TAP.I.I-: No. 1(5. Juices front d((J'itniou chijm Contiiuird. 



The analyses of the samples of chips taken from each charge of the 

 battery, often twice daily, show the remarkable fluctuations in sucrose 

 which have always been noticed in sorghum juices. 



The mean composition of the normal juice, Table 10, shows a less per- 

 centage of sucrose, but a somewhat higher purity than were obtained 

 at Fort Scott. 



The maximum percentage of sugar in the juice is not as great as at 

 Fort Scott, and the minimum is not so small. In general it may be 

 said that the canes worked at Eio Grande were slightly inferior for 

 production of sugar to those of Fort Scott. 



The theoretical yield per ton, based on the Fort Scott analyses, 

 would have been as follows : 



Pouuds of juice at 93 percent, extraction 1,074. 



Glucose x 1.42 4.60 



Sucrose less glucose x 1. 44 4. 38 



Pure sucrose, first crystallization 7:5. 32 



Pure sucrose, etc., at Fort Scott 78. 8 



The yield obtained, for various reasons, was much less than this. 



The tonnage obtained at Kio Grande, however, was fully double that 

 at Fort Scott, and this heavy growth may account for the slightly in- 

 ferior quality of the cane.
