 that such is the case widely prevails. Agri- 

 cultural societies should make all these things 

 matter of accurate special inquiry, which can 

 only be known from practical men. 



The certainty that all the gramineous tribes 

 are liable to mildew, renders it very doubtful 

 whether the extermination of this evil can ever 

 be expected ; but, unquestionably, much may 

 be done towards checking its injurious dif-
