METEOROLOGY AND CLIMATE. 179 



results always in the breakage of anything break- 

 able. 



My instruments were lent by the Royal Geo- 

 graphical Society, and consisted of two boiling- 

 point thermometers, a maximum, minimum and 

 wet and dry bulb thermometers, prismatic compass 

 and plane table. 



I tried to take daily observations of temperature 

 at 2 p.m., when usually in camp, and at 7 p.m., 

 before packing up for the night. As regards 

 climate, British Central Africa and East Africa 

 may be roughly divided into four main divisions : 

 1. The Cocoanut or Oil-palm zone, which is below 

 3,000 feet. 2. The Coffee zone, which lies be- 

 tween 3,000 and 5,000 feet. 3. The Colony zone, 

 between 5,000 and 7,000 feet. 4. The Cloud-belt, 

 above 7,000 feet. 



In our East African sphere the first division 

 breaks down, however, for it includes two very 

 different climates. The first is that part of the 

 coast immediately bordering the sea, which is 

 below 1,000 feet in altitude. Most of the large 

 rivers carry the physical conditions characteristic 

 of it for a long distance inland, so that its outline 

 is very irregular. In a natural state it is a dense 

 tropical jungle, with the Rubber vine and many 

 creepers. 



The second is the remaining portion of the 

 eastern coast, below 3,000 feet in altitude. This 

 is covered naturally by Euphorbia trees, Acacias,
