AVERAGE RESULTS OF SORGHUM JUICES. 499 



Averaye Be-nUts of Analyses of Sorghum Juices during their Working 



Period. 



From what has been already said, it is clear that the best results in 

 sugar or syrup can only be secured when the seed is fully ruatured, 

 and when the specific gravity of the juices shall equal or exceed 1.066. 



If now we average the results of those analyses of sorghum juices, 

 the specific gravity of which exceeded 1 065, we find the results given 

 in the following tables. 



Although, for the greater part, the varieties under examination 

 were entiiely different, and, as wUl be seen by reference to the meteor- 

 ological data given upon page 147, the several seasons were, in their 

 climatic conditions, widely unlike, it will be found that the several 

 tables give very closely accordant results; thus fully confirming the 

 opinion that the character of the crop may be very closely ascertained 

 by the specific gravity of the juice, both as to its value for sugar and 

 syrup.
