a Excluded from average. 



From the above averages it is seen that the canes have a fairty con- 

 stant composition in all of the localities where investigations were 

 made. The canes at Guyton had the lowest content of sucrose, the 

 highest content of reducing sugar, and the lowest purity; all the others 

 run very close together. A comparison of the other analyses with the 

 samples from Kissimmee, Fla., is not permissible. Only two of the 

 samples sent from Florida (Huntington) were mill juices. The aver- 

 age of these two, as will be seen by referring to the table, agrees very 

 closely with that of the samples from the other localities. At the 

 beginning of April, 1903, two samples of canes were sent from Kis- 

 simmee, which had been growing all winter untouched by frost. The 

 sucrose in these samples had increased about 4 per cent and the reduc- 

 ing sugars were only about one-fifth as great as in the Huntington 

 samples taken earlier in the season. The purities were 13 points 

 higher than those obtained during the milling season. 



The data in general are most instructive in showing the average 

 composition of the canes of the localities inspected. When special 

 canes are selected, as has been the case in previous years, the analy-o- 

 naturally show very much better results. The real object in view, 

 however, is to obtain as exactly as possible the average composition 

 of the canes as they are delivered to the factories for commercial pur- 

 poses, and this is what has been accomplished by this investigation. 



The data show that the manufacture of sugar on a commercial scale 

 from such canes would probably not prove successful. The content of 

 sucrose is quite as high as that of the canes used for sugar making in 

 Louisiana, but the manufacturing season is shorter. Such canes
