A short note in Science summarizing a paper by Judge J. G. Henderson on the textile fabrics of the ancient inhabitants of the Mississippi Valley. It describes similarities between the spinning and weaving tools and processes of modern Indians and these ancient peoples, and lists the materials used: tree bark, nettle, and the hair of bear, buffalo, deer and dog. It outlines the development from rolling fiber on the thigh to spindles and looms, and notes the paper was illustrated with drawings, raw materials and models.
