The undersigned, His Britannic Majesty's envoy extraordinary and minister plenipotentiary, has the honor to acknowledge the receipt of the note of the Secretary of State of the United States, in answer to the representation which he was called upon to make respecting proceedings of the States of Massachusetts and Maine in the disputed territory. To understand correctly the bearings of the roads which those States have resolved to construct requires a more accurate knowledge of the topography of the country through which they are to pass than the undersigned possesses, but he will not fail to transmit a copy of Mr. McLane's note, together with its inclosures, to His Majesty's lieutenant-governor of New Brunswick. In the meantime the undersigned begs leave to observe that the letter from the executive of Maine states that one of the roads surveyed and located lies, for the greater part of it, within the undisputed limits of that State, although it is contemplated to extend it to the Aroostook River. The land agent of Massachusetts is aware that the road from the river Matawamkeag to the Aroostook is the one that has given rise to complaint, and which, he observes, "is now nearly completed." As the Aroostook River, from its source till it falls into the St. John, flows exclusively through the disputed territory, to reach it by a road from the State of Maine must cause an encroachment and be considered an attempt to assume a right of possession in territory which has never yet been set apart from the original possession of Great Britain, on account of the difficulties of ascertaining the boundary according to the treaty of 1783. With regard to the cutting down and sale of timber, the justification of the land agent at Boston will be submitted to Sir Archibald Campbell, and the undersigned is sure that the grievance complained of (taking away timber which had been seized by the agent from Massachusetts) will be attended to. The undersigned receives with great satisfaction the assurances of Mr. McLane that "a conciliatory and forbearing disposition prevails on the part of Massachusetts and Maine, and that no measure will be taken or any acts authorized by them which may justly be considered as a violation of the understanding in regard to the disputed territory;" and he can not conclude without begging leave to acknowledge the readiness with which the President directed inquiries to be made and the desire which he has shewn on this and every similar occasion to prevent any encroachment on the disputed territory pending the settlement of the boundary now in progress between the two Governments. The undersigned has the honor to assure Mr. McLane of his most distinguished consideration. CHAS. R. VAUGHAN. _Sir Charles R. Vaughan to Mr. McLane_. WASHINGTON, _February 28, 1834_. Hon. LOUIS McLANE, etc.:
