“Or you might sit down under one of the trees whose branches came to the ground like the weeping ash at home, or you might climb up into another--but no matter how, if you took hold of the leaves and turned them aside, so that the light of the opal sun came through, you could read a magic secret on every one, and it would take you fifty years to read one tree. Some of the leaves strewed the footpath, and some lay on the grass, and some floated on the water, but they did not decay, and the one he held in his hand went throb, throb, like the pulse in your wrist. “And from secret to secret you might wander, always a new secret, till you went beyond the horizon, and then there was another horizon, and after that another, and you could go on and on, and on, and though you could walk for ever without weariness, because the air was so pure and delicious, still you could never, never, never get to the other side. “Some have been walking there these millions of years, and some have been sitting up in the trees, and some have been lying under the golden dome flowers all that time, and never found and never will find the other side, which is why they are so happy. They do not sleep, because they never feel sleepy; they just turn over from the opal sun and look up at the stars and then the music begins, and as it plays they become strong, and then they go on again gathering more of the leaves, and travelling towards the opal sun, and the nearer they get the happier they are, and yet they can never get to it. “While he looked he felt as if he must get through and go on too, and he struggled and struggled, but the bronze door was hard and the wall hard, so that it was no use. His mind though and soul had gone through; and he saw a white shoulder, like alabaster, pure, white, and transparent among the grass by the golden dome flower, and a white arm stretched out towards him, so white it gleamed polished, and a white hand, soft, warm-looking, delicious, transparent white, beckoning to him. So he struggled and struggled till it seemed as if he would get through to his soul, which had gone on down the footpath, when the aged man behind dragged him back, and the bronze door shut with an awful resonance--” “What was that?” “Hark!” “Hark!” Mark seized his spear; Bevis his bow. “Is it something coming from the wave?” “No, it’s in the sky.” “Listen!” There was a whirr above like wheels in the air, and a creaking sound with it. They stood up, but could not see what it was, though it grew louder and came nearer with a rushing noise. Suddenly something white appeared above the trees which had concealed its approach, and a swan passed over descending. It was the noise of its wings and their creaking which sounded like wheels. The great bird descended aslant quite a quarter of a mile into the water to the south in front of them, and there floated among the glittering ripples. “I thought it was the roc,” said Mark, sitting down again.
