tivation are studied at Yoroberi-Kunda, and breeding at the Wuli 

 experimental station. In Sierra Leone efforts are being made to 

 increase production, since crops are not sufficient to meet the 

 requirements of the local food market. In Eastern Africa there are 

 many areas suitable for groundnuts, and a considerable production 

 exists mainly for local consumption. In Tanganyika, however, 

 exports in 1936 amounted to 23,000 tons out of a total of 38,000 

 tons marketed. Selection work is in progress in all the British 

 territories. 



Senegal has the greatest groundnut export of any country in 

 Africa, and experience there is significant in view of the increasing 

 interest in this crop elsewhere. In this territory rainfall diminishes 

 with latitude north of the equator, from 50 inches per annum south 

 of the Gambia to i o inches on the Senegal River. The whole 

 country can accordingly be divided into three regions for the pur- 

 pose of cultivation, namely the dry region in the north, the middle 

 region east of Dakar, and the wet region surrounding the Gambia 

 River. The dry region in the north was formerly the most produc- 

 tive, and the Rufisque groundnuts exported from the port of that 

 name were once all grown there. Now, however, the soil in the 

 northern region has been seriously impoverished, and the central 

 belt is at present the most productive. Since continuous cropping 

 without a rotation would lead there also to infertility, great impor- 

 tance is attached to experiments with manures. The crop depends 

 largely on the length of the rainy season, and the limit of production 

 depending on rainfall seems now to have been reached. In the 

 extreme north of the territory, along the Senegal River, small 

 inundation canals have been constructed in a number of places 

 to control the flood waters for groundnut cultivation, and in other 

 dry areas it is proposed to construct irrigation wells. 



The agricultural experimental station at M'Bambey, not far 

 from Dakar, has been established for some ten years, and much 

 work has been done, some results of which have been published 

 by Rambert (1928) and Sagot (1935 and 1937). In addition to 

 the selection of local strains, other varieties of groundnut have been 

 introduced from India, America, and Natal, with the result that 

 several types of groundnut are now considered to be perfectly 

 adapted to each of the three principal regions of Senegal. Seed is
