Hull looked a little miffed. "What answer did you get?"

"A little less than eight times ten to the third kilometers per

second. I was just figuring roughly."

Hull scribbled hastily, then smiled again. "Eighteen million miles an

hour, that would be. My memory's better than I thought at first. I'm

glad I didn't have to figure the time; doing square roots is a process

I've forgotten."

That was understandable, Jayjay thought. Hull was working for his

doctorate in sociology, and there certainly wasn't much necessity for

a sociologist to remember his freshman physics, much less his

high-school math.

Still, it was somewhat of a relief to find that Hull was interested in

something besides the "sociological reactions of Man in space". The

boy had spent six months in the mining cities in the Asteroid Belt,

and another six investigating the Jovian chemical synthesis planes and

their attendant cities. Now he was heading out to spend a few more

months observing the "sociological organization Gestalt" of the men

and women who worked at the toughest job in the System--taking the

heavy metals from the particularly dense sphere of Pluto.

Hull began scribbling on his paper again, evidently lost in the joys

of elementary physics, so Jayjay Kelvin went back to his book.

He had just read three words when Hull said: "Mr. Kelvin, do you mind

if I ask a question?"

Jayjay looked up from his book and saw that Jeffry Hull had reverted

to his role of the earnest young sociologist. Ah, well. "As I've told

you before, Mr. Hull, questions do not offend me, but I can't

guarantee that the answers won't offend you."

"Yes; of course," Hull said in his best investigatory manner. "I

appreciate that. It's just that ... well, I have trained myself to

notice small things. The little details that are sometimes so

important in sociological investigations. Not, you understand, as an

attempt to pry into the private life of the individual, but to round

out the overall picture."

Jayjay nodded politely. To his quixotic and pixie-like mind, the term

_overall picture_ conjured up the vision of a large and carefully

detailed painting of a pair of dirty overalls, but he kept the smile

off his face and merely said: "I understand."

"Well, I've noticed that you're quite an avid reader. That isn't

unusual in a successful businessman, of course; one doesn't become a

successful businessman unless one has a thirst for knowledge."

"Hm-m-m," said Jayjay.

"But," Hull continued earnestly, "I noticed that you've read most of

the ... uh ... historical romances in the library...."

"You mean Westerns," Jayjay corrected quietly.

"Uh ... yes. But you don't seem to be interested in the modern

adventure fiction. May I ask why?"

"Sure." Jayjay found himself becoming irrationally irritated with

Hull. He knew that the young sociologist had nothing to do with his

own irritation, so he kept the remarks as impersonal as possible. "In

the first place, you, as a sociologist, should know what market most

fiction is written for."

"Why ... uh ... for people who want to relax and--"

"Yes," Jayjay cut in. "But what kind? The boys on Pluto? The asteroid

slicers? No. There are four billion people on Earth and less than five

million in space. The market is Earth.

"Also, most writers have never been any farther off the surface of

Earth than the few miles up that an intercontinental cruiser takes

them.

"And yet, the modern 'adventure' novel invariably takes place in

space.

"I can read Westerns because I neither know nor care what the Old

American West was _really_ like. I can sit back and sink into the

never-never land that the Western tells about and enjoy myself because

I am not forced to compare it with reality.

"But a 'space novel' written by an Earthside hugger is almost as much

a never-never land, and I have to keep comparing it with what is

actually going on around me. And it irritates me."

"But, aren't some of them pretty well researched?" Hull asked.

"Obviously, you haven't read many of them," Jayjay said. "Sure, some

of them are well researched. Say one half of one per cent, to be

liberal. The rest don't know what they're talking about!"

"But--"

"For instance," Jayjay continued heatedly, "you take a look at every

blasted one of them that has anything to do with a spacecraft having

trouble. They have to have an accident in space in order to disable

the spaceship so that the hairy-chested hero can show what a great guy

he is. So what does the writer do? He has the ship hit by a meteor! A

meteor!"

Hull thought that over for a second. "Well," he said tentatively, "a

ship _could_ get hit by a meteor, couldn't it?"

Jayjay closed his eyes in exasperation. "Of course it could! And an

air-ship can run into a ruby-throated hummingbird, too. But how often

does it happen?

"Look: We're hitting it up at about one-fortieth of the velocity of

light right now. What do you think would happen if we got hit by a

meteor? We'd be gone before we knew what had happened.

