The so-called Pwca'r Trwyn, which haunted the farm-house in the parish of Mynyddyslwyn, is sometimes cited as another case in which a fairy was probably a being of flesh and blood; and if this be true, it of course proves nothing but the adoption of an ancient superstition by a proscribed Welsh nobleman. There is a tradition that this fairy had a name, and that this name was 'yr Arglwydd Hywel,' which is in English 'Lord Howell.' And it is argued that this Lord, in a contest with the forces of the English king, was utterly worsted, and driven into hiding; that his tenants at Pantygasseg and the Trwyn Farm, loving their Lord, helped to hide him, and to disseminate the belief that he was a household fairy, or Bwbach. It is related that he generally spoke from his own room in this farm-house, in a gentle voice which 'came down between the boards' into the common room beneath. One day the servants were comparing their hands, as to size and whiteness, when the fairy was heard to say, 'The Pwca's hand is the fairest and smallest.' The servants asked if the fairy would show its hand, and immediately a plank overhead was moved and a hand appeared, small, fair and beautifully formed, with a large gold ring on the little finger. III. Curiously interesting is the hypothesis concerning the realistic origin of the Tylwyth Teg, which was put forth at the close of the last century by several writers, among them the Rev. Peter Roberts, author of the 'Collectanea Cambrica.' This hypothesis precisely accounts for the fairies anciently as being the Druids, in hiding from their enemies, or if not they, other persons who had such cause for living concealed in subterraneous places, and venturing forth only at night. 'Some conquered aborigines,' thought Dr. Guthrie; while Mr. Roberts fancied that as the Irish had frequently landed hostilely in Wales, 'it was very possible that some small bodies of that nation left behind, or unable to return, and fearing discovery, had hid themselves in caverns during the day, and sent their children out at night, fantastically dressed, for food and exercise, and thus secured themselves.' But there were objections to this presumption, and the Druidical theory was the favourite one. Says Mr. Roberts: 'The fairy customs appeared evidently too systematic, and too general, to be those of an accidental party reduced to distress. They are those of a consistent and regular policy instituted to prevent discovery, and to inspire fear of their power, and a high opinion of their beneficence. Accordingly tradition notes, that to attempt to discover them was to incur certain destruction. "They are fairies," says Falstaff: "he that looks on them shall die." They were not to be impeded in ingress or egress; a bowl of milk was to be left for them at night on the hearth; and, in return, they left a small present in money when they departed, if the house was kept clean; if not, they inflicted some punishment on
