Every Bird-Lover in America 



Will sit up and take notice — just as this Pelican family is doing — when 

 he sees a new epoch-making work that is just emerging from the press after 

 many months of effort. It has been called 



"The Book of a Thousand Birds" 



Not since Audubon prepared his pioneer "Birds of America" has a work of such importance 

 appeared. It is the final result of a concerted effort begun many months ago, on the part of 

 foremost ornithologists, field observers, and artists, to make a complete record of our native 

 birds. Their completed work — the new BIRDS OF AMERICA — is the first story of our 

 feathered life to include them all. 



T. Gilbert Pearson 



Is editor-in-chief; JOHN BURROUGHS is consulting editor; and back of them are a score 

 of naturalists of like calibre — such men as E. H. Forbush, State Ornithologist of Massachusetts, 

 W. L. Finley, State Biologist of Oregon, Herbert K. Job, Bruce Horsfall, R. I. Brasher, and others. 



Fuertes' Beautiful Color Plates 



In addition to a wealth of field pictures and drawings, the value of this work is heightened by 

 the inclusion of over 300 color pictures, from originals by the dean of bird artists, Louis Agassiz 

 Fuertes. This is recognized as the most important series of bird studies ever made. It brings 

 into the pages a constant glow of beauty and delight. 



MAMMALS OF AMERICA 



Another section of this library describes and pictures our native mammals in the same com- 

 prehensive way. The editor-in-chief of this section is H. E. Anthony, of the American Museum 

 of Natural History. Over 500 species are included, with wonderful field pictures of living animals. 



We want to send you these unusual books 



At our expense, for personal inspection. No printed description could give you an adequate 

 idea of their beauty. You send no money. We take all the risk. Just write your name on the 

 blank below — or a letter will do. But write promptly as the first edition will soon be exhausted, 

 and then the special introductory price must be advanced.
