From Manx Soc vol IV
HE truly reigned over England ; and by his capacity so thoroughly surveyed it, that there was not a hide of land in England that he wist not who had it, or what it was worth, and afterwards set it down in his book. The land of the Britons was in his power ; and he wrought castles therein ; and ruled the Isle of Man* withal. So also he subdued Scotland by his great strength.
* In the original Mann-cynn; island of Mann.
