No. 4; and 108 trees in plat No. 5. This shows the size 
of the trees fairly well and it is readily apparent that 
the last two plats, the one fertilized with nitrogen, potash 
and phosphoric acid and the one mulched, did not alone 
yield the most but the trees were also larger and in better 
condition. In regard to the mulched plat it may be well 
to remember that the material used was brought in and 
that the quantity applied probably furnished opwards 
of 1-14 pounds of nitrogen, 34 pounds potash and % pound 
phosphoric acid per tree, which is more than any of the 
other plats received. But aside from that it shows the 
value of mulching as a method of cultivation. 
In St. Lucia manuring and cultivation gives good results.* 
A field yielding 56 pounds only to begin with was brought 
up to 1,100 pounds in the short space of three years by 
pruning, forking and manuring with 1,000 pounds Basic 
Slag, 50 pounds Sulphate of Potash, 100 pounds of Sulphate 
of Ammonia and 5 cart loads of barnard manure. The 
cost of cultivation and manuring during the three years 
was $70.32 and the value of the crop for that time was 
$218.40. A gain of $148.18. ry: 
On another estate, not under the Departament supervision, 
similar cultural and manurial treatment, on 38 acres of 
old cacao resulted in a net profit of $864.00 for 9 months 
over and above the average crop reaped from the plantation 
before manuring was commenced. The benefit tae the 
general health and bearing capacity of the trees is said to 
have increased their value by $2400.00. 
From Grenada Mr. H. A. Berkely of Mount Hope Estate 
reported that in 1908. he obtained an increase of almost
