There are special exorcisms and preventive measures to interfere with the fairies in their quest of infants. The most significant of these, throughout Cambria, is a general habit of piety. Any pious exclamation has value as an exorcism; but it will not serve as a preventive. To this end you must put a knife in the child’s cradle when you leave it alone, or you must lay a pair of tongs across the cradle. But the best preventive is baptism; it is usually the unbaptised infant that is stolen.
