Chapter 8

“I don’t believe it,” said Holmes flatly.

Burke shrugged. He found that he was tense all over, so he took some pains to appear wholly calm.

“It isn’t reasonable!” insisted Holmes. “It doesn’t make sense!”

“The question,” observed Burke, “isn’t whether it makes sense, but whether it’s fact. According to the last word from Earth, they’re still insisting that the ship’s drive is against all reason. But we’re here. And speaking of reason, would the average person look at this place and say blandly, ‘Ah, yes! A fortress in space. To be sure!’ Would they? Is this place reasonable?”

Holmes grinned.

“I’ll go along with you there,” he agreed. “It isn’t. But you say its garrison was men. Look here! Have you seen a place before where men lived without writings in its public places? They tell me the ancient Egyptians wrote their names on the Sphinx and the Pyramids. Nowadays they’re scrawled in phone booths and on benches. It’s the instinct of men to autograph their surroundings. But there’s not a line of written matter in this place! That’s not like men!”

“Again,” said Burke, “the question isn’t of normality, but of fact.”

“Then I’ll try it,” said Holmes skeptically. “How does it work?”

“I don’t know. But put a cube about a yard from your head, and doze off. I think you’ll have an odd dream. I did. I think the information you’ll get in your dream will check with what you find around you. Some of it you won’t have known before, but you’ll find it’s true.”

“This,” said Holmes, “I will have to see. Which cube do I try it with, or do I use all of them?”

“There’s apparently no way to tell what any of them contains,” said Burke. “I went back to the storeroom and brought a dozen of them. Take any one and put the others some distance away--maybe outside the ship. I’m going to talk to Keller. He’ll make a lot of use of this discovery.”

Holmes picked up a cube.

“I’ll try it,” he said cheerfully. “I go to sleep, perchance to dream. Right! See you later.”

Burke moved toward the ship’s air-lock.

“Pam and I have some housekeeping to do,” Sandy said.

Burke nodded abstractedly. He left the ship and headed along the mile-long corridor with the turn at the end, a second level and another turn, and then the flight of steps to the instrument-room. As he walked, the sound of his footsteps echoed and reëchoed.

Behind him, Holmes set a cube in a suitable position and curled up on one of the side-wall bunks in the upper compartment of the spaceship.

“We’ll go downstairs,” said Sandy.

Pam parted her lips to speak, and did not. They disappeared down the stair to the lower room. Then Sandy came back and picked up the extra cubes.

“Joe said to move them,” she explained.

She disappeared again. Holmes settled himself comfortably. He was one of those fortunate people who are able to relax at will. Actually, in his work he normally did his thinking while on his feet, moving about his yacht-building plant or else sailing one of his own boats. He simply was not a sit-down thinker. Sitting, he could doze at almost any time he pleased, and for a yachtsman it was a useful ability. He could go for days on snatched catnaps when necessary. Conversely he could catnap practically at will.

He yawned once or twice and settled down confidently. In five minutes or less...

_He wriggled down into an opening barely large enough to admit his body. The top clamped and sealed overhead. He fitted his feet into their proper stirrup-like holders and fixed his hands on the controls. There was violent acceleration and he shot away and ahead. Behind him the jagged shape of the fortress loomed. He swung his tiny ship. He drove fiercely for the tiny rings of red glow which centered themselves in the sighting-screen before him. He drove and drove, while the fortress dwindled to a dot and then vanished._

_On either side of his ship a ten-foot steel globe clung. He checked them over, tense with the realization that he must very soon be within the practical timing-range of the new Enemy solid missiles. He made minute adjustments in the settings of the globes._

