produce to ship-board, to set against the increased 

 quantity of sugar. 



We may, perhaps, add the loss which might arise 

 from an increased liability to stoppages arising from 

 mishaps. Any such stoppages are as a rule costly both 

 in labour and fuel. It is, however, too soon to calculate 

 the value to be attached to this. The difficulties attend- 

 ing the starting of a new process and getting the hands 

 well acquainted with the work required of them, are 

 always considerable, and it would not be fair to assume 

 that because stoppages of various kinds have frequently 

 arisen in fa6lories where diffusion has been tried, 

 they may not with more experience be got rid 

 of altogether. 



If we take the case of a fa6lory making 2,000 tons of 

 all sugars at present with double crushing, it seems 

 possible to estimate roughly what the value of the in- 

 creased sugar would be, and what would be the cost 

 of obtaining it. 



We have already stated that it is claimed that the 

 diffusion juice obtained from the cane is equivalent to 

 an extraftion of 85 per cent, of original juice. It may, 

 perhaps, be open to doubt whether the methods of 

 analysis and calculation by means of which the result of 

 85 per cent, is obtained, are absolutely reliable. A 

 very slight inversion in the sugar contained in the 

 exhausted chips would lead to very erroneous conclu- 

 sions if polariscopic indications of the cane sugar 

 contained in such juice are taken as the indication of the 

 extraction. We think, therefore, that an expression 

 of 82 per cent., in view of the Magnolia results, is as 

 high as it is at present safe to calculate upon.
