I herewith transmit to the Senate of the United States a report from the Secretary of State, accompanied by a copy of the correspondence requested by their resolution of the 5th ultimo. M. VAN BUREN. DEPARTMENT OF STATE, _Washington, March 7, 1838_. The PRESIDENT OF THE UNITED STATES: The Secretary of State, to whom has been referred the resolution of the Senate of the 5th of February, requesting the President of the United States to communicate to that body, in such manner as he shall deem proper, all the correspondence recently received and had between this and the Governments of Great Britain and the State of Maine on the subject of the northeastern boundary, has the honor to report to the President the accompanying copy of letters, which comprise all the correspondence in the Department asked for by the resolution. Respectfully submitted, JOHN FORSYTH. _Mr. Fox to Mr. Forsyth_. WASHINGTON, _January 10, 1838_. Hon. JOHN FORSYTH, etc.: The undersigned, Her Britannic Majesty's envoy extraordinary and minister plenipotentiary, is directed by his Government to make the following observations to Mr. Forsyth, Secretary of State of the United States, with reference to certain points connected with the question of the northeastern boundary, which question forms the subject of the accompanying note, which the undersigned has the honor this day to address to Mr. Forsyth: The British Government, with a view to prevail upon that of the United States to come to an understanding with Great Britain upon the river question, had stated that the King of the Netherlands in his award had decided that question according to the British interpretation of it and had expressed his opinion that the rivers which fall into the Bay of Fundy are not to be considered as Atlantic rivers for the purposes of the treaty. Mr. Forsyth, however, in his note to Sir Charles Vaughan of the 28th of April, 1835, controverts this assertion and maintains that the King of the Netherlands did not in his award express such an opinion, and Mr. Forsyth quotes a passage from the award in support of this proposition.
