_The Harbour of the Island._--It must be remembered, in reading this
and other island stories, that as a rule "the harbour of the island"
is not, as might be expected, the landing-stage on the island itself,
but the port on the mainland from which ships depart to visit the
island. Thus Portraine, a place on the coast north of Dublin, is
properly _Port Rachrann_, the Port of Rachra--the port from which
voyagers sailed to Rachra, the island now called by its Norse name
Lambay.
_Parallels._--I have not found an exact parallel, but the story
belongs to the same family as that related of Coemgen, who kindled a
fire with the drops of water that fell from his fingers after washing
his hands (CS, 839).
