It was like that famed voyage in another way, too. The men found little to do as they passed on at high speed through the vast realm of space. The chronometer pointed out the hours with exasperating slowness. The six hours that were to elapse before the first stop seemed as many days. They had thought of this trip as a wonderful adventure in itself, but the soundless continued monotony was depressing. They wandered around, aimlessly. Wade tried to sleep, but after lying strapped in his bunk for half an hour, he gave up in despair. Arcot saw that the strain of doing nothing was not going to be good for his little crew and decided to see what could be done about it. He went down to the laboratory and looked for inspiration. He found it. "Hey! Morey! Wade! Fuller! Come on down here! I've got an idea!" he called. They came to find him looking meditatively at the power pack from one of the flying suits he had designed. He had taken the lux metal case off and was looking at the neat apparatus that lay within. "These are equipped for use with the space suits, of course," Morey pointed out, "and that gives us protection against gases. But I wonder if we might install protection against mechanical injury--with intent to damage aforethought! In other words, why not equip these suits with a small invisibility apparatus? We have it on the ship, but we might need personal protection, too." "Great idea," said Wade, "provided you can find room in that case." "I think we can. We won't need to add anything but a few tuning devices, really, and they don't take a whale of a lot of power." Arcot pointed out the places where they could be put; also, he replaced some of the old induction coils with one of his new storage cells and got far higher efficiency from the tubes. But principally, it was something to do. Indeed, it was so thoroughly something to do that the six hours had almost elapsed before they realized it. In a very short time, they returned again to the control room and strapped themselves in. Arcot reached toward the little red switch that controlled the titanic energies of the huge coil below and pulled it back a quarter of the way. "There go the ghosts!" he said. The images had quickly disappeared, seemingly leaping away from them at terrific speed as the space in which the ship was enclosed opened out more and more and the curvature decreased. They were further away from themselves! Easing back a quarter at a time, to prevent sparks again flying about in the atmosphere of the ship, Arcot cut the power to zero, and the ship was standing still once more. They hurriedly dived to the observatory and looked eagerly out the window. Far, far behind them, floating in the marvelous, soft, utter blackness of space, was a shining disc made up of myriads of glowing points. And it didn't seem to be a huge thing at a great distance, but simply a small glowing object a few feet outside the window.
