anything.
The doctor said, "Maybe the gas in these pockets is so concentrated that
it gives back a sound indistinguishable from that of water. If such is
the case this gas under pressure will be much heavier, volume for volume,
than air, so that we will not gain very much in buoyancy. Perhaps we
have sunk so deeply that water pressure has increased to the extent that
it will not allow the gas to expand. Or perhaps the gas is forcing the
water out, but at the same rate as the water forced its way in, which
was very gradually over the space of many days. If that is the case we
may not be able to regain our buoyancy in time -- "
"Doctor," said Dickson angrily, "don't be so blasted optimistic!"
It seemed that there were to be no helpful ideas from either of them,
and Wallis knew suddenly that it had been a mistake to stop and talk
like this, that anything which gave them time to think too deeply about
their predicament was a mistake. As the superior officer his display of
indecision had not helped things, either.
"We have seven more faucets and a practically unlimited supply of acetylene,"
he said firmly. "We must keep trying."
Sometime later -- the doctor estimated it at between twenty and thirty hours,
but Dickson, who had had nothing much to occupy him in his litter except
holding torches and occasionally talking to Jenny, insisted that it was
more like three days -- they had to stop trying through sheer fatigue.
Despite recent practice each installation had begun to take more time.
Radford fumbled his job with the plugs and staggered around the place as
if he were half-drunk, and Wallis, through sheer carelessness, neglected
to cover his face with the sacking mask and cowl, the result being a
scalded forehead. It wasn't a very serious injury, but the cold made
it sting.
Back in the sick bay they found the two girls asleep and Dickson wide awake,
his teeth clenched tightly, sweating and staring into the darkness above him.
He did not look at them or reply when they spoke. Radford shook two tablets
out of a bottle, hesitated, then made it four. He said, "You need to go
to sleep, Mr. Dickson."
To Wallis he said, "One good thing about all this is that we've been working
so hard that we are going to go to sleep warm for a change."
But Wallis did not go to sleep at once or, at first, completely. They had
closed all taps and disconnected all the acetylene tanks before returning
to the sick bay, but there was still an awful lot of bubbling and gurgling
going on all over the ship. Wallis tried to tell himself that this was
a good sign, but then he would contrast the total air space within the
tanks with the relatively tiny amount by which they hoped to increase
it and he would wonder if it was enough. He would argue then that the
tanker had been drifting close to the surface for more than a week and if
it was sinking only now, it must be sinking very slowly and that surely
a minute increase in over-all buoyancy would tip the balance.
But he did not know for certain, and while his mind argued wearily to
itself it began to drift more and more frequently into sleep -- a sleep
composed of a series of brief, terrifying nightmares in which his fear
became reality and where the bubbling and gurgling noises became the
sounds of their hull breaking up and a solid mass of water crashed down
on them and they tore at the metal walls around them and at each other
with their bare hands and screamed and screamed. . . .
Eventually his body's weariness would not let him wake himself from these
nightmares and somewhere along the way they changed. Wallis dreamed that
he was on the bridge of a destroyer somewhere in the Med, to judge by
the weather. It was a very pleasant dream, sheer wish-fulfillment. The
sky was blue and cloudless, the sea calm with a slight swell, the sun
was hot even through his whites, and a patch of sunburn on his forehead
itched slightly just to remind him that this wasn't
