The Polar Bear, (Ursus maritimus).—In nearly every col- 
lection of living bears the individuals of this species are the 
most showy and attractive. Their white coats quickly catch 
the eye of the visitor, and whether young or old, they are 
generally the most active and playful of all captive bears. 
In cold weather, when other bears lie in the sun, or, if per- 
mitted, curl up in the straw of their sleeping dens, the 
Polar Bear will disport himself in the freezing cold water 
of his swimming pool, and joyously play with a cake of ice 
until the sight of it makes one shiver. 
The Polar Bear Den is situated at the north end of Rock- 
ing-Stone Hill, about two hundred feet from the north end 
of the main series of Bear Dens. It is reached by descending 
the steps leading toward the Beaver Pond, and turning to 
the right. From the Rocking-Stone Restaurant, the Polar 
Bears are quickly reached by descending the hill toward the 
north. 
Although the Polar Bear inhabits practically the whole of 
the Arctic Ocean and its numerous islands, it is by no means 
the most northerly warm-blooded mammal. Nansen found 
fox tracks at 85° N., but the most northerly bear observed 
was on the 84th parallel. The favorite home of this ani- 
mal is the edge of the great polar ice cap, where Neptune 
and the ‘‘Frost King’’ wage continuous warfare. He seldom 
ventures more than a day’s journey inland, on any shore.
