to yield to this deadly force—and drop!
It was then for the first time he noticed a change had come over the surface of the earth below. Instead of the patchwork of field and wood and road, he saw a vast cloud stretching out, white and smooth in the moonlight. The world was hidden beneath a snowy fog, dense and impenetrable. It was no longer even possible to tell in what direction he was flying, for there was nothing to steer by. This was a new and unexpected complication, and the boy could not understand how the change had come about so quickly; the last time he had glanced down for indications to steer by, everything had been clear and easily visible.
It was very beautiful, this carpet of white mist with the silver moon shining upon it, but it thrilled him now with an unpleasant sense of dread. And, still more unpleasant, was a new sound which suddenly broke in upon the stillness and turned his blood into ice. He was certain that he heard wings behind him. He was being followed, and this meant that it was impossible to turn and fly back.
There was nothing now to do but fly forwards and hope to distance the huge wings; but if he was being followed by the powerful flyer he had seen a few nights before, the boy knew that he stood little chance of success, and he only did it because it seemed the one thing possible.
The cloud was dense and chill as he entered it; its moisture clung to his wings and made them heavy; his muscles seemed to stiffen, and motion became more and more difficult. The wings behind him meanwhile came closer.
He was flying along the surface of the mist now, his body and wings hidden, and his head just above the level. He could see along its white, even top. If he sank a few more inches it would be impossible to see at all, or even to judge where he was going. Soon it rose level with his lips, and at the same time he noticed a new smell in the air, faint at first, but growing every moment stronger. It was a fresh, sweet odour, yet it somehow added to his alarm, and stirred in him new centres of uneasiness. He tried vainly to increase his speed and distance the wings which continued to gain so steadily upon him from behind.
The cloud, apparently, was not everywhere of the same density, for here and there he saw the tops of green hills below him as he flew. But he could not understand why each green hill seemed to have a little lake on its summit—a little lake in which the reflected moon stared straight up into his face. Nor could he quite make out what the sounds were which rose to his ears through the muffling of the cloud—sounds of tumultuous rushing, hissing, and tumbling. They were continuous, these sounds, and once or twice he thought he heard with them a deep, thunderous roar that almost made his heart stop beating as he listened.
Was he, perhaps, over a range of high mountains, and was this the sound of the tumbling torrents?
Then, suddenly, it came to him with a shock that the ordinary sounds of the earth had wholly ceased.
Jimbo felt his head beginning to whirl. He grew weaker every minute; less able to offer resistance to the remorseless forces that were sucking him down. Now the mist had closed over his head, and he could no longer see the moonlight. He turned again, shaking with terror, and drove forward headlong through the clinging vapour. A sensation of choking rose in his throat; he was tired out, ready to drop with exhaustion. The wings of the following creature were now so close that he thought every minute he would be seized from behind and plunged into the abyss to his death.
It was just then that he made the awful discovery that the world below him was not stationary: the green hills were moving. They were sweeping past with a rushing, thundering sound in regular procession; and their huge sides were streaked with white. The reflection of the moon leaped up into his face as each hill rolled hissing and gurgling by, and he knew at last with a shock of unutterable horror that it was THE SEA!
He was flying over the sea, and the waters were drawing him down. The immense, green waves that rolled along through the sea fog, carrying the moon's face on their crests, foaming and gurgling as they went, were already leaping up to seize him by the feet and drag him into their depths.
He dropped several feet deeper into the mist, and towards the sea, terror-stricken and blinded. Then, turning frantically, not knowing what else to do, he struck out, with his last strength, for the upper surface and the moonlight. But as he did so, turning his face towards the sky he saw a dark form hovering just above him, covering his retreat with huge outstretched wings. It was too late; he was hemmed in on all sides.
At that moment a huge, rolling wave, bigger than all the rest, swept past and wet him to the knees. His heart failed him. The next wave would cover him. Already it was rushing towards him with foaming crest. He was in its shadow; he heard its thunder. Darkness rushed over him—he saw the vast sides streaked with grey and white—when suddenly, the owner of the wings plucked him in the back, mid-way between the shoulders, and lifted him bodily out of the fog, so that the wave swept by without even wetting his feet.
The next minute he saw a dim, white sheet of silvery mist at his feet, and found himself far above it in the sweet, clean moonlight; and when he turned, almost dead with terror, to look upon his captor, he found himself looking straight into the eyes of—the governess.
The sense of relief was so great that Jimbo simply closed his wings, and hung, a dead weight, in the air.
"Use your wings!" cried the governess sharply; and, still holding him, while he began to flap feebly, she turned and flew in the direction of the land.
"You!" he gasped at last. "It was you following me!"
"Of course it was me! I never let you out of my sight. I've always followed you—every time you've been out alone."
Jimbo was still conscious of the drawing power of the sea, but he felt that his companion was too strong for it. After fifteen minutes of fierce flight he heard the sounds of earth again, and knew that they were safe.
Then the governess loosened her hold, and they flew along side by side in the direction of home.
"I won't scold you, Jimbo," she said presently, "for you've suffered enough already." She was the first to break the silence, and her voice trembled a little. "But remember, the sea draws you down, just as surely as the moon draws you up. Nothing would please Him better than to see you destroyed by one or the other."
Jimbo said nothing. But, when once they were safe inside the room again, he went up and cried his eyes out on her arm, while she folded him in to her heart as if he were the only thing in the whole world she had to love.
CHAPTER XV
THE CALL OF THE BODY
One night, towards the end of the practice flights, a strange thing happened, which showed that the time for the final flight of escape was drawing near.
They had been out for several hours flying through a rainstorm, the thousand little drops of which stung their faces like tiny gun-shot. About two in the morning the wind shifted and drove the clouds away as by magic; the stars came out, at first like the eyes of children still dim with crying, but later with a clear brilliance that filled Jimbo and the governess with keen pleasure. The air was washed and perfumed; the night luminous, alive, singing. All its tenderness and passion entered their hearts and filled them with the wonder of its glory.
"Come down, Jimbo," said the governess, "and we'll lie in the trees and smell the air after the rain."
"Yes," added the boy, whose Older Self had been whispering mysterious
