=Natural Divisions.=—The Southern Provinces are conveniently divided for agricultural considerations into _wet_ and _dry_ zones. In the former the rainfall ranges from about 90 inches at Bendi to 250 inches at Opobo. In the latter zone the highest rainfall is reached in Lagos Town, where about 75 inches are annually registered; the lowest reading being that of 40 inches at Olokemeji. The densely forested area is practically entirely within the wet zone; this also including a tract of brackish-water forest (mangrove) and swamp. In the dry zone grass-land and open “bush,” with trees peculiar to such localities, occur, and it is in this portion of the country that most of the agricultural people are found. The inhabitants of the forested area in the wet zone give more attention to the collection of forest products, such as palm oil and rubber, and only grow sufficient grain and roots for their own consumption. =Inhabitants.=—The tribes found in the Western Province are chiefly Yorubas, and among these are some of the most intelligent people in the country. In the Central Province there are a large number of tribes speaking different languages, but among these the Benis are perhaps of most importance. The Ijoas, Ibos, Aros, and many other tribes inhabit the Eastern Province, and are generally of a lower grade of civilisation than the others mentioned. The country between the northern part of the Cross river and the Niger is populated by other pagan tribes, who seem to be careful cultivators, but very little is known of them at present. =Cultivation.=—The Yoruba race are industrious cultivators, and show considerably more ambition than most of the other West African peoples. The country in which they live is particularly adapted to farming, and the climatic conditions are suitable for the cultivation of cotton and fibrous plants, in addition to the various grain crops. In some parts cocoa, rubber, and kola are being cultivated, but these are not so suitable under the prevailing conditions as they would be within the wet zone—the Western Province, which these people inhabit, being entirely within the dry region. Although farming is so extensive, continuous cultivation is not found, and the use of manure is practically unknown. The usual practice is to farm a piece of land for a few years, and to permit it then to return to a wild state for a long period. In their want of knowledge concerning the value of manure and the application of artificial irrigation, the Yoruba farmers are behind the Haussas of Northern Nigeria, but are more careful than the Nupes of the same country. The depth of the Yoruba cultivation is greater than that of the northern Haussa, and this in some measure compensates for the non-employment of manure, etc.
