More about Piskies by Barbara C Spooner

An old man, who would be about eighty if he were living, used to work at Merrymeet Farm, in Merrymeet. He would find the horses with tangled manes, from being piskey-ridden. And he had heard that once  a large quantity of corn on this farm was threshed by the piskies. They were overheard saying "I tweet! You tweet?" - and in the morning the corn was threshed. In this instance there is no more to the story.
     A good fright would cure the piskey-led, said the old man's daughter.
