laugh, because laughter brings deliverance."[1] The problem set before the heroes of many folk-tales is to compel laughter, but that does not seem to be intended in these changeling stories. At least I have only met with it in one, and it certainly is not common. The confession of age which the ceremony draws forth is really much more. It is a confession that the apparently human babe is an imposture, that it belongs in fact to a different race, and has no claim on the mother's care and tenderness. Therefore it is not always enough for the fraud to be discovered: active means must sometimes be taken to rid the family of their supernatural burden and regain their own little one. In Grimm's story, in which the child laughs, a host of elves comes suddenly bringing back the true and carrying away the false one; and in many of the German and Northern tales the changeling disappears in one way or other immediately after its exclamation. We are sometimes even told in so many words that the changeling had betrayed himself, and the underground folk were obliged to give back the stolen child. And in the Lithuanian story we have cited the laumes straightway falls sick and dies.[2] Such conduct accords entirely with the resentment at being recognized which we have in a previous chapter found to be a characteristic of spiritual existences. It is much more like the dislike of being found out attributed to beings who are in the habit of walking invisible, than any mystical effect of laughter.
If this be so, still less do the stories where it is required actually to drive the imp away support the learned German's contention. The means taken in these stories are very various. Sometimes it is enough to let the child severely alone, as once in the Isle of Man where a woman laid her child down in the field while she was cutting corn, and a fairy changed it there and then.
