Pat laughed at the Americanism. "So this: From their form and structure-six limbs, three eyes, and all-it"s plain that the trioptes are related to ordinary native Hotlanders. There-fore I conclude that they"re recent arrivals on the dark side; that they didn"t evolve here, but were driven here quite lately, geologically speaking. Or geologically isn"t quite the word, be-cause gear means earth. Venusologically speaking, I should say."
"You shouldn"t say. You"re subst.i.tuting a Latin root for a Greek one. What you mean is aphrodisiologically speaking."
She chuckled again. "What I mean, and should have said right away to avoid argument, is paleaeontologically speaking, which is better English. Anyway, I mean that trioptes haven"t existed on the dark side for more than twenty to fifty thousand Earth years, or maybe less, because what do we know about the speed of evolution on Venus? Perhaps it"s faster than on the Earth; maybe a triops could adapt itself to night life in five thousand."
"I"ve seen college students adapt themselves to night life in one semester!" He grinned.
She ignored this. "And therefore," she proceeded, "I argue that there must have been life here before triops arrived, since it must have found something to eat when it got here or it couldn"t have survived.
And since my examination showed that it"s partly a carnivorous feeder, there must have been not only life here, but animal life. And that"s as far as pure reason can carry the argument."
"So you can"t guess what sort of animal life. Intelligent, perhaps?"
"I don"t know. It might be. But in spite of the way you Yankees worship intelligence, biologically it"s unimportant. It hasn"t even much survival value."
"What? How can you say that, Pat? What except human intelligence has given man the supremacy of the Earth-and of Venus, too, for that matter?"
"But has man the supremacy of the Earth? Look here, Ham, here"s what I mean about intelligence. A gorilla has a far better brain than a turtle, hasn"t it? And yet which is the more successful-the gorilla, which is rare and confined only to a small region in Africa, or the turtle, which is common everywhere from the arctic to the antarctic? And as for man -well, if you had microscopic eyes, and could see every Iiving thing on the Earth, you"d decide that man was just a rare specimen, and that the planet was really a nematode world-that is, a worm world-because the nematodes far outnumber all the other forms of life put together."
"But that isn"t supremacy, Pat."
"I didn"t say it was. I merely said that intelligence hasn"t much survival value. If it has, why are the insects that have no intelligence, but just instinct, giving the human race such a battle? Men have better brains than corn borers, boll weevils, fruit flies, j.a.panese beetles, gypsy moths, and all the other pests, and yet they match our intelligence with just one weapon-their enormous fecundity. Do you realize that every time a child is born, until it"s balanced by a death, it can be fed in only one way? And that way is by taking the food away from the child"s own weight of insects."
"All that sounds reasonable enough, but what"s it got to do with intelligence on the dark side of Venus?"
"I don"t know," replied Pat, and her voice took on a queer tinge of nervousness. "I just mean- Look at it this way, Ham. A lizard is more intelligent than a fish, but not enough to give it any advantage. Then why did the lizard and its descendants keep on developing intelligence? Why-unless all life tends to become intelligent in time? And if that"s true, then there may be intelligence even here-strange, alien, incomprehen-sible intelligence."
She shivered in the dark against him. "Never mind," she said in suddenly altered tones. "It"s probably just fancy. The world out there is so weird, so unearthly- I"m tired, Ham. It"s been a long day."
He followed her down into the body of the rocket. As the lights flicked on the strange landscape beyond the ports was blotted out, he saw only Pat, very lovely in the scanty costume of the Cool Country.
"Tomorrow, then," he said. "We"ve food for three weeks."Tomorrow, of course, meant only time and not daylight.
They rose to the same darkness that had always blanketed the sunless half of Venus, with the same eternal sunset green on the horizon at the barrier. But Pat was in better humor, and went eagerly about the preparations for their first venture into the open. She brought out the parkas of inch-thick wool sheathed in rubber, and Ham, in his capacity as engineer, care-fully inspected the hoods, each with its crown of powerful lamps.
These were primarily for vision, of course, but they had another purpose. It was known that the incredibly fierce trioptes could not face light, and thus, by using all four beams in the helmet, one could move, surrounded by a pro-tective aura. But that did not prevent both of them from in-cluding in their equipment two blunt blue automatics and a pair of the terrifically destructive flame-pistols. And Pat carried a bag at her belt, into which she proposed to drop specimens of any dark-side flora she encountered, and fauna, too, if it proved small and harmless enough.
They grinned at each other through their masks.
"Makes you look fat," observed Ham maliciously, and enjoyed her sniff of annoyance.
She turned, threw open the door, and stamped into the open.
