There was a Bwbach belonging to a certain estate in Cardiganshire, which took great umbrage at a Baptist preacher who was a guest in the house, and who was much fonder of prayers than of good ale. Now the Bwbach had a weakness in favour of people who sat around the hearth with their mugs of cwrw da and their pipes, and it took to pestering the preacher. One night it jerked the stool from under the good man's elbows, as he knelt pouring forth prayer, so that he fell down flat on his face. Another time it interrupted the devotions by jangling the fire-irons on the hearth; and it was continually making the dogs fall a-howling during prayers, or frightening the farm-boy by grinning at him through the window, or throwing the maid into fits. At last it had the audacity to attack the preacher as he was crossing a field. The minister told the story in this wise: 'I was reading busily in my hymn-book as I walked on, when a sudden fear came over me and my legs began to tremble. A shadow crept upon me from behind, and when I turned round--it was myself!--my person, my dress, and even my hymn-book. I looked in its face a moment, and then fell insensible to the ground.' And there, insensible still, they found him. This encounter proved too much for the good man, who considered it a warning to him to leave those parts. He accordingly mounted his horse next day and rode away. A boy of the neighbourhood, whose veracity was, like that of all boys, unimpeachable, afterwards said that he saw the Bwbach jump up behind the preacher, on the horse's back. And the horse went like lightning, with eyes like balls of fire, and the preacher looking back over his shoulder at the Bwbach, that grinned from ear to ear.
