The academy appointed a committee, of which 

 Dr. C. N. Gould is chairman, to consider the 

 advisability of securing state aid in publishing 

 the proceedings of the academy. Another com- 

 mittee was appointed to institute a biological 

 survey of the state. Of this committee Professor 

 H. H. Lane is chairman. The academy is using 

 all the influence that can be possibly brought to 

 bear upon the people of the state to push forward 

 the study of the various animal and plant forms 

 before the influence of man disturbs natural con- 

 ditions. 



The next annual meeting of the academy will 



be held at the Central State Normal at Edmond, 

 November 26-27, 1911. jj ^ q^^^^
