The palm tree, producing the oil so denominated, is one of the most useful trees to the African, yielding him meat, drink, and raiment. Where it grows, it is an indication of a good soil. It is remarkably tall, without branches, having regular and gradual protuberances, from the bottom towards the top, ending in five or six clusters of nuts, shaded by large deciduous leaves. The nuts, which are about the size of a hazle nut, have a hard kernel, encompassed by a clammy unctuous substance, covered by a thin skin, and the oil is produced from them by being exposed to the sun, which, by its influence, opens the juices; subsequent to this exposure, the nuts are put into a boiler full of water, and a liquid, in the process of boiling, flows upon the top, which when skimmed off, soon hardens and turns rancid; the kernel of the nut, after this process, is taken out of the boiler, beat in a paloon, and put into clear water, the shell of the nut sinks, and its contents float upon the surface, which, when skimmed as before, is finally put into a pot, fried, and carefully poured off, producing another kind of oil, used as butter, and having in a great degree its quality.
The wine is extracted from the tree by forming an incision at the bottom of every cluster of nuts, from each of which flows about a gallon of wine per day, for a week, when they are closed until the ensuing season. The liquid, when newly taken from the tree, resembles whey, and in that state has a sweetish agreeable taste, but it soon ferments and grows sour, changing to a strong vinegar of a disagreeable smell: in its fermented state it is most esteemed by the natives, and is productive of inebriety.
A substance overtops the clusters about 10 or 12 inches in diameter, and 3 or 4 feet in height, in a full grown tree, from whence proceeds a stalk, about 4 inches in length, which, on being boiled in water, makes an excellent vegetable resembling cabbage, or rather, in taste, the cauliflower; the leaves of the tree are converted by the natives into baskets, fishing nets, and cloth.
MEDICINAL PLANTS. Colla is highly esteemed by the natives, and they attribute to it the virtues of Peruvian bark; the Portuguese, ascribe the same quality to it, and dispatch from their factories small vessels to collect all they can procure.
Castor Oil Rhinum.-The bush which produces the bud from which this oil and valuable medicine is extracted, grows in great exuberance upon the Windward Coast, and its vicinity. A species of bark is in great abundance also, and is said to be equal in virtue to the Peruvian.
The foregoing enumeration of natural productions, is the result of unscientific enquiry only; but unquestionably, industrious and professional research, would discover infinitely more to philosophic and commercial contemplation, and develope the arcana of nature, dormant here through ignorance and barbarism.
On the 10th of May, I set out from Bance Island, with the view of exploring the two branches of the Sierra Leone river, the Rochelle, and the Port Logo. After rowing a few hours I arrived at the factory of Miffaré, formerly occupied by a Mr. Berauld, a Frenchman, but now attached to Bance Island.
Mr. Hodgkin, with his people, then in possession of the factory, accompanied me up the Port Logo branch the following morning, taking a number of towns in our way, and visiting the chiefs. The course of this branch of the river is extremely serpentine, and is navigable for light vessels to a little way from the town of Port Logo which is now the residence of Alimami, a Mandingo chief, who assumes the title of emperor. The banks are overgrown with the mangrove tree, interwoven together, so as to form an almost impenetrable thicket, excluding the air, which, with the extreme heat of the sun, and the noxious insects which are extracted by its rays from the swamps and woods, renders this navigation intolerably oppressive. The chief part of its trade is in slaves, camwood, and ivory, the latter, however, being small, although Port Logo commands a very extensive back country. When we came near the town of Port Logo, which is extremely difficult of approach at low water, we announced our visit by saluting in the manner of this country, which is what they call bush firing, or in other words is a continued irregular firing of musquetry.
It was soon discovered who we were, and crowds of natives flocked down from the upper town, which is situated on the declivity of a hill, to give us service, or to pay their respects. Our first visit was to Marriba, one of Alimami's head men, and a resident of what they consider the lower town.
Upon our arrival at Marriba's house, we found him at his devotions in the palaver-house, a shed under which the natives daily assemble to pray, or discuss public affairs. He received us with every demonstration of regard, and immediately offered his services to conduct us to Alimami. The old chief preceded us, with his long gold-headed cane, and our rear was brought up by a number of armed men, who had assembled to give us a favourable reception. Our salute had pleased Alimami, and being before known to him, he was determined to shew us every respect. The heat of the sun was almost intolerable, and before we arrived at the top of the hill where the imperial palace stood, I was nearly exhausted. The entrance to this large square of irregular mud buildings, is through a narrow passage or gate, forming an oblong square of mud, covered with thatch, and facing Alimami's house: we were ushered through this by one of his head men, and proceeded in the order we set out to Alimami, who was seated at the top of the square, surrounded by his chiefs, upon a mat spread upon a raised bank of mud, dressed in a turban, after the Turkish fashion, and a loose manding, robe, or shirt.
