nor did he, as before, make the hated sign of the cross, in offering the mead to the gods. This was guilty condescension, and he felt it: he felt, too, that he had done wrong to be present; and his anger was excited against both Sigurd and the whole pagan population of Drontheim. He vowed to be revenged,—to fall on the inhabitants with an armed force, as soon as spring appeared.[191] [Sidenote: 956 to 958.] When Hako was preparing to put his menace into execution, intelligence reached him that the sons of his brother Eric had descended on the coast of Vikia, defeated king Trygve, and were laying waste the whole province, which they were likely to subdue. To oppose the common enemy was now his object, and that of his chiefs. Even the eight pontiffs, who had been so deeply offended with his contempt of their religion, joined him: they preferred the yoke of a mild Christian to that of cruel pagans, as the sons of Eric were known to be. All hastened to the southern coast, disembarked, and joined in the battle. It was hardly contested; but, in the end, victory declared for Hako: with Guthrum, the eldest of those princes, he fought hand to hand, and killed his antagonist. Many fell; the rest hastened to their ships, and took refuge in Denmark, where they were sure of a favourable reception from Harald Blaatand. They were pursued, indeed, by the victor; but they had the advantage in celerity. In consequence of this invasion, which would, probably, be repeated, Hako revived an ancient law for the protection of his coasts,—a law once general in the north, and adopted by our Saxon kings. It divided the kingdom into maritime districts, each extending from the sea-shore as far as the rivers could boast of salmon; and each compelled to furnish a certain number of vessels and men in proportion to its extent. In each district, these ships were always to be so far ready, that, when an enemy appeared within sight, they should, before he could reach the coast, be prepared to receive him. That the alarm might be communicated from one district to another, huge trunks of trees were placed on the summits of the mountains, and formed into piles, so as to be converted into huge watch-fires whenever the occasion demanded. They extended from the extreme angle of the south, to the remotest elevation of the north. Yet these wise precautions were of no avail when the sons of Eric, at the head of a powerful Danish armament, and of such piratical vessels as they had been able to engage, next appeared off the southern coast. The watch-fires were not lighted; and the progress of the hostile fleet was unknown to the king until it was near at hand. The cause of this negligence is very imperfectly explained. Snorro says that the signal fires were always to begin in the east,—as if pirates could not land in the west or north!—and run in a line to the extreme south, then northwards, to the extremity of Norway. He adds that, as the
