The ratifications of the naturalization convention between Great Britain and the United States have also been exchanged during the recess, and thus a long-standing dispute between the two Governments has been settled in accordance with the principles always contended for by the United States. In April last, while engaged in locating a military reservation near Pembina, a corps of engineers discovered that the commonly received boundary line between the United States and the British possessions at that place is about 4,700 feet south of the true position of the forty-ninth parallel, and that the line, when run on what is now supposed to be the true position of that parallel, would leave the fort of the Hudsons Bay Company at Pembina within the territory of the United States. This information being communicated to the British Government, I was requested to consent, and did consent, that the British occupation of the fort of the Hudsons Bay Company should continue for the present. I deem it important, however, that this part of the boundary line should be definitely fixed by a joint commission of the two Governments, and I submit herewith estimates of the expense of such a commission on the part of the United States and recommend that an appropriation be made for that purpose. The land boundary has already been fixed and marked from the summit of the Rocky Mountains to the Georgian Bay. It should now be in like manner marked from the Lake of the Woods to the summit of the Rocky Mountains. I regret to say that no conclusion has been reached for the adjustment of the claims against Great Britain growing out of the course adopted by that Government during the rebellion. The cabinet of London, so far as its views have been expressed, does not appear to be willing to concede that Her Majesty's Government was guilty of any negligence, or did or permitted any act during the war by which the United States has just cause of complaint. Our firm and unalterable convictions are directly the reverse. I therefore recommend to Congress to authorize the appointment of a commission to take proof of the amount and the ownership of these several claims, on notice to the representative of Her Majesty at Washington, and that authority be given for the settlement of these claims by the United States, so that the Government shall have the ownership of the private claims, as well as the responsible control of all the demands against Great Britain. It can not be necessary to add that whenever Her Majesty's Government shall entertain a desire for a full and friendly adjustment of these claims the United States will enter upon their consideration with an earnest desire for a conclusion consistent with the honor and dignity of both nations.
