The five maids answered, "We want to forget that there are such things as herons in the world!"
After much thought the Queen said to the Fairy, "You have changed a Princess into a heron, and five maids into herons and back again; cannot you change one heron into a Prince?" But the Fairy answered sadly, "Our power has limits; we can bring down, but we cannot bring up, if there be no heart to answer our call. The five maids only followed their hearts, that were human, when I called them back; but a heron has only a heron's heart, and unless his heart become too great for a bird and he earn a human one, I cannot change him to a higher form." "How can he earn a human one?" asked the Queen. "Only if he love the Princess so well that his love for her becomes stronger than his life," answered the Fairy. "Then he will have earned a human body, and then I can give him the form that his heart suits best. There may be a chance, if we wait for it and are patient, for the Princess's love is great and may work miracles."
A little while after this, the Queen watching, saw that the two herons were making a nest among the reeds. "What have you there?" said the mother to her daughter. "A little hollow place," answered the heron-Princess, "and in it the moon lies." A little while after she said again, "What have you there, now, little daughter?" And her daughter answered, "Only a small hollow space; but in it two moons lie."
The Queen told the family Fairy how in a hollow of the reeds lay two moons. "Now," said the Fairy, "we will wait no longer. If your daughter's love has touched the heron's heart and made it grow larger than a bird's, I can help them both to happiness; but if not, then birds they must still remain."
Among the reeds the heron said in bird language to his wife, "Go and stretch your wings for a little while over the water; it is weary work to wait here so long in the reeds." The heron-Princess looked at him with her bird's eyes, and all the human love in her heart strove, like a fountain that could not get free, to make itself known through them; also her tongue was full of the longing to utter sweet words, but she kept them back, knowing they were beyond the heron's power to understand. So she answered merely in heron's language, "Come with me, and I will come!"
They rose, wing beating beside wing; and the reflection of their grey breasts slid out under them over the face of the water.
Higher they went and higher, passing over the tree tops, and keeping time together as they flew. All at once the wings of the grey heron flagged, then took a deep beat; he cried to the heron-Princess, "Turn, and come home, yonder there is danger flying to meet us!" Before them hung a brown blot in the air, that winged and grew large. The two herons turned and flew back. "Rise," cried the grey heron, "we must rise!" and the Princess knew what was behind, and struggled with the whole strength of her wings for escape.
The grey heron was bearing ahead on stronger wing. "With me, with me!" he cried. "If it gets above us, one of us is dead!" But the falcon had fixed his eye on the Princess for his quarry, and flew she fast, or flew she slow, there was little chance for her now. Up and up she strained, but still she was behind her mate, and still the falcon gained.
The heron swung back to her side; she saw the anguish and fear of his downward glance as his head ranged by hers. Past her the falcon went, towering for the final swoop.
The Princess cried in heron's language, "Farewell, dear mate, and farewell, two little moons among the reeds!" But the grey heron only kept closer to her side.
