Extract
The coastline of West Africa lies between Cape Verde and Mount Cameroon. This is a distance of approximately 2400 miles, but it only contains two good natural harbours - those at Dakar and Freetown. Both of these are situated in the extreme west of the region, while the remainder of the seaboard provides few satisfactory port sites because of the presence of esturine bars, heavy surf, shallow lagoons, marshes or mangrove swamps.1 The land behind the coast consists mainly of tropical rain forests or savannah and these diverse areas have naturally developed two different cultures. The inhabitants of the forest lands near the coast, where the climate is hot and moist, have tended to live in small, inward-looking communities, with a subsistence economy based on a limited technology; whereas those who lived in the hot, dry climate of the savannah have more commonly joined together in larger societies which have enjoyed a more advanced economy and technology. Moreover, the existence of a coastal forest belt to the south, allied with the activities in the forest of the tsetse fly, has meant that the savannah areas of the interior were virtually isolated from the western seaboard. In these circumstances the trade that was undertaken tended to be relatively small and came overland from either the north or east of Africa.2
