Jherek Carnelian sat at the far end of the dormitory, a bowl of bread and milk in his lap, an expression of hopeless misery upon his face, while Nurse stood by the door saying goodnight.

"I really should point out, Nurse, that, since your closed environment has been entered by an outsider, a variety of temporal paradoxes are likely to take place. They are sure to disrupt your way of life and mine probably much more than we should want."

"Sleepy time now," said Nurse firmly, for the sixth time since Jherek had arrived. "Lights out, my little men!"

Jherek knew that it was useless to get up once he had gone to bed. Nurse would detect him immediately and put him back again. At least it was easy to know how long he had been here. Each day measured exactly twenty-four hours and each hour had sixty-minutes — it was all on the old non-malleable reckonings. The Age of the Tyrant Producers would have been one of the last to use them.

Jherek knew that Nurse must have been programmed to act upon new information and to deal with it intelligently, but she had become sluggish over the centuries. His only hope was to keep insisting on what was self-evident truth, but it could take months. He wondered how the Iron Orchid and the others had fared on the surface. With any luck, when he was able to escape, he would find the Lat weapons neutralized (it was quite easy to do and had been done on several previous occasions) and the aliens returned to space.

"I think you should consider a re-programming, Nurse!" Jherek called into the darkness.

"Now, now, Jerry, you know I disapprove of cheeky children." The door closed. Nurse rolled away down the corridor.

Jherek wondered if he had been right in believing that he had detected a faint uncertainty's in Nurse's voice tonight.

Freddie Fearless said admiringly from the next bed. "You can certainly keep it up, can't you Jerry? I don't know why the old girl lets you get away with it."

"Perhaps, in her subconscious, she realizes that I'm an adult and doesn't like to admit it," Jherek suggested.

This drew a ripple of laughter from the boys.

"That's Jerry Jester," said Dick Dreadnought, "always playing the fool! Life wouldn't be nearly so much fun without you, Jerry." Like the others, he had accepted Jherek immediately and seemed to have forgotten that he had only recently entered the nursery.

With a sigh, Jherek turned over and tried to operate his power rings, as he had taken to doing every night, but plainly some protective device in the nursery blocked off the source of their energy. He still had the deceptor-gun, but he couldn't think of any use for it at present. He felt under his pillow. It was still there. With a sigh, he tried to go to sleep. It seemed to him that he was in an even more uncomfortable situation than when he had been Snoozer Vines' prisoner in Jone's Kitchen in 1896. He remembered that there, too, they had called him Jerry. Did all gaolers favour that name for him?

Jherek wakened and was surprised that the lights were not on, as they usually were; also he could not smell breakfast; moreover Nurse was not standing by the door ringing her bell and calling "Wake up, sleepyheads!" as was her wont.

From somewhere beyond the dormitory, however, there came various noises — yells, explosions, screams and bangs — and suddenly the door had sprung open, admitting light from the corridor.

"Berchoos ek!" said a familiar voice. "Hoody?"

And Captain Mubbers, his whiskers bristling, his musical instrument in his hands, stood framed in the doorway. He glared at Jherek.

"Kroofrudi!" he said in recognition, and a nasty grin appeared on his face.

Jherek groaned. The Lat had found him and now the children were in danger.

"Ferkit! Jillip goff var heggo heg, mibix?"

"I still can't understand you, Captain Mubbers," Jherek told the brigand-musician. "However, I take it you would like me to accompany you and, of course, I shall. Hopefully you will then leave the rest of — I mean — leave the children alone." With as much dignity as he could muster considering he was wearing a jacket and trousers of brightly striped flannel far too small for him, he rose from his bed, his hands in the air, and walked towards the Lat captain.

Captain Mubbers snorted with mirth. "Shag uk fang dok pist kickle hrunt!" he yelled. His men gathered around him and they, too, joined in their leader's merriment. One even dropped his weapon, but was quick to recover it again. This made Jherek wonder if their own power source came from their spaceship or if the weapons, like his deceptor-gun, had independent cells. He supposed that there wasn't any easy way of finding out. He bore their laughter as manfully as he could.

Captain Mubbers' bulbous nose fairly glowed with the strain of his laughter. "Uuuungh, k-k-kroofrudi! Uuuuuungh, k-kroofrudi!"

"What's this? What's this? More naughty boys from outside!" came Nurse's booming voice from down the corridor. "And during the night, now! This will never do!"

Captain Mubbers and his men looked at one another with expressions of disbelieving surprise on their faces. Nurse rolled steadily on.

"You are nasty rough boys and you are disturbing my charges. Haven't you homes to go to?"

"Kroofrudi!" said Captain Mubbers.

"Ferkit!" said another.

"Ugh! Disgusting!" said Nurse. "Where do you pick up such words!"

Captain Mubbers stepped to the head of his gang and menaced Nurse with his instrument. She ignored it completely. "I have never seen such filthy little boys. And what have you got in your hands?

