Innumerable are the Welsh stories of familiar spirits. Sometimes these are spectres of the sort whose antics we have just been observing. More often they are confessedly demons, things of evil. In numberless cases it is no less a personage than the diawl himself who makes his appearance in the guise of a familiar spirit. The familiar spirit which takes up its abode in the household is, as we have seen, a pranksome goblin. Its personal appearance--or rather its invisibility--is the saving circumstance which prevents it from being deemed a fairy. The familiar spirit which haunted the house of Job John Harry, at the Trwyn Farm, in the parish of Mynyddyslwyn, was a stone-thrower, a stroker of persons, etc., but could not be seen. It is famous in Wales under the cognomen of Pwca'r Trwyn, and is referred to in my account of the Ellylldan.[78] The tenants at present residing on the Trwyn Farm are strangers who have recently invaded the home of this ancestral spook, but I was able to glean abundant information concerning it from people thereabout. It made a home of Mr. Harry's house some time in the last century, for a period beginning some days before Christmas, and ending with Easter Wednesday, on which day it departed. During this time it spoke, and did many remarkable things, but was always invisible. It began at first to make its presence known by knocking at the outer door in the night; but when persons went to open the door there was no one there. This continued for some time, much to the perplexity of the door-openers. At last one night it spoke to the one who opened the door, and the family were in consequence much terrified. Some of the neighbours, hearing these tales, came to watch with the family; and Thomas Evans foolishly brought a gun with him, 'to shoot the spirit,' as he said. But as Job John Harry was coming home that night from a journey, the familiar spirit met him in the lane and said, 'There is a man come to your house to shoot me, but thou shalt see how I will beat him.' So Job went on to the house, and immediately stones were thrown at the unbelieving Thomas who had brought the gun, stones from which he received severe blows. The company tried to defend him from the stones, which did strike and hurt him, and no other person; but their efforts were in vain. The result was, that Thomas Evans took his gun and ran home as fast as his legs would carry him, and never again engaged in an enterprise of that sort.
