IN presenting to the British Public the Autobiography of a Negro Slave, it may be expected of me, as Editor, to state the circumstances under which this narrative came into my hands, and my reasons for believing that it is really what it professes to be, namely, The Life, Adventures, and Experiences of an African Prince, named Zamba, who succeeded his father as the King of a small territory on the banks of the Congo, and who was inveigled by the captain of an American slaver, and sold as a slave at Charleston, in South Carolina. This I am willing to do for the sake of truth and justice, although, in thus publicly avowing my participation in Zamba's attacks upon slavery and slaveowners, I am quite aware that I shall provoke the displeasure of many individuals now resident in Charleston, whom I regard as my personal friends, and, no doubt, I shall also incur the odium of all who are in favour of the continuance of negro slavery. I could not comply with the request of the Publishers of the work, that I would afford them an opportunity of communicating directly with Zamba; for (though it may not be generally known in this country) a letter addressed to a coloured person in Charleston by his proper name, would be opened at the post-office of that city, and in such a case as the present, Zamba's life would not be worth an hour's purchase.
