But as it had been in the Air, so it was in the Sea! When the Queen of the Ocean Fairies saw Butterfly’s dirty brown wings, she and all her Court waved their wands and disappeared. And Butterfly was left alone in the Sea-Palace.

“How beautiful it is!” cried she. “Giants must have made these coral pillars!” As she spoke her eyes were nearly blinded by a swarm of tiny insects, and she saw them rest on an unfinished coral pillar. While she looked and wondered, she heard a thousand shell-trumpets being blown, and many voices singing:—

Mite by mite the insect builds the coral bower!

The sounds drew nearer and nearer, and a hundred Fairies, standing in beautiful shells, came floating through the water. In the largest shell of all was their Queen in a robe of wave-coloured silk spun by the Ocean silkworm. It was as thin as a spider’s web, and the border was gracefully wrought with seed pearls.

“Foolish Butterfly,” said the Queen, “learn to be industrious. We allow no idlers at our Court. Look at the coral pillars of my palace. They were made by these swarms of little creatures. Labour and patience did it all.”

And she waved her wand, and the hundred shells floated away, while all the Fairies sang:—

Mite by mite the insect builds the coral bower!

“Well!” said Butterfly, sighing. “All creatures are busy, on the earth, in the air, and under the water. All things seem happy at their work. Perhaps I can learn to be so, too. I will make the diamond. And it shall be as pure and brilliant as a sunbeam in a water-drop!”

So Butterfly sought the Green Cavern in the Island of Ceylon. Day by day she worked as busily as the coral insects. She grew cheerful and happy. Her wings once more became a splendid green, and the silver spots were so bright that they seemed like sparks of fire. Never had she been so beautiful, never so much loved by the little birds and flowers.

After seven years had passed by, Butterfly knelt at the feet of her Queen and offered her diamond. It gave light like a star, and the whole Fairy Mound shone with its rays. And to this day the Fairies call it “Butterfly’s Diamond.”
