Unctuous ripples moved away from him; lenses of quince-colored light formed and vanished.

The toes over Reith's head clicked on the gunwale. They shifted their position. Reith, lips drawn away from his teeth in a ghastly grimace, lunged up with his right arm. He caught a thin hard ankle, pulled. The Pnume croaked in dismal consternation. It teetered forward and for a moment leaned at an incredible angle, almost horizontal, supported only by the grip of its toes. Then it fell into the water.

Zap 210 clutched at Reith. "Don't let it touch you; it will pull you apart."

"Can it swim?"

"No," she said through chattering teeth. "It is heavy; it will sink."

Reith said, "Climb up on my back, take hold of the gunwale, pull yourself aboard the barge."Gingerly she swung behind him. Her feet pushed against his back; she stood on his shoulder, then clambered aboard the barge. Reith laboriously heaved himself up after her to lie on the deck, totally spent.

Presently he gained his feet, to peer toward the dock. The Pnumekin worked as before.

Reith moved back into the shadows. Zap 210 had not moved. The shift clung to her underdeveloped body. She was not ungraceful, reflected Reith.

She noticed his attention and huddled back against the cargo.

"Take off your undergown and put on your cloak," Reith suggested.

"You'll be warmer."

She stared at him miserably. Reith pulled off his own sodden garments.

In horror almost as intense as she had shown toward the Pnume, she jerked herself around. Reith found the energy for a sour grin. With her back turned she draped the cloak over her shoulders and by some means unknown divested herself of her undergarments.

The barge vibrated, lurched. Reith looked past the cargo to see the dock receding. It became an oasis of light in the heavy blackness. Far ahead showed a wan blue glimmer toward which the barge silently moved.

They were underway. Behind lay Pagaz Zone and the way to Foreverness. Ahead was darkness and the Northern Areas.

CHAPTER FOUR.

THE BARGE CARRIED a crew of two, who kept to the ap.r.o.n at the bow of the barge. Here was a small pantry, a cook-bench, an island of dim yellow illumination. There seemed to be at least two other pa.s.sengers aboard, perhaps as many as three or four, who were even less obtrusive than the crew, and manifested themselves only at the pantry and the cook- bench. The food seemed to be free to the use of all. Zap 210 would not allow Reith to go forward for food. When the pantry and cook-bench were not in use Zap 210 procured food for both: cakes of pilgrim-pod meal, candied plum-shaped objects which might have been fruit or possibly leech-like insects, bars of meat-paste, sweet and salty wafers of a delicate crisp white substance which Zap 210 considered a delicacy, but which left an unpleasant aftertaste in Reith's mouth.

Time pa.s.sed: how long Reith had no way of knowing. The lake became a river which in turn became an underground ca.n.a.l fifty or sixty feet wide.

The barge moved without a sound, propelled, so Reith guessed, by electric fields cycling along the keel. Ahead gleamed a dim blue light serving as a fix for the barge's steering sensor; when one blue light pa.s.sed overhead, another always shone far ahead. At long intervals the barge pa.s.sed lonesome little piers and docks, with pa.s.sages leading away into unknown fastnesses.

Reith ate and slept; how many times he lost count. His cosmos was the barge, the dark, the unseen water, the presence of Zap 210. With nothing but time and boredom, Reith set himself to the task of exploring her personality. Zap 210, on her part, treated Reith with suspicion, as if begrudging even the intimacy of conversation: a skittishness and prim reserve peculiar in a person who, to the best of his knowledge, had not even a distorted understanding of ordinary s.e.xual processes. Primordial instinct at work, Reith surmised. But how in good conscience could he turn her loose on the surface in such a condition of innocence? On the other hand the prospect of explaining human biology to Zap 210 was not a comfortable one.

Zap 210 herself never seemed to become bored with the pa.s.sage of time; she slept or sat looking off into the darkness as if she watched pa.s.sing vistas of great fascination. Vexed with her self-sufficiency, Reith would occasionally join her, taking no notice of her slight shift of fastidious withdrawal. Conversation with Zap 210 was never exhilarating. She had unalterable preconceptions regarding the surface: she feared the sky, the wind, the s.p.a.ce of the horizons, the pale brown sunlight. Her antic.i.p.ationswere melancholy: she foresaw death under the club of a yelling barbarian.

