irrespective of size, a single cane mill, giving an extrac- 

 tion of 63 0/0 juice on the weight of canes. The canes 

 themselves pass through the mill; the juice going to the 

 clarifiers on the one hand, and the megass straight to the 

 furnaces, on the other. You adopt diffusion in this 

 Fa6lory. Then you will add to your existing mill, the 

 slicing machinery and a battery capable of dealing with 

 the same quantity of canes per 24 hours as formerly, 

 and you will then obtain an extraftion of say at the very 

 least 83 per cent juice on the weight of the canes. You 

 will of course, at the same time, also have to increase 

 the capabilities of your evaporating plant and add to 

 your steam-boiler power. In the case of mills you will 

 probably have worked from 16 to 17 hours per day ; with 

 diffusion you will run continuously night and day, and 

 an electric lighting plant or its equivalent will be indis- 

 pensable in the latter case. From the increased extrac- 

 tion, apparently fully 31 per cent more than formerly 

 you will obtain fully 27 per cent more sugar from a 

 given weight of canes than you used to get through the 

 agency of mills. This difference between the extraction 

 of juice and the sugar a6lually produced will no doubt 

 greatly diminish when proper clarification has been 

 secured in connexion with diffusion juice. But it is 

 the increase of sugar obtained that must be taken into 

 the fullest consideration, for this is the figure that 

 determines the a6lual profit that will accrue from the 

 adoption of diffusion. At the same time I must remind 

 you that with careful work it is quite possible to obtain 

 an extraction of 85 per cent juice on the weight of canes 

 with the new process. By the time the diffusion juice is 

 in the clarifiers, and the exhausted slices ready for firing on
