Another argument which, especially in the outset of the discussion, was strongly, and with great confidence, urged against us by our opponents, was, that the African Trade is a nursery for seamen; and that its abolition would therefore be highly injurious to our naval strength. This part of the subject was very early taken up by Mr. Clarkson, a gentleman whose services, throughout the whole conduct of this great cause, deserve the highest commendation. He asserted, as the result of a long and laborious inquiry, that of the sailors employed in the African Trade, between a fifth and a sixth actually died; and that the African ships seldom brought home more than half of their original crews. Nothing was more vehemently repelled, or more obstinately denied, than these positions, till, at length, having long borne with these clamorous contradictions, the muster rolls of the African ships were moved for and laid before Parliament; documents which had been kept in the possession of our opponents, and which cannot therefore be supposed to have been fabricated or coloured to serve our purpose. From these papers Mr. Clarkson’s calculations were fully justified. It appeared, that of 12,263 persons, the number of the original crews, there had died 2,643, the average length of their voyages being twelve months; whilst, on the contrary, in the West Indian trade, in which the length of the voyage was seven months, of 7,640, the number of the original crews, there had died only 118. But the loss by deaths was not the whole loss to the country; for, besides the broken constitutions of the survivors, which rendered many of them, for the rest of their lives, incapable of the duties of their profession, so many left their ships in consequence of ill usage, that they seldom brought home more than half the persons they had taken out. This last circumstance was attempted to be accounted for, from the natural capriciousness of sailors; and it was said, that they ran away in as great number from the West India as from the Guinea ships. The direct contrary appeared from the muster rolls, and this too, though, from the different ways of paying them in the two trades, their forfeiting little or nothing by quitting the West Indiamen, but much by quitting the Guineamen, the reverse might have been naturally expected. Much more might be said on this subject. Especially, such scenes of cruelty towards those unhappy men might be opened to your view, as would excite at once the concern and indignation of every man, who feels for that class of his fellow-citizens to which this nation owes so much both of her security, her affluence, and her glory.
