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. The act passed at the last session for the encouragement of immigration has so far as was possible been put into operation. It seems to need amendment which will enable the officers of the Government to prevent the practice of frauds against the immigrants while on their way and on their arrival in the ports, so as to secure them here a free choice of avocations and places of settlement. A liberal disposition toward this great national policy is manifested by most of the European States, and ought to be reciprocated on our part by giving the immigrants effective national protection. I regard our immigrants as one of the principal replenishing streams which are appointed by Providence to repair the ravages of internal war and its wastes of national strength and health. All that is necessary is to secure the flow of that stream in its present fullness, and to that end the Government must in every way make it manifest that it neither needs nor designs to impose involuntary military service upon those who come from other lands to cast their lot in our country. The financial affairs of the Government have been successfully administered during the last year. The legislation of the last session of Congress has beneficially affected the revenues, although sufficient time has not yet elapsed to experience the full effect of several of the provisions of the acts of Congress imposing increased taxation. The receipts during the year from all sources, upon the basis of warrants signed by the Secretary of the Treasury, including loans and the balance in the Treasury on the 1st day of July, 1863, were $1,394,796,007.62, and the aggregate disbursements, upon the same basis, were $1,298,056,101.89, leaving a balance in the Treasury, as shown by warrants, of $96,739,905.73.
