St. Edren's is situated about half way between Haverfordwest and Fishguard. According to a local tradition there was once a most famous sacred well in the Churchyard, much resorted to for the cure of many complaints, especially hydrophobia; but one time, a woman washed her clothes in this well on Sunday, which caused the spring to dry up as a curse for breaking the Sabbath. Fortunately, however, for poor patients, the healing propensities or virtues of its water were miraculously transferred into the churchyard grass. So people took some of the grass to their homes to eat it with their food, which cured them of their ailments. There was a hole in the church wall to receive the offerings of those who came to procure some of this grass. One old man informed the Vicar, the Rev. J. Bowen, who is an enthusiastic antiquarian, that the sacred well had been closed in order to drain the graveyard, but that there is still a spring in a field outside the wall. THE LETTERSTON WELL. Another Pembrokeshire well supposed by some to possess curative properties is called "Ffynon Shan Shillin," at Letterston, about five miles from Fishguard. Some say that the water of the well was once so valuable that it was sold for a shilling a bottle. THE LLANLLAWER WELL. A well near the Church of Llanllawer, in the neighbourhood of Fishguard, had once the reputation of possessing medical properties, and was much frequented in the old times. There is a Rocking-Stone also in this neighbourhood, perhaps once used in divination. There was also a well near Moelgrove, between Nevern and Cardigan, which was resorted to once, and pins were discovered at the bottom of it. RHOSCROWTHER. "Down in a hollow beside the stream stands the ancient Parish Church, dedicated to St. Decumanus, patron of Springs and Wells, who in old times was held in high esteem for the cures effected at the bubbling rill hard by."--"Nooks and Corners in Pembrokeshire," page 82. ST. KEYNAN'S WELL (LLANGURIG.) According to the late Rev. Elias Owen, F.S.A., this well granted the wish of the first who drank it; and every married couple endeavoured to first drink the water, for the one did so became the master in their wedded life. LAKES. LLYN MOEL LLYN. This is a lake in the parish of Llanfihangel Genau'r Glyn, North Cardiganshire. There is a saying that every bird that attempts to fly over this lake, falls into it dead. There is also a tradition in the neighbourhood that when an attempt was made to drain the lake, terrific thunder and lightning compelled them to give up the attempt. TREGARON LAKE. There is a small lake near Tregaron, between Lampeter and Aberystwyth; and there is a tradition in the neighbourhood that the village or town of Tregaron was once situated on the spot which is now occupied by the lake, but that it sunk, and some fancy they can see some ruins or remains now at the bottom of the lake. PENCARREG LAKE.
