Under the resolution of Congress authorizing the Secretary of War to have prepared a complete system of cavalry tactics, and a system of exercise and instruction of field artillery, for the use of the militia of the United States, to be reported to Congress at the present session, a board of distinguished officers of the Army and of the militia has been convened, whose report will be submitted to you with that of the Secretary of War. The occasion was thought favorable for consulting the same board, aided by the results of a correspondence with the governors of the several States and Territories and other citizens of intelligence and experience, upon the acknowledged defective condition of our militia system, and of the improvements of which it is susceptible. The report of the board upon this subject is also submitted for your consideration. In the estimates of appropriations for the ensuing year upward of $5,000,000 will be submitted for the expenditures to be paid from the Department of War. Less than two-fifths of this will be applicable to the maintenance and support of the Army. A million and a half, in the form of pensions, goes as a scarcely adequate tribute to the services and sacrifices of a former age, and a more than equal sum invested in fortifications, or for the preparations of internal improvement, provides for the quiet, the comfort, and happier existence of the ages to come. The appropriations to indemnify those unfortunate remnants of another race unable alike to share in the enjoyments and to exist in the presence of civilization, though swelling in recent years to a magnitude burdensome to the Treasury, are generally not without their equivalents in profitable value, or serve to discharge the Union from engagements more burdensome than debt.
