When the heralds returned they told the king of their ill success and advised him to take the girl by force. "Not so," Harold replied. "The girl has spoken well and deserves thanks instead of injury. She has put a new thought into my mind which had not come to me before. This I now solemnly vow and call God to witness, that I will not cut or comb my hair until the day when I shall have made myself king of all Norway. If I fail in this, I shall die in the attempt." [Illustration: HOUSE OF PARLIAMENT, NORWAY.] Such is the legend of Gyda and the vow. What history tells us is that the young king set out to bring all Norway under his rule and prospered in the great enterprise. One after another, the small kings yielded to his power, and were made earls or governors under him. They collected taxes and administered justice in his name. All the land of the peasants was declared to be the property of the king, and those who had been free proprietors were now made the king's tenants and were obliged to pay taxes if they wished to hold their lands. These changes angered many and there were frequent rebellions against the king, but he put them all down, and year after year came nearer the goal of his ambition. And his hair continued to grow uncut and uncombed, and got to be such a tangled mass that men called him Harold Lufa, or Frowsy-Head. There was one great and proud family, the Rafnistas, who were not easily to be won. To one of them, Kveld-Ulf, or Night-Wolf, Harold sent envoys, asking him to enter his service, but the chief sent back word that he was too old to change. Then he offered Bald Grim, old Night-Wolf's son, high honors if he would become his vassal. Bald Grim replied that he would take no honors that would give him rank over his father. Harold grew angry at this, and was ready to use force where good words would not prevail, but in the end the old chief agreed that his second son Thorolf might be the king's man if he saw fit. This he agreed to do, and as he was handsome, intelligent and courtly the king set much store by him. Not only with the Norway chiefs, but with the king of Sweden, Harold had trouble. While he was busy in the south King Erik invaded the north, and Harold had to march in haste to regain his dominions. But the greatest danger in his career came in 872, when a number of chiefs combined against him and gathered a great fleet, which attacked Harold's fleet in Halfrs-Fjord. Then came the greatest and hottest fight known to that day in Norway. Loudly the war-horns sounded and the ships were driven fiercely to the fray, Harold's ship being in the front wherever the fight waxed hottest. Thorolf, the son of Night-Wolf, stood in its prow, fighting with viking fury, and beside him stood two of his brothers, matching him blow with blow.
