"Harl," Kir-Um said with great solemnity, "I believe we are standing in a citadel of science. A place where great, new theories and devices are propounded and deliberated. And that creature in there is the guiding hand of this stronghold of knowledge. The letter he is reading was undoubtedly written by the highest intellect of this world. As you say, this genius may have foreseen our coming and moved to nullify it. Spurred on by desperation, he created this marvelous weapon and thought to surprise our onrushing, confident armies with an impregnable defense. Quite by chance, we have stumbled upon this dastardly plot, before it could be brought to bear." "But what can we do?" Harl despaired. "The letter does not reveal the nature of this weapon. How can we combat something of which we know absolutely nothing? I am of the opinion we should abandon our conquest and die a slow, peaceful death on our own aging world." Kir-Um deliberated this advice, the deciding factor being a vision of the Grand Councilor rising up in all his wrath and condemning the two who had brought the bad news. "No, Harl. The Grand Councilor might not approve of such a course. To suggest such a thing would be to admit we have failed, and the Councilor does not tolerate failure. Without thought of the consequences, he might order us executed and deprive our planet of two of its greatest minds. No, that won't do." "We have no alternative," Harl pointed out, still whispering. "We cannot stand against such a weapon, and better to sacrifice ourselves than have our entire space fleet meet with destruction. If only our armies could come through the Ato-Decomposera Twunend-Materializationa Tutherend, perhaps we could surprise these scheming Earthlings and overwhelm them, before they could bring this tremendous force into play. But, unfortunately, we don't have the metal to build enough of the machines." Kir-Um nodded thoughtfully. "No, we can't stand against this weapon. But we can gain possession of it and put it to our own use!" Harl stared uncomprehendingly at Kir-Um. "You mean, ferret out this genius and force him to divulge the plans of his invention?" There was a gleam in Kir-Um's eye now. "Not only that, we'll secure a working model and take it with us, to study and build from. No doubt the weapon is complicated and, in this manner, we can gain first-hand knowledge of its working." "E-e-e-ump," Harl murmured softly. "Good, good, Kir-Um. It
