Yield. 



The yield of first massecuite was 2,426 pounds and of first sugar 1,138 pounds, 

 polarizing 92.1. Forty pounds of sugar were added to form a nucleus upon which to 

 build grain, but nevertheless the massecuite was sticky, and it was necessary to keep 

 it in the hot room some time for the sugar to separate. The yield of first sugar per 

 cent massecuite was 46.9. 



The molasses from the above was boiled for second sugar and yielded 205 pounds, 

 polarizing 87.8. 



The analytical data indicated that the India and orange cane was of excellent 

 quality; hence it is probable that the vacuum-pan work is responsible for the diffi- 

 culty in drying the sugar. A small pan is very sensitive to slight changes in the 

 vacuum or to other irregularities, and even a good panraan may fail to obtain a good 

 result.
