The twelve specimens here analysed were obtained from the island of Kagamil in the Four Mountain Group and from the island of Shiprock in Umnak Pass. No date other than merely "pre-Russian" has been assigned either burial cave from whence the specimens were obtained, although it is likely that Dr. Aleš Hrdlička will formulate a satisfactory chronology for the known sites of the Aleutian Islands. The specimens consist of the fragments of five baskets or mats, five cords, and two bird skins, the latter presumably from parkas. While these specimens are few in number and in no wise unique, the paucity of published material on the prehistoric textiles of the Aleutian Islands justifies this paper.
