'"I shall never get tired of her," she said; "she is my own treasure-trove."
'Nevertheless, during all this time some misgiving, low down in her heart or conscience, made her keep away from the aged sea-lady, who had often in time past reproved her for her thoughtlessness. Why she did so she excused to herself by saying she had no leisure now for anything but care for the little girl.
"And the great-grandmother could not but be pleased if she knew how my time is spent," she would say to herself; "she was always the one to tell me to be of use to others and to be more sedate, and I am certainly now following her counsel." Yet notwithstanding these assurances to herself, she took care that in their playing and gambolling she and the baby should keep away from the cave where dwelt the aged grand-dame.
'So time went on. It passes perhaps more quickly, or its passing is less noticed, down in the under-world of the ocean, than with the dwellers on the land. It seemed to Emerald but a few days since the coming of her little pet, when her happy belief that all was right received a sudden blow. Baby was growing big now, for nearly as much of her life had by this time been spent in the sea as on land, and Emerald had fondly hoped that all remembrance of her own home had faded from the child's mind. The princess arrived one day on a visit to her parents. Emerald had always been a favourite of hers, and meeting her playing in the palace gardens with her little charge, she stopped to speak to them.
'"Ah, Emerald," she said, "so this is the pretty child you saved? I have heard of her. How well you have treasured her, and I, too, have been careful of my treasure." She touched the long golden chain hanging round her neck as she spoke, and playfully tossed it towards the little girl, who caught it, laughing. But as she looked more closely at the golden links in her fingers, a change came over her little face; it grew troubled, and Emerald, fearful lest she should begin to cry, made some excuse to the princess and carried her away, talking merrily as they went. But the child's face did not clear.
'"Emerald," she said, for by this time she could talk quite perfectly, "something has come back to me. I remember that pretty chain. I threw it into the water, when brother was running after me. Oh, Emerald, I want to go home to him and the others. You may come too, dear Emerald, but I must go home."
'Her words sent a thrill of fear through the heart of her young sea-mother.
'"Oh, baby darling," she said, "what has put such fancies in your little head? Are you not happy with Emerald and all your pretty toys and games? Emerald cannot go away from her own country, and she would be too miserable without you. And you—you would cry sadly at night, if she was not there to sing you to sleep."
'And the trouble on the mermaiden's face, as she spoke thus, grieved the little girl, for she had a tender heart. She gently stroked Emerald's cheeks, and said no more for the time. But from that moment, ever and anon, there crept into her soft blue eyes the strange, sad, far-away look which told that the charm was broken. She was pining for her own race and her own land.
'Emerald tried not to see it, tried to persuade herself that the child would be miserable away from the sea country, that it would be cruel to the little creature herself to restore her to her friends. Gradually, however, it became impossible to go on deceiving herself. Baby grew thin and pale—every one noticed it. Though gentle and tender as ever to her mermaid nurse, it was rarely now that her voice was heard in laughter or glee; and her smiles were even sadder than the wistfulness in her face.
