He grinned sourly. "Next time you'll pay attention to the signal."

There were worse times and places to argue about it, but Alsint

couldn't remember them. "There wasn't any signal," he said. He caught

the cynical expression on the guard's face and extended his hand. "See

for yourself."

The watch was working, indicating time till takeoff, but the

unmistakable glow and the irritating tingle, guaranteed to wake any man

out of a sleep this side of the final one, were missing.

The guard blinked. "Never heard of that ever happening," he said. "Tell

you what--I'll testify that it wasn't your fault. That'll clear you.

You can get a job on the next ship and catch up with your own in a

month at the most."

It wasn't that easy, nor so simple. Alsint glanced frantically at the

watch. Minutes left now, though he couldn't be sure. If the signal

wasn't functioning, maybe the time was wrong too. "I'll never get on

that one again," he said. "It's a tag ship."

The guard scrutinized him more closely, differentiating his uniform

from others similar to it. "In that case you'd better go to the traffic

tower," he said reluctantly. "They'll stop it for you."

They would, but he'd waste half an hour getting past the red tape at

the entrance. There were a number of reasons why he couldn't let the

ship leave without him. "I know our crew," he said. "They'll be waiting

for me. Let me try to get on."

The guard shrugged. "It's your funeral." Slowly the gate swung open.

Alsint dashed through. He had to hurry, but it wasn't as dangerous as

the guard imagined. The watch had failed, but inside the ship was a

panel which indicated the presence or absence of any crew member. That

panel was near the pilot. He wouldn't take off without clearing it.

Besides, there was standard takeoff procedure--always someone at the

visionport, watching for latecomers, of which there were usually a

few. Alsint raised his head as he ran. He couldn't see anyone at the

visionport.

Breathing heavily, he brushed against the ship. Late, but not too late.

He turned the corner at the vane.

He didn't like what he saw. The ramp was up and the outer lock was

closed. They were waiting for clearance from the spaceport.

His composure slipped a little. If the clearance came within the next

few minutes, he'd be dead. Not that the clearance would come. A ship

just didn't lift off, leaving one of the crew behind--or he hoped it

didn't.

He pounded on the lock and shouted, though it was useless. Inside, they

couldn't hear him. The noise frightened a little red bird which had

been hovering nearby. It flew around his head, squawking shrilly.

* * * * *

Alsint scowled at it. It reminded him unpleasantly of the park. If he

hadn't gone there, he'd be safe inside the ship. True, parks were rare,

and people who went to them even more rare. After so many months in the

ship, it had been a great temptation--for him, not the others. No one

else had been interested.

Now he had to get in. A tremor ran through the hull and he realized how

urgent it was. A little more of this and he would be caught under the

rockets.

The airlock was smooth, but he located the approximate latching point

on the outside and stripped off the watch, holding it against the ship

by the band. He tried to remember and thought the face should be turned

inward. He held it that way and hoped he was right. He closed his eyes

and swung hard with his fist.

His hand exploded with pain and he could feel the flash on his face.

The energy, which was sufficient to drive the instrument for a thousand

years, dissipated in much less than a second. An instant later the hand

which held the strap reacted to the heat. He dropped the useless watch

and opened his eyes.

He had figured it right and he was also lucky. The energy had turned

inward, as he had hoped, otherwise he'd have no hand, and the latching

mechanism had been destroyed. The resulting heat had buckled the plate

outward. The hull was trembling with greater violence as the takeoff

rockets warmed up.

The airlock was still very hot. His fingers sizzled as he grasped the

curled edge and pulled out. It moved a little. He shifted his hands for

a better grip and heaved. It opened.

He scrambled inside and shut it behind him, latching it with the

emergency device. Close, but it didn't matter as long as he'd made it.

The ship began to rise and the acceleration forced him to kneel in the

passageway between the outer and inner lock. He kept thinking of the

little red bird he'd seen outside. Burned, no doubt, as he would have

been.

Finally the rockets stopped and the heaviness disappeared. They were

out of the atmosphere and hence the ship had shifted to interstellar

drive. The heat from the rockets began to abate. He was grateful for

that.

He got to his feet and staggered to the inner lock and leaned against

it. That didn't open, either. He shouted. It might take time, but

eventually someone would come close enough to hear him.

There was air in the passageway and he knew he could survive. It had

been too hot; now it was getting cold. He shivered and shook his head

in bewilderment.

None of this was the way it ought to be. It had never been difficult to

get on the ship. If he didn't know better, he'd say--

But this was not the time to say that.

He didn't hear the footsteps on the other side. The lock swung in and

he fell forward. His burned hands were too cold to hurt as he checked

his fall.

Scantily clad, Larienne stood over him. "Playing hiding games?" she

asked. She got a better look and knelt by his side. "You're hurt!"

So he was, but mostly he was tired. In the interval before he accepted

the luxury of unconsciousness, the thought flashed across his mind

before he could disown it: Someone on the ship was trying to take the

plant away, or wanted him to fail.

Either would have been accomplished if he had been left behind.

* * * * *

He sat in his room, thinking. He wished he knew more about the crew.

