HAKON, in late times, had heard of a famous stir. ring person, victorious in various lands and seas, latterly united in sea-robbery with Svein, Prince Royal of Denmark, afterwards King Svein of the Doublebeard ('Zvae Skiaeg,' Twa Shag), or fork-beard, both of whom had already done transcendent feats in the viking way during this copartnery. The fame of Svein, and this stirring personage, whose name was 'Ole,' and, recently, their stupendous feats in plunder of England, siege of London, and other won. ders and splendours of viking glory and success, had gone over all the North, awakening the attention of Hakon. and everybody there. The name of 'Ole' was enigmatic, mysterious, and even dangerous-looking to Hakon Jarl, who at length sent out a confidential. spy to investigate this 'Ole,' -- a feat which the confidential spy did completely accomplish -- by no means to Hakon's profit! The mysterious 'Ole' proved to be no other than Olaf, son of Tryggve, destined to blow Hakon Jarl suddenly into destruction, and become famous among the heroes of the Norse world.
