The planting is not done sufficiently carefully, the cocoa 
trees being often planted with a part of the stem in the earth. 
(4) Shade is necessary during the first three or four years. 
The plantain or banana is well suited for this purpose; also, 
at the beginning, pigeon pea. 
Permanent shade may not be indispensable, but it is very 
useful and profitable in a dry-season climate such as that of 
Mayumbe. 
Forest shade trees should not be kept; it is much better to 
use artificial shade which can be better regulated. 
Mixed planting of cocoa trees with palm or coconut trees is 
recommended. 
Diseases and insects are now being studied by Government 
specialists. In the case of Salberghella good results have been 
obtained by getting native children to catch the insects by 
hand. 
NOTES ON SOME EXPERIMENTAL RESULTS IN CACAO 
CULTIVATION. 
By Professor P. Carmopy, 
Director of Agriculture, Trinidad. 
[ ABSTRACT. | 
This paper gives a preliminary account of some of the 
experiments in progress under the supervision of the Depart- 
ment of Agriculture in Trinidad, on various problems con- 
nected with the cultivation of cacao. The results are sum- 
marized in a series of tables. Eight of these tables deal with 
the natural yield of dry cacao per tree, one with the weight of 
dry cacao produced per pod, and one records analyses of cacao 
soils taken from adjacent plots in a field under experiment for 
natural yield. The interest of the paper lies mainly in the 
details given in these tables, which will be reproduced when the 
paper is printed. 
A short account is also given of the system of agricultural 
education in Trinidad and of the means adopted by the 
Agricultural Department for distributing information on 
agricultural subjects, and stimulating interest in agriculture 
among the peasants.
