The Second Murray Leinster Megapack (114 page)

“They were an experiment,” Sandy told her, “to see if they would content men on duty in an outpost. It’d been going on for only a few hundred years. It didn’t seem to work too well. They wanted supplies that weren’t exactly military, and at the time the cube I used was made, there was trouble getting even military things!”

Burke said impatiently, “I’ll get one of these things to Keller. That’s the most important thing. Tell Holmes not to try to sleep. Take him down to look over the supplies, if there are any. I’d guess that the garrison took most of them along. I doubt there’s much left that we could use.”

He made his way out of the cube-library and vanished.

Pam said uncomfortably, “Joe dreamed about a woman and is no good to you, in consequence. If there were women in this garrison, using the cubes might make anybody—”

Sandy tensed her lips.

“I don’t think Joe is thinking about his old dream. Something deadly’s on the way here. His mind’s on that. I suspect all three of the men are concentrating on it. They’re in no mood for romance.”

“Don’t you think I’ve noticed?” Pam said gloomily. “But I’m coming with you when you show him the storerooms!”

The “him” was obviously Holmes, whose attention had been so much taken up by the problems the fortress presented that Pam felt pushed much farther on the side lines than she liked. It was one thing to be present to watch and help and cheer on a man who planned to do something remarkable. But it was less satisfying when he became so absorbed that he didn’t notice being watched, and couldn’t be helped, and didn’t need to be cheered on. Pam was disgruntled.

Then, for a considerable number of hours, absurdly trivial activities seemed to occupy all the people in the asteroid. Burke and Keller sat in the thirty by thirty-foot instrument-room, each wearing a small metal half-cap with a black cube held atop it between a pair of clamps. Their expressions were absorbed and intent, while they seemed attired for a children’s halloween party. Now and again one of them exchanged one cube for another. About them there was a multiplicity of television screens, each screen presenting a picture of infinitely perfect quality. Every square foot of the outside of the asteroid could be seen on one or another of the screens. Then, besides, there were banks of screens which showed every square degree of the sky, with every star of every magnitude represented so that one could use a magnifying glass upon the screen to discover finer detail.

Once, during the hours when Burke and Keller were sitting quite still, Keller reached over and threw a switch. Nothing happened. Everything went on exactly as it had done before. He shook his head. And much later he went to one of the star-image screens. He moved an inconspicuous knob in a special fashion, and the star-image expanded and expanded until what had been a second of arc or less filled all the screen’s surface. The effect of an incredibly powerful telescope was obtained by the movement of one control. Keller restored the knob to its original place and the image returned to its former scale. These were the only actions which took place in the instrument-room.

In the lower part of the asteroid, not much more occurred. The entrance to the power and storage areas was not hidden. It simply had not been entered. Sandy and Holmes and Pam went gingerly down a corridor with doors on either side, and then down a ramp, and then into huge caverns filled with monstrous metal things. There was no sign of any motion anywhere, but gigantic power-leads led from the machines to massive switchboards, whose switches were thrown by relays operated from somewhere else.

Then there were other caverns which must have contained many varieties of stores. There were great cases, broken open and emptied. There were bins with only dust at their bottoms. There were shelves containing things which might have been textiles, but which crumbled at a touch. Some thousands of years in an absolute vacuum would have evaporated any substance giving any degree of flexibility. These objects were useless. There was a great room with a singular hundred-foot-high machine in it, but there was no vibration or sound to indicate that it was in operation. This, Sandy said decisively, was the artificial-gravity generator. She did not know how it worked. It would have been indiscreet to experiment.

She led the way through relatively small corridors to areas in which there were very many small compartments. These had been for foodstuffs. But they were empty. They had been emptied when the asteroid was abandoned.

Then they came to the crudely fashioned case with the cryptic symbols on its front.

“This is the thing Joe mentioned,” said Sandy. “They had writing. They’d have to, to be civilized. But this is the only writing we’ve seen. Why’d they write it?”

“To tell somebody something they’d miss, otherwise,” Pam said.

“Who’d come down here? Why not put it at the ship-lock where people could be expected to come?”

Holmes grunted. “Asking questions like that gets nowhere. It’s like asking how the garrison was supplied. There’s no answer. Or how it left.”

Sandy said in a surprised voice, as if saying something she hadn’t realized she knew. “There were service ships. They serviced the television eyes on the outside, and they drilled at launching missiles, and so on. They were modified fighting ships, made over after ships didn’t fight any more.”

She hesitated, then went on.

“It’s odd that I didn’t think of telling Joe this! Some of the food supply came from Earth at the time my cube was made. As a quartermaster officer, I was authorized to allow hunting on Earth in case of need. So the service-ships went to Earth and came back with mammoths tied to the outside of their hulls. They had to be re-hydrated, though. Frozen though they were, they dried out in the long trip through vacuum from Earth.”

Then she shivered a little.

Pam looked at her strangely. Holmes raised his eyebrows. He’d had one experience of training-cubes. Sandy’d had quite another. Holmes felt that instinctive slight resentment a man feels when he lacks a position of authority in the presence of a woman.

“In my time—in the cube’s time—there was even a hunting camp on Earth. Otherwise there simply wouldn’t be enough to eat! Women were clamoring to be sent to Earth to help with the food supply. To be sent to hunt for food was a reward for exemplary service.”

“Which is interesting,” observed Holmes, “but irrelevant. How was the asteroid normally supplied? How did the garrison leave? Where did it come from? Where did it go? Maybe the answer’s in this box. If it is,” he added, “it’ll be in the same language as the inscription, and we can’t read it.”

Archaeologists on Earth would have been enraptured by any part of the fortress, but anything which promised to explain as much as Holmes had guessed the case could, would be a treasure past any price.

