There was nothing to be gained by examining the peculiar machine, and therefore the one quick glance sufficed. If Vic and Hope had gone this route, I was anxious to follow. I glanced down at the papers in my hand, and slowly turned the first dial on the little instrument board, narrowly watching the hand of the meter beside it, as Vic had instructed. The hand moved slowly, like the hand of an oil-gauge in which the pressure is gradually built up. Twenty-one ... twenty-five ... twenty-six ... _twenty-seven_. I waited a moment, conscious only of the faint hum of a generator at the other end of the room, and the quivering hand of the meter. I turned the dial back an imperceptible degree, and the hand steadied down exactly upon the numerals "2700." Then I touched the next dial. This second dial was no more than a thin disk of hard rubber or bakelite, with a red scratch-mark on one side. On the panel itself, far to the right of the dial's zero point, was the red scratch-mark that matched it. When the two coincided--well, something happened. I was conscious of a faint glow from above as I moved the dial slowly, so that its red mark approached the stationary one upon the panel. I glanced up swiftly. * * * * * Each of the little blobs of quartz was glowing; each with a light of different color. One was a rich amber, one a pale green, one a vivid, electric blue, and one was fiery red. The intensity of the light increased steadily as I moved the dial. I could not only see the light; I could feel it. It beat upon my body; throbbed all around me. I had a feeling that the mingling rays of light conflicted with each other. It seemed to me for a moment that I was growing as light as air; that my feet were drifting off the floor, and then, as the red line of the dial came closer to the indicated point, the feeling left, and I suddenly seemed very heavy. I could hardly support my own weight; my legs were trembling with the burden; sweat broke out over my whole body; the rays of light beat down upon me fiercely, overpoweringly.... Desperately, I quickly turned the dial until the two red marks coincided. A great weight, soft and enveloping, seemed to drop upon me. The senses of sight and hearing and feeling all left me. I could only think--and my thoughts were horrible. Then, suddenly, there was a terrific crash of sound, and my senses returned. I looked around. It seemed that an instant before I had been standing there in Vic's laboratory, slowly turning the second of the two dials, while the four lights beat down upon my body. And now ... and now I was standing in the open, on another world. A nightmare world that words seem inadequate to describe. * * * * *
