Table No. 2 

 Weight of 500 Frtjits. and Beans fbom these at Vaeiotjs Stages 



From Table No. 2 it will be seen that the weight of 

 cured beans from 100 fruits varies from 7" 5 lb. with 

 Caracas to 9' 8 lb. from Forastero, the average from the 

 three kinds which are present in varying numbers on all 

 the plots being 8" 451b. 



Taking the sulphate of ammonia, Plot No. Ill, with a 

 yield of 11,070 fruits, the weight of dry cocoa per acre 

 would be 8J cwt., which is very high, whilst the cost of 

 the manure is only 23' 12 Rs. (£1 10s. lOd.) per acre per 

 annum. 



The yield from the unmanured plots is equivalent to 

 4| cwt. of dry cocoa per acre. 



It is difficult to understand the extraordinary manner 

 in which the yields of specific plots have fluctuated from 

 year to year. In drawing comparisons between the 

 yields of different plots the reader is recommended to 

 bear in mind that the 1907 annual report on these ex- 

 periments states : " Although the results of the manure 

 experiments are recognised to have amply justified their 

 existence in every case, yet at the same time it is felt 

 that the plots are not of a representative and uniform 

 character, because the trees were originally planted
