SORGHUM. 



By reference to the experiments made with the small mill, and to 

 the explanation of the failure in making sugar in the large mill, it 

 will be seen that there was a difTereuce of nearly 100 per cent between 

 the per cent of available sugar in the juices of the suckered and un-

 proportion of cane from suckers in different stages of immaturity, the 

 juices from which, as we have seen, contained a minus amount of avail-

 from the mature canes. So also with the crop for the large mill, the 

 successive plantings of seed produced a lot of cane of almost every
