A certain mother's child had been taken away out of its cradle by the elves, and a changeling with a large head and staring eyes, which would do nothing but eat and drink, laid in its place. In her trouble she went to her neighbour, and asked her advice. The neighbour said that she was to carry the changeling into the kitchen, set it down on the hearth, light a fire, and boil some water in two egg-shells, which would make the changeling laugh, and if he laughed, all would be over with him. The woman did everything that her neighbour bade her. When she put the egg-shells with water on the fire, the imp said, "I am as old now as the Wester forest, but never yet have I seen any one boil anything in an egg-shell!" And he began to laugh at it. Whilst he was laughing, suddenly came a host of little elves, who brought the right child, set it down on the hearth, and took the changeling away with them.
