And Cormac gave her as a household slave to his wife Ethne, who set her to grinding corn with a hand-quern, as women in Erinn were used to do.

One day as Cormac was in the palace of the Queen he saw Kiernit labouring at her task and weeping as she wrought, for the toil was heavy and she was unused to it.

Then Cormac was moved with compassion for the women that ground corn throughout Ireland, and he sent to Alba for artificers to come over and set up a mill, for up to then there were no mills in Ireland.
Now there was in Tara, as there is to this day, a well of water called _The Pearly_, for the purity and brightness of the water that sprang from it, and it ran in a stream down the hillside, as it still runs, but now only in a slender trickle.

Over this stream Cormac bade them build the first mill that was in Ireland, and the bright water turned the wheel merrily round, and the women in Tara toiled at the quern no more.

VI A PLEASANT STORY OF CORMAC'S BREHON Among other affairs which Cormac regulated for himself and all kings who should come after him was the number and quality of the officers who should be in constant attendance on the King.

Of these he ordained that there should be ten, to wit one lord, one brehon, one druid, one physician, one bard, one historian, one musician and three stewards.
The function of the brehon, or judge, was to know the ancient customs and the laws of Ireland, and to declare them to the King whenever any matter relating to them came before him.
