The water of this well was once considered beneficial in ophthalmia and other diseases of the eyes. There are in Radnorshire numerous springs for the cure of various diseases, and in this county also is the celebrated and well-known health resort of Llandrindod. Builth Wells, Llangamarch, and Llanwrtyd (Breconshire), are also on its borders. LLANNON (CARMARTHENSHIRE.) There is a holy Well in this parish dedicated to Non, mother of St. David. Tradition also says that Non herself got water from this well. LLANELLY. In former times there was a Holy Well in the neighbourhood of Llanelly, known as "Ffynnon Elli," supposed to possess medical qualities. HOLY WELL AT LLANGYBI. Llangybi is about four miles from Lampeter, in Cardiganshire. The Vicar, the Rev. J. N. Evans, informed me that there is a well in this parish known as "Ffynon wen," formerly supposed to possess healing powers; and that there is a tradition in the neighbourhood that St. Gybi himself lived at a house which is still called "Llety Cybi." Mr. Evans also adds in the Transactions of the Cardiganshire Antiquarian Society, Vol I., that within a quarter-of-a-mile of the Holy Well, there used to be a large stone called "Llech Gybi," which the invalids who came to this well for healing were required to touch. There is a Holy Well of St. Gybi in Carnarvonshire also, to which it was once customary for young women to travel long distances, in order to find out their lover's intentions at the forthcoming fair. A pocket handkerchief was thrown on the surface of the water, and "if it floated to the South there would be great joy and delight, but if to the North, the girl would be an old maid." THE HOLY WELL OF ST. GWENOG. St. Gwenog's Well is close to the graveyard walls of the Church of Llanwenog, which is situated about six miles from Lampeter, and two from Llanybyther. The well was once much resorted to, even within memory of people who are still alive, as its water was considered very beneficial, especially to wash children whose backs were weak. THE LLANLLWNI WELL. In the parish of Llanllwni, Carmarthenshire, there is a well called Ffynon Garedig, which seems to have been famous once. There is an old saying that if you hold your two arms in this well for a certain length of time, you will find out whether you are healthy or unhealthy. If one's arms are red when taken out of the water, it is a sign of good health, but if white, a sign of bad health. THE PWLLFFEIN WELL. Mr. Rees, Maesymeillion, Llandyssul, Cardiganshire, informed me, that there was once a famous well for its healing virtues, on the side of the river Clettwr, known as "Ffynon Pwllffein." An old man who is now dead, informed him that this well was much resorted to about the first part of the last century, and pins were once found at its bottom. The well has been destroyed by the river now.