Catapults, no doubt!"

Captain Mubbers aimed his instrument at Nurse and pulled the trigger. Howling fire left the muzzle and struck Nurse full on her chest. She made a fussy, brushing motion, then one of her arms extended and she snatched the instrument from Captain Mubbers' grasp.

"Naughty, naughty, naughty, little boy. I will not have such behaviour in the nursery!"

"Olgo glex mibix?" said Captain Mubbers placatingly. He tried to smile, but his eyes were glassy as he stared up at Nurse whose huge metal head looked down upon him. "Frads kolek goj sako!"

"I will listen to no more of your nastiness. This is the only way to teach manners to the likes of you, young man."

With great satisfaction, Jherek watched as Captain Mubbers was snatched yelling into the air, was thrown across Nurse's knee, was divested of his trousers and slapped soundly upon his bare and unlovely backside. Captain Mubbers shouted to his crew to help and they all began kicking at Nurse, tugging at her, swearing at her, to no avail. Sedately she completed the punishment of Captain Mubbers and then, one by one, gave similar treatment to his companions, confiscating their instruments at the same time.

Chastened, they all stood holding their bottoms, red-faced and tearful, while Jherek and the boys from the dormitory laughed delightedly.

Nurse began to roll down the corridor with an armful of alien instruments. "You may have these back only when you leave the nursery," she said. "And you will not leave the nursery until you have learned some manners!"

"Kroofrudi," said Captain Mubbers, glowering at the disappearing robot, but he spoke the word softly, nervously, more from bravado than anything else. "Hrunt!"

Jherek felt almost sorry for the Lat, but he was glad that the children were safe.

"I heard you!" Nurse called chidingly. "I shan't forget!"

Captain Mubbers caught her drift. He said no more.

Jherek grinned. It pleased him more than he would have guessed to see the Lat brought so low.

"Well," he said, "we're all in the same kettle of fish now, eh?"

"Mibix?" queried Captain Mubbers in a small, defeated voice.

"However, the idea of spending the same week, recycled through eternity, in the company of children, Lat and a senile robot is not entirely appealing," said Jherek, in a critical and miserable mood for him. "I really must think how I'm to effect my escape and achieve a reconciliation with Mrs. Amelia Underwood."

Captain Mubbers nodded. "Greef cholokok," he said, by way of affirmation.

Nurse was returning. "I've locked your toys away," she told Captain Mubbers and the others. "And now it's straight to bed without any supper. Have you any idea how late it is?"

The Lat stared at her blankly.

"My goodness, I do believe they've sent me a party of mentally subnormals!" exclaimed Nurse. "I thought they were going to be left behind to placate Pecking Pa." She pointed at the row of empty beds down one side of the dormitory. "In there," she said slowly. "Bed."

The Lat shuffled towards the beds and stood looking stupidly down at them.

Nurse sighed and picked up the nearest alien, stripping off his clothing and plumping him down, pulling the bedding over his shivering body. The others hastily began to pull off their own clothes and climbed into bed.

"That's more like it," said Nurse. "You're learning." She turned her hard, blue eyes on Jherek.

"Jerry, I think you'd better come to my sitting room. I'd like a word with you now."

Meekly, Jherek followed Nurse down the corridor and into a room whose walls were covered in flock wallpaper, with landscape paintings and little ornaments. Elsewhere was a great deal of chintz and gingham. It reminded Jherek vaguely of the house he had furnished for Mrs. Amelia Underwood.

Nurse rolled to one corner of the room. "Would you like a cup of tea, Jerry?"

"No thank you, Nurse."

"You are probably wondering why I asked you here, when it's long past your bedtime."

"It had occurred to me, Nurse, yes."

"Well," she announced, "my creative-thinking circuits are beginning to come back into play. I think.

I've become rather set in my ways, as old robots will, particularly when involved in a temporal recycling operation like this one. You follow me?"

"I do indeed."

"You are older than the other children, so I think I can talk to you. Even," Nurse made an embarrassed rumbling sound somewhere inside her steel chest, "even ask your advice. You think I've become a bit of a stick in the mud, don't you?"

"Oh, not really," Jherek told her kindly. "We all develop habits, over the millennia, which are sometimes hard to lose when we no longer need them."

"I have been thinking about one or two things which you've said this past week. You've been to the surface, evidently."

"Um…"

"Come now, lad, tell the truth. I shan't punish you."

"Yes, I have, Nurse."

"And Pecking Pa is dead?"

"And forgotten." Jherek wriggled uncomfortably in his too-tight pyjamas. "It's been thousands of years since the Age of the Tyrant Producers. Things are much more peaceful these days."

"And these outsiders — they are from the outside time-phase?"

"They are, more or less."

"Which means that paradoxes begin to occur, if we're not careful."

"I gather so, from what I have been told about the nature of Time."

