The digger lurched and for an instant Conway felt a sensation impossible in these surroundings, that of free fall. Then there was a crash as the vehicle struck rocky ground. It landed on its side, rolled over twice and moved forward again, but skidding and slewing to one side. The sound of tools striking the hull was deafening.
Two vertical creases appeared on the Fleet Commander’s forehead. He said, “Having trouble, Doctor?”
The constant banging of tools made it hard to think. Conway nodded and said, “I didn’t expect the seals to be attacked, but now I realize that the patient is simply trying to defend itself where it thinks it is under the heaviest attack. I also realize now that its sense of touch is not restricted to its top surface. You see, it is blind, deaf and dumb but it seems to be able to feel in three dimensions. The eye plants and subsurface root networks allow it to feel areas of local pressure, but vaguely, without detail. To feel the fine details it sends tools, which are extremely sensitive- sensitive enough to feel the airflow over their wings in the glider configuration and reproduce the shape themselves at will. Our patient learns very quickly and that glider I thought at it has cost a lot of lives. I wish-”
“Doctor Conway,” the Fleet Commander broke in harshly. “You are
either trying to make excuses or giving me a very basic lecture with which
I am already familiar. I have time to listen to neither. We are faced with
a surgical and tactical emergency. I require guidance.”
Conway shook his head violently. He had the feeling that he had just said or thought of something important but he did not know what it was. He had to stay with his present train of thought if he expected to drag it out into the light again.
He went on, “The patient sees, experiences everything, by touch. So far our only area of common contact are the tools. They are thought controlled extensions of its sense of touch throughout and for a short distance above the patient’s body. Our own mental radiation and control are more concentrated and of strictly limited range. The situation has been that of two fencers trying to communicate only through the tips of their foils-”
He stopped abruptly because he was talking to an empty screen. All three repeaters glowed with power, but there was neither sound nor vision.
Harrison shouted, “I was afraid of this, Doctor. We strengthened the hull armor but had to cover the antenna housing with a plastic radome to allow two-way communications. The tools have found our weak spot. Now we are deaf, dumb and blind, too-and missing one leg because our port caterpillar tread won’t work.”
The digger had come to rest on a flat shelf of rock in a large cavern which angled steeply into the subsurface. Above and behind them hung a great mass of the creature’s body material from which there was suspended thousands of rootlets which joined and rejoined until they became thick, silvery cables writhing motionlessly across the cavern floor, walls and roof before disappearing into the depths. Each cable had at least one bud sprouting from it, like a leaf of wrinkled tinfoil. The more well developed buds quivered and were trying to take the shapes of the tools which were attacking the digger.
“This is one of the places where it makes the tools,” she said, using a spotlight as pointer, “or should I say grows them-I still can’t decide whether this is an animal or vegetable life-form basically. The nervous system seems to be centered in this area, so it is almost certainly part of the brain as well. And it is sensitive-do you see how carefully the tools avoid those silver cables while they are attacking?”
“We’ll do the same,” said Conway, then to Harrison, “That is, if you can move the digger on one track to that overhanging wall with the cables running along it, without crushing those two on the floor?”
Damage in this sensitive area could have serious effects on their patient.
The Lieutenant nodded and began rocking the digger forward and backward along the shelf until they were tight against the indicated wall. Protected by the sensitive cables above, the cavern floor below and the rocky wall on their starboard side, the tool attack was confined to their unprotected port side. They could once again hear themselves think, but Harrison pointed out firmly but apologetically that they could not climb the slope or dig their way out on one track, that they could not call for help and that they had air for only fourteen hours and then only if they sealed their suits to use their remaining tanked air.
