“ The immense size which the animal attains in the valley of the Amoor, his ferocity whetted by hunger, and the frequency of his appearance, all combine to make him the most dreaded beast of prey in the country. No wonder, therefore, that the fancy of the Gilyaks is busied with him and surrounds him, both in life and in death, with a sort of halo of superstitious fear. Thus, for example, it is thought that if a Gilyak falls in combat with a bear, his soul transmigrates into the body of the beast. ”
