THURSDAY, JUNE 25.-AFTERNOON SESSION, 
2.30 P.M. 
Section I,—Rubber. 
Chairman: Sir Epwarp Ros inc, Chairman-elect of the 
Ceylon Association in London. 
THE CHAIRMAN : Gentlemen—We have a great deal of work 
to get through this afternoon, and I think you all realize that 
in order to get through it we shall have to limit the papers to 
a certain length of time—a quarter of an hour—and the contri- 
butions to the subsequent discussions to five minutes. I will 
first call upon Mr. Simpson, the Director of Agriculture of 
Uganda, to read a paper on Hevea brasiliensis in Uganda. 
THE CULTIVATION OF HEVEA BRASILIENSIS IN 
UGANDA. 
By Samuet Simpson, B.Sc., 
Director of Agriculture, Uganda. 
[ABSTRACT. ] 
This rubber tree is the one being most largely planted in 
Uganda at the present time, and coffee is planted as a catch- 
crop generally. , 
The tree grows well in height, but slowly in thickness, for 
two or three years, but then thickens fairly rapidly, and at five 
years old a girth measurement of 16 in. is fairly common; 
such trees can be lightly tapped. 
The oldest trees in the country are in the Botanical Gardens,
