt and to fish. It seems fair to warn the reader who longs to embark upon a bloody game hunt or a chronicle of fishing records that this is not that kind of story. But it will be one for those who love horses and dogs, the long winding dim trails, the wild flowers and the dark still woods, the fragrance of spruce and the smell of camp-fire smoke. And as well for those who love to angle in brown lakes or rushing brooks or chase after the baying hounds or stalk the stag on his lonely heights." Grey makes extensive deletions and revisions throughout, lending great insight into his creative process. In overall fine condition.
