Shear, for two years; Dr. R. A. Harper, for three 

 years. 



The following associate editors were elected for 

 three years: Dr. F. D. Heald, Dr. Mel T. Cook, 

 Dr. B. M. Duggar, Professor F. C. Stewart. 



Dr. Donald Eeddiek was reelected business man- 

 ager of Phytopathology. 



About fifty members were in attendance. 

 The society decided to hold its next meeting in 

 conjunction with the American Association for the 

 Advancement of Science at Philadelphia, Pa. 



The following program was presented by ab- 

 stract, the abstracts having been published and 

 distributed before the meeting. This plan was 

 undertaken in an attempt to devise some means of 

 securing time to discuss the numerous papers 

 which are offered for presentation. These ab- 

 stracts were read by the authors and formed the 

 basis of questions and discussions. The plan was 

 generally pronounced a great success, as it resulted 

 in rather a full discussion of almost every paper 

 presented.
