Beside them a sinuous form showed where a serpent of space was trying to match their speed. Harkness saw it twisting convulsively in the stratum of gas; it was falling, lifeless, beside them as they sped on and away. Here was something the beasts could not combat. He made a mental note of the fact, but his thoughts flashed again to what lay ahead. Every eye was held close to the lookouts that faced forward. The three were breathless, wordless; the hand of Harkness that held the tiny ball was all that moved. Ahead of them was their goal, the Dark Moon! And they were prepared for Stygian darkness and a land of perpetual night. The almost invisible gas-clouds thinned; there was a glow ahead that grew brilliant as they watched; and then, with a blinding suddenness that made them shield their eyes, there flashed before them a world of light. Each line of shore was marked distinctly there; the blue and violet of rippling seas were blended with unreal hues; there were mountains upthrust and, on the horizon, a range of volcanic peaks that poured forth flashing eruptions half-blanketed by invisible gas. "The Dark Moon!" gasped Harkness. He was spellbound with utter awe at the spectacle he beheld. This brilliant world a-gleam to its farthest horizon with golden, glorious sunlight, softly spread and diffused! This, _this!_ was the Dark Moon! * * * * * He turned to share with the others the delirium of ecstatic wonder too overpowering to be borne alone--turned, to find his happiness shot through with a pang of regret. He saw Chet and Diane. They had been standing together at a wide forward lookout; and now she was holding one hand of the pilot to her breast in an embrace of passionate joy. Unconscious, that gesture of delight at this climax of their perilous trip?--Harkness told himself that this was so. But he swung back to the helm of the ship. He glanced at instruments that again were registering; he saw the air-pressure indicator that told of oxygen and an atmosphere where men might live. He gauged his distance carefully, and prepared to land. The moment of depression could not last, for there was too much here to fill brain and eyes. What would they find? Was there life? His question was answered by an awkward body that flapped from beneath them on clumsy wings. He glimpsed a sinuous neck, a head that was all mouth and flabby pouch, and the mouth opened ludicrously in what was doubtless a cry of alarm. Then land, that took form and detail; a mountain whose curled top was like a frozen wave of stone. In a valley below it trees were growing. They swayed in a wind, and their branches reached upward and flowed and waved like seaweed on the ocean's floor. Green--vivid, glowing green!--and reds and purples that might be flowers and fruit. * * * * *
