THE EXTRACTION OF JUICE BY MILLS. 



On examining the tables and curves it is at once apparent that the main 

 factor in determining the economy is the relative value of sugar and coal; any 

 variation from the ratio adopted here entirely alters the conditions, and an 

 unfavourable alteration might easily, in the case of a poor cane and two mills, 

 convert the estimated profits into a loss. The second point to be noticed is that 

 whatever the admixture, the expenses of evaporation remain the same ; a lower 

 coefficient than that adopted here would also in many cases, indicate a loss. 

 Thirdly, the great financial profit due to a third mill is clearly shown. 



CANES 13-69 PER CENT. SUGAR. THREE MILLS. 



CANES 13-69 PER CENT. SUGAR. Two MILLS. 



Tons added Water per 100 tons of Cane. 



CANES 10-26 PER CENT. SUGAR. THREE MILLS. 



Tons added Water pen- 100 tons of Cane.
