THE AMERICAN ASSOCIATION FOR TEE 



ADVANCEMENT OF SCIENCE. 

 SECTION I^SOGIAL AND ECONOMIC 



SCIENCE. 



Thirty-five papers were on the printed 

 program, of which seventeen were read in 

 person, seven by title with abstracts of 

 contents presented and eight papers were 

 never forwarded by the authors, for vari- 

 ous reasons. The statistical paper by 

 Professor Arthur Lefevre on 'Public Edu- 

 cation in Texas,' arrived too late for use. 



Professor W. R. Lazenby's paper on 

 'Relations of Forestry to Soil and Climate' 

 will appear in the Proceedings of the Ohio 

 State Forestry Society at some future date. 



The paper read by Professor Bruce R. 

 Payne, University of Virginia, on 'The 

 Social Service of the Public High School,' 

 will also be published later. 



Attendance at the meetings ranged from 

 fifteen to fifty persons. Holding the ses- 

 sions at the board of trade rooms was a 

 mistake. The business people did not at- 

 tend, and we were too far away from the 

 other sections to admit of their members 

 attending. 



The following officers were elected: 



Sectional Committee — Irving Fisher, Charles A. 

 Conant, Carroll D. Wright (five years), E. L. 

 Corthell (four years), W. R. Lazenby (three 

 years), Frank A. Putter (two years) and B. E. 

 Ferno w ( one year ) . 



Member of Council — ^Marcus Benjamin. 



Member of General Committee — Le Grand 

 Powers. 



Possibilities of Cotton Warehousing from, 

 the Producer's Standpoint: Eugene 

 Williams, Waco, Texas.
