Terry Pratchett - The Long Earth

‘Look down.’

On the outcrop to which they were anchored, black rock protruding through the snow, stood a natural monument: a lonesome pine, big, elderly and isolated. But the tree had been neatly cut down close to the root, the tangled branches and the upper trunk lying discarded on the ground, and a pale disc of core wood exposed to the air. An axe had evidently been used.

‘I thought you might be drawn to that sign of humanity. And, Joshua, the second reason: it’s time to try out my backup ambulatory unit.’

Joshua glanced around the gondola. ‘Which is?’

‘You.’

A trunk held the gear. On his chest he was to wear a lightweight pack which contained a facemask and an emergency oxygen supply, a first-aid kit, a flashlight, a gun of some non-ferric metal, a length of very fine rope, other items. On his back would go a canvas pack containing an enigmatic module in a hard, robust, sealed case. He would wear an old-fashioned-looking bluetooth-type earpiece to talk to Lobsang, but he suspected the gear contained other speakers and microphones.

He went back to his stateroom, returned in his bulky Pillsbury gear, and hauled on the backpack. ‘This damn thing’s heavy.’

‘You’ll wear it at all times outside the ship.’

‘And inside the sealed module in the backpack is?’

‘Me,’ Lobsang said shortly. ‘Or a remote unit. Call it a backup. As long as the airship survives, the pack will stay synched with the main processors aboard. If the airship is lost the pack will host my memory until you can get home.’

Joshua laughed. ‘You’ve wasted your money, Lobsang. In what circumstances do you imagine this will be useful? Far enough out, if the airship is lost, neither of us is going home.’

‘It never hurts to plan for all conceivable contingencies. You are my ultimate failsafe, Joshua. That’s why you’re here. Anyhow your kit isn’t complete yet.’

Joshua looked into the trunk again, and pulled out another gadget. It was a framework bristling with lenses, microphones, other sensors, sitting atop a shoulder unit. ‘You have got to be kidding me.’

‘It’s lighter than it looks. The sensor bus should strap securely on your shoulder, and there’s a data feed that plugs into the backpack—’

‘You’re expecting me to explore Earth Million with this parrot on my shoulder?’

Lobsang sounded offended. ‘Parrot it is, if you must… I didn’t expect vanity from you, Joshua. Who’s going to see you? Besides, it’s very practical. I’ll see what you see, hear what you hear; we’ll be in constant touch. And if you have trouble—’

‘What will it do, lay an egg?’

‘Just wear it, please, Joshua.’

It fitted snugly on Joshua’s right shoulder, and was as lightweight as Lobsang had promised. But Joshua knew he was never going to be able to forget the thing was there, that Lobsang was literally at his shoulder with every breath. The hell with it. He hadn’t expected this trip to be a joyride anyhow, and the parrot hardly made it any worse. Besides, the thing would probably break down soon enough.

Without further conversation Joshua went down to an access deck, pulled the door open against the cabin’s slight overpressure — the air pressure was kept high to ensure no external atmosphere could enter the ship until Lobsang had tested it for safety — and stepped into a small elevator cage. A winch lowered him smoothly to the ground, beside the rocky outcrop.

Once on the ground, knee deep in snow, he took a deep breath of the air of this cold Earth, and turned slowly around. The sky had clouded over now, and there was a translucent quality to the air: snow threatening. ‘I take it you’re seeing this. Standard-issue snowfield.’

Lobsang whispered in his ear. ‘I see it. You know, the parrot has nose filters which would enable me to smell—’

‘Forget it.’ Joshua took a few paces, turned and surveyed the airship. ‘Can you see this? Just giving you a chance to check for wear and tear.’

‘Good thinking,’ murmured the parrot.

Joshua knelt beside the tree. ‘There are little flags, marking the trunk rings.’ He plucked one, and picked out the lettering. ‘University of Krakow. Scientists did this. What’s the point?’

‘For climate records from the tree rings, Joshua. Just like on the Datum. Interestingly, such records suggest the split between neighbouring worlds is usually around fifty years deep. Within the lifetime of your average pine tree. Of course that raises a lot of questions.’

Joshua heard a rumble, a splashing sound, a kind of shrill trumpet. He turned slowly; evidently he wasn’t alone on this world. A short distance inland he glimpsed a scene of predator and prey: a cat-like creature with fangs so heavy it could barely lift its head, it seemed, was tracking a waddling beast with a hide like a tank. These were the first animals he had seen on this world.

Lobsang saw what he saw. ‘The over-armed in pursuit of the over-armoured: the result of an evolutionary arms race. And one that has played out on Datum Earth many times, in various contexts, until both parties succumbed to extinction, all the way back to the dinosaur age and beyond. A universal, it seems. As on the Datum, so on the Long Earth. Joshua, go around the rocky outcrop. You’ll come to the open water.’

Joshua turned and walked easily around the outcrop. The snow was deep, heavy to push through, but it felt good to stretch his legs after so many hours in the gondola.

The expanse of the lake opened up before him. On the lake itself ice lay in a sheet, but there was open water close to the shore, and here there was movement, massive, graceful: elephants, a family of them, furry adults with calves between their towering legs. Some of them were wading out into the shallow water. The adults had extraordinary shovel-shaped tusks that they used to scoop at the lake bed, muddying the water for yards around. In a crystalline sparkle of spray a mother played with a calf. Fresh snow started to fall now, big heavy flakes that settled on the fur of the oblivious elephantids.

‘Gompotheres,’ Lobsang murmured. ‘Or relatives, or descendants. I’d keep away from the water. I suspect there are crocodiles.’

Joshua felt oddly moved by the scene; there was a sense of calm about these massive creatures. ‘This is what you brought us down to see?’

‘No. Although these worlds are full of elephant types. A plethora of pachyderms. I wouldn’t normally have brought them to your attention. But they are a high-order prey species, and it appears that they are being tracked. And, interestingly, so are you.’

Joshua stood quite still. ‘Thank you for sharing.’ He looked around, peering through the thickening snow, but saw nothing else moving. ‘Just tell me when to run, OK? I don’t mind if you say right now …’

‘Joshua, the creatures moving cautiously towards you are holding a conversation about you, though I doubt very much if you can hear it because it is very high pitched. Your fillings might tingle.’

‘I have no fillings. I always brushed my teeth properly.’

‘Of course you did. The communication is also quite complex, and becoming more rapid, as if some kind of conclusion is being reached as to what they’re going to do. It comes and goes because they are constantly stepping. This is almost too fast to see — too fast for you to see. From this behaviour I can deduce that they have a very ingenious method of triangulating the point at which all of their major hunters will surround the victim, which is to say, you —’

‘Hold on. Rewind. You said they are stepping ? Stepping animals, stepping predators?’ The world pivoted around Joshua. ‘Well, that’s new.’
