In addition to the 634 affected leaves there were removed a 

 considerable number of leaves showing brown marginal areas 

 which, upon close examination, were found to be due to causes 

 other than black rot. In four seasons' experience the writers 

 have found that in order to be on the safe side it is always neces- 

 sary to remove a good many leaves which may not be really 

 affected with black rot but which present symptoms so similar 

 that a close examination is required for a correct diagnosis. 



The principal part of the crop was harvested and marketed 

 on November 4 and 6; but some immature heads were allowed 

 to stand until November 21. For each half acre a record was 

 kept of the number of marketable heads and their weight; also 

 of the number of heads showing well defined symptoms of black 

 rot, those showing traces of black rot and those with soft rot in 

 the stem. These data are given in the following table:
