Second diffusion run, December 9, 1887 Continued. 



Pounds 



Yield of first sugar per ton 128 



Yield of second sugar per ton 43 



Cane used, tons 90 



The total sugar in the cane at 90 per cent, juice was . per ton.. 226. 98 



Of these there was obtained 128 pounds at 96.G 123.6 



And 43 pounds at 87.3 37. 5 



Total pure sucrose obtained per ton.. 161. 1 



Pure sucrose left in chips do 17.8 



Pure sucrose left in molasses and lost in manufacture do 41.1 



Third sugar estimated do 17. 



Percentage sugar in cane extracted 92. 16 



The poor yield was due to use of thick chips during the first part of 

 the run, causing a loss of 1.6 per cent, sucrose in the chips. 

 Following are the analytical data of the run : 



THIRD TRIAL. 



In this run the use of carbonatation and lignite was discontinued, 

 The diffusion juices were treated with sulphur fumes until well satu 

 rated. They were then treated with lime and clarified in the usual 

 way. 



The clarification took place readily. The quantity of scums was very 

 small, and the sediment subsided rapidly, forming a thin layer on the 

 bottom of the tank, permitting the clear liquor to be easily and com- 

 pletely drawn off. The juice passed at once from the clarifiers to the 

 double effect pan and subsequently received no further purification.
