AVERAGE RESULTS OF ANALYSES OF SORGHUM, ETC. 213 



^aveu iu the last three columns will show what amounts of stripped 

 stalks, juice, and available sugar, can be obtained on an acre from each 

 variety of sorghum. The number of stalks per acre has been placed at 

 24,000, which is believed to be a fair estimate. 



In comparing these figures with those in the three columns just pre- 

 ceding them, which represent actual results of analyses, it will be seen 

 that the figures do not difler greatly. 



6. After all, the real test of value for any caue, is the amount of 

 crystallizable sugar that can be actually separated from the juice ob- 

 tained from tlie stalks grown on an acre. This amount will depend 

 very greatly on the quantity and quality of the canes, and upon the 

 promptness aud cai'e with which they are worked up after cutting. The 

 figures here given in explanation of the various points which have 

 been discussed, have been derived frcmi very carefully conducted work, 

 and they are offered as fair statements of what can and should be at- 

 tained by careful workers. 



Among the essential points worthy of repetition are the following : 



1. Select a cane that matures quickly, aud has as long a working 

 period as possible. 



2. Do not work the cane too early ; the seed should be well matured 

 and quite hard, and tlie juice should liave a specific gravity of 1.0G6 or 

 higher. 



3. After cutting the canes, work them up without great delay. It 

 is best to draw directly from the field to the mill as may be needed.
