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.
