Arthur Pierson Kelley was born in tlie village of Malvern, 

 in the hills suburban to Philadelphia, on August 15, 1897. He 

 studied at the University of Pennsylvania, graduating with the 

 degree of B.S. in Biol, in 1920. At the same University he ac- 

 quired the degrees of M.A. (1921) and Ph.D. (1923). Later he 

 studied plant physiology under Dr. Livingston at The Johns 

 Hopkins University. Commencing as a teacher, he was suc- 

 cessively instructor and assistant professor of botany at Rutgers 

 University. Thereafter he joined the United States Forest 

 Service hoping to find more time for research on mycorrhizae. 

 In an effort to devote himself more fully to this work he later 

 developed his private biological station and herbarium at Landen- 

 berg, Pennsylvania. From here he produced his digest of mycor- 

 rhizal literature which has become widely known. Dr. Kelley is 

 now chiefly engaged in farm life and the reconstruction of his- 

 torical farm houses, pursuits which, he writes, often leave too 

 little time for the study of mycotrophy. Dr. Kelley's early 

 publications dealt with soil acidity in relation to plant distri- 

 bution, later papers with other ecological problems and the 

 various aspects of mycotrophy.
