The average analysis of cabbage, which is here 

 given, shows a much higher content of dry matter 

 than, is recorded in the Cornell bulletin; and the 

 average yield per acre, with this analysis, would 

 doubtless be much lower than is recorded in the 

 bulletin, probably nearer twenty -five tons per 

 acre, the average here assumed. 



KOHLRABI 



Kohlrabi is another valuable member of the 

 cabbage family, and one that may be fed without

 land has been well prepared, it produces very
