restored them as a recompense for their assistance in the battle fought by him between 969 and 995 against Finleac MacRuari, Maormor of North Moray, at Skidamyre in Caithness.  Whether it was the Orkney jarls or their superiors, the kings of Norway, who owned them in the meantime, the odal lands were finally sold back to those entitled to them by descent by Jarl Ragnvald Kol’s son about 1137, in order to raise money for the completion of Kirkwall Cathedral.  Odal tenure in Orkney was thus in abeyance for over two centuries, save for a short time, and in any case its inherent principle of subdivision would have killed it, and after its renewal, in spite of its many safeguards against alienation to strangers, it gradually died out under feudalism and Scottish law and lawyers.[19] In Cat it never seems to have taken root.

After holding the jarldom for a long term, Torf-Einar died in his bed, as the Saga contemptuously tells us, probably in or after the year 920, leaving three sons, Arnkell, Erlend, and Thorfinn Hausa-kliufr or Skull-splitter, of whom the two first, Arnkell and Erlend, fell with Eric Bloody-axe, king of Norway, in England.  The third son, Thorfinn Hausa-kliufr or Skull-splitter, himself about three-quarters Norse by blood, married Grelaud, daughter of Dungadr, or Duncan, the Gaelic Maormor of Caithness by Groa, daughter of Thorfinn the Red, thus further Gaelicising the strain of the Norse Jarls of Orkney,[20] but adding greatly to their mainland territories.

Jarl Thorfinn Hausa-kliufr, who flourished between 920 and 963, is described as a great chief and fighter; but he, like his father, died a peaceful death, and was buried at Hoxa, Haugs-eithi or Mound’s-isthmus, which covers the site of a Pictish broch, near the north-west end of South Ronaldshay.[21]

When Eric Bloody-axe had been defeated and killed, his sons came to Orkney and seized the jarldom, and his widow, the notoriously wicked Gunnhild and her daughter Ragnhild settled there for a time.  Thorfinn Hausa-kliufr had five sons, Arnfinn, Havard, Hlodver, Ljotr and Skuli.  Three of these, Arnfinn.  Havard and Ljotr, successively married Ragnhild, and Ragnhild rivalled her mother in wickedness.  Arnfinn she killed at Murkle in Caithness with her own hand; Havard she induced Einar Oily-tongue, his nephew, to slay, on her promise to marry him, which she broke; and finally she married Jarl Ljotr instead.  Skuli, the only other surviving son save Hlodver, went to the king of Scots, who is said to have lightly given away what did not belong to him, and to have created him Earl of Caithness, which then included Sudrland.[22] Skuli then raised a force in his new earldom, no doubt to carry out Scottish policy, and, crossing to Orkney, fought a battle there with his brother Ljotr, was defeated, and fled to Caithness.  Collecting another army in Scotland, Skuli fought a second battle at Dalar or Dalr, probably Dale in the upper valley of the Thurso River in Caithness, and was there defeated and killed by Ljotr, who took possession of his dominions.  Then followed a battle between Ljotr and a Scottish earl called Magbiod or Macbeth, at Skida Myre or Skitten Moor in Watten in Caithness, which Ljotr won, but died of his wounds shortly after, and is said to have been buried at Stenhouse in Watten.[23] Thus the first Scottish attempt at consolidation of the north failed.
