Secondly, the dunjay wood, rather coarser in the grain, but harder in quality than the Spanish Bay mahogany. It possesses the same peculiarities as the cevey or kinney, in resisting the worm in salt water, and corroding iron. It may be procured in any quantity. And, Thirdly, the melley wood, or _gris-gris_ tree, another species of mahogany, abundant in growth, having a more rare quality than the foregoing, resisting the worm in both salt and fresh water; it is extremely hard, and its juices so poisonous, in the premature state, as to cause instant death. The manifold and neglected productions of this extraordinary continent require only to be developed, and when the useful arts of Europe are introduced here, ample recompense will attend the benevolent undertaking, natural history will be much enlarged, and mankind be greatly benefited. The claims of humanity, the distinguished part it has taken in an unnatural and much to be deplored commerce, loudly unite with a wise policy, in one impressive appeal to the feelings of the more refined inhabitants of Europe, and to none more than those of Englishmen. The goods adapted to African commerce are, _East India goods_--consisting of bafts, byrampauats, chilloes, romals, neganipauts, niccanees, red and blue chintz, Guinea stuffs, bandanoes, sastracundies, &c. _Manchester goods_.--Cotton chilloes, cushtaes, neganipauts, photaes, romal handkerchiefs, silk handkerchiefs, &c. _Linen Britanias_, slops, spirits, tobacco, guns, swords, trade chests, cases, jars, powder, umbrellas, boats, canvas, cordage, pitch, tar, paints, oil, and brushes, empty kegs, kettles, pans, lead basons, earthenware, hardware, beads, coral, iron bars, lead bars, common caps, Kilmarnock ditto, flints, pipes, leg and hand manilloes, snuff boxes, tobacco boxes, cargo hats, fine ditto, hair trunks, knives, looking glasses, scarlet cloth, locks, shot, glass ware, stone ware, provisions, bottled ale and porter, &c. &c. The foregoing general enumeration may serve to convey a just conception of the various manufactures requisite in the African trade, and the different branches to which it is allied, yeilding support to a numerous body of merchants, manufacturers, artizans, and many of the labouring class of the community. Generally speaking, the Africans are unacquainted with specie as a circulating medium of commerce, although they form to themselves an ideal standard, by which they estimate the value of the commodities in barter; this, however, fluctuates on various parts of the coast. From Senegal to Cape Mesurado, the medium of calculation is termed a _bar_; from thence to the eastward of Cape Palmas, the computation is in _rounds_; and on the Gold Coast in _ackies_ of gold, equal to 4_l_. sterling, and of trade only half that value. At Goree the bar, under the French, was 4, pieces of 24 sous, and 1 of 6; but at present the bar is considered a dollar.
