After September 30 the numbers are as follows: 



Per cent 



Glucose in mill juices 4.15 



Not sugars in mill juices 3.75 



Ratio 1 glucose to .90 not sugars. 



Glucose in chips 4. 15 



Not sugars in chips (calculated) 3.74 



Sucrose 7.01 



Total solids 14.90 



Purity of chips before October 1 60.5 



Purity of chips after September 30 47. 1 



SAMPLES OF CHIPS CORRECTED NUMBERS. 



A full discussion of the data obtained by the analyses of the chips 

 entering the battery has already been given. 

 Per hundred parts of sucrose the glucose was as follows: 



Per cent. 



Before October 1 37.52 



After September 30 59.18 



A comparison of these ratios with those of the mill juices affords a con- 

 nrmation of the supposition already expressed that as the canes deterio 

 rate the rate of inversion on heating in a closed flask is greatly increased. 



The analyses, therefore, of the mill juices after September 30 give the 

 only fair idea of the character of the cane worked up to October 15. 

 After that date the analyses of the juice of the chips pressed out by the 

 experimental mill gives the best results possible. Sampled as the chips 

 were, by taking an equal portion from each cell and mixing these sub- 

 samples from ten cells together, the juice expressed therefrom is a fair 

 representation of the character of the chips entering the battery. 



JUICE FROM CHIPS PASSED THROUGH EXPERIMENTAL MILL. 



From the analyses of the juices it is seen that the chips entering the 

 battery from October 15 to the close of the season contained : 



Per cent. 



Sucrose 6.48 



Glucose 3.31 



(;im OHO per hundred of sucrose 51.07 



Leaving out of the computation the analyses of the chips in closed 

 bottles, the following mean character of the cane for the entire season 

 is obtained :
