growth and yield. Unfortunately the first tree 

 introduced was blown down in 1910, so that its 

 record of growth and yield, which might have 

 extended our knowledge three years further, is of 

 no service. 



From reports published by the Botanical and 

 Forestry Department, we are able to obtain the 

 following figures relative to the trees just referred 

 to: 



These figures show that the tappable size, i.e. y 

 16 inches girth at 3 feet from the ground, is 

 reached in five years from the time of sowing ia 

 Uganda. This is further borne out by an ex- 

 amination of the results obtained in fairly exten- 

 sive plantations on the Kivuvu estate; and results 

 given in a later chapter prove that tapping at five 

 years is quite a success commercially, and in no 

 way injures the trees if properly carried out.
