The large polar bear (Ursus Maritimus), with its white fur, its long, flattened head, and black claws, may be seen in great perfection at the Zoological Gardens. In its own country, during the winter, it lives chiefly on seal's flesh, but in the summer eats berries, sea-weed, and marsh plants. It is one of the most formidable of the race; and may be seen climbing mountains of ice, and swimming from floe to floe with the greatest rapidity. Captain Lyon tells us, that when a seal lies just ashore, the bear gets quietly into the water and swims away from him to leeward; he then takes short dives, and manages so that the last dive shall bring him back close to the seal, which tries to escape by rolling into the water, when he falls into the bear's paws; and if he should lie still, the bear springs upon and devours him; its favourite food, however, is the floating carcases of whales. The gait of all bears is a sort of shuffle; but this one goes at such a rate, that its pace is equal to a horse's gallop. It is remarkably sagacious, and often defeats the stratagems practised for its capture. A female with two cubs was pursued across a field of ice by a party of sailors; at first she urged the young ones to increase their speed, by running in front of them, turning round, and evincing, by gesture and voice, great anxiety for their progress; but finding that their pursuers gained upon them, she alternately carried, pushed, or pitched them forwards, until she effected their escape. The cubs seemed to arrange themselves for the throw, and when thus sent forwards some yards in advance, ran on till she again came up to them, when they alternately placed themselves before her. A she-bear and two large cubs, being attracted by the scent of some blubber, proceeding from a seahorse, which had been set on fire, and was burning on the ice, ran eagerly towards it, dragged some pieces out of the flames, and eat them with great voracity. The sailors threw them some lumps still left in their possession, which the old bear took away and laid before her cubs, reserving only a small piece for herself. As they were eating the last piece, the men shot the cubs, and wounded the mother. Her distress was most painful to behold, and, though wounded, she crawled to the spot where they lay, tore the piece of flesh into pieces, and put some before each. Finding they did not eat, she tried to raise them, making piteous moans all the time. She then went to some distance, looked back and moaned, and this failing to entice them, she returned and licked their wounds. She did this a second time, and still finding that the cubs did not follow, she went round and pawed them with great tenderness. Being at last convinced that they were lifeless, she raised her head towards the ship, and, by a growl, seemed to reproach their destroyers. They returned this with a volley of musket balls;[1] she fell between her cubs, and died licking their wounds.
