362 TESTIMONY FOE THE BIRDS.

 and me." He protected all the birds that frequented his 

 grounds, and they devoured the insects that infested

 existence are not bigger than flies. Ten or twelve birds 

 would clear a whole field of them before they could do 

 any injury to the grass-crop. 



Small owls are useful as destroyers of the larger moths 

 and nocturnal insects, and they are excellent mousers. 

 Hon. Richard Peters, in " The Memoirs of the Philadel-

The inhabitants of a new country, like America, are not 

 so well informed of the evils that follow the destruction 

 of birds as those of old countries, who have learned from 

 the experience of many generations the indispensable 

 character of their services. Vincent Kollar says, if we 

 would prevent the increase of the cockchafer, we must 

 spare the birds that feed upon its larva. Among these 

 he thinks the crow deserves the first place. The bird
