Although our journey began at four o'clock in the morning it was two or three o'clock in the afternoon before we reached the welcome shelter of the next station, and it seemed to me from beginning to end one uninterrupted climb. This station on the Teboreachic was an exception to the rest on the trail regarding distance, for it is only eighteen miles from the Potrero, although eighteen miles of incessant uphill work. While the trail is by no means as steep or dangerous as that leading into the Urique barranca, it is fully as long a climb to reach the top or cumbra, and one does not welcome a retreat to the somber pines with half the enthusiasm inspired by a descent into the tropical foliage of the deep barrancas. I have already described so many ascents and descents, that carried us from one kind of climate to another, that I hardly think it necessary to repeat it in this instance. One feature of the ascent, however, exceptionally pleasant, was the ease with which one could get off one's tired mule and not only earn its gratitude, if a mule may be said to possess that virtue, but also stretch one's weary limbs by climbing over a comparatively good trail. As soon as we were well up in the mountains we found the region extremely well watered, beautiful streams flowing through every little glen or valley, many of them filled with small trout. This Batopilas trail differed from the other in that some attempt at grade had been made. It did not adopt the erratic Indian method of making for the top of every tall peak and then climbing down on the other side, only to repeat the performance until the rider became almost seasick from the undulations. Since Batopilas came into the hands of Americans there has been a constant effort on their part to look for better grades and secure a simpler method of ingress and egress from their mountain mines, and they are continually broadening and improving the path. Still, at the best, they can never make anything but a narrow mountain trail in that country of crag and cañon. The day will come when railways are built through that rich region, but until then the patient mule will be the only means of transportation.
