Breakfast over, they marched out the gate into another compound, and fascinated interest displaced all of Jason"s concerns. In the center of the yard was a large capstan into which the first group of slaves were already fitting the end of their bar. Jason"s group, and the two others, shuffled into position and placed their bars, making a four-spoked wheel out of the capstan. An overseer shouted and the slaves groaned and threw their weight against the bars until they shuddered and began to turn; then trudging slowly, they kept the wheel moving.
Once this slogging labor was under way, Jason turned his attention to the crude mechanism they were powering. A vertical shaft from the capstan turned a creaking wooden wheel that set a series of leather belts in motion. Some of them vanished through openings into a large stone building, while the strongest strap of all turned the rocker arm of what could only be a counterbalanced pump. This all seemed like a highly inefficient way to go about pumping water, since there must be natural springs and lakes somewhere around. The pungent smell that filled the yard was hauntingly familiar, and Jason had just reached the conclusion that water couldn"t be the object of their labors when a throaty gurgling came from the standpipe of the pump and a thick black stream bubbled out.
"Petroleum-of course!" Jason said out loud. Then when the overseer gave him an ugly look and cracked his whip menacingly, he bent his attention to pushing.
This was the secret of the d"zertanoj, and the source of their power. Hills towered above the surrounding walls and mountains were visible nearby. But the captured slaves had been drugged so they would not even know in which direction they had been brought to this hidden site, or how long the trip was.
Here in this guarded valley they labored to pump the crude oil that their masters used to power their big desert wagons. Or did they use crude oil for this? The petroleum was gurgling out in a heavy stream now, and was running down an open trough that disappeared through the wall into the same building as the turning belts. What barbaric devilishness went on in there? A thick chimney crowned the building and produced clouds of black smoke, while from the various openings in the wall came a tremendous stench that threatened to lift the top off his head.
At the same moment that he realized what was going on in the building, a guarded door was opened and Edipon came out, blowing his sizable nose in a sc.r.a.p of rag. The creaking wheel turned, and when its rotation brought Jason around again he called out to him.
"Hey, Edipon, come over here. I want to talk to you. I"m the former Ch"aka, in case you don"t recognize me out of uniform."
Edipon gave him one look, then turned away, dabbing at his nose. It was obvious that slaves held no interest for him, no matter what their position had been before their fall. The slave driver ran over with a roar, raising his whip, while the slow rotation of the wheel carried Jason away. He shouted back over his shoulder.
"Listen to me-I know a lot, and can help you." Only a turned back was an answer, and the whip was already whistling down.
It was time for the hard sell. "You had better hear me-because I know that what comes out first is best. Yeow!" This last was involuntary as the whip landed.
Jason"s words were without meaning to the slaves as well as to the overseer, who was raising his whip for another blow, but their impact on Edipon was as dramatic as if he had stepped on a hot coal. He shuddered to a halt and wheeled about, and even at this distance Jason could see that a sickly grey tone had replaced the normal brown color of his skin.
"Stop the wheel!" Edipon shouted.
This unexpected command drew the startled attention of everyone. The gape-mouthed overseer lowered his whip while the slaves stumbled and halted and the wheel groaned to a stop. In the sudden silence Edipon"s steps echoed loudly as he ran to Jason, halting a hand"s breadth away, his lips drawn back from his teeth with tension as if he were prepared to bite.
"What was that you said?" He hurled the words at Jason while his fingers half plucked a knife from his belt.
Jason smiled, looking and acting calmer than he felt. His barb had gone home, but unless he proceeded carefully so would Edipon"s knife -into Jason"s stomach. This was obviously a very sensitive topic.
"You heard what I said-and I don"t think you want me to repeat it in front of all these strangers. I know what happens here because I come from a place far away where we do this kind of thing all the time. I can help you. I can show you how to get more of the best, and how to make your caroj work better. Just try me.
Only unchain me from this bar first and let"s get to some place private where we can have a nice chat."
Edipon"s thoughts were obvious. He chewed his lip and looked hotly at Jason, fingering the edge of his knife. Jason returned a smile of pure innocence and tapped his fingers happily on the bar, just marking time while he waited to be released. But in spite of the cold there was a rivulet of sweat trickling down his spine. He was gambling everything on Edipon"s intelligence, believing that the man"s curiosity would overcome the immediate desire to silence the slave who knew so much about things so secret, hoping that he would remember that slaves could always be killed, and that it wouldn"t hurt to ask a few questions first.
