In addition to his alarm, Ridge was overcome with a guilty knowledge of having fallen asleep while on guard. Of course, he felt certain that he had only closed his eyes for a minute; but in that minute something dreadful, for which he was responsible, had happened. He had no idea what it was, but imagined the worst, and was greatly relieved to hear the voice of his prisoner-comrade at his side. "What on earth--" he began; but just then Senorita dashed up to him in a state of terror, and for the moment demanded his attention. As he soothed her he called loudly for Dionysio, but there was no response. "I am afraid he has escaped," said the young Spaniard, in rather a faint voice, from the ground, to which he had dropped exhausted by weakness and the intense strain of the past few hours. "He tried to kill me, you know." "Tried to kill you!" exclaimed Ridge, incredulously. "But wait a moment. We must have a light. This darkness is awful." Thus saying, he stepped to where a few coals of the camp-fire still smouldered, and began to throw on sticks, which, after a little coaxing, sprang into a bright blaze. By its light he detected two dark forms lying motionless a short distance away, and, with pistol held ready for action, went to discover their nature. "Navarro must have been dreaming, or else greatly mistaken," he said to himself, "for here is Dionysio fast asleep. Come, wake up!" he cried aloud, at the same time prodding the prostrate form with his toe. As there was no response, he stooped to give the sleeper a vigorous shaking; but almost with the first touch he sprang back in horror. The man lay on his back, but with his head so twisted about that only its rear portion was visible, and Ridge instinctively knew that he was dead. The other motionless form was that of a dead horse, the one recently ridden by Lieutenant Navarro. Having made this ghastly discovery, Ridge hastily returned to the hut to gain from his companion an explanation of what had happened, "I could not sleep," said the young Spaniard, in answer to his inquiries, "though I lay still and tried hard to do so, until, by your heavy breathing, I discovered that you were no longer awake." "I am awfully ashamed of myself," said Ridge. "It is not to be wondered at," rejoined the other, consolingly. "You had not so much at stake as I, for only my life was threatened. Somehow, I felt certain that the black fiend who thirsted for my blood was also lying awake, and would make an attempt to kill me in my hammock before morning. So, without disturbing you, I moved to the back of the hut and waited for him. It must have been an hour before the horses began to give signs of great uneasiness, and then one of them fell. I suppose he must have killed it." "Yes," said Ridge, "I reckon he did, since it now lies dead, and bleeding from a stab behind the left fore-shoulder."
