EFFECT OF LEAVING CANE CUT, UNDER SHELTER. 



In'order to ascertain the effect of leaving cane under cover, 

 two tons of Early Amber cane were cut, the juice containing 10.02 

 per cent, of cane sugar and 3.23 per cent, of glucose. One-half 

 was topped and stripped and both lots were placed on the floor of 

 the barn. The change taking place may be seen from the follow- 

 ing table:

To judge by the table the cane changes very slowly, but in 

 reality the lo^s of sugar is quite rapid. If no loss of sugar took 

 place, the juice would of course become richer in sugar, on ac- 

 count of the evaporation of part of the water. In raality this is 

 not the case. The cane sugar becomes gradually changed to glu- 

 cose, which in turn is destroyed by fermentation. Iq this way 

 the juice may become even richer in sugar, but the :^uantity of 

 juice is greatly diminished. The juice becomes also very acid. The 

 effect produced by shocking the cane in the field was tried, with 

 very unsatisfactory results, the cine sugar being destroyed very 

 rapidly.
