A CAUSE OF FREAK PEAS 



By J. iSI. Van Hook 



After two years experimenting in the study and control of pea- 

 blight * due to the fungus AscocJiyta Pisi Lib., in which the ger- 

 mination of the diseased seed has been a part of the work, thou- 

 sands of diseased seedling-peas have been observed. One cause 

 for abnormal growth might be of interest to those whose atten- 

 tion has been called to freak peas by Clendenin f in the March 

 number of Torreya of last year.
