TABLE No. 18. Exliamtcd drip juice Continued. 



111 Table Ko. IS is shown the composition of the juices expressed from 

 the chips as discharged from the battery. The total sucrose in the fresh- 

 chip juice, as shown in Table No. 16, was 8.98 per cent. There was left 

 in the juice of the discharged chips 2.4G per cent. The juice remaining 

 in the chips suffers a slight dilution during the process of diffusion, but 

 for comparative purposes the quantity of juice in the chips before and 

 after diffusion may be taken as the same. 



In this case the percentage of juice extracted is 8.98 2.46 = 6.52 per 

 cent. The percentage of extraction, therefore, based on the percentage 

 of sucrose in juices from fresh and discharged chips, is 72.6. This is 

 about the average extraction of good milling in Louisiana, but is better 

 than the results obtained by milling sorghum. As already stated, the 

 efficiency of the apparatus was greatly increased by some changes made 

 after the season was over.
