"Oh, I don't know. I guess it's just getting hard to cope with some of the problems."

"I guess there have been a few."

Jill gave a derisive chuckle. "I sure don't know Greg anymore. Ever since he set up the brewery and the distillery, he Doesn't really want to see me at all."

"Don't take it so hard," Doc comforted. "The strain is showing on all of us. Half the town Docs little more than read or play tapes or drink. Personally, I'd like to know who smuggled the hemp seeds on board."

Jill laughed, which he was glad for, then her face grew serious again. "You know, there'd probably be more trouble if we didn't need someone to look after the kids." She paused, looking up at Doc. "I spend a lot of my time there," she said unnecessarily.

"Why?" It was the first time he'd asked. They bad left the groves and were heading back into town along the gravel road that Greg and Brew and the others had built in better days.

"We . . . I came here for a reason. To continue the human race, to cross a new frontier, one that my children could have a part in. Now, now that we know that the colony is doomed, there's just no motive to anything. No reason. I'm surprised that there isn't more drinking, more carousing and foursomes and divorces and everything else. Nothing seems to matter a whole lot. Nothing at all."

Doc took her by the shoulders and held her. Go on and cry, he silently said to her. G.o.d, I'm tired.

The children grew fast. At nine Eve reached p.u.b.erty and seemed to shoot skyward. She grew more hair. She learned more words, but not many more. She spent much of her time in the trees in the children's complex. The older girls grew almost as fast as she did, and the boys.

Every Sat.u.r.day Brew and Nat took some of the children walking. Sometimes they climbed the foothills at the base of the continental range; sometimes they wandered through the woods, spending most of their efforts keeping the kids from disappearing into the trees.

One Sat.u.r.day they returned early, their faces frozen in anger. Eve and Jerry were missing. At first they refused to discuss it, but when Jase began organizing a search party, they talked.

They'd been ready to turn for home when Eve suddenly scampered into the trees. Jerry gave a whoop and followed her. Nat had left the others with Brew while she followed after the refugees.

It proved easy to find them, and easier still to determine what they were doing with each other when she came upon them.

Eve looked up at Nat, innocent eyes glazed with pleasure. Nat trembled for a moment, horrified, then drove them both away with a stick, screaming filth at them.

Over Nat's vehement objections and Brew's stony refusal to join, Jase got his search party together and set off. They met the children coming home. By that time Nat had talked to the other mothers and fathers at the children's complex.

Jase called a meeting. There was no way to avoid it now, feelings were running too deep.

"We may as well decide now," he told them that night. "There's no question of the children marrying. We could train them to mouth the words of any of our religions, but we couldn't expect them to understand what they were saying. So the question is, shall we let the children reproduce?"

He faced an embarra.s.sed silence.

"There's no question of their being too young. In biological terms they aren't, or you could all go home. In our terms, they'll never be old enough. Anyone have anything to say?"

"Let's have Doc's opinion," a hoa.r.s.e voice called. There was a trickle of supportive applause.

Doc rose, feeling very heavy. "Fellow colonists . . ." The smile he was trying on for size didn't fit his face. He let it drop. There was a desperate compa.s.sion in his voice. "This world will never be habitable to mankind until we find out what went wrong here. I say let our children breed. Someday someone on Earth may find out how to cure what we've caught. Maybe he'll know how to let our descendants breed men again. Maybe this problem will only last a generation or two, then we'll get human babies again. If not, well, what have we lost? Who else is there to inherit Ridgeback?"

"No!" The sound was a tortured meld of hatred and venom. That was Nat, loving mother of six, with her face a strained mask of frustration. "I didn't risk my life and leave my family and, and train for years and bleed and sweat and toil so my labor could fall to. . . to... a bunch of G.o.dd.a.m.ned monkeys!"

Brew pulled her back to her seat, but by now the crowd was muttering and arguing to itself. The noise grew louder. There was shouting. The yelling, too, grew in intensity.

Jase shouted over the throng. "Let's talk this out peacefully!"

Brew was standing, screaming at the people who disagreed with him and Natalie. Now it was becoming a shoving match, and Brew was getting more furious.

Doc pushed his way into the crowd, hoping to reach Brew and calm him. The room was beginning to break down into tangled knots of angry, emotionally charged people.

He grabbed the big man's arm and tried to speak, but the Swede turned bright baleful eyes on him and swung a heavy fist.

Doc felt pain explode in his jaw and tasted blood. He fell to the ground and was helped up again, Brew standing over him challengingly. "Stay out of our lives, Doctor," he sneered, openly now. "You've never helped anything before. Don't try to start now."

He tried to speak but felt the pain, and knew his jaw was fractured. A soft hand took his arm and he turned to see Elise, big green eyes luminous with pity and fear. Without struggling, he allowed her to take him to the ship infirmary.

As they left the auditorium he could hear the shouting and struggling, Jase on the microphone trying to calm them, and the coldly murderous voices that screamed for "no monkey Grandchildren."

He tried to turn his head towards the distant sound of argument as Elise set the bone and injected quick-healing serums. She took his face and kissed him softly, with more affection than she had shown in months, and said, "They're afraid, Harry." Then kissed him again, and led him home.

