The War Emergency Board of the American Phytopathological 

 Society, which was organized at the Pittsburgh meeting during the 

 hohdays, held a meeting in Washington, February 9 to 11. The organ- 

 ization of this board is the result of a determination on the part of 

 plant pathologists to do their part in winning the war. Certain prob- 

 lems of nation-wide importance are being handled. At the special 

 meeting reports on these projects were made. A census of all persons 

 able to do pathological work is being taken and encouraging progress 

 was noted. Other projects on fungicides and machinery, emergency 

 research, plant disease survey, and crop loss estimates were considered 

 at some length. Plant pathologists have in the war conditions a 

 great opportunity for service to the commonwealth, for there is no 

 more vital feature in maintaining maximum crop production than 

 that of the reduction of leakage due to crop diseases. The board is 

 working with all existing agencies of state and nation. The members
