The lesson of generosity is taught with force and simplicity in the legend of Hafod Lwyddog, and the necessity for secrecy is quite abandoned. Again it is a shepherd, who dwelt at Cwm Dyli, and who went every summer to live in a cabin by the Green Lake (Llyn Glas) along with his fold. One morning on awaking from sleep he saw a good-looking damsel dressing an infant close by his side. She had very little in which to wrap the babe, so he threw her an old shirt of his own, and bade her place it about the child. She thanked him and departed. Every night thereafter the shepherd found a piece of silver placed in an old clog in his cabin. Years and years this good luck continued, and Meirig the shepherd became immensely wealthy. He married a lovely girl, and went to the Hafod Lwyddog to live. Whatever he undertook prospered--hence the name Hafod Lwyddog, for Lwydd means prosperity. The fairies paid nightly visits to the Hafod. No witch or evil sprite could harm this people, as Bendith y Mamau was poured down upon the family, and all their descendants.[60] FOOTNOTE: [60] 'Cymru Fu,' 472. VI. The thought will naturally occur that by fostering belief in such tales as some of the foregoing, roguery might make the superstition useful in silencing inquiry as to ill-gotten gains. But on the other hand the virtues of hospitality and generosity were no doubt fostered by the same influences. If any one was favoured by the fairies in this manner, the immediate explanation was, that he had done a good turn to them, generally without suspecting who they were. The virtues of neatness, in young girls and servants, were encouraged by the like notions; the belief that a fairy will leave money only on a clean-kept hob, could tend to nothing more directly. It was also made a condition of pleasing the Tylwyth Teg that the hearth should be carefully swept and the pails left full of water. Then the fairies would come at midnight, continue their revels till daybreak, sing the well-known strain of 'Toriad y Dydd,' or 'The Dawn,' leave a piece of money on the hob, and disappear. Here is seen a precaution against fire in the clean-swept hearth and the provision of filled water-pails. That the promised reward did not always arrive, was not evidence it would never arrive; and so the virtue of perseverance was also fostered. Superstitions of this class are widely prevalent among Aryan peoples. The 'Arabian Nights' story of the old rogue whose money turned to leaves will be recalled. In Danish folk-lore, the fairy money bestowed on the boors turns sometimes to pebbles, and sometimes grows hot and burns their fingers, so that they drop it, when it sinks into the earth.
