Note 20 — INTRODUCTION.

In the Island of Colonsay there is a cairn called Carn cul ri Erin. In Bleau’s Atlas, the map of the Island of Mull marks, on the high mountain which separates the north from the south of the island, two cairns, called Carn cul ri Erin and Carn cul ri Allabyn. These seem to mark some ancient boundary; but as they are exactly in a line with Iona,—which seems to have lain so nearly on the boundary as to be claimed by both races, and also with the line which separates the ancient parishes of Killintach and Killcholumkill in Morvern, and Killintach is said, in an old document, to be in Garwmorvaren, a district which extended as far north as Loch Hourn, while Killcholumkill is said to be in Kinelbadon, which belonged to the ancient kingdom of Lorn,—there seems much reason to conclude that this may have been the line of the boundary between the Dalriad Scots from Erin and the Cruithne of Alban.
