When, at length, Odin found himself in the land of giants--frost giants, mountain giants, three-headed and wolf-headed giants, monsters and iron witches of every kind--he walked straight on, without stopping to fight with any one of them, until he came to the middle of Jörmungand's body. Then he seized the monster, growing fearfully as he was all the time, and threw him headlong into the deep ocean. There Jörmungand still grew, until, encircling the whole earth, he found that his tail was growing down his throat, after which he lay quite still, binding himself together; and neither Odin nor any one else has been able to move him thence. When Odin had thus disposed of Jörmungand, henceforth called the Midgard Serpent, he went on to the house of Loki's wife. The door was thrown open, and the wicked Witch-mother sat in the entrance, whilst on one side crouched Fenrir, her ferocious wolf-son, and on the other stood Hela, most terrible of monsters and women. A crowd of giants strode after Odin, curious to obtain a glance of Loki's strange children before they should be sent away. At Fenrir and the Witch-mother they stared with great eyes, joyfully and savagely glittering; but when he looked at Hela each giant became as pale as new snow, and cold with terror as a mountain of ice. Pale, cold, frozen, they never moved again; but a rugged chain of rocks stood behind Odin, and he looked on fearless and unchilled. "Strange daughter of Loki," he said, speaking to Hela, "you have the head of a queen, proud forehead, and large, imperial eyes; but your heart is pulseless, and your cruel arms kill what they embrace. Without doubt you have somewhere a kingdom; not where the sun shines, and men breathe the free air, but down below in infinite depths, where bodiless spirits wander, and the cast-off corpses are cold." Then Odin pointed downwards towards Niflheim, and Hela sank right through the earth, downward, downward, to that abyss of abysses, where she ruled over spectres, and made for herself a home called Helheim, nine lengthy kingdoms wide and deep. After this, Odin desired Fenrir to follow him, promising that if he became tractable and obedient, and exchanged his ferocity for courage, he should not be banished as his brother and sister had been. So Fenrir followed, and Odin led the way out of Jötunheim, across the ocean, over the earth, until he came to the heavenly hills, which held up the southern sky tenderly in their glittering arms. There, half on the mountain-top and half in air, sat Heimdall, guardian of the tremulous bridge Bifröst, that arches from earth to heaven. Heimdall was a tall, white Van, with golden teeth, and a wonderful horn, called the Giallar Horn, which he generally kept hidden under the tree Yggdrasil; but when he blew it the sound went out into all worlds.
