After a patient investigation of the case and of the statements of each party, His Majesty the Emperor, on the 21st day of October last, signed his award in writing, decreeing that the claim of the Government of the United States, that the boundary line between the territories of Her Britannic Majesty and the United States should be drawn through the Haro Channel, is most in accordance with the true interpretation of the treaty concluded on the 15th of June, 1846, between the Governments of Her Britannic Majesty and of the United States.

Copies of the “case” presented on behalf of each Government, and of the “statement in reply” of each, and a translation of the award, are transmitted herewith.

This award confirms the United States in their claim to the important archipelago of islands lying between the continent and Vancouvers Island, which for more than twenty-six years (ever since the ratification of the treaty) Great Britain has contested, and leaves us, for the first time in the history of the United States as a nation, without a question of disputed boundary between our territory and the possessions of Great Britain on this continent.

It is my grateful duty to acknowledge the prompt, spontaneous action of Her Majesty’s Government in giving effect to the award.  In anticipation of any request from this Government, and before the reception in the United States of the award signed by the Emperor, Her Majesty had given instructions for the removal of her troops which had been stationed there and for the cessation of all exercise or claim of jurisdiction, so as to leave the United States in the exclusive possession of the lately disputed territory.  I am gratified to be able to announce that the orders for the removal of the troops have been executed, and that the military joint occupation of San Juan has ceased.  The islands are now in the exclusive possession of the United States.

It now becomes necessary to complete the survey and determination of that portion of the boundary line (through the Haro Channel) upon which the commission which determined the remaining part of the line were unable to agree.  I recommend the appointment of a commission to act jointly with one which may be named by Her Majesty for that purpose.

Experience of the difficulties attending the determination of our admitted line of boundary, after the occupation of the territory and its settlement by those owing allegiance to the respective Governments, points to the importance of establishing, by natural objects or other monuments, the actual line between the territory acquired by purchase from Russia and the adjoining possessions of Her Britannic Majesty.  The region is now so sparsely occupied that no conflicting interests of individuals or of jurisdiction are likely to interfere to the delay or embarrassment of the actual location of the line.  If deferred until population shall enter and occupy the territory, some trivial contest of neighbors may again array the two Governments in antagonism.  I therefore recommend the appointment of a commission, to act jointly with one that may be appointed on the part of Great Britain, to determine the line between our Territory of Alaska and the conterminous possessions of Great Britain.
