Estimating slaves at 20_l_. each; ivory, 350_l_.; camwood, 25_l_.; rice, 10_l_.; wax, 100_l_.; and Malaguetta pepper, 10_l_. per ton, at first cost upon the coast of Africa; the whole produces the sum of 305,500_l_. sterling; to which may be added a three-fold export to leeward, which will make an aggregate amount of nearly _one million_ sterling. In addition to the foregoing exemplification, we have to contemplate the great multiplicity of natural productions, abounding in this extent of region, namely, indigo, numerous plants for staining, cotton in wild exuberance, cocoa, coffee, and aromatic plants, &c. &c. Wild bees are so extremely numerous, that wax forms an important article of trade which might be considerably increased; substances proper for making soap are also to be found in great abundance, raw hides, more especially in the Gambia, and the countries insular to the Rio Noonez and Rio Pongo; gold is procured from Bambouk, and tobacco is found in every direction, which might be greatly increased by cultivation and an improved soil; cattle, poultry, Guinea hens, different species of game, fish, with other animals; fruits, and a variety of vegetable productions, calculated to satisfy every luxurious want and desire. To these objects of commerce may be added, the now important article of sugar, which might be raised to a great amount, in various districts of Africa, as the climate is propitious to the growth of the sugarcane, which, under proper cultivation, might be raised in great perfection. The lands upon the banks of the Gambia, the Rio Noonez, the Rio Grande, the Rio Pongo, in the Mandingo country, Sierra Leone, Sherbro, &c. are universally allowed to be extremely fertile in many places, and abundant in vegetation and population. These countries produce various hard woods, well adapted to cabinet work and ship building, and are singular in their qualites and properties. The most remarkable are, 1st. the cevey, or kinney wood, which grows about the size of the oak, in England, and may be cut into planks of 20 feet by 15 inches. Its texture is something of the ash grey and mahogany, variegated with stripes, fancifully disposed, and is therefore adapted to cabinet work; its qualities for ship building are peculiar, having the virtue of resisting the worm and vermis, so destructive to shipping in tropical climates, and corroding iron; it grows in great abundance. Any quantity of this wood put into water sufficient to cover it, will, in a few hours, produce an unctuous substance floating on the top, resembling verdigrise, and of a poisonous quality.
