And with that they ran down the slope to the lake.
"Jump!" he cried, and they jumped, and the water splashed up round three white, gleaming shapes.
"Of course you can," said Phœbus. "Now three times round the lake, and then make for the island."
Side by side the three swam, Phœbus swimming gently to keep pace with the children. Their marble clothes did not seem to interfere at all with their swimming, as your clothes would if you suddenly jumped into the basin of the Trafalgar Square fountains and tried to swim there. And they swam most beautifully, with that perfect ease and absence of effort or tiredness which you must have noticed about your own swimming--in dreams. And it was the most lovely place to swim in; the water-lilies, whose long, snaky stalks are so inconvenient to ordinary swimmers, did not in the least interfere with the movements of marble arms and legs. The moon was high in the clear sky-dome. The weeping willows, cypresses, temples, terraces, banks of trees and shrubs, and the wonderful old house, all added to the romantic charm of the scene.
"This is the nicest thing the ring has brought us yet," said Mabel, through a languid but perfect side-stroke.
"I thought you'd enjoy it," said Phœbus kindly; "now once more round, and then the island."
[Illustration: SIDE BY SIDE THE THREE SWAM.]
They landed on the island amid a fringe of rushes, yarrow, willow-herb, loose-strife, and a few late, scented, powdery, creamy heads of meadow-sweet. The island was bigger than it looked from the bank, and it seemed covered with trees and shrubs. But when, Phœbus leading the way, they went into the shadow of these, they perceived that beyond the trees lay a light, much nearer to them than the other side of the island could possibly be. And almost at once they were through the belt of trees, and could see where the light came from. The trees they had just passed among made a dark circle round a big cleared space, standing up thick and dark, like a crowd round a football field, as Kathleen remarked.
First came a wide, smooth ring of lawn, then marble steps going down to a round pool, where there were no water-lilies, only gold and silver fish that darted here and there like flashes of quicksilver and dark flames. And the enclosed space of water and marble and grass was lighted with a clear, white, radiant light, seven times stronger than the whitest moonlight, and in the still waters of the pool seven moons lay reflected. One could see that they were only reflections by the way their shape broke and changed as the gold and silver fish rippled the water with moving fin and tail that steered.
