From the point of view of the purchaser the great advantage of the 

 " Smooth Cay< nne" is clearly brought out from the table of propor- 

 tioual parts. 



It will be noticed that this variety contains nearly double the pro- 

 portioi! of edible fruit to that in such varieties as '' Sam CUrke" and 

 " Queen." A fruit that yields 86 per tent oF edible matter is a very 

 satisfactory one to the purchaser. 



The Ripleys, although unsurpased for flavour and density of juice, 

 yield only 55 per cent, of edible fruit, while the " Porto Rico" is 

 second to the Cayenne in this respect. 



These figures, it is submitted, put the case for the '• Smooth Ca- 

 yenne" as the commercial pine in a clear light. Under equal condi- 

 tions, this variety gives us fruits just double those of the Ripley in 

 weight and containing 60 per cent, more substance capable of being 

 eaten. 



The varieties " Sam Clarke," " Queen" and " Cheese" are obviously 

 inferior for commercial purposes. 



The chemical composition of the Pine shows as much variation 

 among varieties as the Sugar Cane. The results for the Red Ripley 

 in this series sl.ow a higher percentage of total solids and of sugars 

 than any individual case reported on by Messrs L S Munson and L. 

 M. Tolman of the IT. S Department of Agriculture, who recently pub- 

 lished the results of an exhaustive investigation on the composition ot 

 pine-apples.* At the foot of the table some of the American results are 

 given for comparison. It will be noted that the Jamaican pine-apple is 

 not surpassed by any of the fruits obtainable on the American market. 



Some of our varieties such as " Sam Clarke," " Cheese" and " Cow 

 Boy" are decidedly inferior and should only be grown faute de mieux^ 



The " Queen" and the " Ripleys" are the sweetest varieties ; nd are, for 

 local consumption, unsurpassed. For commercial purposes, however, 

 the superior eating qualities of the Ripley are more than counter- 

 balanced by the greater size, finer appearance and edible economy of the 

 " Smooth Cayenne."
