"There are a good many such plants," she said. "The mistletoe we get for Christmas grows on several sorts of trees. Its seed lodges under the bark and sprouts there, just as it would in the ground. Then the wood grows up around the root, and the mistletoe becomes almost a part of the tree. Then there are many kinds of mosses, and the Indian pipe--that white, waxy flower which you found in the woods not long ago, and thought you had found a flowering mushroom. It is a sort of a relation of the mushroom, for it springs from damp, decaying leaves, and has no real root, but it is more of a parasite, for it feeds mainly on roots of living trees and plants. This dodder blooms and drops its seeds to the ground, where they sprout, but as soon as it finds a weed to cling to, the root dies and it lives only on the weed." "Why do they call it love-vine?" asked little Prue. Her mother took the long golden tendril and twined it about her slender white finger. Then she told them the story of V THE PRINCE AND THE THREAD OF GOLD "THERE was once a prince," she began, "who lived in a far country between blue seas. And all the land the prince owned, and a great palace, but he was not happy, because there was a little fisher girl more beautiful than the sunrise, who would not come and dwell in his palace and be his princess. "When this fisher girl saw the prince coming toward her, she would dance away laughing, like a ripple of sunlight on the water, and there were some who said she was not a real child, but a sea-fairy, for she had been found as a babe by the fisher's wife, cast up on the sand, after a great storm. "But the prince did not care whether she was a human being or not. He thought only of her, as each day she grew taller and always more beautiful. He went every morning to the fisher's hut to beg that they would give her to him, and this they would have been glad to do had Dodora been willing, but always she laughed and danced away when they spoke of it, and sometimes they did not see her again until evening. "But one morning, when she was eighteen years old, and they spoke to her, she said, laughing: "'Tell the prince to tie a knot in the thread of love. If he will tie a knot in the thread of love it will hold me fast,' and again she danced away, while her laugh came as the tinkle of the tide among the pebbles on a still evening. "So when the prince came that day they told him, and he went away sadly, for he thought she was only playing with him for her amusement. "But that night, as he walked alone in the moonlight by the shore, he suddenly saw on the sand in front of him a radiant fairy, spinning on a silver spinning-wheel a wonderful thread of gold. Without daring to breathe he stood and looked at her, and then he saw that it was from the rays of moonlight that she was spinning the thread. All at once she rose and came to where he was standing.
