its lockstep way with total concentration and a kind of mystic intensity. McCulloch did not intrude. He felt as though he had been left alone in the body they shared.
As they marched, he concentrated on observing, since he could not interrogate. And there was much to see; for the longer he dwelled within his host, the more accustomed he grew to the lobster’s sensory mechanisms. The compound eyes, for instance. Enough of his former life had returned to him now so that he remembered human eyes clearly, those two large gleaming ovals, so keen, so subtle of focus, set beneath protecting ridges of bone. His host’s eyes were nothing like that: they were two clusters of tiny lenses rising on jointed, movable stalks, and what they showed was an intricately dissected view, a mosaic of isolated points of light. But he was learning somehow to translate those complex and baffling images into a single clear one, just as, no doubt, a creature accustomed to compound-lens vision would sooner or later learn to see through human eyes, if need be. And McCulloch found now that he could not only make more sense out of the views he received through his host’s eyes, but that he was seeing farther, into quite distant dim recesses of this sunless undersea realm.
Not that the stalked eyes seemed to be a very important part of the lobster’s perceptive apparatus. They provided nothing more than a certain crude awareness of the immediate terrain. But apparently the real work of perceiving was done mainly by the thousands of fine bristles, so minute that they were all but invisible, that sprouted on every surface of his host’s body. These seemed to send a constant stream of messages to the lobster’s brain: information on the texture and topography of the ocean floor, on tiny shifts in the flow and temperature of the water, of the proximity of obstacles, and much else. Some of the small hairlike filaments were sensitive to touch and others, it appeared, to chemicals; for whenever the lobster approached some other life-form, it received data on its scent—or the underwater equivalent—long before the creature itself was within visual range. The quantity and richness of these inputs astonished McCulloch. At every moment came a torrent of data corresponding to the landslide senses he remembered, smell, taste, touch; and some central processing unit within the lobster’s brain handled everything in the most effortless fashion.
But there was no sound. The ocean world appeared to be wholly silent. McCulloch knew that that was untrue, that sound waves propagated through water as persistently as through air; indeed, faster. Yet the lobster seemed neither to possess nor to need any sort of auditory equipment. The sensory bristles brought in all the data it required. The “speech” of these creatures, McCulloch had long ago realized, was effected not by voice but by means of spurts of chemicals released into the water, hormones, perhaps, or amino acids, something of a distinct and readily recognizable identity, emitted in some high-redundancy pattern that permitted easy recognition and decoding despite the difficulties caused by currents and eddies. It was, McCulloch thought, like trying to communicate by printing individual letters on scraps of paper and hurling them into the wind. But it did somehow seem to work, however clumsy a concept it might be, because of the extreme sensitivity of the lobster’s myriad chemoreceptors.
The antennae played some significant role also. There were two sets of them, a pair of three-branched ones just behind the eyes and a much longer single-branched pair behind those. The long ones restlessly twitched and probed inquisitively and most likely, he suspected, served as simple balancing and coordination devices much like the whiskers of a cat. The purpose of the smaller antennae eluded him, but it was his guess that they were involved in the process of communication between one lobster and another, either by some semaphore system or in a deeper communion beyond his still awkward comprehension.
McCulloch regretted not knowing more about the lobsters of his own era. But he had only a broad general knowledge of natural history, extensive, fairly deep, yet not good enough to tell him whether these elaborate sensory functions were characteristic of all lobsters or had evolved during the millions of years it had taken to create the water-world. Probably some of each, he decided. Very likely even the lobsters of the former world had had much of this scanning equipment, enough to allow them to locate their prey, to find their way around in the dark sub-oceanic depths, to undertake their long and unerring migrations. But he found it hard to believe that they could have had much “speech” capacity, that they gathered in solemn sessions to discuss abstruse questions of theology and mythology, to argue gently about omens and heralds and the end of all things. That was something that the patient and ceaseless unfoldings of time must have wrought.
The lobsters marched without show of fatigue: not scampering in that dancelike way that his host had adopted while summoning its comrades to save it from the swimming creature, but moving nevertheless in an elegant and graceful fashion, barely touching the ground with the tips of their legs, going onward, step by step by step, steadily and fairly swiftly.
McCulloch noticed that new lobsters frequently joined the procession, cutting in from left or right just ahead of his host, who always remained at the rear of the line; that line now was so long, hundreds of lobsters long, that it was impossible to see its beginning. Now and again one would reach out with its bigger claw to seize some passing animal, a starfish or urchin or small crab, and without missing a step would shred and devour it, tossing the unwanted husk to the cloud of planktonic scavengers that always hovered nearby. This foraging on the march was done with utter lack of self-consciousness; it was almost by reflex that these creatures snatched and gobbled as they journeyed.
And yet all the same they did not seem like mere marauding mouths. From this long line of crustaceans there emanated, McCulloch realized, a mysterious sense of community, a wholeness of society, that he did not understand but quite sharply sensed. This was plainly not a mere migration but a true pilgrimage. He thought ruefully of his earlier condescending view of these people, incapable of achieving the Taj Mahal or the Sistine Chapel, and felt abashed: for he was beginning to see that they had other accomplishments of a less tangible sort that were only barely apparent to his displaced and struggling mind.
“When you come back,” Maggie said, “you’ll be someone else. There’s no escaping that. It’s the one thing I’m frightened of. Not that you’ll die making the hop, or that you’ll get into some sort of terrible trouble in the future, or that we won’t be able to bring you back at all, or anything like that. But that you’ll have become someone else.”
“I feel pretty secure in my identity,” McCulloch told her.
“I know you do. God knows, you’re the most stable person in the group, and that’s why you’re going. But even so. Nobody’s ever done anything like this before. It can’t help but change you. When you return, you’re going to be unique among the human race.”
“That sounds very awesome. But I’m not sure it’ll matter that much, Mag. I’m just taking a little trip. If I were going to Paris, or Istanbul, or even Antarctica, would I come back totally transformed? I’d have had some new experiences, but—”
“It isn’t the same,” she said. “It isn’t even remotely the same.” She came across the room to him and put her hands on his shoulders, and stared deep into his eyes, which sent a little chill through him, as it always did; for when she looked at him that way there was a sudden flow of energy between them, a powerful warm rapport rushing from her to him and from him to her as though through a huge conduit, that delighted and frightened him both at once. He could lose himself in her. He had never let himself feel that way about anyone before. And this was not the moment to begin. There was no room in him for such feelings, not now, not when he was within a couple of hours of leaping off into the most unknown of unknowns. When he returned—if he returned—he might risk allowing something at last to develop with Maggie. But not on the eve of departure, when everything in his universe was tentative and conditional. “Can I tell you a little story, Jim?” she asked.
“Sure.”
“When my father was on the faculty at Cal, he was invited to a reception to meet a couple of the early astronauts, two of the Apollo men—I don’t remember which ones, but they were from the second or third voyage to the Moon. When he showed up at the faculty club, there were two or three hundred people there, milling around having cocktails, and most of them were people he didn’t know. He walked in and looked around and within ten seconds he had found the astronauts. He didn’t have to be told. He just
