"Nothing is more striking than the general simi- 

 larity in nature, actions, appearance, and habits of 

 both the brown bears of the humid coast region of 

 Alaska and the grizzlies of the dry interior. The 

 several species of both the coast and inland bears 

 differ more or less widely in size, anatomy, color, 

 and claws, but no one can observe them in their 

 natural habitats without realizing that all have de- 

 scended from a common ancestor." 



The little that I have seen of the polar bear sug- 

 gests to me that he may be related to the grizzly. 

 It is interesting that the coats of the polar bear 

 are uniformly white, while those of the grizzly are 

 of assorted colors. 



The grizzly is scattered over a vast and varied 

 range, feeds on a variety of food, and is divided into 

 numerous species and subspecies, but he ever runs 

 true to character, everywhere is one hundred per 

 cent grizzly. The chief points of dissimilarity in the 

 different species are the shape of the skull and the 

 character of the teeth. Rarely is there any differ- 

 ence apparent in the living animals; the classifica- 

 tion is determined chiefly from the teeth and the 

 formation of the skull. 



Color is no clue to the species. Color may vary as
