“Speak for yourself,” she said.
“Seriously,” Conway said, “I’m beginning to wonder if the strata creature itself is highly intelligent…
They landed shortly afterward and stepped carefully onto the springy ground, crushing several of the vegetable eyes with every few yards of progress. The fact that the patient had countless millions of other eyes did not make them feel any better about the damage inflicted by their feet.
When they were about fifty yards from the ship, she said suddenly, “If these plants are eyes-and it is a natural assumption, since they are sensitive to light-why should it have so many in an area where danger threatens so seldom? Peripheral vision to coordinate the activity of its feeding mouths would be much more useful.”
Conway nodded. They knelt carefully among the plants, their long shadows filled with the yellow of tightly closed leaves. He indicated their tracks from the entry lock of the ship, which were also bright yellow, and moved his arms about so as to partly obscure some of the plants from the light. Leaves partially in shade or suffering even minor damage reacted exactly as those completely cut off from the light. They rolled up tight to display their yellow undersides.
“The roots are thin and go on forever,” he said, excavating gently with his fingers to show a whitish root which narrowed to the diameter of thin string before disappearing from sight. “Even with mining equipment or during exploratories with diggers we haven’t been able to find the other end of one. Have you learned anything new from the internals?”
He covered the exposed root with soil, but kept the palms of both hands pressed lightly against the ground.
Watching him, she said, “Not very much. Light and darkness, as well as causing the leaves to open out or roll up tight, causes electrochemical changes in the sap, which is so heavily loaded with mineral salts that it makes a very good conductor. Electrical pulses produced by these changes could travel very quickly from the plant to the other end of the root. Er, what are you doing, dear, taking its pulse?”
Conway shook his head without speaking, and she went on. “The eye plants are evenly distributed over the patient’s top surface, including those areas containing dense growths of the air-renewal and waste-elimination types, so that a shadow or light stimulus received anywhere on its surface is transmitted quickly-almost instantaneously, in fact-to the central nervous system via this mineral-rich sap. But the thing which bothers me is what possible reason could the creature have for evolving an eyeball several hundred miles across?”
“Close your eyes,” said Conway, smiling. “I’m going to touch you. As accurately as you can, try to tell me where.”
“You’ve been too long in the company of men and e-ts, Doctor,” she began, then broke off, looking thoughtful.
Conway began by touching her lightly on the face, then he rested three fingers on top of her shoulder and went on from there.
“Left cheek about an inch from the left side of my mouth,” she said. “Now you’ve rested your hand on my shoulder. You seem to be rubbing an X onto my left bicep. Now you have a thumb and two, maybe three, fingers at the back of my neck just on the hairline… Are you enjoying this? I am.”
Conway laughed. “I might if it wasn’t for the thought of Lieutenant Harrison watching us and steaming up the pilot’s canopy with his hot little breath. But seriously, you see what I’m getting at, that the eye plants have nothing to do with the creature’s vision but are analogous to pressure- , pain- or temperature-sensitive nerve endings?”
She opened her eyes and nodded. “It’s a good theory, but you don’t look happy about it.”
“I’m not,” said Conway sourly, “and I’d like you to shoot as many holes in it as possible. You see, the complete success of this operation depends on us being able to communicate with the beings who produced the thought-controlled tools. Up until now I had assumed that these beings would be comparable in size to ourselves even if their physiological classification would be completely alien, and that they would possess the usual sensory equipment of sight, hearing, taste, touch and be capable of being reached through any or all of these channels. But now the evidence is piling up in favor of a single intelligent life-form, the strata creature itself, which is naturally deaf, dumb and blind so far as we can see. The problem of communicating even the simplest concepts to it is-“
