The Military Academy continues to answer all the purposes of its establishment, and not only furnishes well-educated officers to the Army, but serves to diffuse throughout the mass of our citizens individuals possessed of military knowledge and the scientific attainments of civil and military engineering. At present the cadet is bound, with consent of his parents or guardians, to remain in service five years from the period of his enlistment, unless sooner discharged, thus exacting only one year's service in the Army after his education is completed. This does not appear to me sufficient. Government ought to command for a longer period the services of those who are educated at the public expense, and I recommend that the time of enlistment be extended to seven years, and the terms of the engagement strictly enforced. The creation of a national foundry for cannon, to be common to the service of the Army and Navy of the United States, has been heretofore recommended, and appears to be required in order to place our ordnance on an equal footing with that of other countries and to enable that branch of the service to control the prices of those articles and graduate the supplies to the wants of the Government, as well as to regulate their quality and insure their uniformity. The same reasons induce me to recommend the erection of a manufactory of gunpowder, to be under the direction of the Ordnance Office. The establishment of a manufactory of small arms west of the Alleghany Mountains, upon the plan proposed by the Secretary of War, will contribute to extend throughout that country the improvements which exist in establishments of a similar description in the Atlantic States, and tend to a much more economical distribution of the armament required in the western portion of our Union. The system of removing the Indians west of the Mississippi, commenced by Mr. Jefferson in 1804, has been steadily persevered in by every succeeding President, and may be considered the settled policy of the country. Unconnected at first with any well-defined system for their improvement, the inducements held out to the Indians were confined to the greater abundance of game to be found in the West; but when the beneficial effects of their removal were made apparent a more philanthropic and enlightened policy was adopted in purchasing their lands east of the Mississippi. Liberal prices were given and provisions inserted in all the treaties with them for the application of the funds they received in exchange to such purposes as were best calculated to promote their present welfare and advance their future civilization. These measures have been attended thus far with the happiest results.
