deducting the cost of the fertilizer would be 36 cents per 
tree with cacao selling at 11 cents per pound. 
In another experiment with trees 7 years old, plats con- 
taining 50 trees each, were fertilized with Muriate of 
Potash, Basic Slag and Sulphate of Ammonia with the 
following results:

These returns are not phenomenal but compared to the 
amount of fertilizer applied the increase in yield is very 
good. From an experimental standpoint the results are 
very suggestive, showing the need of Nitrogen, Phosphor-~
