 Means of the two sets of data : 



Per cent. 



Sucrose 10.67 



Glucose 3.32 



Total solids 16. 68 



The means of the above means of experimental analyses show that, 

 taken as a whole, even small quantities of sorghum have not been par- 

 ticularly suitable for sugar-making. 



If, however, we study the analyses in detail, it will be seen that the 

 sorghum often develops a surprisingly high content of sucrose, an 

 amount in fact which, could it always be produced and kept long enough 

 to allow of its manufacture, would place sorghum in the front rank of 

 sugar-producing plants. 



ANALYSES OF JUICES EMPLOYED IN MANUFACTURE. 



We turn with lively interest from the experimental laboratory to the 

 large factory. 



Unfortunately the promises of a laboratory experiment are not al- 

 ways performed in actual practice, and in the case of sorghum sugar- 

 making this fact is emphasized. 



Following are the means of the analyses of samples of large quanti- 

 ties of sorghum juices entering into the defecating pan. 



The lessons which these mean analyses teach us of the nature of sor- 

 ghum juice when produced on a large scale for manufacturing pur- 

 poses are far more valuable from a practical point of view than the 

 teachings of an experimental laboratory. 



The mean analyses are taken from the data already given. Those 

 from Weber and Scovell and Weber are from the factory at Champaign, 

 111.; those marked Scovell from the factory at Sterling, Kans. ; those 

 marked Swenson from the Hutchinson factory ; those marked Collier 

 from the large operations conducted by the Department of Agriculture 

 at Washington ; those marked Neale and Hughes from the factory at 

 Rio Grande, IN". J., and those marked Wiley from the large operations 

 carried on at Washington, Helena, Wis., Ottawa and Fort Scott, 

 Kans. 



The means of these analyses show as accurately as possible the char- 

 acter of sorghum grown on a large scale in the United States from 1880 

 until the present time. 



These are figures which do not deal with the future and the ideal, 

 but set forth in a convincing light what has actually been accomplished 

 in the growing of sorghum as a sugar-producing plant on a large scale.
