"I'll shape-shift myself into a boat," said the Fox. "Go on board and I'll take you over to Jura. Go to the Seven Big Women of Jura and be their servant. When they ask you what you can do, say you're good at polishing steel and iron, gold and silver. Take care you do everything well, till they trust you with the White Sword of Light. When you have a chance, run off with it, but take care the sheath does not touch anything in the house, or you'll be in trouble."
Gillie Martin the Fox changed into a boat, and Iain went on board. When the boat reached land to the north of Jura, Iain jumped ashore and went off to take service with the Seven Big Women of Jura. He reached their house and knocked on the door.
"What are you looking for?" they asked him.
"I'm looking for work," said Iain. "I can polish gold and silver, steel and iron."
"We need a lad like you," they said.
They agreed about his wages, and for six weeks Iain worked very hard. The Big Women were watching him.
"This is the best lad we've had," they said. "Now we may trust him with the White Sword of Light."
They gave him the White Sword of Light to look after, and he took great care of it, till one day the Big Women were out of the house. Iain thought this was his chance. He put the White Sword of Light into its sheath and put it over his shoulder, but going out of the door the sheath touched the lintel of the door, and the lintel screamed. The Seven Big Women came running home and took the Sword from him.
