The latter, to be serviceable for the purpose, should be cut into the rude shapes of horses before the metamorphosis can take place. Iron of every kind keeps away malignant fairies: thus, a horseshoe nailed to the bottom of the churn prevents butter from being bewitched. Here is a form of charm against the fairies who have bewitched the butter: "Every window should be barred, a great turf fire should be lit upon which nine irons should be placed, the bystanders chanting twice over in Irish, 'Come, butter, come; Peter stands at the gate waiting for a buttered cake.' As the irons become heated the witch will try to break in, asking the people to take the irons, which are burning her, off the fire. On their refusing, she will go and bring back the butter to the churn. The irons may then be removed from the fire and all will go well." If a neighbor or stranger should enter a cottage during the churning, he should put his hand to the dash, or the butter will not come. A small piece of iron should be sewed into an infant's clothes and kept there until the child is baptized, and salt should be sprinkled over his cradle to preserve the babe from abduction. The fairies are supposed to have been conquered by an iron-weaponed race, and hence their dread of the metal. To recover a spell-bound friend, stand on All Hallows' eve at cross roads or at a spot pointed out by a wise woman or fairy doctor. When you have rubbed fairy ointment on your eyelids, the fairies will become visible as the host sweeps by with its captive, whom the gazer will then be able to recognize. A sudden gust announces their approach. Stooping down, you will then throw dust or milk at the procession, whose members are then obliged to surrender your spell-bound friend. If a man leaves home after his wife's confinement, some of his clothes should be spread over the mother and infant, or the fairies may carry them off. It is good for a woman, but bad for a man, to dream of fairies. It betokens marriage for a girl, misfortune for a man, who should not undertake serious business for some time after such dreaming. Fairy changelings may be recognized by tricky habits, constant crying, and other unusual characteristics. It was customary to recover the true child in the following way: The changeling was placed upon an iron shovel over the fire, when it would go shrieking up the chimney, and the _bona fide_ human child would be restored. It was believed that fairy changelings often produced a set of small bagpipes from under the clothes and played dance music upon them, till the inmates of the cottage dropped with exhaustion from the effects of the step dancing they were compelled to engage in.
