In conclusion, it was intimated to Mr. Fox that if a negotiation be entertained by this Government at all upon the unsatisfactory basis afforded by the British counter proposition or substitute, the President will not invite it unless the authorities of the State of Maine shall think it more likely to lead to an adjustment of the question of boundary than the General Government deemed it to be, although predisposed to see it in the most favorable light.

Your excellency will perceive that in the course of these proceedings, but without abandoning the attempt to adjust the treaty line, steps necessary, from the want of power in the Federal Government, of an informal character, have been taken to test the dispositions of the respective Governments upon the subject of substituting a conventional for the treaty line.  It will also be seen from the correspondence that the British Government, despairing of a satisfactory adjustment of the line of the treaty, avows its willingness to enter upon a direct negotiation for the settlement of a conventional line if the assent of the State of Maine to that course can be obtained.

Whilst the obligations of the Federal Government to do all in its power to effect a settlement of this boundary are fully recognized on its part, it has in the event of its being unable to do so specifically by mutual consent no other means to accomplish the object amicably than by another arbitration, or a commission, with an umpire, in the nature of an arbitration.  In the contingency of all other measures failing the President will feel it to be his duty to submit another proposition to the Government of Great Britain to refer the decision of the question to a third party.  He would not, however, be satisfied in taking this final step without having first ascertained the opinion and wishes of the State of Maine upon the subject of a negotiation for the establishment of a conventional line, and he conceives the present the proper time to seek it.

I am therefore directed by the President to invite your excellency to adopt such measures as you may deem necessary to ascertain the sense of the State of Maine with respect to the expediency of attempting to establish a conventional line of boundary between that State and the British possessions by direct negotiation between the Governments of the United States and Great Britain, and whether the State of Maine will agree, and upon what conditions, if she elects to prescribe any, to abide by such settlement if the same be made.  Should the State of Maine be of opinion that additional surveys and explorations might be useful either in leading to a satisfactory adjustment of the controversy according to the terms of the treaty or in enabling the parties to decide more understandingly upon the expediency of opening a negotiation for the establishment of a line that would suit their mutual convenience and be reconcilable to their conflicting interests, and desire the creation for that purpose of a commission upon the principles and with the limited powers described in the letter of Mr. Fox, the President will without hesitation open a negotiation with Great Britain for the accomplishment of that object.
