The Long Earth

are ten billion of us, we need ten thousand Earths – but, suddenly, we have them, and more. We have no need of agriculture, to sustain our mighty numbers. Do we have need of cities, then? Of literacy and numeracy, even?’
    But as this vast perturbation of the destiny of mankind continued , it was becoming increasingly clear that there were an awful lot of folks for whom the ambiguous treasures of the Long Earth were for ever out of reach, and they were increasingly unhappy about it.
    And that, fifteen years after Step Day, as she watched Brian Cowley perform with gathering dismay, was what increasingly concerned Monica Jansson.

    THE AIRSHIP STOPPED again, at a barren world, the air just about breathable when Joshua tried it, but stinking of ash under an overcast sky into which the usual sounding-rockets ascended.
    Lobsang said, ‘An aftermath world. Possibly an asteroid strike, but my best guess would be a Yellowstone, maybe a century ago. There may be life in the southern hemisphere, but nature’s clean-up job will take a long time.’
    ‘It’s a wasteland.’
    ‘Of course it is. Earth kills her children over and over again. But the rules are different now. It is a certainty that the volcano under Yellowstone National Park on Datum Earth will become aggressively active in the near future. And what will happen? People will step away. For the first time in human history, such a calamity will be a nuisance rather than a tragedy. Until the sun itself dies there will always be other worlds, and mankind will persist, somewhere in the Long Earth, immune to extinction.’
    ‘I wonder if that’s what the Long Earth is
for
.’
    ‘I’m not yet qualified to comment.’
    ‘Why have we stopped, Lobsang?’
    ‘Because I am picking up a signal on an AM frequency. Rather bad reception. The transmitter is very close. Would you like to see who’s calling?’ Lobsang’s face was a perfect simulation of a grin.
    The airship’s restaurant boasted a pretty good dining table, Joshua had to admit, and certainly better than the makeshift shelf on the observation deck he used when there wasn’t any company. The staple of the meal in front of him was a white meat, the flesh rather fine.
    And he looked up, into the eyes of Sally.
    She had provided the meat. ‘It’s a kind of wild turkey you see around in the local worlds,’ she said now. ‘Good eating if you can be bothered, but they are a prey species and can very nearly outrun a wolf. Sometimes I catch a parcel of them and sell them to the pioneers …’
    For a near-recluse, she did talk a lot, Joshua reflected. But he understood why. Joshua meanwhile just ate, enjoying himself. Maybe he was getting used to the company of women. This woman anyhow.
    Lobsang entered, holding a tray. ‘Orange sorbet. Oranges aren’t native to the New World, but I have brought seeds for planting at suitable locations. Enjoy.’ He served, turned away and disappeared through the blue door.
    Sally had been reasonably polite upon learning the identity and nature of Lobsang. Well, since she’d stopped laughing. Now she lowered her voice. ‘What’s with the Jeeves bit?’
    ‘I think he wants to make you welcome. I knew you’d send a signal, you know.’
    ‘How?’
    ‘Because I would have done in your place. Come on, Sally. You came back to us, and we figure that’s because there’s something you want from us. So let’s trade. You know what we need to learn from you.
How did you get out so far?
’
    She eyed him. ‘I’ll give you a clue. I’m not alone. There are more of us out here than you’d think. Every so often, a stepping box

, you might say. I met a man twenty thousand clicks from the Datum who was certain that he was one jump away from Pasadena, and puzzled by the fact that he couldn’t get home. I led him down to a halfway house and left him there.’
    ‘I always wondered why I kept coming across so many bewildered people. I thought they were just dumb.’
    ‘Possibly many of them were.’
    The voice of Lobsang floated in the air. ‘I am aware of the phenomenon you mention, Sally, and would like to take the opportunity to thank you for giving it a most apposite label.

. But I have been unable to duplicate it.’
    Sally glared at the air. ‘Have you been listening to everything we have been saying?’
    ‘Of course. My ship, my rules. Perhaps you will be good enough to answer Joshua’s question. You’ve given only a partial response; the
