A doubt immediately arose as to the true construction of this act. It is quite clear from its terms that the President was authorized to provide "for the safe-keeping, support, and removal" of these negroes up till the time of their delivery to the agent on the coast of Africa, but no express provision was made for their protection and support after they had reached the place of their destination. Still, an agent was to be pointed to receive them in Africa, and it could not have been supposed that Congress intended he should desert them at the moment they were received and turn them loose on that inhospitable coast to perish for want of food or to become again the victims of the slave trade. Had this been the intention of Congress, the employment of an agent to receive them, who is required to reside on the coast, was unnecessary, and they might have been landed by our vessels anywhere in Africa and left exposed to the sufferings and the fate which would certainly await them. Mr. Monroe, in his special message of December 17, 1819, at the first session after the act was passed, announced to Congress what in his opinion was its true construction. He believed it to be his duty under it to follow these unfortunates into Africa and make provision for them there until they should be able to provide for themselves. In communicating this interpretation of the act to Congress he stated that some doubt had been entertained as to its true intent and meaning, and he submitted the question to them so that they might, "should it be deemed advisable, amend the same before further proceedings are had under it." Nothing was done by Congress to explain the act, and Mr. Monroe proceeded to carry it into execution according to his own interpretation. This, then, became the practical construction. When the Africans from on board the Echo were delivered to the marshal at Charleston, it became my duty to consider what disposition ought to be made of them under the law. For many reasons it was expedient to remove them from that locality as speedily as possible. Although the conduct of the authorities and citizens of Charleston in giving countenance to the execution of the law was just what might have been expected from their high character, yet a prolonged continuance of 300 Africans in the immediate vicinity of that city could not have failed to become a source of inconvenience and anxiety to its inhabitants. Where to send them was the question. There was no portion of the coast of Africa to which they could be removed with any regard to humanity except to Liberia. Under these circumstances an agreement was entered into with the Colonization Society on the 7th of September last, a copy of which is herewith transmitted, under which the society engaged, for the consideration of $45,000, to receive these Africans in Liberia from the agent of the United States and furnish them during the period of one year
