After our transition from the state of colonies to that of an independent nation many points were found necessary to be settled between us and Great Britain. Among them was the demarcation of boundaries not described with sufficient precision in the treaty of peace. Some of the lines that divide the States and Territories of the United States from the British Provinces have been definitively fixed. That, however, which separates us from the Provinces of Canada and New Brunswick to the north and the east was still in dispute when I came into office, but I found arrangements made for its settlement over which I had no control. The commissioners who had been appointed under the provisions of the treaty of Ghent having been unable to agree, a convention was made with Great Britain by my immediate predecessor in office, with the advice and consent of the Senate, by which it was agreed "that the points of difference which have arisen in the settlement of the boundary line between the American and British dominions, as described in the fifth article of the treaty of Ghent, shall be referred, as therein provided, to some friendly sovereign or State, who shall be invited to investigate and make a decision upon such points of difference;" and the King of the Netherlands having by the late President and His Britannic Majesty been designated as such friendly sovereign, it became my duty to carry with good faith the agreement so made into full effect. To this end I caused all the measures to be taken which were necessary to a full exposition of our case to the sovereign arbiter, and nominated as minister plenipotentiary to his Court a distinguished citizen of the State most interested in the question, and who had been one of the agents previously employed for settling the controversy. On the 10th day of January last His Majesty the King of the Netherlands delivered to the plenipotentiaries of the United States and of Great Britain his written opinion on the case referred to him. The papers in relation to the subject will be communicated by a special message to the proper branch of the Government with the perfect confidence that its wisdom will adopt such measures as will secure an amicable settlement of the controversy without infringing any constitutional right of the States immediately interested. It affords me satisfaction to inform you that suggestions made by my direction to the chargé d'affaires of His Britannic Majesty to this Government have had their desired effect in producing the release of certain American citizens who were imprisoned for setting up the authority of the State of Maine at a place in the disputed territory under the actual jurisdiction of His Britannic Majesty. From this and the assurances I have received of the desire of the local authorities to avoid any cause of collision I have the best hopes that a good understanding will be kept up until it is confirmed by the final disposition of the subject.
