There are quite a few high divers among the 

 birds, and their beauty of form is shown to great 

 advantage in their profession. Among this class 

 of divers may be mentioned the booby, the king-

 bottom run around there for a while. The dipper 

 is especially fond of underwater haunts. There he 

 moves along, half -running and half -swimming,

 he arises to the surface and is seen to dart through 

 the foaming spray of water to a beautiful, mist-