Reith tried to modify her views but encountered distrust.

"Do you think that we are ignorant of the surface?" she asked in calm scorn. "The zuzhma kastchai know more than anyone; they know everything. Knowledge is their existence. They are the brain-life of Tschai; Tschai is body and bones to the zuzhma kastchai."

"And the Pnumekin: how do they fit into the picture?"

"The 'persons'? Long ago the zuzhma kastchai gave refuge to certain men from the surface, with some females and some mother-women. The 'persons' proved their diligence by polishing stones and perfecting crystals.

The zuzhma kastchai provided peace, and so it has been, for all the ages."

"And where did men come from originally, do you know this?"

Zap 210 was uninterested. "From the ghian, where else?"

"Do they teach you of the sun and the stars and the other worlds of s.p.a.ce?"

"They teach what we most want to learn, which is decorum and good conduct." She heaved a small sigh. "That is all behind me and gone; how the others would marvel at me now!"

So far as Reith could comprehend, Zap 210's princ.i.p.al emotion appeared to be for her own indecorous conduct.

The barge moved on. Blue glimmer appeared ahead, waxed to become a glare and pa.s.s overhead, with a new blue glimmer far in the distance. Reith became stale and restless. Darkness was almost complete, relieved only by a vague glow from the bow ap.r.o.n forward. The feminine voice of Zap 210, herself only a blur, began to work upon his imagination; certain of her mannerisms took on the semblance of erotic provocations. Only by conscious rational effort could he maintain his impersonality. How, he would ask himself, could she provoke or tease when she was totally unaware of the male-female relationship? Any urgings from her subconscious must seem a peculiar perversion, the most exaggerated form of "boisterous conduct." He remembered the vitality of her body when she had clung to him in the water; he thought of the look of her soaked body; he began to wonder if his instincts might not be more accurate than his reason. Zap 210, if she felt anything other than glumness and foreboding, gave no evidence, except a somewhat greater willingness to talk. For hours she spoke in a low monotone, of everything she knew. She had lived a remarkably drab life, thought Reith, without experience of gaiety, excitement, frivolity. He wondered as to the content of her imaginings, but of this she said nothing. She recognized differences in the personalities of her fellows: subtle variations of decorum and discretion which to her a.s.sumed the same significance as the more vehement personality traits of the surface. She was aware of biological differences between male and female, but apparently had never wondered as to their justification. Allvery strange, mused Reith. The Shelters would seem to be an incubator for a whole congeries of neuroses. Reith dared venture no inquiries; whenever the conversation skirted such matters, she became instantly taciturn. Had the Pnume bred s.e.x drive out of the Pnumekin? Did they administer depressants, drugs, hormones, to eliminate a troublesome tendency to over-reproduce? Reith asked a few cautious questions, to which Zap 210 gave such irrelevant and unapposite replies that Reith was sure she didn't know what he was talking about. From time to time, Zap 210 admitted, certain persons found the Shelters too staid; they were sent up to the surface, into the glare, the blowing winds, the empty nights with all the universe exposed, and never allowed to return below. "I wonder that I am not more fearful," she said. "Is it possible that I have always had Gzhindra tendencies? I have heard that so much s.p.a.ce creates a distraction; I do not wish to be so affected."

"We're not on the surface yet," said Reith, to which Zap 210 gave a faint shrug, as if the matter were of no great importance.

Regarding the reproductive mechanisms of the Pnume she had no sure knowledge; she was uncertain whether or not the Pnume regarded the matter as secret, though she suspected as much. As to the relative number of Pnume and Pnumekin she was also uncertain. "There are probably more zuzhma kastchai. But many are never seen; they keep to the Deep Places, where the precious things are kept."

"What precious things?"

Again Zap 210 was vague. "The history of Tschai goes back beyond thought; just so far back go the records. The zuzhma kastchai are meticulous; they know everything that has ever happened. They consider Tschai to be a great conservatory, where every item, every tree, every rock is a cherished curio. Now there are off-world folk on the ghian: three different sorts, who have come to leave their artifacts."

