Government to render that plan more practicable, etc., and regretted sincerely that the award of the arbiter, which conferred upon the United States three-fifths of the disputed territory, together with Rouses Point--a much greater concession than is ever likely to be obtained by a protracted negotiation--was set aside. An alleged insuperable constitutional difficulty having occasioned the rejection of the award, Sir Charles wished to ascertain previously to any further proceedings how far the General Government had the power to carry into effect any arrangement resulting from a new negotiation, the answer of Mr. McLane upon this point having been confined to stating that should a new commission of survey, freed from the restriction of following the due north line of the treaty, find anywhere westward of that line highlands separating rivers according to the treaty of 1783, a line drawn from the monument at the source of the St. Croix would be such a fulfillment of the terms of that treaty that the President could agree to make it the boundary without reference to the State of Maine. Mr. McLane, under date of 21st March, corrected the error into which Sir Charles had fallen in regard to the proceedings on the award in the Senate of the United States, and showed that that body not only failed, but by two repeated votes of 35 and 34 to 8 refused, to consent to the execution of the award, and by necessary implication denied its binding effect upon the United States, thus putting it out of the power of the President to carry it into effect and leaving the high parties to the submission situated precisely as they were prior to the selection of the arbiter.
