Here the factors were, he thought: the birth rate and the total population of the Earth, the death rate, the values of currencies, the spread of living costs, attendance of places of worship, medical advances, technological developments, industrial indices, the labor market, world trade trends-and many others, including some that at first glance might not seem too relevant: the auction price of art objects, vacation preferences and movements, the speed of transportation, the incidence of insanity.
The statistical method developed by the mathematicians of Mizar, he knew, would work anywhere, on anything, if applied correctly. But he had been forced to twist it in translating an alien planet's situation to fit the situation here on Earth-and in consequence of that twisting, did it still apply?
He shuddered as he looked at it. For if he'd made no mistake, if he'd handled everything correctly, if his translations had done no violence to the concept, then the Earth was headed straight for another major war, for a holocaust of nuclear destruction.
He let loose of the corners of the chart and it rolled itself back into a cylinder.
He reached for one of the fruits the Sirrah being had brought him and bit into it. He rolled it on his tongue, savoring the delicacy of the taste. It was, he decided, as good as that strange, birdlike being had guaranteed it would be.
There had been a time, he remembered, when he had held some hope that the chart based on the Mizar theory might show, if not a way to end all war, at least a way to keep the peace. But the chart had never given any hint of the road to peace. Inexorably, relentlessly, it had led the way to war.
How many other wars, he wondered, could the people of the Earth endure?
No man could say, of course, but it might be just one more. For the weapons that would be used in the coming conflict had not as yet been measured and there was no man who could come close to actually estimating the results these weapons would produce.
War had been bad enough when men faced one another with their weapons in their hands, but in any present war great payloads of destruction would go hurtling through the skies to engulf whole cities-aimed not at military concentrations, but at total populations.
He reached out his hand for the chart again, then pulled it back. There was no further need of looking at it. He knew it all by heart. There was no hope in it. He might study it and puzzle over it until the crack of doom and it would not change a whit. There was no hope at all. The world was thundering once again, in a blind red haze of fury and of helplessness, down the road to war.
He went on with his eating and the fruit was even better than it had been at first bite. "Next time," the being had said, "I will bring you more." But it might be a long time before he came again, and he might never come. There were many of them who passed through only once, although there were a few who showed up every week or so-old, regular travelers who had become close friends.
And there had been, he recalled, that little group of Hazers who, years ago, had made arrangements for extra long stopovers at the station so they could sit around this very table and talk the hours away, arriving laden with hampers and with baskets of things to eat and drink, as if it were a picnic.
But finally they had stopped their coming and it had been years since he'd seen any one of them. And he regretted it, for they'd been the best of companions.
He drank an extra cup of coffee, sitting idly in the chair, thinking about those good old days when the band of Hazers came.
His ears caught the faint rustling and he glanced quickly up to see her sitting on the sofa, dressed in the demure hoop skirts of the 1860s.
"Mary!" he said, surprised, rising to his feet.
She was smiling at him in her very special way and she was beautiful, he thought, as no other woman ever had been beautiful.
"Mary," he said, "it's so nice to have you here."
And now, leaning on the mantelpiece, dressed in Union blue, with his belted saber and his full black mustache, was another of his friends.
"Hello, Enoch," David Ransome said. "I hope we don't intrude."
"Never," Enoch told him. "How can two friends intrude?"
He stood beside the table and the past was with him, the good and restful past, the rose-scented and unhaunted past that had never left him.
Somewhere in the distance was the sound of fife and drum and the jangle of the battle harness as the boys marched off to war, with the colonel glorious in his full-dress uniform upon the great black stallion, and the regimental flags snapping in the stiff June breeze.
He walked across the room and over to the sofa. He made a little bow to Mary.
"With your permission, ma'am," he said.
"Please do," she said. "If you should happen to be busy…"
"Not at all," he said. "I was hoping you would come."
He sat down on the sofa, not too close to her, and he saw her hands were folded, very primly, in her lap. He wanted to reach out and take her hands in his and hold them for a moment, but he knew he couldn't.
For she wasn't really there.
"It's been almost a week," said Mary, "since I've seen you. How is your work going, Enoch?"
He shook his head. "I still have all the problems. The watchers still are out there. And the chart says war."
David left the mantel and came across the room. He sat down in a chair and arranged his saber.
"War, the way they fight it these days," he declared, "would be a sorry business. Not the way we fought it, Enoch."
"No," said Enoch, "not the way we fought it. And while a war would be bad enough itself, there is something worse. If Earth fights another war, our people will be barred, if not forever, at least for many centuries, from the cofraternity of space."
"Maybe that's not so bad," said David. "We may not be ready to join the ones in space."
"Perhaps not," Enoch admitted. "I rather doubt we are. But we could be some day. And that day would be shoved far into the future if we fight another war. You have to make some pretense of being civilized to join those other races."
"Maybe," Mary said, "they might never know. About a war, I mean. They go no place but this station."
Enoch shook his head. "They would know. I think they're watching us.
And anyhow, they would read the papers."
"The papers you subscribe to?"
"I save them for Ulysses. That pile over in the corner. He takes them back to Galactic Central every time he comes. He's very interested in Earth, you know, from the years he spent here. And from Galactic Central, once he'd read them, I have a hunch they travel to the corners of the galaxy."
"Can you imagine," David asked, "what the promotion departments of those newspapers might have to say about it if they only knew their depth of circulation."
Enoch grinned at the thought of it.
"There's that paper down in Georgia," David said, "that covers Dixie like the dew. They'd have to think of something that goes with galaxy."
"Glove," said Mary quickly. "Covers the galaxy like a glove. What do you think of that?"
"Excellent," said David.
"Poor Enoch," Mary said contritely. "Here we make our jokes and Enoch has his problems."
"Not mine to solve, of course," Enoch told her. "I'm just worried by them. All I have to do is stay inside the station and there are no problems. Once you close the door here, the problems of the world are securely locked outside."
"But you can't do that."
"No, I can't," said Enoch.
"I think you may be right," said David, "in thinking that these other races may be watching us. With an eye, perhaps, to some day inviting the human race to join them. Otherwise, why would they have wanted to set up a station here on Earth?"
