Considered geologically, the Island of Goree is a group of basaltic columns still standing, but a part of which seem to have experienced the action of the same cause of destruction and overthrow, as the columns of the same formation of Cape Verd, because they are inclined and overthrown in the same direction.

Cape Verd is a peninsula about five leagues and a half long; the breadth is extremely variable. At its junction, with the continent, it is about four leagues broad; by the deep recess which the Bay of Daccard forms, it is reduced, near that village, to 600 toises, and becomes broader afterwards. This promontory, which forms the most western part of Africa, is placed, as it were, at the foot of a long hill, which represents the ancient shore of the continent. On the sea-shore, and towards the north-east, there are two hills of unequal height, which serve as a guide to mariners; and which, from the substances collected in their neighbourhood, evidently shew that they are the remains of an ancient volcano. They have received the name of Mamelles. From this place, to the western extremity of the Peninsula, the country rises towards the north-east, and terminates in a sandy beach on the opposite side.

Almost the whole north-side is composed of steep rocks, covered with large masses of oxyd of iron, or with regular columns of basalt which, for the most part, still preserve their vertical position. Their summits, which are sometimes scorified, seem to prove that they have been exposed to a great degree of heat. The soil which covers the plateau, formed by the summit of the Basaltic columns, the sides of which assume towards the Mamelles, the appearance of walls of Trapp, but already, in a great degree, changed into tuf, is arid and covered with briars. The soil of the Mamelles, like almost all that of the middle of the Peninsula, which appears to lie upon argillaceous lava, in a state of decomposition, is much better. There are even to be found, here and there, some spots that are very fertile; this is the arable land of the inhabitants. Towards the south, all resumes more or less, the appearance of a desert; and the sands, though less destitute of vegetable mould, extend from thence to the sea-shore. It is by manuring the land, with the dung of their cattle, that the Negroes raise pretty good crops of sorgho. The population of this peninsula may be estimated at ten thousand souls. It is entirely of the Yoloffe race, and shews much attachment to all the ceremonies of Islamism. The Marabous or Priests, sometimes mounted on the top of the Nests of the Termites, or on the walls surrounding their mosque, call the people several times a-day to prayer.

The social state of this little people, is a kind of republic governed by a senate, which is composed of the chiefs of most of the villages. They have taken from the Coran the idea of this form of government, as is the case with most of those, established among the nations who follow that law.

At the time of the expedition of the Medusa this senate was composed as follows:

Moctar, supreme chief resident of Daccard.
Diacheten, chief of the village of Sinkieur.
Phall Yokedieff.
Tjallow-Talerfour Graff.
Mouim Bott.
Bayémour Kayé.
Modiann Ketdym.
Mamcthiar Symbodioun.
Ghameu Wockam.
Diogheul, chief of the village of Gorr.
Baindonlz Yoff.
Mofall Ben.
Schenegall Bambara.

This tribe was formerly subject to a Negro King in the neighbourhood; but having revolted against him, though very inferior in numbers, it defeated his army a few years ago. The bones of the vanquished, that still lie scattered on the plain, attest the victory. A wall, pierced with loop-holes, which they erected in the narrowest part of the Peninsula, and which the enemy was unable to force, chiefly contributed to their success. The Yolloffes are in general handsome and their facial angle has hardly any thing of the usual deformity of the Negroes. Their common food is cous-cous, with poultry, and above all fish; their drink is brackish water, mixed with milk and sometimes with palm wine. The poor go on foot, the rich on horseback, and some ride upon bulls, which are always very docile, for the Negroes are eminently distinguished by their good treatment of all animals. Their wealth consists in land and cattle; their dwellings are generally of reeds, their beds are mats made of Asouman (maranta juncea) and leopards' skins; and their cloathing broad pieces of cotton. The women take care of the children, pound the millet, and prepare the food; the men cultivate the land, go a hunting and fishing, weave the stuff for their clothes, and gather in the wax.

Revenge and idleness seem to be the only vices of these people; their virtues are charity, hospitality, sobriety, and love of their children. The young women are licentious, but the married women are generally chaste and attached to their husbands. Their diseases among the children, are worms, and umbilical hernia; among the old people, and particularly those who have travelled much, blindness and opthalamia; and among the adult, affections of the heart, obstructions, sometimes leprosy, and rarely elephantiasis. Among the whole population of the Peninsula, there is only one person with a hunch back, and two or three who are lame. During the day they work or rest; but the night is reserved for dancing and conversation. As soon as the sun has set, the tambourine is heard, the women sing; the whole population is animated; love and the ball set every body in motion. "Africa dances all the night," is an expression which has become proverbial among the Europeans who have travelled there.

There is not an atom of calcareous stone in the whole country: almost all the plants are twisted and thorny. The Monbins are the only species of timber that are met with. The thorny asparagus, A. retrofractus, is found in abundance in the woods; it tears the clothes, and the centaury of Egypt pricks the legs. The most troublesome insects of the neighbourhood are gnats, bugs, and ear-wigs. The monkey, called cynocephalus, plunders the harvests, the vultures attack the sick animals, the striped hyoena and the leopard prowl about the villages during the night; but the cattle are extremely beautiful, and the fish make the sea on this coast boil, and foam by their extraordinary numbers. The hare of the Cape and the gazell are frequently met with. The porcupines, in the moulting season, cast their quills in the fields, and dig themselves holes under the palm trees. The guinea-fowl (Pintada), the turtle-dove, the wood-pigeon are found every where. In winter immense flocks of plovers of various species, are seen on the edges of the marshes, and also great numbers of wild ducks. Other species frequent the reeds, and the surface of the water is covered with geese of different kinds, among which is that whose head bears a fleshy tubercle like that of the cassowary. The fishing nets are made of date leaves; their upper edge is furnished, instead of cork, with pieces of the light wood of the Asclepias.—The sails of the canoes are made of cotton.

Several shrubs, and a large number of herbaceous plants of this part of Africa, are found also in the Antilles. But among the indigenous plants, are the Cape Jessamine, the Amaryllis Rubannée, the Scarlet Hoemanthus, the Gloriosa Superba, and some extremely beautiful species of Nerions. A new species of Calabash, (Crescentia) with pinnated leaves is very common. Travellers appear to have confounded it with the Baobab, on account of the shape of its fruits, the thickness of its trunk, and the way in which its branches grow. Its wood, which is very heavy and of a fallow colour, has the grain and smell of ebony: its Yoloffe name is Bonda, the English have cut down and exported the greatest part of it.
