The New Statistical Account of Scotland (written in 1845) describes cists being found on Minch Moor. Also, according to Scott’s ‘Minstrelsy of the Scottish Border’ (1802)...
There is, upon the top of Minchmuir, a mountain in Peebles-shire, a spring, called the Cheese Well, because, anciently, those who passed that way were wont to throw into it a piece of cheese, as an offering to the fairies, to whom it was consecrated.
