"And I went outside the post the night after you left, down to the river. Some one will probably tell you about a wounded Sierra Blanca found down among the bushes in the river bottom that same night. I shot him, and then I hacked him up with my knife." He had taken his pipe from his mouth and was looking at her incredulously, perplexed. He did not understand whether it was a joke on her part, or exactly what it was. But she sat up suddenly, with one of her quick movements of conscious strength and perfect control over every muscle, clasped her hands about her knees, and went on. "It was very curious," and there came on her face the watchful, alert, wild look, with the narrowing of the eyes. "It was very curious, I could not have stayed indoors that night if it had cost me my life--and it very nearly did, too. I had to get out. So I took my revolver and my knife, and I went the back way, down to the river. While I was standing on the bank and thinking about going home, an Indian stole out on me. I had an awful struggle. First I shot. I aimed at his forehead, but the bullet struck his shoulder; and then I fought with the knife. As soon as I could slip out of his grasp, I went at him and drove him off. But I didn't know how badly he was hurt until the next day. The shot had roused them up here, and they went down to the river and found him bleeding on the sand. "They put him in a tent beside the hospital, and the next morning I went over with the doctor to see him. He was all cut up on the arms and neck and shoulders. I must have been very strong." She stopped, and he still sat with the puzzled look on his face, but a light of understanding beginning to show through. "Are you joking," he asked, "or what?" "Indeed, I am not joking," she assured him earnestly. "It is quite true. Ask any one. Only don't let them know it was I who wounded him. They have never so much as suspected it. Fortunately I thought of you and ran home all the way, and was in my tent before it occurred to any one to come for me." She burst into a low laugh at his countenance of wrath and dismay. "Oh! come, Jack dear, it is not so perfectly, unspeakably horrible after all. I was disobedient. But then I am so sorry and promise never, never to do it again." "You might have killed the Indian," he said, in a strained voice. It did not occur to either of them, just then, that it was not the danger she had been in that appalled him. She was astonished in her turn. "Killed him! Why, of course I might have killed him," she said blankly, frowning, in a kind of hopeless perplexity over his want of understanding. "I came very near it, I tell you. The ball made shivers of his shoulder. But he was brave," she grew enthusiastic now, "he let the doctor probe and pick, and never moved a muscle. Of course he was half drunk with tizwin, even then." "You didn't stay to see the operation?" His voice was ominously quiet.