It was different from looking out through a port. Then the scene had some of the unreality and all of the immobility and silence of a picture, but now it was actually around them, and the cold breath and mournful voice of the under-wind proved definitely enough that the world was real. For a moment they stood in the circlet of light from the rocket ports, staring awe-struck at the horizon where the unbeliev-able peaks of the Greater Eternities towered black against the false sunset.
Nearer, for as far as vision reached through that sunless, moonless, starless region, was a desolate tumbled plain where peaks, minarets, spires, and ridges of ice and stone rose in indescribable and fantastic shapes, carved by the wild artistry of the underwind.
Ham slipped a padded arm around Pat, and was surprised to feel her shiver. "Cold?" he asked, glancing at the dial thermometer on his wrist. "It"s only thirty-six below."
"I"m not cold," replied Pat. "It"s the scenery; that"s all."
She moved away. "I wonder what keeps the place as warm as it is. Without sunlight you"d think-"
"Then you"d be wrong," cut in Ham. "Any engineer knows that -gases diffuse. The upper winds are going by just five or six miles over our heads, and they naturally carry a lot of heat from the desert beyond the twilight zone. There"s some dif-fusion of the warm air into the cold, and then, besides, as the warm winds cool, they tend to sink. And what"s more, the contour of the country has a lot to do with it."
He paused. "Say," he went on reflectively, "I shouldn"t be surprised if we found sections near the Eternities where there was a down draft, where the upper winds slid right along the slope and gave certain places a fairly bearable climate."
He followed Pat as she poked around the boulders near the edge of the circle of light from the rocket.
"Ha!" she exclaimed. "There it is, Ham! There"s our speci-men of dark-side plant life."
She bent over a gray bulbous ma.s.s. "Lichenous or fungoid," she continued. "No leaves, of course; leaves are only useful in sunlight. No chlorophyl for the same reason. A very primitive, very simple plant, and yet-in some ways-not simple at all. Look, Ham-a highly developed circulatory system!"
He leaned closer, and in the dim yellow light from the ports he saw the fine tracery of veins she indicated.
"That," she proceeded, "would indicate a sort of heart and-I wonder!" Abruptly she thrust her dial thermometer against the fleshy ma.s.s, held it there a moment, and then peered at it. "Yes! Look how the needle"s moved, Ham. It"s warm! A warm-blooded plant. And when you think of it, it"s only natural, because that"s the one sort of plant that could live in a region forever below freezing. Life must be lived in liquid water."
She tugged at the thing, and with a sullen plump it came free, and dark driblets of liquid welled out of the torn root.
"Ugh!" exclaimed Ham. "What a disgusting thing! "And tore the bleeding mandragore," eh? Only they were supposed to scream when you uprooted them."
He paused. A low, pulsing, wailing whimper came out of the quivering ma.s.s of pulp, and he turned astartled gaze on Pat. "Ugh!" he grunted again. "Disgusting!"
"Disgusting? Why, it"s a beautiful organism! It"s adapted perfectly to its environment.
"Well, Fm glad I"m an engineer," he growled, watching Pat as she opened the rocket"s door and laid the thing on a square of rubber within. "Come on. Let"s look around."
Pat closed the door and followed him away from the roc-ket. Instantly the night folded in around them like a black mist, and it was only by glancing back at the lighted ports that Pat could convince herself that they stood in a real world.
"Should we light our helmet lamps?" asked Ham. "We"d better, I suppose, or risk a fall."
Before either could move farther, a sound struck through the moaning of the underwind, a wild, fierce, unearthly shrieking like laughter in h.e.l.l, hoots and howls and mirthless chuckling noises.
"It"s triopts!" gasped Pat, forgetting plurals and grammar alike.
She was frightened; ordinarily she was as courageous as Ham, and rather more reckless and daring, but those uncanny shrieks brought back the moments of torment when they had been trapped in the canyon in the Mountains of Eternity. She was badly frightened and fumbled frantically and ineffectually at light switch and revolver.
Just as half a dozen stones hummed fast as bullets around them, and one crashed painfully on Ham"s arm, he flicked on his lights. Four beams shot in a long cross on the glittering peaks, and the wild laughter rose in a crescendo of pain. He had a momentary glimpse of shadowy figures flinging them-selves from pinnacle and ridge, flitting specterlike into the darkness, and then silence.
"O-o-oh!" murmured Pat. "I-was scared, Ham." She hud-dled against him, then continued more strongly: "But there"s proof. Triops noctivians actually is a night-side creature, and those in the mountains are outposts or fragments that"ve wandered into the sunless chasms."
Far off sounded the hooting laughter. "I wonder," mused Ham, "if that noise of theirs is in the nature of a language."
"Very probably. After all, the Hotland natives are intel-ligent, and these creatures are a related species. Besides they throw stones, and they know the use of those smothering pods they showered on us in the canyon-which, by the way, must be the fruit of some night-side plant. The trioptes are doubt-less intelligent in a fierce, bloodthirsty, barbaric fashion, but the beasts are so unapproachable that I doubt if human beings ever learn much of their minds or language."
