The Society was organized seventy years ago for the prote 
of wild birdlife. Throughout its existence the Society has prom 
measures to protect birds and to prevent destruction of the natural | 
that birds need for their survival. In many cases the Society has wa 
to see that existing laws are observed, since mere enactment of law 
has not guaranteed their enforcement. We invite you to join us in advar 
ing the cause of wildlife conservation and in cooperating with all oth 
organizations which work for the protection of our natural resource
