The group broke up, each man going to his own quarters; to meet again in the First Section a minute or so before the zero time. Roger's "office" was now packed so tightly with machinery and supplies that but little room was left for the scientists. The gray monstrosity still sat unmoved behind his dials.
"But of what use is it, Roger?" the Russian physicist demanded. "Those waves are of some ultra-band, of a frequency immensely higher than anything heretofore known. Our screens should not have stopped them for an instant. It is a mystery that they have held so long, and certainly this single section will not be permitted to leave the planetoid without being destroyed."
"There are many things you do not know, Mirsky," came the cold and level answer. "Our screens, which you think are of your own devising, have several improvements of my own in the formulae, and would hold forever had I the power to drive them. The screens of this section, being smaller, can be held as long as will be found necessary."
"Power!" the dumbfounded Russian exclaimed. "Why, we have almost infinite power—unlimited—sufficient for a lifetime of high expenditure!"
But Roger made no reply, for the time of departure was at hand. He pressed down a tiny lever, and a mechanism in the power room threw in the gigantic plunger switches which launched against the Nevians the stupendous beam which so upset the complacence of Nerado the amphibian—the beam into which was poured recklessly every resource of power afforded by the planetoid, careless alike of burnout and of exhaustion. Then, while all of the attention of the Nevians and practically all of their maximum possible power output was being devoted to the neutralization of that last desperate thrust, the metal wall of the planetoid opened and the First Section shot out into space. Full-driven as they were, Roger's screens flared white as he drove through the temporarily lessened attack of the Nevians; but in their preoccupation the amphibians did not notice the additional disturbance and the section tore on, unobserved and undetected.
Far out in space, Roger raised his eyes from the instrument panel and continued the conversation as though it had not been interrupted.
"Everything is relative, Mirsky, and you have misused gravely the term 'unlimited.' Our power was, and is, very definitely limited. True, it then seemed ample for our needs, and is far superior to that possessed by the inhabitants of any solar system with which I am familiar; but the beings behind that red screen, whoever they are, have sources of power as far above ours as ours are above those of the Solarians."
"How do you know?"
"That power, what is it?"
"We have, then, the analyses of those fields recorded!" came simultaneous questions and exclamations.
