"As Mr. David Walter, of Pembrokeshire, a religious man, and far from fear and superstition, was travelling by himself through a field called the Cot Moor, where there are two stones set up called the Devil's Nags, which are said to be haunted, he was suddenly seized and thrown over a hedge. He went there another day, taking with him for protection a strong fighting mastiff dog. When he had come near the Devil's Nags there appeared in his path the apparition of a dog more terrible than any he had ever seen. In vain he tried to set his mastiff on; the huge beast crouched, frightened by his master's feet and refused to attack the spectre. Whereupon his master boldly stooped to pick up a stone thinking that would frighten the evil dog; but suddenly a circle of fire surrounded it, which lighting up the gloom, showed the white snip down to the dog's nose, and his grinning teeth, and white tail. He then knew it was one of the infernal dogs of hell." "THE OLD GENTLEMAN" APPEARING IN PEMBROKESHIRE, AS A BLACK CALF. A black calf was supposed to haunt a stream that flowed across the road that leads from Narberth in Pembrokeshire to the adjacent village Cold Blow. People returning late that way were sure to get frightened as they passed and, as a consequence, they would go a long distance out of their way to avoid the haunted stream. One night, or rather early morning, two villagers were going home from a fair caught the terrible calf and took it home, locking it up safely with some cattle, but it had vanished when morning came. A GHOST SEEN IN THE FORM OF A CALF IN CARDIGANSHIRE. Rhosygarth, between Llanilar and Lledrod, was a well-known haunted spot in former times. This demon often appeared on the road to travellers late at night in the form of a calf, but with a head much like that of a dog. Many years ago, Mr. Hughes, of Pantyddafad, was going home one night on horseback; but just as he was passing Rhosygarth, the ghost appeared, and passed across the road right in front of the horse. My informant, Thomas Jones, Pontrhydfendigaid, was a servant at Pantyddafad, heard the old gentleman often speaking about the ghost he had seen at Rhosygarth, and that Mr. Hughes was great-grand-father to Dr. Hughes, of Cwitycadno, Llanilar. Mr. Jones also added that he knew a young man who always laughed when people talked about seeing ghosts; but one night, a man (as he at first thought), followed him for about a mile, and after coming close to him, vanished into nothing. The young man nearly fainted, and after this never doubted the reality of the world of spirits. A DEMON ASSUMING THE FORM OF A HORSE.
