that the secretary send to President Roosevelt, Secretary of the 

 Interior Ickes, Rep. H. L. Knglebright of California, Senator 

 Hiram W. Johnson, and to Mr. William G. Schulz, a petition 

 for the preservation of the Sugar Pine Forests just outside 

 Yosemite. 



A letter from Dr. A. J. Grout thanking the clul) for his elec- 

 tion to Honorary Life Membership was read. 



For the scientific part of the program. Miss Lela V. Barton 

 of the Boyce Thompson Institute talked on "Storage of Seeds." 

 She demonstrated effectively how length of seed viability de- 

 pended to a large extent upon the method of storage, and that 

 different types of seeds required different storage conditions. 

 The factors, temperature, moisture, and gaseous exchange, were 

 shown to be of prime importance in preserving the life of the 

 embryo, their effects being so inter-related that it was impossible 

 to ascertain the separate influence of each. 



The second speaker was Dr. John D. Guthrie, who discussed 

 "Chemical Changes in Plant Tissue in Relation to Respiration 

 and Dormancy." It is possible to break the dormancy of potato 

 tubers by means of various chemicals, principally ethylene 

 chlorhydrin, and potassium thiocyanate. An attempt was 

 made to show how these chemicals brought about chemical 

 changes in the tuber to increase respiration and stimulate 

 growth. It was thought that the increase in glutathione in 

 treated tubers had a direct bearing on this. 



After some discussion, the meeting was adjourned.
