It remains but to add, in connection with our household ghosts, that the method of exorcising such goblins in Wales is explicit. The objectionable spectre must be conjured, in the name of Heaven, to depart, and return no more. Not always is this exorcism effective; the ghost may have a specific purpose in hand, or it may be obstinate. The strength of the exorcism is doubled by employing the Latin language to deliver it; it receives its utmost power, however, through the clergy; three clergymen, it is thought, will exorcise any ghost that walks. The exorcism is usually for a stated period; seven years is the favourite time; one hundred years the limit. There are many instances where a ghost which had been laid a hundred years returned at the end of the time to its old haunts. In all cases it is necessary the ghost should agree to be exorcised; no power can lay it if it be possessed of an evil demon--a spirit within a spirit, as it were--which stubbornly refuses to listen to argument. In such cases the terrors of Heaven must be rigorously invoked; but the result is only temporary. Properly constituted family ghosts, however, will lend a reasonable ear to entreaty, backed by prayer. There are even cases on record where the ghost has been the entreater, as in the story of Haunted Margaret. Haunted Margaret, or Marget yr Yspryd, was a servant-girl who lived in the parish of Panteg. She had been seduced by a man who promised to marry her, and a day was set for their wedding; but when the day came, the man was not on hand, and Margaret thereupon fell on her knees in the church and prayed Heaven that her seducer might have no rest either in this world or in the world to come. In due course the man died, and immediately his ghost came to haunt Margaret Richard. People heard her in the night saying to the ghost, 'What dost thou want?' or 'Be quiet, let me alone;' and hence it was that she came to be known in that parish by the nickname of Marget yr Yspryd. One evening when the haunted woman was at the house of Mrs. Hercules Jenkins, at Trosdra, she began to be uneasy, and as it grew late said, 'I must go now, or else I shall be sure to meet him on the way home.' Mrs. Jenkins advised Margaret to speak to him; 'and tell him thou dost forgive him,' said the good dame. Margaret went her way, and as she drew near a stile at the end of a foot-bridge, she saw the ghost at the stile waiting for her. When she came up to it the ghost said, 'Do thou forgive me, and God will forgive thee. Forgive me and I shall be at rest, and never trouble thee any more.' Margaret then forgave him, and he shook hands with her in a friendly way, and vanished. CHAPTER III.
