The data for the flower production during 1905, on the same 



trees is now given for comparison with previous years. 



MONTHLY FLOWER PERIODICITY, I905. 



NUMBER OF COCOA FLOWERS ON ESTATES. 



These observations prove that there is not a month in the year 

 when flowers are not produced if a minimum of say ten trees is 

 chosen. On six out of the forty-two trees selected no flowers were 

 produced during certain months of 1903, these months including 

 only February, March, and April. 



The total amount of flowers produced on a cocoa estate may be 

 from 1,700,000 to 3,606,000 per acre, per year (300 trees to the 

 acre). A yield of 3 cwt. of cured cocoa per acre means that at the 

 most only about 8,000 flowers develop into mature fruits on each 

 acre per year, or, in other words, a balance of 1,692,000 to nearly 

 3,600,000 flowers, per acre, per year, are at present of no value to 

 the average cocoa planter. A large number of flowers appear to 

 have been fertilised, but the expanding fruits soon turn yellow and 

 shrivel ; for the year 1903 out of a total of 569,738 promising fruits, 

 no less than 288,205 were of this class. 



These facts show that there is ample opportunity for research in 

 connection with flower pollination and fertilisation. The cocoa 

 trees on which the these observations were carried out were 

 normal ; it would have been possible to select much more vigorous