"Why doesn't it happen? Because we can spot any meteor big enough to

hurt us long before it contacts us, and we can dodge it or blast it

out of the way, depending on the size.

"You've seen the outer hull of this ship. It's an inch thick shell of

plastic, supported a hundred feet away from the steel hull by long

booms. Anything small enough to get by the detectors will be small

enough to burn itself out on that hull before it reaches the ship.

The--"

* * * * *

Jayjay Kelvin was not ordinarily a man to make long speeches,

especially when he knew he was telling someone something that they

already knew. But this time, he was beating one of his favorite drums,

and he went on with his tirade in a fine flush of fury.

Alas ... poor Jayjay.

Actually, Jayjay Kelvin can't be blamed for his attitude. All he was

saying was that it was highly improbable that a spaceship would be hit

by a meteor. In one way, he was perfectly right, and, in another, he

was dead wrong.

How small must a piece of matter be before it is no longer a meteor?

Fortunately, the big hunks rarely travel at more than about two times

ten to the sixth centimeters per second, relative to Sol, in the Solar

System. But there are little meteors--_very_ tiny ones--that come in,

hell-bent-for-leather, at a shade less than the velocity of light.

They're called cosmic rays, but they're not radiation in the strict

sense of the word. A stripped hydrogen atom, weighing on the order of

three point three times ten to the minus twenty-second grams, rest

mass, can come galumping along at a velocity so close to that of light

that the kinetic energy is something colossal for so small a particle.

Protons with a kinetic energy of ten to the nineteenth electron volts,

while statistically rare, are not unusual.

Now, ten million million million electron volts may be a wee bit

meaningless to the average man, so let's look at it from another

angle.

Consider. According to the well-known formula E = mc^2, a single gram

of matter, if converted _completely_ into energy, would yield some

nine hundred million million million ergs of energy. An atomic bomb

yields only a fraction of that energy, since only a small percentage

of the mass is converted into energy.

If _all_ of the mass of an atomic bomb were converted into energy, the

test in Alamogordo, New Mexico, 'way back in 1945, would probably have

been the last such test on Earth; there wouldn't have been anyone

around to make a second test.

So what does this have to do with cosmic ray particle? Well, if that

atomic bomb had been moving at the velocity with which our

ten-to-the-nineteenth-electron-volts proton is moving, it could have

been made of sand instead of U^235. It would have produced ten

thousand million times as much energy as the total disintegration of

the rest mass would have produced!

Kinetic energy, my children, has a great deal more potential than

atomic energy.

But we digress.

What has all this to do with Jayjay Kelvin?

If Jayjay had been a detective story addict instead of a Western story

addict, he would have heard of the HIBK or "Had I But Known" school of

detective writing. You know: "Had I But Known that, at that moment, in

the dismal depths of a secret underground meeting place, the evil

Chuman-Fu was plotting...."

If Jayjay Kelvin had known what was going on a few million miles away

from the Pluto-bound _Persephone_, he would have kept his mouth shut.

* * * * *

The cargo-ship _Mordred_ was carrying a cargo of heavy metals sunward.

In her hold were tightly-packed ingots of osmium-iridium-platinum

alloy, gold-copper-silver-mercury alloy, and small percentages of

other of the heavy metals. The cargo was to be taken to the Asteroid

Belt for purification and then shipped Earthward for final

disposition. The fact that silver had replaced copper for electrical

purposes on Earth was due to the heavy-metals industry on Pluto.

Because of Pluto, the American silver bloc had been broken at last.

The _Mordred_ was approaching turnover.

Now, with a gravito-inertial drive, there is really no need to turn a

ship over end-for-end as she approaches the mid-point of her

trajectory. Since there is no rocket jet to worry about, all that is

really necessary is to put the engine in reverse. In fact, the patrol

ships of the Interplanetary Police do just that.

But the IP has been trained to take up to five standard gees in an

end-to-end flip, and the ships are built to take the stress in both

directions. An ordinary cargo ship finds it a lot easier to simply

flip the ship over; that way, the stresses remain the same, and the

ceiling-floor relationship is constant.

The _Mordred_ had been having a little trouble with her Number Three

drive engine, so the drive was cut off at turnover, while the engineer

replaced a worn bearing. At the same time, the maintenance officer

decided he'd take a look at the meteor-bumper--the plastic outer hull.

Since the ship was in free fall, all he had to do was pull himself

along one of the beams that supported the meteor-bumper away from the

main hull. The end of one of the beams had cracked a part of the

bumper hull--fatigue from stress, nothing more, but the hull might as

well be patched while the drive was off.

It was a one-man job; the plastic was dense, but under null-gee

conditions it was easy to maneuver. The maintenance officer repaired

the slight crack easily, wiped the sticky pre-polymer from the fingers

of his spacesuit gloves, and tossed the gooey rag off into space. Then

he pushed himself back across the vacuum that separated the outer hull

from the inner, entered the air lock, and reported that the job was

finished. Five minutes later, the _Mordred_ began decelerating toward

the distant Asteroid Belt.

Forget the _Mordred_. The ship is no longer important. Keep your eyes

on that rag. It's a flimsy thing, composed of absorbent plastic and

gooed up with a little unpolymerized resin, weighing about fifty

grams. It is apparently floating harmlessly in space, just beyond the

orbit of Uranus, looking as innocuous as a rag can look. But it is

moving sunward at eight hundred million centimeters per second.

* * * * *

The _Persephone_ was approaching turnover. The ship's engineer

reported that the engines were humming along smoothly, so there was no

need to shut them off; the ship would simply flip over as she ran,

making her path a slightly skewed, elongated S-curve--a sort of

orbital hiccup.

[Illustration]

Except that she never quite made it through the hiccup. The ship was

almost perpendicular to her line of flight when she was sideswiped.

Her meteor detectors hadn't failed; they were still functioning

perfectly. But meteor detectors are built to look for solid chunks of

metal and rock--not thin, porous bits of cloth.

The rag had traveled a good many millions of miles since it had been

cast overboard; it was moving sunward with almost the same velocity

with which the _Persephone_ was moving Plutowards. The combined

velocities were such that, if it had hit the _Persephone_ dead on, it

would have delivered close to seventeen thousand kilowatt-hours of

energy in one grand burst of incandescence.

Fortunately, the tip of the rag merely gave the ship a slap on the

tail as it passed. The plastic meteor-bumper wasn't built to take that

sort of thing. The plastic became an expanding cloud of furiously

incandescent gas in a small fraction of a second, but the velocity of

that bit of rag was so great that the gas acted as a solid block of

superheated fury as it leaped across the hundred feet of vacuum which

separated the bumper hull from the inner hull.

A rocket-driven missile carrying a shaped-charge warhead weighing

several hundred pounds might have done almost as much damage.

* * * * *

Jayjay Kelvin moved his arms to pick himself up off the floor and

found that there was no necessity for doing so. He was floating in the

air of the lounge, and, strictly speaking, there was no floor anyway.

He opened his eyes and saw that that which had been the floor was now

just another wall, except that it had chairs bolted to it. It rose on

his left, reached the zenith, and set on his right, to be replaced by

another wall, and then by what had been the ceiling. The second time

the floor came round, Jayjay began to wonder whether he was spinning

around his longitudinal axis or whether the ship was actually rotating

about him. He closed his eyes again.

He didn't feel more than a little dizzy, but he couldn't be sure

whether the dizziness was caused by his spinning or the blow on his

head. He opened his eyes again and grabbed at the book that was

orbiting nearby, then hurled it as hard as he could toward the

sometime ceiling. "The Pride of the Pecos" zoomed rapidly in one

direction while Jayjay moved sedately in the other.

The ship was spinning slightly, all right. When he finally grabbed a

chair, he found that there was enough spin to give him a weight of an

ounce or two. He sat down as best he could and took a good look

around.

Aside from "The Pride of the Pecos" and a couple of other books, the

air was remarkably free from clutter. There hadn't been much loose

stuff laying around. A pencil, a few sheets of paper--nothing more.

There was one object missing. Jayjay looked around more carefully, and

this time he saw a hand protruding from the space "beneath" the low

table. He bent down for a better look and saw that Jeffry Hull was

unconscious. Blood from his nose was spreading slowly over his face,

and one eye looked rather battered. Jayjay grasped the protruding

wrist and felt for a pulse. It was pumping nicely. He decided that

Hull was in no immediate danger; very few people die of a bloody nose.

The lighting in the lounge was none too good; the low-power emergency

system had come on automatically when the power from the ship's

engines had died. Jayjay wondered just what had happened. There had

been a hell of an explosion; that was all he knew.

He wondered if anyone else aboard was alive and conscious, and decided

he might as well find out. He took a long dive toward the central

stairwell that ran the length of the ship's long axis and looked down.

