THE BURGESS BIRD BOOK 

 FOR CHILDREN 



By THORNTON W. BURGESS 



With full-color illustrations of fifty-eight birds from drawings 

 by Louis Agassiz Fuertes. 



*npHIS is a story book which will be read by boys and girls with just 

 -*• as much interest and enjoyment as "The Bedtime Story. 

 Books." But it is more than a story book, it is an authoritative bird 

 book so written as to arouse the interest of even the littlest tots in their 

 feathered neighbors, and at the same time enable them to recognize 

 them. It is beautifully illustrated in colors by Mr. Fuertes, whose 

 faithful portraits of birds are famous among all bird lovers. The book 

 is designed to supply a long-felt want, a simple, interesting, intimate 

 introduction to the more common birds of the country.
