Huge blocks of earth-brown stone were cast into the furnace until they were in a white heat, when drop by drop red gold trickled from them into the ashes. This was all gathered together, and the glistening heap taken to the dwarf women, who, crushing it in their hands before it had hardened, drew it out upon their wheels, and spun it into fine soft hair. While they were doing this Brok sought amongst his treasures until he found the blue of the ocean and the tough inner pith of an underground tree; these, with other things, were cast into the furnace, and afterwards beaten with his hammer. As the rhythmic strokes fell, the women sang a song which was like the voice of a strong, steady wind. Then when this work was finished, the smith drew forth a little ship, which was carefully placed on one side. The third time the dwarf went to a dark corner, and brought out an ugly bent bar of iron, and this, with two feathers from the wings of the wind, was heated to melting whiteness, and wrought with great cunning and extreme care, for it was to be a spear for Odin himself, the greatest of all the heroes.
Then Brok and Sindri called Loki to them and giving him these three things bade him hasten back to the gods at Asgard and appease their wrath. Loki, however, was already beginning to feel sorry that he had been so successful; he liked teasing folk but he did not like having to atone for his mischief afterwards. He turned the marvelous gifts over scornfully in his hands, and said that he did not see anything very wonderful in _them;_ then, looking at Sindri he added, "However, Brok has hammered them very skilfully, and I will wager my head that you could not make anything better."
Now the brother dwarfs had not by any means expected gratitude, but neither had they expected any such rudeness as this, so Sindri determined to give Loki a lesson. Going to one corner of the smithy he picked up a pig-skin and taking the hammer in his hands, told his brother to blow steadily, neither to falter nor to fail until he passed the word that the work was done. Then with strength and gentleness he wrought with his tools, having cast nothing into the heat but the pig-skin; with mighty blows and delicate touches he brought thickness and substance into it, until a board looked at him from the flames. Loki, fearing for his head, changed himself into an enormous forest fly, and settling upon Brok's hand, stung with vicious fury; but the dwarf would not trouble to brush the fly away, and steadily moved the bellows until his brother called to him to stop, when they drew forth a strong flexible boar whose bristles were of the finest gold.
