No one of our witnesses from Central Wales is more intimately acquainted with the living folk-beliefs than Mr. J. Ceredig Davies, of Llanilar, a village about six miles from Aberystwyth; for Mr. Davies has spent many years in collecting folk-lore in Central and South Wales. He has interviewed the oldest and most intelligent of the old people, and while I write this he has in the press a work entitled _The Folk-Lore of Mid and West Wales_. Mr. Davies very kindly gave me the following outline of the most prominent traits in the Welsh fairy-belief according to his own investigations:-- _'Tylwyth Teg.'_--'The _Tylwyth Teg_ were considered a very small people, fond of dancing, especially on moonlight nights. They often came to houses after the family were abed; and if milk was left for them, they would leave money in return; but if not treated kindly they were revengeful. The changeling idea was common: the mother coming home would find an ugly changeling in the cradle. Sometimes the mother would consult the _Dynion Hysbys_, or "Wise Men" as to how to get her babe back. As a rule, treating the fairy babe roughly and then throwing it into a river would cause the fairy who made the change to appear and restore the real child in return for the changeling.' _'Tylwyth Teg' Marriage Contracts._--'Occasionally a young man would see the _Tylwyth Teg_ dancing, and, being drawn into the dance, would be taken by them and married to one of their women. There is usually some condition in the marriage contract which becomes broken, and, as a result, the fairy wife disappears--usually into a lake. The marriage contract specifies either that the husband must never touch his fairy wife with iron, or else never beat or strike her three times. Sometimes when fairy wives thus disappear, they take with them into the lake their fairy cattle and all their household property.' _'Tylwyth Teg' Habitations._--'The _Tylwyth Teg_ were generally looked upon as an immortal race. In Cardiganshire they lived underground; in Carmarthenshire in lakes; and in Pembrokeshire along the sea-coast on enchanted islands amid the Irish Sea. I have heard of sailors upon seeing such islands trying to reach them; but when approached, the islands always disappeared. From a certain spot in Pembrokeshire, it is said that by standing on a turf taken from the yard of St. David's Cathedral, one may see the enchanted islands.'[52] _'Tylwyth Teg' as Spirits of Druids._--'By many of the old people the _Tylwyth Teg_ were classed with spirits. They were not looked upon as mortal at all. Many of the Welsh looked upon the _Tylwyth Teg_ or fairies as the spirits of Druids dead before the time of Christ, who being too good to be cast into Hell were allowed to wander freely about on earth.'
