extraction due to the dry crushing process (varied, of course, as tho fibre in 

 the cane varies) and to use the figure so determined in the calculation of the 

 efficiency of the added water. 



Actually the amount of sugar extracted by mills falls short of that which 

 with complete admixture would be obtained with a single maceration process ; 

 the writer is of the opinion that the calculated figure for the extraction due to 

 saturation in a single maceration process might be made the basis upon which 

 the efficiency of the added water is expressed, independent of what system of 

 maceration is employed. 



TABLE f. 



Giving the density of last mill juice in a single maceration process 

 with complete admixture ; the dry crushed megass containing 45 per cent, 

 of fibre, and cane containing 12 per cent, of fibre. 



TABLE II. 



Giving, for a single maceration process, the density of mixed juice 

 and dilution per cent, on normal juice for canes containing 12 per cent, 

 fibre, dry crushed megass containing 45 per cent, fibre, and saturated 

 crushed megass 50 per cent, fibre, and normal juice containing 18 per 

 cent, of solids.