_He released them together. They went swinging madly away at the end of a hair-thin wire which would sustain the tons of stress that centrifugal force gave the spheres. They spiraled toward darkness with its background of innumerable stars. The Enemy would be puzzled, this time! They’d developed missile-weapons with computing sights. In their last attack, five hundred years before, the Enemy had been defeated by the self-driving globes that had an utterly incredible acceleration. It was reported from the Cathor sector that in this current attack they had missile-weapons with a muzzle-velocity of hundreds of miles per second, which could actually anticipate a globe with a hundred-sixty-gravity drive. They could fire a solid shot to meet it and knock it down, because of some incredible computer-system which was able to calculate a globe’s trajectory and meet it in space. They were smart, the Enemy!_

_The two globes went spinning toward the Enemy. Linked together, they spun round and round and no conceivable computer could calculate the path of either one so a projectile could hit. They did not travel in a straight line, as a trajectory in space should be. Whirling as they did around a common center of gravity, with the plane of their circling at a sharp angle to their line of flight, it was not possible to range them for gunfire. Their progress was in a series of curves, each at a different distance, which no mere calculator could solve without direction. A radar could not pick up the data a computer would need. One or the other globe might be hit, but it was far from likely._

_The pilot of the one-man ship saw the blue-white flame of a hit. He flung his ship about and sped back toward the fortress. The Enemy would beat this trick, in time. Four thousand years before they’d almost won, when they invaded the Old Nation. They were getting bolder now. There was a time when a sound beating sent them back beyond the Coal-sack to lick their wounds for two thousand years or better. Lately they came more often. There’d been a raid in force only five hundred years back, and only fifteen before that... _

Holmes, obviously, had the odd dream Burke had prophesied. But Burke was up in the instrument-room by then. Keller gazed absorbedly at a vision-plate. It showed a section of the exterior surface of the asteroid--harsh, naked rock, with pitiless sunlight showing the grain and structure of the rock-crystals. Where there was shadow, the blackness was absolute. As Burke entered, Keller turned a knob. The image changed to a picture of a compartment inside the fortress. It was a part of the maze of rooms and galleries that none of the newcomers had visited. Panels and bus-bars and things which were plainly switches covered its walls. It was a power-distribution center. Keller turned the knob back, and the view of the outside of the asteroid returned.

Keller turned and blinked at Burke, and then said happily, “Look!”

He went to another vision-screen with an image of another part of the outer surface. He turned that knob, and the image dissolved into another. This was a gigantic room, lighted like more familiar places. In its center there was an enormous, gigantic machine. There were domes of metal, with great rods of silvery stuff reaching across emptiness between them. There were stairs by which one could climb to this part and that. Judging by the steps and the size of the light-tubes, the machine was the size of a four-storey house. And on the floor there were smaller machines, all motionless and all cryptic.

Keller said with conviction, “Power!”

Burke stared. Keller recovered the original view and went to still other plates. In succession, as he turned the knobs, Burke saw compartment after compartment. There was one quite as huge as the one containing the power-generating machine. It contained hemispheres bolted ten feet above the floor on many columns. There was a network of bus-bars, it seemed, overlying everything, and there were smaller devices on the floor below it.

“Gravity!” said Keller with conviction.

“Good enough,” said Burke. “We’ve found something too, which may be useful with those machines. If we can--”

Keller held up his hand and went to one special screen. When he changed the image, the new one was totally unlike any of the others. This was a close-up. It showed a clumsy, strictly improvised and definitely cobbled metal case against a wall. It had been made by inept hands. It was remarkable to see such indifferent workmanship here. But the really remarkable thing was that the face of the box contained an inscription, burned into the metal as if by a torch. The symbols had no meaning to Burke, of course. But this was an inscription in a written language.

Keller rubbed his hands, beaming.

“It could be a message for somebody who’d come later,” said Burke. “It’s hard to think of it being anything else. But it wasn’t placed for us to find. It should have been set up beside the ship-lock we were expected to come in by and did come in by.”

“We’ll see,” said Keller zestfully. “Come on!”

Burke followed him. Keller seemed somehow to know the way. They went all the way back to the ship-lock, passed it, and then Keller dived off to the right, down an unsuspected ramp. There were galleries running in every direction here, crossing each other and opening upon an indefinite number of what must have been storerooms. Presently Keller pointed.

