"What's your business here?" said the moul guard.

"Ah," said Glurk, "I have brought the prisoners! Har-har-har!"

The guard looked suspiciously at the four of them. "What for?" it said.

Glurk blinked at him.

"Enough of this talking, har-har-har," he said eventually, and hit the guard on the head.

The green eyes went out.

"I runs out of ideas after a while," said Glurk.

Pismire's eyes had grown accustomed to the gloom. It was a big cave, but it didn't look as big as it really ought to have done because of the enormous size of the things in it.

"These are pones, aren't they?" said Brocando.

"Not easy to mistake for anything else. Why are they here?" said Pismire.

"They turns the wheels for the lifting platform," said Glurk. "They're used for all the heavy work. Know something? They're intelligent."

"No, that's just a story," said Pismire airily. "They look bright, I'll grant you, but the head's tiny compared to the body. They've got a brain the size of a dried pea."

"But a very clever dried pea," said Glurk. "I lay low in here last night. They've got a language. All made up of thumps and nose honks. Watch."

A tiny head was lowered towards him out of the shadows, and two bright eyes blinked.

"Er ... if you can understand me, stamp twice," he said hoarsely.

Thud. Thud.

Even Glurk himself looked surprised.

"These are friends. You'll help, OK?"

Thud. Thud.

"That means yes," said Glurk.

"Really?" said Pismire.

"There's his saddle, by the stall."

It was more like a small castle. It had wide girths made of red cloth studded with bronze, and a roof over it, hung with curtains and bells. Inside were cushioned seats, and on the decorated harness was the word 'Acretongue' in tarnished bronze letters.

Pismire sidled closer to the pone while the others were manhandling the saddle, and held up his hand with the fingers spread out.

"How many fingers am I holding up?" he said suspiciously.

Thud. Thud. Thud. Thud.

"Aha! So much for-"

Thud.

"Lucky guess."

The pone lumbered down on to his knees to let them heave the saddle on to his back.

Then he opened his mouth and trumpeted.

It sounded like the creaking of a door, magnified a thousand times-but it waved and changed as well, and seemed to contain a lot of busy little other sounds. Language, thought Pismire. Language without words, but still language.

I wonder if the wights invented that, too? People used to have language without words. We still have. We say "Hmm?" and "Uh" and "Arrgh!", don't we?

What am I thinking? These are animals.

Just very bright ones, perhaps. Very bright indeed.

The other pones raised their heads and answered, with a variety of blasts and trills. Glurk motioned the others up on to Acretongue's back.

"The mouls will have heard that," said Pismire.

"Won't matter," said Glurk. "The pones have decided to go home."

"You mean they could have gone any time?" said Brocando, watching the huge animals leaving their stalls in an orderly line.

"They liked it here when the Vortgorns ran the place," said Glurk. "They likes stuff they find interesting. The mouls don't interest them any more. They don't like them. I think they think we're interesting."

"Now listen, Glurk," said Pismire, "I mean, I'm not saying you're not, you know, quite bright, but I don't think you could have learned a language and all these other things in just a few-"

"Didn't," said Glurk, smirking. "Knew what to expect before I come here."

"How-"

"Enough of this talking, har-har-har," said Glurk. "Tell you later. Be polite, by the way. She said they understand people very well."

"Don't believe it," said Pismire.

One of the pones blew a raspberry in his ear.

"That means they think you're interesting," said Glurk.

"And who's she?" Pismire demanded.

"Tell you soon," said Glurk. He was enjoying himself in a quiet way. For the whole of his life Pismire had known more than he did. It was nice, just for once, to be Mr. Answers.

At the far end of the cave was a thick bronze door. The first two pones walked straight into it, tearing it off its hinges. Once outside the herd broke into a trot, with Acretongue moving up into the lead.

On his trumpeted signal, it became a gallop. It looked ponderous and funny, until you realized that those great big bouncing balls would walk through a house without noticing it.

Up on Acretongue's back the four of them were shaken like small peas in a big pot. Pismire saw a pack of mounted mouls galloping after them, spears ready to throw. Acretongue must have seen them too, because he bellowed like a distressed trumpet.

Three pones detached themselves from the herd and turned. The mouls suddenly realized that they weren't chasing a herd of fleeing animals ...

Pismire stood up in the saddle. "They've gone over them!" he said.

"What, do you mean they jumped?" asked Brocando.

"No! I mean just ... over."

"They hate mouls," said Glurk. "Hate 'em more than any other creatures do. They think they're very uninteresting."

Ahead of them was the archway, surrounded by a milling throng of mouls and Vortgorns. "But all they've got to do is lower that platform and we're done for," shouted Pismire.

"They won't," yelled Glurk, and pointed. "He powers the platform!"

Beside the gateway they noticed for the first time a large treadmill. There was a pone in it. A pack of mouls were attacking it with whips and goads. But it stood stolidly, trumpeting. Acretongue bellowed back.

"They'll rescue it," said Glurk. "By the way-er, what was it-oh, yeah, they hate sharp things even more than mouls, so we got to be careful with spears and things ... "

Some pones hurled themselves towards the mill, tossing mouls aside like dust. Their heavy jaws snapped through the bars. The caged pone shrugged itself free, paused for a moment to stamp on a couple of mouls who had been poking it the hardest, and then leapt through the gateway.

"They must be mad!" said Pismire. "That platform won't hold them!"

"We shall see," said Glurk, as they clattered on to it. The other pones piled on behind them, and Pismire noticed that, though they went out of their way to trample on mouls, they avoided the running Vortgorns. Vortgorns were still a bit interesting.

He expected the platform to split under the weight of the pones. It didn't-quite-but something went clang above them and the remains of the treadmill spun until it was nothing but a blur. The chains shrieked over their pulleys. The wall rushed past. Only Glurk sat calmly. Even Pismire had crouched down in the saddle. They were going to be crushed when they hit the bottom, he knew. Brocando hung on and moaned, with his eyes shut. Even Bane had slumped down, bracing himself for the shock.

So only Glurk saw the pones leaping from the platform, one by one.

The tiny wings opened. They were too small to carry pones-but they worked. They whirled madly and the pones stayed up, drifting gently between the hairs.

With only Acretongue's weight upon it the platform slowed down, and hit the dust with a thud.

Acretongue lumbered off, while all about them pones crashed down through the hairs like falling fruit.

The others looked up at Glurk's face.

"You knew we wouldn't crash!" said Pismire accusingly.

"Hoped," said Glurk. "I wasn't too sure, even after all Culaina said."

"Who's Culaina? Is he the she? said Pismire. He was badly rattled. He was kind enough in his way, but knowing more than Glurk about almost everything was one of the few things he was sure he was good at. He wasn't used to this.

Another pone bounced on to the dust beside them. They're lighter than they look, he thought. Balloons with wings. No wonder they don't like sharp objects ...
