I beg leave particularly to call your attention to the accompanying report from the Secretary of War. Besides the present state of the war which has so long afflicted the Territory of Florida, and the various other matters of interest therein referred to, you will learn from it that the Secretary has instituted an inquiry into abuses, which promises to develop gross enormities in connection with Indian treaties which have been negotiated, as well as in the expenditures for the removal and subsistence of the Indians. He represents also other irregularities of a serious nature that have grown up in the practice of the Indian Department, which will require the appropriation of upward of $200,000 to correct, and which claim the immediate attention of Congress. In reflecting on the proper means of defending the country we can not shut our eyes to the consequences which the introduction and use of the power of steam upon the ocean are likely to produce in wars between maritime states. We can not yet see the extent to which this power may be applied in belligerent operations, connecting itself as it does with recent improvements in the science of gunnery and projectiles; but we need have no fear of being left, in regard to these things, behind the most active and skillful of other nations if the genius and enterprise of our fellow-citizens receive proper encouragement and direction from Government. True wisdom would nevertheless seem to dictate the necessity of placing in perfect condition those fortifications which are designed for the protection of our principal cities and roadsteads. For the defense of our extended maritime coast our chief reliance should be placed on our Navy, aided by those inventions which are destined to recommend themselves to public adoption, but no time should be lost in placing our principal cities on the seaboard and the Lakes in a state of entire security from foreign assault. Separated as we are from the countries of the Old World, and in much unaffected by their policy, we are happily relieved from the necessity of maintaining large standing armies in times of peace. The policy which was adopted by Mr. Monroe shortly after the conclusion of the late war with Great Britain of preserving a regularly organized staff sufficient for the command of a large military force should a necessity for one arise is founded as well in economy as in true wisdom. Provision is thus made, upon filling up the rank and file, which can readily be done on any emergency, for the introduction of a system of discipline both promptly and efficiently. All that is required in time of peace is to maintain a sufficient number of men to guard our fortifications, to meet any sudden contingency, and to encounter the first shock of war. Our chief reliance must be placed on the militia; they constitute the great body of national guards, and, inspired by an ardent love of country, will be found ready at all times
