Two miles or so farther brought me to the end of all tokens of travel. The track had dwindled to less and less, and now had dropped to the bouldery bed of a canon stream, from which no woodcraft of mine, nor of my good trail-wise horse, could perceive that it made an exit. If the trail continued, it must follow the bed of the stream. At any rate, here was water, the first requisite for a camp; I decided to go on for a while, but to stick to the creek, for safety. Dismounting, I led Pancho forward by the bridle among the slippery boulders. The sun was well out of sight, and the chirping of crickets among the herbage announced that soon the evening shades would prevail. Evidently, camping was to be my portion, so I kept my eyes open for a good spot for the purpose. The canon appeared to widen out a little way ahead: there I should probably find good grazing for the horse (though not, I ruefully reflected, for myself). Arriving at the opening, I found, as I expected, grassy slopes rising from the creek, and resolved to make here my bivouac. Taking off saddle and bridle I turned Pancho loose to graze, while I gathered wood for afire. The dusk was soon enlivened by a crackling blaze, beside which I sat to eat a sandwich and a scrap of chocolate, reserving an equivalent banquet for the morning. Pancho munched away cheerfully, the stream tinkled and purred; the first star telegraphed its friendly signal down through the ether: to be lost in the Simi was not half bad. My supper (since it must be so called) over, and Pancho picketed for the night, I walked a short way up the canon in the gloaming. Some two hundred yards from camp, at a point where the stream made a turn, I stopped in sudden surprise at the sight of a light shining among a clump of small live-oaks near by to my right. "Well," I said to myself, "so I am on a trail, after all. Can there be a house here, too?" A few steps, and my question was answered, for I saw that the light shone through the open window of a little house of adobe. What should I do? My appearance at this lonely spot at night would cause so much surprise that I hesitated. But I was quite conscious that I had made an unduly light supper, and, moreover, that I was in the way of making no better a breakfast. Probably I could buy here a little food, and at any rate, I could get information as to my road: so I approached the house. There was an attempt at a garden, I saw, and growing against the window was a bush of the red-flowered sage which I have noted as being a general favorite with Mexicans. As I came up to the door I heard voices, and caught a glimpse through the window of a woman sitting at a rough table, eating. At the same moment a dog within the room started up and barked loudly. It seemed to be my cue to speak as well as knock, so, acting on a vague assumption that the people were Mexicans, I called, "Buenas noches!"
