the plains the boat was virtually unknown, except for the tub-shaped skin boat of the Mandan and associated tribes of the upper Missouri. p> The Eskimo were noted for their artistic carvings of bones and walrus ivory; the Pueblo for their turquoise-inlaid work and their wood carving, especially mythologic figurines, and the Atlantic and California coast tribes for their work in shell. The wampum, or shell beads, made chiefly from the shells of various clams found along the Atlantic coast have become historic, having been extensively used not only for dress ornamentation, but also on treaty belts, as tribal tribute, and as a standard of value answering the purpose of money. The ordinary stone hammer or club, found in nearly every tribe, represented much patient labour, while the whole skill of the artist was frequently expended upon the stone-carved pipe. The black stone pipes of the Cherokee were famous in the southern states, and the red stone pipe of catlinite from a single quarry in Minnesota was reputed sacred and was smoked at the ratification of all solemn tribal engagements throughout the plains and the lake-region. Knives, lance-blades, and arrow-heads were also usually of stone, preferably flint or obsidian. Along the Gulf Coast, keen-edged knives fashioned from split canes were in use. Corn mortars and bowls were usually of wood in the timber region and of stone in the arid country. Hide-scrapers were of bone, and spoons of wood or horn. Metal-work was limited chiefly to the fashioning of gorgets and other ornaments hammered out from native copper, found in the southern Alleghenies, about Lake Superior, and about Copper River in Alaska. The art of smelting was apparently unknown. Under Franciscan and later Mexican teaching the Navahos have developed a silver-working art which compares in importance with their celebrated basket-weaving, the material used being silver coins melted down in stone molds of their own carving. Mica was mined in the Carolina mountains by the local tribes and fashioned into gorgets and mirrors, which found their way by trade as far as the western prairies, All of these arts belonged to the men. p> Basket-weaving in wood splits, cane, rushes, yucca-or bark-fibre, and various grasses was practiced by the same tribes which made pottery, and excepting in a few tribes, was likewise a women's work. The basket was stained in various designs with vegetable dyes. The Cherokee made a double-walled basket. Those of the Choctaw, Pueblo tribes, Jicarillo, and Piute were noted for beauty of design and execution, but the Pomo and other tribes of California excelled in all closeness and delicacy of weaving and richness of decoration, many of their grass baskets being water-tight and almost hidden under an inter-weaving of bright-coloured plumage, and further decorated around the top with pendants of shining mother-of-pearl. The weaving of grass or rush mats for covering beds or wigwams may be considered as ...