Doc raged inwardly at his jaw that week. Its pain prevented him from joining in the debate which now flared in every corner of the colony.

Light images swam across his closed eyes as the sound of fists pounding against wood roused him from dreamless sleep. Doc threw on a robe and padded barefoot across the cool stone floor of his house, peering at the front door with distaste before opening it. Jase was there, and some of the others, somber and implacable in the morning's cool light.

"We've decided, Doc," Jase said at last. Doc sensed what was coming.

"The children are not to breed. I'm sorry, I know how you feel-" Doc grunted. How could Jase know how he felt when lie wasn't sure himself? "We're going to have to ask you to perform the sterilizations . . ." Doc's hearing faded down to a low fuzz, and he barely heard the words. This is the way the world ends. .

Jase looked at his friend, feeling the distaste between them grow. "All right. We'll give you a week to change your mind. If not, Elise or Greg will have to do it." Without saying anything more they left.

Doc moped around that morning, even though Elise swore to him that she'd never do it. She fussed over him as they fixed breakfast in the kitchen. The gas stove burned methane reclaimed from waste products, the flame giving more heat control than the microwaves some of the others had. Normally Doc enjoyed scrambling eggs and woking fresh slivered vegetables into crisp perfection, but nothing she said or did seemed to lift him out of his mood.

He ate lightly, then got dressed and left the house. Although she was concerned, Elise did not follow him.

He went out to the distillery, where Greg spent much of his time under the sun, drunk and playing at being happy. "Would you?" The pain still m.u.f.fled Doc's words. "Would you sterilize them?"

Greg looked at him blearily, still hung over from the previous evening's alcoholic orgy. "You don't understand, man." There was a stirring sound from the sheltered bedroom behind the distillery, and a woman's waking groan. Doc knew it wasn't Jifi. "You just don't understand."

Doc sat down, wishing he had the nerve to ask for a drink. "Maybe I don't. Do you?"

"No. No, I don't. So I'll follow the herd. I'm a builder. I build roads, and I build houses. I'll leave the moralizing to you big brains."

Doc tried to say something and found that no words would come. He needed something. He needed .

"Here, Doc. You know you want it." Greg handed him a canister with a straw in it. "Best d.a.m.n vodka in the world." He paused, and the slur dropped from his voice. "And this is the world, Doc. For us. For the rest of our lives. You've just got to learn to roll with it." He smiled again and mixed himself an evil-looking drink.

Greg's guest had evidently roused herself and dressed. Doc could hear her now, singing a s.n.a.t.c.h of song as she left. He didn't want to recognize the voice.

"Got any orange juice?" Doc mumbled, after sipping the vodka.

Greg tossed him an orange. "A real man works for his pleasures."

Doc laughed and took another sip of the burning fluid. "Good lord. What is that mess you're drinking?"

"It's a Black Samurai. Sake and soy sauce."

Doc choked. "How can you drink that?"

"Variety, my friend. The stimulation of the bizarre."

Doc was silent for a long time. Senses swimming he watched the sun climb, feeling the warmth as morning melted into afternoon. He downed a slug of his third screwdriver and said irritably, "You can't do it, Greg. If you sterilize the children, it's over."

"So what? It's over anyway. If they wanna let a drunk slit the pee pees of their . . . shall we say atavistic progeny? Yeah, that sounds nice. Well, if they want me to do it, I guess I'll have to do it." He looked at Doc very carefully. "I do have my sense of civic duty. How about you, Doc?"

"I tried." He mumbled, feeling the liquor burning his throat, feeling the light-headedness exert its pull. "I tried. And I've failed."

"You've failed so far. What were your goals?"

"To keep.-" he took a drink. d.a.m.n, that felt good. "To keep the colony healthy. That's what. It's a disaster. We're at each other's throats. We kill our babies-"

Doc lowered his head, unable to continue.

They were both silent, then Greg said, "If I've gotta do it, I will, Doc. If it's not me, it'll be someone else who reads a couple of medical texts and wants to play doctor. I'm sorry."

Doc sat, thinking. His hands were shaking. "I can't do that." He couldn't even feel the pain anymore.

"Then do what you gotta do, man," and Greg's voice was dead sober.

"Will you . . . can you help me?" Doc bit his lip. "This is my civic duty, you know?"

"Yea, I know." He shook his head. "I'm sorry. I wish I could help."

A few minutes pa.s.sed, then Doc said drunkenly, "There's got to be a way. There just has to be."

"Wish I could help, Doc."

"I wish you could too," Doc said sincerely, then rose and staggered back to his house.

It rained the night he made his decision, one of the quick, hot rains that swept from the coast to the mountains in a thunderclap of fury. It would make a perfect cover.

He gathered his medical texts, a Bible and a few other books, regretting that most of the information available to him was electronically encoded. Doc took one of the silent stunners from the armory. The non lethal weapons had only been used as livestock controllers. There had never been another need, until now. From the infirmary he took a portable medical kit, stocking it with extra bandages and medicine, then took it all to the big cargo flyer.

