The British commissioners, in their report communicated by Mr. Fox, express an opinion that the true line of the treaty of 1783 is materially different from that so long contended for by Great Britain. The report is altogether ex parte in its character, and has not yet, as far as we are informed, been adopted by the British Government. It has, however, assumed a form sufficiently authentic and important to justify the belief that it is to be used hereafter by the British Government in the discussion of the question of boundary; and as it differs essentially from the line claimed by the United States, an immediate preparatory exploration and survey on our part, by commissioners appointed for that purpose, of the portions of the territory therein more particularly brought into view would, in my opinion, be proper. If Congress concur with me in this view of the subject, a provision by them to enable the Executive to carry it into effect will be necessary.

WASHINGTON, June 22, 1840.
Hon. JOHN FORSYTH, etc.:
The undersigned, Her Britannic Majesty's envoy extraordinary and minister plenipotentiary, has the honor to transmit to the Secretary of State of the United States, by order of his Government, the accompanying printed copies of a report and map which have been presented to Her Majesty's Government by Colonel Mudge and Mr. Featherstonhaugh, the commissioners employed during the last season to survey the disputed territory.
The undersigned is instructed to say that it will of course have become the duty of Her Majesty's Government to lay the said report and map before Parliament; but Her Majesty's Government have been desirous, as a mark of courtesy and consideration toward the Government of the United States, that documents bearing upon a question of so much interest and importance to the two countries should in the first instance be communicated to the President. The documents had been officially placed in the hands of Her Majesty's Government only a few days previously to the date of the instruction addressed to the undersigned.
Her Majesty's Government feel an unabated desire to bring the long-pending questions connected with the boundary between the United States and the British possessions in North America to a final and satisfactory settlement, being well aware that questions of this nature, as long as they remain open between two countries, must be the source of frequent irritation on both sides and are liable at any moment to lead to events that may endanger the existence of friendly relations.
It is obvious that the questions at issue between Great Britain and the United States must be beset with various and really existing difficulties, or else those questions would not have remained open ever since the year 1783, notwithstanding the frequent and earnest endeavors made by each Government to bring them to an adjustment; but Her Majesty's Government do not relinquish the hope that the sincere desire which is felt by both parties to arrive at an amicable settlement will at length be attended with success.
The best clew to guide the two Governments in their future proceedings may perhaps be obtained by an examination of the causes of past failure; and the most prominent amongst these causes has certainly been a want of correct information as to the topographical features and physical character of the district in dispute.
