THE ILLINOIS AUDUBON SOCIETY 
The Society was organized over sixty years ago for the protection of 
wild birdlife. Throughout its existence the Society has promoted legisla- 
tion to protect birds and to prevent the destruction of the natural areas 
that birds need for their survival. In many cases the Society has worked 
to see that existing laws are observed, since mere enactment of laws has 
not guaranteed their enforcement. We invite you to join us in advancing 
the cause of wildlife conservation and in cooperating with all other 
organizations which work for the protection of our natural resources. 
The Society maintains an office at the Chicago Natural History Mu- 
seum, Roosevelt Road and Lake Shore Drive, Chicago 5, where literature 
and information may be obtained, and where public lectures are held.
