In this system of prayer there is a mixture of fetishism, Mahomedanism, and a strong analogy to the Christian system; and it is no inconsiderable argument in favour of the mediation of the Saviour, that in the worship of heathen nations a mediator is uniformly associated with the object of adoration. Virgil in his Aeneid, and other classic writers, illustrate a belief of the ancient heathens in the omniscience of the deity, and they clearly elucidate the importance they attached the mediatorial efficacy of offerings and sacrifice. The form of worship adapted to the foregoing prayer, is to squat down upon the ground, placing the palm of their hands flat thereon twice, touching the earth the same number of times with their foreheads; then rubbing their arms from the wrist to the elbow, with that which is contracted by this operation, when the hands are applied to the face, and the forefingers put into the ears. I have dwelt more minutely upon this people and their present condition compared with the Foolahs, because I consider these nations have it much in their power to shut and open the paths of intercourse with the interior countries, therefore they become of importance, in the contemplation of any pursuits upon this district of Africa. The Mandingoes inhabiting Galam, and the countries interior to the Gambia, carry on the principal trade with those of Bambouk, &c. where gold is procured. This precious metal is obtained from the surface of the earth, and from the banks of the falls of the rivers in the rainy season; it is first washed in a calabash; and when the water is poured off, the dust, and sometimes large grains remain. The natives have no idea of mining; but it appears from hence, that mines of this metal must exist, which are concealed thro' the want of the arts of civilized life. The Mandingoes speak of these countries with a great air of mystery, and are extremely jealous, lest Europeans should obtain any information relative to them: as they carry on almost exclusively, this branch of commerce. When I was in the Bashia branch of the Rio Pongo, a meteor of an extraordinary kind appeared for two successive nights, directing its course from NE. to SW. which put the natives in a most dreadful state of consternation; the women fell into loud lamentations, the men beat their drums, and sent forth the most horrid yells; imagining, that this barbarous uproar would drive away the object of their fears. In eclipses of the sun and moon, they repeat their prayers and sacrifices, with the same clamour, under the notion that it will frighten away the monster which they suppose to obscure these planets from their view. These superstitious notions have the most powerful influence over the Negro's mind, and it is impossible to dissuade or reason him out of them.
