Astounding Stories of Super-Science April 1930 Part 32

And Miko had seen it.

"Why George, how surprising! Away with that cloak!"

He seized her wrist, drew her forward, beyond the shaft of zed-light, into the brilliant light of the Moon. And ripped her cloak from her. The gentle curves of her woman's figure were so unmistakable!

And as Miko gazed at them, all his calm triumph swept away.

"Why, Anita!"

I heard Moa mutter: "So that is it?" A venomous flas.h.i.+ng look--a shaft from me to Anita and back again. "So that is it?"

"Why, _Anita_!"

Miko's great arms gathered her up as though she were a child. "So I have you back; from the dead delivered back to me!"

"Gregg!" Snap's warning, and his grip over my shoulders brought me a measure of sanity. I had tensed to spring. I stood quivering, and Moa thrust her weapon against my face. The helio mirrors were swaying again with another message from Grantline. But it came ignored by us all.

In the glare of moonlight by the forward window, Miko held Anita, his great hands pawing her with triumphant possessive caresses.

"So, little Anita, you are given back to me."

Against her futile struggles he held her.

Dear G.o.d, if only I had had the wit to have prevented this!

CHAPTER XX

_The Grantline Camp_

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 pa.s.sing 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 s.h.i.+fted 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 t.i.tan 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 s.h.i.+nes 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 gla.s.site.

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 upper rim. A broad level shelf hung midway up the cliff, and upon it Grantline had built his little group of gla.s.site 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 gla.s.site shelters! There were three. The main one stood close at the brink of the ledge. A quadrangle of gla.s.site 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 gla.s.site 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 gla.s.site 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 s.h.i.+p to its capacity. The chemistry of manufactured air, the pressure equalizers, renewers, respirators, the lighting and temperature-maintenance systems--all the mechanics of a s.p.a.ce-flyer were here.

And within the gla.s.site 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 pa.s.sage of gla.s.site, 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 pa.s.sage, wire cables for light, and air-tubes and strings and bundles of instrument wires ran to the main structure--gray snakes upon the porous, gray Lunar rock.

The third building seemed a lean-to banked against the cliff-wall, a slanting shed-wall of gla.s.site 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.

[D] An intricate system of insulation against extremes of temperature, developed by the Erentz Kinetic Energy Corporation in the twenty-first century. Within the hollow double sh.e.l.l of a shelter-wall, or an explorer's helmet-suit, or a s.p.a.ce-flyer's hull, an oscillating semi-vacuum current was maintained--an extremely rarified air, magnetically charged, and maintained in rapid oscillating motion. Across this field the outer cold, or heat, as the case might be, could penetrate only with slow radiation. This Erentz system gave the most perfect temperature insulation known in its day. Without it, interplanetary flight would have been impossible.

And it served a double purpose. Developed at first for temperature insulation only, the Erentz system surprisingly brought to light one of the most important discoveries made in the realm of physics of the century. It was found that any flas.h.i.+ng, oscillating current, whether electronic, or the semi-vacuum of rarified air--or even a thin sheet of whirling fluid--gave also a pressure-insulation. The kinetic energy of the rapid movement was found to absorb within itself the latent energy of the unequal pressure.

(The intricate postulates and mathematical formulae necessary to demonstrate the operation of the physical laws involved would be out of place here.)

The _Planetara_ was so equipped, against the explosive tendency of its inner air-pressures when flying in the near-vacuum of s.p.a.ce. In the case of Grantline's gla.s.site shelters, the latent energy of his room interior air pressure went largely into a kinetic energy which in practical effect resulted only in the slight acceleration of the vacuum current, and thus never reached the outer wall. The Erentz engineers claimed for their system a pressure absorption of 97.4%, leaving, in Grantline's case, only 2.6% of room pressure to be held by the building's aluminite bracers.

It may be interesting to note in this connection that without the Erentz system as a basis, the great sub-sea developments on Earth and Mars of the twenty-first century would also have been impossible. Equipped with a fluid circulation device of the Erentz principle within its double hull, the first submarine was able to penetrate the great ocean deeps, withstanding the tremendous ocean pressures at depths of four thousand fathoms.

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 gla.s.site 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.
