But not to sleep. Perhaps the responsibility towards these solitary children, which Johnson had so lightly shaken off, devolved upon me as I lay there, for I found myself imagining a dozen emergencies of their unprotected state, with which the elder girl could scarcely grapple. There was little to fear from depredatory man or beast--desperadoes of the mountain trail never stooped to ignoble burglary, bear or panther seldom approached a cabin--but there was the chance of sudden illness, fire, the accidents that beset childhood, to say nothing of the narrowing moral and mental effect of their isolation at that tender age. It was scandalous in Johnson to leave them alone. In the silence I found I could hear quite distinctly the sound of their voices in the extension, and it was evident that Caroline was putting them to bed. Suddenly a voice was uplifted--her own! She began to sing and the others to join her. It was the repetition of a single verse of a well-known lugubrious negro melody. “All the world am sad and dreary,” wailed Caroline, in a high head-note, “everywhere I roam.” “Oh, darkieth,” lisped the younger girl in response, “how my heart growth weary, far from the old folkth at h-o-o-me.” This was repeated two or three times before the others seemed to get the full swing of it, and then the lines rose and fell sadly and monotonously in the darkness. I don't know why, but I at once got the impression that those motherless little creatures were under a vague belief that their performance was devotional, and was really filling the place of an evening hymn. A brief and indistinct kind of recitation, followed by a dead silence, broken only by the slow creaking of new timber, as if the house were stretching itself to sleep too, confirmed my impression. Then all became quiet again. But I was more wide awake than before. Finally I rose, dressed myself, and dragging my stool to the fire, took a book from my knapsack, and by the light of a guttering candle, which I discovered in a bottle in the corner of the hearth, began to read. Presently I fell into a doze. How long I slept I could not tell, for it seemed to me that a dreamy consciousness of a dog barking at last forced itself upon me so strongly that I awoke. The barking appeared to come from behind the cabin in the direction of the clearing where I had tethered Chu Chu. I opened the door hurriedly, ran round the cabin towards the hollow, and was almost at once met by the bulk of the frightened Chu Chu, plunging out of the darkness towards me, kept only in check by her reata in the hand of a blanketed shape slowly advancing with a gun over its shoulder out of the hollow. Before I had time to recover from my astonishment I was thrown into greater confusion by recognizing the shape as none other than Caroline!
