Professor Halsted has served as a member of the Advisory 

 Board of "North American Flora/' published by the New York 

 Botanical Garden, since the commencement of that work in 1905 ; 

 and, during the several years preceding, while it was in the or- 

 ganization stage, he was an active member of the group of Amer- 

 ican botanists who made the enterprise possible. He has been 

 president of the Society for the Improvement of Agricultural 

 Science and of the Botanical Society of America ; edited the 

 American Agriculturist for a period ; and has also been one of the 

 editors of the Torrey Botanical Club. 



He was a highly successful and greatly beloved teacher and in- 

 vestigator of renown. His most important publications have 

 been in the fields of agricultural botany and plant diseases, and 

 they include over 300 titles. His loss is a deep personal bereave- 

 ment to his many friends and professional associates.
