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 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.
