US Presidency
1845

Though entertaining the settled conviction that the British pretensions of title could not be maintained to any portion of the Oregon Territory upon any principle of public law recognized by nations, yet in deference to what had been done by my predecessors, and especially in consideration that propositions of compromise had been thrice made by two preceding Administrations to adjust the question on the parallel of 49 °, and in two of them yielding to Great Britain the free navigation of the Columbia, and that the pending negotiation had been commenced on the basis of compromise, I deemed it to be my duty not abruptly to break it off. In consideration, too, that under the conventions of 1818 and 1827 the citizens and subjects of the two powers held a joint occupancy of the country, I was induced to make another effort to settle this long pending controversy in the spirit of moderation which had given birth to the renewed discussion.
