CANE SUGAR. 



Distribution of Sugar in the Cane. The cane is not of 

 uniform composition throughout its length, and it is this property that makes it 

 a matter of such difficulty to obtain representative analyses of large quantities 

 of cane. The annexed table of analyses by Boname 2 illustrates this point. 



A. Plant cane, imperfectly ripe and still in full vegetation. 



B. Second ratoons, 11 months old. 



C. Fourth ratoons in vegetation. 



D. First ratoons, 11 months old. 



E. Creole cane, the stalk 1 metre long and 10 cm. in circumference. 



F. Plant cane, very ripe, 14 months old.

The variation in composition of the juice in the nodes and internodes is 

 given by Boname.

Stubbs 2 gives the following as the result of analyses of twenty stalks of 

 purple cane :

The great variation in composition of juice at nodes and internodes is well 

 shown in the tables quoted above and an explanation given of the decreased sugar 

 content of second mill juice compared with first mill juice, the more woody nodes 

 only yielding their juice on a more powerful crushing.
