Annotation: This treaty brought an end to the Oregon boundary dispute by settling competing American and British claims to the Oregon Country, which had been jointly occupied by both Britain and the U.S. since the Treaty of 1818.
Document: ART. I. From the point of the forty-ninth parallel of north latitude, where the boundary laid down in existing treaties and conventions between the United States and Great Britain terminates, the line of boundary between the territories of the United States and those of her Britannic Majesty shall be continued westward along the said forty-ninth parallel of north latitude to the middle of the channel which separates the continent from Vancouver's Island, and thence southerly through the middle of the said channel, and of Fuca's Straits, to the Pacific Ocean: Provided, however, That the navigation of the whole of the said channel and straits, south of the forty-ninth parallel of north latitude, remain free and open to both parties.
ART. II. From the point at which the forty-ninth parallel of north latitude shall be found to intersect the great northern branch of the Columbia River, the navigation of the said branch shall be free and open to the Hudson's Bay Company, and to all British subjects trading with the same, to the point where the said branch meets the main stream of the Columbia, and thence down the said main stream to the ocean, with free access into and through the said river or rivers, it being understood that all the usual portages along the line thus described shall, in like manner, be free and open. In navigating the said river or rivers, British subjects, with their goods and produce, shall be treated on the same footing as citizens of the United States; it being, however, always understood that nothing in this article shall be construed as preventing, or intended to prevent, the government of the United States from making any regulations respecting the navigation of the said river or rivers not inconsistent with the present treaty.
ART. III. In the future appropriation of the territory south of the forty-ninth parallel of north latitude, as provided in the first article of this treaty, the possessory rights of the Hudson's Bay Company, and of all British subjects who may be already in the occupation of land or other property lawfully acquired within the said territory, shall be respected.
ART. IV. The farms, lands, and other property of every description, belonging to the Puget's Sound Agricultural Company, on the north side of the Columbia River, shall be confirmed to the said company. In case, however, the situation of those farms and lands should be considered by the United States to be of public and political importance, and the United States government should signify a desire to obtain possession of the whole, or of any part thereof, the property so required shall be transferred to the said government, at a proper valuation, to be agreed upon between the parties. . .
