borhood that there is growing to be a new race of 

 birds Avho lack the fear of man their ancestors justly- 

 had. Under these conditions the wild birds, which 

 for a while we believed to have been completely driven 

 out by the sparrow, are rapidly returning to our vil- 

 lages and towns, and we have many more robins and 

 catbirds, wrens and flickers than we had ten years ago. 

 We have seen the w^orst of the English sparrow; he 

 has now found his equilibrium.
