Mynydd Rhiw

Myrddin Fardd* [..] mentioned Ffynnon Cefn Lleithfan,, or the Well of the Lleithfan Ridge, on the eastern slope of Mynydd y Rhiw, in the parish of Bryncroes, in the west of Lleyn. In the case of this well it is necessary, when going to it and coming from it, to be careful not to utter a word to anybody, or to turn to look back. What one has to do at the well is to bathe the warts with a rag or clout which has grease on it. When that is done, the clout with the grease has to be carefully concealed beneath the stone at the mouth of the well. This brings to my mind the fact that I have, more than once, years ago, noticed rags underneath stones in the water flowing from wells in Wales, and sometimes thrust into holes in the walls of wells, but I had no notion how they came there.
