USEFULNESS OF BIRDS. 65 



We cannot too forcibly impress upon our country 

 friends the value they should attach to the lives of 

 these little birds, and unless for scientific purposes 

 [they should positively prohibit their being destroyed. 

 The idea that they suck the sap from the tree is toe 

 preposterous to be listened to. But the assertion 

 that they save an enormous amount of fruit from de- 

 struction by insects, is true.
