136 SORGHUM. 



in sugar fairly comparable with the average results from our Louisiana 

 sugar-cane. 



The averageof Nos. 1, 2, 3, 4, 10, 11, 12, in available sugar, is 12.53 

 per cent of the juice. The average crop of stripped stalks per acre 

 actually obtained of these seven varieties was 26,667 pounds. 



A good mill would give 60 per cent of juice, or 16,000 pounds, and 

 12.53 per cent of this amount would give 2,005 pounds of sugar per 

 acre, as the average product to be expected from the results obtained. 



The following table gives the results obtained in working up the 

 juices from these several lots of suckered and uusuckered sorghums, 

 and the available sugar produced from each in the syrups, as also the 

 available sugar present in the juices, for purpose of comparison. 



By available sugar, is meant the diiference between the sucrose and 

 the sum of the glucose and other solids. Sucrose — (glucose, plus solids 

 not sugar)=available sugar. 



It v/ill be seen that the average available sugar from the thirty-four 

 varieties of sorghum which were suckered was 8.29 per cent of the 

 juice ; while from the unsuckered plat the average of thirty-seven va- 

 rieties was only 3.9 per cent of the juice. Also, that while the former 

 gave syrups averaging in available sugar only 32.17 per cent of their 

 weight, the latter gave syrups averaging in available sugar only 18.71 

 per cent of their weight, or 58.2 per cent of the former. It will also 

 be remembered, that the amount of* stalks grown per acre was practi- 

 cally the same, whether the crop had been suckered or not. Also, that 

 the suckered portion had been, during the season, culled of exactly one- 

 sixth of its weight of stalks for purpose of analysis, and that these 

 stalks, after being cut, sent up numerous suckers, which really lowered 

 the average per cent in available sugar which would have been other- 

 wise attained.
