He bandaged the wound as best he could with dressings torn from his shirt. He tried to stand, and found that the loss of so much blood had sapped his strength to a surprising degree. He could, however, support his weight by the aid of his horse. His mind was clearer. He found himself trying to analyze the events that had led up to the massacre, while his eyes studied the Gap. Why had the Texas Rangers been sent for? If they were not wanted in Bryant's Basin, it would have been a simple matter to have ignored them as had always been done in the past. Someone had sent for the Texas Rangers. Someone had objected with bullets to their coming. Did outlaws actually live in Bryant's Basin? If so, why were they there? Why had the Rangers been sent for? What could possibly happen in the Cavendish domain that the stern old man could not handle himself? These, and countless other questions, raced through the Ranger's brain while he continued to observe the Gap. He noted that the sun was gone, and it was growing dark. This left him in less danger of capture, but increased the difficulty of the ride. The rocky footing was hazardous under the best of conditions. In the dark, this peril was increased tenfold. He remounted after a struggle with weakness. At first he tried to guide the horse away from Bryant's Basin, but this seemed only to confuse the beast, so he gave up the attempt and let Silver have his head. At intervals he was compelled to steady himself like a drunken man. A starless night fell into the Gap, and with its coming the danger of pursuit was ended. A chance encounter was all the rider had to fear, and there was little likelihood of this. For a while his mind went blank. He was roused from a sort of stupor by the sound of running water. The horse had halted, while the Texas Ranger dozed, and was drinking from a creek. A sudden uncontrollable thirst assailed the man. Once more he climbed painfully from the saddle. Slumping to the ground, he crawled toward a stream that gurgled over stones. Cold water had never tasted sweeter. He sipped slowly, then raised his head to let the cool draft quench the burning in his throat. About to drink again, he paused and grew tense. The sound he heard might have been a night bird, but the trained ear of the Ranger detected a peculiar quality in it. "Odd," he thought. "That sounded as if it came from a human throat." He waited to catch the next call if it were repeated. He didn't see that Silver, too, was tense. The birdlike trill sounded again, nearer this time. The horse reacted unexpectedly to the call. Silver jerked back, and the reins slipped from the wounded man's hand. While he watched in consternation, the white horse scampered off in the direction of the sound.
