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 thereafter with comfortable shelter, clothing, provisions, and medical attendance, causing the children to receive schooling, and all, whether children or adults, to be instructed in the arts of civilized life suitable to their condition.  This aggregate of $45,000 was based upon an allowance of $150 for each individual; and as there has been considerable mortality among them and may be more before they reach Africa, the society have agreed, in an equitable spirit, to make such a deduction from the amount as under the circumstances may appear just and reasonable.  This can not be fixed until we shall ascertain the actual number which may become a charge to the society.  It was also distinctly agreed that under no circumstances shall this Government be called upon for any additional expenses.  The agents of the society manifested a laudable desire to conform to the wishes of the Government throughout the transaction.  They assured me that after a careful calculation they would be required to expend the sum of $150 on each individual in complying with the agreement, and they would have nothing left to remunerate them for their care, trouble, and responsibility.  At all events, I could make no better arrangement, and there was no other alternative.  During the period when the Government itself, through its own agents, undertook the task of providing for captured negroes in Africa the cost per head was very much greater.

There having been no outstanding appropriation applicable to this purpose, I could not advance any money on the agreement.  I therefore recommend that an appropriation may be made of the amount necessary to carry it into effect.

Other captures of a similar character may, and probably will, be made by our naval forces, and I earnestly recommend that Congress may amend the second section of the act of March 3, 1819, so as to free its construction from the ambiguity which has so long existed and render the duty of the President plain in executing its provisions.
