THE VULTURE. 25

 heavens, as is the custom with the eagle, the glebe, 

 and some other birds of prey ; and I am even fully 

 of opinion, that when these last-mentioned birds 

 soar so high, they are not upon the look-out for food.

 down upon a mouse, and secure it as quick as thought. 

 Thus, the merlin and sparrowhawk, a little before
