The treaty negotiations were conducted in
Chinook Jargon, which, according to Paul Prucha, was "a
lingua franca along the Pacific Northwest coast but hardly an effective tool for sensitive negotiations, for it had a vocabulary of only about 500 words, and a single word might be used to translate a number of different English words." The final treaty contained 13 articles. The first described the land being ceded to the United States, which was defined as bounded by the Pacific Ocean to the west, the southern boundary of the recent
Makah cession to the north, which ran east to "the middle of the coast range of mountains" (meaning the
Olympic Mountains). The eastern cession boundary ran south "with said range" (the Olympics) to the ridge dividing the
drainage basins of the
Chehalis River and the
Quinault River. From there the line ran west along the watershed ridge to the Pacific Ocean. This somewhat vague definition was further confused by the way the Makah cession boundary had been defined as extending south to the lands occupied by the Quileute. This
circular definition, along with the unclear phrases about where the line ran through the Olympics, resulted in confusion and legal problems which continue to the present day. The second article of the treaty described how the reservation would be established and that the tribes would be required to move there. Article three promised the tribes the right of fishing "in all usual and accustomed grounds and stations is secured to said Indians in common with all citizens of the Territory". Hunting, gathering, and the pasturing of horses were also protected with certain provision. In article four the United States promised to pay $25,000 for the land cession, to be paid over a number of years. Article five provides an additional $2,500 to enable tribes to remove and settle upon the reservation. Article six described how the president could any future time and "as he deems fit" make a new reservation elsewhere and requires the tribes to move there, or require the tribes to be consolidated with other tribes on another reservation, with all federal annuities also consolidated. The president could also cause the reservation to be subdivided into lots and assigned to individuals and families. Articles seven and nine dealt with the prohibition of alcohol and debts. Article eight required the tribes to "acknowledge their dependence on the United States", and briefly outlined how crimes would be dealt with. In article ten the United States promised to establish and support for 20 years an agricultural and industrial school, free to the children of the tribes and located at the territorial central Puget Sound agency. A physician was also to be provided, also at the central agency. Article eleven required the tribes to free any slaves they held. Article thirteen forbid the tribes from trading "at Vancouver's Island or elsewhere outside the dominion of the United States", nor to allow "foreign Indians" to live in the reservation. The last article said that the terms of the treaty would take effect upon ratification by the President and the Senate. ==After the treaty==
