1910.] PUBLIC DOCUMENT — No. 31. 167 



N^o attempt has been made to specifically identify many of 

 these spores as that is not within the scope of this experiment. 



By disinfecting and sterilizing the seed used for germination 

 tests, and also for planting, it is believed that much of this ex- 

 cessive molding may be prevented. Work of this character is 

 being carried on in this laboratory. Some favorable results have 

 been obtained, but these have not been verified sufficiently to 

 warrant publication at present.
