She made a quick motion then, with both hands, as though she placed a cap upon the shining glory of her head, and I understood in an instant what she wished: the antenna of Mercer's thought-telegraph, by the aid of which she had told us the story of herself and her people. * * * * * I nodded and smiled, and pointed to the spot where she stood, trying to show her by my expression that I understood, and by my gesture, that she was to wait here for me. She smiled and nodded in return, and crouched again below the surface of the heaving sea. As I turned toward the beach, I caught a momentary glimpse of the two who had come with her. They were a man and a woman, watching me with wide, half-curious, half-frightened eyes. I recognized them instantly from the picture she had impressed upon my mind nearly a year ago. She had brought with her on her journey her mother and her father. Stumbling, my legs shaking with excitement, I ran through the water. With my wet trousers flapping against my ankles, I sprinted towards the house. I found Mercer in the laboratory. He looked up as I came rushing in, wet from the shoulders down, and I saw his eyes grow suddenly wide. * * * * * I opened my mouth to speak, but I was breathless. And Mercer took the words from my mouth before I could utter them. "She's come back!" he cried. "She's come back! Taylor--she has?" He gripped me, his fingers like steel clamps, shaking me with his amazing strength. "Yes." I found my breath and my voice at the same instant. "She's there, just where we put her into the sea, and there are two others with her--her mother and her father. Come on, Mercer, and bring your thought gadget!" "I can't!" he groaned. "I've built an improvement on it into the diving armor, and a central instrument on the sub, but the old apparatus is strewn all over the table, here, just as it was when we used it the other time. We'll have to bring her here." "Get a basin, then!" I said. "We'll carry her back to the pool just as we took her from it. Hurry!" And we did just that. Mercer snatched up a huge glass basin used in his chemistry experiments, and we raced down to the shore. As well as we could we explained our wishes, and she smiled her quick smile of understanding. Crouching beneath the water, she turned to her companions, and I could see her throat move as she spoke to them. They seemed to protest, dubious and frightened, but in the end she seemed to reassure them, and we picked her up, swathed in her hair as in a silken gown, and carried her, her head immersed in the basin of water, that she might breathe in comfort, to the pool. It all took but a few minutes, but it seemed hours. Mercer's hands were shaking as he handed me the antenna for the girl and another for myself, and his teeth were chattering as he spoke. "Hurry, Taylor!" he said. "I've set the switch so that she can do the sending, while we receive. Quickly, man!"
