In the agricultural districts of Wales, the fairies are accredited with a very complete variety of useful animals; and Welsh folk-lore, both modern and medieval, abounds with tales regarding cattle, sheep, horses, poultry, goats, and other features of rural life.
Therefore the tale told by Rev. Roger Rogers, of the parish of Bedwellty, sounds much less absurd in Wales than it might elsewhere.

It relates to a very remarkable and odd sight, seen by Lewis Thomas Jenkin's two daughters, described as virtuous and good young women, their father a substantial freeholder; and seen not only by them but by the man-servant and the maid-servant, and by two of the neighbours, viz., Elizabeth David, and Edmund Roger.

All these six people were on a certain day making hay in a field called Y Weirglodd Fawr Dafolog, when they plainly beheld a company of fairies rose up out of the earth in the shape of a flock of sheep; the same being about a quarter of a mile distant, over a hill, called Cefn Rhychdir; and soon the fairy flock went out of sight, as if they vanished in the air.

Later in the day they all saw this company of fairies again, but while to two of the haymakers the fairies appeared as sheep, to others they appeared as greyhounds, and to others as swine, and to others as naked infants.

Whereupon the Rev. Roger remarks:
'The sons of infidelity are very unreasonable not to believe the testimonies of so many witnesses.'
