The loss of both sucrose and alcohol in the press cake was large. In experiments 

 Nos. 10 and 12 there was not sufficient material to completely fill the filter press, 

 hence the press-cake was soft and the loss of sugar and alcohol large. In experi- 

 mental work of this class the filter press should be so constructed that either all or 

 a part of the press can be used. 



The loss of sucrose in the filter press cake amounted to 56.7 pounds and of alcohol 

 37.8 pounds. 



Yield. 



The sirup was boiled to grain. Fifty pounds sugar were added to form a nucleus 

 upon which to build grain. 



The yield of first massecuite was 2,193 pounds, and of first sugar 1,045 pounds. 

 The yield of first sugar per cent massecuite was 47.7. The sugar polarized 91.4. 



The first massecuite was boiled too stiif and dried slowly in the centrifugal. 



The molasses from the above was boiled for second sugar and yielded 255 pounds, 

 polarizing 84.1.
