In Circular No. '•> of the Purdue T'niversity l']x]ii'rinient station the 

 statement is made that "'the average (yield of wheat I oii the station farm 

 for the iiast twenty-tive years has been 28.04 bushels per acre." This is 

 nearly thirteen bushels above the average for the state. 



The question naturally arises, knowing the results obtained elsewhere 

 by studies of the internally infecting fungi of seed wheat, whether Indiana 

 varieties taken at random from a single locality may be similarly infected? 



Following the method used by T. F. Manns, thirty-four different va- 

 rieties of wheat seed were tested hy me. I shall summarize briefly the re- 

 sults of the test tind hold them tentatively against further studies on both 

 the wheat plants and seed. 



Of the thirty-four varieties, fourteen were free from fungi of any kind. 

 Thirteen of the varieties were found to be infected with a Fusariutn. Four 

 of the varieties showed an internal Macrosporium, and three varieties 

 showed both a Fiisarium and Macrosporium infection. 



The meagerness of these data, however, precludes the formation of any 

 definite conclusions, l)ut does indicate a fertile field for study.
