BY-PRODUCTS OF SUGAR MANUFACTURE. 



By CLEVE. W. HINES, M. S., Station Superintendent. 



In various lines of manufacturing there are certain by-prod- 

 ucts which, years ago, constituted a waste and great loss, but 

 which now under modern methods have become in many cases 

 of considerable importance. 



This is especially true with the sugar industry. Extreme 

 care and attention is required to keep the balance on the right 

 side of the ledger, and often the proper handling of the by- 

 products forms the deciding factor between success and failure. 

 In order to build up a great sugar industry in these Islands, 

 more attention must be given to the details of the work, and 

 many of the present losses must be turned into profits before 

 great progress can be expected. 



CANE TOPS AND TRASH. 



First in the series of by-products in the manufacture of sugar, 

 comes cane tops. The amount of this material produced per 

 hectare will depend upon various factors, including the variety 

 of cane, its stage of maturity, etc. The less of these tops, 

 of course, that may be produced for a given amount of cane, 

 the better it will be for the growers, nevertheless they have 

 a good feeding value if properly handled. 



Professor Dodson, 1 director of the Louisiana Experiment 

 Station, states that he found cane tops to have the following 

 composition : 



Per cent. 



Protein 1.53 



Fat 0.41 



Carbohydrate 15.62 



Fiber 8.87 



Water 71.50 



Ash - 2.07 



The fiber content would be slightly higher and the water 

 content lower, for tropical cane, since maturity is completely
