For small illustration see Hat 114, p. 221 in Glinsmann, Dawn. 2006. Northern Northwest Coast spruce root hats. Thesis (Ph. D.)--University of Washington, 2006. The spiral start of this hat is also illustrated as Fig. 48, p. 85 in Glinsmann. She notes on p. 85: "... the weft is laid across the spoke, wrapped around the back and twisted, brought to the working surface, and twined, resulting in a spiral effect." Glinsmann also notes on p. 54-55 that this hat appears to be a work hat, of the type Frances Paul indicates "was woven of the coarsest pieces of unpolished root and undecorated save for a coating of paint as a preservative." She notes Anthropology's hat was painted green, like other work hats of this type she examined, and comments that: "Emmons asserts that the paint assists in the water repellency of this [type of] hat, which was undoubtedly worn in the worst weather (Emmons 1993, 256.) ... De Laguna states that among the Yakutat Tlingit, "In rainy weather, a conical basketry hat ... woven of spruce roots was worn. This had a sloping brim and was tied under the chin but was not otherwise described" (de Laguna 1972, 436)."

From 19th or early 20th century exhibit label with card: "Rain-Hat (Old Pattern). - Made of grass (iris tenax), closely braided and painted green; waterproof. Shape, truncated cone. Band inside to fit head; secured by broad woolen strap which passes under chin. Sitka-Kwan Indians. Diameter, 17 1/2 ins. Height, 9 ins. Alaska, 1882. Collected by John J. McLean."

May be Sitka Tlingit?: it is identified as collected in Sitka; compare to E72431; and also see accession history re the basket part of this accession being from the "Sitka-Kwahn."
