Under the direction of the Bureau of Plant Industry, 
Mr. Ellsworth Bethel, and a corps of assistants, have 
made extended explorations of the forest regions of 
California during the past season for the purpose of 
securing information relating to the biology of the rusts 
which injure forest trees. Their work has thus far 
failed to yield evidence of the presence of the much- 
dreaded blister pine rust which is causing much damage 
to the white pine forests of New England. 
The officers of the Society are : President, Dr. W. L. 
Jepson; First Vice-President, Dr. W. S. Blasdale; Sec- 
ond Vice-President, Mr. A. L. Walker; Corresponding 
Secretary, Professor C. B. Bradley, 2639 Durant Ave., 
Berkeley; Secretary-Treasurer, Miss A. E. Ehlers, 2613 
Durant Ave., Berkeley, telephone Berk. 3699; Second 
Corresponding Secretary, Professor Elizabeth Smith, 
College of Agriculture, Berkeley. 
Field trips are not only for members but for all 
interested in the native flora of California. Anyone who 
is in sympathy with the objects of the Society may be- 
come a candidate for membership. If you are a mem- 
ber and do not receive the meeting notices it is because 
you are in arrears. Send dues to Miss A. E. Ehlers,