Curiosity won, and the knife dropped back into the sheath while Jason let his breath out in a relieved sigh. It had been entirely too close, even for a professional gambler; his own life on the board was a little higher stakes than he enjoyed playing for.
"Release him from the bar and bring him to me," Edipon ordered, then strode away in agitation. The other slaves watched wide-eyed as the blacksmith was rushed out, and with much confusion and shouted orders Jason"s chain was cut from the bar where it joined the heavy staple.
"What are you doing?" Mikah asked, and one of the guards backhanded him to the ground. Jason merely smiled and touched his finger to his lips as his chain was released and they led him away. He was free from bondage, and he would stay that way if he could convince Edipon that he would be of better use in some capacity other than dumb labor.
The room they led him to contained the first touches of decoration or self- indulgence that he had seen on this planet. The furniture was carefully constructed, with an occasional bit of carving to brighten it, and there was a woven cover on the bed. Edipon stood by a table, tapping his fingers nervously on the dark polished surface.
"Lock him up," he ordered the guards, and Jason was secured to a st.u.r.dy ringbolt that projected from the wall. As soon as the guards were gone Edipon stood in front of Jason and drew his knife. "Tell me what you know, or I will kill you at once."
"My past is an open book to you, Edipon. I come from a land where we know all the secrets of nature."
"What is the name of this land? Are you a spy from Appsala?"
"I couldn"t very well be, since I have never heard of the place." Jason pulled at his lower lip, wondering just how intelligent Edipon was, and just how frank he could be with him. This was no time to get tangled up in lies about the planetary geography: it might be best to try him on a small dose of the truth.
"If I told you I came from another planet, another world in the sky up among the stars, would you believe me?"
"Perhaps. There are many old legends that our forefathers came from a world beyond the sky, but I have always dismissed them as religious drivel, fit only for women."
"In this case the girls happen to be right. Your planet was settled by men whose ships crossed the emptiness of s.p.a.ce as your caroj pa.s.s over the desert.
Your people have forgotten about that, and have lost the science and knowledge you once had, but on other worlds the knowledge is still held."
"Madness!"
"Not at all. It is science, though many times confused as being the same thing. I"ll prove my point. You know that I could never have been inside of your mysterious building out there, and I imagine you can be sure no one has told me its secrets. Yet I"ll bet that I can describe fairly accurately what is in there-not from seeing the machinery, but from knowing what must be done to oil in order to get the products you need. You want to hear?"
"Proceed," Edipon said, sitting on a corner of the table and balancing the knife loosely in his palm.
"I don"t know what you call it, the device, but in the trade it is a pot still used for fractional distillation. Your crude oil runs into a tank of some kind, and you pipe it from there to a retort, some big vessel that you can seal airtight. Once it is closed, you light a fire under the thing and try to get all the oil to an even temperature. A gas rises from the oil and you take it off through a pipe and run it through a condenser, probably more pipe with water running over it. Then you put a bucket under the open end of the pipe and out of it drips the juice that you burn in your caroj to make them move."
Edipon"s eyes opened wider and wider while Jason talked, until they seemed almost bulging from his head. "Demon!" he screeched, and tottered towards Jason with the knife extended. "You couldn"t have seen, not through stone walls. Only my family have seen, no others- I"ll swear to that!"
"Keep cool, Edipon. I told you that we have been doing this stuff for years in my country." He balanced on one foot, ready for a kick at the knife in case the old man"s nerves did not settle down. "I"m not out to steal your secrets. In fact, they are pretty small potatoes where I come from, where every farmer has a still for cooking up his own mash and saving on taxes. I"ll bet I can even put in some improvements for you, sight unseen. How do you monitor the temperature on your cooking brew? Do you have thermometers?"
"What are thermometers?" Edipon asked, forgetting the knife for the moment, drawn on by the joy of a technical discussion.
"That"s what I thought. I can see where your bootleg joy-juice is going to take a big jump in quality, if you have anyone here who can do some simple gla.s.s- blowing. Though it might be easier to rig up a coiled hi-metallic strip. You"re trying to boil off your various fractions, and unless you keep an even and controlled temperature you are going to have a mixed brew. The thing you want for your engines are the most volatile fractions, the liquids that boil off first, like gasoline and benzene. After that you raise the temperature and collect kerosene for your lamps, and so forth right on down the line until you have a nice ma.s.s of tar left to pave your roads with. How does that sound to you?"
