t going to get rich in a matter of days, that the first vein had been a fluke. Not that there weren't fortunes contained in the asteroid belt. There was enough gold and platinum metals and silver to make her one of the richest people in the U.P., but it wasn't going to be all that easy. The Mother Lode wasn't going to go home laden with nuggets of pure gold, but she would go back with very, very rich ore filling all available cargo spaces. Heck, it might even take two or three trips out there to make her as rich as she decided she wanted to be. She started loading gold-rich ore. It was picky work. First the areas containing gold had to be searched out by instrument, then Mother had to be positioned. The ship couldn't sit on a needle point of rock, so some very rich sounding areas had to be bypassed in order to find a fairly flat landing place. Moving in and out of the tumbling, crowded asteroid belt ceased to be so thrilling she could hardly stand it and came to be just spine-tinglingly terrifying. She'd been working for just under a month when she decided to scout around a bit before attaching the ship to another asteroid. She circled the sun in an orbit outside the belt. The density of the belt was about equal all the way around. She saw chunks that were large enough to make fairly respectable moons for a small planet. She had forgotten her loneliness. She had her work. She had very good company. Mop was not demanding. He fed and watered himself by pushing on his Mop buttons at his station. He had been trained to use an ingenious little pad in the exercise room that broke his body wastes down into recyclable liquids immediately and pulled the smells in behind them. He didn't talk a lot. In fact, except for that meaningful grunt which said, «Please, Erin, rub my belly,» he'd been silent since his disturbed howling had chilled Erin. On the opposite side of the orbital ring of debris she jockeyed Mother down onto a flat surface, stabilized the tumble, put out the extractor arm, and began to load ore that was the richest she'd seen since the first day. The detectors were humming merrily about gold and she was humming a little song that had been rewritten with some rather ribald lyrics by the junior officers aboard Rimfire. She was just about ready to knock off for the day when there was a clear tone, a vibrant, piercing tone that jerked her to attention. She stopped the movement of the arm and focused a viewer on the biter at the end. The vibrant, piercing tone of alert continued to sing in her ears. She saw something a bit lighter in color than the gold bearing rock, reached back to kill the foreign object alert, turned on a powerful light, lowered the viewer until its nozzle almost touched the biter at the end of the extractor arm. «Woah,» she whispered. All around her was the vacuum of space, the coldness and emptiness, the uncaring, glaring stars. The nearest planet, a bit larger than New Earth, was a chemical swamp with surface temperatures hot enough to ignite paper, if there'd been any oxygen in the poisonous atmosphere. Nearer the sun were the two cinder planets, lifeless rock baked by the solar storms. Far away, out past the chemical swamp planet, was a frozen, airless ball of ice. And at the tip of the excavator arm, still half encased in the matrix rock, was a fossilized skull, a skull that looked up at her with dark, eyeless sockets, a skull that had to be incredibly ancient, and was very damned definitely humanoid. Man had been twice in space. A very few had soared upward from Old Earth on the fire of primitive chemical rockets. Centuries later man had broken the bounds of planetary gravity once more, this time with the help of old Billy Bob Blink's invention that made star travel less dangerous and much less time-consuming. Man had been in space for the second time for thousands of years and in all that time he had encountered intelligence only in the mutated forms of life that had survived the Destruction of Old Earth. He had found evidence of alien intelligence, but the aliens were all dead—the residents of the Dead Worlds and the two races who clung together in a clasp of death as galaxies collided in Cygnus. The decades of work on Old Earth since the reunion had taught man much about himself. From her classes at the Academy Erin knew that life on Old Earth had begun millions of years in the past, but that man, himself, was a relative newcomer. The humanoid skull staring up at her with its blank, dark eyes was as old or older than the anthropoid remains that had been discovered in fossil form on Old Earth since the reunion. Here, then, was evidence of another manlike race. Whether or not the skull represented intelligence she could not guess, but she knew that X&A scientists would consider it to be of more importance than the gold and gold ore she had stowed in Mother's bins. She moved the extractor arm slightly. The skull was still attached to the matrix rock. «Well, damn,» she said. Mop looked up questioningly. «I can't believe I'm going to do this,» she said. Mop followed her to the air lock and watched anxiously as she worked her way into a suit. «Sorry, fella, this trip isn't for you,» she said. She took the dog to the control room, closed the door behind her, felt panic for one moment not because she was scared, but because if anything happened to her out there, Mop would be left all alone to punch out his food and water until it was all gone and then— «Oh, damn,» she moaned, as she closed the helmet and sucked air. «Oh, shit,» she said, as the inner hatch closed and a