Since it is difficult to accurately collect and weigh the fine bagasse 

 which the spent chips afford, the mean of the second column will be 

 found to represent more accurately the real extraction. It is certain 

 that with a good three-roll mill each 100 pounds of the spent chips can 

 be reduced to 30 pounds, one-third of which is combustible material. 

 Even if no attempt is made to use the bagasse as a fuel the pressure is 

 to be recommended on the score of economy. There appears to be no 

 difficulty whatever in passing the chips through a three-roll mill, and 

 their soft and pulpy state renders the pressure exceedingly easy. 



Further reference to this point will be made in that part of the report 

 devoted to sugar-cane.
