Academy of Sciences — Annual Reception. 



The regular June meeting of the Academy, the last of the season of 

 1891-1902, was held at the Woman's Clubhouse on Tuesday evening, June 

 10, 1902. 



Retiring President Wm. H. Knight conducted the proceedings. In 

 his introductory remarks he stated that eleven years ago a little band 

 of 21 persons interested in general science, and especially in learning 

 more of the scientific features of our region and environment, organized 

 the Southern California Science Association, which name was subsequently 

 changed to the Southern California Academy of Sciences. 



The society first met in the hall at 119 Spring street, but owing to 

 increase in numbers — now 240 — and the march of improvement in the 

 city, the Academy has since occupied the halls, successively, at 330 Broad- 

 way and 724 Broadway for its general meetings, and such other halls as 

 were convenient for its section meetings. The new board of officers hope 

 to secure a permanent home where all the meetings can be held and the 

 library and collections can be accommodated. 



New members were elected as follows : 

 E. Bennet Adams. W. J. Schaefle. Prof. F. P. Brackett, 



R. H. Behrens. D. L. Durand. Samuel S. Partello. M.D. 



H. A'. Behrens. Mark R. Lamb. James R. Rogers, Ph. D. 



Wm. J. Canfield. Alfred Fellows, M.D. 



The report of the Committee on Modern English was referred to 

 the Board of Directors for further consideration. 



Hon. Abbot Kinney addressed the meeting on "How to Identify the 

 Forest Trees of Southern California without being a Botanist." His in- 

 structive remarks were illustrated by branches and cones of the the dif- 

 ferent varieties of pin€, fir, spruce and other trees found on the slopes 

 of the Sierra Madre and other ranges of mountains in this region. He 

 explained how the pine needles spring in groups of from one to five 

 from a single sheath, according to the species to which they belong, and 

 described the characteristics of the cones peculiar to each variety.
