was a huddled blob with a long-barreled bullet-gun resting in a rock crevice as she peered out at the line of rocks behind which his leap had carried him. He was much nearer to her now; not over twenty feet. And he cautiously peered, more amazed than ever. The pearly, glowing sheen of the Saturn-light glistened on her skin. Her oval face, framed by her flowing black hair, was set and grim, but he could see that it was a beautiful face. "What the devil," Morgan muttered to himself. He had clipped his gun to his broad leather belt. Still grimly smiling, he picked up a huge chunk of the porous gray-black Titan rock and heaved it. The rock sailed over the girl; fell with a clatter behind her. It made her give another startled cry as she aimed toward the sound. And simultaneously, Morgan leaped again--with a bound that carried him back over the gully, and landed him almost at the girl's side. She screamed, tried to struggle to her feet, with the gun jerking around. But Morgan gripped the barrel. "Easy," he murmured. "Don't get excited; I won't hurt you." He thought that his tone, if perhaps not his words, would quiet her. And then she gasped, "You--you let me alone!" She spoke English! Morgan was beyond being amazed at anything now. He snatched the rusty old gun from her and tossed it away. She stood docile within his grip, terrified, but defiant. She was younger than he had thought, not over sixteen or seventeen probably. Her single, blue-gray garment, he could see now, was tattered, frayed. It had the look of a fabric fragile with age. It fell from her pink-white shoulders to her thighs. A crudely fashioned animal-skin belt girdled her slender waist. Leather thongs crossed her breast, modeling the dress, and her long black hair lay there in a tangle. Her feet were bare, with toughened soles from long walking on these jagged rocks."Let me alone," she was muttering. She stood swaying backward in his grip, her dark eyes watchful, alert. He could not miss now the wildness upon her, a weird mixture of savagery and civilization. She looked as though she were figuring only how she could kill him. "Well," he said, "I don't get this at all. What's your name?" "Nada," she gasped. "Nothing else? You speak English so you're from Earth. Now how in the devil--" She suddenly twitched away from him, but he caught her and again she stood panting.
