You are referred to the report of the Secretary of the Navy for a satisfactory view of the operations of the Department under his charge during the present year. In the construction of vessels at the different navy yards and in the employment of our ships and squadrons at sea that branch of the service has been actively and usefully employed. While the situation of our commercial interests in the West Indies required a greater number than usual of armed vessels to be kept on that station, it is gratifying to perceive that the protection due to our commerce in other quarters of the world has not proved insufficient. Every effort has been made to facilitate the equipment of the exploring expedition authorized by the act of the last session, but all the preparation necessary to enable it to sail has not yet been completed. No means will be spared by the Government to fit out the expedition on a scale corresponding with the liberal appropriations for the purpose and with the elevated character of the objects which are to be effected by it. I beg leave to renew the recommendation made in my last annual message respecting the enlistment of boys in our naval service, and to urge upon your attention the necessity of further appropriations to increase the number of ships afloat and to enlarge generally the capacity and force of the Navy. The increase of our commerce and our position in regard to the other powers of the world will always make it our policy and interest to cherish the great naval resources of our country. The report of the Post Master General presents a gratifying picture of the condition of the Post Office Department. Its revenues for the year ending the 30th June last were $3,398,455.19, showing an increase of revenue over that of the preceding year of $404,878.53, or more than 13%. The expenditures for the same year were $2,755,623.76, exhibiting a surplus of $642,831.43. The Department has been redeemed from embarrassment and debt, has accumulated a surplus exceeding half a million dollars, has largely extended and is preparing still further to extend the mail service, and recommends a reduction of postages equal to about 20%. It is practicing upon the great principle which should control every branch of our Government of rendering to the public the greatest good possible with the least possible taxation to the people. The scale of postages suggested by the Post Master General recommends itself, not only by the reduction it proposes, but by the simplicity of its arrangement, its conformity with the Federal currency, and the improvement it will introduce into the accounts of the Department and its agents.
