I transmit herewith, for consideration and appropriate action by Congress, a letter from the Secretary of the Navy, in relation to the proposed establishment of naval stations of the United States on the American Isthmus. In this paper the current testimony of prominent officers of this Government for a long series of years, as to the feasibility and necessity of establishing such stations and the great advantage to flow therefrom to the naval and commercial interests of the United States, is clearly set forth, and the considerations adduced can not but commend themselves, I am confident, to the careful attention of Congress. Convinced of the wisdom and propriety of the suggestions thus presented, I recommend to Congress the appropriation of the sum named by the Secretary of the Navy, to be at his disposal at once, for expenditure as soon as suitable arrangements can be made to the proposed end. R.B. HAYES. EXECUTIVE MANSION, _February 4, 1881_. _To the Senate and House of Representatives_: I herewith transmit a communication from the Secretary of the Navy, with reference to the dispatch of a vessel for the relief of the _Jeannette_ polar expedition, and commend the recommendations of the Secretary to the prompt and favorable action of Congress. R.B. HAYES. EXECUTIVE MANSION, _February 14, 1881_. _To the Senate and House of Representatives_: I herewith transmit the final report addressed to me by the commissioners appointed under the act of Congress approved July 19, 1876, authorizing the repavement of that part of Pennsylvania avenue lying between the Treasury Department and the Capitol Grounds. R.B. HAYES. WASHINGTON, _February 17, 1881_. _To the House of Representatives_: I transmit herewith a report of the Secretary of State, in response to the resolution addressed to him by the House of Representatives of the 31st of January ultimo, on the subject of international action for the restoration of silver to full use as money. The prospect of an early international conference, promising valuable results in accordance with the interests of this country, is such that I recommend to the immediate attention of Congress an appropriation providing for the proper representation of this Government at such conference. R.B. HAYES. WASHINGTON, _February 21, 1881_. _To the Senate of the United States_:
