The chief agricultural products of the Cameroons are rubber, palm kernels, cocoa and palm oil, and the Protectorate may be said, in a general way, to present three chief agricultural areas: the southern, with rubber in increasing production; the middle province around the Cameroon river basin, with their plantations and areas rich in oil palms; and the grass country, northward, suited specially for cattle breeding. Nearly all the rubber exploited has been derived from the native exploitation of wild plants. Almost all the male population of Lomie, Molondu, Dume, and Dengdeng was concerned in rubber collection in 1910-11, in which years more than 1,000 coloured middlemen bought the rubber from the natives and sold it to the forty-nine mercantile firms who had no fewer than 230 stations established for its purchase. The comparatively small share of rubber plantations in the whole production of the Protectorate is shown by the fact that, of a total export of 5,957,516 lbs. in 1911, all except 23,912 lbs. was from wild plants; whilst in 1912 cultivated plants accounted for only 53,040 lbs. in a total shipment of 6,184,222 lbs. The results of the attempts to induce the natives to take up new cultivations depend on the presence or absence in their district of wild plants that they can exploit. Whilst, for example, the inhabitants of the Lomie district, who still know of rich stands of wild rubber plants, are hardly to be excited to commence rubber cultivation, it has been experienced in Kribi, where these do not exist, that the distribution of young plants are gratefully received and readily planted.
