'But can't I go after him?' Lucy persisted.

'I am sorry to say,' said Mr. Noah, 'that we have no boats; the Pretenderette has stolen our one and only Hippogriff, and none of our camels can fly.'

'But what can I do?' Lucy stamped her foot in her agony of impatience.

'Nothing, my child,' Mr. Noah aggravatingly replied, 'except to go to bed and get a good night's rest. To-morrow we will return to the city and see what can be done. We must consult the oracle.'

'But can't we go now,' said Lucy, crying.

'No oracle is worth consulting till it's had its night's rest,' said Mr. Noah. 'It is a three days' journey. If we started now—see it is already dusk—we should arrive in the middle of the night. We will start early in the morning.'

But early in the morning there was no starting from the castle of the Dwellers by the Sea. There was indeed no one to start, and there was no castle to start from.

A young blugraiwee, peeping out of its hole after a rather disturbed night to see whether any human beings were yet stirring or whether it might venture out in search of yellow periwinkles, which are its favourite food, started, pricked its spotted ears, looked again, and, disdaining the cover of the rocks, walked boldly out across the beach. For the beach was deserted. There was no one there. No Mr. Noah, no Lucy, no gentle islanders, no M.A.'s—and what is more there were no huts and there was no castle. All was smooth, plain, bare sea-combed beach.

For the sea had at last risen. The fear of the Dwellers had been justified. Whether the sea had been curious about the ark no one knows, no one will ever know. At any rate the sea had risen up and swept away from the beach every trace of the castle, the huts and the folk who had lived there.

A bright parrot, with a streamer of motor veiling hanging to one claw, called suddenly from the clear air to the little blugraiwee.
