THE ILLINOIS AUDUBON SOCIETY, 
organized for the protection of wild birdlife, invites the attention 
of all interested in such work to the unusual opportunities the 
present time offers to advance the cause of wild life conservation. 
This work is receiving increasing support from the general pub- 
lic because of the growing appreciation of the imporiant part 
birds play in protecting grain and other food products from the 
attacks of insectivorous pests. 
The Illinois Audubon Sotiety is in perfect accord with every 
movement concerned with the preservation of plant life, animal 
life and all of our other natural resources. Every protected bit of 
landscape, every bit of forest and wayside tangle set apart for 
preservation, is speedily utilized by the birds for purposes of their 
own, and thus conservation of forest and prairie, lake and water- 
courses in their natural setting means conservation of birdlife. 
Hence the Society exerts every effort to disseminate the facts 
about the economic importance of our birdlife, and strives to 
arouse interest in the creation of wildlife refuges. 
The Society maintains an office at the Chicago Natural History 
Museum, Roosevelt Road and Lake Shore Drive, Chicago 5, where 
literature and information may be obtained, and where public 
lectures are held. Your support as a member is earnestly 
solicited. Membership fees are as follows:
