The squawk box on the wall said, "Calling Gant Nerley with report."

"Report!"

"Report slight increase in phanoradiation high in the subnuclear

region. Cross semi-collateral traces indicating an increase in

lower-level nuclear activity."

The squawk box clicked off and Dusty looked with puzzlement at Gant

Nerley. "What was all that?" he pleaded.

"He means that Transgalactic is hard at work. The lower level of

nuclear reactions has increased in intensity, meaning in simple

prediction that the business of making a variable star out of Sol is

under way."

The Marandanian with the filar micrometer on the barytrine detector

grumbled. "It's going to be a bit rough."

"Why?" asked the pilot. "If it weren't for that barytrine we'd never

find Sol out of that mess dead ahead. We'd be canvassing the stellar

region around there for weeks if we didn't have a focal point--"

"I know," grunted the detector operator. "First you need a barytrine

field large enough to make a homing run on, but then once you're home

you'll want a tiny one so you can locate the generator precisely. Well,

you can't have 'em both, Jann."

Jann Wilkor shook his head. "I wish I'd made this run before. I could

make it faster."

Gant pointed at the screen and nudged Dusty. The color-scale was still

high in the blue-violet and there were a couple of places on the

viewpanel that were a dead black, tiny spots that did not move as Jann

Wilkor's delicate touch corrected the course. Spots burned out of the

substance of the panel like over-exposed film burned through.

"It takes a master pilot to make a run this fast. Even so, we're taking

a rather high risk. But if the channel was free and open from Marandis

to Spiral Cluster, with only a big phanobeacon at either end, we could

make it with the screen burning black-violet. We may even have to

develop a new supraradiant material for ultra-high velocities."

"How fast can you go?"

Jann Wilkor soared around a beacon and centered on the next before

the flicking wave of heat was gone. He did it easily and with the

negligent reflex of the master pilot. "Fitt Mazorn took one of the

high speed jobs into intergalactic space for a speed run a year ago

and claims to have made it from Laranonne to Ultimane in slightly less

than an hour. Or," corrected the pilot, "an equivalent distance, out in

deep-deep space. Some of this is probably guff; I doubt that he could

do it. That's a hundred thousand light-years per hour and just a bit

fantastic. Trouble is that the phanobands propagate at a finite speed,

according to Hahn Tratter, and therefore the true velocity is difficult

to check, since no one has been able to measure phanoband velocity."

"At any rate, it's fast," said Dusty, who did not understand half of

what the pilot said.

Gant nodded. "It's fast. It's what we'll be doing in your clear

channels, Dusty. That will make you rich and famous, that idea of

yours."

"Iffing and providing we can get there in time."

"No matter. If Terra is lost to you, you'll still--"

"Look," said Dusty, "if that bunch wins out, I'll--"

"And I won't blame you," replied Gant.

There came a double report. The man on the barytrine detector said,

"Barytrine field just went into the second phase," at the same time

that the pilot said, "Last lap!" and turned his point of aim around the

beacon to center the hairs on a small star that did not wink.

"Our next problem is to scour Terra inch by inch to find their

barytrine generator," said Gant worriedly.

Dusty groaned. He thought of the trackless wastes of the planet; the

Upper Amazon jungles, the tundra of Alaska and Siberia, the hidden

reaches of Africa, high Tibet, and for that matter the cornfields of

Iowa and the wheat fields of Saskatchewan. The fathomless, staggering

area of the sea bottoms was too vast a hopeless search-problem to

contemplate.

* * * * *

Gant looked at Dusty. "It's bad, Dusty. I'll not fool you, but it's

bad. We have perhaps a day or two, perhaps three. We're late. By the

time we arrive, the phase-two growth will be heavy enough to cause

leakage-reaction in our detector and render the detector completely

ambiguous."

"Meaning what?"

"What I said. That we must scour Terra inch by inch. And here is where

you must help."

"Me?"

"Yes. You must issue orders to your Space Patrol to comb the landscape.

You must find that barytrine generator."

Dusty looked at Gant Nerley blankly. "You realize what you're asking?

That within a matter of hours we must set up a land-scouring search

and completely cover the entire earth? I haven't even got the foggiest

notion of how many million square miles of earth there are, let alone

the ocean-bottom which we couldn't even touch, lacking the equipment."

"They wouldn't plant it on a sea bottom."

"No? Look, Gant, remember that they're planning on keeping this thing

running for a thousand years. They'll have to hide it good."

Gant shook his head with a wan smile. "Not at all. You forget that so

far as anybody within the barytrine field is likely to see it, the

total time will be from right now until the field goes on in a few

hours. Then the enclosure-time will elapse instantaneously for those

within. Anybody who finds it once the job goes on will find it after

you have been freed of the field. The chances are high that they've

dropped it in some comfortable climate, possibly near a large city,

just as Scyth Radnor did."

Dusty eyed Gant sourly. "For the same purpose?" he asked.

"Probably. After all, Dusty--" Gant let the statement hang, suggesting

silently that Dusty was the kind of human who would think of the same

thing and act on it. "So you must issue orders to your Patrol--"

Dusty grunted. His Patrol? Discredited, his position shot to bits, his

public appeal running somewhere near absolute zero, who would even

listen to him? His former admirers had shucked their Space Patrol

clothing for the costume of Jack Vandal, Space Rover.

Then he sat up with a puzzled smile.

"You have an idea?"

"I hope so."

"And--?"

Dusty smiled wistfully. "From the time Scyth Radnor opened his

spacelock and blasted off the end of my antenna, I've been running a

losing battle," he said. "I've been playing a game far over my head;

outpointed, overbid, overdrawn and sinking. About the only reason I'm

still here fighting is that some of the rules of this cockeyed game

seem to fall into my own act. Yes, dammit, I've got an idea. Can I call

the orders, Gant?"

"Take over, Dusty."

Dusty turned to the pilot. "When we get there," he said, "Circle the

planet several times as fast and as low as you can. Create a stir.

Radiate like mad, anything you can radiate. Call attention to us in a

bold fashion and show 'em that what we've got is big, important and

powerful." Then to Gant Nerley he put the question, "You wouldn't have

anything as primitive as a radio set aboard, would you?"

"You mean a radiomagnetic communication device? Well, not for

communications but we do have a small receiver for detecting the

lower-radiation stars and one for scanning planetary systems for

primitive cultures. What did you have in mind?"
