SUGAR-CANE CULTURE FOR SIRtXP 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 17 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 



Sis empty barrels at $1.25 7. 50 



Total manufacturing expense: 



Per day, producing G barrels of sirup 21. SO 



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 



XO.17-^-24) $35.42 



Wages of two crews of S 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 129. 92 



Per barrel 3.25 



Per gallon . 10
