It would probably be too much to say that the fulfillment was surprised. An adult, fulfilled Cahuitan is so serene, so sedate, so inherently stable at any possible level of stress, that it is probably impossible for it to feel any such sensation or emotion as surprise, even at the instantaneous unveiling of a whole new universe of thought. It was, however, in a calm, passionless, and scholarly way, interested. Not what could be called intensely interested, perhaps, but really interested, nevertheless. As had been foreseen, the modes of thought of the Cahuitan and the linked Tellurians were different indeed. As has been shown, however, there were some points—the fulfillment could remember the emotions of its component products, even though it could no longer feel them—upon which even such divergent minds as those could find common ground. Also, it must be borne in mind that the Cahuitan was an able and seasoned thinker, trained for many millennia in the art, and that Neal Cloud was a Type Six mind; the only such mind then to be found in all Civilization. Hence, while it would serve no useful purpose here to go into detail as to how it was accomplished, a working understanding was at last attained. Cloud came to understand, as well as any being of material substance ever could, the beings of pure energy. The Cahuitan learned, and broadcast, that intelligent life could and did exist in intimate association with ultimately frigid matter. While the probability was small that there would ever be any considerable amount of fruitful intercourse between the two kinds of life, some live-and-let-live arrangement should be and would be worked out. There were thousands, yes, millions, of planets absolutely useless to anybody or anything known to man; planets harboring no life of any kind. The Patrol would be glad to set up, on any desired number of these barren planets, as many atomic power plants as the Cahuitans wanted; with controls set either to let go in an hour or to maintain stability for twenty five thousand Galactic Standard years. The Cahuitans would immediately extinguish all vortices not containing products, and would move all living products to the new planets as soon as the promised incubators were ready. “_Products_ indeed—they’re _babies_!” Joan insisted, when Cloud stepped the information down to her level. “And how can they possibly move them?” “Easily enough,” the fulfillment told Cloud. “Blankets of force will retain the warmth necessary for such short trips, provided each new incubator is waiting, warm, and ready.” “I see. But there’s one question I want to ask for myself,” and Cloud went on to explain about the unbelievably huge sphere that crossed Civilization’s vast expanse of space. “What’s the _reason_ for it?”