Edipon had forced himself into calmness, though a jumping muscle in his cheek betrayed his inner tension. "What you have described is the truth, though you were wrong on some small things. But I am not interested in your thermometer nor in improving our water-of-power. It has been good enough for my family for generations and it is good enough for me."
"I suppose you think that line is original?"
"But there is something that you might be able to do that would bring you rich rewards," Edipon went on. "We can be generous when needs be. You have seen our caroj and ridden on one, and seen me go into the shrine to intercede with the sacred powers to make us move. Can you tell me what power moves the caroj?"
"I hope this is the final exam, Edipon, because you are stretching my powers of extrapolation. Stripping away the "shrines" and "sacred powers," I would say that you go into the engine room to do a piece of work with very little praying involved. There could be a number of ways of moving those vehicles, but let"s think of the simplest. This is top of the head now, so no penalties if I miss any of the fine points. Internal combustion is out. I doubt if you have the technology to handle it, plus the fact there was a lot of do about the water tank and it took you almost an hour to get under way. That sounds as if you were getting up a head of steam- The safety valve! I forgot about that.
"So it is steam. You go in, lock the door, of course, then open a couple of valves until the fuel drips into the firebox, then you light it. Maybe you have a pressure gauge, or maybe you just wait until the safety valve pops to tell you if you have a head of steam. Which can be dangerous, since a sticking valve could blow the whole works right over the mountain. Once you have the steam, you crack a valve to let it into the cylinders and get the thing moving. After that you just enjoy the trip, of course making sure that the water is feeding to your boiler all right, that your pressure stays up, your fire is hot enough, all your bearings are lubricated, and the rest. . ."
Jason looked on astounded as Edipon did a little jig around the room, holding his robe up above his bony knees. Bouncing with excitement, he jabbed his knife into the table top and rushed over to Jason and grabbed him by the shoulders, shaking him so that his chain rattled.
"Do you know what you have done?" he asked excitedly. "Do you know what you have said?"
"I know well enough. Does this mean that I have pa.s.sed the exam and that you will listen tome now? Was I right?"
"I don"t know if you are right or not; I have never seen the inside of one of the Appsalan devil-boxes." He danced around the room again. "You know more about their-what do you call it?-engine, than I do. I have only spent my life tending them and cursing the people of Appsala who keep the secret from us. But you will reveal it to us! We will build our own engines, and if they want water-of- power they will have to pay dearly for it."
"Would you mind being a little bit clearer," Jason asked. "I have never heard anything so confused in all my life."
"I will show you, man from a far world, and you will reveal the Appsalan secrets to us. I see the dawn of a new day for Putl"ko arriving."
He opened the door and shouted for the guards, and for his son, Narsisi.
The latter arrived as they were unlocking Jason, who recognized him as the same droopy-eyed, sleepy-looking d"zertano who had been helping Edipon to drive their ungainly vehicle.
"Seize this chain, my son, and keep your club ready to kill this slave if he makes any attempt to escape. Otherwise, do not harm him, for he is very valuable. Come."
Narsisi tugged on the chain, but Jason only dug his heels in and did not move. They looked at him, astonished.
"Just a few things before we go. The man who is to bring the new day to Putl"ko is not a slave. Let us get that straight before this operation goes any further. We"ll work out something with chains or guards so I can"t escape, but the slavery thing is out."
"But-you are not one of us, therefore you must be a slave."
"I"ve just added a third category to your social order: employee. Though reluctant, I am still an employee, skilled labor, and I intend to be treated that way. Figure it out for yourself. Kill a slave, and what do you lose? Very little, if there is another slave in the pens that can push in the same place. But kill me, and what do you get? Brains on your club-and they do you no good at all there."
"Does he mean I can"t kill him?" Narsisi asked his father, looking puzzled as well as sleepy.
"No, he doesn"t mean that," Edipon said. "He means if we kill him there is no one else who can do the work he is to do for us. But I do not like it. There are only slaves and slavers; anything else is against the natural order. But he has us trapped between satano and the sandstorm, so we must allow him some freedom.
Bring the slave now-I mean the employee-and we will see if he can do the things he has promised. If he does not, I will have the pleasure of killing him, because I do not like his revolutionary ideas."
They marched single file to a locked and guarded building with immense doors, which were pulled open to reveal the ma.s.sive forms of seven caroj.
"Look at them!" Eclipon exclaimed, and pulled at his nose. "The finest and most beautiful of constructions, striking fear into our enemies" hearts, carrying us fleetly across the sands, bearing on their backs immense loads, and only three of the d.a.m.ned things are able to move."
"Engine trouble?" Jason asked lightly.
Edipon cursed and fumed under his breath, and led the way to an inner courtyard where stood four immense black boxes painted with death heads, splintered bones, fountains of blood, and cabalistic symbols, all of a sinister appearance.
"Those swine in Appsala take our water-of-power and give nothing in return. Oh yes, they let us use their engines, but after running for a few months the cursed things stop and will not go again, then we must bring them back to the city to exchange for a new one, and pay again and again."
"A nice racket," Jason said, looking at the sealed covering on the engines.
"Why don"t you just crack into them and fix them yourself? They can"t be very complex."
"That is death!" Edipon gasped, and both cl"zertanoj recoiled from the boxes at the thought. "We have tried that, in my father"s father"s day, for we are not superst.i.tious like the slaves, and we know that these are man-made not G.o.d- made. However, the tricky serpents of Appsala hide their secrets with immense cunning. If any attempt is made to break the covering, horrible death leaks out and fills the air. Men who breathe the air die, and even those who are only touched by it develop immense blisters and die in pain. The men of Appsala laughed when this happened to our people, and after that they raised the price even higher."
Jason circled one of the boxes, examining it with interest, trailing Narsisi behind him at the end of the chain. The thing was higher than his head and almost twice as long. A heavy shaft emerged through openings on opposite sides, probably the power takeoff for the wheels. Through an opening in the side he could see inset handles and two small colored disks, and above these were three funnel-shaped openings painted like mouths. By standing on tiptoe, Jason could look on top, but there was only a f.l.a.n.g.ed, sooty opening there that must be for attaching a smokestack. There was only one more opening, a smallish one in the rear, and no other controls on the garish container.
"I"m beginning to get the picture, but you will have to tell me how you work the controls."
"Death before that!" Narsisi shouted. "Only my family-"
"Will you shut up!" Jason shouted back. "Remember? You"re not allowed to browbeat the help any more. There are no secrets here. Not only that, but I probably know more about this thing than you do, just by looking at it. Oil, water, arid fuel go in these three openings, you poke a light in somewhere, probably in that smoky hole under the controls, and open one of those valves for fuel supply; another one is to make the engine go slower and faster, and the third is for your water feed. The disks are indicators of some kind." Narsisi paled and stepped back "So now keep still while I talk to your dad."
"It is as you say," Edipon said. "The mouths must always be filled, and woe betide if they go empty; for the powers will halt, or worse. Fire goes in here, as you guessed, and when the green finger comes forward this lever may be turned for motion. The next is for great speed, or for going slow. The very last is under the sign of the red finger, which when it points indicates need, and the handle must be turned and held turned until the finger retires. White breath comes from the opening in back. That is all there is."
"About what I expected," Jason muttered, and examined the container wall, rapping it with his knuckles until it boomed. "They give you the minimum of controls to run the thing, so you won"t learn anything about the basic principles involved. Without the theory, you would never know what the handles control, or that the green indicator comes out when you have operating pressure, and the red one when the water level is low in the boiler. Very neat. And the whole thing sealed up in a can and b.o.o.by-trapped in case you have any ideas of going into business for yourself. The cover sounds as if it is doublewalled, and from your description I would say that it has one of the vesicant war gases, like mustard gas, sealed inside there in liquid form. Anyone who tries to cut their way in will quickly forget their ambitions after a dose of that. Yet there must be a way to get inside the case and service the engine; they aren"t just going to throw them away after a few months" use. And considering the level of technology displayed by this monstrosity, I should be able to find the tricks and get around any other built-in traps. I think I"ll take the job."
"Very well, begin."
"Wait a minute, boss. You still have a few things to learn about hired labor.
There are always certain working conditions and agreements involved, all of which I"ll be happy to list for you."
8.
"That I do not understand is why you must have the other slave?" Narsisi whined. "To have the woman of course is natural, as well as to have quarters of your own. My father has given his permission. But he also said that I and my brothers are to help you, that the secrets of the engine are to be revealed to no one else."
"Then trot right over to him and get permission for the slave Mikah to join me in the work. You can explain that he comes from the same land that I do, and that your secrets are mere children"s toys to him. And if your dad wants any other reasons, tell him that I need skilled aid, someone who knows how to handle tools and who can be trusted to follow directions exactly as given. You and your brothers have entirely too many ideas of your own about how things should be done, and a tendency to leave details up to the G.o.ds, and have a good bash with the hammer if things don"t work the way they should."
Narsisi retired, seething and muttering to himself, while Jason huddled over the oil stove planning the next step. It had taken most of the day to lay down logs for rollers and to push the sealed engine out into the sandy valley, far from the well site; open s.p.a.ce was needed for any experiments in which a mistake could release a cloud of war gas. Even Edipon had finally seen the sense of this, though all of his tendencies were to conduct the experiments with great secretiveness, behind locked doors. He had granted permission only after skin walls had been erected to form an enclosure that could be guarded; it was only incidental that they acted as a much appreciated windbreak.
After a good deal of argument the dangling chains and shackles had been removed from Jason"s arms and lightweight leg-irons subst.i.tuted. He had to shuffle when he walked, but his arms were completely free; this was a great improvement over the chains, even though one of the brothers kept watch with a c.o.c.ked crossbow as long as Jason wasn"t fastened down. Now he had to get some tools and some idea of the technical knowledge of these people before he could proceed, which would necessarily entail one more battle over their precious secrets.
"Come on," he called to his guard, "let"s find Edipon and give his ulcers another twinge."
After his first enthusiasm, the leader of the d"zertanoj was getting little pleasure out of his new project.
"You have quarters of your own," he grumbled to Jason, "and the slave woman to cook for you, and I have just given permission for the other slave to help you. Now more requests-do you want to drain all the blood from my body?"
"Let"s not dramatize too much. I simply want some tools to get on with my work, and a look at your machine shop or wherever it is you do your mechanical work. I have to have some idea of the way you peepie solve mechanical problems before I can go to work on that box of tricks out there in the desert."
"Entrance is forbidden."
"Regulations are snapping like straws today, so we might as well go on and finish off a few more. Will you lead the way?"
The guards were reluctant to open the refinery building gates to Jason, and there were worried looks and much rattling of keys. A brace of elderly d"zertanoj, stinking of oil fumes, emerged from the interior and joined in a shouted argument with Edipon, whose will finally prevailed. Chained again, and guarded like a criminal, Jason was begrudgingly led into the dark interior, the contents of which were depressingly anticlimactic.
"Really primitive," Jason sneered, and he kicked at the boxful of clumsy hand-forged tools. The work was of the crudest, the product of a sort of neolithic machine age. The distilling retort had been laboriously formed from sheet copper and clumsily riveted together. It leaked mightily, as did the soldered seams on the hand-formed pipe. Most of the tools were blacksmith"s tongs and hammers for heating and beating out shapes on the anvil. The only things that gladdened Jason"s heart were the ma.s.sive drill press and lathe that worked off the slave- power drive belts. In the tool holder of the lathe was clamped a chip of some hard mineral that did a good enough job of cutting the forged iron and low-carbon steel. Even more cheering was the screw-thread advance on the cutting head, which was used to produce the ma.s.sive nuts and bolts that secured the caro wheels to their shafts.
It might have been worse. Jason sorted out the smallest and handiest tools and put them aside for his own use in the morning. The light was almost gone now and there would be no more work this day.
They left in armed procession, as they had come, and two guards showed him to the kennel-like room that was to be his private quarters. The heavy bolt thudded shut in the door behind him and he winced at the thick fumes of kerosene through which the light of the singlewick lamp barely penetrated.
Ijale crouched over the small oil stove cooking something in a pottery vessel. She looked up and smiled hesitatingly at Jason, then turned quickly back to the stove. Jason walked over, sniffed, and shuddered.
"What a feast! Kreno soup, and I suppose followed by fresh kreno and kreno salad. Tomorrow I"ll see about getting a little variety into the diet."
"Ch"aka is great," she whispered without looking up. "Ch"aka is powerful . .
"Jason is the name, I lost the Ch"aka job when they took the uniform away."
". . . Jason is powerful to work charms on the d"zertanoj and make them do what he will. His slave thanks you."
