I KNOW WHAT I HAVE LEARNED}
There was once a man who had three daughters, and they were all married to trolls, who lived underground. One day the man thought that he would pay them a visit, and his wife gave him some dry bread to eat by the way. After he had walked some distance he grew both tired and hungry, so he sat down on the east side of a mound and began to eat his dry bread. The mound then opened, and his youngest daughter came out of it, and said, 'Why, father! why are you not coming in to see me?'
'Oh,' said he, 'if I had known that you lived here, and had seen any entrance, I would have come in.'
Then he entered the mound along with her.
The troll came home soon after this, and his wife told him that her father was come, and asked him to go and buy some beef to make broth with.
' We can get it easier than that! ' said the troll.
He fixed an iron spike into one of the beams of the roof, and ran his head against this till he had knocked several large pieces off his head. He was just as well as ever after doing this, and they got their broth without further trouble.
The troll then gave the old man a sack full of money, and laden with this he betook himself homewards. When he came near his home he remembered that he had a cow about to calve, so he laid down the money on the ground, ran home as fast as he could, and asked his wife whether the cow had calved yet.
