It is not probable that, in any case, the boundary line between the Dominion of Canada and the United States could hare been located south of the 49th parallel, the present line. Great Britain never claimed "executive jurisdiction over any portion of that territory"—(Protocol Dec. 16 1826)—but that country did hope to maintain exclusive Jurisdiction over that part of the territory north and west of the Columbia river. This could never have been yielded by the United States. President Adams proposed that the 49th parallel, the line separating the two countries east of the Rocky Mountains, should be extended to the Pacific Ocean. That Great Britain hoped to obtain better terms is proven by the fact that the proposition was not entertained. The Joint occupation of the country, agreed to in 1818, was continued indefinitely, to be terminated by either party giving a year's notice to that effect. This treaty was continued for thirty years, but such was the feeling in this Country against Great Britain that no administration would ever have thought of consenting to any boundary line south of that finally agreed upon.
The title of the United Slates to the country west of the Rocky Mountains and north of the 42ud parallel, the then northern boundary of Mexico, was clear, and not disputed by any nation except Great Britain. Spain had discovered the coast of the Country and the United State inherited Spain's title by purchase from France. Capt. Gray, of Massachusetts, had discovered the Columbia river in 1792, and Lewis and Clark bid taken possession of it in ihe name of the United States, in 1806. The government had encouraged the settlement of Astoria in 1811, and bad assisted Rev. Jason Lee in taking out colonists to Oregon in 1839. It was believed in official circles that the colonising spirit of the American people would in the end give, as it did give, the country to the United States without a contest. As soon as the British premier was assured, though in an indirect way, by Daniel Webster, that the rejection of the proposition submitted by the younger Adams in 1826 and renewed by Tyler, by the British Commissioner, Pakenham, would involve the two countries in war, unless disavowed by the British Government, the contention of that Government that the Columbia river should be made the boundary was given up, and Tyler's proposition practically accepted, and this was the basis of the treaty settling the Oregon boundary made during Polk's Administration.
There had been some apprehension of danger to the interests the United States from the occupation of Oregon by the Hudson Bay Company, which practically held the Country. That company had such power that no other parties could purchase furs west of the mountains. Cushing reported to the
