March 21, 1860
To the Senate of the United States:
In compliance with the request of the Senate contained in their resolution of yesterday, the 20th instant, I return to them the resolution of the 16th instant, "that the Senate do not advise and consent to the ratification of the treaty of friendship and commerce between the United States and Nicaragua, signed at Managua on the 16th day of March, 1859." I also return the treaty itself, presuming that the Senate so intended.
JAMES BUCHANAN.
