I always understood the Piskies to be little people. A great deal was said about ghosts in this place. Whether or not Piskies are the same as ghosts I cannot tell, but I fancy the old folks thought they were. A farmer who lived two miles from here, called Parson Jago to his house to have him quiet the ghosts or spirits regularly haunting it, for Parson Jago could always put such things to rest.
The clergyman went to the farmer's house, and with his whip formed a circle on the floor and then commanded the spirit, which made its appearance on the table, to come down into the circle. While on the table the spirit had been visible to all the family, but as soon as it got into the ring it disappeared; and the house was never haunted afterwards."
