In Mr. John Burroughs' recent paper in The Atlantic Monthly^ 

 on " Real and Sham Natural History," he said : " Mr. Leander 

 S. Keyser's ' Birds of the Rockies ' tells me just what I want to know 

 about the Western birds — their place in the landscape and in the 

 season, and how they agree with and differ from our Eastern spe- 

 cies. Mr. Keyser belongs to the noble order of walkers and tramp- 

 ers, and is a true observer and bird-lover." 



" The book is beautifully illustrated. . . . Mr. Keyser is an intel- 

 ligent observer and has a good general knowledge of his subject. 

 ... A book that is well worthy of extended sale, and which occu- 

 pies a hitherto somewhat neglected field in the list of popular bird 

 books."— Dr. J. A. Allen, in The Auk, New York. 



" Mr. Keyser abandoned himself to the fascination of bird-study 

 on plains and focfthills, mountain parks and peaks, and his recountal 

 of his experiences cannot fail to arouse the spirit of desire in the 

 minds of those who follow his pages. The book possesses scientific 

 as well as literary value."— Frank M. Chapman, in Bird-Lore, New 

 York.
