Originally identified as eskimo in origin, the embroidery in caribou hair on a pair of children's boots was considered characteristic of the Aleutian islands. The decoration is described in detail. Fur-bearing animals indigenous to Alaska and Aleutians were listed and samples of their hair examined microscopically. Comparison with known samples, photomicrographs of known hairs, and actual pelts from the collection allowed positive identification of seal, caribou, and polar bear hair and possibly also ermine. The presence of haematite and red ochre was confirmed, with possibly also gunpowder. Chemical analysis suggested that pesticides applied after acquisition by the museum might have contaminated the boots. Damage caused by poor mounting was repaired once the boots had been humidified sufficiently to remove distortion. Details are given of techniques used and materials employed.
