Plan of the Monograph. This monograph proposes to set forth the efforts made in the United States of America, from early colonial times until the present, to limit and suppress the trade in slaves between Africa and these shores. The study begins with the colonial period, setting forth in brief the attitude of England and, more in detail, the attitude of the planting, farming, and trading groups of colonies toward the slave-trade. It deals next with the first concerted effort against the trade and with the further action of the individual States. The important work of the Constitutional Convention follows, together with the history of the trade in that critical period which preceded the Act of 1807. The attempt to suppress the trade from 1807 to 1830 is next recounted. A chapter then deals with the slave-trade as an international problem. Finally the development of the crises up to the Civil War is studied, together with the steps leading to the final suppression; and a concluding chapter seeks to sum up the results of the investigation. Throughout the monograph the institution of slavery and the interstate slave-trade are considered only incidentally.
