Eradication of the Ox-eye Daisy. 131 



to ripen their seeds. It may be necessary to 

 grow a crop of corn or of roots the follow- 

 ing year in order to complete the work. 



4. After-harvest and autumn cultivation, 

 follozved by spring cultivation and a cul- 

 tivated crop. V\o\\ the infested field lightly 

 after harvest, and then again deeply just 

 before winter. In the interval give the 

 soil one or more harrowings to induce the 

 daisy seeds to germinate. In the spring, 

 follow this preparation with a cultivated 

 crop, and this, if necessary, next year, by 

 another cultivated crop. 



5. Solving to rye for pasture or hay, 

 foUoiving by millet, or bare fallozv and 

 ivinter zvheat. Sow the infested field with 

 rye, and pasture the rye until June, or cut 

 it for hay. Follow^ the rye with a crop of 

 millet; or, if thought best, work the 

 ground on the bare fallow system until 

 winter wdieat may be sown in September. 

 Where it may not be desired to grow win- 

 ter wheat, the occasional stirring of the 

 soil should be continued until the close of 

 the season, that the w^eed seeds lying in the 

 soil may be made to germinate. Then 

 next season some kind of spring cereal may 

 be grown.
