At intervals during the tragedy, and afterward as we rode homeward, we heard the roar of Lobo as he wandered about on the distant mesas, where he seemed to be searching for Blanca. He had never really deserted her, but, knowing that he could not save her, his deep-rooted dread of firearms had been too much for him when he saw us approaching. All that day we heard him wailing as he roamed in his quest, and I remarked at length to one of the boys, "Now, indeed, I truly know that Blanca was his mate." As evening fell he seemed to be coming toward the home canyon, for his voice sounded continually nearer. There was an unmistakable note of sorrow in it now. It was no longer the loud, defiant howl, but a long, plaintive wail; "Blanca! Blanca!" he seemed to call. And as night came down, I noticed that he was not far from the place where we had overtaken her. At length he seemed to find the trail, and when he came to the spot where we had killed her, his heartbroken wailing was piteous to hear. It was sadder than I could possibly have believed. Even the stolid cowboys noticed it, and said they had "never heard a wolf carry on like that before." He seemed to know exactly what had taken place, for her blood had stained the place of her death. Then he took up the trail of the horses and followed it to the ranch-house. Whether in hopes of finding her there, or in quest of revenge, I know not, but the latter was what he found, for he surprised our unfortunate watchdog outside and tore him to little bits within fifty yards of the door. He evidently came alone this time, for I found but one trail next morning, and he had galloped about in a reckless manner that was very unusual with him. I had half expected this, and had set a number of additional traps about the pasture. Afterward I found that he had indeed fallen into one of these, but, such was his strength, he had torn himself loose and cast it aside. I believed that he would continue in the neighborhood until he found her body at least, so I concentrated all my energies on this one enterprise of catching him before he left the region, and while yet in this reckless mood. Then I realized what a mistake I had made in killing Blanca, for by using her as a decoy I might have secured him the next night.
