Polly Williams, a good dame who was born in Trefethin parish, and lived at the Ship Inn, at Pontypool, Monmouthshire, was wont to relate that, when a child, she danced with the Tylwyth Teg. The first time was one day while coming home from school. She saw the fairies dancing in a pleasant, dry place, under a crab-tree, and, thinking they were children like herself, went to them, when they induced her to dance with them. She brought them into an empty barn and they danced there together. After that, during three or four years, she often met and danced with them, when going to or coming from school. She never could hear the sound of their feet, and having come to know that they were fairies, took off her ffollachau (clogs), so that she, too, might make no noise, fearful that the clattering of her clog-shodden feet was displeasing to them. They were all dressed in blue and green aprons, and, though they were so small, she could see by their mature faces that they were no children. Once when she came home barefoot, after dancing with the fairies, she was chided for going to school in that condition; but she held her tongue about the fairies, for fear of trouble, and never told of them till after she grew up. She gave over going with them to dance, however, after three or four years, and this displeased them. They tried to coax her back to them, and, as she would not come, hurt her by dislocating 'one of her walking members,'[43] which, as a euphemism for legs, surpasses anything charged against American prudery.
