Little further remains to be said of Delagoa Bay, though many interesting facts might have been elicited in relation to the slave-trade, had the Nemesis remained there longer. It appears very evident that formerly the trade was carried on with greater atrocity than at present, but enough is still known respecting it to make us look upon the natives themselves as the worst abettors of the traffic. The passions of the savage chiefs seem only to be withheld for a moment, not suppressed, by the difficulty of procuring slaves; and when they can neither find enemies to seize, nor _culprits to condemn_, they sometimes send a sort of marauding expedition to seize by treachery _their own people_, and sell them into slavery. It is stated by Captain Owen, that, within even a few years, under a former commandant, some of the chiefs had been persuaded to sell their harmless subjects for so trifling a sum as a dollar and a half each, or about seven shillings, to be paid, not in money, but in merchandize of trifling value, and that several cargoes had been obtained in this way for the Brazilian market. If we look for the most thriving mart for slaves upon the east coast of Africa at the present time, we shall find it at the river Quillimane, a little more than five hundred miles to the north of Delagoa Bay. It lies about midway between that settlement and Mozambique. There the slaves are purchased for coarse cloth, gunpowder, beads, cutlery, &c.; and the "arrival of one of the little traders, with his pedler-kind of stock, among one of the native tribes in the interior, becomes the signal for general warfare, in which the weak become the victims of the strong." A few years ago, no less than five thousand slaves were annually exported, from this mart alone, to Rio Janeiro. It is indeed astonishing that a place so unhealthy in itself as Quillimane should be able to keep up its constant supply of human export. The soil and the very air are no less pestilential than the traffic which debases it; but the effects of the demand are felt far and wide, and, hundreds of miles in the interior, the slave hunt, as it may be called, is carried on; and the ramifications of this odious traffic spread themselves like the branches of the upas-tree, not merely poisoning all within its shade, but becoming more and more infectious as it branches out further from the root. CHAPTER VII. All preparations being at length completed, on the morning of the 17th of August, just twenty days after having so providentially succeeded in reaching her port of refuge, the Nemesis was once more ready to continue her voyage.
