88 FLESH-EATERS 



The bears of North America constitute four distinct 

 groups, as follows: 



PoiAR Bear, of the far North. White. Very large. 



Big Brown Bears, of Alaska. Light brown. Very large.

 new, and for several reasons its members are of unusual 

 interest.

 great ice-fields almost as far north as man has ever gone. 

 Nansen saw its tracks at Latitude 84°, — its farthest north. 



As a rule, the Polar Bear follows the edge of the great 

 ice-pack, for the sake of the seals and walruses which move 

 with it, north in summer, and south in winter. He seldom 

 travels more than a day's journey inland on any shore. His 

 food consists chiefly of seals, walruses, fish, and dead whales;
