Note 91 — PRE-COLUMBIAN DISCOVERY.

Æyrar. This is not the name of a place—for Heriulf dwelt in Iceland at a place called Dropstock—but of a natural feature of ground; eyri, still called an ayre in the Orkney islands, being a flat, sandy tongue of land, suitable for landing and drawing up boats upon. All ancient dwellings in those islands, and probably in Iceland also, are situated so as to have the advantage of this kind of natural wharf, and the spit of land called an ayre, very often has a small lake or pond inside of it, which shelters boats.—Laing.
