W.E. of Hafod-y-dafol [Monmouthshire], going a journey upon the Beacon mountains (much above fourscore years ago) before sunrise, saw by his wayside the perfect likeness of a coal-race, where really there was none. There, many people were very busy: some cutting the coal; some carrying it to fill sacks; and some rising the loads upon the horses’ backs, etc. This was an agency of the fairies upon his visive faculty. This wonderful extranatural thing made a considerable impression upon his mind, and he declared it several times (once in my hearing). He was of undoubted veracity, a great man in the world, and above telling untruth. (The power of spirits, both good and bad, is very great, having not the weight of bodies to encumber and hinder their agility.) Jones
