Harbin remarked that, insofar as the fossil record had proven, Mars had never supported avian life, either bird or insect. The winged serpents of Martian legend he dismissed out of hand as being that—merely legend.
“Where d’you suppose all of this light is coming from?” muttered Brant. “Not from the sky. Seems to be from the surface—see how brilliant it is beyond those hills?”
“Yep. Well … let’s take a look,” suggested Harbin. “Only way to find out for sure. May be in the very air itself, chemical phosphorescence—”
Brant cut him off with an abrupt gesture. He opened his mouth to yell a warning, but it was already too late. Agila had broken off a dripping chunk of the soft underflesh of one of the huge toadstools and was gingerly nibbling on it. Harbin uttered an exclamation, but Brant stopped his protest with an easy shrug.
“We’ll soon find out if the stuff is bad to eat,” he grinned. “What the hell, we can do without that treacherous devil to watch.”
But he warned Suoli not to taste the stuff, and strolled near to take a look. It was yellow and soft, like spongecake, and dripping like a fresh honeycomb.
“How does it taste?” he inquired.
“Very good!” mumbled Agila around a cheekful. “A taste such as Agila has never before encountered.”
He was lapping the stuff up as fast as he could claw another handful out of the soft trunk, and it didn’t seem to be making him sick, so Brant cautiously tasted a crumb of it himself.
It was sweet as honey and as tangy as wine, the dripping fluid, and the meat bore a distinct flavor of applesauce.
Just then a call came from some little distance away. Brant turned to see that, while he had gone to check out Agila’s reaction to the fungus, Harbin had continued on to climb the gentle slope of the hills, hoping to discover the source of the illumination.
“Anything to see, Doc?” Brant called back.
For a moment, Harbin made no reply, staring raptly into the distance. Then he turned to beckon to Brant, and the expression on his face was one such as Brant had never before seen, save perhaps in religious paintings of prophets and saints caught up in ecstasy.
“You must see this, my boy … a miracle beyond belief.”
17 Beyond Belief
Leaving Zuarra, who was cautiously sampling the fleshy meat of the great fungus growths, Brant climbed the mossy slope of the hill to where Will Harbin stood awestruck, staring with wondering gaze into the luminosity.
And Brant stopped short, uttering a grant of amazement.
From a gemmy shore at the foot of the other side of the hill, for as far as the eye could reach, there stretched a shining sea.
The water was milky-white, quite opaque, and was clearly the source of the mysterious luminance, for the radiant fluid was like the essence of light itself, curdled into pearly fire.
“A … sea,” whispered Brant faintly. “Here at the bottom of the world … !”
“Yes. In fact, it is the Last Ocean,” said Will Harbin softly. “The last of all the mighty oceans of primal Mars, draining into this cavern and forgotten since the beginning of time itself … what a marvel. A miracle!”
They stood for a moment, staring in awe at the vast expanse of luminous waters, and Doc Harbin murmured something in low tones to himself, his expression bemused and wondering. Brant glanced at him inquiringly.
“More Dante?” Harbin flushed a. little, and grinned.
“No, a British poet this time—Coleridge.” And he repeated a few lines of the old poem.
” ‘… where Alph the sacred river ran Through caverns measureless to man, Down to a sunless sea . . “
Brant grunted, impressed. “You’d almost think he got a glimpse of this place, somehow,” he remarked.
“Maybe he did, in some uncanny way,” Harbin mused. “He said he wrote the poem in a dream, and, when awake, copied down as many lines as he could still remember.”
“What … makes it glow like that?” Brant wondered.
“Natural phosphorescence, maybe. Some luminous chemical. Even algae, just possibly. Or residual radiation,” murmured Doc Harbin. “Anyway, what a sight, Jim! Truly, like the old phrase has it, a ‘shining sea’ …”
After a time, he picked up the thread of conversation again. “When the planet began to dry up, and the surface cracked, most of the prehistoric oceans dispersed into the atmosphere. Mars has a low gravitational field, too weak to hang onto water molecules for long, unlike Earth.
“Remember those dustlands, where we met?” he went on. Brant nodded; he remembered them well. “The Argyre,” Harbin said. “Once the bottom of an ocean. Well, that narrow, deep chasm across it called the Erebus—one of those cracks in the planetary crust I was talking about. It would seem that not all of the oceanwater dispersed into the atmosphere to be lost forever … some, like this, must have leaked into vast caverns beneath the crust, through chasms like the Erebus. No other way to explain it!”
“Yeah, I see what you mean,” drawled Brant.
The three Martians had followed them to the hilltop by now, and stood as if struck by lightning, too paralyzed by astonishment to move, even to speak or cry out.
“Chasm or no chasm, when the old ocean seeped down through the crust, it must have picked up a lot of minerals along the way. It must have taken many centuries to happen. Which may explain the curious phenomenon of the luminescence. …”
“And maybe even the stone stair!” suggested Brant, surprised at his own sharpness. “There were people living up there on the continent we call Ogygis Regio in those days: I found Zuarra and Suoli in the ruins of one of their cities, remember.”
“I recall,” Doc said slowly.
“They were sea-kings, maybe. Like the Vikings of old. And they watched their ocean ebb year after year, generation utter generation. And cut a stairway down to what remained <>l their sea. Maybe they venerated it, had religious feelings about it … anyway, to hew those thousands of steps out of solid rock would sure require centuries of labor.”
Harbin cast him a strange glance. “I’m impressed, my hoy. You’ve a head on your shoulders. I think you have hit on the truth, strange as it sounds to us. But stranger things have happened, and for even less comprehensible reasons . . the building of the Egyptian pyramids, for example. The Great Wall of China. Built to keep the savage nomads away, but it was the descendants of those very nomads that completed the work, for their ancestors had conquered China by then, wall or no wall.”
After a while, they descended the hill to pace the narrow shore. Will Harbin squatted to examine the glittering sand that looked for all the world as if it was carpeted with jewels of every color and description—rubies, pearls, emeralds, topazes, yellow zircons, amethysts, opals, lumps of amber and jade, sapphires, even dull but lucent diamonds.
“Mineral deposits,” he decided, “not gems. The water must be incredibly rich in mineral salts. They would coagulate like this, coming together into lumps, forming pebbles by conglomeration, under the movement of the waves.”
Zuarra bent to pick one of these from the shore. It was smooth as glass, more oval than teardrop-shaped, and blazing with rich colors, brown, amber, gold, all streaked through with crimson. She exclaimed over the beauty of the thing.
