Sea-lions, harbor seals, and the sea otters are the most abundant marine mammals. The men brought home the skins and prepared them by soaking them in urine and stretching them. The women undertook the sewing ("Enthnohistory:" Gross & Khera pg. 32). Preparation of the gut for clothing involved several steps. The prepared intestines were turned inside out. A bone knife was used to remove the muscle tissue and fat from the walls of the intestine. The gut was cut and stretched, and fastened to stakes to dry. It was then cut and sewn to make waterproof parkas, bags, and other receptacles (Turner, Ch. 5, pg. 70). On some hunting trips, the men would take several women with them. They would catch birds and prepare the carcasses and feathers for future use. They caught puffins, Lunda Cirrhata, Fratercula Corniculata, Guillemots, and Cephus & Murres.
