The cold December moon is just showing above the tree-tops, pointing a white finger here and there at the clustered teepees of the Sioux, while opposite their winter camp on the lake shore a lonely, wooded island is spread like a black buffalo robe between the white, snow-covered ice and the dull gray sky. All by itself at the further end of the village stands the teepee of Smoky Day, the old story-teller, the school-master of the woods. The paths that lead to this low brown wigwam are well beaten; deep, narrow trails, like sheep paths, in the hard-frozen snow. To-night a generous fire of logs gives both warmth and light inside the teepee, and the old man is calmly filling his long, red pipe for the smoke of meditation, when the voices and foot-steps of several children are distinctly heard through the stillness of the winter night.
