Estimates of appropriations for the support of the military establishment for the fiscal year ending June 30, 1878, were transmitted to Congress by the former Secretary of the Treasury at the opening of its session in December last. These estimates, modified by the present Secretary so as to conform to present requirements, are now renewed, amounting to $32,436,764.98, and, having been transmitted to both Houses of Congress, are submitted for your consideration. There is also required by the Navy Department $2,003,861.24. This sum is made up of $1,446,688.16 due to officers and enlisted men for the last quarter of the last fiscal year; $311,953.50 due for advances made by the fiscal agent of the Government in London for the support of the foreign service; $50,000 due to the naval-hospital fund; $150,000 due for arrearages of pay to officers, and $45,219.58 for the support of the Marine Corps. There will also be needed an appropriation of $262,535.22 to defray the unsettled expenses of the United States courts for the fiscal year ending June 30 last, now due to attorneys, clerks, commissioners, and marshals, and for rent of court rooms, the support of prisoners, and other deficiencies. A part of the building of the Interior Department was destroyed by fire on the 24th of last month. Some immediate repairs and temporary structures have in consequence become necessary, estimates for which will be transmitted to Congress immediately, and an appropriation of the requisite funds is respectfully recommended. The Secretary of the Treasury will communicate to Congress, in connection with the estimates for the appropriations for the support of the Army for the current fiscal year, estimates for such other deficiencies in the different branches of the public service as require immediate action and can not without inconvenience be postponed until the regular session. I take this opportunity also to invite your attention to the propriety of adopting at your present session the necessary legislation to enable the people of the United States to participate in the advantages of the International Exhibition of Agriculture, Industry, and the Fine Arts which is to be held at Paris in 1878, and in which this Government has been invited by the Government of France to take part. This invitation was communicated to this Government in May, 1876, by the minister of France at this capital, and a copy thereof was submitted to the proper committees of Congress at its last session, but no action was taken upon the subject. The Department of State has received many letters from various parts of the country expressing a desire to participate in the exhibition, and numerous applications of a similar nature have also been made at the United States legation at Paris.