"Three?"

"The Dirdir, the Chasch, the w.a.n.kh."

"What of men?"

"'Men'?" Her voice took on a dubious tone. "I don't know. Perhaps men too are off-world. If so, four peoples sojourn in Tschai. But this has happened before; many times have strange folk come down to Old Tschai.

The zuzhma kastchai neither welcome nor repel; they observe, they watch.

They expand their collections; they fill the museums of Foreverness; they compile their archives."

Reith began to see the Pnume in a new light. It seemed that they regarded the surface of Tschai as a vast theater, on which wonderful millennium-long dramas were played out: the Old Chasch-Blue Chasch wars; the Dirdir invasion, followed by the w.a.n.kh counter-invasion; the various campaigns, battles, routs, and exterminations; the building ofcities, the subsidence of ruins, the coming and going of peoples-all of which explained the acquiescence of the Pnume to the presence of alien races: from the Pnume point of view, they embellished the history of Tschai. As for Zap 210 herself, Reith asked if she had the same regard for Tschai. The girl made one of her small apathetic gestures: no, it meant nothing; she cared little one way or the other. Reith had a sudden insight into the processes of her psyche. Life for Zap 210 was a somewhat insipid experience to be tolerated. Fear was reserved for the unfamiliar; joy was beyond conjecture. He saw his own personality as it must appear to her: abrupt, brutal, crafty, harsh and unpredictable, in whom the worst excesses of boisterous conduct must always be feared ... A sad creature, thought Reith, inoffensive and colorless. Still, remembering the feel of her clinging to his neck, he wondered. Still waters ran deep. In the dark, with nothing to occupy his mind, imaginings came to stimulate him and arouse his fervor, whereupon Zap 210, somehow sensing his turmoil, moved uneasily off into the shadows, leaving Reith sourly amused by the situation. What could be going on in her mind?

Reith invented a new game. He tried to amuse her. He invented grotesque incidents, extravagant situations, but Zap 210 was the fairy-tale princess who could not laugh. Her single pleasure, insofar as Reith could detect, was the sweet-salt wafer which served as a relish to the otherwise bland food; unfortunately, the supply of these delicacies was quickly exhausted, a day or two after they had boarded the barge. Zap 210 was taken aback by the deficiency. "There is always diko in our diet-always!

Someone has made a foolish mistake!"

Reith had never seen her quite so emphatic. She became morose, then listless, and refused to eat anything whatever. Then she became nervous and irritable, and Reith wondered if perhaps the diko contained a habit- forming drug to arouse so p.r.o.nounced a craving.

For a period which might have been three or four days she spoke almost not at all, and kept as far from Reith as was practicable, as if she held Reith responsible for her deprivation, which was actually the case, reflected Reith. Had he not blundered rudely into her cool gray existence, she would be conducting her ordinary routine, nibbling diko whenever she was of a mind. Her sulkiness waned; she became almost talkative; she seemed to want rea.s.surance, or attention, or-could it be--affection. So it appeared to Reith, who found the situation as absurd as any he had known.

On and on through the dark moved the barge, from blue light to blue light to blue light. They pa.s.sed along a chain of underground lakes, through still caverns draped with stalact.i.tes, then for a long period, perhaps three days-along a precisely straight bore, with the blue lights s.p.a.ced ten miles apart. The bore gave into another set of caverns, where they once again saw a few lonesome docks: islands of dim yellow lights.Then once again the barge rode a straight ca.n.a.l. The voyage was approaching its end-the feeling was in the air. The crew moved with a somewhat less deliberate gait, and the pa.s.sengers on the starboard side went to stand on the forward ap.r.o.n. Zap 210, returning from the pantry with food, announced in a dolorous mutter: "We have almost come to Bazhan-Gahai."

"And where is this?"

"At the far side of the Area. We have come a long way." She added in a soft voice, "It has been a peaceful time."

Reith thought that she spoke with regret. "Is this place near the surface?"

"It is a trade center for goods from the Stang Islands and Hedaijha."

