there like a bit of wrecked ship's anchor, and it's beastly hot in the Australian hole."

The others agreed, but Anthea went on digging. She always liked to finish a thing when she had once begun it. She felt it would be a disgrace to leave that hole without getting through to Australia.

The cave was disappointing, because there were no shells, and the wrecked ship's anchor turned out to be only the broken end of a pick-axe handle, and the cave party were just making up their minds that sand makes you thirstier when it is not by the seaside, and someone had suggested that they all go home for lemonade, when Anthea suddenly screamed—

"Cyril! Come here! Oh, come quick—It's alive! It'll get away! Quick!"

They all hurried back.

"It's a rat, I shouldn't wonder," said Robert. "Father says they infest old places—and this must be pretty old if the sea was here thousands of years ago"—

"Perhaps it is a snake," said Jane, shuddering.

"Let's look," said Cyril, jumping into the hole. "I'm not afraid of snakes. I like them. If it is a snake I'll tame it, and it will follow me everywhere, and I'll let it sleep round my neck at night."

"No, you won't," said Robert firmly. He shared Cyril's bedroom. "But you may if it's a rat."

Anthea suddenly screamed, "It's alive!"

"Oh, don't be silly!" said Anthea; "it's not a rat, it's much bigger. And it's not a snake. It's got feet; I saw them; and fur! No—not the spade. You'll hurt it! Dig with your hands."

"And let it hurt me instead! That's so likely, isn't it?" said Cyril, seizing a spade.

"Oh, don't!" said Anthea. "Squirrel, don't. I—it sounds silly, but it said something. It really and truly did"—

"What?"

"It said, 'You let me alone.'"

But Cyril merely observed that his sister must have gone off her head, and he and Robert dug with spades while Anthea sat on the edge of the hole, jumping up and down with hotness and anxiety. They dug carefully, and presently everyone could see that there really was something moving in the bottom of the Australian hole.

Then Anthea cried out, "I'm not afraid. Let me dig," and fell on her knees and began to scratch like a dog does when he has suddenly remembered where it was that he buried his bone.

"Oh, I felt fur," she cried, half laughing and half crying. "I did indeed! I did!" when suddenly a dry husky voice in the sand made them all jump back, and their hearts jumped nearly as fast as they did.

"Let me alone," it said. And now everyone heard the voice and looked at the others to see if they had heard it too.

"But we want to see you," said Robert bravely.

"I wish you'd come out," said Anthea, also taking courage.

"Oh, well—if that's your wish," the voice said, and the sand stirred and spun and scattered, and something brown and furry and fat came rolling out into the hole, and the sand fell off it, and it sat there yawning and rubbing the ends of its eyes with its hands.

"I believe I must have dropped asleep," it said, stretching itself.

The children stood round the hole in a ring, looking at the creature they had found. It was worth looking at. Its eyes were on long horns like a snail's eyes, and it could move them in and out like telescopes; it had ears like a bat's ears, and its tubby body was shaped like a spider's and covered with thick soft fur; its legs and arms were furry too, and it had hands and feet like a monkey's.

"What on earth is it?" Jane said. "Shall we take it home?"

The thing turned its long eyes to look at her, and said—

"Does she always talk nonsense, or is it only the rubbish on her head that makes her silly?"

It looked scornfully at Jane's hat as it spoke.

"She doesn't mean to be silly," Anthea said gently; "we none of us do, whatever you may think! Don't be frightened; we don't want to hurt you, you know."

"Hurt me!" it said. "Me frightened? Upon my word! Why, you talk as if I were nobody in particular." All its fur stood out like a cat's when it is going to fight.

"Well," said Anthea, still kindly, "perhaps if we knew who you are in particular we could think of something to say that wouldn't make you angry. Everything we've said so far seems to have done so. Who are you? And don't get angry! Because really we don't know."

"You don't know?" it said. "Well, I knew the world had changed—but—well, really—Do you mean to tell me seriously you don't know a Psammead when you see one?"

"A Sammyadd? That's Greek to me."

"So it is to everyone," said the creature sharply. "Well, in plain English, then, a Sand-fairy. Don't you know a Sand-fairy when you see one?"

It looked so grieved and hurt that Jane hastened to say, "Of course I see you are, now. It's quite plain now one comes to look at you."

"You came to look at me, several sentences ago," it said crossly, beginning to curl up again in the sand.

"Oh—don't go away again! Do talk some more," Robert cried. "I didn't know you were a Sand-fairy, but I knew directly I saw you that you were much the wonderfullest thing I'd ever seen."

The Sand-fairy seemed a shade less disagreeable after this.

"It isn't talking I mind," it said, "as long as you're reasonably civil. But I'm not going to make polite conversation for you. If you talk nicely to me, perhaps I'll answer you, and perhaps I won't. Now say something."

Of course no one could think of anything to say, but at last Robert thought of "How long have you lived here?" and he said it at once.

"Oh, ages—several thousand years," replied the Psammead.

"Tell us about it. Do."

"It's all in books."

"You aren't!" Jane said. "Oh, tell us everything you can about yourself! We don't know anything about you, and you are so nice."

The Sand-fairy smoothed his long rat-like whiskers and smiled between them.

"Do please tell!" said the children all together.

It is wonderful how quickly you get used to things, even the most astonishing. Five minutes before, the children had had no more idea than you had that there was such a thing as a Sand-fairy in the world, and now they were talking to it as though they had known it all their lives.

It drew its eyes in and said—

"How very sunny it is—quite like old times! Where do you get your Megatheriums from now?"

"What?" said the children all at once. It is very difficult always to remember that "what" is not polite, especially in moments of surprise or agitation.

"Are Pterodactyls plentiful now?" the Sand-fairy went on.

The children were unable to reply.

"What do you have for breakfast?" the Fairy said impatiently, "and who gives it to you?"

"Eggs and bacon, and bread and milk, and porridge and things. Mother gives it to us. What are Mega-what's-its-names and Ptero-what-do-you-call-thems? And does anyone have them for breakfast?"

"Why, almost everyone had Pterodactyl for breakfast in my time! Pterodactyls were something like crocodiles and something like birds—I believe they were very good grilled. You see, it was like this: of course there were heaps of Sand-fairies then, and in the
