A Field-Book of two hundred song, game and water birds, with eighty 



full-page plates by Louis Agassiz Fuertes. 



Seventh edition. $2.00 net. 



"The author has struck the golden mean in her treatment of the different birds, 

 saying neither too much nor too Httle, but mostly furnishing information at first hand, 

 or from approved authorities. The book will be very welcome to a large number 

 who have felt the want of a work of this kind. It will increase their enjoyment of 

 outward nature, and greatly add to the pleasure of a summer vacation." — Boston 

 Herald. 



"The book is attractive, interesting and helpful, and should be in the library of 

 every lover of birds." — Science.

$2.00 net, postage 20c 



"A natural history of mammals, in which while the group is taken in systematic 

 order, the method of treatment is so popular (and at the same time so accurate) that 



it can scarcely fail to appeal to a very large series of readers a most attractive 



volume. ' ' — A^ature. 



"Interesting as fiction, scientifically exact, simply expressed, this well-prepared 

 volume will almost literally repeople the earth for many readers. Those who already 

 love natural history will rejoice in its fascinating richness of information, while it 

 would be difficult to imagine a more readable and comprehensive introduction to the 

 numerous big and little brethren of the woods and fields."
