The loss of sucrose in the filter-press cake was 40.9 pounds (4.7 pounds per ton

Yield. 



In this and the rest of the experiments, the alcohol process only was employed. 

 The work by the ordinary process required so many sugar wagons and occasioned 

 so much delay with the niassecuites that it became necessary to abandon the plan of 

 carrying on parallel experiments. 



The sirup was boiled to grain and yielded 1,875 pounds of first massecuite and 965 

 pounds of first sugar, the latter polarizing 92.5. The yield of sugar per cent 

 massecuite was 51.5. 



Sugar to the amount of 50 pounds was added as usual to the sirup in the pan. 



The second massecuite was left in the hot room, as it was not ready for the centrif- 

 ugal at the end of the season.

The McLean cane yielded a very rich juice, containing a low percentage of glucose. 

 The loss of sugar after the concentration of the juice to sirup was very large and 

 materially decreased the yield.
