“Then I’ll take whatever weapons or armament you have here in the lab.”

“There is not very much, just the smaller items.”

“Then I’ll make my own. Are there any weapons technicians working here?”

He looked around and thought. “Old Jarl there was in the weapons sections. But there is no time to fabricate anything.”

“That’s not what I had in mind. Get him.”

Old Jarl had taken his rejuvenation treatments recently so he looked like a world-soiled nineteen-year-old with an ancient and suspicious look in his eye as he came closer.

“I want that box,” I said, pointing to the memory unit on his back. He whinnied like a prodded pony and skittered away clutching at the thing.

“Mine, I tell you mine! You can’t have it. Not fair to even ask. Without it I’ll just fade away.” Tears of senile self-pity rose to his youthful eyes.

“Control yourself, Jarl! I don’t want to fade you out; I just want a duplicate of the box. Get cracking on it.”

He shambled away, mumbling to himself, and the technicians closed in.

“I don’t understand,” Coypu said.

“Simple. If I am gunning after a large organization, I may need some heavy weapon. If I do, I’ll plug old Jarl into my brain and use his memories to build them.”

“But—he will be you, take over your body, it has never been done.”

“It’s being done now. Desperate times demand desperate measures. Which brings us to another important point. You said this would be a one-way trip through time and that I couldn’t return.”

“Yes. The time-helix hurls you into the past. There will be no helix there to return you.”

“But if one could be built there, I could return?”

“Theoretically. But it has never been tried. Much of the equipment and materials would not be available among the primitive natives.”

“But if the materials were available, a time-helix could be built. Now who do you know that could build it?”

“Only myself. The helix is of my own construction and design.”

“Great. I’ll want your memory box, too. Be sure you boys paint your names on the outside so I don’t hook up with the wrong specialist.”

The technicians grabbed for the professor.

“The time-fixator is losing power!” one of the engineers shouted in a voice filled with rising hysteria. “When the field goes down, we die. We will never have existed. It can’t be…. “He screamed this, then fell over as one of his mates gave him a faceful of knockout gas.

“Hurry!” Coypu shouted. “Take diGriz to the time-helix, prepare him!”

They grabbed me and rushed me into the next room, shouting instructions at one another. They almost dropped me when two of the technicians vanished at the same moment. Most of the voices had hysterical overtones—as well they might with the world coming to an end. Some of the more distant walls were already becoming misty and vague. Only training and experience kept me from panicking too. I finally had to push them away from the emergency space suit they were trying to jam me into in order to close the fastenings myself. Professor Coypu was the only other cool one in the whole crowd.

“Seat the helmet, but leave the faceplate open until the last minute. That’s fine. Here are the memories, I suggest the leg pocket would be the safest place. The grav-chute on your back. I assume you know how to operate it. These weapon canisters across your chest. The temporal detector here…”

There was more like this until I could hardly stand. I didn’t complain. K I didn’t take it, I wouldn’t have it. Hang on more.

“A language unit!” I shouted. “How can I speak to the natives if I don’t know their language?”

“We don’t have one here,” Coypu said, tucking a rack of gas containers under my arm. “But here is a memorygram—”

“They give me headaches.”

“—that you can use to learn the local tongue. In this pocket.”

“What do I do, you haven’t explained that yet? How do I arrive?”

“Very high. In the stratosphere, that is. Less chance of colliding with anything material. We’ll get you there. After that—you’re on your own.”

“The front lab is gone!” someone shouted, and popped out of existence at almost the same instant.

“To the time-helix!” Coypu called out hoarsely, and they dragged me through the door.

Slower and slower as the scientists and technicians vanished from sight like pricked balloons. Until there were only four of them left and, heavily burdened, I staggered along at a decrepit waddle.

“The time-helix,” Coypu said, breathlessly. “It is a bar, a column of pure force that has been warped into a helix and put under tension.”

It was green and glittered and almost filled the room, a coiled form of sparkling light as thick as my arm. It reminded me of something.

“It’s like a big spring that you have wound, up.”

“Yes, perhaps. We prefer to call it a time-helix. It has been wound up… put under tension, the force carefully calculated. You will be placed at the outer end and the restraining latch released. As you are flung into the past, the helix will hurl itself into the future where the energies will gradually dissipate. You must go.”

There were just three of us left.

“Remember me,” the short dark technician called out. “Remember Charli Nate! As long as you remember me, I’ll never… “

Coypu and I were alone, the walls going, the air darkening.

“The end! Touch it!” he called out. Was his voice weaker?

I stumbled, half fell toward the glowing end of the helix, my fingers outstretched. There was no sensation, but when I touched it, I was instantly surrounded by the same green glow, could barely sec through it. The professor was at a console, working the controls, reaching for a rather large switch.

Pulling it down…

Everything stopped.

Professor Coypu stood frozen at the controls with his hand locked on the closed switch. I had been looking in his direction, or I would not have seen this because my eyes were fixed rigidly ahead. My body as well—and my brain gave a flutter of panic and tried to bounce around in its bony pan as I realized that I had stopped breathing. For all I knew, my heart wasn’t beating either. Something had gone wrong, I was sure of that, since the time-helix was still tightly coiled. More soundless panic as Coypu grew transparent and the walls behind him took on a definitely hazy quality. It was all going, fading before my eyes. Would I be next? There was no way to know.

A primitive part of my mind, the apeman’s heir, gibbered and wailed and rushed about in little circles. Yet at the same time I felt a cold detachment and interest; it isn’t everyone who is privileged to watch the dissolving of his world while hanging from a helical force field that may possibly whip him back into the remote past. It was a privilege I would be happy to pass on to any volunteers. None presented themselves, so I hung there, popeyed and stiff as a statue while the laboratory faded away around me and I was floating in interstellar space. Apparently even the asteroid on which the Special Corps base had been built no longer had any reality in this new universe.

Something moved. I was tugged in a way that is impossible to describe and moved in a direction I never knew existed before. The time-helix was beginning to uncoil. Or perhaps it had been uncoiling all the while and the alteration in time had concealed my awareness of it. Certainly some of the stars appeared to be moving, faster and faster until they made little blurred lines. It was not a reassuring sight, and I tried to close my eyes, but the paralysis still clutched me. A star whipped by, close enough so that I could see its disk, and burned an afterimage across my retina. Everything speeded up as my time speed accelerated, and eventually space became a gray blur as even stellar events became too fast for me to see. This blur had a hypnotic effect, or my brain was affected by the time motion, because my thoughts became thoroughly muddled as I sank into a quasi-state somewhere between sleep and unconsciousness that lasted a very long time. Or a short time, I’m not really sure. It could have been an instant, or it could have been eternity. Perhaps there was some corner of my brain that remained aware of the terrible slow passage of all those years, but if so, I do not care to think about it. Survival has always been rather important to me, and as a stainless steel rat in among the concrete passages of society I look only to myself for aid. There are far more ways to fail than to succeed, to go mad than to stay sane, and I needed all my mental energies to find the right course. So I existed and stayed relatively sane during the insane temporal voyage and waited for something to happen. After an immeasurable period of time something did.
