largest number of plants possible in the rows, and 
the rows wide enough apart to permit free use of 
horse implements in tillage. This may cut down 
the number of plants per acre, but it will be 
economical in the end.” 
The points clearly brought out by these experi- 
ments are: (1) that the tonnage per acre of all 
varieties is large; (2) that the percentage of dry 
matter in all varieties is low; (3) that, as a rule, 
the larger the yield the lower the percentage of dry 
matter; (4) of the varieties usually grown, the

Surehead gave the largest yields in all the years, 
whether seeded in May and afterwards thinned, or 
whether grown as plants and transplanted in June; 
(5) the early planting produces the best yield of 
both fresh substance and dry matter. The most 
important points shown by these data is that cab- 
bage does not compare favorably in yield of dry 
matter with many forage crops that require but 
two or three months for maturity, and which per- 
mits of two or three crops per year. With cabbage, 
one crop is practically all that can be grown, as it 
requires a long season.
