"A minute or so, I guess. Why?"
"Figuring how long I'll have to handle the controls. A minute is plenty of time, as I can have everything set up, and only have one switch to throw."
Mr. Carver reached out a hand and patted his wife's cheek as she stood by his side. "It's going to work out all right, Honey." His voice was bright and assured. "These boys of ours are really up on their stuff."
"Yes," she agreed. "I know they know what they are doing, and that you are checking them carefully. It is mainly my not knowing that makes me afraid sometimes." She gave him a lopsided smile. "I hate being the weak member of the party."
"You're nothing of the kind!" He grinned as the boys murmured protests which meant the same thing. "You're the best fellow in the gang." And he blew her a kiss as the boys helped him into his pack and saw to it that he was securely and comfortably strapped in. Then they did the same for their mother.
Jak went to his room and came back quickly with his hypodermic needles, and the bottles of glucose and concentrates. He put these beside the test tube with the new fluid.
Carefully he administered the dosage of nutrients to the other three, then lay down on his recline seat and gave himself his own dose. He rested there for a couple of minutes, then rose. Carefully he drew four cubic centimeters of the new, clear fluid into his needle, then approached his mother. "Ready?" he asked, smiling, but with tight lips.
She pushed up her left sleeve. "Ready, Son." And now her voice was soft but steady.
He tipped the needle into the light, carefully expelled a couple of drops to make sure all air was out of the tube. Then quickly and with a sureness he had trouble making his hands achieve, he pushed the slim needle into her arm, and injected the drug. With the ball of his thumb he rubbed the puncture gently for a moment. "Sleep tight, Mother." He smiled and leaned down to kiss her.
"Who's next?" He turned to the others.
