Diseases of apples,— Burrill^ and Bl.\ir5 have published two bulletins 

 presenting what may be considered a summary of their extensive investigations 

 of the bitter rot of apples, both as to its botanical relations and methods of control 

 and eradication by removal of the cankers and proper spraying methods. Few 

 orchard diseases have received such attention, and every orchardist and plant 

 pathologist should read these two publications, which are too extensive to be 



summarized here. 



Ste\^ns and Hall^ have recently published a description of several apple 



diseases.
