The PRESIDENT OF THE SENATE:
In compliance with a resolution of the Senate passed the 1st instant, requesting "that the President inform the Senate, if not incompatible with the public interest, what negotiation has been had since the last session of Congress with Great Britain in relation to the northeastern boundary of the United States, and the progress and result thereof; also whether any arrangement, stipulation, or agreement has at any time been made between the Executive of the United States and the government of the State of Maine, or by commissioners or agents on the part of the United States and that State, having reference to any proposed transfer or relinquishment of their right of jurisdiction and territory belonging to that State, together with all documents, correspondence, and communications in relation thereto," I inform the Senate that overtures for opening a negotiation for the settlement of the boundary between the United States and the British provinces have been made to the Government of Great Britain since the last session, but that no definitive answer has yet been received to these propositions, and that a conditional arrangement has been made between commissioners appointed by me and others named by the governor of Maine, with the authority of its legislature, which can not take effect without the sanction of Congress and of the legislature aforesaid, and which will be communicated to them as soon as the contingency in which alone it was intended to operate shall happen. In the meantime it is not deemed compatible with the public interest that it should be communicated.
MARCH 2, 1833.
