native food crops. Cadbury Hall at Kumasi was intended to be 

 an agricultural college for training Africans for the agricultural 

 service; activities were much reduced in the depression years and 

 at present its training functions are limited to courses for foresters. 

 Some research is in progress there and on the experimental farm 

 attached. The Hunter Hostel is used for two months training for 

 African farmers. There is a botanical garden at Aburi near Accra 

 of about fifty acres on which investigations are carried out with 

 local crops and ornamental plants. It is planned to begin trials 

 with tea there also. In addition, three local stations are maintained 

 for rice, coco-nut, and shea trees respectively. 



The organization of co-operative societies in the cocoa industry 

 is a special function of the agricultural department. In addition 

 to annual reports, a series of agricultural bulletins has been pub- 

 lished since 1925, containing results of research and departmental 

 activities. Included in the bulletins are year books for 1926-30, 

 each containing many papers on scientific aspects of agriculture, 

 but since 1 930 the publication of year books has had to be sus- 

 pended. The Gold Coast Farmer, a journal designed to inform the 

 general public on results of research, has appeared monthly since 

 May 1932. 



The Department of Animal Health has its centre at Pong- 

 Tamale in the dry Northern Territories, where there is a labora- 

 tory devoted partly to serum production, the most recent of the 

 African veterinary laboratories to be established, and a large stock 

 farm where research is undertaken on animal breeding and nutri- 

 tion. The tsetse fly problem has also been subject to experiment at 

 Pong-Tamale as mentioned in Chapter X. One of the veterinary 

 officers is stationed in the Accra Plains, a region of low rainfall 

 near the coast, where opportunities are offered for a considerable 

 stock industry. Annual reports are the only regular official publi- 

 cations of the department. 



In Sierra Leone the Agricultural Department is centred at the 

 Njala Laboratories. There are three experimental farms. That at 

 Njala is for general research work, including the improvement (by 

 selection) of upland rice, the investigation of maintenance of fer- 

 tility, the selection and breeding of oil-palms, and other investiga- 

 tions with citrus, coffee, kola, pepper, etc. At Rokupr there is a
