But of course they had not anticipated sending him so eerily far across the dark abysm of time, into a world in which humankind and all its works were not even legendary memories, and the host who would receive him was a calm and thoughtful crustacean capable of taking him in with only the most mild and brief disruption of its serenity.
The lobsters, he noticed now, had reconfigured themselves while his mind had been drifting. They had broken up their circle and were arrayed in a long line stretching over the ocean floor, with his host at the end of the procession. The queue was a close one, each lobster so close to the one before it that it could touch it with the tips of its antennae, which from time to time they seemed to be doing; and they all were moving in a weird kind of quasi-military lockstep, every lobster swinging the same set of walking-legs forward at the same time.
Where are we going? McCulloch asked his host.
—The pilgrimage has begun.
—What pilgrimage is that?
—To the dry place, said the host. To the place of no water. To the land.
—Why?
—It is the custom. We have decided that the time of the Molting of the World is soon to come; and therefore we must make the pilgrimage. It is the end of all things. It is the coming of a newer world. You are the herald; so we have agreed.
—Will you explain? I have a thousand questions. I need to know more about all this, McCulloch said.
—Soon. Soon. This is not a time for explanations.
McCulloch felt a firm and unequivocal closing of contact, an emphatic withdrawal. He sensed a hard ringing silence that was almost an absence of the host, and knew it would be inappropriate to transgress against it. That was painful, for he brimmed now with an overwhelming rush of curiosity. The Molting of the World? The end of all things? A pilgrimage to the land? What land? Where? But he did not ask. He could not ask. The host seemed to have vanished from him, disappearing utterly into this pilgrimage, this migration, moving in 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.
