That the Polar bear does not willingly attack man, except when hotly pursued or when suffering from extreme want, is asserted by several good authorities, and confirmed by an experience which Dr. Hayes relates. He was strolling one day along the shore, and observing with much interest the effect of the recent spring-tides upon the ice-foot, when, rounding a point of land, he suddenly found himself confronted in the full moonlight by an enormous bear. It had just sprung down from the land-ice, and met Dr. Hayes at full trot, so that they caught sight of each other, man and brute, at the same moment. Being without a rifle or other means of defence, Dr. Hayes suddenly wheeled towards his ship, with much the same reflections, probably, about discretion and valour as occurred to old Jack Falstaff when the Douglas set upon him; but discovering, after a few lengthy strides, that he was not “gobbled up,” he looked back over his shoulder, when, to his gratification as well as surprise, he saw the bear speeding towards the open water with a celerity which left no doubt as to the state of its mind. It would be difficult to determine which, on this occasion, was the more frightened, the bear or Dr. Hayes! * * * * * A curious illustration of the combined voracity and epicureanism of Bruin is recorded by Dr. Kane. A _cache_, or depôt of provisions, which had been constructed by one of his exploring parties with great care, and was intended to supply them with stores on their return journey, they found completely destroyed. It had been built, with every possible precaution, of rocks brought together by heavy labour, and adjusted in the most skilful manner. So far as the means of the builders permitted, the entire construction was most effective and resisting. Yet these “tigers of the ice” seemed to have scarcely encountered an obstacle. Not a morsel of pemmican (preserved meat) remained, except in the iron cases, which, being round, with conical ends, defied both claw and teeth. These they had rolled and pawed in every direction,--tossing them about like footballs, although upwards of eighty pounds in weight. An alcohol-case, strongly iron-bound, was dashed into small fragments; and a tin can of liquor twisted almost into a ball. The bears’ strong claws had perforated the metal, and torn it up as with a chisel. [Illustration: BEARS DESTROYING A CACHE.] But the burglars were too dainty for salt meats. For ground coffee they had evidently a relish; old canvas was also a favourite,--_de gustibus non est disputandum_; even the flag which had been reared “to take possession” of the icy wilderness, was gnawed down to the very staff. It seemed that the bears had enjoyed a regular frolic; rolling the bread-barrels over the ice-foot and into the broken outside ice; and finding themselves unable to masticate the heavy India-rubber cloth, they had amused themselves by tying it up in unimaginable hard knots.
