Owing to the fact that the juice is practically neutral in reac- 

 tion very little loss of sucrose should occur during the boiling pro- 

 cess. It certainly seems to the writer that something ought to be 

 done to import iron pans into the district. The real difficulty in 

 introducing them lies in the fact that often such small quantities 

 of juice are boiled by one man that it would not pay him to purchase 

 an iron pan. Something however might be done in the nature of 

 co-operation among the people so that several men could combine 

 their work and purchase a pan between them. It is probable that 

 the larger scale on which the operations could be then carried out 

 would result in a saving of fuel. 



IV. METHODS OF REFINING. 



The present native method of refining by means of water weed 

 is an exceedingly slow process, but it has the advantage that very 

 little outlay is required. If, however, centrifugals could be introduced 

 the process would be a much quicker one and the turnover would be 

 much greater. The quality of sugar produced would also be much 

 better. Mr. B. C. Basu 1 carried out experiments in Jessore in 1893-4 

 with the centrifugal and obtained good results when he used good 

 quality jaggery. His remarks shew that his experiments aroused 

 great interest. He concluded that if centrifugals come into use, the 

 cultivators would soon produce a better quality jaggery. 



It would further be a good plan if the people could be induced 

 to strain their juice through cloth before boiling it down. Num- 

 berless pieces of wood, bark and other impurities are to be found in 

 the juice and on boiling these all tend to darken the syrup. 



In the meantime the people should be persuaded to clean out 

 daily the earthen boiling pans which are at present in use. They 

 could be scrubbed clean with water as is done daily in those parts 

 of Jessore district where an eating gur is made from sugarcane.
