The White Bear is terrible in its attack. Accustomed, as it is, to meet with little or no resistance, and not even suspecting danger, it rushes upon Man with a blind fury and determination too often fatal in their results. It is not an uncommon thing for White Bears to drift out to sea on floating icebergs, when they become reduced to the most frightful distress from hunger. Fatally confined to their icy raft, and utterly devoid of all means of subsistence, they ultimately attack and devour one another. The White or Polar Bear often attains a length of nine feet. Its huge limbs and powerful claws are developed in fitting proportion to the massive body; and the soles of its feet are clad with hair, enabling it to tread with safety on the slippery ice floes, where it finds a home. Purely carnivorous in its diet, the Polar Bear subsists chiefly on the Seals it contrives to trap by watching their breathing holes patiently for hours, or it may be for days together. The fur is of a dirty-white hue, inclining towards a yellowish-brown tint in the young. When the Seals are scarce, these Bears will welcome the carcase of a Whale which has floated beyond the recall of the whaler. The instinct which prompts the Esquimau to feed upon a fatty diet rich in carbon, by way of providing in his body a heat-producing basis, also leads the Bear to choose his food in the fat and blubber of the Seals and Walruses of his seas. Dr. Robert Brown, in his remarks in the “Mammals of Greenland,” tells us that he has seen upwards of twenty Polar Bears feeding on the huge inflated carcase of a Whale in Pond’s Bay, on the western shores of Davis’s Strait. The Polar Bear is hunted by the Esquimau chiefly by means of Dogs. Its flesh, however, is not very desirable. In fact, some parts of the body of the Polar Bear, such as the liver, are said to possess poisonous qualities. Scoresby relates cases of illness, and even death, which have followed upon eating the liver of this animal. The “nennok,” as the Esquimau terms the Polar Bear, is unusually regarded as a fierce and predatory animal. When irritated, or at bay, and when pressed by hunger, this Bear, like every other animal, will become dangerous. It does not grip or “hug” its enemy, but bites him. THE LABIATED, OR SLOTH BEAR. This strange specimen of the Bear family differs from all the others by its extended lips, and a tongue of remarkable length. It is a native of India and feeds mainly on vegetables. The Sloth Bear is often classed with the Borean and Malay Bears, which are natives of Malacca and the Borean Isles, and which climb trees readily and feed chiefly on fruits. These are all alike in their desire for vegetable diet and will not eat flesh except when forced to it, and they are all easily tamed and soon learn numerous tricks.