pump whined as it evacuated air from the lock. «Balls,» she whispered, as the outer hatch opened and she stared out into the big empty. CHAPTER FOUR She felt stiff and heavy as she stepped out of the hatch onto the ship's ladder. She could never get enough oxygen into her lungs while she was imprisoned inside a flexsuit. The feeling of being slowly suffocated was psychological, for the air mixture in the suit was richer than that aboard ship. She halted for a moment before turning around to adjust the tool kit strapped to her back. The hatch started to close behind her. She did not hear it, of course, but she felt the slight vibration of its movement coming up through her boots. She turned and was mesmerized as the opening narrowed. When the crack closed and the hatch snugged itself into its seal, she felt panic. What if? What if the hatch lock didn't respond to her instructions when she was ready to go back into the ship? She had only a few hours of air. With the oxygen gone, she would never decay. She would be held on the surface of the asteroid by the field of the ship's generator until, perhaps years from now, the generator used up its full charge and cooled. Would she then drift away from the rock to tumble free in her own eternal orbit around an alien sun? She had performed extravehicular work before, but never alone. There had been times when teams of crewmen in suits had swarmed over the outside hide of Rimfire to check her condition, but each man had been teamed with another. Every spacer who had faced the void knew the devastating effect of looking at the big empty through an impossibly frail faceplate from the doubtful security of a flexsuit. It was S.O.P. to never, never, send a man outside the ship without a buddy. There near the core, with legions, hoards, multitudes of brilliant stars surrounding her, she felt more isolated than she had felt while space walking in the nothingness outside the galaxy when she had to look in one direction to see the misty mass of the Milky Way, when there was nothing but blankness on three sides. She was dwarfed. She felt as if she were being infinitely diminished. She turned and with a shaking hand punched the entry combination into the lock. The hatch began to open. She took a deep breath and let it out, canceled the open order, turned her face up toward the viewport in the control room. She saw the shaggy face of Mop. His sharp nose and alert eyes followed her movement as she climbed down the ladder. She waved and said, «Hold the fort, buddy. I'll be back before you know it.» The Mother Lode was in harsh sunlight. The surface of the asteroid was not level so that the ship seemed to be tilted. From the inside the lopsided stance had not mattered, since the reference for the senses was the ship's own gravity which made her deck down regardless of her position. Standing outside, the breath of the nuclear furnace that was the nearest star raising the temperature on the surface of her suit, Erin felt momentary dizziness as she looked up at Mother. She took a deep breath. The hiss of air was loud inside her helmet. On all sides around her the shattered remnants of a world kept pace, most of them tumbling slowly. She was in the middle of an eerie sea of motion made up of the glaring, brutal, unfiltered sunlight reflecting off sunward planes and angles and the absolute blackness of space that was echoed on the dark sides of the asteroids. And over and under and to all sides were the cold, many-faceted faces of the core star fields. In the shadow of the ship the suit's coolers changed tone as their function was reversed to heating. The light attached to her helmet came on automatically. She pointed it by moving her head, approached the extraction arm, stepped down into the trench. It was pleasing to her to see the light bouncing off flecks of pure gold, but that pleasure passed when she focused her attention on the thing that was partially exposed near the biting end of the arm. She placed the work kit on the barren stone, removed a hand-held, laser powered cutter, a tool developed especially for mining. A sensor guided her to a setting that would not harm the fossil bone. She applied the laser to the matrix rock around the skull experimentally, saw that the setting was perfect. The enclosing rock melted away. For a few minutes she forgot her appalling isolation, did not lift her eyes to see the harsh sunlight or the crowded stars, concentrated on the job at hand until she could lift the skull free. She placed it on the rock at the side of the trench and cleaned it with the laser beam. She had not been wildly interested in the subject matter covered in the one course in paleontology that had been required at the Academy. Following the fossil record of the evolution of the Tigian tiger was, at best, dull. Only a few days had been allocated to the discussion of the work being done by technicians in anti-radiation gear on Old Earth, where the hardened remains of the Old Ones, man himself, were being unearthed. Before going extravehicular, she had punched in orders for the scant material on the development of man. The skulls of the Old Ones, Earthmen, were identical to those of modern man. This had inspired various interpretations. One cynical school of thought had it that God had given up on man, that after the Destruction He had determined that man was His greatest failure and had abandoned any further development. Others, more upbeat, believed that, as the Bible said, man had been created in God's image, and was thus perfect, needing no evolution from the form that had been developed prior to the Destruction. The mutation of the Old Ones into Healers, Power Givers, Far Seers, and Keepers after the Destruction was, depending on one's viewpoint: 1. The power of God exemplified, since divine miracles were required to preserve life on earth. 