Through the valuable help of my assistant, Mrs. Marian L. Campbell. 

 we have at last caught up with the accumulated piles of unmounted speci- 

 mens and the new year will see the mounting of the accessions as they 

 come in. Mrs. Campbell has mounted 6039 specimens and Mrs. E. C. 

 Sutliife has mounted the collection she made in Sierra and Plumas 

 counties in the summer of 1918, consisting of 138 specimens which she has 

 donated to the herbarium. 



The list of accessions will be given in the general report of accessions. 



Besides the popular Sunday lectures which the curator has given at the 

 Academy, many informal talks on trees and flowers have been given to 

 various clubs and to flower shows. These help to extend the influence of 

 the Academy in popularizing science.
