style="font-size:15px;"> Plague. "What was the disease?" Hal Barton asked.
"Pretty gruesome, according to my father. They called it the melting sickness. The doctors died too soon to find out what it was or what to do about it."
"You should have trained for more doctors, or sent to civilization for some." A trace of impatience was in George Barton's voice.
Pat Mead explained patiently, "Our ship, with the power plant and all the books we needed, went off into the sky to avoid the contagion, and never came back. The crew must have died." Long years of hardship were indicated by that statement, a colony with electric power gone and machinery stilled, with key technicians dead and no way to replace them. June realized then the full meaning of the primitive sheath knife and bow.
"Any recurrence of melting sickness?" asked Hal Barton.
"No."
"Any other diseases?"
"Not a one."
Max was eyeing the bronze red-headed figure with something approaching awe. "Do you think all the Meads look like that?" he said to June on the intercom. "I wouldn't mind being a Mead myself!"
Their job had been made easy by the coming of Pat. They went back to the ship laughing, exchanging anecdotes with him. There was nothing now to keep Minos from being the home they wanted, except the melting sickness, and, forewarned against it, they could take precautions.
The polished silver and black column of the Explorer seemed to rise higher and higher over the trees as they neared it. Then its symmetry blurred all sense of specific size as they stepped out from among the trees and stood on the edge of the meadow, looking up.
"Nice!" said Pat. "Beautiful!" The admiration in his voice was warming.
"It was a yacht," Max said, still looking up, "second hand, an old-time beauty without a sign of wear. Synthetic diamond-studded control board and murals on the walls. It doesn't have the new speed drives, but it brought us thirty-six light years in one and a half subjective years. Plenty good enough."
The tall tanned man looked faintly wistful, and June realized that he had never had access to a full library, never seen a movie, never experienced luxury. He had been born and raised on Minos.
"May I go aboard?" Pat asked hopefully.
Max unslung the specimen kit from his shoulder, laid it on the carpet of plants that covered the ground and began to open it.
"Tests first," Hal Barton said. "We have to find out if you people still carry this so-called melting sickness. We'll have to de-microbe you and take specimens before we let you on board. Once on, you'll be no good as a check for what the other Meads might have."
Max was taking out a rack and a stand of preservative bottles and hypodermics.
"Are you going to jab me with those?" Pat asked with interest.
"You're just a specimen animal to me, bud!" Max grinned at Pat Mead, and Pat grinned back. June saw that they were friends already, the tall pantherish colonist, and the wry, black-haired doctor. She felt a stab of guilt because she loved Max and yet could pity him for being smaller and frailer than Pat Mead.
"Lie down," Max told him, "and hold still. We need two spinal fluid samples from the back, a body cavity one in front, and another from the arm."
Pat lay down obediently. Max knelt, and, as he spoke, expertly swabbed and inserted needles with the smooth speed that had made him a fine nerve surgeon on Earth.
High above them the scout helioplane came out of an opening in the ship and angled off toward the west, its buzz diminishing. Then, suddenly, it veered and headed back, and Reno Unrich's voice came tinnily from their earphones:
"What's that you've got? Hey, what are you docs doing down there?" He banked again and came to a stop, hovering fifty feet away. June could see his startled face looking through the glass at Pat.
Hal Barton switched to a narrow radio beam, explained rapidly and pointed in the direction of Alexandria. Reno's plane lifted and flew away over the odd-colored forest.
"The plane will drop a note on your town, telling them you got through to us," Hal Barton told Pat, who was sitting up watching Max dexterously put the blood and spinal fluids into the right bottles without exposing them to air.
"We won't be free to contact your people until we know if they still carry melting sickness," Max added. "You might be immune so it doesn't show on you, but still carry enough germs – if that's what caused it – to wipe out a planet."
"If you do carry melting sickness," said Hal Barton, "we won't be able to mingle with your people until we've cleared them of the disease."
"Starting with me?" Pat asked.
"Starting with you," Max told him ruefully, "as soon as you step on board."
"More needles?"
"Yes, and a few little extras thrown in."
"Rough?"
"It isn't easy."
A few minutes later, standing in the stalls for spacesuit decontamination, being buffeted by jets of hot disinfectant, bathed in glares of sterilizing ultraviolet radiation, June remembered that and compared Pat Mead's treatment to theirs.
In the Explorer, stored carefully in sealed tanks and containers, was the ultimate, multi-purpose cureall. It was a solution of enzymes so like the key catalysts of the human cell nucleus that it caused chemical derangement and disintegration in any non-human cell. Nothing could live in contact with it but human cells; any alien intruder to the body would die. Nucleocat Cureall was its trade name.
But the cureall alone was not enough for complete safety. Plagues had been known to slay too rapidly and universally to be checked by human treatment. Doctors are not reliable; they die. Therefore spaceways and interplanetary health law demanded that ship equipment for guarding against disease be totally mechanical in operation, rapid and efficient.
Somewhere near them, in a series of stalls which led around and around like a rabbit maze, Pat was being herded from stall to stall by peremptory mechanical voices, directed to soap and shower, ordered to insert his arm into a slot which took a sample of his blood, given solutions to drink, bathed in germicidal ultraviolet, shaken by sonic blasts, breathing air thick with sprays of germicidal mists, being directed to put his arms into other slots where they were anesthesized and injected with various immunizing solutions.
Finally, he would be put in a room of high temperature and extreme dryness, and instructed to sit for half an hour while more fluids were dripped into his veins through long thin tubes.
All legal spaceships were built for safety. No chance was taken of allowing a suspected carrier to bring an infection on board with him.
June stepped from the last shower stall into the locker room, zipped off her spacesuit with a sigh of relief, and contemplated herself in a wall mirror. Red hair, dark blue eyes, tall…
"I've got a good figure," she said thoughtfully.
Max turned at the door. "Why this sudden interest in your looks?" he asked suspiciously. "Do we stand here and admire you, or do we finally get something to eat?"
"Wait a minute." She went to a wall phone
