The boar with the golden bristles
One day this giant fairy heard two stout dwarfs talking loudly in the region under the earth. They were boasting as to which could beat the other at the fire and bellows, for both were blacksmiths. One was the king of the dwarfs, who made a bet that he could excel the other. So he set them to work as rivals, while a third dwarf worked the bellows. The dwarf-king threw some gold in the flames to melt; but, fearing he might not win the bet, he went away to get other fairies to help him. He told the bellows dwarf to keep on pumping air on the fire, no matter what might happen to him.
So when one giant fairy, in the form of a gadfly, flew at him, and bit him in the hand, the bellows-blower did not stop for the pain, but kept on until the fire roared loudly, as to make the cavern echo. Then all the gold melted and could be transformed. As soon as the dwarf-king came back, the bellows-blower took up the tongs and drew out of the fire a boar having golden bristles.
This fire-born golden boar had the power of travelling through the air as swiftly as a streak of lightning. It was named Gullin, or Golden, and was given to the fairy Fro, and he, when grown, used the wonderful creature as his steed. All the other good fairies and the elves rejoiced, because men on the earth would now be helped to do great things.
Even more wonderful to tell, this fire-born creature became the father of all the animals that have tusks and that roam in the woods. A tusk is a big tooth, of which the hardest and sharpest part grows, long and sharp, outside of the mouth and it stays there, even when the mouth is shut.
When Gullin was not occupied, or being ridden by Fro on his errands over the world, he taught his sons, that is, the wild boars of the forest, how to root up the ground and make it soft for things to grow in. Then his master Fro sent the sunbeams and the warm showers to make the turned-up earth fruitful.
To do this, the wild boars were given two long tusks, as pointed as needles and sharp as knives.
