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 withont 
risk at any period of growth. It requires a rich 
soil in order to attain its best development. If the 
land has been well prepared, it produces very 
heavy crops. There are a number of varieties, 
both bronze and green, but the green is almost 
exclusively grown. There are hardy, or big-topped 
varieties, and small-topped kinds, which come to
