The tales do not say what Odin thought of the gift. Perhaps he was glad that now there was no one in the whole world who could be called so wise as himself. Perhaps he was sorry for the danger into which he had thrust a poor old giant who had never done him any wrong, except to be a giant of the race which the Æsir hated. Perhaps he was a little ashamed of the trick which he had played the Vanir. Odin's new wisdom showed him how to prepare Mimer's head with herbs and charms, so that it stood up by itself quite naturally and seemed not dead. Thenceforth Odin kept it near him, and learned from it many useful secrets which it had not forgotten. So in the end Odin fared better than the unhappy Mimer, whose worst fault was that he knew more than most folk. That is a dangerous fault, as others have found; though it is not one for which many of us need fear being punished. CHAPTER XIII THE QUEST OF THE HAMMER One morning Thor the Thunderer awoke with a yawn, and stretching out his knotted arm, felt for his precious hammer, which he kept always under his pillow of clouds. But he started up with a roar of rage, so that all the palace trembled. The hammer was gone! Now this was a very serious matter, for Thor was the protector of Asgard, and Miölnir, the magic hammer which the dwarf had made, was his mighty weapon, of which the enemies of the Æsir stood so much in dread that they dared not venture near. But if they should learn that Miölnir was gone, who could tell what danger might not threaten the palaces of heaven? Thor darted his flashing eye into every corner of Cloud Land in search of the hammer. He called his fair wife, Sif of the golden hair, to aid in the search, and his two lovely daughters, Thrude and Lora. They hunted and they hunted; they turned Thrudheim upside down, and set the clouds to rolling wonderfully, as they peeped and pried behind and around and under each billowy mass. But Miölnir was not to be found. Certainly, someone had stolen it. Thor's yellow beard quivered with rage, and his hair bristled on end like the golden rays of a star, while all his household trembled. "It is Loki again!" he cried. "I am sure Loki is at the bottom of this mischief!" For since the time when Thor had captured Loki for the dwarf Brock and had given him over to have his bragging lips sewed up, Loki had looked at him with evil eyes; and Thor knew that the red rascal hated him most of all the gods. But this time Thor was mistaken. It was not Loki who had stolen the hammer--he was too great a coward for that. And though he meant, before the end, to be revenged upon Thor, he was waiting until a safe chance should come, when Thor himself might stumble into danger, and Loki need only to help the evil by a malicious word or two; and this chance came later, as you shall hear in another tale.
