British officials had continued to offer Americans partition plans for the Pacific Coast of North America throughout 1825 and 1826.

These largely originated in part from correspondence with the North West Compnany and later Hudson's Bay Company.

The border will continue to extend west on the 49th parallel to the Rocky Mountains, where the Columbia (and some times the Snake River) will be used as the border until it reaches the Pacific Ocean.

Later historians will appraise Secretary of State for Foreign Affairs George Canning as the most supportive British Foreign minister in securing a border along the Columbia.

United States Secretary of State Henry Clay had given instructions to the American plenipotentiaries to offer a partition of the Pacific Northwest along the 49th parallel to the Pacific Ocean.

The difference in the two considered plans are too much to solve, making the diplomats put off a formal colonial division once more.
