Whether the Polar bear hibernates during winter is not quite settled; various facts, however, point in this direction. For instance, he disappears almost completely from wintering stations during the dark time, and holes have sometimes been met with in which bears were concealed. Thus it once happened to Tobiesen that he went down with one foot into such a hole, to the no small dismay not only of the experienced walrus-hunter, but also of the bear. It is also stated that the bear during the dark time goes to the edge of the ice to seek his food. I cannot say positively whether this is the case or not; but the fact points in an opposite direction, that while only a single bear was seen in the course of the winter in the open water in the neighbourhood of our winter station at Mussel Bay in 1872-73, Palander and I almost daily saw bears on the hard frozen sea north of North East Land. Tracks of bears were visible there in all directions on the ice, and along with them light, sinuous traces of the fox. There were, on the other hand, no seal holes to be found, and it was accordingly difficult to understand wherefore the bears had chosen just this desolate stretch of ice as their haunt. The bears that were killed were besides uncommonly lean, the fat which they yielded being scarcely available as fuel for the sledge-party's cooking apparatus. During their extended excursions after prey the male and the female, the latter generally attended by one or two large young ones, keep each other company. Larger numbers are seldom seen together, unless at places where a good many carcases of walruses, seals, or white fish are lying. In former times the sight of a bear created great dismay in Polar travellers, but now the walrus-hunters do not hesitate a moment to attack, lance in hand, a large number of bears. They have sometimes in this way killed as many as twelve within a short time. They depend less on the gun. During the expedition of 1861 Carl Chydenius shot three in a few minutes, close to his tent-covered boat.
