The amount of sucrose lost in the press cake was 62.9 pounds and of alcohol 43.1 

 pounds. 



Yield. 



(A) This sirup was boiled to string proof. The yield of first massecuite was 3,162 

 pounds and of first sugar 1,373, polarizing 82.4. The yield of sugar per cent masse 

 cuite was 43.4. The molasses was boiled for second sugar, yielding 1,555 pounds 

 of massecuite and 390 pounds second sugar. 



(B) The second half of the sirup was treated by the alcohol process and boiled to 

 grain. Fifty pounds sugar were added to the concentrated sirup in the pan to form 

 a nucleus. The weight of the first massecuite was 2,534 pounds and of first sugar 

 1,352 pounds. This sugar polarized 93.6. The yield of sugar per cent massecuite 

 was 53.4. The second massecuite was not ready to centrifugal at the end of the 

 season.
