Her voice choked and she could not go on; but the eyes that were raised to his were luminous through the tears that filled them.

From the cabin beyond came a clash of levers, where Chet was preparing to open a port. And Harkness followed with unseeing eyes where the pilot waited that their commander might be the first to step forth upon an unknown globe—upon the surface of what men had called "The Dark Moon."

CHAPTER VI

Trapped

alter Harkness, piloting his ship to a slow, safe landing on a new world, had watched his instruments with care. He had seen the outer pressure build up to that of the air of Earth; the spectro-analyzer had shown nitrogen preponderating, with sufficient oxygen to support life. And, below him, a monstrous thing that flopped hurriedly away on leather wings had told him that life was there.

But what would that life be? This was the question uppermost in the minds of all three as they stepped forth—the first of Earth's people to ask the question and to find the answer.

Chet had gone to their stores. He strapped a belt about his waist, a belt banded with a row of detonite cartridges, and a pistol hung at his hip. He handed another to Harkness. But the pistol he offered Diane was refused.

"My many accomplishments," she laughed, "do not include that. I never could shoot—and besides I will not need to with both of you here." Her hand was resting confidently upon Chet's arm as they followed where Harkness led.

The heavy grass, standing waist-high in the little valley where their ship was at rest, stirred to ripples of vivid green as a light breeze touched it. Above, the sun shone warm upon this world of tropical growth. Harkness, listening in the utter silence for sounds that might mean danger, let his eyes follow up the rugged wall of rock that hemmed them in on two sides. It gleamed with metallic hues in the midday glare. He looked on to the sun above.
