 A HOLIDAY GIFT OF RARE AND PERMANENT VALUE 



WILD ANIMALS OF NORTH AMERICA 



Intimate Studies of the Big and Little Citizens of the Mammal Kingdom 



More than 200 illustrations: 127 Paintings reproduced in full colors; 50 Track 

 Sketches, a number of Drawings of Prehistoric Mammals and many illus- 

 trations from unusual photographs reproduced in black and white. 



THERE 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 as a Christmas gift this year. 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 qualities which science writes down in species 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 so 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 many of the mammals of North America. 



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

 life. It is a holiday gift of rare and permanent value.
