An 1912 ethnological article describing five rare Northwest Coast and lower Columbia River baskets in the collections of the Academy of Natural Sciences of Philadelphia. It covers a Tlingit covered rattle-lid basket, a Tlingit embroidered hat, a Tlingit berrying basket, a fine grass cup, and a basket wallet with woven masks and animal figures. The author details construction (two-strand twining, false embroidery or overlay twining, wrapped twining, tee/lattice twining, selvage and border finishes), designs and their native names, and discusses tribal attribution and the raven-tail pattern. Illustrated with plates and line drawings of designs and borders.
