Note 48 — Chapter IV · THE SURVEY OF MOAB.
Reading edition
An antiquary familiar with Indian and British stone monuments, writing from Edinburgh, tells me that “cups and smoothed sloping hollows are common enough in Keltic standing-stones. The best I have seen,” he adds, “are the two on the menhirs east and west of the Frodart parish church, Strathpeffer. I think they were swearing-holes, in which the vower placed his fingers, for they are worn as smooth as glass.”
