names were Fenja and Menja. They were large and strong. About this
time were found in Denmark two millstones so large that no one had

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.

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
