After a long, long time came also a skipper who wished to see the mill. He asked if it could make salt. "Yes, it could make salt," said he who owned it, and when the skipper heard that, he wished with all his might and main to have the mill, let it cost what it might, for, he thought, if he had it, he would get off having to sail far away over the perilous sea for freights of salt. At first the man would not hear of parting with it, but the skipper begged and prayed, and at last the man sold it to him, and got many, many thousand dollars for it. When the skipper had got the mill on his back he did not stay there long, for he was so afraid that the man would change his mind, and he had no time to ask how he was to stop it grinding, but got on board his ship as fast as he could.
When he had gone a little way out to sea he took the mill on deck. ";Grind salt, and grind both quickly and well," said the skipper. So the mill began to grind salt, till it spouted out like water, and when the skipper had got the ship filled he wanted to stop the mill, but whatsoever way he turned it, and how much soever he tried, it went on grinding, and the heap of salt grew higher and higher, until at last the ship sank. There lies the mill at the bottom of the sea, and still, day by day, it grinds on; and that is why the sea is salt.