But the five people in the asteroid had much more immediate and much more urgent problems to think of. They went on a little farther and came to a storeroom which had been filled with something, but now held only the remains of packing-cases. They looked ready to crumble if touched.

“There used to be weapons stored here,” Sandy said. “Hand-weapons. Not for the defense of the fortress, but for the—discipline police. For the men who kept the others obedient to orders.”

“I’d be glad to have one operating pea-shooter,” said Holmes.

Pam wrinkled her nose suddenly. She’d noticed something.

“I think—” she began, “I think—”

Holmes kicked at a shape which once was probably a case of wood or something similar. It collapsed into impalpable dust. It had dried out to absolute desiccation. It was stripped of every molecule which could be extracted by a total vacuum in thousands of years. It was brittle past imagining.

The collapse did not end with the object kicked. It spread. One case bulged as the support of another failed. The bulged case disintegrated. Its particles pressed on another. The dissolution spread fanwise until nothing remained but a carpeting of infinitely fine brown stuff. In one place, however, solid objects remained under the covering.

Holmes waded through the powder to the solid things. He brought them up. A case of hand-weapons had collapsed, but the weapons themselves kept their shape. They had transparent plastic barrels with curiously formed metal parts inside them.

“These might be looked into,” said Holmes.

He stuffed his pockets. The hand-weapons had barrels and handgrips and triggers. They were made to shoot, somehow.

“I think—” began Pam again.

“Don’t,” growled Holmes. “Maybe Sandy remembers when this place was different, but I’ve had enough of it as it is. Let’s go back to the ship and some fresh air.”

“But that’s what—”

Holmes turned away. Like the rest, he’d accepted great age, mentally, as a part of the nature of the fortress. But the collapse of emptied shipping-cases because they were touched was a shock. Where such decay existed, one could not hope to find anything useful for a modern emergency. He vanished.

Pam was indignant. She turned to Sandy.

“I wanted to say that I smelled fresh air,” she protested. “And he acts like that!”

Sandy was not listening. She frowned.

“He could lose his way down here,” she said shortly. “We’d better keep him in sight. I remember the way from my dream.”

They followed Holmes, who did make his way back to the upper levels and ultimately to the ship without guidance. But Pam was intensely indignant.

“We could have gotten lost down there!” she said angrily when they were back in familiar territory. “And he wouldn’t have cared! And I did smell fresh air! Not very fresh, but fresher than the aged and dried-out stuff we’re breathing now!”

“You couldn’t,” said Sandy practically. “There simply couldn’t be any, except in the ship where the hydroponic wall-gardens keep it fresh.”

“But I did!” insisted Pam.

Sandy shrugged. They went into the ship, which Holmes had already reached and where he sat gloomily beside a black cube. He would have to sleep to get anything from it. There were only two of the freakish-seeming metal caps which made the cubes intelligible to a man awake, and Burke and Keller were using them. Holmes felt offended.

Sandy looked at a clock and began to prepare a meal. Pam, brooding, helped her.

Burke and Keller came back to the ship together. Keller looked pale. Burke seemed utterly grim.

“There’s some stuff to be coded and sent back to Earth,” he told Sandy. “Keller’s got it written out. We know how to work the instruments up above, now. My brain’s reeling a little, but I think I’ll stay sane. Keller takes it in stride. And we know the trick the Enemy has.”

Sandy put out plates for five.

“What is it?”

“Gravity,” said Burke, evenly. “Artificial gravity. We don’t know how to make it, but the people who built this fortress did, and the Enemy does. So they’ve made artificial-gravity fields to give their ships the seeming mass of suns, and they’ve set them in close omits around each other. They’ll come spinning into this solar system. What will happen when objects with the mass of suns—artificial or otherwise—come riding through between our sun and its planets? There’ll be tidal stresses to crack the planets and let out their internal fires. There’ll be no stability left in the sun. Maybe it’ll be a low-grade nova when they’ve gone, surrounded by trash that once was worlds. Anyhow there’ll be no humans left! And then the Enemy will go driving on toward the other solar systems that the builders of this fortress own. They can’t conquer anything with a weapon like that, but they can surely destroy!”

Keller nodded distressedly. He gave Pam a number of sheets of paper, filled with his neat handwriting.

He said sorrowfully, “For Earth. In code.”

Sandy served the meal she had prepared.

“It’s a matter of days,” said Burke curtly. “Not weeks. Just days.”

He picked up a fork and began his meal.

“So,” he said after a moment, with a sort of unnatural calm, “we’ve got to get the thing licked fast. Up in the instrument-room there are some theory-cubes—lectures on theories with which the operators of the room were probably required to be familiar. They were intended to figure out what the Enemy might come up with, so it could at least he reported before the fortress was destroyed. The trick of sun-gravity fields was suggested as possible, but it seemed preposterously difficult. Apparently, it was. It took the Enemy some thousands of years to get it. But they’ve got it, all right!”

“How do you know?” demanded Holmes.

“The disk with the red sparks in it,” said Burke, “is a detector of gravity-fields. It sees by gravity, which is not radiation. Keller’s sending instructions back to Earth telling how to make such detectors.”

He busied himself with his food once more. After a moment he spoke again.

“We’re going to try to get some help,” he observed. “At least we’ll try to find out if there’s any help to be had. I think there’s a chance. There was a civilization which built this fortress. Something happened to it. Perhaps it simply collapsed, like Rome and Greece and Egypt and Babylonia back on Earth. But on Earth when an old civilization died a new, young one rose in its place. If the one that built this fort collapsed, maybe a new one has risen in its stead. If so, it will need to defend itself against the Enemy just like the old culture did. It might prefer to do its fighting here, instead of in its own land. I think we may be able to contact it.”
