witnessed its torrent there, to be both an interesting and a pleasing
journey to go to the fountain-head, and then to travel on its banks
downwards, and to mark the different streams in each side, which should run
into it and feed it. So I presume the reader will not be a little
interested and entertained in viewing with me the course of the abolition
of the Slave-trade, in first finding its source, and then in tracing the
different springs which have contributed to its increase. And here I may
observe that, in doing this, we shall have advantages, which historians
have not always had in developing the causes of things. Many have handed
down to us events, for the production of which they have given us but their
own conjectures. There has been often indeed such a distance between the
events themselves and the lives of those who have recorded them, that the
different means and motives belonging to them have been lost through time.
On the present occasion, however, we shall have the peculiar satisfaction
of knowing that we communicate the truth, or that those, which we unfold,
are the true causes and means. For the most remote of all the human
springs, which can be traced as having any bearing upon the great event in
question, will fall within the period of three centuries, and the most
powerful of them within the last twenty years. These circumstances indeed
have had their share in inducing me to engage in the present history. Had I
measured it by the importance of the subject, I had been deterred: but
believing that most readers love the truth, and that it ought to be the
object of all writers to promote it, and believing moreover, that I was in
possession of more facts on this subject than any other person, I thought I
was peculiarly called upon to undertake it.

In tracing the different streams from whence the torrent arose, which has
now happily swept away the Slave-trade, I must begin with an inquiry as to
those who favoured the cause of the injured Africans from the year 1516 to
the year 1787, at which latter period a number of persons associated
