cane in sufficient quantity to impart to the sirup a dark color and © 
inferior flavor. This tendency may be counteracted in large-scale 
manufacture by clarification with chemicals, but at the sacrifice of © 
much of the natural cane flavor. 
COST OF MAKING SIRUP 
Table 7 gives the itemized costs of materials, equipment, and labor 
required to install a sirup-making outfit suitable for grinding 10 tons 
of cane per 10-hour day and making approximately 200 gallons of © 
sirup daily. These costs vary somewhat from year to year and also © 
for different localities. —

Assuming that 10 tons of cane are ground per day and 19.4 gallons 
of sirup per ton of cane are obtained, using a 15° Brix juice, with a 60 © 
per cent extraction and an actual yield 85 per cent of the theoretical, — 
the output of sirup in this small plant would be 194 X45, or 8,730 
gallons during the 45-day season.
