* Expected to be completed within about one year after the amounts required to complete shall have been appropriated. These estimates are conjectural. Works have been projected for these positions. GENERAL REMARKS. In estimating for peace garrisons, it is considered disadvantageous to discipline to break up the companies when it can be avoided. Several works are reckoned as requiring peace garrisons, though they will not, at our present rate of progress, be prepared for troops for some years. Some of these garrisons might, on an emergency, be reduced for a time; but the force proposed should be regarded generally as the minimum proper to secure our ports from insult and keep watch over the military property. The garrisons, as stated, amount to forty-seven and a half companies for the Atlantic and Gulf seaboard, independent of Tampa Bay and the city of New Orleans. The works that have been under repair of class A, and those of class B, may all be regarded as completed as respects efficiency. The expenditures still required have relation, most generally, to matters of accommodation of troops, to storehouses, sea walls, wharves, and roads; to repairs of perishable portions; to the substitution of permanent for certain decaying materials; to preservation of sites from the action of the sea, &c. The amounts given in the column under the head of expended for construction or repair, include all the appropriations heretofore made. In some cases balances of these appropriations remain, and are in course of expenditure. Classes and description of works.
