head to foot—an old, queerly, unnaturally old man now—unnerved. His fingers could hardly hold the test tubes. His thoughts were flying. Babs was here, come down from the world above. It was disaster—the thing he had feared all these years. He suddenly heard a voice. "Father!" And again: "Father!" A tiny voice, down by his shoe tops. Two small figures were there on the floor beside him. They were both panting, winded by running. They were enlarging. It was Alan and Glora, who had followed Polter from the boat, then diminished again and had come running through the tiny crack under the metal door of the laboratory. They grew to a foot in size, down by Dr. Kent's legs. He was too unnerved to stand; he sat in a chair while Alan swiftly told him what had happened. Babs was in the golden cage. Dr. Kent knew that; but none of them knew what had happened to me. "We must make you small, Father. We have the drugs, here with us." "Yes! How much have you? Show me. Oh, my boy, that you are here—and Babs—" "Don't you worry. We'll get away from him." Glora and Alan had almost reached Dr. Kent's size before[Pg 70] their excited fingers could get out the vials. They took some of the diminishing drug to check their growth. Alan handed his father a black vial. [Pg 70] "Yes, lad—" "No! Wait, that's the wrong drug. This other—" Dr. Kent had opened the vial. His trembling hand spilled some of the pellets, but none of them noticed it. "Father, this one." Alan held an opalescent vial. "Take this one." Glora said abruptly, "Listen! Is that someone coming?" They thought they heard approaching footsteps. A moment passed but no one came into the room. "Hurry," urged Glora. "That was nothing. We're waiting too long."
