The Citrus beds contain all the best kinds of oranges, Tanger- 
ines, Grape Fruits, Shaddocks, Pomelows, Lemons and Limes. 
Several kinds of Coffee are grown, the two principal Vanillas, 
Cola nuts, most of the recognized rubber trees including the 
Landolphias, Nutmegs, Cinnamon, Camphor, Mangoes, Mango- 
steens, Durians, and other trees and plants of medicinal or other 
use tO Man. _— 
Cocoa covers about 74 acres of ground and is planted in } acre 
plots, each of which receives different treatment in the two series 
of manurial experiments started in the years 1900 and 1907 
respectively. Some of the plots occupy flat land, whilst the 
others are situated on the Morne Bruce slope. 
This slope is typical of the rugged character of the land on 
planter’s estates in different parts of the island, and on this 
account was selected for some of the plots to ascertain the manu- 
rial requirements of cocoa growing elsewhere in similar situations ; 
as well as for comparing the results with those obtained from 
the plots on level ground. 
To skim over things, as one must needs do in a paper of this 
kind, scarcely does justice to such an important part of agricul- 
€ as manurial experiments prove to be. It may, however, 
suffice to mention here that the experiments have been splendidly 
conducted and records carefully kept. At the time of writing

Apart from the interesting results, these experiments have 
the additional merit of being the only ones of their kind conducted 
over such a long period of years. 
It may be interesting to mention under this head that the 
crops from the cocoa plots, lime experiment plots, together with 
miscellaneous fruits and spices from other economic plants in the 
collection are a source of considerable financial support to the 
Department.
