This file contains letters and texts written by Joyce Wilke to Wilson Duff. The letters largely discuss the topic of publication, including revision notes and comments on errors made in other authors' texts. Texts included in the file focus on Coast Salish dancing and dance traditions, as well as economic relationships between Indigenous Nations of the Northwest Coast and European traders.
Texts on the theme of Coast Salish dances include Wilkes' typed summary of a Winter Dance that took place in Esquimalt in 1943, and handwritten notes about Spirit Dances at the Swinomish Reservation in 1940-41. The latter also includes language notes about community terms relevant to these dances. There is also a published article by David F. Aberle that theorizes about a so-called Prophet Dance movement.
Wilkes' more extensive manuscript represents her doctoral dissertation concerning maritime trade between various coastal First Nations and European traders, which focuses on the European demand for sea otter fur, and the interest of First Nations in obtaining iron, copper, firearms, and textiles. The author also discusses food and liquor as part of trade relations. A photocopy and original version of Wilkes' bibliography are also included.