Ham agreed emphatically, the more so as a viciously cast rock suddenly chipped glittering particles from an icy spire a dozen paces away. He twisted his head, sending the beams of his helmet lamps angling over the plain, and a single shrill cachinnation drifted out of the dark.
"Thank Heaven the lights keep "em fairly out of range," he muttered. "These are pleasant little subjects of His Maj-esty, * aren"t they? G.o.d save the king if he had many more like "em!"
But Pat was again engaged in her search for specimens. She had, switched on her lamps now, and scrambled agilely in and out among the fantasic monuments of that bizarre plain. Ham followed her, watching as she wrenched up bleeding and whimpering vegetation. She found a dozen varieties, and one little wriggling cigar-shaped creature that she gazed at in per-plexity, quite unable to determine whether it was plant, ani-mal or neither. And at last her specimen bag was completely filled, and they turned back over the plain toward the rocket, whose ports gleamed afar like a row of staring eyes.
But a shock awaited them as they opened the door to enter. Both of them started back at the gust of warm, stuffy, putrid, and unbreathable air that gushed into their faces with an odor of carrion.
"What-" gasped Ham, and then laughed. "Your mandra-gore!" He chuckled. "Look at it!"
The plant she had placed within was a ma.s.s of decayed corruption. In the warmth of the interior it had decomposed rapidly and completely and was now but a semiliquid heap on the rubber mat. She pulled it through the entrance and flung mat and all away.
They clambered into an interior still reeking, and Ham set a ventilator spinning. The air that came in was cold, of course, but pure with the breath of the underwind, sterile and dustless from its sweep across five thousand miles of frozen oceans *They were on British territory, being in the lat.i.tude of Ven.o.ble. The International Congress at Lislehad in 2020 appor-tioned the dark-side rights by giving to each nation owning Venu-sian possessions a wedge extending from the twilight zone to a point on the planet directly opposite the Sun in mid-autumn.and mountains. He swung the door closed, set a heater going, and dropped his visor to grin at Pat.
"So that"s your beautiful organism!" he chuckled.
"It was. It was a beautiful organism, Ham. You can"t blame it because we exposed it to temperatures it was never sup-posed to encounter." She sighed and slung her specimen pouch to the table. "I"ll have to prepare these at once, I suppose, since they don"t keep."
Ham grunted and set about the preparation of a meal, working with the expert touch of a true Hotlander. He glanced at Pat as she bent over her specimens, injecting the bichlorid solution.
"Do you suppose," he asked, "that the triops is the highest form of life on the dark side?"
"Beyond doubt," replied Pat. "If any higher form existed, it would long ago have exterminated those fierce devils." But she was utterly wrong.
Within the span of four days they had exhausted the possibilities of the tumbled plain around the rocket. Pat had acc.u.mulated a variegated group of specimens, and Ham had taken an endless series of observations on temperature, on magnetic variations, on the direction and velocity of the Underwind.
So they moved their base, and the rocket flared into flight southward, toward the region where, presumably, the vast and mysterious Mountains of Eternity towered across the ice barrier into the dusky world of the night side. They flew slowly, throttling the reaction motors to a bare fifty miles an hour, for they were flying through night, depending on the beam of the forward light to warn against looming peaks.
Twice they halted, and each time a day or two sufficed to indicate that the region was similar to that of their first base. The same veined and bulbous plants, the same eternal under-wind, the same laughter from bloodthirsty trioptic throats.
But on the third occasion, there was a difference. They came to rest on a wild and bleak plateau among the foothills of the Greater Eternities. Far away to the westward, half the horizon still glowed green with the false sunset, but the whole span south of the due-west point was black, hidden from view by the vast ramparts of the range that soared twenty-five miles above them into the black heavens. The mountains were invisible, of course, in that region of endless night, but the two in the rocket felt the colossal nearness of those incredible peaks.
And there was another way in which the mighty presence of the Mountains of Eternity affected them.
The region was warm-not warm by the standards of the twilight zone, but much warmer than the plain below. Their thermometers showed zero on one side of the rocket, five above on the other. The vast peaks, ascending into the level of the upper winds, set up eddies and stray currents that brought warm air down to temper the cold breath of the underwind.
Ham stared gloomily over the plateau visible in the lights. "I don"t like it," he grunted. "I never did like these mountains, not since you made a fool of yourself by trying to cross "em back in the Cool Country."
"A fool!" echoed Pat. "Who named these mountains? Who crossed them? Who discovered them? My father, that"s who!"
