Hill-tops or upper slopes often support only a 

 low vegetation of fine grasses and small herbs. 

 This is generally due to the shallowness of the 

 soil which covers the underlying rock. 



Temperature and Rainfall. The temperature 

 of the country, although it is on the Equator, is- 

 never extreme. The heat is tempered by the great 

 elevation, by an almost continuous light breeze, 

 and by the existence in the neighbourhood of such

 The mean maximum temperature is 80 F., the 

 mean minimum 62 F. There is little variation

 at night. The relative humidity is high. The
