Such were his simple instructions as he headed my horse toward the canyon. But as I drew off, he shouted out: “If you get stuck, leave it to the horse. He knows more about it than you do.” With a vague gesture toward the northwest, he turned away, leaving me in contemplation of the grandest scenery I had yet come upon in all my travels. Fifteen miles! but those miles lay through the very heart of the mountains, ranging anywhere from six to seven thousand feet high. In ten minutes the city and all signs of city life were out of sight. In five more I was seemingly as far removed from all civilization as if I had gone a hundred miles into the wilderness. As my horse settled down to work, picking his way, now here and now there, sometimes over the brown earth, hard and baked as in a thousand furnaces, and sometimes over the stunted grass whose needle-like stalks seemed never to have known moisture, I let my eyes roam to such peaks as were not cut off from view by the nearer hillsides, and wondered whether the snow which capped them was whiter than any other or the blue of the sky bluer, that the two together had the effect upon me of cameo work on a huge and unapproachable scale. Certainly the effect of these grand mountains, into which you leap without any preparation from the streets and market-places of America’s oldest city, is such as is not easily described. We struck water now and then,—narrow water—courses which my horse followed in mid stream, and, more interesting yet, goatherds with their flocks, Mexicans all, who seemed to understand no English, but were picturesque enough to look at and a welcome break in the extreme lonesomeness of the way. I had been told that they would serve me as guides if I felt at all doubtful of the trail, and in one or two instances they proved to be of decided help. They could gesticulate, if they could not speak English, and when I tried them with the one word Placide they would nod and point out which of the many side canyons I was to follow. But they always looked up as they did so, up, up, till I took to looking up, too, and when, after miles multiplied indefinitely by the winding of the trail, I came out upon a ledge from which a full view of the opposite range could be had, and saw fronting me, from the side of one of its tremendous peaks, the gap of a vast hole not two hundred feet from the snowline, I knew that, inaccessible as it looked, I was gazing up at the opening of Abner Fairbrother’s new mine,
