How far the authority given by the Legislature for procuring and establishing sites for naval purposes has been perfectly understood and pursued in the execution admits of some doubt. A statement of the expenses already incurred on that subject is now laid before you. I have in certain cases suspended or slackened these expenditures, that the Legislature might determine whether so many yards are necessary as have been contemplated. The works at this place are among those permitted to go on, and 5 of the 7 frigates directed to be laid up have been brought and laid up here, where, besides the safety of their position, they are under the eye of the Executive Administration, as well as of its agents, and where yourselves also will be guided by your own view in the legislative provisions respecting them which may from time to time be necessary. They are preserved in such condition, as well the vessels as whatever belongs to them, as to be at all times ready for sea on a short warning. Two others are yet to be laid up so soon as they shall have received the repairs requisite to put them also into sound condition. As a superintending officer will be necessary at each yard, his duties and emoluments, hitherto fixed by the Executive, will be a more proper subject for legislation. A communication will also be made of our progress in the execution of the law respecting the vessels directed to be sold. The fortifications of our harbors, more or less advanced, present considerations of great difficulty. While some of them are on a scale sufficiently proportioned to the advantages of their position, to the efficacy of their protection, and the importance of the points within it, others are so extensive, will cost so much in their first erection, so much in their maintenance, and require such a force to garrison them as to make it questionable what is best now to be done. A statement of those commenced or projected, of the expenses already incurred, and estimates of their future cost, as far as can be foreseen, shall be laid before you, that you may be enabled to judge whether any alteration is necessary in the laws respecting this subject. Agriculture, manufactures, commerce, and navigation, the four pillars of our prosperity, are then most thriving when left most free to individual enterprise. Protection from casual embarrassments, however, may sometimes be seasonably interposed. If in the course of your observations or inquiries they should appear to need any aid within the limits of our constitutional powers, your sense of their importance is a sufficient assurance they will occupy your attention. We can not, indeed, but all feel an anxious solicitude for the difficulties under which our carrying trade will soon be placed. How far it can be relieved, otherwise than by time, is a subject of important consideration.
