Dr. James Hall, the Secretary of the Maryland Colonization Society, informs us that the average cost of sending negroes to Liberia does not exceed thirty dollars each; and it is his opinion that arrangements might be made on an extensive plan for conveying them thither at an average expense of not more than twenty-five dollars each. The American colonization movement, as now systematized and conducted, is simply an American humane farce. At present the slaves are increasing in this country at the rate of nearly one hundred thousand per annum; within the last ten years, as will appear below, the American Colonization Society has sent to Liberia less than five thousand negroes. Emigrants sent to Liberia by the American Colonization Society, during the ten years ending January 1st, 1857.

Fiddlesticks for such colonization! Once for all, within a reasonably short period, let us make the slaveholders do something like justice to their negroes by giving each and every one of them his freedom, and sixty dollars in current money; then let us charter all the ocean steamers, packets and clipper ships that can be had on liberal terms, and keep them constantly plying between the ports of America and Africa, until all slaves shall enjoy freedom in the land of their fathers. Under a well-devised and properly conducted system of operations, but a few years would be required to redeem the United States from the monstrous curse of negro slavery.
