Bcience. His chapter on the wild goose is as good as 

 a poem. One readily overlooks his style, which is 

 often verbose and affected, in consideration of enthu- 

 siasm so genuine and purpose so single. 



There has never been a keener eye than Audu- 

 Don's, though there have been more discriminative

 with the philomel's, and its quality is brightness and 

 vivacity, while that of the latter bird, if the books 

 are to be credited, is melody and harmony. Agaip, 

 he says the song of the blue grossbeak resembles th« 

 bobolink's, which it does about as much as the color 

 of the two birds resembles each other ; one is black 

 and white and the other is blue. The song of the 

 wood-wagtail, he says, consists of a " short succes
