But as they went through the deep alleys of the garden that led down to the shore they came to a sight more wonderful than anything they had yet seen. Before them, facing toward the sea, stood two great reindeer, their high horns reaching to the overhead boughs; and behind them lay a sledge, long and with deep sides like the sides of a ship. All blue they seemed in that strange light. There too, but nearer to hand, was the moon-fay himself waiting--a great figure of lofty stature, clad in furs of blue fox-skin, and with heron’s wings fastened above the flaps of his hood; and these lifted themselves and clapped as Hands and the Princess drew near. “Are you coming to the blue moon?” called the fay, and his voice whistled and shrewed to them like the voice of a wind. Hands-pansy gave back answer stoutly: “Yes, yes, we are coming!” And indeed what better could he say? “But,” cried Nillywill, holding back for a moment, “what will the blue moon do for us?” “Once you are there,” answered the moon-fay, “you can have your wish and your heart’s desire; but only once in a blue moon can you have it. Are you coming?” “We are coming!” cried Nillywill. “Oh, let us make haste!” “Tread softly,” whispered the moon-fay, “and stoop well under these boughs, for if anything awakes to behold the blue moon, the memory of it can never die. On earth only the nightingale of all living things has beheld a blue moon; and the triumph and pain of that memory wakens him ever since to sing all night long. Tread softly, lest others waken and learn to cry after us; for we in the blue moon have our sleep troubled by those who cry for a blue moon to return.” He looked towards Nillywill, and smiled with friendly eyes. “Come!” he said again, and all at once they had leapt upon the sledge, and the reindeer were running fast down toward the sea. The blue moon was resting with its lower rim upon the waters. At that sight, before they were clear of the avenues of the garden, one of the reindeer tossed up his great branching horns and snorted aloud for joy. With a soft stir in the thick boughs overhead, a bird with a great trail of feathers moved upon its perch. The sledge, gliding from land, passed out over the smoothed waters, running swiftly as upon ice; and the reflection of the stars shone up like glow-worms as Nillywill and Hands-pansy, in the moon-fay’s company, sped away along its bright surface. The still air whistled through the reindeers’ horns; so fast they went that the trees and the hanging gardens and the palace walls melted away from view like wreaths of smoke. Sky and sea became one magic sapphire drawing them in towards the centre of its life, to the heart of the blue moon itself.
