Comparison of canes grown in Jamaica with the same varieties grown 



in Demerara. 



Weight of Chop per Acre. 

 Rather smaller, ... Elephant. 



About equal, ... Otaheite, Caledonian Queen, Java, Hope, Red 



Rose Ribbon and Hillii. 

 About double, ... Salangore, Green Rose Ribbon and Brisbane. 



About three times, . . . China and Po-a-ole. 

 About five times, ... Ko-poa-pa. 



Proportion of Juice. 



Is about equal or slightly larger than that yielded by the same variety 

 in Demerara. 



Proportion of Sucrose in the Juice. 



.. Lahaina, Ko-poa-pa, Elephant, Green Rose Ribbon, Bris- 

 bane and Po-a-ole, (Second Ratoons.) 

 .. Po-a-ole, (Plant Canes.) 



. . Otaheite, China, Salangore, Caledonian Queen, Java, Hope, 

 Red Rose Ribbon. Green Rose Ribbon, Brisbane, Grand 

 Savanne, Hillii, Bouranappa. 



Quotient of Purity. 

 Follows much the same order as the proportion of Sucrose. 



Yield of sugar per acre supposing 85 per cent, of the Sucrose in 



the Juice is won. 



This is smaller from the Elephant Canes but larger from all the 

 others as might be expected from the superiority in weight of crop per 

 acre. 



I suspect that the six canes which proved inferior in proportion of 

 sucrose and purity were not really ripe. 



Numbered Canes. 



These Canes compare more irregularly than do the named canes, as 

 will be seen from a glance at the table appended. 



On tbis table I would remark that Nos. 95 and 119 are very little 

 below the Demerara grown canes of the same numbers, in contents of 

 sucrose ; while I suspect that the other canes which yielded less sucrose 

 were not fully ripe. 



In conclusion I would repeat that one j^ear's results are not sufficient 

 to allow a decided opinion to be formed and that these experiments 

 need to be repeated before it will be possible to determine the fitness or 

 otherwise of these canes for cultivation in Jamaica.
