Dr. E. W. Olive, of the Brooklyn Botanic Garden, spent some 

 time during the past summer assisting government and state 

 agents in locating plant diseases and instructing farmers how to 

 combat them. An account of his experiences in part of New 

 York and Virginia was given in a public lecture at the New York 

 Botanical Garden on October 26, and was accompanied by lantern 

 slides illustrating some of the most important and recently intro- 

 duced diseases. Among these were the nematode disease of 

 wheat found in Virginia and the potato wart disease discovered 

 in Pennsylvania.
