is difficult to understand upon what grounds any expectation could have been formed that such a proposal could be entertained by the British Government, for such an arrangement would give to the United States even greater advantages than they would obtain by an unconditional acquiescence in their claim to the whole of the disputed territory, because such an arrangement would, in the first place, give to Maine all that part of the disputed territory which lies to the south of the St. John, and would, in the next place, in exchange for the remaining part of the disputed territory which lies to the north of the St. John, add to the State of Maine a large district of New Brunswick lying between the United States boundary and the southern part of the course of the St. John—­a district smaller, indeed, in extent, but much more considerable in value, than the portion of the disputed territory which lies to the north of the St. John.

But with respect to a conventional line generally, the Government of Washington has stated that it has not at present the powers constitutionally requisite for treating for such a line and has no hopes of obtaining such powers until the impossibility of establishing the line described by the treaty shall have been completely demonstrated by the failure of another attempt to trace that line by a local survey.

Under these circumstances it appears that a conventional line can not at present be agreed upon, and that such a mode of settlement is in the existing state of the negotiation impossible.

Thus, then, the award of the King of the Netherlands has been abandoned by both parties in consequence of its rejection by the American Senate, and a negotiation between the two Governments for a conventional line suited to the interests and convenience of the two parties has for the present been rendered impossible by difficulties arising on the part of the United States; and both Governments are alike averse to a new arbitration.  In this state of things the Government of the United States has proposed to the British cabinet that another attempt should be made to trace out a boundary according to the letter of the treaty, and that a commission of exploration and survey should be appointed for that purpose.

Her Majesty’s Government have little expectation that such a commission could lead to any useful result, and on that account would be disposed to object to the measure; but at the same time they are so unwilling to reject the only plan now left which seems to afford a chance of making any further advance in this long-pending matter that they will not withhold their consent to such a commission if the principle upon which it is to be formed and the manner in which it is to proceed can be satisfactorily settled.

The United States Government have proposed two modes in which such a commission might be constituted:  First, that it might consist of commissioners named in equal numbers by each of the two Governments, with an umpire to be selected by some friendly European power; secondly, that it might be entirely composed of scientific Europeans, to be selected by a friendly sovereign, and might be accompanied in its operations by agents of the two different parties, in order that such agents might give to the commissioners assistance and information.