The emergency door to the cargo hold was closed. No air, most likely.

The way up looked clear, so he scrambled up the spiral stairway.

A few feet farther up, he found that he had passed the center of the

ship's rotation. The _Persephone_ was evidently toppling end-over-end,

and the center of rotation was in the lounge itself. The heavy cargo in

the hold was balancing the lighter, but longer, part of the ship above the

lounge. He began climbing down the stairwell toward the navigation and

control sections.

Somewhere down there, somebody was cursing fluently in Arabic.

"Illegitimate offspring of a mangy she-camel! Eater of dogs! Wallower

in carrion!" And then, with hardly a break: "Allah, All-Merciful,

All-Compassionate! Have mercy on Thy servant! I swear by the beard of

Thy holy Prophet that I will attend more closely to my duties to Thee

if Thou wilt get me loose from this ill-begotten monstrosity! Help me

or I perish!" The last words were a wail.

"I'm coming!" boomed Jayjay in the same tongue. "Save thy strength!"

* * * * *

There was silence from the control room as Jayjay clambered on down

the stairwell. Fortunately, the steps had been built so that it was

possible to use them from either side, no matter which way the gravity

pull happened to be. By the time he reached the control room, he

weighed a good fifteen pounds.

Captain Atef al-Amin was staring up at the stairs as Jayjay came down.

He was jammed tightly into a space between two of the big control

cabinets, hanging head downward and looking more disheveled than

Jayjay had ever seen the usually immaculately-uniformed captain.

"Oh," said Captain Al-Amin, in English, "it's you. For a moment I

thought--" Then he waved his free hand. "Never mind. Can you get me

out of here?"

What had been the floor of the control room was now the ceiling. The

two steel cabinets which housed parts of the computer unit now

appeared to be bolted to the ceiling. They were only about five feet

high, and the space between them was far too narrow for a man to have

got in there by himself--especially a man of the captain's build. None

the less, he was in there--jammed in up to his waist. Only his upper

torso and one arm was free. The other arm was jammed in against the

wall.

Jayjay took the leap from the stairs and grabbed on to the chair that

hung from the ceiling nearby. When you only weigh fifteen pounds, you

can make Tarzan look like an amateur.

"You hurt?" he asked.

"It isn't comfortable, sure as hell," said Al-Amin. "I think my arm's

broken. Think you can get me loose?"

"I can try. Give me your hand." Jayjay took the captain's free hand

and gave it a tug. Then he released the chair he was holding, braced

both feet against the panels of the computer housings, and gave a good

pull. The captain didn't budge, but he winced a little.

"That hurt?"

"Just my arm. The pressure has cut off my blood circulation; my legs

are numb, and I can't tell if they hurt or not."

Jayjay grabbed the chair again and surveyed the situation. "Where's

your First Officer?"

"Breckner? Down in the engine room."

Jayjay didn't comment on that. If the hold was airless, it was likely

that the engine room was, too, and there was no need to worry Al-Amin

any more than necessary just now.

"Can you use a cutting torch?" the captain asked.

"Yes, but I don't think it'll be necessary," Jayjay said. "Hold on a

minute." He went back up the stairs to the officers' washroom and,

after a little search, got a container of liquid soap from the

supplies. Then he went back down to the control room. He made the jump

to the chair, holding on with one hand while he held the container of

soap with the other.

"Can you hold me up with one hand? I'll need both hands to work with."

"In this gravity? Easy. Give me your belt."

Captain Atef Al-Amin grabbed Jayjay's belt and hung on, while Jayjay

used both hands to squirt the liquid soap all over the captain from

the waist down.

It would have made a great newspaper photo. Captain Al-Amin, wedged

between two steel cabinets, hanging upside-down under a pull of

one-fifteenth standard gee, holding up his rescuer by the belt. The

rescuer, right-side-up, was squeezing a plastic container of liquid

soap and directing the stream against the captain.

When Al-Amin was thoroughly wetted with the solution, Jayjay again

braced his feet against the steel panels and pulled.

With a slick, slurping sound, the captain slid loose, and the two of

them toppled head-over-heels across the room. Jayjay was prepared for

that; he stopped them both by grasping an overhead desk-top as they

went by. Then he let go, and the two men dropped slowly to what had

been the ceiling.

"_Hoo!_" said the captain. "That's a relief! Allah!"

