He had covered disasters before, but this time he felt uncommonly like a ghoul.
It was very peaceful now, aboard Selene so peaceful that one had to fight against sleep. How pleasant it would be, thought Pat, if he could join the others, dreaming happily all around him. He envied them, and sometimes felt jealous of them. Then he would take a few draughts from the dwindling store of oxygen, and reality would close in upon him as he recognized his peril.
A single man could never have remained awake, or kept an eye on twenty unconscious men and women, feeding them oxygen whenever they showed signs of respiratory distress. He and McKenzie had acted as mutual watchdogs; several times each had dragged the other back from the verge of sleep. There would have been no difficulty had there been plenty of oxygen, but that one bottle was becoming rapidly exhausted. It was maddening to know that there were still many kilograms of liquid oxygen in the cruiser's main tanks, but there was no way in which they could use it. The automatic system was metering it through the evaporators and into the cabin, where it was at once contaminated by the now almost unbreathable atmosphere.
Pat had never known time to move so slowly. It seemed quite incredible that only four hours had passed since he and McKenzie had been left to guard their sleeping companions. He could have sworn that they had been here for days, talking quietly together, calling Port Roris every fifteen minutes, checking pulses and respiration, and doling out oxygen with a miserly hand.
But nothing lasts forever. Over the radio, from the world which neither man really believed he would ever see again, came the news they had been waiting for.
We're on the way, said the weary but determined voice of Chief Engineer Lawrence. You only have to hang on for another hour we'll be on top of you by then. How are you feeling?
Very tired, said Pat slowly. But we can make it.
And the passengers?
Just the same.
Right I'll call you every ten minutes. Leave your receiver on, volume high. This is Med Division's idea they don't want to risk your falling asleep.
The blare of brass thundered across the face of the Moon, then echoed on past the Earth and out into the far reaches of the solar system. Hector Berlioz could never have dreamed that, two centuries after he had composed it, the soul-stirring rhythm of his Rakoczy March would bring hope and strength to men fighting for their lives on another world.
As the music reverberated round the cabin, Pat looked at Dr. McKenzie with a wan smile.
It may be old-fashioned, he said, but it's working.
The blood was pounding in his veins, his foot was tapping with the beat of the music. Out of the lunar sky, flashing down from space, had come the tramp of marching armies, the thunder of cavalry across a thousand battlefields, the call of bugles that had once summoned nations to meet their destiny. All gone, long ago, and that was well for the world. But they had left behind them much that was fine and noble examples of heroism and self-sacrifice, proofs that men could still hold on when their bodies should have passed the limits of physical endurance.
As his lungs labored in the stagnant air, Pat Harris knew that he had need of such inspiration from the past, if he was to survive the endless hour that lay ahead.
Aboard the tiny, cluttered deck of Duster One, Chief Engineer Lawrence heard the same music, and reacted in the same fashion. His little fleet was indeed going into battle, against the enemy that Man would face to the end of time. As he spread across the Universe from planet to planet and sun to sun, the forces of Nature would be arrayed against him in ever new and unexpected ways. Even Earth, after all these aeons, still had many traps for the unwary, and on a world that men had known for only a lifetime, death lurked in a thousand innocent disguises. Whether or not the Sea of Thirst was robbed of its prey, Lawrence was sure of one thing tomorrow there would be a fresh challenge.
Each ski was towing a single sledge, piled high with equipment which looked heavier and more impressive than it really was; most of the load was merely the empty drums upon which the raft would float. Everything not absolutely essential had been left behind. As soon as Duster One had dumped its cargo, Lawrence would send it straight back to Port Rons for the next load. Then he would be able to maintain a shuttle service between the site and Base, so that if he wanted anything quickly he would never have to wait more than an hour for it. This, of course, was taking the optimistic view; by the time he got to Selene, there might be no hurry at all.
As the Port buildings dropped swiftly below the sky line, Lawrence ran through the procedure with his men. He had intended to do a full-dress rehearsal before sailing, but that was another plan that had had to be abandoned through lack of time. The first count-down would be the only one that mattered.
Jones, Sikorsky, Coleman, Matsul, when we arrive at the marker, you're to unload the drums and lay them out in the right pattern. As soon as that's done, Bruce and Hodges will fix the cross-members. Be very careful not to drop any of the nuts and bolts, and keep all your tools tied to you. If you accidentally fall off, don't panic; you can only sink a few centimeters. I know.
Sikorsky, Jones, you give a hand with the flooring as soon as the raft framework's fixed. Coleman, Matsui, immediately there's enough working space, start laying out the air pipes and the plumbing. Greenwood, Renaldi, you're in charge of the drilling operation
So it went on, point by point. The greatest danger, Lawrence knew, was that his men would get in each other's way as they worked in this confined space. A single trifling accident, and the whole effort would be wasted. One of Lawrence 's private fears, which had been worrying him ever since they left Port Roris, was that some vital tool had been left behind. And there was an even worse nightmare that the twenty-two men and women in Selene might die within minutes of rescue because the only wrench that could make the final connection had been dropped overboard.
On the Mountains of Inaccessibility, Maurice Spenser was staring through his binoculars and listening to the radio voices calling across the Sea of Thirst. Every ten minutes Lawrence would speak to Selene, and each time the pause before the reply would be a little longer. But Harris and McKenzie were still clinging to consciousness, thanks to sheer will power and, presumably, the musical encouragement they were getting from Clavius City.
What's that psychologist disc jockey pumping into them now? asked Spenser. On the other side of the control cabin, the ship's Radio Officer turned up the volume, and the Valkyries rode above the Mountains of Inaccessibility.
I don't believe, grumbled Captain Anson, that they've played anything later than the nineteenth century.
Oh yes they have, corrected Jules Braques, as he made some infinitesimal adjustment to his camera. They did Khachaturian's 'Sabre Dance' just now. That's only a hundred years old.
Time for Duster One to call again, said the Radio Officer. The cabin became instantly silent.
Right on the second, the dust-ski signal came in. The expedition was now so close that Auriga could receive it directly, without benefit of the relay from Lagrange.
Lawrence calling Selene. We'll be over you in ten minutes. Are you O. K.?
Again that agonizing pause; this time it lasted almost five seconds. Then:
Selene answering. No change here.
That was all. Pat Harris was not wasting his remaining breath.
Ten minutes, said Spenser. They should be in sight now. Anything on the screen?
Not yet, answered Jules, zooming out to the horizon and panning slowly along its empty arc. There was nothing above it but the black night of space.
