Mr. Seward to Mr. Koerner.

No. 73.]

Sir: I have the honor to acknowledge the receipt of your despatch of February 28, No. 78, and to inform you that the manner in which you have executed my instructions to communicate with her Catholic Majesty’s government concerning the slave trade in Cuba is entirely approved.

I thank you for the copy of the publication made by the Condé de Reus, containing the results of his observations in America. The article has been already transferred to our journals, and it has given much satisfaction to the American people.

WILLIAM H. SEWARD.
