Astounding Stories of Super-Science April 1930 by Anthony Pelcher (reading e books .txt) 📗

In the mid-northern hemisphere upon the Earthward side of the Moon, the giant crater of Archimedes stood brooding in silent majesty. Grim, lofty walls, broken, pitted and scarred, rising precipitous to the upper circular rim. Night had just fallen. The sunlight clung to the crater-heights; it tinged with flame the jagged peaks of the Apennine Mountains which rose in tiers at the horizon; and it flung great inky shadows over the intervening lowlands.

Northward, the Mare Imbrium stretched mysterious and purple, its million rills and ridges and crater holes flattened by distance and the gathering darkness into a seeming level surface. The night slowly deepened. The dead-black vault of the sky blazed with its brilliant starry gems. The gibbous Earth hung high above the horizon, motionless, save for the invisible pendulum sway over the tiny arc, of its libration: widening to quadrature, casting upon the bleak naked Lunar landscape its mellow Earth-glow.

Slow, measured process, this coming of the Lunar night! For an Earth-day the sunset slowly faded on the Apennines; the poised Earth widened a little further—an Earth-day of time, with the Earth-disc visibly rotating, the faint tracery of its oceans and continents passing in slow, majestic review.

Another Earth-day interval. Then another. And another. Full night now enveloped Archimedes. Splotches of Earth-light and starlight sheen slowly shifted as the night advanced.

Between the great crater and the nearby mountains, the broken, pseudo-level lowlands lay wan in the Earth-light. A few hundred miles, as distance would be measured upon Earth. A million million rills were here. Valleys and ridges, ravines, sharp-walled canyons, cliffs and crags—tiny craters like pock-marks.

Naked, gray porous rock everywhere. This denuded landscape! Cracked and scarred and tumbled, as though some inexorable Titan torch had seared and crumbled and broken it, left it now congealed like a wind-lashed sea abruptly frozen into immobility.

Moonlight upon Earth so gently shines to make romantic a lover's smile! But the reality of the Lunar night is cold beyond human rationality. Cold and darkly silent. Grim desolation. Awesome. Majestic. A frowning majesty that even to the most intrepid human beholder is inconceivably forbidding.

And there were humans here now. On this tumbled plain, between Archimedes and the mountains, one small crater amid the million of its fellows was distinguished this night by the presence of humans. The Grantline camp! It huddled in the deepest purple shadows on the side of a bowl-like pit, a crudely circular orifice with a scant two miles across its rippling rim. There was faint light here to mark the presence of the living intruders. The blue-glow radiance of Morrell tube-lights under a spread of glassite.

The Grantline camp stood mid-way up one of the inner cliff-walls of the little crater. The broken, rock-strewn floor, two miles wide, lay five hundred feet below the camp. Behind it, the jagged precipitous cliff rose another five hundred to the heights of the[86] upper rim. A broad level shelf hung midway up the cliff, and upon it Grantline had built his little group of glassite dome shelters. Viewed from above there was the darkly purple crater floor, the upflung circular rim where the Earth-light tinged the spires and crags with yellow sheen; and on the shelf, like a huddled group of birds nests, Grantline's domes clung and gazed down upon the inner valley.

Intricate task, the building of these glassite shelters! There were three. The main one stood close at the brink of the ledge. A quadrangle of glassite walls, a hundred feet in length by half as wide, and a scant ten feet high to its flat-arched dome roof. Built for this purpose in Great-New York, Grantline had brought his aluminite girders and braces and the glassite panels in sections.

The air here on the Moon surface was negligible—a scant one five-thousandth of the atmospheric pressure at the sea-level on Earth. But within the glassite shelter, a normal Earth-pressure must be maintained. Rigidly braced double walls to withstand the explosive tendency, with no external pressure to counteract it. A tremendous necessity for mechanical equipment had burdened Grantline's small ship to its capacity. The chemistry of manufactured air, the pressure equalizers, renewers, respirators, the lighting and temperature-maintenance systems—all the mechanics of a space-flyer were here.

