SUGAR-CANE SIRUP MANUFACTURE vat 
Growers who desire to use heavy black or bottom land, or to cul- 
tivate a variety of cane that yields greater tonnage per acre and 
is more resistant to cane pests and diseases than those which produce 
sirup of the best quality, may find it best to sell their cane to a large 
steam plant. The larger steam plants may use methods of clari- 
fication which largely neutralize the tendency of poor-quality cane 
to yield a poor-quality sirup. Chemical clarification or the use of a 
refining carbon makes possible the manufacture on a large scale of a 
sirup of very uniform quality, almost regardless of the quality of the 
cane. Such sirup, however, may lack the typical juice flavor of 
sirup made by the simple boiling and skimming method. 
Larger plants operated by steam also obtain a higher extraction 
of the juice, and consequently they can make more sirup per ton of 
cane. Without corrective measures, however, higher extraction 
yields a sirup of poor quality. In the larger plants this tendency 
may be corrected by making suitable separation of juice from the

Fig. 1.—Cost, exclusive of interest and rent of land, of producing an acre of sugar cane not 
fertilized, in Louisiana in 1922 
mills (p. 39). With poor-quality cane and under certain market 
conditions, small cane farmers may find it advisable to sell their 
cane to larger mills. 
-COST OF PRODUCING CANE 
Exclusive of interest or rent of land, the 1922 cost of producing an 
acre of sugar cane in Louisiana, when using no fertilizer, is shown in 
Figure 1. As an average for all cane on a plantation, for the purpose 
of this chart, one-fourth is considered fall planted, one-fourth spring 
planted, and one-half stubble cane. 
The average cost, exclusive of rent of land, interest charges, and 
overhead supervision, for growing and harvesting for the factory an 
acre of sugar cane on plantations in Louisiana for 1922 is itemized 
in Table 4. 
In Table 4 also the cane is assumed to be one-fourth fall planted, 
one-fourth spring planted, and one-half stubble. Man labor is esti- 
mated at $1.25 a day and mule labor at $0.80 a day. At the usual
