POLAR BEAR “SILVER KING.” 
In winter, as the edge of the ice-pack moves southward, and 
in summer when it retreats northward, he follows it in 
order to keep in touch with the ringed seals and walrus 
that also go with it. 
The power of the Polar Bear to resist ice-cold water— 
nay, even to enjoy it—may fairly be regarded as one of 
the wonders of Nature. On the coast of Alaska this strange 
creature will plunge into the Arctic Ocean and swim miles 
from shore, through tossing fields of broken ice, and wher- 
ever the mother leads, her cubs follow. 
In the Autumn of 1910, the sealing steamer “Boethic” ar- 
rived at New York bringing two adult Polar Bears that were 
captured in the summer of that year by Mr. Paul J. Rainey. 
Both animals were presented to the Zoological Society, and 
the largest one ealled ‘‘Silver King’’ occupies the cage 
that was specially built for the polar bears, and the female 
is exhibited in very comfortable quarters, built for her near 
that installation. Owing to their savage temper neither 
of these bears ever can be kept with other bears, nor can 
any keeper ever enter the cage of either. ‘‘Silver King”’ 
weighs 880 pounds and is probably the largest Polar Bear 
ever captured alive and unhurt. While the female is not as 
large as ‘‘Silver King,’’ she is in every way as perfect a 
specimen.