And within the glassite double walls, there was necessity for a constant circulation of the Erentz temperature insulating system.[D]

There was this main Grantline building, stretching low and rectangular along the front edge of the ledge. Within it were living rooms, messroom and kitchen. Fifty feet behind it, connected by a narrow passage of glassite, was a similar, though smaller structure. The mechanical control rooms, with their humming, vibrating mechanisms were here. And an instrument room with signaling apparatus, senders, receivers, mirror-grids and audiphones of several varieties; and an electro-telescope, small but modern, with dome overhead like a little Earth observatory.

From this instrument building, beside the connecting pedestrian passage, wire cables for light, and air-tubes and strings and bundles of instrument wires ran to the main structure—gray snakes[87] upon the porous, gray Lunar rock.

The third building seemed a lean-to banked against the cliff-wall, a slanting shed-wall of glassite fifty feet high and two hundred in length. Under it, for months Grantline's borers had dug into the cliff. Braced tunnels were here, penetrating back and downward into this vein of radio-active rock.

The work was over now. The borers had been dismantled and packed away. At one end of the cliff the mining equipment lay piled in a litter. There was a heap of discarded ore where Grantline had carted and dumped it after his first crude refining process had yielded it as waste. The ore-slag lay like gray powder-flakes strewn down the cliff. Tracks and ore-carts along the ledge stood discarded, mute evidence of the weeks and months of work these helmeted miners had undergone, struggling upon this airless, frowning world.

But now all that was finished. The radio-active ore was sufficiently concentrated. It lay—this treasure—in a seventy-foot pile behind the glassite lean-to, with a cage of wires over it and an insulation barrage guarding its Gamma rays from escaping to mark its presence.

The ore-shelter was dark; the other two buildings were lighted. And there were small lights mounted at intervals about the camp and along the edge of the ledge. A spider ladder, with tiny platforms some twenty feet one above the other, hung precariously to the cliff-face. It descended the five hundred feet to the crater floor; and, behind the camp, it mounted the jagged cliff-face to the upper rim-height, where a small observatory platform was placed.

Such was the outer aspect of the Grantline Treasure Camp near the beginning of this Lunar night, when, unbeknown to Grantline and his score of men, the Planetara with its brigands was approaching. The night was perhaps a sixth advanced. Full night. No breath of cloud to mar the brilliant starry heavens. The quadrant Earth hung poised like a giant mellow moon over Grantline's crater. A bright Earth, yet no air was here on this Lunar surface to spread its light. Only a glow, mingling with the spots of blue tube-light on the poles along the cliff, and the radiance from the lighted buildings.

The crater floor was dimly purple. Beyond the opposite upper rim, from the camp-height, the towering top of distant Archimedes was visible.

No evidence of movement showed about the silent camp. Then a pressure door in an end of the main building opened its tiny series of locks. A bent figure came out. The lock closed. The figure straightened and gazed about the camp. Grotesque, bloated semblance of a man! Helmeted, with rounded dome-hood suggestion of an ancient sea diver, yet goggled and trunked like a gas-masked fighter of the twentieth century war.

He stooped presently and disconnected metal weights which were upon his shoes.[E]

Then he stood erect again, and with giant strides bounded along the cliff. Fantastic figure in the blue-lit gloom! A child's dream of crags and rocks and strange lights with a single monstrous figure in seven-league boots.

He went the length of the ledge with his twenty-foot strides, inspected the lights, and made adjustments. Came back, and climbed with agile, bounding leaps up the spider ladder to the dome on the crater top. A light flashed on up there. Then it was extinguished.

The goggled, bloated figure came leaping down after a moment. Grantline's exterior watchman making his rounds. He came back to the main building. Fastened the weights on his[88] shoes. Signaled within.

The lock opened. The figure went inside.

It was early evening, after the dinner hour and before the time of sleep, according to the camp routine Grantline was maintaining. Nine P. M. of Earth Eastern-American time, recorded now upon his Earth chronometer. In the living room of the main building Johnny Grantline sat with a dozen of his men dispersed about the room, whiling away as best they could the lonesome hours.

"All as usual. This cursed Moon! When I get home—if ever I do get home—"

"Say your say, Wilks. But you'll spend your share of the gold-leaf and thank your constellations that you had your chance!"

"Let him alone! Come on, Wilks, take a hand here. This game is no good with three."

The man who had been outside flung his hissing helmet recklessly to the floor and unsealed his suit. "Here, get me
