It is possible that if it were a new and open question the maritime powers, with the lights they now enjoy, would not concede the privileges of a naval belligerent to the insurgents of the United States, destitute, as they are, and always have been, equally of ships of war and of ports and harbors. Disloyal emissaries have been neither less assiduous nor more successful during the last year than they were before that time in their efforts, under favor of that privilege, to embroil our country in foreign wars. The desire and determination of the governments of the maritime states to defeat that design are believed to be as sincere as and can not be more earnest than our own. Nevertheless, unforeseen political difficulties have arisen, especially in Brazilian and British ports and on the northern boundary of the United States, which have required, and are likely to continue to require, the practice of constant vigilance and a just and conciliatory spirit on the part of the United States, as well as of the nations concerned and their governments. Commissioners have been appointed under the treaty with Great Britain on the adjustment of the claims of the Hudsons Bay and Pugets Sound Agricultural Companies, in Oregon, and are now proceeding to the execution of the trust assigned to them. In view of the insecurity of life and property in the region adjacent to the Canadian border, by reason of recent assaults and depredations committed by inimical and desperate persons who are harbored there, it has been thought proper to give notice that after the expiration of six months, the period conditionally stipulated in the existing arrangement with Great Britain, the United States must hold themselves at liberty to increase their naval armament upon the Lakes if they shall find that proceeding necessary. The condition of the border will necessarily come into consideration in connection with the question of continuing or modifying the rights of transit from Canada through the United States, as well as the regulation of imposts, which were temporarily established by the reciprocity treaty of the 5th June, 1854. I desire, however, to be understood while making this statement that the colonial authorities of Canada are not deemed to be intentionally unjust or unfriendly toward the United States, but, on the contrary, there is every reason to expect that, with the approval of the Imperial Government, they will take the necessary measures to prevent new incursions across the border.
