METEOROLOGY AND CLIMATE. 181 



The Victoria region, by which I understand 

 the drainage area of the Victoria Nyanza, so far 

 as that is comprised between 3,900 feet (the level 

 of the Nyanza) and 5,000 feet, falls of course 

 within the Coffee zone. , 



The Central Watershed, which includes the 

 Ankole, Karagwe and Urundi hills, and probably 

 may be held to extend along the eastern side 

 of the mountains bordering Tanganyika to the 

 east as far as the Malagarazi river, may be taken 

 as a portion of the Colony zone. 



This is simply the watershed of Tanganyika and 

 the Nile, in the wider sense of the term, and is a 

 hilly region, probably nearly everywhere well above 

 4,000 feet, and in most places OA^er 5,000 feet in 

 altitude. 



The climates of British Central Africa may be 

 roughly divided into four: 1. Tanganyika shore, 

 from 2,700 feet to 5,000 feet, which is in the 

 Coffee zone. 2. The Congo-Zambesi watershed, 

 which is in the Colony zone. 3. The Oil-palm 

 region, consisting of Lake Nyassa, the Shire and 

 Zambesi river valleys from sea level to 3,000 feet. 

 4. The Shire highlands from 3,000 feet upwards, 

 are, of course, the typical Coffee zone. In draw- 

 ing out this paper I have adopted the level 

 given by Sir John Kirk, at the Geographical 

 Congress, of 5,000 feet for the Colony zone, instead 

 of that which I have worked out myself, viz., 4,000 

 feet. Of course, taking these three regions marked
