From "La Cumbra," or the crest of the Sierra Madres, we could look down in the valley of the Urique River, as I have said, something over a vertical mile. As we stood among the pines we could see the plantations of oranges far below, one of which, called "La Naranja"--the Spanish for orange--seemed almost under our feet; in fact it was not farther away in horizontal measure than it was vertical, or about a mile in both. The Barranca of the Urique was much more open at this point than where we had first struck it at Camp Diaz, but it was, nevertheless, fully as grand and sublime in its mighty scenery, although of quite another kind. The enormous buttresses, almost spurs of mountains, that stood out along the cañon-like sides of the former, with their bristling, perpendicular fronts of thousands of feet in height, were now rounded off along the ridges with their vertical descents, and only their sides were straight up and down. In fact it was down these steep ridges that we must make our descent by zigzag trails that gave us a grade on which a mule could stand. Every time we came to the side of a ridge the trail hung over a precipice with a sickening dizziness to the rider until the mule could make the turn and get back on the descending trail. Occasionally it was necessary to leave one ridge for another far away that gave a better grade, and then we might have to skirt some cumbra, or crest, with walls practically vertical on either side, where, if we ever started to fall, we could guarantee ourselves one thousand five hundred to two thousand feet of plain sailing. On the trail from Batopilas to Parral is the "La Infinitad" of the Mexican miners (the Infinity), where the trail, not over half a foot wide, looks down a sheer vertical twenty-six hundred feet.
