I transmit to Congress a copy of a correspondence between the Secretary of State and the acting chargé d'affaires of the United States at Guayaquil, in the Republic of Ecuador, from which it appears that the Government of that Republic has failed to pay the first installment of the award of the commissioners under the convention between the United States and Ecuador of the 25th November, 1862, which installment was due on the 17th of February last. As debts of this character from one government to another are justly regarded as of a peculiarly sacred character, and as further diplomatic measures are not in this instance likely to be successful, the expediency of authorizing other proceedings in case they should ultimately prove to be indispensable is submitted to your consideration. ANDREW JOHNSON. WASHINGTON, D.C., _May 10, 1866_. _To the House of Representatives_: I transmit herewith a report from the Secretary of the Treasury, in answer to the resolution of the House of Representatives of the 3d instant, requesting information concerning discriminations made by the so-called Maximilian Government of Mexico against American commerce, or against commerce from particular American ports. ANDREW JOHNSON. WASHINGTON, _May 11, 1866_. _To the House of Representatives_: I transmit a report from the Secretary of State, in answer to that part of the resolution of the House of Representatives of the 7th instant which calls for information in regard to the clerks employed in the Department of State. ANDREW JOHNSON. WASHINGTON, _May 16, 1866_. _To the Senate and House of Representatives_: I transmit to Congress a copy of the correspondence between the Secretary of State and Cornelius Vanderbilt, of New York, relative to the joint resolution of the 28th of January, 1864, upon the subject of the gift of the steamer _Vanderbilt_ to the United States. ANDREW JOHNSON. EXECUTIVE MANSION, _Washington, May 7, 1866_. Hon. SCHUYLER COLFAX, _Speaker of the House of Representatives_.
