Then Sindri took up a piece of gold that was so bright it lightened up the dark cavern that the Dwarfs worked in. He threw the piece of gold into the fire. Then he went to make ready something else and left Brock to work the bellows. The gadfly flew in again. Brock did not know it was there until it lighted on the back of his neck. It stung him till Brock felt the pain was wrenching him apart. But still he kept his hands on the bellows, working it so that the fire neither blazed up nor died down for a single instant. When Sindri came to look into the fire, Brock was not able to speak for pain. Again Sindri said magic words over the gold that was being smelted in the fire. He took it out of the glow and worked it over on the main-anvil. Then in a while he showed Brock something that looked like the circle of their sun. "A splendid armring, my brother," he said. "An armring for a God's right arm. And this ring has hidden wonders. Every ninth night eight rings like itself will drop from this armring, for this is Draupnir, the Ring of Increase." "To Odin, the Father of the Gods, the ring shall be given," said Brock. "And Odin will have to declare that nothing so wonderful or so profitable to the Gods was ever brought into Asgard. O Loki, cunning Loki, I shall have thy head in spite of thy tricks." "Be not too hasty, brother," said Sindri. "What we have done so far is good. But better still must be the thing that will make the Dwellers in Asgard give the judgment that delivers Loki's head to thee. Work as before, brother, and do not let the fire blaze up or die down for a single instant." This time Sindri threw into the fire a bar of iron. Then he went away to fetch the hammer that would shape it. Brock worked the bellows as before, but only his hands were steady, for every other part of him was trembling with expectation of the gadfly's sting. He saw the gadfly dart into the forge. He screamed as it flew round and round him, searching out a place where it might sting him most fearfully. It lighted down on his forehead, just between his eyes. The first sting it gave took the sight from his eyes. It stung again and Brock felt the blood flowing down. Darkness filled the cave. Brock tried to keep his hands steady on the bellows, but he did not know whether the fire was blazing up or dying down. He shouted and Sindri hurried up. Sindri said the magic words over the thing that was in the fire. Then he drew it out. "An instant more," he said, "and the work would have been perfect. But because you let the fire die down for an instant the work is not as good as it might have been made." He took what was shaped in the fire to the main-anvil and worked over it. Then when Brock's eyesight came back to him he saw a great hammer, a hammer all of iron. The handle did not seem to be long enough to balance the head. This was because the fire had died down for an instant while it was being formed.
