was firm and crisp in appearance, and the remaining 31 per cent, was 

 more or less shrunken or withered. 



These latter two lots of stalks were prepared for analysis in the cus- 

 tomary manner, and dry matter and total sugar were determined.

This lot of stalks proved quite inferior in dry matter to any of the other 

 lots; but in total sugar, A was equal to any of the others of this season. 



To determine whether the 1 ss of sugars was the only destructive change 

 in the dry matter, the losses of both sugars and dry matter were com- 

 pared, as shown in Table X. It was noted that in all but two instances, 

 namely. Experiment 3, C, and Experiment 4, E, the loss of sugar sUghtly 

 exceeded the shrinkage in dry matter. This excess though small was 

 persistent.