Six months was enough to give him wide acquaintance, but not the deep

kind. They were a clannish lot on the ship. His own assistant he knew

well enough, and the doctor. The captain he hardly ever saw. The rest

of them he knew by sight and name, but not much else: the few married

couples, the legally unattached girls, and the larger number of male

technicians.

None of them, as far as he could see, had any incentive to engineer the

mixup which had nearly caused him to miss the ship. Of course he might

be reading into it more than was there. It could have happened that way

accidentally. And then maybe it didn't.

His thoughts were interrupted by a knock. "Who's there?" he called.

Larienne walked in. "Nobody asks _who_," she said. "It's always _come

in_. Even I know that, and I've been on this traveling isolation ward

a mere three years."

She dropped into a chair and draped her legs, long legs that were worth

showing off. She had a certain air of impartiality that attracted

attention. She was smart, though, and knew when to discard impartiality.

She eyed him curiously. "I'm trying to discover the secret of your

popularity. That damn plant is pining for you."

"It's not me," he said. "You have to know how to handle it."

"Thanks," she said dryly. "I don't know how. But Richel Alsint, boy

plant psychologist, does. He knows when to increase the circulation,

when to give it an extra shot of minerals, and when, on the other hand,

to scare the damn thing out of its wits, which I sometimes believe it

actually has."

"Don't personalize it," he warned. "It's partly plant and partly a

machine. Your mistake is that you treat it as if it were wholly a

machine."

"Seems to me I've heard that before. What should I do that I don't?"

"Cycles," he said. "Rhythm. A machine doesn't need that kind of

treatment, but a plant does. Normally it starts as a seed, grows to

maturity, produces more seeds, and eventually dies. Our plant isn't

like that, of course. It never produces seeds, and, if we're careful,

doesn't die. Yet it does have something that faintly corresponds to

the original cycles."

She sighed. "It might help if I knew what it was--geranium, or

sunflower, or whatever."

He had told her, but apparently she didn't want to remember. "It isn't

one plant. It's been made from hundreds; even I don't know what they

were. One best feature from this, another strong feature from something

else. We've taken plants apart and recombined them into something new.

This is just--plant."

* * * * *

Larienne dropped her legs to a more comfortable if less esthetic

position. "Hydroponics was simpler," she objected.

"It was," he said. "And if you want to know, old-fashioned dirt farming

was even simpler. Our combination plant and machine is merely a step

and a half ahead of hydroponics."

"Suppose you come out and tell me what I've done wrong," she said,

getting up.

"One last thing," he said. "Remember that plants evolved on planets.

No matter what we do, we can't convince the plant that it's still

on a planet. Light's the easiest. As far as we know, it will grow

indefinitely under our artificial light. Artificial gravity is

different. I don't know the difference, and neither do the physicists,

but the plant does. It can live in the ship just so long and then has

to be taken out for a rest. There are other things that affect it,

vibration, noise, and maybe more. You know how I have to keep after the

pilot to dampen his drive. All these things change the cycle it has to

have."

"Agreed," she said impatiently, meaning mostly that she didn't care.

"Let's go out and look at it."

The plant was a machine and the machine was a plant. It occupied

a large space in the center of the ship. And it wasn't wasted

space; properly cared for, the plant could supply food for the crew

indefinitely.

The plant machine evolved from earlier attempts to convert raw material

and energy into food. Originally algae were used because they were

hardy and simple to control. But the end product had to be processed

and algae did not produce the full scale of nutrients in the proper

proportion for the human diet.

Certain cells of more highly evolved plants were far more efficient in

the conversion of raw materials into proteins, vitamins and the like.

Originally, inedible parts were produced too, the stalk, which might or

might not be used for food, and the leaves and roots. On a planet with

plenty of room, this made little difference. But on an overcrowded

planet, or one with a poisonous atmosphere, and especially on a ship

where space was at a premium, normal methods could not be used.

In the plant machine were certain cells which had been selected because

of their ability to produce a variety of nutrients. The inedible parts

of the plant were replaced by machinery. Instead of roots to draw water

and minerals from the soil, there were pumps and filters. Instead of

stems to elevate that material to the leaves, there were hoses. Instead

of entire leaves to perform photosynthesis, there were only those cells

most efficient at the process. There were no seeds, tubers, roots, nor

fleshy stalks to store the food. Collecting trays replaced them. There

was no waste space; nothing was produced that couldn't be eaten.

There was an additional problem of reconciling the various cell fluids

and different rates of growth. In part, that was accomplished by the

plant machinery; the rest depended on the plant mechanic. His job was

akin to that of a factory manager. In a sense, the plant machine was

nothing more than a highly organized and complex factory, of which the

productive units were the actual cells.

Alsint went along the aisles. Dials and gauges everywhere--a continuous

record was kept of every stage. Each record was important, but nothing

that could be reduced to a formula. The plant was not in bad shape,

considering. At his instructions, Larienne made certain adjustments.

"Why reduce the light?" she asked. "I thought this unit grew better

with stronger light."

"It does, within limits."

"I was within those limits."

"You were, but consider this. The plant from which these cells came

grow fastest in early summer, but it isn't edible at that time. In

late summer, it is. The light change merely corresponds to original

conditions."