Jayjay took a look at the man's arm. "Radius might be broken; ulna

seems O.K. We'll splint it later. Your legs are going to tingle like

crazy when the feeling comes back."

"I know. But we have other things to worry about, Mr. Kelvin.

Evidently you and I are the only ones awake so far, and I'm in no

condition to go moving all over this spinning bucket just yet. Would

you do some reconnoitering for me?"

"Sure," said Jayjay. "Just tell me what you want."

* * * * *

Within half an hour, the news was in.

There were five men alive in the ship: Jayjay, Captain Al-Amin, Jeffry

Hull, Second Officer Vandenbosch, and Maintenance Officer Smith.

Vandenbosch had broken both legs and had to be strapped into a bunk

and given a shot of narcolene.

Jayjay had put on a spacesuit and taken a look outside. The whole rear

end of the ship was gone, and with it had gone the First Officer, the

Radio Officer, and the Engineering Officer. And, of course, the main

power plant of the ship.

Most of the cargo hold was intact, but the walls had been breached,

and the air was gone.

"Well, that's that," said Captain Al-Amin. Jayjay, Smith, Hull, and

the captain were in the control room, trying not to look glum. "I wish

I knew what happened."

"Meteor," Jayjay said flatly. "The bumper hull is fused at the edges

of the break, and the direction of motion was inward."

"I don't see how it could have got by the meteor detectors," said

Smith, a lean, sad-looking man with a badly bruised face.

"I don't either," the captain said, "but it must have. If the engines

had blown, the damage would have been quite different."

Jeffry Hull nervously took a cigarette from his pocket pack. His nose

had quit bleeding, but his eye was purpling rapidly and was almost

swollen shut.

Captain Al-Amin leaned over and gently took the cigarette from Hull's

fingers. "No smoking, I'm afraid. We'll have to conserve oxygen."

"You guys are so damn _calm_!" Hull said. His voice betrayed a surface

of anger covering a substratum of fear. "Here we are, heading away

from the Solar System at eighteen million miles an hour, and you all

act as if we were going on a picnic or something."

The observation was hardly accurate. Any group of men who went on a

picnic in the frame of mind that Jayjay and the others were in would

have produced the gloomiest outing since the Noah family took a trip

in an excursion boat.

"There's nothing to worry about," Captain Al-Amin said gently. "All we

have to do is set the screamers going, and the Interplanetary Police

will pick us up."

"Screamers?" Hull looked puzzled.

Instead of answering the implied question, the captain looked at

Smith. "Have you checked them?" He knew that Smith had, but he was

trying to quiet Hull's fears.

Smith nodded. "They're O.K." He looked at Hull. "A screamer is an

emergency radio. There's one in every compartment. You've seen them."

He pointed across the room, toward a red panel in the wall. "In

there."

"But I thought it was impossible for a spaceship in flight to contact

a planet by radio," Hull objected.

"Normally, it is," Smith admitted. "It takes too much power and too

tight a beam to get much intelligence over a distance that great from

a moving ship. But the screamers are set up for emergency purposes.

They're like flares, except that they operate on microwave frequencies

instead of visible light.

"The big radio telescopes on Luna and on the Jovian satellites can

pick them up if we beam them sunward, and the Plutonian station can

pick us up if we beam in that direction."

Hull looked much calmer. "But where do you get the power if the

engines are gone? Surely the emergency batteries won't supply that

kind of power."

"Of course not. Each screamer has its own power supply. It's a

hydrogen-oxygen fuel cell that generates a hell of a burst of power

for about thirty minutes before it burns out from the overload. It's

meant to be used only once, but it does the job."

"How do they know where to find us from a burst like that?" Hull

asked.

"Well, suppose we only had one screamer. We'd beam it toward Pluto,

since it would be easier for an IP ship to get to us from there. Since

all screamers have the same frequency--don't ask me what it is; I'm

not a radio man--the velocity of our ship will be indicated by the

Doppler Effect. That is, our motion toward or away from them can be

calculated that way. Our angular velocity with respect to them can be

checked while the screamer is going; they will know which direction

we're moving, if we're moving at an angle.

"With that information, all they have to do is find out which ship is

in that general area of the sky, which they can find out by checking

the schedule, and they can estimate approximately where we'll be. The

IP ship will come out, and when they get in the general vicinity, they

can find us with their meteor detectors. Nothing to it."

"And," Captain Al-Amin added, "since we have eight screamers still

left with us, we have plenty of reserves to call upon. There's

nothing to worry about, Mr. Hull."