There was the case against the wall. It faced a wide corridor. It did not belong here. It was totally unlike any other artifact they had seen, because it seemed to have been made totally without skill. Yet there was an inscription--and the making of written records had appeared to be a skill the former occupants of the asteroid had not possessed. Keller very zestfully essayed to open it. He failed.

Burke said, “We’ll have to use tools to get it open.”

“Somebody made it,” said Keller, “just before the garrison went away. They made it here!”

“Quite likely,” agreed Burke. “We’ll get at it presently. Now listen, Keller! I came along because a message might be useful. I think Holmes has found out something, though what it may be I can’t guess. Come along with me. There’ve been developments and I want to hold a council of war. And I think I do mean war!”

He led the way back toward the ship. When they arrived, Holmes was awake and growling because of Burke’s absence.

“You win,” he told Burke. “I had a dream, and it wasn’t a dream. I know something about those metal globes. They’ve got drives in them, and they can accelerate to a hundred and sixty gees, and I don’t think I’ll ride one.”

Wryly, he told Burke what he’d experienced.

“I’m not too much surprised,” said Burke. “I’ve managed two cube-experiences myself. I figure that these cubes trained men to operate things, without training their brains in anything else. They’d make illiterates into skilled men in a particular line, so anybody could do the work a highly trained man would otherwise be needed for. In one of my two cube-dreams I was a gun-pointer on one of those machines up on the third level. In the second cube-dream I was a rocket-pilot.”

“No rockets in my cube,” protested Holmes.

“Different period,” said Burke. “Maybe, anyhow. In my dream we were using rockets to fight with, and the war was close. The enemy had taken some planets off Kandu--wherever that is!--and the situation was bad. We went out of here in rockets and fought all over the sky. But then there were supplies coming from home, and fresh fighting men turning up.” He stopped abruptly. “How’d they come? I don’t know. But I know they didn’t come in spaceships. They just came, and they were new men and we veterans patronized them. The devil! Holmes, you say the globes have a hundred-sixty-gee drive! Nobody’d use rockets if drives like that were known!”

“To stay in the party,” Sandy said suddenly, with something like defiance, “I tried a cube, too. And I was a sort of supply-officer. I had the experience of being responsible for supply and being short of everything and improvising this and that and the other to keep things up to fighting standard. It wasn’t easy. The men grumbled, and we lacked everything. There was no fighting in my time, and there hadn’t been for centuries. But we knew the Enemy hadn’t given up and we had to be ready, generation after generation, even when nothing happened. And we knew that any minute the Enemy might throw something unexpected, some new weapon, at us.”

“History-cubes,” said Keller interestedly. “Different periods. Right?”

“Dammit, yes!” said Burke. “We’ve got accounts of past times and finished battles, but we need to know who’s coming and what to do about it! Maybe the rocket-dream was earliest in time. But how could a race with nothing better than rockets ever get here? And how could they supply the building of a place like this?”

There was no answer. Facts ought to fit together. When they don’t, they are useless.

“We’ve got snatches of information,” said Burke. “But we don’t know who built this fort, or why, except that there was a war that lasted thousands of years, with pauses for centuries between battles.” He waved a hand irritably. “The Enemy tries to think up new weapons. They do. They try them. So far, they’ve been countered. But we’re not prepared to fight a new weapon. Maybe the fort is set to battle old ones, but we don’t know how to use it even for that! We’ve got to--”

“I think--” began Keller.

“I’d give plenty for a service manual on the probably useless weapons we do have,” said Burke angrily. “Incidentally, Keller just found what may be an explanation of how and why this place was abandoned.”

Keller said suddenly, “Where would service manuals be?”

He moved, almost running, toward the air-lock. Burke started to swear, and stopped.

