There was once a merchant who had only one child, a son, that was very young, and barely able to run alone. He had two richly laden ships then making a voyage upon the seas, in which he had embarked all his wealth, in the hope of making great gains, when the news came that both were lost. Thus from being a rich man he became all at once so very poor that nothing was left to him but one small plot of land; and there he often went in an evening to take his walk, and ease his mind of a little of his trouble.
One day, as he was roaming along in a brown study, thinking with no great comfort on what he had been and what he now was, and was like to be, all on a sudden there stood before him a little, rough-looking, black dwarf. 'Prithee, friend, why so sorrowful?' said he to the merchant; 'what is it you take so deeply to heart?' 'If you would do me any good I would willingly tell you,' said the merchant. 'Who knows but I may?' said the little man: 'tell me what ails you, and perhaps you will find I may be of some use.' Then the merchant told him how all his wealth was gone to the bottom of the sea, and how he had nothing left but that little plot of land. 'Oh, trouble not yourself about that,' said the dwarf; 'only undertake to bring me here, twelve years hence, whatever meets you first on your going home, and I will give you as much as you please.' The merchant thought this was no great thing to ask; that it would most likely be his dog or his cat, or something of that sort, but forgot his little boy Heinel; so he agreed to the bargain, and signed and sealed the bond to do what was asked of him.
But as he drew near home, his little boy was so glad to see him that he crept behind him, and laid fast hold of his legs, and looked up in his face and laughed. Then the father started, trembling with fear and horror, and saw what it was that he had bound himself to do; but as no gold was come, he made himself easy by thinking that it was only a joke that the dwarf was playing him, and that, at any rate, when the money came, he should see the bearer, and would not take it in.
About a month afterwards he went upstairs into a lumber-room to look for some old iron, that he might sell it and raise a little money; and there, instead of his iron, he saw a large pile of gold lying on the floor. At the sight of this he was overjoyed, and forgetting all about his son, went into trade again, and became a richer merchant than before.
Meantime little Heinel grew up, and as the end of the twelve years drew near the merchant began to call to mind his bond, and became very sad and thoughtful; so that care and sorrow were written upon his face. The boy one day asked what was the matter, but his father would not tell for some time; at last, however, he said that he had, without knowing it, sold him for gold to a little, ugly-looking, black dwarf, and that the twelve years were coming round when he must keep his word. Then Heinel said, 'Father, give yourself very little trouble about that; I shall be too much for the little man.'
When the time came, the father and son went out together to the place agreed upon: and the son drew a circle on the ground, and set himself and his father in
