“…Or Lemuria, as we call it,” McCann said.

Nemoto said, “A lost continent beneath the Indian Ocean, once thought to have been the cradle of mankind.”

McCann talked on: of how the dozen men had travelled here; of a disastrous landing that had wrecked their ship and killed three of them; of how they had sent heliograph and radio signals home and waited for rescue — and of how their Earth had flickered out of the sky, to be replaced by another, and another.

“A sheaf of worlds,” murmured Nemoto, gazing at McCann.

When it was clear that no rescue was to come, some of the exploratory party had submitted to despair. One committed suicide. Another handed himself over to a party of Elf-folk for a hideous and protracted death.

The survivors had recruited local Hams, and used their muscles and Runner labour to construct this little township. They had found no others of their kind, save for the sinister-sounding Zealots, of whom McCann was reluctant to speak, who lived some distance from the compound.

It seemed that it had been the mysterious Zealots who had taught the indigenes their broken English — if inadvertently, through escaped slaves returning to their host populations. The Zealots had been here for centuries, McCann seemed to believe.

“Not much of a life,” McCann said grimly. “No women, you see. Some of us sought relief with the Hams, even with Runners. But they aren’t women. And there were certainly no children to follow.” He smiled stoically. “Without women and children, you can’t make a colony, can you? After a time you wonder why you bother to shave every day.”

One by one the Englishmen had died, their neat little huts falling into disrepair.

McCann showed them a row of graves, outside the stockade gate, marked by bits of stone. The last to die had been a man called Jordan— ‘dead of paralytic shock’, McCann said. McCann appeared especially moved to be at Jordan’s grave side. Malenfant wondered if these withdrawn, lonely men, locked in civility and their memories of a forever lost home, had in the end sought consolation in each other.

But McCann, in a gruesome effort to play the good host, talked brightly of better times. “We had a life of sorts. We played cards — until they wore out and we made chess sets, carving pieces from bits of balsa. We had no books, but we would spin each other yarns, recounting the contents of novels as best we remembered them. I dare say the shades of a few authors are restless at the liberties we took. Once or twice we even put on a play or two. Marlowe comedies mostly: Much Ado About Nothing, that kind of thing. Just to amuse ourselves, of course.

“We used to play sports. Your average Ham can’t kick a soccer ball to save his life, but he’s a formidable rugby player. As for the Runners, they can’t grasp the simplest principle of rules or sportsmanship. But, my, can they run! We would organize races. The record we got was under six seconds for the hundred yard dash. That fellow was rewarded with plenty of bananas and beer…”

McCann spoke of how the survivors, just four of them, had become withdrawn, even one from the other, as they waited gloomily for death. Crawford would disappear into the forest for days on end with squads of Hams, “fossicking around’, as McCann put it. The others would rarely even leave their huts.

“And you?” Nemoto asked. “What is your eccentricity, Mr McCann?”

“A longing for company,” he said immediately, smiling with self-deprecation. “That’s always been my weakness, I’m afraid.”

“Then it must have been hard for you here,” Malenfant said.

“Indeed. But when my companions withdrew into themselves, I sought out the company of the lesser folk: the Hams, even the Runners at times. My companions took to calling me Mowgli. Perhaps you know the reference. I have attempted to civilize them, teach them skills — more advanced tool-making, even reading. With little success, I am afraid. Your bar-bar is smarter than your Runner, and these pre-sapients are smarter in turn than the pongid species, the Elves and Nutcrackers. Your bar-bar can be taught to use a new tool, you know — to use it but never to make it. They can make things work but never understand how they work, rather like human infants. And, like your Kaffir, your bar-bar can see the first stage of a thing, and maybe the second, but no more.

“And that, of course, is the difference between man and pre-sapient. Wherever there are sub-men, who live only for the day and their own bellies, we must rule. But the work shapes one. The responsibility. It has made me pitiful and kindly, I would say, as I have learned something of their strange, twisted reasoning.” He leaned towards them. “They have no chins, you see, none of them. And everybody knows that a weak chin generally denotes a weak race.”

When evening came again, fires were built within the palm-thatched huts, and smoke rose through the roofs and the crude chimneys that pierced them. Malenfant saw a pair of bats, flapping uncertainly between the turbulent columns of smoke. They were big, as big as crows, with broad, rounded wings.

“Leaf-nose bats,” Nemoto murmured.

“Don’t tell me. Prehistoric bats.”

Nemoto shrugged. “Perhaps. There are many bats here. They have occupied some of the niches never taken by the birds.”

Malenfant watched the bats” slow, ungainly flapping. “They sure look unevolved.”

“Ah, but they were the peak of aerial engineering when they hunted flies and mosquitoes over lakes full of dinosaurs, Malenfant. You should have a little more respect.”

“I guess I should.”

Nemoto whispered conspiratorially, “It all hangs together, Malenfant.”

“What does?”

“McCann’s account of his alternate Earth. A much larger Moon would raise immense tides. The oceans would not be navigable. McCann’s America must once have been linked to Eurasia by land bridges, as ours was, for otherwise the Hams presumably couldn’t have reached it. But when the land bridges were submerged, the Americas were effectively cut off — until iron-hulled ships and aeroplanes emerged, in the equivalent of our own twentieth century. Malenfant, it may have been easier to fly to the Moon than to reach America. Think of that.”

“What does all this mean, Nemoto?”

“I am working on it,” she said seriously. “Consider this, though. We are alone on our Earth, our closest relatives terribly distant. But McCann’s world has a spectrum of hominid types — as it was on our own Earth, long ago. McCann’s Earth may in some senses be more typical than ours.”

A party of Runners, supervised by a Ham, brought in a couple of deer, slung between them, half-butchered.

“Look at that,” muttered Nemoto. “I think that one is a mouse deer.” It was small, the size of a dog, its coat yellow-brown spotted with white, and it had tusks in its upper jaw. “You see them in Africa. Actually it isn’t really a deer at all. It is midway between pigs and deer, and more primitive than either. It climbs trees. It catches fish in the streams. Probably unchanged across thirty million years. Older than grass, Malenfant.”

“And the other?”

This was a little larger than the mouse deer, with a black stripe down its back, and powerful hind legs: a creature evolved for the undergrowth, Malenfant thought.

“A duiker, I think,” Nemoto said. “Another primitive form, the oldest of the antelopes. Sometimes hunts birds and feeds on carrion. Maybe here it eats bats. Everything is ancient here.” Now she seemed agitated. “Perhaps these forms were brought here by the same mechanism that imported hominids. What do you think?”

“Take it easy.”

Her small, thin face worked in the gathering gloom. “This is wrong, Malenfant.”

“Wrong? What’s wrong with it?”

“The ecology is — out of tune. Like a misfiring engine. It is a jumble of species and micro-ecologies, a mixed-up place, fragments thrown together. Though many of the fragments are very ancient, there has been no time for these plants and animals to evolve together, to find an equilibrium. Periodically something disturbs this world, Malenfant, over and over, stirring it up.”
