"But still that jolly mariner Took in no reef at all; For in his pouch confidingly He wore a baby's caul."
It little availed him, however; for as soon as the storm in ruthless fury burst upon his frail bark, he
"Was smothered by the squall. Heaven ne'er heard his cry, nor did The ocean heed his _caul_!"
Advocates also purchased them, that they might be endued with eloquence, the price paid having often been from twenty to thirty guineas. They seem to have had other magical properties, as Grose informs us that any one "possessed of a caul may know the state of health of the person who was born with it. If alive and well, it is firm and crisp; if dead or sick, relaxed and flaccid." In France the luck supposed to belong to a caul is proverbial, and _être né coiffé_ is an expression signifying that a person is extremely fortunate. Apart from the ordinary luck supposed to attach to the "caul," it may preserve the child from a terrible danger to which, according to the old idea, it is ever exposed--namely, that of being secretly carried off and exchanged by some envious witch or fairy for its own ill-favoured offspring. This superstition was once very common in many countries, and was even believed by Martin Luther, if we are to rely on the following extract from his "Table Book:"--"Changelings Satan lays in the place of the genuine children, that people may be tormented with them. He often carries off young maidens into the water." This most reprehensible of the practices attributed to the fairies is constantly spoken of by our old writers, and is several times mentioned by Shakespeare. In the speech of Puck, in _A Midsummer Night's Dream_ (Act ii., sc. 1), that jovial sprite says of Titania's lovely boy--the cause of quarrel between the King and Queen of Elfland:--
In the _Winter's Tale_ (Act iv., sc. 4) the Shepherd, on discovering the babe Perdita, tells the Clown, "It was told me I should be rich by the fairies. This is some changeling." As a preservation against this danger, sundry charms are observed. Thus, in the North of England, a carving-knife is still hung from the head of the cradle, with the point suspended near the child's face. In the Western Isles of Scotland idiots are believed to be the fairies' changelings, and in order to regain the lost child, parents have recourse to the following device:--They place the changeling on the beach, below high-water mark, when the tide is out, and pay no heed to its screams, believing that the fairies, rather than allow their offspring to be drowned by the rising waters, will convey it away and restore the child they had stolen. The sign that this has been done is the cessation of the child's crying. In Ireland, too, the peasants often place the child supposed to be a changeling on a hot shovel, or torment it in some other way. A similar practice is resorted to in Denmark, where the mother heats the oven, and places the child on the peel, pretending to put it in; and sometimes she whips it severely with a rod, or throws it into the water. The only real safeguard, however, against this piece of fairy mischief is baptism, and hence the rite has generally been performed among the peasantry as soon as possible after birth.
