INTRODUCTION. THE story of slavery never has been and never will be fully told. In the last letter that John Wesley ever wrote, addressed to Wilberforce, the great abolitionist, and dated February 24, 1791, and this only six days before his tireless hand was quieted in death, he wrote these words: "I see not how you can go through your glorious enterprise in opposing that execrable villainy" (slavery and the slave-trade), "which is the scandal of religion, of England, and of human nature. Unless God has raised you up for this very thing you will be worn out by the opposition of men and devils; but if God be for you who can be against you? Are all of them together stronger than God? O, 'be not weary in well doing.' Go on in the name of God and the power of his might till even American slavery, the vilest that ever saw the sun, shall vanish away before it." It is because American slavery was "the vilest that ever saw the sun" that it is and will remain forever impossible to adequately portray its unspeakable horrors, its heartbreaking sorrows, its fathomless miseries of hopeless grief, its intolerable shames, and its heaven-defying and outrageous brutalities.
