Those we speak of have for their friends the trooping fairies--the gay and sociable populace of raths and caves. Great is their knowledge of herbs and spells. These doctors, when the butter will not come on the milk, or the milk will not come from the cow, will be sent for to find out if the cause be in the course of common nature or if there has been witchcraft. Perhaps some old hag in the shape of a hare has been milking the cattle. Perhaps some user of "the dead hand" has drawn away the butter to her own churn. Whatever it be, there is the counter-charm. They will give advice, too, in cases of suspected changelings, and prescribe for the "fairy blast" (when the fairy strikes any one a tumour rises, or they become paralysed. This is called a "fairy blast" or a "fairy stroke"). The fairies are, of course, visible to them, and many a new-built house have they bid the owner pull down because it lay on the fairies' road. Lady Wilde thus describes one who lived in Innis Sark:--"He never touched beer, spirits, or meat in all his life, but has lived entirely on bread, fruit, and vegetables. A man who knew him thus describes him--'Winter and summer his dress is the same--merely a flannel shirt and coat. He will pay his share at a feast, but neither eats nor drinks of the food and drink set before him. He speaks no English, and never could be made to learn the English tongue, though he says it might be used with great effect to curse one's enemy. He holds a burial-ground sacred, and would not carry away so much as a leaf of ivy from a grave. And he maintains that the people are right to keep to their ancient usages, such as never to dig a grave on a Monday, and to carry the coffin three times round the grave, following the course of the sun, for then the dead rest in peace. Like the people, also, he holds suicides as accursed; for they believe that all its dead turn over on their faces if a suicide is laid amongst them.
