By means of filter presses designed especially for the purpose this 

 loss of sugar can be reduced to a very small amount. Improvements in 

 the distilling process would materially diminish the dilution of the 

 sirups and the consequent increased fuel consumption. The increase 

 in fuel consumption can probably be reduced to but little more than 

 that required in the recovery of the alcohol. 



EXPERIMENTS IN THE TREATMENT OF MOLASSES. 



Two sets of experiments were made in the treatment of molasses from 

 other sugar houses. 



In these experiments the molasses was diluted to 54 Brix and then 

 treated with an equal volume of 90 per cent alcohol. The alcohol-mo- 

 lasses mixture was filter pressed and the alcohol recovered by distilla- 

 tion. 



Unfortunately, in the case of the molasses from the Medicine Lodge 

 factory, the analytical data are incomplete, hence the losses can only be 

 traced indirectly. 



MOLASSES FROM FACTORY OF MEDICINE LODGE SUGAR COMPANY. 



This molasses was obtained October 6 directly from the centrifugals, 

 which at the time were drying first sugar.

Yield. 



The purified molasses was boiled to string proof and yielded 2,083 

 pounds of massecuite and 888 pounds of sugar polarizing 80. The 

 yield of sugar per cent massecuite was 42.6.
