I just stumbled upon this Norwegian tale...
Once upon a time there was a dear, brave boy who had nothing on earth but a blind grandmother and a clear conscience. After finishing school he became a ship's boy and was about to begin his first journey. He saw that all his new comrades were gambling with good money, but he had nothing, not even a penny. This saddened him, and he complained to his grandmother. She thought for a while, then limped into her room and returned with a small mill, which she gave to the boy, saying, "If you say to the mill, 'Mill, mill, grind for me; grind this or that for me at once!' then it will grind for you whatever you want. And when you say, 'Mill, mill, stand still, for I want nothing more!' then it will stop grinding. But say nothing about this, or it will bring you misfortune!"
The boy thanked her, said farewell, and boarded his ship. When his comrades again began to gamble with their money, he took his mill into a dark corner and said, "Mill, mill, grind for me; grind golden ducats for me at once!" and the mill ground out ducats of pure gold that fell ringing into his leather cap.
When the cap was full he said, "Mill, mill, stand still, for I want nothing more!" and it stopped grinding. He was now the richest of all his comrades.
The ship's captain was very miserly, and whenever there was not enough to eat, the boy had only to say, "Mill, mill, grind for me; grind fresh bread for me at once!" and it would grind away until he said the other words. The mill ground out anything for him that he wanted.
His comrades often asked him how he got these good things, but he said only that he was not at liberty to tell them. However, they continued to press him, until at last he told them the whole story.
It was not long before the evil ship's captain got wind of this, and he immediately hatched a plot. One evening he called the boy into his cabin and said, "Fetch your mill and grind out some fresh chickens for me!"
The boy went and brought back a basket full of fresh chickens, but the godless man was not satisfied. He beat the poor boy until he brought the mill to him and told him what he had to say to make it grind. However, the boy did not tell him how to make it stop, and the captain did not think to ask him about this.
Afterward when the boy was standing alone on deck, the captain went to him and pushed him into the sea, not thinking at all about how much care and concern his father and mother had given for him, nor how his blind grandmother was hoping for his return. He pushed him into the sea, then said that he accidentally had fallen overboard, thinking that this was the end of the story.
Then he went into his cabin and said to the mill, "Mill, mill, grind for me; grind salt for me at once!" and the mill ground out grains of pure white salt.
When the bowl was full the ship's captain said, "That is enough!" but the mill continued to grind forth. Whatever the captain said or did, the mill ground away until the entire cabin was full. He took hold of the mill to throw it overboard, but received such a blow that he fell to the floor as though stunned. The mill continued to grind forth until the entire ship was full and was beginning to sink.
Finally the ship's captain grabbed his sword and chopped the mill into tiny pieces; but behold, every little piece became a little mill, and all the mills ground out grains of pure white salt.
It was soon over for the ship. It sank with man and mouse and all the mills. These are still grinding out grains of pure white salt at the bottom of the sea. And even if you were to shout out the correct command, they are so deep that they would not hear it. And that is why seawater is so salty.
