 without attempting to move from it. 



It is a singularly interesting sight to witness a

 herring in their bill) several yards from the place 

 where they made the plunge. They do not rise to 

 the surface gradually, like most divers, but sud- 

 denly, like a cork, or as if their buoyancy equalled 

 that of a bladder. The peculiar manner in which the 

 skin of this bird is attached to the body, leaving large 

 intervals where the flesh and skin seem scarcely at

 which to the spectator is extremely striking. 



During the severe winter season the solan geese
