Frode gave the mill was called Hengekjapt.  King Frode had the maidservants led to the mill and requested them to grind for him gold and peace and Frode’s happiness.  Then he gave them no longer time to rest or sleep than while the cuckoo was silent or while they sang a song.  It is said they sang the song called the “Grotte Song,” and before they ended it they ground out a host against Frode, so that on the same night there came the Sea-King whose name was Mysing and slew Frode and took a large amount of booty.  Mysing took with him Grotte and also Fenja and Menja and bade them grind salt, and in the middle of the night they asked Mysing whether he did not have salt enough.  He bade them grind more.  They ground only a short time longer before the ship sank.  But in the ocean arose a whirlpool (maelstrom, mill-stream) in the place where the sea runs into the mill-eye:  the Swalchie of Stroma.

The story “Why is the sea salt?” or “How the sea became salt,” has appeared in one form or another among many nations of the world, and naturally appealed strongly to the imagination of the youth of a maritime nation like England.  The story as told formerly amongst schoolboys was as follows: 

Jack had decided to go to sea, but before doing so he went to see his fairy godmother, who had a strange looking old coffee-mill on the mantelshelf in her kitchen.  She set the table for tea without anything on it to eat or drink, and then, taking down the old mill, placed it on the table and asked it to grind each article she required.  After the tea-pot had been filled, Jack was anxious for something to eat, and said he would like some teacakes, so his fairy godmother said to the mill: 

  “Mill!  Mill! grind away. 
  Buttered tea-cakes now I pray!”

   for she knew Jack liked plenty of butter on his cakes, and out they
   came from the mill until the plate was well filled, and then she
   said: 

  “Mill!  Mill! rest thee now,
  Thou hast ground enough I trow,”

and immediately the mill stopped grinding.  When Jack told her he was going away on a ship to sea, his fairy godmother made him a present of the old mill, which he would find useful, as it would grind anything he asked it to; but he must be careful to use the same words that he had heard her speak both in starting and stopping the mill.  When he got to the ship, he stored the old mill carefully in his box, and had almost forgotten it when as they neared the country they were bound for the ship ran short of potatoes, so Jack told the Captain he would soon find him some, and ran for his mill, which he placed on the deck of the ship, and said to it: 

  “Mill!  Mill! grind away,
  Let us have some potatoes I pray!”

   and immediately the potatoes began to roll out of the mill and over
   the deck, to the great astonishment and delight of the sailors, who
   had fine fun gathering them up.  Then Jack said to the mill:
