The United States Secretary of State, in his note of the 5th of March, 1836, expresses a wish to know how the report of the commissioners would, according to the views of Her Majesty's Government, be likely when rendered to lead to an ultimate settlement of the question of boundary between the two Governments. In reply to this inquiry Her Majesty's Government would beg to observe that the proposal to appoint a commission originated not with them, but with the Government of the United States, and that it is therefore rather for the Government of the United States than for that of Great Britain to answer this question. Her Majesty's Government have themselves already stated that they have little expectation that such a commission could lead to any useful result, and that they would on that account be disposed to object to it; and if Her Majesty's Government were now to agree to appoint such a commission it would be only in compliance with the desire so strongly expressed by the Government of the United States, and in spite of doubts (which Her Majesty's Government still continue to entertain) of the efficacy of the measure. But with respect to the way in which the report of the commission might be likely to lead to an ultimate settlement of the question, Her Majesty's Government, in the first place, conceive that it was meant by the Government of the United States, that if the commission should discover highlands answering to the description of the treaty a connecting line drawn from these highlands to the head of the St. Croix should be deemed to be a portion of the boundary line between the two countries. But Her Majesty's Government would further beg to refer the United States Secretary of State to the notes of Mr. McLane of the 5th of June, 1833, and of the 11th and 28th of March, 1834, on this subject, in which it will be seen that the Government of the United States appears to have contemplated as one of the possible results of the proposed commission of exploration that such additional information might possibly be obtained respecting the features of the country in the district to which the treaty relates as might remove all doubt as to the impracticability of laying down a boundary in accordance with the letter of the treaty. And if the investigations of the proposed commission should show that there is no reasonable prospect of finding a line strictly conformable with the description contained in the treaty of 1783, the constitutional difficulties which now prevent the United States from agreeing to a conventional line may possibly be removed, and the way may thus be prepared for the satisfactory settlement of the difference by an equitable division of the disputed territory.
