ashamed of your kind." The background information he had about warfare in general made him feel skeptical in advance about the information he would presently be given. It would be what used to be called propaganda, given him under the name of briefing. It would agree with him that wars in general were horrible, but it would most plausibly point out—with deep regret—that this particular war, fought by this particular side, was both admirable and justified. "Which," said Calhoun darkly, "I wouldn't believe even if it were true!" II. "Information secured from others is invariably inaccurate in some fashion. A complete and reasoned statement of a series of events is almost necessarily trimmed and distorted and edited, or it would not appear reasonable and complete. Truly factual accounts of any series of happenings will, if honest, contain inconsistent or irrational elements. Reality is far too complex to be reduced to simple statements without much suppression of fact...." Manual, Interstellar Medical Service. P. 25. He was able to verify his guess about the means by which interstellar war became practical, when the Med ship was landed. Normally, a landing grid was a gigantic, squat structure of steel girders, half a mile high and a full mile in diameter. It rested upon bedrock, was cemented into unbreakable union with the substance of its planet, and tapped the ionosphere for power. When the Med ship reached the abysmal darkness of the nearest planet's shadow, there were long, long pauses in which it hung apparently motionless in space. There were occasional vast swingings, as if something reached out and made sure where it was. And Calhoun made use of his nearest-object indicator and observed that something very huge fumbled about and presently became stationary in emptiness, and then moved swiftly and assuredly down into the blackness which was the planet's night-side. When it and the planetary surface were one, the Med ship began its swift descent in the grip of landing grid-type force-fields. It landed in the center of a grid—but not a typical grid. This was more monstrous in size than any spaceport boasted. It was not squat, either, but as tall as it was wide. As the ship descended, he saw lights in a control-system cell, midway to the ground. It was amazing but obvious. The Med ship's captors had built a landing-grid which was itself a spaceship. It was a grid which could cross the void between stars. It could wage offensive war.
