Diamond seated himself on the other side, and for a while was enraptured with the colour of the air inside the cave. It was a deep, dazzling, lovely blue, deeper than the deepest blue of the sky.
The blue seemed to be in constant motion, like the blackness when you press your eyeballs with your fingers, boiling and sparkling.
But when he looked across to North Wind he was frightened;her face was worn and livid.
"What is the matter with you, dear North Wind?" he said.
"Nothing much. I feel very faint. But you mustn't mind it, for I can bear it quite well. South Wind always blows me faint.
If it were not for the cool of the thick ice between me and her, I should faint altogether. Indeed, as it is, I fear I must vanish."Diamond stared at her in terror, for he saw that her form and face were growing, not small, but transparent, like something dissolving, not in water, but in light. He could see the side of the blue cave through her very heart. And she melted away till all that was left was a pale face, like the moon in the morning, with two great lucid eyes in it.
"I am going, Diamond," she said.
"Does it hurt you?" asked Diamond.
"It's very uncomfortable," she answered; "but I don't mind it, for I shall come all right again before long. I thought I should be able to go with you all the way, but I cannot. You must not be frightened though. Just go straight on, and you will come all right.
You'll find me on the doorstep."
As she spoke, her face too faded quite away, only Diamond thought he could still see her eyes shining through the blue.
When he went closer, however, he found that what he thought her eyes were only two hollows in the ice. North Wind was quite gone;and Diamond would have cried, if he had not trusted her so thoroughly.
So he sat still in the blue air of the cavern listening to the wash and ripple of the water all about the base of the iceberg, as it sped on and on into the open sea northwards. It was an excellent craft to go with the current, for there was twice as much of it below water as above. But a light south wind was blowing too, and so it went fast.
After a little while Diamond went out and sat on the edge of his floating island, and looked down into the ocean beneath him.
The white sides of the berg reflected so much light below the water, that he could see far down into the green abyss. Sometimes he fancied he saw the eyes of North Wind looking up at him from below, but the fancy never lasted beyond the moment of its birth. And the time passed he did not know how, for he felt as if he were in a dream.
When he got tired of the green water, he went into the blue cave;and when he got tired of the blue cave he went out and gazed all about him on the blue sea, ever sparkling in the sun, which kept wheeling about the sky, never going below the horizon. But he chiefly gazed northwards, to see whether any land were appearing.
All this time he never wanted to eat. He broke off little bits of the berg now and then and sucked them, and he thought them very nice.
