George Gibbs, Dictionary of the Chinook Jargon…
“ With the exception of Franchere, whose short vocabulary was published by Mr. Gallatin, and Mr. Hale, all the writers mentioned by Ludwig who have given specimens of the Chinook language, have presented it in its Jargon form, more or less mixed with the neighboring ones, and with corruptions of French and English words. Mr. Swan, among others, has been led into this error. The place of his residence, Shoalwater Bay, is common ground of the Chinook and Chihalis Indians, and the degraded remnants of the two tribes are closely intermarried, and use both languages almost indifferently. ”
