The extent to which the same mill may vary at different times is 

 shown by the first three tests. Numbers 9 and 10, taken on the same 

 day, indicate that as long as a mill is working the same kind of cane 

 fairly concordant results may be obtained, also that bagasse may safely 

 be dried and preserved, at least for a short time, without changing in
