Washington Matthews' 1884 paper from the Third Annual Report of the Bureau of Ethnology describes Navajo weaving as he observed it in the early 1880s. It covers wool spinning, native and imported dyes (black, yellow, reddish, indigo, bayeta), the upright blanket loom, warp formation, heald making, and the weaving process with batten and reed-fork. It also treats diagonal and diamond twill weaving on four sheds, the weaving of belts and sashes with raised figures, and varieties of blankets. A comparison with Zuni belt weaving and an Aztec picture closes the paper. Illustrated with plates, loom and warp diagrams, and photographs of blankets.