It was collapsible, with a fabric fuselage held rigid by highly compressed air in fabric structural tubing. He put it in one of the soundless electric trucks and inflated it behind the children's complex.

There was plenty of room inside the fence for building and for a huge playground with fruit trees and all the immemorial toys of the very young. After the children had learned to operate a latch, Brew had made a lock for the gate and given everyone a key. Doc clicked it open and moved in.

He stayed in the shadows, creeping close to the main desk where Elise worked.

You can't follow where I must go, he thought regretfully. You and I are the only fully trained medical personnel You must stay with the others~ I'm sorry, darling.

And he stunned her to sleep silently, moving up to catch her head as it slumped to the table. For the last time, he gently kissed her mouth and her closed eyes.

The children were in the left wing-one room for each s.e.x, with floors all mattress and no covers, because they could not be taught to use a bed. He sprayed the sound waves up and down the sleeping forms. The parabolic reflector leaked a little, so that his arm was numb to the elbow when he was finished. He shook his hand, trying to get some feeling back into it, then gave up and settled into the hard work of carrying the children to the flyer.

He hustled them through the warm rain, bending under their weight but still working swiftly. Doc arranged them on the fabric floor in positions that looked comfortable-the positions of sleeping men rather than sleeping animals. For some time he stood looking down at Jerry his son and at Lori his daughter, thinking things he could not afterwards remember.

He flew North. The flyer was slow and not soundless; it must have awakened people, but he'd have some time before anyone realized what had happened.

Where the forest had almost petered out he hovered down and landed gently enough that only a slumbering moan rose from the children. Good. He took half of them, including Jerry and Lori, and spread them out under the trees. After he had made sure that they had cover from the air he took the other packages, the books and the medical kit, and hid them under a bush a few yards away from the children.

He stole one last look at them, his heirs, small and defenseless, asleep. He could see Elise in them, in the color of their hair, as Elise could see him in their eyes and cheeks.

Kneading his shoulder, he hurried back to the ship. There was more for him to do.

Skipping the ship off again, he cruised thirty miles west, near the stark ridge of mountains, their somber gray still broken only spa.r.s.ely by patches of green. There he left the other seven children. Let the two groups develop separately, he thought. They wouldn't starve, and they wouldn't die of exposure, not with the pelts they had grown. Many would remain alive, and free. He hoped Jerry and Lori would be among them.

Doc lifted the flyer off and swept it out to the ocean. Only a quarter mile offsh.o.r.e were the first of the islands, lush now with primitive foliage. They spun beneath him, floating brownish-green upon a still blue sea.

Now he could feel his heartbeat, taste his fear. But there was resolve, too, more certain and calm than any he had known in his life.

He cut speed and locked the controls, setting the craft on a gradual decline. Shivering already, he pulled on his life jacket and walked to the emergency hatch, s.c.r.e.w.i.n.g it open quickly.

The wind whipped his face, the cutting edge of salt narrowing his eyes. Peering against the wall of air pressure he was able to see the island coming up on him now, looming close. The water was only a hundred feet below him, now eighty, sixty .

The rumbling of the shallow breakers joined with the tearing wind, and, fighting his fear, he waited until the last possible moment before hurling himself from the doorway.

He remembered falling.

He remembered hitting the water at awful speed, the spray ripping into him, the physical impact like the blow of a great hand. When his head broke surface Doc wheezed for air, swallowed salty liquid and thrashed for balance.

In the distance, he saw the flash of light, and a moment later heard the shattering roar as the flyer spent itself on the rocky sh.o.r.e.

Jase was tired. He was often tired lately, although he still managed to get his work done.

The fields had only recently become unkempt, as Marlow and Billie and Jill and the others grew more and more inclined to pick their vegetables from their backyard gardens.

So just he and a few more still rode out to the fields on the tractors, still kept close watch on the herds, still did the hand-pruning so necessary to keep the fruit trees healthy.

The children were of some help. Ten years ago a few of them had been captured around the foothill area. They had been sterilized, of course, and taught to weed, and carry firewood, and a few other simple tasks.

Jase leaned on his staff and watched the s.h.a.ggy figures moving along the street, sweeping and cleaning.

He had grown old on this world, their Ridgeback. He regretted much that had happened here, especially that night thirty-some years before when Doc had taken the children.

Taken them-where? Some argued for the islands, some for the West side of the mountain range. Some believed that the children had died in the crash of the flyer. Jase had believed that, until the adult Piths were captured. Now, it was hard to say what happened.

It was growing chill now, the streetlights winking on to brighten the long shadows a setting Tau Ceti cast upon the ground. He drew his coat tighter across his shoulders and walked back to his house. It was a lonelier place to be since June had died, but it was still home.

Fumbling with the latch, he pushed the door open and reached around for the light switch. As it flicked on, he froze.

My G.o.d.

"h.e.l.lo, Jase." The figure was tall and spare, clothes ragged, but graying hair and beard cut squarely. Three of the children were with him.

After all this time .

"Doc . . ." Jase said, still unbelieving. "It is you, isn't it?"
