55. ~The Act of 1807.~ The first great goal of anti-slavery effort in the United States had been, since the Revolution, the suppression of the slave-trade by national law. It would hardly be too much to say that the Haytian revolution, in addition to its influence in the years from 1791 to 1806, was one of the main causes that rendered the accomplishment of this aim possible at the earliest constitutional moment. To the great influence of the fears of the South was added the failure of the French designs on Louisiana, of which Toussaint L'Ouverture was the most probable cause. The cession of Louisiana in 1803 challenged and aroused the North on the slavery question again; put the Carolina and Georgia slave-traders in the saddle, to the dismay of the Border States; and brought the whole slave-trade question vividly before the public conscience. Another scarcely less potent influence was, naturally, the great anti-slavery movement in England, which after a mighty struggle of eighteen years was about to gain its first victory in the British Act of 1807. President Jefferson, in his pacificatory message of December 2, 1806, said: "I congratulate you, fellow-citizens, on the approach of the period at which you may interpose your authority constitutionally, to withdraw the citizens of the United States from all further participation in those violations of human rights which have been so long continued on the unoffending inhabitants of Africa, and which the morality, the reputation, and the best interests of our country, have long been eager to proscribe. Although no law you may pass can take prohibitory effect till the first day of the year one thousand eight hundred and eight, yet the intervening period is not too long to prevent, by timely notice, expeditions which cannot be completed before that day."[1] In pursuance of this recommendation, the very next day Senator Bradley of Vermont introduced into the Senate a bill which, after a complicated legislative history, became the Act of March 2, 1807, prohibiting the African slave-trade.[2] Three main questions were to be settled by this bill: first, and most prominent, that of the disposal of illegally imported Africans; second, that of the punishment of those concerned in the importation; third, that of the proper limitation of the interstate traffic by water.
