canes. With a three-rollered mill one gets about 64 per cent. 

 The former costs Rs. 80 and the latter Rs. roo. A still high< r 

 yield (about 72 per cent.) is obtained with the help of a hori- 

 zontal roller-mill worked by steam-power. The three rollers 

 of this mill are each 6 or 7 ft. long and 30 to 32 inches in 

 diameter, and a large quantity of sugar-cane can be thus put 

 in at once into these rollers, while only 3 or 4 canes only can be 

 fed into the Behia mill, at a time. The roller mill set up at 

 the Begum Serai Indigo Factory in Bihar (which has been 

 supplied by Messrs. Jessop & Co. of Calcutta) and which 

 is worked by a 6 H. P. engine, is capable of crushing 20 tons 

 of sugar-cane per day, while a crop of 20 tons of sugar-cane 

 .which is usually obtained out of an acre) requires 10 to 12 

 days' crushing with the Behia mill. With the help of a shred- 

 der which divides up the canes longitudinally before they are 

 crushed, a higher percentage still than 72 is obtained, and 

 with the help of Faure's Decorticator which divests each cane 

 of its rind before it is crushed, as much as 80 to 84 per cent, 

 of juice is obtained out of canes. Sugar-cane contains natu- 

 rally 85 to 91 per cent, of its weight of juice, which is the 

 maximum possible yield, but no mechanical pressure can be 

 applied to get the whole of the maximum 91 per cent, out, 

 and the yield obtained by Faure's Decorticator may be looked 

 upon practically as the highest possible yield of juice obtain- 

 able. Messrs. Jules Karpeles & Co., Indigo merchants qf 

 Calcutta, are the agents for this machine. The percentage of 

 juice that is obtainable from the cane does not altogether 

 depend on the crushing mill. A cane which contains 16 per 

 cent, of fibrous matter, and 18 per cent, cf cane-sugar, would 

 yield only 45 to 50 per cent, of juice, while one containing 

 10 per cent, of fibrous matter and 18 per cent, of cane-sugar, 

 will yield about 70 per cent, with the same crushing appliance. 

 The rind and other fibrous matters, act like sponge in retain- 

 ing the juice. By getting rid of the rind one gets a higher 

 yield of juice. There may be considerations that may deter-
