The undersigned can not acquiesce in the supposition that, because the agent of His Britannic Majesty thought proper in the proceedings before the commissioners to lay claim to all that portion of the State of Maine which lies north of a line running westerly from Mars Hill, and designated as the limit or boundary of the British claim, thereby the United States or the State of Maine ceased to have jurisdiction in the territory thus claimed. In the view of this Government His Britannic Majesty's agent might with equal justice have extended his claim to any other undisputed part of the State as to claim the portion of it which he has drawn in question, and in such case the lieutenant-governor of New Brunswick could surely not have considered a continuance on the part of the United States and of the State of Maine to exercise their accustomed jurisdiction and authority to be an encroachment. If so, in what light are we to regard the continued acts of jurisdiction now exercised by him in the Madawaska settlement? More than twenty years ago large tracts of land lying westward of Mars Hill, and northward on the river Restook, were granted by the State of Massachusetts, which tracts are held and possessed under those grants to this day, and the United States and the States of Massachusetts and Maine, in succession, have never ceased to exercise that jurisdiction which the unsettled condition of the country in that region and other circumstances admitted and required. The undersigned, therefore, can not discover in the facts and circumstances of the case any just principles upon which Sir Howard Douglas could predicate his protest. He has, however, submitted the note which he had the honor to receive from Mr. Vaughan to the President of the United States, and is by him directed to say in reply that although this Government could feel no difficulty in the exercise of what it deems an unquestionable right, and could not allow itself to be restrained by the protest of the lieutenant-governor of New Brunswick, yet, as a further proof of the spirit of amity, forbearance, and conciliation which the President is desirous of cultivating between the two Governments, he has decided to postpone for the present the exercise of the authority vested in him by the Congress of the United States to cause to be surveyed and laid out a military road to be continued from Mars Hill, or such other point on the military road laid out in the State of Maine as he may think proper, to the mouth of the river Madawaska, and to add that the lieutenant-governor of New Brunswick is under a misapprehension as to the design of this Government to occupy Mars Hill as a military station, no such intention being entertained by the President, nor have any measures been taken by this Government with an ulterior view to that object.
