many city families will, at least, keep a worthless cat, 
if not also a worthless cur, the scarcity of birds need 
not puzzle us. 
I have often wondered if some species of small owl 
could not be domesticated, and displace the cat as a 
mouser. Some bird-lover ought to make careful exper-

a business are nuisances. Several periodicals and many
