 found. 



On my return to the United States, several days were spent in 

 California. At the Agricultural Experiment Station, Dr. F. N. 

 Briggs is carrying on interesting experiments with the bunt of 

 wheat. His investigations deal primarily with the inheritance of 

 the smut-resistant quality. The results which he has so far ob- 

 tained are extremely interesting in comparison with our own stud-

 with the problem of physiologic races of the smut. 



Opportunity was afforded for collecting the native Iris species 

 of California. Most of these were observed in their natural hab-

 at Portland, Oregon, and a visit made to the Iris garden of Mr.
