In compliance with a resolution of the Senate of the 15th instant, I transmit herewith a copy of the report of the commission appointed by the President on the 15th of March, 1872, relating to the different interoceanic canal surveys and the practicability of the construction of a ship canal across this continent.

[Footnote 25: See pp. 547-548.] EXECUTIVE MANSION, _May 26, 1879_. _To the Senate of the United States_: In response to a resolution of the Senate of the 14th instant, I transmit herewith a communication[26] from the Secretary of the Interior and accompanying papers. R.B. HAYES. [Footnote 26: Relating to lands in the Indian Territory acquired by the treaties of 1866.] EXECUTIVE MANSION, _June 5, 1879_. _To the Senate and House of Representatives_: I transmit herewith the "proceedings and report" of the board of officers convened by Special Orders, No. 78, Headquarters of the Army, Washington, April 12, 1878, in the case of Fitz John Porter. The report of the board was made in March last, but the official record of the proceedings did not reach me until the 3d instant. I have given to this report such examination as satisfies me that I ought to lay the proceedings and conclusions of the board before Congress. As I am without power, in the absence of legislation, to act upon the recommendations of the report further than by submitting the same to Congress, the proceedings and conclusions of the board are transmitted for the information of Congress and such action as in your wisdom shall seem expedient and just. R.B. HAYES. WASHINGTON, _June 13, 1879_. _To the House of Representatives_: I transmit herewith, in compliance with the resolution of the House of Representatives of the 29th ultimo, a report of the Secretary of State relative to the steps taken by this Government to promote the establishment of an interoceanic canal across or near the Isthmus of Darien. R.B. HAYES. WASHINGTON, _June 23, 1879_. _To the Senate of the United States_: I transmit herewith to the Senate a report from the Secretary of State, in response to a resolution of that body of the 20th instant, calling for the proceedings and accompanying papers of the International Silver Conference held in Paris in 1878. R.B. HAYES. EXECUTIVE MANSION, _June 30, 1879_. _To the Senate and House of Representatives_:
