Mr. Seward to Mr. Yrisarri.

The undersigned, Secretary of State of the United States, has the honor to acknowledge the receipt of a note addressed to him on the 9th instant by his excellency Mr. Yrisarri, minister plenipotentiary of the republics of Guatemala and Salvador, touching the subject of the colonization of Americans of African derivation in those republics.

The undersigned has the honor to inform Mr. Yrisarri, in reply, that while any agents of such persons, recognized by this government, will, in every case, be instructed not to attempt any such colonization in any country without first having received the consent of its government to the settlement of the colonists, such agents will be especially instructed not to carry such emigrants at all to either of the two republics represented by Mr. Yrisarri, his note being accepted as a definitive expression of the purpose of these two governments not to receive and protect such settlements.

The undersigned avails himself of this occasion to renew to Mr. Yrisarri the assurances of his high consideration.

WILLIAM H. SEWARD.

Señor Don Antonio Jose De Yrisarri, &c., &c., &c. Brooklyn.
