The undersigned indulges the hope that Mr. Vaughan will perceive in the manner in which the President, discriminating between the rights of this Government and their present exercise, has used the discretion conferred upon him an additional evidence of the desire which he sincerely entertains, and which he has heretofore caused to be communicated to Mr. Vaughan, that both Governments should, as far as practicable, abstain from all acts of authority over the territory in dispute which are not of immediate and indispensable necessity, and which would serve to create or increase excitement whilst the matter is in course of arbitration; and he feels well persuaded that Mr. Vaughan will not fail to inculcate the same spirit and to recommend in the strongest terms the observance of the same course on the part of the provincial government of New Brunswick. The undersigned offers to Mr. Vaughan the renewed assurances of his high consideration. M. VAN BUREN. _Mr. Vaughan to Mr. Van Buren_. WASHINGTON, _May 14, 1829_. Hon. MARTIN VAN BUREN, etc.: The undersigned, His Britannic Majesty's envoy extraordinary and minister plenipotentiary, has the honor to acknowledge the receipt of Mr. Van Buren's note dated the 11th instant, and he derives great satisfaction from being able to communicate to His Majesty's Government the assurances which it contains that the Government of the United States has never entertained the design of occupying Mars Hill, and that the President, in the spirit of amity, forbearance, and conciliation which he is desirous of cultivating between the two Governments, 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 to the river Madawaska. The undersigned will transmit immediately a copy of Mr. Van Buren's note to His Majesty's Government, and he forbears, therefore, from taking notice of the observations which it contains relative to the exact position of Mars Hill and to the exercise of jurisdiction in the district on the northwest of it. The undersigned begs leave to renew to Mr. Van Buren the assurances of his highest consideration. CHAS. R. VAUGHAN. _Mr. Vaughan to Mr. Van Buren_. WASHINGTON, _June 8, 1829_. Hon. MARTIN VAN BUREN, etc.:
