Space Prison Part 22

PART 3

When spring came Steve Schroeder was leader, as Lake had wanted. It was a duty and a responsibility that would be under circ.u.mstances different from those of any of the leaders before him. The grim fight was over for a while. They were adapted and increasing in number; going into Big Summer and into a renascence that would last for fifty years. They would have half a century in which to develop their environment to its fullest extent. Then Big Fall would come, to destroy all they had accomplished, and the Gerns would come, to destroy them.

It was his job to make certain that by then they would be stronger than either.

He went north with nine men as soon as the weather permitted. It was hard to retrace the route of the summer before, without compa.s.ses, among the hills which looked all the same as far as their binoculars could reach, and it was summer when they saw the hill with the monument. They found Lake's bones a few miles south of it, scattered by the scavengers as were the little bones of his mocker. They buried them together, man and mocker, and went silently on toward the hill.

They had brought a little hand-cranked diamond drill with them to bore holes in the hard granite and black powder for blasting. They mined the vein, sorting out the ore from the waste and saving every particle.

The vein was narrow at the surface and pinched very rapidly. At a depth of six feet it was a knife-blade seam; at ten feet it was only a red discoloration in the bottom of their shaft.

"That seems to be all of it," he said to the others. "We'll send men up here next year to go deeper and farther along its course but I have an idea we've just mined all of the only iron vein on Ragnarok. It will be enough for our purpose."

They sewed the ore in strong rawhide sacks and then prospected, without success, until it was time for the last unicorn band to pa.s.s by on its way south. They trapped ten unicorns and hobbled their legs, with other ropes reaching from horn to hind leg on each side to prevent them from swinging back their heads or even lifting them high.

They had expected the capture and hobbling of the unicorns to be a difficult and dangerous job and it was. But when they were finished the unicorns were helpless. They could move awkwardly about to graze but they could not charge. They could only stand with lowered heads and fume and rumble.

The ore sacks were tied on one frosty morning and the men mounted. The horn-leg ropes were loosened so the unicorns could travel, and the unicorns went into a frenzy of bucking and rearing, squealing with rage as they tried to impale their riders.

The short spears, stabbing at the sensitive spot behind the jawbones of the unicorns, thwarted the backward flung heads and the unicorns were slowly forced into submission. The last one conceded temporary defeat and the long journey to the south started, the unicorns going in the run that they could maintain hour after hour.

Each day they pushed the unicorns until they were too weary to fight at night. Each morning, rested, the unicorns resumed the battle. It became an expected routine for both unicorns and men.

The unicorns were released when the ore was unloaded at the foot of the hill before the caves and Schroeder went to the new waterwheel, where the new generator was already in place. There George Craig told him of the unexpected obstacle that had appeared.

"We're stuck," George said. "The aluminum ore isn't what we thought it would be. It's scarce and very low grade, of such a complex nature that we can't refine it to the oxide with what we have to work with on Ragnarok."

"Have you produced any aluminum oxide at all?" Schroeder asked.

"A little. We might have enough for the wire in a hundred years if we kept at it hard enough."

"What else do you need--was there enough cryolite?" he asked.

"Not much of it, but enough. We have the generator set up, the smelting box built and the carbon lining and rods ready. We have everything we need to smelt aluminum ore--except the aluminum ore."

"Go ahead and finish up the details, such as installing the lining," he said. "We didn't get this far to be stopped now."

But the prospecting parties, making full use of the time left them before winter closed down, returned late that fall to report no sign of the ore they needed.

Spring came and he was determined they would be smelting aluminum before the summer was over even though he had no idea where the ore would be found. They needed aluminum ore of a grade high enough that they could extract the pure aluminum oxide. Specifically, they needed aluminum oxide....

Then he saw the answer to their problem, so obvious that all of them had overlooked it.

He pa.s.sed by four children playing a game in front of the caves that day; some kind of a checker-like game in which differently colored rocks represented the different children. One boy was using red stones; some of the rubies that had been brought back as curios from the chasm.

Rubies were of no use or value on Ragnarok; only pretty rocks for children to play with....

Only pretty rocks?--_rubies and sapphires were corundum, were pure aluminum oxide!_

He went to tell George and to arrange for a party of men to go into the chasm after all the rubies and sapphires they could find. The last obstacle had been surmounted.

The summer sun was hot the day the generator hummed into life. The carbon-lined smelting box was ready and the current flowed between the heavy carbon rods suspended in the cryolite and the lining, transforming the cryolite into a liquid. The crushed rubies and sapphires were fed into the box, glowing and glittering in blood-red and sky-blue scintillations of light, to be deprived by the current of their life and fire and be changed into something entirely different.

When the time came to draw off some of the metal they opened the orifice in the lower corner of the box. Molten aluminum flowed out into the ingot mold in a little stream; more beautiful to them than any gems could ever be, bright and gleaming in its promise that more than six generations of imprisonment would soon be ended.

The aluminum smelting continued until the supply of rubies and sapphires in the chasm had been exhausted but for small and scattered fragments.

It was enough, with some aluminum above the amount needed for the wire.

It was the year one hundred and fifty-two when they smelted the aluminum. In eight more years they would reach the middle of Big Summer; the suns would start their long drift southward, not to return for one hundred and fifty years. Time was pa.s.sing swiftly by for them and there was none of it to waste....

The making of ceramics was developed to an art, as was the making of different types of gla.s.s. Looms were built to spin thread and cloth from woods goat wool, and vegetable dyes were discovered. Exploration parties crossed the continent to the eastern and western seas: salty and lifeless seas that were bordered by immense deserts. No trees of any kind grew along their sh.o.r.es and ships could not be built to cross them.

Efforts were continued to develop an inorganic field of chemistry, with discouraging results, but in one hundred and fifty-nine the orange corn was successfully adapted to the elevation and climate of the caves.

There was enough that year to feed the mockers all winter, supply next year's seeds, and leave enough that it could be ground and baked into bread for all to taste.

It tasted strange, but good. It was, Schroeder thought, symbolic of a great forward step. It was the first time in generations that any of them had known any food but meat. The corn would make them less dependent upon hunting and, of paramount importance, it was the type of food to which they would have to become accustomed in the future--they could not carry herds of woods goats and unicorns with them on Gern battle cruisers.

The lack of metals hindered them wherever they turned in their efforts to build even the simplest machines or weapons. Despite its dubious prospects, however, they made a rifle-like gun.

The barrel of it was thick, of the hardest, toughest ceramic material they could produce. It was a c.u.mbersome, heavy thing, firing with a flintlock action, and it could not be loaded with much powder lest the charge burst the barrel.

The flintlock ignition was not instantaneous, the lightweight porcelain bullet had far less penetrating power than an arrow, and the thing boomed and belched out a cloud of smoke that would have shown the Gerns exactly where the shooter was located.

It was an interesting curio and the firing of it was something spectacular to behold but it was a weapon apt to be much more dangerous to the man behind it than to the Gern it was aimed at. Automatic crossbows were far better.

Woods goats had been trapped and housed during the summers in shelters where sprays of water maintained a temperature cool enough for them to survive. Only the young were kept when fall came, to be sheltered through the winter in one of the caves. Each new generation was subjected to more heat in the summer and more cold in the winter than the generation before it and by the year one hundred and sixty the woods goats were well on their way toward adaptation.

The next year they trapped two unicorns, to begin the job of adapting and taming future generations of them. If they succeeded they would have utilized the resources of Ragnarok to the limit--except for what should be their most valuable ally with which to fight the Gerns: the prowlers.

For twenty years prowlers had observed a truce wherein they would not go hunting for men if men would stay away from their routes of travel. But it was a truce only and there was no indication that it could ever evolve into friendship.

Three times in the past, half-grown prowlers had been captured and caged in the hope of taming them. Each time they had paced their cages, looking longingly into the distance, refusing to eat and defiant until they died.

To prowlers, as to some men, freedom was more precious than life. And each time a prowler had been captured the free ones had retaliated with a resurgence of savage attacks.

There seemed no way that men and prowlers could ever meet on common ground. They were alien to one another, separated by the gulf of an origin on worlds two hundred and fifty light-years apart. Their only common heritage was the will of each to battle.

But in the spring of one hundred and sixty-one, for a little while one day, the gulf was bridged.
