They went back to work on the jets with a furious energy that received
impetus every half hour when the Shadow rose again over the horizon, bigger
and more menacing than before.
Long had no assurance that it would work. Even if the jets would respond
to the distant controls, even if the supply of water, which depended upon a
storage chamber opening directly into the icy body of the planetoid, with
built-in heat projectors steaming the propulsive fluid directly into the
driving cells, were adequate, there was still no certainty that the body of
the planetoid without a magnetic cable sheathing would hold together under the
enormously disruptive stresses.
"Ready!" came the signal in Long's receiver.
Long called, "Ready!" and depressed the contact.
The vibration grew about him. The star field in the visiplate trembled.
In the rearview, there was a distant gleaming spume of swiftly moving
ice crystals.
"It's blowing!" was the cry. It kept on blowing. Long dared not stop.
For six hours, it blew, hissing, bubbling, steaming into space; the body of
the planetoid converted to vapor and hurled away.
The Shadow came closer until men did nothing but stare at the mountain
in the sky, surpassing Saturn itself in spectacularity. Its every groove and
valley was a plain scar upon its face. But when it passed through the
planetoid's orbit, it crossed more than half a mile behind its then position.
The steam jet ceased.
Long bent in his seat and covered his eyes. He hadn't eaten in two days.
He could eat now, though. Not another planetoid was close enough to interrupt
them, even if it began an approach that very moment.
Back on the planetoid's surface, Swenson said, " All the time I watched
that damned rock coming down, I kept saying to myself, 'This can't happen. We
can't let it happen.'"
"Hell," said Rioz, "we were all nervous. Did you see Jim Davis? He was
green. I was a little jumpy myself."
"That's not it. It wasn't just--dying, you know. I was thinking--I know
it's funny, but I can't help it--I was thinking that Dora warned me I'd get
myself killed, she'll never let me hear the last of it. Isn't that a crummy
sort of attitude at a time like that?"
"Listen," said Rioz, "you wanted to get married, so you got married. Why
come to me with your troubles?"

The flotilla, welded into a single unit, was returning over its mighty
course from Saturn to Mars. Each day it flashed over a length of space it had
taken nine days outward.
Ted Long had put the entire crew on emergency. With twenty-five ships
embedded in the planetoid taken out of Saturn's rings and unable to move or
maneuver independently, the coordination of their power sources into unified
blasts was a ticklish problem. The jarring that took place on the first day of
travel nearly shook them out from under their hair.
That, at least, smoothed itself out as the velocity raced upward under
the steady thrust from behind. They passed the
one-hundred-thousand-mile-an-hour mark late on the second day, and climbed
steadily toward the million-mile mark and beyond.
Long's ship, which formed the needle point of the frozen fleet, was the
only one which possessed a five-way view of space. It was an uncomfortable
position under the circumstances. Long found himself watching tensely,
imagining somehow that the stars would slowly begin to slip backward, to whizz
past them, under the influence of the multi-ship's tremendous rate of travel.
They didn't, of course. They remained nailed to the black backdrop,
their distance scorning with patient immobility any speed mere man could
achieve.
The men complained bitterly after the first few days. It was not only
that they were deprived of the space-float. They were burdened by much more
than the ordinary pseudo-gravity field of the ships, by the effects of the
fierce acceleration under which they were living. Long himself was weary to
death of the relentless pressure against hydraulic cushions.
They took to shutting off the jet thrusts one hour out of every four and
Long fretted.
It had been just over a year that he had last seen Mars shrinking in an
observation window from this ship, which had then been an independent entity.
What had happened since then? Was the colony still there?
In something like a growing panic, Long sent out radio pulses toward
Mars daily, with the combined power of twenty-five ships behind it. There was
no answer. He expected none. Mars and Saturn were on opposite sides of the Sun
now, and until he mounted high enough above the ecliptic to get the Sun well
beyond the line connecting himself and Mars, solar interference would prevent
any signal from getting through.
High above the outer rim of the Asteroid Belt, they reached maximum
velocity. With short spurts of power from first one side jet, then another,
the huge vessel reversed itself. The composite jet in the rear began its
mighty roaring once again, but now the result was deceleration.
They passed a hundred million miles over the Sun, curving down to
intersect the orbit of Mars.
A week out of Mars, answering signals were heard for the first time,
fragmentary, ether-torn, and incomprehensible, but they were coming from Mars.
Earth and Venus were at angles sufficiently different to leave no doubt of
that.
Long relaxed. There were still humans on Mars, at any rate.
Two days out of Mars, the signal was strong and clear and Sankov was at
the other end.
Sankov said, "Hello, son. It's three in the morning here. Seems like
people have no consideration for an old man. Dragged me right out of bed."
"I'm sorry, sir."
"Don't be. They were following orders. I'm afraid to ask, son. Anyone
hurt? Maybe dead?"
"No deaths, sir. Not one."
"And--and the water? Any left?"
Long said with an effort at nonchalance, "Enough."
"In that case, get home as fast as you can. Don't take any chances, of
course."
"There's trouble, then."
"Fair to middling. When will you come down?"
"Two days. Can you hold out that long?"
"I'll hold out."
Forty hours later Mars had grown to a ruddy-orange ball that filled the
ports and they were in the final planet-landing spiral.
"Slowly," Long said to himself, "slowly." Under these conditions, even
the thin atmosphere of Mars could do dreadful damage if they moved through it
too quickly.
Since they came in from well above the ecliptic, their spiral passed
from north to south. A polar cap shot whitely below them, then the much
smaller one of the summer hemisphere, the large one again, the small one, at
longer and longer intervals. The planet approached closer, the landscape began
to show features.
"Prepare for landing!" called Long.

Sankov did his best to look placid, which was difficult considering how
closely the boys had shaved their return. But it had worked out well enough.
Until a few days before, he had no sure knowledge that they had
survived. It seemed more likely--inevitable, almost--that they were nothing
but frozen corpses somewhere in the trackless stretches from Mars to Saturn,
new planetoids that had once been alive.
The Committee had been dickering with him for weeks before the news had
come. They had insisted on his signature to the paper for the sake of
appearances. It would look like an agreement, voluntarily and mutually arrived
at. But Sankov knew well that, given complete obstinacy on his part, they
would act unilaterally and be damned with appearances. It seemed fairly
certain that Hilder's election was secure now and they would take the chance
of arousing a reaction of sympathy for Mars.
So he dragged out the negotiations, dangling before them always the
possibility of surrender.
And then he heard from Long and concluded the deal quickly.
The papers had lain before him and he had made a last statement for the
benefit of the reporters who were present.
He said, "Total imports of water from Earth are twenty million tons a
year. This is declining as we develop our own piping system. If I sign this
