The allegations of these persons, even though they had not been effectually disproved by the concurrent testimony of the various classes of witnesses already noticed, carried their refutation on the very face of them. But if any doubts could have been entertained to which of the two accounts most credit was due, to that of men who were still concerned in carrying on the Slave Trade, or had made their fortunes by it, on the one side; and of witnesses on the other, most of whom, highly respectable both in point of rank and character, had no interest at stake either way; these doubts would have been completely removed by another branch of evidence. For, happily for the cause of truth and justice, we were able to adduce, in support of our allegations, the testimony of another set of witnesses, against whom our opponents at least could urge no objections, [Sidenote: Especially by accounts of Africa, published by Slave Traders, and before the Slave Trade had been attacked.] persons in the employ of the African Company or of private merchants, who had been long resident in Africa, for the express purpose of carrying on the Slave Trade, and who, as was formerly mentioned, had published to the world the result of their observations and experience. It might indeed have been feared, that we should be compelled to except against their testimony; and it must be confessed, that for the sake of their own credit, and for that of the occupation by which they had made their fortunes, they would naturally be disposed, even in acknowledging abuses, to touch them with a tender and favourable hand. Yet, however short of the truth we may reasonably suppose their representations to fall, where they are discreditable to the Slave Trade, we find our charges positively and abundantly proved.