"You've been informed correctly. It means that I must think very carefully now. I knew this moment would come eventually. I have to worry about my children. They are all I have. They are the Future."

"Well, the Past, at least," said Jherek.

Nurse glared sternly at him. "I'm sorry, Nurse," he said. "That was facetious of me."

"My duty is to take them into an age where they will be in no danger," Nurse continued. "And it seems that we have reached that age."

"I am sure they will be very welcome in my society," Jherek told her. "I and one other are the only ones who have been children. My people love children. I am proof of that."

"They are gentle?"

"Oh, yes, I think so. I'm not quite sure of the meaning — you use words which are archaic to me — but I think 'gentle' is a fair description."

"No violence?"

"There you've lost me altogether. What is 'violence'?"

"I'm satisfied for the moment," said Nurse. "I must be grateful to you, Jerry Jester. For all that you are always acting the fool, you're made of decent stuff underneath. You've reawakened me to my chief responsibilities." Nurse seemed to simper (as much as a robot could simper). "You are my Prince Charming, really. And I was the Sleeping Beauty. It would seem that the danger to the children is over and they can be allowed to grow normally. What sort of conditions exist in the outside world? Will they find good homes?"

"Any kind they wish," said Jherek.

"And the climate. Is it good?"

"Whatever one cares to make it."

"Educational facilities?"

"Well," he said, "I suppose you could say that we believe in self-education. But the facilities are excellent. The libraries of the rotted cities are still more or less intact."

"Those other children. They seemed to know you. Are they from your time?" It was plain that Nurse was becoming increasingly intelligent with every passing second.

"They are aliens from another part of the galaxy," Jherek said. "They were chasing me and some of my friends." He explained what had happened.

"Well, they must be expelled, of course," said Nurse, having listened gravely to his account.

"Preferably into another period of time where they can do no more harm. And here normal time must replace recycled time. That is merely a question of stopping a process…" Nurse sank into a thoughtful silence.

Jherek had begun to hope. "Nurse," he said. "Forgive me for interrupting, but am I to understand that you have the power to pass people back and forth in Time?"

"Back is very difficult — they are not inclined to stick, in my experience. Forth is much easier.

Recycling is," a mechanical chuckle sounded in her throat, "child's play, as it were."

"So you could send me back, say, to the 19th century?"

"I could. But the chances of your staying there for long are poor…"

"I'm aware of the theory. We call it the Morphail Effect in this age. But you could send me back."

"I could, almost certainly. I was programmed specifically for Time Manipulation. I probably know more about it than any other being."

"You would not have to use a time machine?"

"There's a chamber in this complex, but it would not be a machine which moved physically through time. We've abandoned such devices. As a matter of fact, time travel itself, being so uncertain, was pretty much abandoned, too. It was only in order to protect the children that we built this place."

"Would you send me back, Nurse?"

Nurse seemed hesitant. "It's very dangerous, you know. I know that I owe you a favour. I feel stupid for having forgotten my duty. But sending you so far back…"

"I have been before, Nurse. I'm aware of the dangers."

"That's as may be, young Jerry Jester. You were always a wild one — though I could never be as firm with you as I should have been. How I used to laugh, privately, here in my little sitting room, at your antics, at the things you said…"

"Nurse! I think you're slipping again," Jherek warned her.

"Eh? Put another lump of coal on the fire, would you my boy?"

Jherek looked around, but could see no fire.

"Nurse?"

"Aha!" said Nurse. "Send you to the 19th century. A long time ago. A long, long time ago. Before I was born. Before you were born, that's for certain. In those days there were oceans of light and cities in the skies and wild flying beasts of bronze. There were herds of crimson cattle that roared and were taller than castles. There were shrill…"

"To 1896 to be precise, Nurse. Would you do it for me? It would mean a great deal."

"Magics," she continued, "phantasms, unstable nature, impossible events, insane paradoxes, dreams come true, dreams gone awry; nightmares assuming reality. It was a rich time and a dark time…"

"1896, Nurse."

"Ah, sometimes, in my more Romantic moments, I wish that I had been some merchant governess; some great lady of Hong Kong, trading capital of the world, where poets, scholars and soldiers of fortune all congregated. The ships of a hundred nations at anchor in the harbours. Ships from the West, with cargoes of bearskins and exotic soaps; ships from the South, with crews of dark-visaged androids, bearing bicycles and sacks of grit; ships from the East…"

"Plainly we share an interest in the same century," said Jherek desperately. 'Do not deny me my opportunity to go back there, dear Nurse."

"How could I?" Her voice had become almost inaudible, virtually soft as nostalgia seized her. At that moment, Jherek felt a deep sympathy for the old machine; it was rare that one was privileged to witness the dream of a robot. "How could I refuse my Jerry Jester anything. He has made me live again."

"Oh, Nurse!" Jherek was moved to tears. He ran forward and hugged the rigid body. "And with your help I, too, shall come to life again!"
