The goblins turned to stone
If a man wanted to, he could make her his wife. So long as the hole was kept stopped up, by which the goblin entered, she made a good wife. If this crack was left open, or if the plug dropped out of the hole, the she-goblin was off and could never be found again.
The ruler of the goblins lived beneath the earth, as the king of the underworld. His palace was made of gold and glittered with gems. He had riches more than men could count. All the goblins and kabouters, who worked in the mines and at the forges and anvils, making swords, spears, bells, or jewels, obeyed him.
The most wonderful things about these dwarfs was the way in which they made themselves invisible, so that men were able to see neither the night mares nor the male goblins, while at their mischief. This was a little red cap which every goblin possessed, and which he was careful never to lose. The red cap acted like a snuffer on a candle, to put it out, and while under it, no goblin could be seen by mortal eyes.
Now it happened that one night, as a dear old lady lay dying on her bed, a middle-sized goblin, with his red cap on, came in through a crack into the room, and stood at the foot of her bed. Just for mischief and to frighten her by making himself visible, he took off his red cap.
When the old lady saw the imp, she cried out loudly:
"Go way, go way. Don't you know I belong to my Lord?"
But the goblin dwarf only laughed at her, with his green eyes.
Calling her daughter Alida, the old lady whispered in her ear:
"Bring me my wooden shoes."
Rising up in her bed, the old lady hurled the heavy klomps, one after the other, at the goblin's head. At this, he started to get out through the crack, and away, but before his body was half out, Alida snatched his red cap away. Then she stuck a needle in his cloven foot that made him howl with pain. Alida looked at the crack through which he escaped and found it quite sooty.
Twirling the little red cap around on her forefinger, a brilliant thought struck her.
