weekly by the secretary of the Academy to all members and 

 associate members without charge to any affiliated society. 



8. Any affiliated society may withdraw from this affiliation, by 

 a majority vote of its members, at a meeting called for this pur-

Mr. H. A. Gleason presented a paper, illustrated by many 

 photographs, on "Some Phytogeographical Features of the 

 Prairies." 



An eastern extension of the great western prairies reaches 

 across Iowa into Illinois and Indiana and portions of the ad- 

 joining states. Its flora is characterized by large numbers of 

 western plants, although a majority of the species are of the 

 eastern distribution and constitute a derived element of the
