THKRE is no subject richer in fascinating interest than the study of animal life. To see all the 

 types and representative species in their native environment, to watch them meeting their respective 

 problems of life and adapting themselves to the conditions they have to face, and to follow nature 

 through its many moods as typified by its wonderful variety of mammalian forms is a delightful 

 and informative diversion. 



To do this under the guidance of one of those born observers, whose eyes are always open, whose ears 

 are always keen, whose brain is always quick to grasp, and whose pen is ever facile, is to become intimately 

 acquainted with one of the richest chapters in zoology. 



Such is to be the good fortune of those who receive a copy of the National Geographic Society's new 

 Book of Mammals. This work is the consolidation of Edward W. Nelson's splendid nature articles in the 

 Geographic. 



There is no man so well fitted to introduce you to the mammals of North America as Mr. Nelson, 



the Chief of our remarkable U. S. Biological Survey. For forty years he has been their friend, living 

 among them and studying their habits and traits in the most intimate way. To him an animal is something 

 more than flesh and bone and skin and fur. It has a personality; and he is as careful to record this as 

 to describe the formal onalities which science writes down in snecies descriptions. 



Mr. Nelson is a naturalist of the John Burroughs order. To visit the people of woodland, mountain, and 

 field with him is to discover a new world. 



Illuminating the descriptions are natural-color illustrations from the brush of that gifted artist-naturalist, 

 Louis Agassiz Fuertes. Mr. Fuertes is not only a master of color but also of pose, and he can catch the 

 timid alertness of the prong-horn antelope, the cruel sagacity of the arctic wolf, the lazy indifference of the 

 common skunk, or the wide-awake watchfulness of the gray squirrel, with equal facility. 



Added to these is a series of 50 sketches by Ernest Thompson Seton, depicting the footprints of 

 various animals as they appear in the light snow of field or forest or in the dust of the wayside. These 

 will enable the reader to identify the tracks of manv of the mammals of North America. 



Together these authorities have produced a book that is without counterpart in the literature of 

 animal life.
