THE CABBAGE CROP. 



In the mode of attack of this disease, and its general 

 appearance, it would appear to be analogous with the

 owing to the mode of cultivating turnips, they are not 

 subject to the same examination as those which are trans- 

 planted like the cabbage. Experience has shown that 

 the disease is most common where the plants follow each 

 other too closely in succession on the same spot; that 

 plants reared on fresh soil, and even if removed to it 

 directly the disease has commenced, rarely suffer from its 

 effects ; and that the application of wood ashes effectually 

 prevents its recurrence, even in places usually subject to 

 its visitations. The value of wood ashes mainly depends 

 upon the proportion of potash they contain ; and we may 

 therefore fairly assume that an ingredient known to 

 possess such a beneficial preventive action in regard to 

 this form of disease in the coleworts, would be equally