Reith was surprised. "We are far to the north."

"Yes. But the zuzhma kastchai may be waiting for us."

Reith looked anxiously ahead, at the far blue guide-light. "Why should they be?"

"I don't know. Perhaps they won't."

Blue lights, one after the other: Reith saw them pa.s.s with growing tension. He became tired, and slept; when he awoke, Zap 210 pointed ahead. "Bazhan-Gahai."

Reith rose to his feet. Ahead the gloom had lightened; the water showed a far luminous reflection. With dramatic majesty the tunnel widened; the barge moved forward, ponderous as fate. The cloaked shapes at the bow stood in silhouette against a great golden s.p.a.ce. Reith felt a lifting of the spirit, a mysterious exaltation. The voyage which had started in cold and misery was at its end. The sides of the tunnel-fluted b.u.t.tresses of raw rock- began to be visible, illuminated on one side, in black shadow on the other.

The golden light was a blur; beyond, across calm water, white crags rose to a great height. Zap 210 came slowly forward, to stare into the light with a rapt expression. Reith had almost forgotten what she looked like. The thin face, the pallor, the fragile bones of jaw and forehead, the straight nose and pale mouth were as he recalled; additionally he saw an expression to which he could put no name: sadness, melancholy, haunted foreboding. She felt his gaze and looked at him. Reith wondered what she saw.

The pa.s.sage opened and widened. A lake lay ahead, long and twisting.

The barge proceeded along vistas of uncanny beauty. Small islands broke the black surface; great gnarled columns of white and gray rose to the vaulted ceiling far above. Half a mile ahead, under a beetling overhang, a dock became visible. From an unseen opening a shaft of golden light slanted into the cavern.

Reith could hardly speak for emotion. "Sunlight!" he finally croaked.

The barge eased forward, toward the dock. Reith searched the cavern walls, trying to trace out a route to the gap. Zap 210 said in a soft voice, "You will attract attention."Reith moved back against the bales, and again studied the side of the cavern. He pointed. "A trail leads up to the gap."

"Of course."

Reith traced the trail along the wall. It seemed to terminate at the dock, now only a quarter of a mile distant. Reith noticed several shapes in black cloaks: Pnume or Pnumekin, he could not be sure. They stood waiting in what he considered sinister att.i.tudes; he became highly uneasy.

Going to the stern of the barge, Reith looked right and left. He returned to Zap 210. "In a minute or so we'll pa.s.s close to that island. That's where we better leave the barge. I don't care to land at that dock."

Zap 210 gave a fatalistic shrug. They went to the stern of the barge. The island, a twisted k.n.o.b of limestone, came abeam. Reith said, "Lower yourself into the water. Don't kick or flounder; I'll keep you afloat."

She gave him one unreadable side-glance and did as he bid. Holding the blue leather portfolio high in one hand he slid into the water beside her.

The barge moved away, toward whoever or whatever waited on the dock.

"Put your hands on my shoulders," said Reith. "Hold your face just above the water."

The ground rose under their feet; they clambered up on the island. The barge had almost reached the dock. The black shapes came forward. By their gait Reith knew them for Pnume.

From the island they waded to the sh.o.r.e, keeping to areas of shadow, where they were invisible to those on the dock, or so Reith hoped. A hundred feet above ran the trail to the gap. Reith made a careful reconnaissance, and they started to climb, scrambling over detritus, clinging to k.n.o.bs of agate, crawling over humps and b.u.t.tresses. A mournful hooting sound drifted across the water. Zap 210 became rigid.

"What does that mean?" Reith asked in a hushed voice.

"It must be a summons, or a call ... like nothing I have heard in Pagaz."

They continued up the slope, sodden cloaks clinging to their bodies, and at last heaved themselves up on the trail. Reith looked ahead and back; no living creature could be seen. The gap into the outer world was only fifty yards distant. Once again the hooting sounded, conveying a mournful urgency.