“A service-and-repair manual,” he snapped, “would be near the equipment it described. How many little shelves with boxes on them have we seen? They’re just the right size to hold cubes! And where are they? Next to those fighting machines next to the door of the room where the ten-foot globes are! There’s a shelf of them in the instrument-room! Let’s find out how to fight with this misbegotten shell of a space-fort! There’ll be no help coming to us, but if the Enemy’s held off for thousands of years while this civilization fell apart, we might as well try to hold it together for a few minutes or seconds longer! Let’s go get some real instruction-cubes!”

Keller was already gone. The others followed. Once they saw Keller in the far, far distance, hastening toward the instrument-room. Behind him, after almost running down the long corridor, Burke swung into the room where hundreds of ten-foot metal globes waited for the fortress to be remanned and to go into action again. Inside the door he found the remembered shelf, with two small boxes fastened to it. He pulled down one box and opened it. There was a black cube inside it. He thrust it upon Holmes.

“Here!” he said feverishly. “Find out how those globes work! Find out what’s in them, how they drive!”

He ran. To the end of the corridor and up the ramp and past the supposed bunk-rooms and mess-halls. Up to the level where the ugly metal machines stood, each in its separate cubicle. There were little shelves inside each door. Each shelf contained a single box. Burke took one, two, and then stopped short.

“They’ll be practically alike,” he muttered. “No need.”

He put one back. And then he felt almost insanely angry. One would need at least to be able to doze, to make use of the detailed, vivid, and utterly convincing material contained in the black cubes. And how could any man doze or sleep for the purpose of learning such desperately needed data? He’d need almost not to want the information to be able to sleep to get it!

Sandy and Pam overtook him as he stood in harried frustration with a black cube in his hands.

“Listen to me, Joe,” said Sandy. “We’ve all taken chances, but if you get recurrent dreams from every cube you doze near--”

“When that happened to me,” snapped Burke, “I was eleven years old and had one moment only. And that dream wasn’t affected by the others in the cubes that came after it. And anyhow, no matter what happens to Holmes and me, we have to get these things ready for use! I don’t know what we’ll use them against. I don’t know whether they’ll be any use at all. But I’ve got to try to use them, so I’ve got to try to find out how!”

Sandy opened her mouth to speak again.

“I’m going off to fret myself to sleep,” added Burke. “Holmes will be trying it too. And Keller.”

“I don’t think it’s necessary,” said Sandy.

“Why?”

“You found a sort of library of cubes. How useful would they be if one had to doze off to read them? How handy would a manual about repairing a weapon be, if somebody had to take a nap to get instructions? It wouldn’t make sense!”

“Go on!” said Burke impatiently.

“Why not look in the library?” asked Sandy. “As a quartermaster officer, I think I knew that there was a reading-device for the cubes, like a projector for microfilm. It might have been taken away, but also--”

“Come along!” snapped Burke. “If that’s so, it’s everything! And it ought to be so!”

They hastened to the vast, low-ceilinged room which was filled with racks of black cubes. They were stacked in their places. At the far corner they found a desk and a cabinet. In the cabinet they found two objects like metal skull-caps, with clamps atop them. A cube would fit between the clamps. Burke feverishly sat a cube in position and put the skull-cap on his head. His expression was strange. After an instant he took it off and reversed the cube. He put it on. His face cleared. He lifted it off.

“I had it on backwards the first time,” he said curtly. “This is better than dreaming the stuff. This lets you examine things in detail. You know you’re receiving something. You don’t think you’re actually experiencing. We’ll get this other reading-machine to Keller, so he can understand the equipment in the instrument-room. Holmes will have to wait.”

Sandy said, “I can use him. Doesn’t it occur to you, Joe, that we’ve only partly explored the top half of the fortress? We’ve only looked at what’s between us and the instrument-room. There are all the stores--there were stores! And the generators down below. I can lead the way there now!”

“What do you know about the weapons?” demanded Burke.

“Nothing,” said Sandy. “But I know something about the morale of the garrison. When grumbling began, discipline tightened up. And that worked for the men, but the women--”

“Women!” said Pam incredulously.

“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.”
