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 be 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 Avill 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