"And so you thought you inherited "em," he retorted, "and that all you had to do was to whistle and they"d lie down and play dead, and Madman"s Pa.s.s would turn into a park walk. With the result that you"d now be a heap of clean-picked bones in a canyon if I hadn"t been around to carry you out of it."
"Oh, you"re just a timid Yankee!" she snapped. "I"m going outside to have a look." She pulled on her parka and stepped to the door, and there paused. "Aren"t you-aren"t you coming, too?" she asked hesitantly.
He grinned. "Sure! I just wanted to hear you ask." He slipped into his own outdoor garb and followed.
There was a difference here. Outwardly the plateau pre-sented the same bleak wilderness of ice and stone that they had found on the plain below. There were wind-eroded pinnacles of the utmost fantasy of form, and the wild land-scape that glittered in the beams from their helmet lamps was the same bizarreterrain that they had first encountered.
But the cold was less bitter here; strangely, increasing alt.i.tude on this curious planet brought warmth instead of cold, as on the Earth, because it raised one closer to the region of the upper winds, and here in the Mountains of Eternity the underwind howled less persistently, broken into gusts by the mighty peaks.
And the vegetation was less spa.r.s.e. Everywhere were theveined and bulbous ma.s.ses, and Ham had to tread carefully lest he repeat the unpleasant experience of stepping on one and hearing its moaning whimper of pain. Pat had no such scruples, insisting that the whimper was but a tropism; that the specimens she pulled up and dissected felt no more pain than an apple that was eaten; and that, anyway, it was a biologist"s business to be a biologist.
Somewhere off among the peaks shrilled the mocking laughter of a triops, and in the shifting shadows at the extremities of their beams, Ham imagined more than once that he saw the forms of these demons of the dark. If there they were, however, the light kept them at a safe distance, for no stones hummed past.
Yet it was a queer sensation to walk thus in the center of a moving circle of light; he felt continually as if just be-yond the boundary of visibility lurked Heaven only knew what weird and incredible creatures, though reason argued that such monsters couldn"t have remained undetected.
Ahead of them their beams glistened on an icy rampart, a bank or cliff that stretched right and left across their course.
Pat gestured suddenly toward it. "Look there!" she ex-claimed, holding her light steady. "Caves in the ice-burrows, rather. See?"
He saw-little black openings as large, perhaps, as a manhole cover, a whole row of them at the base of the ice rampart. Something black skittered laughing up the gla.s.sy slope and away-a triops. Were these the dens of the beasts? He squinted sharply.
"Something"s there!" he muttered to Pat. "Look! Half the openings have something in front of them-or are those just rocks to block the entrance?"
Cautiously, revolvers in hand, they advanced. There was no more motion, but in the growing intensity of the beams, the objects were less and less rocklike, and at last they could make out the veinings and fleshy bulbousness of life.
At least the creatures were a new variety. Now Ham could distinguish a row of eyelike spots, and now a multiplicity of legs beneath them. The things were like inverted bushel baskets, about the size and contour, veined, flabby, and featureless save for a complete circle of eye spots. And now he could even see the semitransparent lids that closed, apparently, to shield the eyes from the pain of their lights.
They were barely a dozen feet from one of the creatures. Pat, after a moment of hesitation, moved directly before the motionless mystery.
"Well!" she said. "Here"s a new one, Ham, h.e.l.lo, old fella!"
An instant later both of them were frozen in utter con-sternation, completely overwhelmed by bewilderment, amaze-ment, and confusion. Issuing, it seemed, from a membrane at the top of the creature, came a clicking, high-pitched voice.
"h.e.l.lo, fella!" it said.
There was an appalled silence. Ham held his revolver, but had there been need, he couldn"t have used it, nor even re-membered it. He was paralyzed, stricken dumb.
But Pat found her voice. "It-isn"t real," she said faintly. "It"s a tropism. The thing just echoed whatever sounds strike it. Doesn"t it, Ham? Doesn"t it?"
"I-I--of course!" He was staring at the lidded eyes. "It must be. Listen!" He leaned forward and yelled, "h.e.l.lo!" directly at the creature. "It"ll answer."
It did. "It isn"t a tropism," it clicked in shrill but perfect English.
"That"s no echo!" gasped Pat. She backed away. "I"m scared," she whimpered, pulling at Ham"s arm.
"Come away-quick!"
He thrust her behind him. "I"m just a timid Yankee," he grunted, "but I"m going to cross-question this living phono graph until I find out what-or who-makes it tick." "No! No, Ham! I"m scared!""It doesn"t look dangerous," he observed.
"It isn"t dangerous," remarked the thing on the ice. Ham gulped, and Pat gave a horrified little moan.
"Who-who are you?" he faltered.
There was no answer. The lidded eyes stared steadily at him.
"What are you?" he tried again.
Again no reply.
"How do you know English?" he ventured.
