are usually drawn from the cell at too high a temperature to admit of 

 its use without great danger of inversion. With mill juices even, 

 when sulphur is used, great care and celerity should always be exer- 

 cised. Separate the sulphured juice at once, evaporate the juice to 

 sirup immediately after defecation and from the sirup concentrate to 

 massecuite without stopping, and so on as fast as the lower grades will 

 allow of good results. This, however, is true of any sugar-house, whether 

 sulphur is used or not, and large losses, which are often attributed to 

 some method of manufacture, are due to nothing else but delay in work- 

 ing up the juice after it has been soured. Certainly Calumet, with th e 

 highest average season's yield ever reported in Louisiana, and this with 

 an extraction of from 80 to 87 per cent of sucrose present in the cane, 

 has no reason for changing its treatment of the juice as long, at least, 

 as it continues mill-work. Cheapness and effectiveness are two as good 

 recommendations as anything needs, and both of these can be applied 

 to the use of sulphur at Calumet. 



MACERATION AND ITS EFFECT ON YIELD. 



Below is given a table showing the work done both before and after 

 maceration was begun: 



The addition of water was begun about the middle of the first plant- 

 run, and as it was thought unnecessary to divide the run, the actual 

 yield of merchantable sugar can not be given exactly, but since abound
