He well knew that the advocates for the Slave-trade had endeavoured to represent the project for abolition as a branch of jacobinism; but they, who supported it, proceeded upon no visionary motives of equality or of the imprescriptible rights of man. They strenuously upheld the gradations of civil society: but they did indeed affirm that these gradations were, both ways, both as they ascended and as they descended, limited. There was an existence of power, to which no good king would aspire; and there was an extreme condition of subjection, to which man could not be degraded without injustice; and this they would maintain was the condition of the African, who was torn away into slavery. He then explained the limits of that portion of Africa, which the bill intended to set apart as sacred to peace and liberty. He showed that this was but one-third of the coast; and therefore that two-thirds were yet left for the diabolical speculations of the slave-merchants. He expressed his surprise that such witnesses as those against the bill should have been introduced at all. He affirmed that their oaths were falsified by their own log-books; and that from their own accounts the very healthiest of their vessels were little better than pestilential gaols. Mr. Robert Hume, one of these witnesses, had made a certain voyage. He had made it in thirty-three days. He had shipped two hundred and sixty-five slaves, and he had lost twenty-three of them. If he had gone on losing his slaves, all of whom were under twenty-five years of age, at this rate, it was obvious, that he would have lost two hundred and fifty-three of them, if his passage had lasted for a year. Now in London only seventeen would have died, of that age, out of one thousand within the latter period. After having exposed the other voyages of Mr. Hume in a similar manner, he entered into a commendation of the views of the Sierra Leone company; and then defended the character of the Africans in their own country, as exhibited in the Travels of Mr. Mungo Park. He made a judicious discrimination with respect to slavery, as it existed among them. He showed that this slavery was analogous to that of the heroic and patriarchal ages; and contrasted it with the West Indian in an able manner.
