In a note dated 16th March Sir Charles R. Vaughan offered some observations upon the objections on the part of the United States to acquiesce in the points previously submitted to the American Government. He said that the adoption of the views of the British Government by the Government of the United States was meant to be the groundwork of future proceedings, whether those proceedings were to be directed to another attempt to trace the boundary as proposed by the latter or to a division of the territory depending upon the conventional line. He maintained that the arbiter had decided, as the British Government asserted, two out of the three main points submitted for his decision, viz, what ought to be considered as the northwesternmost head of the Connecticut (but which the Government 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
