What a day that was! They traced the little river from still pool to singing rapids, and ever about them were the strange twitterings and pipings that were the voices of the flowers. Every turn brought a new vista of beauty; every moment brought a new sense of delight. They talked or were silent; when they were thirsty, the cool river was at hand; when they were hungry, fruit offered itself. When they were tired, there was always a deep pool and a mossy bank; and when they were rested, a new beauty beckoned. The incredible trees towered in numberless forms of fantasy, but on their own side of the river was still the flower-starred meadow. Galatea twisted him a bright-blossomed garland for his head, and thereafter he moved always with a sweet singing about him. But little by little the red sun slanted toward the forest, and the hours dripped away. It was Dan who pointed it out, and reluctantly they turned homeward. As they returned, Galatea sang a strange song, plaintive and sweet as the medley of river and flower music. And again her eyes were sad. "What song is that?" he asked. "It is a song sung by another Galatea," she answered, "who is my mother." She laid her hand on his arm. "I will make it into English for you." She sang: "The River lies in flower and fern, In flower and fern it breathes a song. It breathes a song of your return, Of your return in years too long. In years too long its murmurs bring Its murmurs bring their vain replies, Their vain replies the flowers sing, The flowers sing, 'The River lies!'" Her voice quavered on the final notes; there was silence save for the tinkle of water and the flower bugles. Dan said, "Galatea--" and paused. The girl was again somber-eyed, tearful. He said huskily, "That's a sad song, Galatea. Why was your mother sad? You said everyone was happy in Paracosma." "She broke a law," replied the girl tonelessly. "It is the inevitable way to sorrow." She faced him. "She fell in love with a phantom!" Galatea said. "One of your shadowy race, who came and stayed and then had to go back. So when her appointed lover came, it was too late; do you understand? But she yielded finally to the law, and is forever unhappy, and goes wandering from place to place about the world." She paused. "I shall never break a law," she said defiantly. Dan took her hand. "I would not have you unhappy, Galatea. I want you always happy." She shook her head. "I _am_ happy," she said, and smiled a tender, wistful smile.
