and applying these figures to the formula, leaving « unknown 
we get x=9. This means that it may take 9 more than 10 
tons, or 19 tons, of cane per ton of sugar, without reducing the 
net profit—namely 40 per cent. 
For different net proceeds ranging from 80 pesos to 220 pesos, 
Table 1 shows the amount of cane (in tons) that mills of various 
capacities may require in order to make the stipulated profit. 
The capacities range from 150 to 600 tons per day.

For a factory working at full capacity the rendement allow- 
able depends upon the net proceeds from the sugar. However, 
there is the possibility that a factory cannot be run continually 
at full capacity, owing to various causes; such as a breakdown 
in the mill, rains, lack of labor, transportation difficulties, and 
fires. If for any of these reasons the capacity is cut in half, 
by again using the formula but now adopting 300 tons as ca-
