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 too 
preposterous to be listened to. But the assertion 
that they save an enormous amount of fruit from de- 
struction by insects, is true.
