In compliance with a resolution of the Senate of the 19th of February last, requesting a statement of all the expenses annually incurred in carrying into effect the act of March 2, 1819, for prohibiting the slave trade, including the cost of keeping the ships of war on the coast of Africa and all the incidental expenses growing out of the operation of that act, I transmit a report from the Secretary of the Navy, with the statement, so far as it can be made, required by the resolution.
