here." Stine nodded agreement and Brion relaxed a bit. He had just relieved himself of his entire knowledge of Societics and it had sounded authentic. "The more I look at it the more I believe that this is a physical problem; something to so with the exotic and massive adjustments the Disans have made to this hellish environment. Could this tie up in any way with their absolutely suicidal attitude [Pg 106]towards the cobalt bombs?" [Pg 106] "Could it? Could it?" Dr. Stine paced the floor rapidly on his stocky legs, twining his fingers behind his back. "You are bloody well right it could. Someone is thinking at last and not just punching bloody numbers into a machine and sitting and scratching while waiting for the screen to light up with the answers. Do you know how Disans exist?" Brion shook his head no. "The fools here think it disgusting, but I call it fascinating. The have found ways to join in a symbiotic relationship with the life forms on this planet. Even a parasitic relationship. You must realize, that living organisms will do anything to survive. Castaways at sea will drink any liquid at all in their search for water. Disgust at this is only the attitude of the over-protected who have never experienced extreme thirst or hunger. Well, here on Dis you have a planet of castaways." Stine opened the door of the pharmacy. "This talk of thirst makes me dry." With economically efficient motions he poured grain alcohol into a beaker, thinned it with distilled water and flavored it with some flavor crystals from a bottle. He filled two glasses and handed Brion one. It didn't taste bad at all. "How do you mean parasitic, doctor? Aren't we all parasites of the lower life forms? Meat animals, vegetables and such?" "No, no—you miss the point! I speak of parasitic in the exact meaning of the word. You must realize that to a biologist there is no real difference between a parasitism, symbiosis, mutualism, biontergasy, commensalism—" "Stop, stop!" Brion said. "Those are just meaningless sounds to me. If that is what makes this planet tick, I'm beginning to see why the rest of the staff has that lost feeling." "It is just a matter of degree of the same thing. Look. You have a kind of crustacean living in the lakes here, very much like an ordinary crab. It has large claws in which it holds anemones, tentacled sea animals with no power of motion. The crustacean waves these
