Mr. Seward to Mr. Riotte.

No. 19.]

Your despatch of the 15th of May, (No. 33,) has been received, and also a copy of a note which has been addressed to you by the minister of foreign affairs of the republic of Costa Rica.

In that paper the minister alludes to a project which is under consideration in that republic, by which its government should set aside a part of the national domain upon the sea-coast for the foundation of a colony, to consist of free negroes who should emigrate from the United States, and occupy the territory under arrangements to be made between the two republics. The subject has been submitted to the President.

The free negroes of the United States enjoy the right of remaining within the federal Union, and the right of emigrating from it whithersoever to them may seem best. The government of the United States exercises no power or influence in determining their choice. Congress has made a small appropriation to enable the President to assist such as may choose to colonize in any foreign country. That appropriation will be expended under the direction of the President, in accordance with the views of Congress.

Several states have expressed, more or less directly, a desire to avail themselves of the benefit of the migration of persons of that class, and have made known to this government their readiness to offer inducements to them more or less liberal. The government has decided to allow these inducements to be submitted to the persons invited to emigrate in the presence of some official agent, who will be instructed to guard the free colored population against possible imposition or misappropriation. Such persons of that class as may intelligently accept the invitation of any foreign state will, of course, find no obstacles interposed to their emigration, and the government will, at the same time, endeavor to take care that the inducements offered shall be realized. If Costa Rica should decide to submit a project to the United States of the character indicated by the minister in his note, all facilities for bringing it to the notice of the parties concerned will be afforded, as has been done in other cases.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

Charles N. Riotte, Esq., &c., &c., &c.
