"I saw them to-day," he said, "and the wild one that breaks away is Blanca." Then the truth dawned upon me, and I added, "Now, I know that Blanca is a she-wolf, because were a he-wolf to act thus, Lobo would kill him at once." This suggested a new plan. I killed a heifer, and set one or two rather obvious traps about the carcass. Then cutting off the head, which is considered useless offal, and quite beneath the notice of a wolf, I set it a little apart and around it placed six powerful steel traps properly deodorized and concealed with the utmost care. During my operations I kept my hands, boots, and implements smeared with fresh blood, and afterward sprinkled the ground with the same, as though it had flowed from the head; and when the traps were buried in the dust I brushed the place over with the skin of a coyote, and with a foot of the same animal made a number of tracks over the traps. The head was so placed that there was a narrow passage between it and some tussocks, and in this passage I buried two of my best traps, fastening them to the head itself. Wolves have the habit of approaching every carcass they get the wind of, in order to examine it, even when they have no intention of eating it, and I hoped that this habit would bring the Currumpaw pack within reach of my latest stratagem. I did not doubt that Lobo would detect my handiwork about the meat, and prevent the pack approaching it, but I did build some hopes on the head, for it looked as though it had been thrown aside as useless. Next morning, I sallied forth to inspect the traps, and there, oh, joy! were the tracks of the pack, and the place where the beef-head and its traps had been was empty. A hasty study of the trail showed that Lobo had kept the pack from approaching the meat, but one, a small wolf, had evidently gone on to examine the head as it lay apart and had walked right into one of the traps. We set out on the trail, and within a mile discovered that the hapless wolf was Blanca. Away she went, however, at a gallop, and although encumbered by the beef-head, which weighed over fifty pounds, she speedily distanced my companion who was on foot. But we overtook her when she reached the rocks, for the horns of the cow's head became caught and held her fast. She was the handsomest wolf I had ever seen. Her coat was in perfect condition and nearly white. She turned to fight, and raising her voice in the rallying cry of her race, sent a long howl rolling over the cañon. From far away upon the mesa came a deep response, the cry of Old Lobo. That was her last call, for now we had closed in on her, and all her energy and breath were devoted to combat.
