It was hours later when Morey awoke with a sudden premonition of trouble. He looked at the chronometer on the wall--he had slept twelve hours! They had gone beyond the million light year mark! It didn't matter, except it showed that something had happened to Arcot. Something had. Arcot was sound asleep in the middle of the library--exactly in the middle, floating in the room ten feet from each wall. Morey called out to him, and Arcot awoke with a guilty start. "A fine sentry you make," said Morey caustically. "Can't even keep awake when all you have to do is sit here and see that we don't run into anything. We've gone more than our million light years already, and we're still going strong. Come on--snap out of it!" "I'm sorry--I apologize--I know I shouldn't have slept, but it was so perfectly quiet here except for your deep-toned, musical snores that I couldn't help it," grinned Arcot. "Get me down from here and we'll stop." "Get you down, nothing!" Morey snapped. "You stay right there while I call the others and we decide what's to be done with a sleeping sentry." Morey turned and left to wake the others. He had awakened Wade and told him what had happened, and they were on their way to wake up Fuller, when suddenly the air of the ship crackled around them! The space was changing! They were coming out of hyperspace! In amazement, Morey and Wade looked at each other. They knew that Arcot was still floating helplessly in the middle of the room, but-- "Hold on, you brainless apes! We're turning around!" came Arcot's voice, full of suppressed mirth. Suddenly they were both plastered against the wall of the ship under four gravities of acceleration! Unable to walk, they could only crawl laboriously toward the control room, calling to Arcot to shut off the power. When Morey had left him stranded in the library, Arcot had decided it was high time he got to the floor. Quickly, he looked around for a means of doing so. Near him, floating in the air, was the book he had been reading, but it was out of reach. He had taken off his boots when he started to read, so the Fuller rocket method was out. It seemed hopeless. Then, suddenly, came the inspiration! Quickly, he slipped off his shirt and began waving it violently in the air. He developed a velocity of about two inches a second--not very fast, but fast enough. By the time he had put his shirt back on, he had reached the wall. After that, it was easy to shoot himself over to the door, out into the corridor and into the control room without being seen by Morey, who was in Wade's room. Just as Wade and Morey reached the doorway to the control room, Arcot decided it was time to shut the power off. Both of the men, laboring under more than eight hundred pounds of weight, were suddenly weightless. All the strength of their powerful muscles were expended in hurling them against the far wall.
