Poised in mid-air, almost exactly in the center of the huge globular room, was a metal globe of some thirty feet in diameter. It was held, not by any solid girders, but by four narrow beams of light which mounted to it from widespread points of the convex room. Upon the entire surface of this thirty-foot globe, a group of masters were seated, in little, cup-like seats upon resilient stems. They swayed and nodded with movement. There seemed to be glowing wires and grids and thread-like beams of light carrying current. Light-threads shot from the mechanisms to the heads of the seated brains. All the devices were evidently in operation; and upon this poised central globe the attention of the audience was directed. Molo bent over me. "The Great Intelligence soon will see you." Snap, from the other side of Molo, whispered: "What are they doing up there?" The faint hiss and throb of the devices were audible. I stared, trying to understand. Images, and sounds, invisible and inaudible were being received from across the millions of miles of space, and they were being transmuted within the brains themselves. I saw that discs were fastened upon the bulging foreheads of the brains, upon which the tiny light-beams carrying the vibrations impinged. These brains, receiving "waves" of some unknown variety were, within the mechanism of the brain-cell, transmuting, translating the vibrations into things knowable. They were not seeing, not hearing, but _knowing_ what went on millions of miles across space! Again Molo bent over me. "They are about to show this audience what is happening on the three worlds." Upon the thirty-foot globe I saw now a dozen or so balls of about three-foot diameter. These had been dark and I had not noticed them. Now they began glowing, not from wires carrying the current, but from the little hands of the brains touching them. I stared at the brain nearest me. His flabby little arm was extended; his hand touched the image-ball; gave it light and color, like a fortune-teller of Earth with a crystal before her. Even though I was some sixty feet from it, I could see the moving images clearly, and recognized the scene. The Tappan Interplanetary Stage. Ships were rising; two of our spaceships mounting. And all in an instant the scene blurred, took form again. The red-green spires and minarets of Ferrok-Shahn. The Central Canal extended like a gash across the foreground; the "Mushroom Mountains" were in a line upon the horizon. Three Martian space-flyers slid up while we watched. And now Grebhar. The silver forest in all its shining beauty, where Venza was born. The sunlight sparkled on the river. A spaceship was rising in the distant sky over the shining forest. Beyond Anita, I heard Venza murmuring, "Home! If only we were there." I could feel Anita move to silence her. Molo was whispering: "They come. But we will be ready for them."
