Dr. V. B. Stewart died of pneumonia on December 3, aged 

 thirty years. He held a research position as assistant professor 

 of plant pathology at Cornell University for five years, during 

 which time he made numerous contributions to his science. The 

 most notable of these concern diseases of horticultural and orna- 

 mental nursery stock. On July i last he became pathological 

 adviser to the eastern market inspectors of the U. S. Department 

 of Agriculture. This work had to do particularly with detecting 

 incipient disease in shipments of perishable plant products in- 

 tended for the army and navy. Exposure in the performance of 

 this duty led to the fatal attack. 



The Phytopathologists at their recent meeting in Baltimore

Mr. S. C. Bruner, of the Cuban Experiment Station, has
