They were taken on twelve different days, from October 15 to 27, and 

 each sample represents the mean composition of 10 tons of cane, The 

 means of the twelve samples are as follows : l 



In the juice. 



Per cent. 



Sucrose 7.28 



Glucose 3.74 



Total solids .'. 14.80 



Purity co-efficient 49.00 



MEAN COMPOSITION OF THE DIFFUSION JUICES FOR THE WHOLE 



SEASON. 



Following are the means of seventy -six analyses 2 extending over the 

 whole season. The samples were taken (a measured quantity) from 

 each cell when discharged. After ten samples were collected and mixed 

 the analysis was made. The results of the analyses are, therefore, a 

 true index of the diffusion juices for the entire season: 2 



Per cent. 



Sucrose 5. 10 



Glucose 3. 07 



Totalsolids 11.47 



Purity co-efficient 44.4 



There is one point in the above data to which I desire to expressly call 

 attention. The juice which was actually worked for sugar at Fort Scott 

 was the diffusion juice, of which the mean composition is given above. 

 This juice, according to the methods of estimating its value in common 

 use, not only would not yield crystallizable sugar, but, on the other hand, 

 could have had a large quantity of pure sugar added to it before any 

 could be obtained in the ordinary process of manufacturing. 



The above is the actual character of the juices which Dr. Collier has 

 stated had in each ton " 238.5 pounds sugar, of which 169 pounds were 

 available." 



We now turn for comparison to the data obtained with identically 

 the same processes employed at Fort Scott to make sugar from sugar 

 cane. 



The canes on which these trials were made were cut in Louisiana Oc- 

 tober 25 to 30, and subjected to diffusion at Fort Scott, November 6 and 

 7, 188G. 



MEAN COMPOSITION OF THE JUICES IN THE CANE. 



Samples of chips were taken from each cell until twelve were filled. 

 These samples were passed through the small mill and the analyses 

 made in the mixed juices. 



Five sets of analyses were made, giving the mean composition of 

 seventy-two tons of chips.