"But how can you aim a beam when we're toppling end-over-end like

this?" Hull asked.

"Well, if we couldn't stop the rotation," said the captain, "we'd

broadcast instead of beaming. Anywhere within the Solar System, a

screamer can broadcast enough energy to overcome the background noise.

"The IP would have a harder time finding us, of course, but we'd be

saved eventually."

"I see," said Hull "How do we go about stopping the rotation?"

"That's the next thing on the agenda," Al-Amin said. "This seasick

roll is caused by the unevenness of the load, and I'm pretty sick of

it, myself. Smith, will you and Mr. Kelvin get out the emergency

rockets? We'll see what we can do to stabilize our platform."

* * * * *

It took better than an hour to get the ship straightened out. For the

main job, emergency rockets were set off at the appropriate spots

around the hull to counteract the rotation. The final trimming was

done with carbon dioxide fire extinguishers, which Smith and Jayjay

Kelvin used as jets.

Getting a fix on Pluto was easy enough; the lighthouse station at Styx

broadcast a strong beep sunward every ten seconds. They could also

pick up the radio lighthouses on Eros, Ceres, Luna, and Mimas.

Evidently, the one on Titan was behind the Jovian bulk.

They were ready to send their distress call.

"It's simple," Smith said as he opened the red panel in the wall of

the control room. "First we turn on the receiver." He pushed a button

marked _R_. "Then we turn these two wheels here until the pip on that

little screen is centered. That's the signal from Pluto. It comes in

strong every ten seconds, see?"

Jayjay watched with interest. He'd heard about screamers and had seen

them, but he'd never had the opportunity of observing one in action.

Like flares or bombs, they were intended for one-time use. The

instructions were printed plainly on the inside of the red door, and

Smith was simply reading off what was printed there.

"These wheels," he was saying, "line up the parabolic reflector with

the Pluto signal, you see. There. Now we've got it centered. Now, all

we have to do is make one small correction and we're all set. These

things are built so that they're fool-proof; a kid could operate it.

Watch."

Facing each other across a small gap were a pair of tapered screw

plugs, one male and one female. The male was an average of half an

inch in diameter; the female was larger and bored to fit the male.

"The female plug," Smith said, "leads to two tanks of high-pressure

gas inside this cabinet on the left. One tank of oxygen, one of

hydrogen. See how this male plug telescopes out to fit into the

female? All we have to do is thread them together, and everything is

automatic."

Jayjay was aware that Smith's explanations were meant to give Jeffry

Hull something to think about instead of his fears. Hull was basically

an Earth-hugger, and free fall did nothing to keep him calm. Evidently

his subconscious knew that he had to latch on to something to keep his

mental equilibrium, because he showed a tremendous amount of interest

in what should have been a routine operation.

"How do you mean, it's all automatic?" he asked. "What happens?"

"Well, you can't see into the female plug, but look here at the male.

See those concentric tubes leading into the interior of the cabinet on

the right? The outer one leads in the oxygen, the inner leads in the

hydrogen. We need twice as much hydrogen as oxygen, so the inner tube

has twice the volume delivery as the outer. See?"

"Yes. But what is the solid silver bar in the center of the inner

tube?"

"That's the electrical connection for the starter battery. There's a

small, short-lived chemical battery, like the ones in an ordinary

pocket radio, except that they're built to deliver a high-voltage,

high-amperage current for about a tenth of a second. That activates

the H-O cell, you see. Also, that silver stud depresses the

corresponding stud in the female plug, which turns on the gas flow

before it makes the connection with the starter battery. Follow?"

Hull didn't look as though he did, but he nodded gamely. "Then what

happens?"

"Then the hydrogen and the oxygen come together in the fuel cell and,

instead of generating heat, they generate electric current. That

current is fed into the radio unit, and the signal is sent to Pluto.

Real simple."

"I see," Hull said. "Well ... go ahead."

Smith telescoped the two leads together and began turning the collar

on the female plug.

He screwed it up as far as it would go.

And nothing happened.

"What the hell?" asked Smith of no one in particular. He tried to

twist it a little harder. Nothing happened. The threads had gone as

far as they would go.

"What's the matter?" Jayjay asked.

"Damfino. No connection. Nothing's happening. And it's as tight as it

will go."

"Are the gases flowing?" Jayjay asked.

"I don't know. These things aren't equipped with meters. They're

supposed to work automatically."
