Weight of filter-press cake pounds. . 350 



The loss of sucrose in the press cake was 24.9 pounds and of alcohol 28.8 pounds. 



Yield. 



(A) This sirup was boiled to string proof. The yield of first sugar was 1,373 

 pounds and of second sugar 408 pounds. The polarization of the first sugar was 

 82.5 and of the second sugar 83.5. 



(B) That portion of the sirup treated by the alcohol process was boiled to grain, 

 yielding 2,565 pounds of massecuite and 1,502 pounds of first sugar. The yield of 

 first sugar per cent of massecuite was 58.6. The first sugar polarized 93.8. The sec- 

 ond sugar was left in the wagons to grain, but was not ready for the centrifugal at 

 the end of the season.
