which stealthily consume the roots of the various crops, 

 and are all the more formidable from the invisible 

 nature of their assaults. The woodpecker, fiercely ex-

 good friend to the landowner, feeding itself on the 

 minute insects that burrow into the bark or into the 

 decaying wood, and never chipping out its curious 

 tunnel except in a spot where corruption has begun and

 birds, again, have been proved as benefactors to ten 

 times the value of their depredations. In this domain 

 is no restriction. Any bird is welcome to establish 

 itself wherever it can find a suitable spot, may go
