The Last Continent (Discworld 22)

'Lots of bees, though,' said Ridcully. 'But only one swarm,' said Ponder. 'Millions of beetles,' said the Dean. 'I don't think I've seen two alike, sir.'

'Well, that's interesting,' said Ridcully, 'but I don't see—'

'One of anything doesn't work, sir,' said Ponder. 'It can't breed.'

'Yes, but they're only trees, Stibbons.'

'Trees need males and females too, sir.'

'They do?'

'Yes, sir. Sometimes they're different bits of the same tree, sir.'

'What? You sure?'

'Yes, sir. My uncle grew nuts, sir.'

'Keep it down, boy, keep it down! Mrs Whitlow might hear you!' Ponder was taken aback. 'What, sir? But . . . well . . . she is Mrs Whitlow, sir . . .'

'What's that got to do with the price of feet?'

'I mean . . . presumably there was a Mr Whitlow, sir?' Ridcully's face went wooden for a moment and his lips moved as he tried out various responses. Finally he settled, weakly, for: 'That's as maybe, but it all sounds pretty mucky to me.'

'I'm afraid that's nature for you, sir.'

'I used to like walking through the woods on a nice spring morning, Stibbons. You mean to say the trees were at it like knives the whole time?' Ponder's horticultural knowledge found itself a little exhausted at this point. He tried to remember what he could about his uncle, who'd spent most of his life up a ladder. 'I, er, think camel-hair brushes are sometimes involved—' he began, but Ridcully's expression told him that this wasn't a welcome fact, so he went on, 'Anyway, sir, ones don't work. And there's another thing, sir. Who smokes the ciga rettes? I mean, if the bush just hopes that butts are going to be dropped around the place, who does it think is going to smoke them?'

'What?' Ponder sighed. The point about fruit, sir, is that it's a kind of lure. A bird'll eat the fruit and then, er, drop the seeds somewhere. It's the way the plant spreads its seeds around. But we've only seen birds and a few lizards on this island, so how—'

'Ah, I see what you mean,' said Ridcully. 'You're thinking: what kind of bird stops flyin' around for a quick smoke?'

'A puffin,' said the Bursar. 'Glad to see you're still with us, Bursar,' said Ridcully, without looking round. 'Birds don't smoke, sir. You've got to ask yourself what's in it for the bush, you see? If there were people here, well, I suppose you might get a sort of nicotine tree eventually, because they'd smoke the cigarettes – I mean,' he corrected himself, because he prided himself on his logical thought, 'these things that look like cigarettes, and stub them out around the place, thus spreading the seeds which are in the filter. Some seeds need heat to germinate, sir. But if there aren't any people, the bush doesn't make any sense.'

'We're people,' said the Dean. 'And I like a smoke after supper. Everyone knows that.'

'Yes, but with respect, sir, we've only been here a couple of hours and I doubt whether the news has spread all the way to small islands,' said Ponder patiently, and with, as it turned out, one hundred per cent inaccuracy. That's probably not long enough for one to evolve.'

'Are you tellin' me', said Ridcully, like a man with something on his mind, 'that you think when you eat an apple you're helping it to . . .' He stopped. 'It was bad enough about the trees.' He sniffed. 'I shall stick to eating fish. At least they make their own arrangements. At a decent distance, I understand. And you know what I think about evolution, Mister Stibbons. If it happens, and frankly I've always considered it a bit of a fairy story, it has to happen fast. Look at lemmings, for one thing.'

'Lemmings, sir?'

'Right. The little blighters keep chargin' over cliffs, right? And how many have ever changed into birds on the way down, eh? Eh?'

'Well, none, of cou—'

'There's my point,' said Ridcully triumphantly. 'And it's no good one of them on the way down thinking, “Hey, maybe I should waggle my claws a bit,” is it? No, what it ought to do is decide really positively about growing some real wings.'

'What, in a couple of seconds? While they're plunging towards the rocks?'

'Best time.'

'But lemmings don't just turn into birds, sir!'

'Lucky for them if they could, though, eh?' There was a roar, far off in the little jungle. It sounded rather like a foghorn. 'Are you sure there aren't any dangerous creatures on this island?' said the Dean. 'I think I saw some prawns,' said the Senior Wrangler nervously.

'No, the Archchancellor was right, it's far too small,' said Ponder, trying to dismiss the thought of flying lemmings. 'It couldn't possibly support anything that could hurt us, sir. After all, what would it eat?' Now they could all hear something crashing through the trees. 'Us?' said the Dean hesitantly. A creature blundered out on to the sunset sands. It was large and seemed to be mainly head – one huge, reptilian head that looked almost as big as the body below it. It walked on two long hind legs. There was a tail, but given the amount of teeth now showing at the other end the wizards weren't inclined to take in too much additional detail. The creature sniffed the air and roared again. 'Ah,' said Ridcully. 'The solution to the mystery of the disappearing geographer, I suspect. Well done, Senior Wrangler.'

'I think I'll just—' the Dean began. 'Stay still, sir!' hissed Ponder. 'A lot of reptiles can't see you if you don't move!'
