Once upon a time there was a king who had a wife, whose name was Silver-tree, and a daughter, whose name was Gold-tree. On a certain day of the days, Gold-tree and Silver-tree went to a glen, where there was a well, and in it there was a trout.
Said Silver-tree, "Troutie, bonny little fellow, am not I the most beautiful queen in the world?" "Oh! Indeed you are not." "Who then?" "Why, Gold-tree, your daughter." Silver-tree went home, blind with rage. She lay down on the bed, and vowed she would never be well until she could get the heart and the liver of Gold-tree, her daughter, to eat.
At nightfall the king came home, and it was told him that Silver-tree, his wife, was very ill. He went where she was, and asked her what was wrong with her. "Oh! Only a thing which you may heal, if you like." "Oh! Indeed there is nothing at all which I could do for you that I would not do." "If I get the heart and the liver of Gold-tree, my daughter, to eat, I shall be well."
Now it happened about this time that the son of a great king had come from abroad to ask Gold-tree for marrying. The King now agreed to this, and they went abroad. The king then went and sent his lads to the hunting-hill for a he-goat, and he gave its heart and its liver to his wife to eat; and she rose well and healthy.
A year after this Silver-tree went to the glen, where there was the well in which there was the trout. "Troutie, bonny little fellow," said she, " am not I the most beautiful queen in the world?" "Oh! Indeed you are not." "Who then?" "Why, Gold-tree, your daughter." "Oh! Well, it is long since she was living. It is a year since I ate her heart and liver." "Oh! Indeed she is not dead. She is married to a great prince abroad."
Silver-tree went home, and begged the king to put the long-ship in order, and said, "I am going to see my dear Gold-tree, for it is so long since I saw her." The long-ship was put in order, and they went away. It was Silver-tree herself that was at the helm, and she steered the ship so well that they were not long at all before they arrived.
