SUGAR-CANE CULTURE FOR SIRUP PRODUCTION. 39 
that under the above assumptions the first-year stubble crop is pro- 
duced more economically and the second-year stubble crop less eco- 
nomically per unit of the product than the plant-cane crop. 
COST OF MANUFACTURING THE SIRUP. 
Without going into details in this bulletin with respect to the 
manufacture of sirup, it must suffice here to give merely a summary 
of the manufacturing expenses, under two sets of conditions, viz : 
(1) With the small farm outfit, which includes a mill driven by a 
gasoline or kerosene engine and an evaporator of the Cook type ; and 
(2) with the larger steam outfit, suitable for large farms. With the 
smaller of these two outfits, costing, as indicated under " Equipment 
and capital invested" (p. 34), about $600, the annual allowance for 
interest on investment, repairs, and deterioration should be about 
22 per cent of the original cost. With the larger or steam outfit, 
assumed to cost $5,000, about IT per cent should be allowed. 
With the smaller outfit a capacity of about 6 barrels of sirup per 
day of 12 hours may be assumed. Assuming a grinding period of 
24 days each year, the amount chargeable to each day of operat- 
ing for interest on investment, repairs, and deterioration will be 
$600X0.22-^24, or $5.50. To operate such an outfit, putting the 
sirup into barrels, not cans, a crew of four men is required, with 
wages totaling about $4 a day. 
Summarizing these and other items, the estimated cost per day to 
operate this plant will be as follows : 
Interest on investment, repairs, and deterioration $5. 50 
Wages of crew of 4 men_. 4. 00 
Gasoline, 9 gallons at 20 cents 1. 80 
Fuel (good-quality wood) for boiling, 2 cords at $1.50 3.00 
Six empty barrels at $1.25 7. 50 
Total manufacturing expense: 
Per day, producing 6 barrels of sirup 21. 80 
Per barrel _..____■ 3.63 
Per gallon _ . 11 
With the large steam outfit, assumed to cost $5,000 and to have 
a capacity of 40 barrels a day, running 24 hours a day on a double 
shift, with a crew of 8 men on each shift operating 24 days in the 
year, the daily expenses would be about as follows: 
Interest on investment, repairs, and deterioration ($5,000 
X 0.17-24) $35.42 
Wages of two crews of 8 men each _ 22.00 
Fuel (second-quality wood, but a long haul), 15 cords, at 
$1.50_ 22. 50 
Forty empty barrels at $1.25 50. 00 
Total manufacturing expense : 
Per day, producing 40 barrels of sirup L 129. 92 
Per barrel 3.25
