marketing, entomology, plant pathology, meteorology and 

 chemistry. The European staff of the three departments num- 

 bers 257, of whom twenty-five are specialist officers engaged in 

 administrative or research duties. Research stations are main- 

 tained as follows: two stations, each of about one hundred acres 

 in area, in close proximity to Salisbury. On one, known as the 

 Salisbury Experimental Station, the chemical, entomological, and 

 plant pathological laboratories of the department are situated. 

 This station concentrates on experimental work with grain and 

 legume crops, potatoes, and pasture grasses, and on manurial, 

 fertilizer, and green manuring experiments, and new crop intro- 

 ductions. The second, the Hillside Station, is devoted to plant 

 breeding, mainly with wheat, and to trypanosomiasis research. 

 Sixty miles north of Salisbury is the Trelawny Tobacco Research 

 Station of 500 acres, with a research staff of eight, including a plant 

 breeder, a chemist, a biologist, a plant pathologist, and a physiolo- 

 gist. Stations concentrating on pasture research are situated at 

 Matopo, Marandellas, and Rusape, the first-named forming part 

 of the Rhodes Matopo Estate and Experiment Farm, some twenty- 

 seven miles from Bulawayo. The experiment farm is mainly con- 

 cerned with problems of cattle and pig breeding and animal 

 nutrition, and crop production under Matabeleland conditions. 

 The British South Africa Company maintains the Mazoe Citrus 

 Research Station (60 acres), with a staff of six specialists. The 

 Southern Rhodesia Agricultural Journal, published monthly, records 

 the investigational work and other activities of the department 

 and has, besides that within the colony, a considerable circulation 

 amongst farmers in adjoining territories. In addition a large num- 

 ber of departmental bulletins have been published, and the annual 

 report of the department of agriculture and lands, as presented to 

 the Legislative Assembly, is published each year in March or April. 

 The Anglo-Egyptian Sudan, though not strictly within the scope 

 of this study, is important for comparison. Its present large agri- 

 cultural organization was formerly divided into two: the Depart- 

 ment of Agriculture and Forests, with headquarters at Khartoum, 

 and the Agricultural Research Service centred at the Medani 

 Laboratory. These two branches were combined in 1935. The 

 research service has two experimental stations: the Gezira re-
