CRYSTALLIZATION 79 



with that contained in each product going out ; thus 

 the profit on each class of sugar produced can be defined 

 and compared to a nicety a very valuable bit of 

 information. The syrup at each stage of the operations 

 should also be examined in order to ensure uniformity 

 of work. Coal and charcoal must be watched in the 

 same way, and so must scums, charcoal washings and 

 such-like matters. In a cane sugar factory all this 

 must be done, but it is much more difficult. An accurate 

 knowledge of how much sugar enters in the form of 

 cane is almost impossible. Even to weigh the cane 

 accurately is an arduous task ; and even then it varies 

 in quality so constantly from day to day that any 

 estimate can, at the best, be only approximate. Never- 

 theless it is done, and very fair figures are given, in 

 good factories, of sugar coming in, going out, and lost. 

 Cane, megass, juice, masse-cuite, syrups, molasses, 

 waste waters and finished sugars are all weighed or 

 measured, and analysed. The beetroot factories were 

 the first to show the necessity for all these things, and 

 the best way to do them. Cane sugar has learned the 

 lesson, and so have the sugar refiners.