2. The work of the evil one, perverting the perfection of God's finest creation into ugly and malignant forms. Fortunately, the first view, or more moderate adaptations of it, prevailed in U.P. society, allowing the mutants from Old Earth to be valued and welcome members of the race. But the fossil skull that grinned at her, all teeth intact, eye sockets black and empty, was not that of some mutated form or of some alien. Her knowledge was limited. She was not an expert in the field, but she'd looked at pictures just minutes before exiting the ship and the images were fresh in her mind. This fellow had been the guy next door. He was man. Modern man. And that was very damned interesting since, if she remembered correctly, it took a few million years to turn living bone into stone. She used the mining laser to check the area where the skull had spent an eon in sleep. She melted out a lightning bolt of pure gold and held it in her hand, but there was no sign of other fossilized bones. Mother spoke to her. The husky voice of the computer said, «You have been extravehicular for one hour and twenty-eight minutes.» No problem. She had four hours worth of air and a ten minute reserve. She melted out another small vein of gold, put it into her specimen pouch, examined the rock near the trench, said, «Well, to hell with it.» The suit's coolers sizzled into action as she stepped back into the light. She looked up and around. The skull in the pouch on the outside of the flexsuit pressed against her thigh as if reminding her that once it had housed the soft, mysterious things that made up an intelligent brain. The stars pushed down, dazzling her eyes. The tumbling rocks of the asteroid belt seemed to be moving toward her. She ran in pure panic, clambered up the steps, mispunched the combination to the lock, screamed out good, solid, spacer profanity that had originated in the less desirable areas of a score of planets. Her frantic eyes looked up, saw Mop sitting on the little ledge of the control room viewport, his mouth open, his tongue hanging out. «Hi,» she said, calming enough to punch the right combination into the lock. The outer hatch closed with an unheard but felt clang. Air hissed into the lock. The inner door opened and she peeled out of the suit, first removing the two samples of gold and the skull from the outside pouches. «Well, my friend,» she said, holding the skull in both hands, for it was, after all, heavy stone. «I can't say I care too much for the garden spot where you decided to spend eternity.» She was just a little bit ashamed of herself. Mop greeted her as if she'd been gone for ages, leaping, making mock attacks, hoisting his rear and lowering his head between his front paws in his «look-at-me-I'm-charming» pose. She ruffled his soft hair, picked him up. He threw himself over onto his back in the crook of her arm with a gusty sigh and allowed her to rub his chest and belly. When he had had enough he began to wiggle. She put him down, punched up a very stiff drink, sat in the control chair. Mop took his place on the console and lay down, his head held up alertly, ready for conversation. «Mr. Mop,» she said, «looks to me as if this belt of rock was once a planet of considerable size.» Mop said, «Wurf.» «Which makes you think, doesn't it?» She took a long sip of her drink. «The U.P.'s planet buster could have done this to a planet. Did, as a matter of fact, to a few Zede worlds during the Zede War, but that was just a thousand years ago, and our friend, there—» she shifted her eyes to the skull—» is very damned definitely more than a thousand years old.» Mop lifted his right paw, asking for a handshake. She complied, held the paw. «What we should do, I guess, is send a blinkstat back to X&A right now.» Mop cocked his head. «Yeah, you're right,» she said. «We've got everything we own tied up in this expedition. Dad's money, too. Everything wrapped up in this Mother. I don't know how much gold we've got aboard, but I do know this. We report our friend, here, to X&A and this whole belt will be off bounds until it's searched for other fossils. That means that you and I wouldn't live long enough to get back to digging gold.» She had released Mop's paw. He scratched her hand gently, demanding her touch. She held his paw again. «What I think is this,» she said. «I think we will wait to mine this particular rock. What I mean, sir, is this.» Mop cocked his head. «We haven't even seen this rock, have we?» Mop didn't say anything. «If you ever want me to take you go—» His right ear shot up. «—you'd better agree with me.» «Wurf,» he said. «Good,» she said, nodding. «And we won't see it until we're good and damned ready to see it, will we? If you ever want to go?» «Wurf,» Mop said. «Because our friend there has waited an eon or two already. I think he can wait until a nice, deserving young girl and a rather splendid pooch are so rich that the U.P. tax men can't take it all away from us.» She picked Mop up and ruffled the blond hair on his head. «So rich that waiters will bow and shop women will give us shit-eating grins. So rich that we'll buy you a diamond-studded collar. Would you like that?» «Ummmmm,» Mop said, meaning, «rub my belly, Erin.» She had to go back out again to place a coded beeper in the trench
