Notwithstanding the security for future repose which the United States ought to find in their love of peace and their constant respect for the rights of other nations, the character of the times particularly inculcates the lesson that, whether to prevent or repel danger, we ought not to be unprepared for it. This consideration will sufficiently recommend to Congress a liberal provision for the immediate extension and gradual completion of the works of defense, both fixed and floating, on our maritime frontier, and an adequate provision for guarding our inland frontier against dangers to which certain portions of it may continue to be exposed. As an improvement in our military establishment, it will deserve the consideration of Congress whether a corps of invalids might not be so organized and employed as at once to aid in the support of meritorious individuals excluded by age or infirmities from the existing establishment, and to procure to the public the benefit of their stationary services and of their exemplary discipline. I recommend also an enlargement of the Military Academy already established, and the establishment of others in other sections of the Union; and I can not press too much on the attention of Congress such a classification and organization of the militia as will most effectually render it the safeguard of a free state. If experience has shewn in the recent splendid achievements of militia the value of this resource for the public defense, it has shewn also the importance of that skill in the use of arms and that familiarity with the essential rules of discipline which can not be expected from the regulations now in force. With this subject is intimately connected the necessity of accommodating the laws in every respect to the great object of enabling the political authority of the Union to employ promptly and effectually the physical power of the Union in the cases designated by the Constitution. The signal services which have been rendered by our Navy and the capacities it has developed for successful cooperation in the national defense will give to that portion of the public force its full value in the eyes of Congress, at an epoch which calls for the constant vigilance of all governments. To preserve the ships now in a sound state, to complete those already contemplated, to provide amply the imperishable materials for prompt augmentations, and to improve the existing arrangements into more advantageous establishments for the construction, the repairs, and the security of vessels of war is dictated by the soundest policy.
