The refiners discriminate against sorghum sugar as manufactured by 

 the ordinary process, and pay per degree of polarization a smaller price 

 for the sorghum than for the cane product. 



The objection of the refiners to sorghum sugar as manufactured by 

 the ordinary process can not exist with that obtained by the alcohol 

 process, since in the latter the objectionable gums are removed. 



For the sake of a comparison of the two sugars, in the calculations 

 given below, no account is taken of this discrimination. The prices 

 are based on the New York quotations as published in the Louisiana 

 Planter and Sugar Manufacturer, issue of March 5, 1892. The deduc- 

 tion per one-tenth degree per 100 pounds of sugar is taken at one-six- 

 teenth cent. 



Value of sugars on a refining basis. 



A. Price of "fair refining," 89 test, $3 per 100 pounds. 



89.0= test of market. 



84. 7= average test of first sugar made, ordinary process. 



4.3:= difference in test. 

 1 .'.43 X iV =$0.027, deduction per 100 pounds sugar on account of lower 



polarization. 



$3.000 0.027 =$2. 973, net price of sugar, per 100 pounds. 

 Sucrose value =$3.51 per 100 pounds. 



B. Price of " centrifugals " 96 test, $3.406 per 100 pounds. 



96.0= test of market. 



92.6= average test of first sugar, alcohol process. 



3. 4 = difference in test. 

 ,\ 34xA'=$0.021, deduction per 100 pounds sugar on account of lower 



polarization. 



$3. 406 -0.021 =$3.385, net price of the sugar per 100 pounds. 

 Sucrose value = $3. 655 per 100 pounds. 



From the above calculation it may be seen that the planter would 

 receive $0.145 per 100 pounds sucrose in his first sugar more money if 

 he employs the alcohol instead of the ordinary process. In addition to 

 this he is enabled to place his product on the market promptly, and to 

 sell a sugar which can compete under favorable conditions with that 

 manufactured from cane. This is a decided gain over the methods now 

 in use. 



In these calculations no account is taken of the bounty on sugars. 

 The unwashed sorghum sugars by the ordinary process would prob- 

 ably polarize below 90 and receive the lower rate of bounty. Grain 

 sugars by the alcohol process will polarize above 90 as a rule and 

 receive the higher rate of bounty. 



Sirups bleached with sulphurous acid and then treated by the alcohol 

 method will yield an excellent grade of yellow clarified sugar. 



Further experiments are necessary to determine to what extent the 

 increased fuel consumption and the loss of sugar in the filter-press 

 cake would offset the gains by the alcohol method.
