He cut into artificial space, waited ten seconds, then cut back. The scene before him changed. It seemed a different world. The light was very dim, so dim he could scarcely see the images on the view plate. They were so deep a red that they were very near to black. Even Sirius, the flaming blue-white star was red. The darting Thessian ships were moving quite slowly now, moving at a speed that was easy to follow. Their rays, before ionizing the air brilliantly red, were now dark. The instruments showed that the screen was no longer encountering serious loading, and, further, the load was coming in at a frequency harmlessly far down the radio spectrum! Arcot stared in wide-eyed amazement. What could the Thessians have done that caused this change? He reached up and increased the amplification on the eyes to a point that made even the dim illumination sufficient. Wade was staring in amazement, too. "Lord! What an idea!" suddenly exclaimed Arcot. Wade was staring at Arcot in equally great amazement. "What's the secret?" he asked. "Time, man, time! We are in an advanced time plane, living faster than they, our atoms of fuel are destroyed faster, our second is shorter. In one second of our earthly time our generators do the same amount of work as usual, but they do many, many times more work in one second, of the time we were in! We are under the advanced time field." Wade could see it all. The red light--normal light seen through eyes enormously speeded in all perceptions. The change, the dimness--dim because less energy reached them per second of their time. Then came this blue light, as they reached the X-ray spectrum of Sirius, and saw X-rays as normal light--shielded, tremendously shielded by the atmosphere, but the enormous amplification of the eyes made up for it. The remaining Thessians seemed to get the idea simultaneously, and started for Arcot in his own time field. The Thessian ship appeared to be actually leaping at him. Suddenly, his speed increased inconceivably. Simultaneously, Arcot's hand, already started toward the space-control switch, reached it, and pushed it to the point that threw the ship into artificial Space. The last glimmer of light died suddenly, as the Thessian ship's bow loomed huge beside the _Ancient Mariner_. There was a terrific shock that hurled the ship violently to one side, threw the men about inside the ship. Simultaneously the lights blinked out. Light returned as the automatic emergency incandescent lights in the room, fed from an energy store coil, flashed on abruptly. The men were white-faced, tense in their positions. Swiftly Morey was looking over the indicators on his remote-reading panel, while Arcot stared at the few dials before the actual control board. "_There's an air pressure outside the ship!_" he cried out in surprise. "High oxygen, very little nitrogen, breathable apparently, provided there are no poisons. Temperature ten below zero C."
