A few minutes later Harrison took off, leaving the two doctors standing beside their drilling rig. Edwards said, “I see what you mean, Doctor. You want to attract attention to us. ‘X’ marks the spot and an 'X' with closed ends is a figure-eight. Persistency of vision will do the rest.”
The scout ship was criss-crossing above them in the tightest turns Conway had ever seen. Even with the ship’s gravity compensators working at full capacity Harrison must have been taking at least four Gs. On the ground the ship’s shadow whipped past and around them, trailing a long, bright yellow line of rolled-up leaves. The ground shook to the thunder of the tiny vessel’s jet and then, very slightly, it began shaking by itself.
“Harrison!”
The scout ship broke off the maneuver and roared into a landing behind them. By then the ground was already beginning to sag.
Suddenly they appeared.
Two large, flat metal disks embedded vertically in the ground, one about twenty feet in front of them and the other the same distance behind. As they watched each disk contracted suddenly into a shapeless blob of metal which crawled a few feet to the side and then suddenly became a large, razor-edged disk again, cutting a deep incision in the ground. The disks had each cut more than a quarter circle around them and the ground was sagging rapidly inside the incisions before Conway realized what was happening.
“Think cubes at them!” he yelled. “Think something blunt! Harrison!”
“Lock’s open. Come running.”
But they could not run without taking their eyes and minds off the disks, and if they did that they could not run fast enough to clear the circular incision which was being made around them. Instead they sidled toward the scout ship, willing every inch of the way that the disks become cubes or spheres or horseshoes-anything but the great, circular scalpels which something had made them become.
At Sector General Conway had watched his colleague Mannon perform incredible feats of surgery, using one of these thought-controlled tools, an all-purpose surgical instrument which became anything he wanted it to be instantly. Now two of the things were crawling and twisting like metallic nightmares as they tried to shape them one way and something else-which was their owner and as such had more expertise-tried to shape them another. It was a very one-sided struggle but they did, just barely, manage to hamper their opponent’s thinking enough to allow them to get clear before the circular plug of “skin” containing the drilling rig and other odds and ends of equipment dropped from sight.
“They’re welcome to it,” said Major Edwards as the lock slammed shut and Harrison lifted off. “After all, we’ve been taking specimens for weeks and it may give them something to think about before we broaden contact with shadow diagrams.” He grew suddenly excited as he went on, “With high-acceleration radio-controlled missiles we can build up quite complex figures!”
Conway said, “I was thinking more in terms of a tight beam of light projected onto the surface at night. The leaves should react by opening and the beam could be moved very quickly in a rectangular sweep pattern like old-fashioned TV. It might even be possible to project moving pictures.”
“That’s it,” said Edwards enthusiastically. “But how a dirty great beast the size of a county, who doesn’t have arms, legs or anything else, will be able to answer our signals is another matter. Probably it will think of something.”
Conway shook his head. “It is possible that despite their slow movements the carpets are capable of quick thinking, that they are in fact the tool users we are looking for and that their enormous bodies undergo voluntary surgery whenever they want to draw in and examine a specimen which is not within reach of a mouth. But I prefer the theory of a smaller, intelligent life-form inside or under the big one, an intelligent parasite perhaps which helps maintain the host in good health by the use of the tools and other abilities, and which makes use of the host being’s 'eyes’ as well as everything else. You can take your pick.”
There was silence while the scout ship leveled off on a course which would take it back to the mother ship, then Harrison said, “We haven’t made direct contact, then-we’ve just put squiggles on a vegetable radar screen? But it is still a big step forward.”
“As I see it,” said Conway, “if tools were being used to bring us to them, they must be a fair distance from the surface-perhaps they can’t exist on the surface. And don’t forget they would use the carpet exactly as we use vegetable and mineral resources. How would they analyze life samples? Would they be able to see them at all down there? They use plants for eyes but I can’t imagine a vegetable microscope. Perhaps they would use the big beastie’s digestive juices in certain stages of the analysis.
Harrison was beginning to look a little green around the gills. He said, “Let’s send down a robot sensor first, to see what they do, eh?”
Conway began, “This is all theory …
He broke off as the ship’s radio hummed, cleared its throat and said
briskly, “Scout ship Nine. Mother here. I have an urgent signal for Doctor
Conway. The being Camsaug has gone on vacation wearing the tracer the
Doctor gave it. It is heading for the active stretch of shore in area
H-Twelve. Harrison, have you anything to report?”
“Yes, indeed,” replied the Lieutenant, glancing at Conway. “But first I think the Doctor wants to speak to you.”
Conway spoke briefly and a few minutes later the scout ship leaped ahead under emergency thrust, ripping through the sky too fast for even the leaves to react to its shadow and trailing an unending shock wave which would have deafened anything on the surface with ears to hear. But the great carpet slipping past them might well number deafness among its many other infirmities which now, Conway thought angrily, included a number of well-developed and extensive skin cancers and God alone knew what else.
He wondered if a great, slow-moving creature like this could feel pain, and if so, how much? Was the condition he could see confined to hundreds of acres of “skin” or did it go much deeper? What would happen to the beings living in or under it if too many of the carpets died, decomposed? Even the rollers with their offshore culture would be affected-the ecology of the whole planet would be wrecked! Somebody was going to have to talk to the rollers, politely but very, very firmly, if it wasn’t already too late.
All at once the horse-trading aspect of his assignment, the swapping of tools for medical assistance, was no longer important. Conway was beginning to think like a doctor again, a doctor with a desperately ill patient.
At Descartes the copter he had requested was waiting. Conway changed into a lightweight suit with a propulsion motor strapped onto his back and extra air tanks on his chest. Camsaug had too great a lead for him to follow on foot, so Conway would fly out to the being’s present position by helicopter. Harrison was at the controls.
“You again,” said Edwards.
The Lieutenant smiled. “This is where the action is. Hold tight.”
After the mad dash to the mother ship the helicopter trip seemed incredibly slow. Conway felt that he would fall flat on his face if it did not speed up and Edwards assured him that the feeling was mutual and that they would have made better time swimming. They watched Camsaug’s trace grow larger in the search screen while Harrison cursed the birds and flying lizards diving for fish and suiciding on his rotor blades.
They flew low over the settled stretch of coast where the shallows were protected from the large predators of the sea by a string of offshore islands and reefs. To this natural protection the rollers had added a landward barrier of dead land-beast by detonating a series of low-power nuclear devices inside the vast creature’s body. The area was now so settled that doughnuts could roll with very little danger far inside the beast’s cavernous mouths and prestomachs and out again.
