sugar is increased 17.9 over that present in those juices from stalks 

 not bearing seed. 



The practical conclusions from these results are, that there is no in- 

 comj^atibility between the maximum crop of ripe seed possible, and 

 the maximum content of sugar in the juice of the stalks ; and that, 

 owing to the more rapid development of the cane from which the seed 

 has been removed, the time necessary from planting to the maturity of 

 the crop would be shortened from seven to ten days for each of the 

 varieties, if the seed was removed early. 



By comparing the average results above given, it will be seen that in 

 the one case the stalks with the seed on had not yet attained their max- 

 imum, while in the other case they had done so, and those with which 

 they were compared, being without seed, had attained their maximum 

 sometime before, and had retained it until the others had caught up 

 with them in their sugar content. 



It is also to be observed, that those varieties in the first case where 

 the difference was so much in favor of the stalks without seed, were 

 largely the later maturing kinds, while in the second case the varieties 

 are chiefly those maturing earlier. 



An average of the number of days required from planting to matur- 

 ing, as shown by the experiments of 1882, gives for the varieties of 

 the first lot 120 days, and for those of the second lot 112 days, thus 

 confirming the conclusions above given. 



EFFECT OF STRIPPING CANE. 



On account of the trouble in stripping the stalks, experiments were 

 made, in 1879, with stalks unstripped, the tops alone being removed; 

 and these experiments appear to prove that this troublesome operation 

 of stripping may be avoided without any diminution of the amount of 

 juice or of sugar obtained therefrom. 



Below are the results obtained from stripped and unstripped sor- 

 ghum, calculated to the raw stalks used. 



By raw stalks is meant the stalks as they were cut in the field, 

 leaves, tops, and all.
