The Enlissa weapon was fired at Kandoris at 30:00 hours. Spaceships posted along the long line of fire between the satellite of Kandoris VI and the sun itself had sent out instrument-filled drones in the path of the beam to check the beam frequency. The time required for the subetheric wave to travel the eight hundred million miles from the planetary orbit to primary was too short to be measured. As far as the recording instruments were concerned, the beam was instantaneous. The projector itself was fired by remote control; there were no personnel within three miles of the Enlissa projector when it went off. The resultant recordings were run through the differential analyzers, and the final graphs were delivered to Kiffer Samm. After four hours of working with the data, Kiffer made his report to Roysland. "It's an odd wave length," he said. "Actually, it's a harmonic of three different basic frequencies. Look here: the thing is definitely frequency modulated, but it's a comparatively simple thing." He ran his finger along the primary recordings. "The thing wouldn't really have to be run through the differentials; it could be figured out with a slipdisk. "The thing that makes it different is the extremely short wave length. The longest of the three has a wave length of eighty thousand kilometers, and the shortest is forty-two thousand kilometers. In a subetheric beam, that's the equivalent of hard X-rays--damned high frequency." Roysland looked at the recordings carefully. "Is there any reason why this particular wave length should have any effect on the human brain?" Kiffer looked at the graphs for a long time. When he finally looked up, he said: "I don't know for sure; mind if I call Bilford?" Roysland shook his great head. "Go ahead; I don't mind." When Bilford's image flickered into existence, Roysland kept his mouth shut while Kiffer showed the psychometrist the recordings of the energy from the Enlissa projector. Bilford listened and looked and frowned. "The recordings actually don't make sense to me," he admitted. "I'm a psychometrist, not a subelectronocist. "If you could translate those recordings from subetheric to their electromagnetic equivalents, I might be able to make something out of it." The conversion didn't take long; all Kiffer had to do was run the stuff through the analyzer and punch in a correction factor. Bilford stared at the corrected graphs and compared them with tracings of his own. "I don't see any correlation," he said at last. "This may take a bit of work. There may be multiple harmonics of the basic stuff involved, of course; but frankly I can't see that the subetherics have anything in common with the electromagnetics as far as this area is concerned." For the first time, Roysland spoke. "Try a combination-permutation synthesis. See what you get--O.K.?"
