of the United States is only willing to admit conditionally) and the point relative to tracing the boundary along the forty-fifth degree of latitude.  This point, he observed, Mr. McLane wished to dispose of by adopting the old line of Collins and Valentine, which was suspected of great inaccuracy by both parties, and the only motive for retaining which was because some American citizens have made settlements upon territory that a new survey might throw into the possession of Great Britain.  Sir Charles denied that the acquiescence of the United States in the seven subordinate points lately submitted by His Majesty’s Government would confine the negotiation to a conventional line, to which the President had no authority to agree, and affirmed that not a step could be taken by the commissioners to be appointed according to Mr. Livingston’s proposition, notwithstanding the unlimited discretion which it was proposed to give them, unless the two Governments agreed upon two of the seven subordinate points—­“the character of the land they are to discover as dividing waters according to the treaty of 1783 and what are to be considered as Atlantic rivers.”  In answer to Mr. McLane’s observation that on many points the reasoning of the arbiter had been more favorable to the United States than to Great Britain, and that therefore acquiescence should equally apply to all the premises assumed, Sir Charles expressed his confidence that if acquiescence in them could facilitate the object which now occupied both Governments they would meet with the most favored consideration.  Sir Charles adverted to the obligations contracted under the seventh article of the convention, to the opinion of His Majesty’s Government that they were binding and its willingness to abide by the award of the arbiter.  He referred to the small majority by which he supposed the award to have been defeated in the Senate of the United States and a new negotiation advised to be opened, to the complicated nature of the plan proposed by the United States for another attempt to trace the boundary of the treaty, to the rejection of the points proposed by the British 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.
