I had soon afterwards the sorrow to learn from official documents from the Custom-house, that these little vessels actually cleared out for Africa, and that now nothing could be related so barbarous of this traffic, which might not instantly be believed.
In pursuing my different objects there was one, which, to my great vexation, I found it extremely difficult to attain.

This was the procuring of any assurance from those who had been personally acquainted with the horrors of this trade, that they would appear, if called upon, as evidence against it.

My friend Harry Gandy, to whom I had been first introduced, had been two voyages, as I before mentioned; and he was willing, though at an advanced age, to go to London, to state publicly all he knew concerning them.

But with respect to the many others in Bristol, who had been to the coast of Africa, I had not yet found one who would come forward for this purpose.

There were several old Slave Captains living there, who had a great knowledge of the subject.
