When Thor came home and saw what had happened, he was wild with fury, and guessing at once who had done the deed, he stamped off to find Red Loki, vowing that he would break every bone in his body.
Then Loki, when he heard the thunder of Thor's tramp and saw the lightning flash from his angry eyes, was terrified, and attempted to change himself into another shape; but before he could do so the wrathful god had gripped him by the throat and was shaking the life out of him.
"Let me go!" gasped Loki. "Let me go, and I will bring new hair for Sif ere the daylight's gone."
"Go, then," roared Thor, "but mind, if you break your word you will have not only to reckon with me, but with Odin and Frey as well."
Then, giving Loki a last shake, he sent him flying over the battlements and down the Rainbow Bridge like a falling star.
Now Loki was terrified at the result of his trick, and dread of the punishment that Odin might have in store for him, when he returned with the hair, began to assail him. So he determined to take back with him two presents, one for his mighty brother, and one for Frey, the god of the Golden Sunshine.
Leaping on to the earth, he quickly made his way through a hillside into the depths of the mountains, never stopping till he had reached the dark and gloomy district of Dwarfland.
For a time Loki could see nothing, though he heard on every side the tapping hammers and heaving bellows of the Little Men.
Presently, however, he distinguished a tiny furnace with its burning flame, and saw by its light a little squat figure, who pulled off his peaked cap and asked the visitor what he wanted.
"I want you to make me three gifts," said Loki; "one for Odin, and one for Frey, and the third must be golden hair that will grow upon Sif's head."
