President Lincoln sent to the Capitol an Anglo-American treaty to work together against the international slave trade: “I transmit to Congress a copy of a treaty for the suppression of the African slave trade, between the United States and her Britannic Majesty, signed in this city on the 7th of April last, and the ratifications of which were exchanged at London on the 20th ultimo.”
A copy of the correspondence which precede the conclusion of the instrument, between the Secretary of State and Lord Lyons, her Britannic Majesty’s envoy extraordinary and minister plenipotentiary, is also herewith transmitted.
It is desirable that such legislation as may be necessary to carry the treaty into effect should be enacted as soon as may compart with the convenience of Congress.
Illinois Senator Orville H. Browning: “At night went to see the President about an exchange of the rebel [General Simon Bolivar] Buckner for Genl Prentiss &c. The Kentucky delegation are all opposed to Buckner being given up, but the President is very much disposed to let him go, not attaching much importance to him any way or any where, either in prison or out of it.”
