[DISCUSSION.] 



M. BRENIER (Indo-China) : I have been much interested in 

 Mr. Barrett's contribution, because I am very keenly interested 

 in a country just opposite the Philippine Islands, that is to say, 

 Indo-China. If I understood rightly, Mr. Barrett attaches 

 extreme importance to the sugar palm, which he considers will 

 come to the fore in a very short time. I should like to ask 

 whether he really considers it as being a possible competitor 

 against the sugar qane. What do you consider, Mr. Barrett, 

 would be the comparative yield per acre of the sugar palm and 

 the sugar cane ? 



Mr. BARRETT : That is a difficult question to answer. 

 When we come to statistics of yields per acre we always 

 are rather cautious, but in the article on the subject in 

 the May number of the Philippine Agricultural Review some 

 estimates are given. Not having those figures at hand, I can 

 only say that we calculate the yield per acre from the sugar 

 palm to be about twice the present yield of sugar per acre from 

 sugar cane with the ordinary cultivation. Taking the general 

 average of the yield from sugar cane, I think I am warranted in 

 saying that the sugar palm is giving a better yield of sugar 

 from its much richer sap than the sugar cane, and without any 

 expensive machinery. I know it is a very strong thing to say, 

 but it is certainly going to be a very dangerous rival to the 

 sugar cane when handled by modern methods.