Panting, stumbling, they ran up the trail. The gap opened before them; they saw the golden-gray sky of Tschai, where a tumbled group of black clouds floated. He took a last look down the trail. With the light of outdoors in his face, with tears blurring his vision, he could distinguish only shadows and dim rockshapes. The underground was again a world remote and unknown. He took Zap 210's hand, pulled her out into the open. Slowly she stepped forward and looked across the surface. They stood halfway up the slope of a rocky hill overlooking a wide valley. In the distance spread a calm gray surface: the sea.Reith took a final look over his shoulder at the gap, and started down the hill. Zap 210, with a dubious glance toward the sun, followed. Reith halted.

He removed the hated black hat and sailed it off over the rocks. Then he took Zap 210's hat and did the same despite her startled protest.

CHAPTER FIVE.

FOR REITH THE walk down the wide valley in the brown-gold light of afternoon was euphoric. He felt light-headed; his torpor had vanished; he felt strong and agile and full of hope; he even felt a new and tolerant affection for Zap 210. An odd wry creature, he thought, watching her surrept.i.tiously, and pale as a ghost. She clearly felt uneasy in this sudden wilderness of s.p.a.ce. Her gaze moved from the sky, along the sweep of hills to either side, out to the horizon of what Reith had decided must be the First Sea.

They reached the floor of the valley. A sluggish stream wandered between banks of dark red reeds. Nearby grew pilgrim plant, the pods of which formed the indispensable staple food of Tschai. Zap 210 looked at the gray-green pods skeptically, failing to recognize the shriveled dry yellow tablets imported into the Shelters. She ate with fatalistic disinterest.

Reith saw her looking back the way they had come, somewhat wistfully, he thought. "Do you miss the Shelters?" he asked.

Zap 210 considered her reply. "I am afraid. We can be seen from all directions. Perhaps the zuzhma kastchai watch us from the gap. They may send night-hounds after us."

Reith looked up toward the gap: a shadow, almost invisible from where they sat. He could detect no evidence of scrutiny; they seemed alone in the open valley. But he could not be sure. Eyes could be watching from the gap; the black cloaks made them conspicuous. He looked toward Zap 210.

Almost certainly she would refuse to remove the garment ... Reith rose to his feet. "It's growing late; perhaps we can find a village along the sh.o.r.e."

Two miles downstream the river spread wide to become a swamp. Along the opposite sh.o.r.e grew a dense forest of enormous dyans, the trunks on the periphery slanting somewhat outward. Reith had seen such a forest before; it was, so he suspected, a sacred grove of the Khors, a truculent folk living along the south sh.o.r.e of the First Sea.

The presence of the sacred grove, if such it was, gave Reith pause. An encounter with the Khors might immediately validate Zap 210's fears regarding the ghaun, and the unpleasant habits of those who lived there.

At the moment there were no Khors in sight. Proceeding along the verge of the swamp they came out on a knoll overlooking a hundred yards of mud flat, with the sluggish First Sea beyond. Far to right and left were crumbling gray headlands, almost lost in the afternoon murk. Somewhere to the southeast, perhaps not too far, must lie the Carabas, where men sought sequins and where the Dirdir came to hunt.Reith looked up and down the coast, trying to locate himself by sheer instinct. Zap 210 stared glumly off to sea, wondering what the future held.

A mile or so along the sh.o.r.e to the southeast Reith noticed the crazy stilts of a pier extending across the mud flats, out into the sea; at the end half a dozen boats were moored. A swelling of ground beyond the swamp concealed the village which must lie at the head of the pier.

The Khors, while not automatically hostile, lived by a complicated etiquette, transgressions of which were not tolerated. A stranger's ignorance received no sympathy; the rules were explicit. A visit with the Khors thus became a chancy occasion.

"I don't dare risk the Khors," said Reith. He turned to look back over the desolate hills. "Sivishe is a long way south. We'll have to make for Cape Braise. If we get there we can take pa.s.sage by ship down the west coast, although at the moment I don't know what we'll use for money."

Zap 210 looked at him in slack-mouthed surprise. "You want me to come with you?"

So here was the explanation for her melancholy inspection of the landscape, thought Reith. He asked, "Did you have other plans?"

She pursed her lips sullenly. "I thought that you would want to go your way alone."

"And leave you by yourself? You might not fare too well."
