Third. Twenty-seven cruising ships, three of which are built of iron, of small tonnage, and twenty-four of wood. Of these wooden vessels it is estimated by the Chief Constructor of the Navy that only three will be serviceable beyond a period of six years, at which time it may be said that of the present naval force nothing worthy the name will remain. All the vessels heretofore authorized are under contract or in course of construction except the armored ships, the torpedo and dynamite boats, and one cruiser. As to the last of these, the bids were in excess of the limit fixed by Congress. The production in the United States of armor and gun steel is a question which it seems necessary to settle at an early day if the armored war vessels are to be completed with those materials of home manufacture. This has been the subject of investigation by two boards and by two special committees of Congress within the last three years. The report of the Gun Foundry Board in 1884, of the Board on Fortifications made in January last, and the reports of the select committees of the two Houses made at the last session of Congress have entirely exhausted the subject, so far as preliminary investigation is involved, and in their recommendations they are substantially agreed. In the event that the present invitation of the Department for bids to furnish such of this material as is now authorized shall fail to induce domestic manufacturers to undertake the large expenditures required to prepare for this new manufacture, and no other steps are taken by Congress at its coming session, the Secretary contemplates with dissatisfaction the necessity of obtaining abroad the armor and the gun steel for the authorized ships. It would seem desirable that the wants of the Army and the Navy in this regard should be reasonably met, and that by uniting their contracts such inducement might be offered as would result in securing the domestication of these important interests. The affairs of the postal service show marked and gratifying improvement during the past year. A particular account of its transactions and condition is given in the report of the Postmaster-General, which will be laid before you.
