"Leucocytes can run through several thousand generations of evolution in six months," Pat Mead finished. "When they reached to a point where they would absorb Minos food, he planted them back in the people he had taken them from." "What was supposed to happen then?" Max asked, leaning forward. "I don't know exactly how it worked. He never told anybody much about it, and when I was a little boy he had gone loco and was wandering ha-ha-ing around waving a test tube. Fell down a ravine and broke his neck at the age of eighty." "A character," Max said. Why was she afraid? "It worked then?" "Yes. He tried it on all the Meads the first year. The other settlers didn't want to be experimented on until they saw how it worked out. It worked. The Meads could hunt, and plant while the other settlers were still eating out of hydroponics tanks." "It worked," said Max to Len. "You're a plant geneticist and a tank culture expert. There's a job for you." "Uh-_uh_!" Len backed away. "It sounds like a medical problem to me. Human cell control--right up your alley." "It is a one-way street," Pat warned. "Once it is done, you won't be able to digest ship food. I'll get no good from this protein. I ate it just for the taste." Hal Barton appeared quietly beside the table. "Three of the twelve test hamsters have died," he reported, and turned to Pat. "Your people carry the germs of melting sickness, as you call it. The dead hamsters were injected with blood taken from you before you were de-infected. We can't settle here unless we de-infect everybody on Minos. Would they object?" "We wouldn't want to give you folks germs," Pat smiled. "Anything for safety. But there'll have to be a vote on it first." The doctors went to Reno Ulrich's table and walked with him to the hangar, explaining. He was to carry the proposal to Alexandria, mingle with the people, be persuasive and wait for them to vote before returning. He was to give himself shots of cureall every two hours on the hour or run the risk of disease. * * * * * Reno was pleased. He had dabbled in sociology before retraining as a mechanic for the expedition. "This gives me a chance to study their mores." He winked wickedly. "I may not be back for several nights." They watched through the viewplate as he took off, and then went over to the laboratory for a look at the hamsters. Three were alive and healthy, munching lettuce. One was the control; the other two had been given shots of Pat's blood from before he entered the ship, but with no additional treatment. Apparently a hamster could fight off melting sickness easily if left alone. Three were still feverish and ruffled, with a low red blood count, but recovering. The three dead ones had been given strong shots of adaptive and counter histamine, so their bodies had not fought back against the attack.
