Tode had said one day, with what Jim had taken for sarcasm, that they represented the wave series of a single sound extended in time to make four-dimensional action, but Jim had never considered the explanation seriously.
That sound, bringing back all Jim's memories of their experiments, brought him to his feet sharply. He swung around. The surface of the pool was a bubbling, seething mass of mud and water. And over its surface that faint violet haze was beginning to spread.
In the center where the light was thickest, something like a gyroscope appeared to be revolving. Out of the gyroscope something was beginning to project—that infernal tube of Lucius Tode. And Jim knew that in the heart of the flame that enormous, distorted face of Lucius Tode would again be visible.
The human nervous system can only endure a certain amount of impact. The sight of that ghastly flame, already condensing into a violet pillar, was more than Jim could stand. He dragged old Parrish to his feet and started off with him into the thickest part of the undergrowth.
A fearful scream behind him stopped him at the very edge of the scrub. He looked back, still supporting the half-conscious old man in his arms. The violet flame was shooting up in a straight pillar, the whole central portion of the pool was dry, and the waters were heaped up all around it.
From the slightly elevated spot where Jim stood, he could see Tode holding Lucille in his arms in the very heart of the fire, which threw a pale, fluorescent light over their faces. Tode was wearing a spotted skin, like that of a leopard, and Lucille was in the blue frock that she had worn when Jim and she had dinner together two evenings before.
Jim dropped old Parrish, shouted in answer, and dashed back like a madman down the slope into the solid wall of water.
e fought his way desperately through that wall, which seemed of the consistency of soft rubber or treacle, as if some subtle change had taken place in its molecular isomers. It adhered to him without wetting him, and he plunged through it, hearing Lucille cry out again, and yet again.
