a century has elapsed since the conclusion of the treaty in which it originated, renders it in the highest degree improbable that the two Governments can unite in believing that either the one or the other of the ranges of highlands claimed by the respective parties fulfills the required conditions of that instrument. The opinions of the parties have been over and over again expressed on this point and are well known to differ widely. The commission can neither reconcile nor change these variant opinions resting on conviction, nor will it be authorized to decide the difference. Under these impressions of the inefficiency of such a commission was the inquiry made in the letter of the undersigned of 5th March, 1836, as to the manner in which the report of the commission, as proposed to be constituted and instructed by Her Majesty's Government, was expected to lead to an ultimate settlement of the question of boundary. The results which the American proposition promised to secure were fully and frankly explained in previous notes from the Department of State, and had its advantages not been clearly understood this Government would not have devolved upon that of Her Majesty the task of illustrating them. Mr. Fox will therefore see that although the proposal to appoint a commission had its origin with this Government the modification of the American proposition was, as understood by the undersigned, so fundamentally important that it entirely changed its nature, and that the supposition, therefore, that it was rather for the Government of the United States than for that of Great Britain to answer the inquiry referred to is founded in misapprehension. Any decision made by a commission constituted in the manner proposed by the United States and instructed to seek for the highlands of the treaty of 1783 would be binding upon this Government and could without unnecessary delay be carried into effect; but if the substitute presented by Her Majesty's Government be insisted on and its principles be adopted, a resort will then be necessary to the State of Maine for her assent to all proceedings hereafter in relation to this matter, since if any arrangement can be made under it it can only be for a conventional line, to which she must of course be a party. The undersigned, in conclusion, is instructed to inform Mr. Fox that if a negotiation be entertained at all upon the inconclusive and unsatisfactory basis afforded by the British counter proposition or substitute, which possesses hardly a feature in common with the American proposition, the President will not venture to invite it unless the authorities of the State of Maine, to whom, as before stated, it will be forthwith submitted, shall think it more likely to lead to a final adjustment of the question of boundary than the General Government deems it to be, though predisposed to see it in the most favorable light.
