It is true we have a few more stories to examine, but we shall find that they all confirm this conclusion. The cases we have yet to deal with, except the first, exhibit a different and much more humane treatment of the changeling than the foregoing. The case excepted is found in Carnarvonshire, where one infallible method of getting rid of the child was to place it on the floor and let all present in the house throw a piece of iron at it. The old woman who mentioned this to Professor Rhys conjectured that the object was to convince the Tylwyth Teg, or fairy people, of the intention to kill the babe, in order to induce them to bring the right child back.[1] This would be the same motive as that which threatened death by fire or other ill-usage, in some of the instances mentioned above. But we could not thus account for the requirement that iron, and only iron, was to be used; and here we have, in fact, a superstition carefully preserved, while its meaning has quite passed out of memory. In a future chapter we shall examine the attitude of mythical beings in folk-lore to metals, and especially to iron; in the meantime we may content ourselves with noting this addition to the examples we have already met with of the horror with which they regarded it.
So far from its being always deemed wise to neglect or injure the changeling, it was not infrequently supposed to be necessary to take the greatest care of it, thereby and by other means to propitiate its elvish tribe. This was the course pursued with the best results by a Devonshire mother; and a woman at Straussberg, in North Germany, was counselled by all her gossips to act lovingly, and above all not to beat the imp, lest her own little one be beaten in turn by the underground folk.
