The amount charged for seed cane, $10, assumes that there was only 

 a moderate loss in storage. If the cane kept very well, this amount 

 would l»e less, and if it kept very poorly, as has often happened in 

 recent years, it would be more. 



The cost of producing the first stubble crop is, of course, consid- 

 erably less, owing to the fact that all expenses for preparing the land 

 and planting are avoided, amounting in the first of the above calcu- 

 lations to $18.38. In its place, however, would come the relatively 

 small expense of " wrapping the stubble," plowing the middles, bar- 

 ring off. and raking off the stubble, amounting to about $3.50 per acre. 

 Since a poorer stand and a smaller crop are to be expected, the amount 

 of fertilizer applied is also less. This reduction may be estimated at 

 $4 an acre. The harvesting and hauling expense would be reduced 

 about $1.50. Thus the cost of the stubble crop per acre would be 

 about $53.38— ($18.38+$4+$1.50) +$3.50=$33. 



For the second-year stubble crop, with a further reduction of $2 

 in the fertilizer, harvesting, and hauling expenses, the cost would be 

 about $31 per acre. 



If we assume that $54 per acre is the cost of producing the first or 

 plant-cane crop and delivering it at the mill, and if we further as- 

 sume a yield per acre of 22 tons of cane and from it 15 barrels (equal 

 to 495 gallons) of sirup, the computed cost of producing the cane and 

 delivering it at the mill will be — 



Per ton of cane $2. 45 



Per barrel of sirup 3. 60 



Per gallon of sirup . 11 



Similarly, if we assume that $33 per acre is the cost of producing 

 the first-year stubble-cane crop, and if we further assume a yield 

 per acre of 15 tons of cane and from it 10 barrels (equal to 330 gal- 

 lons) of sirup, the computed cost of producing this crop of cane and 

 delivering it at the mill will be — 



Per ton of cane $2.20 



Per barrel of sirup 3. 30 



Per gallon of sirup . 10 



Again, assuming that the cost per acre of the second-year stubble 

 crop is $31. as above, and assuming a yield of 11 tons of cane and 

 from it 7.3 barrels (equal to 240 gallons) of sirup, the computed 

 cost of the second stubble crop delivered at the mill will be — 



Per ton of cane $2.82 



Per barrel of sirup 4.25 



per gallon of sirup .12 



The assumptions as to the cost of production and yields made in 

 the above calculations are based on good land under good manage- 

 ment. In actual practice, the yields average considerably lower with- 

 out a proportional decrease in the expense per acre. It will be noted
