Williamson nodded, but hesitated before he spoke. “We can be in position at that time, Doctor, but something else has just come up which may cause you to change your mind about the timing.”
He gestured toward the screen and went on, “I can show you charts and figures, if you like, but it is quicker to tell you the results first. The survey of healthy and less ill strata creatures which you asked our cultural contact people to carry out-your idea being that it might be easier to establish communications with a being who was not in constant pain than otherwise-is now complete. Altogether eighteen hundred and seventy-four sites covering every known strata creature were visited, a tool left unattended on the surface and kept under observation from a distance for periods of up to six hours. Even though the body material was practically identical with that of our patient, including the presence of a somewhat simplified form of eye plant, the results were completely negative. The strata creatures under test made no attempt to control or change the tools in any way, and the small changes which did occur were directly traceable to mental radiation from birds or nonintelligent surface animals. We fed this data to Descartes’ computer and then to the tactical computer on Vespasian. The conclusions left no doubt at all, I’m afraid.
“There is only one intelligent strata creature on Drambo,” Williamson ended grimly, “and it is our patient.”
Conway did not reply at once and the meeting became more and more disorganized. To begin with there were a few useful ideas put up-at least, they sounded good until the Captain shot them down. But then instead of ideas he got senseless arguments and bad temper and suddenly Conway knew why.
They had all been both overworked and overtired when the meeting had started, and that had been five hours ago. The Melfan’s bony underside was sagging to within a few inches of the deck. The Hudlar was probably hungry because the water inside the hold had been cleared of all edible material as had the floor, which would similarly displease the constantly rolling Drambon. Above them the enormous Chalder had been hanging in a cramped position for far too long, and the other Earth humans must have been finding their pressure suits as irksome as Conway was finding his. It was obvious that there would be no more useful contributions from anyone at this meeting, including himself, and it was time to wind it up.
He signaled for silence, then said, “Thank you, everyone. The news that our patient is the planet’s only intelligent strata creature makes it necessary for us to try even harder, if that is possible, to make the forthcoming operation a success. It is not a valid reason for delaying surgery.
“You will all have plenty to occupy you tomorrow,” he ended. “I shall spend the time making one last try at obtaining the consent and cooperation of our patient.”
Modifications had been completed to a pair of the tracked boring machines just three days earlier, making them as foolproof as possible and extending their two-way vision equipment to allow Conway to view and, if necessary, direct the operation from anywhere on or inside the strata creature. It was the communications gear that he checked first.
“I have no intention of becoming a dead hero,” Conway explained, grinning. “If we are in any danger I shall be the first to scream for help.”
Harrison shook his head. “The second.”
“Ladies first,” said Murchison firmly.
They drove inland to a healthy area thickly covered by eye plants and stopped for a full hour, then moved on for an hour and stopped again. They spent the morning and early afternoon moving and stopping with no discernible reaction from the patient. Sometimes they drove around in tight circles in an attempt to attract attention, still without success. Not a single tool appeared. Their ground sensors gave no sign that anything was trying to undercut them. Altogether it was turning out to be an intensely frustrating if physically restful day.
When darkness fell they switched on the digger’s spotlights and played them around and watched thousands of eye plants open and close suddenly to this artificial sunshine, but still the strata creature refused the bait.
“In the beginning the brute must have been curious about us,” said Conway, “and anxious to investigate any strange object or occurrence. Now it is simply frightened and hostile, and there are much better targets elsewhere.”
The digger’s vision screens showed several transfusion and feeding sites under constant tool attack, and too many dark stains on the ground which were not of oil.
“I still think,” said Conway seriously, “that if we could get close to its brain, or even into the area where the tools are produced, we would stand a better chance of communicating directly. If direct communication is impossible we might be able to artificially stimulate certain sections to make it think that large objects had landed on the surface, forcing it to draw off the tools attacking the transfusion installations. Or if we could gain an understanding of its technology that might give us a lever …”
He broke off as Murchison shook her head. She produced a chart comprising thirty or more transparent overlays which showed the patient’s interior layout as accurately as six months’ hard work with insufficient facilities could make it. Her features fell into their lecturing expression, the one which said that she wanted attention but not admiration.
She said, “We have already tried to find the patient’s brain location by backtracking along the nerve paths — that is, the network of rootlets containing metallic salts which are capable of carrying electrochemical impulses. Using test bores taken at random on the top surface and by direct observation from diggers, we found that they link up, not to a central brain, but to a flat layer of similar rootlets lying just above the subsurface. They do not join directly onto this new network, but lie alongside, paralleling it close enough for impulses to be passed across by induction.
“Some of this network is probably responsible for the subsurface muscular contractions which gave the patient mobility before it took over this particular land mass and stopped climbing over and smothering its enemies, and it is natural to assume that the eye plants above and the muscles below has a direct connection since they would give the first warning of another strata creature attempting to slip over this one, and the subsequent muscular reaction would be almost involuntary.
“But there are many other root networks in that layer,” she went on, “whose function we do not know. They are not color coded-they all look exactly the same except for minute variations in thickness. The type which apparently abstracts minerals from the subsurface rock can vary in thickness. So I would advise against artificial stimulation of any kind. You could very easily start a bunch of subsurface muscles to twitching, and the corpsmen up top would have localized earthquakes to contend with as well as everything else.”
“All right,” said Conway irked for no other reason than that her objections were valid. “But I still want to get close to its brain or to the tool-producing area, and if it won’t pull us in we must go looking for it. But we’re running out of time. Where, in your opinion, is the best place to look?”
She was thoughtful for a moment, then said, “Either the brain or the tool-producing area could be in a hollow or small valley in the subsurface where, presumably, the creature absorbs necessary minerals. There is a large, rocky hollow fifteen miles away, just here, which would give the necessary protection from below and from all sides while the mass of the overlaying body would save it from injury from above. But there are dozens of other sites just as good. Oh, yes, there would have to be a constant supply of nutriment and oxygen available, but as this is a quasi vegetable process in the patient with water instead of blood as the working fluid, there should be no problem in supplying a deeply buried brain …
