From the book:
The Kwakiutl language is spoken in three dialects . the Kwakiutl proper, the Heiltsuk* and the Gyit'ama't. The first is spoken by the tribes of Vancouver Island and of the coast southeast of Rivers Inlet; the second by the tribes inhabiting the coast between Rivers Inlet and Gardner Channel; the last in Gardner and Douglas Channels. It will be found that phonetics and vocabulary of the northern and southern tribes are much alike, while the middle dialect stands more apart. This is probably due to the admixture of Bilqula elements in the central region. The vocabularies contained in the following pages were collected by the author in 1886, 1888, 1889, 1890. As slight differences are found between the vocabularies of the various tribes, the tribe from which the words were collected are given. The following abbreviations have been used: L. for Le'kwiltok', N.—Nimkish, K.—Kwakiutl, Tl.—Tlatlasik-oala, A.—Awi'ky'enoq. H.—He'iltsuk-, G.—Gyit'ama't, Kwakiutl Dialect. Heiltsuk* Dialect. Gyit'ama't Dialect.
