With regard to the rule of practical surveying offered as the basis of the American proposition, he said if it should become material to do so—­which was not to be anticipated—­he would find no difficulty either in fortifying the ground occupied by this Government in this regard or in satisfying Sir Charles that the instance brought into notice by His Britannic Majesty’s Government of a supposed departure from the rule was not at variance with the assertion of Mr. Livingston repeated by Mr. McLane.  The Secretary therefore limited himself to the remark that the line of demarcation referred to by Sir Charles was not established as the true boundary prescribed by the treaty of 1783, but was a conventional substitute for it, the result of a new negotiation controlled by other considerations than those to be drawn from that instrument only.

The Secretary expressed the President’s unfeigned regret upon learning the decision of His Majesty’s Government not to agree to the proposition made on the part of the United States without a precedent compliance by them with inadmissible conditions.  He said that the views of this Government in regard to this proposal of His Majesty’s Government had been already communicated to Sir Charles R. Vaughan, and the President perceived with pain that the reasons upon which these opinions were founded had not been found to possess sufficient force and justice to induce the entire withdrawal of the objectionable conditions, but that, on the contrary, while His Majesty’s Government had been pleased to waive for the present six of the seven opinions referred to, the remaining one, amongst the most important of them all, was still insisted upon, viz, that the St. John and Restigouche should be treated by the supposed commission as not being Atlantic rivers according to the meaning of those terms in the treaty.  With reference to that part of Sir Charles’s communication which seeks to strengthen the ground heretofore taken on this point by the British Government by calling to its aid the supposed confirmation of the arbiter, the Secretary felt himself warranted in questioning whether the arbiter had ever given his opinion that the rivers St. John and Restigouche can not be considered according to the meaning of the treaty as rivers falling into the Atlantic, and he insisted that it was not the intention of the arbiter to express the opinion imputed to him.

The Secretary also informed Sir Charles that the President could not consent to clog the submission with the condition proposed by Her Majesty’s Government; that a just regard to the rights of the parties and a proper consideration of his own duties required that the new submission, if made, should be made without restriction or qualification upon the discretion of the commissioners other than such as resulted from established facts and the just interpretation of the definitive treaty, and such as had been heretofore and were now again tendered to His Britannic Majesty’s
