Note 29 — INTRODUCTION.
Reading edition
The “earth-houses” in Scotland and the isles, which seem to have been inhabited at an early period, can seldom be called hills or mounds; being built for purposes of concealment, they are usually almost on a level with the surrounding land. The Fairy hills, on the other hand, are higher and much more notable, and were probably sepulchral. This, at least, is the impression left on me by Mr. MacRitchie’s book, The Underground Life.
