But he was also skilled in languages and in practical geography. He could shout ‘help!' in fourteen languages and scream for mercy in a further twelve. He had passed through many of the countries on the Disc, some of them at high speed, and during the long, lovely, boring hours when he'd worked in the Library he'd whiled away the time by reading up on all the exotic and faraway places he'd never visited. He remembered that at the time he'd sighed with relief that he'd never have to visit them.

And, now, here he was.

Jungle surrounded him. It wasn't nice, interesting, open jungle, such as leopard-skin-clad heroes might swing through, but serious, real jungle, jungle that towered up like solid slabs of greenness, thorned and barbed, jungle in which every representative of the vegetable kingdom had really rolled up its bark and got down to the strenuous business of outgrowing all competitors. The soil was hardly soil at all, but dead plants on the way to composthood; water dripped from leaf to leaf, insects whined in the humid, spore-laden air, and there was the terrible breathless silence made by the motors of photosynthesis running flat out. Any yodelling hero who tried to swing through that lot might just as well take his chances with a bean-slicer.

"How do you do that?" said Eric.

"It's probably a knack," said Rincewind.

Eric subjected the wonders of Nature to a cursory and disdainful glance.

"This doesn't look like a kingdom," he complained. "You said we could go to a kingdom. Do you call this a kingdom?"

"This is probably the rain forests of Klatch," said Rincewind. "They're stuffed full of lost kingdoms."

"You mean mysterious ancient races of Amazonian princesses who subject all male prisoners to strange and exhausting progenitative rites?" said Eric, his glasses beginning to fog.

"Haha," said Rincewind stonily. "What an imagination the child has."

"Wossname, wossname, wossname!" shrieked the parrot.

"I've read about them," said Eric, peering into the greenery. "Of course, I own those kingdoms as well." He stared at some private inner vision. "Gosh," he said, hungrily.

"I should concentrate on the tribute if I was you," said Rincewind, setting off down what was possibly a path.

The brightly-coloured blooms on a tree nearby turned to watch him go.

In the jungles of central Klatch there are, indeed, lost kingdoms of mysterious Amazonian princesses who capture male explorers for specifically masculine duties. These are indeed rigorous and exhausting and the luckless victims do not last long.

There are also hidden plateaux where the reptilian monsters of a bygone epoch romp and play, as well as elephants' graveyards, lost diamond mines, and strange ruins decorated with hieroglyphs the very sight of which can freeze the most valiant heart. On any reasonable amp there's barely room for the trees.

The few explorers who have passed on a number of handy hints to those who follow after, such as: 1) avoid if possible any hanging-down creepers with beady eyes and a forked tongue at one end; 2) don't pick up any orange-and-black-stripped creepers that are apparently lying across the path, twitching, because there is often a tiger on the other end; and 3) don't go.

If I'm a demon, Rincewind thought hazily, why is everything stinging me and trying to trip me up? I mean, surely I can only be harmed by a wooden dagger through my heart? Or do I mean garlic?

Eventually the jungle opened out into a very wide, cleared area that stretched all the way to a distant blue range of volcanoes. The land fell away below them to a patchwork of lakes and swampy fields, here and there punctured by great stepped pyramids, each one crowned with a thin plume of smoke curling into the dawn air. The jungle track opened out into a narrow, but paved, road.

"Where's this demon?" said Eric.

"It looks like one of the Tezuman kingdoms," said Rincewind. "They're ruled over by the Great Muzuma, I think."

"She's an Amazonian princess, is she?"

"Strangely enough, no. You'd be astonished how many kingdoms aren't ruled by Amazonian princesses, Eric."

"It looks pretty primitive, anyway. A bit Stone Age."

"The Tezuman priests have a sophisticated calendar and an advanced horology," quoted Rincewind.

"Ah," said Eric, "Good."

"No," said Rincewind patiently. "It means time measurement."

"Oh."

"You'd approve of them. They're superb mathematicians, apparently."

"Huh," said Eric, blinking solemnly. "Shouldn't think they've got a lot to count in a backward civilisation like this."

Rincewind eyed the chariots that were heading rapidly towards them.

"I think they usually count victims," he said.

The Tezuman Empire in the jungle valleys of central Klatch is known for its organic market gardens, its exquisite craftsmanship in obsidian, feathers and jade, and its mass human sacrifices in honour of Quezovercoatl, the Feathered Boa, god of mass human sacrifices. As they said, you always knew where you stood with Quezovercoatl. It was generally with a lot of people on top of a great stepped pyramid with someone in an elegant feathered head-dress chipping an exquisite obsidian knife for your very own personal use.

The Tezuman are renowned on the continent for being the most suicidally gloomy, irritable and pessimistic people you could ever hope to meet, for reasons that may soon be made clear. It was true about the time measurement as well. The Tezuman had realised long ago that everything was getting worse and, having a terrible literal-mindedness, had developed a complex system to keep track of how much worse each succeeding day was.

Contrary to general belief, the Tezumen did invent the wheel. They just had radically different ideas about what you used it for.

It was the first chariot that Rincewind had ever seen that was pulled by llamas. That wasn't what was odd about it. What was odd about it was that it was being carried by people, two holding each side of the axle and running after the animals, their sandalled feet flapping on the flagstones.

"Do you think it's got the tribute in it?" said Eric.

All the leading chariot seemed to contain, apart from the driver, was a squat, basically cube-shaped man wearing a puma-skin outfit and a feather head-dress.

The runners panted to a halt, and Rincewind saw that each man wore what would probably be described as a primitive sword, made by affixing shards of obsidian into a wooden club. They looked to him no less deadly than sophisticated, extremely civilised swords. In fact they looked worse.

"Well?" said Eric.

"Well what?" said Rincewind.

"Tell him to give me my tribute."

The fat man got down ponderously, marched over to Eric and, to Rincewind's extreme surprise, grovelled.

Rincewind felt something claw its way up his back and onto his shoulder, where a voice like a sheet of metal being torn in half said, "That's better. Very wossname, comfy. If you try and knock me off, demon, you can wossname your ear goodbye. What a turn up for the scrolls, eh? They seemed to be expecting him."

"Why do you keep saying wossname?" said Rincewind.

"Limited wossname. Doodah. Thingy. You know. It's got words in it," said the parrot.

"Dictionary?" said Rincewind. They passengers in the other chariots had got out and were also grovelling to Eric, who was beaming like an idiot.

The parrot considered this.

"Yeah, probably," it said. "I've got to wing it to you," it went on. "I thought you were a bit of a wossname at the start, but you seem to be delivering the wossname."

"Demon?" said Eric, airily.

"Yes?"

"What are they saying? Can't you speak their language?"

"Er, no," said Rincewind. "I can read it, though," he called out, as Eric turned away. "If you could just sort of make signs for them to write it down..."
