360 THURLOW AND PRATT. 
The conditions of manufacture were such as to make the ex- 
traction low and the losses high. The cane was long overripe 
so that it contained considerable invert sugar, and the working 
crew was new and inexperienced, making overheating of the 
juice and other wasteful practises common occurrences. The 
mill operated under less than full capacity with no attempt to 
crush at night, and a comparatively small amount of sugar was 
introduced, as the quantity of cane crushed during the run 
amounted to only 113,840 kilograms.? 
Facilities for weighing both the cane and the juice were not 
available, so that the quantity of sugar introduced was deter-.- 
mined volumetrically; that is, by measuring the hot juice in the 
settling tanks or subsiders, correcting this volume for tempera- 
ture, and ascertaining the percentage of sucrose. The results 
obtained are recorded in Table I.
