"I'll say we do," Jak chimed in. "There's so much yet you can teach us. Why, we've only begun learning most of the things we want to know." Mr. Carver smiled up at his sons. "I'm always glad to tell you anything I can, Fellows. It's good to see you growing up, though." He turned his head to face Jon more directly. "What's that about a new system you rigged up so you can land and take off with only one switch?" Jon explained, and the two were soon deep in technical talk of electronic relays and cells, and automatic switch-overs. Finally, Mrs. Carver came in with a tray of lunch for her husband, and told the boys their food was on the table. "All right, you chaps, go and eat," Mr. Carver said. "I'll take another nap while you're out this afternoon. Then maybe I'll feel up to talking some more this evening, and going over these reports with you." * * * * * The second day later the boys finished their re-checking, and came back to the ship in midafternoon. Their father was again awake, and they went in to see him. "We're all done here, Pop, so what say we go back to that fuel-metal cache and see about getting the stuff aboard?" Jon asked. "I guess from all you've said that's the most important thing now," he agreed after a moment's consideration. "Only thing is, I've been wondering if you couldn't move me into the control room, and fix a couch for me there?" "Sure, that's easy," Jak told him. But Jon frowned in thought. "Yes, we can do it, but we'll have to figure out first how to fasten the cot down and then make some arrangement so you can stand any acceleration we may have to use." "How about fixing the co-pilot's seat into a bunk?" "Hey, that's the ticket!" Jon brightened. He ran out and soon was helping his mother gather blankets, sheets and pillows, and going with Jak to bring an extra mattress from the storeroom. They set the seat to recline, and then while Mrs. Carver was making up the bed, the boys carried their father--a much lighter load now than when he had first been hurt--and put him in his new bed. "Say, this is all right!" Mr. Carver exclaimed after Jon had lowered the co-pilot's visiplate so his father could look into it without distortion or neck-craning. "All the comforts of home." He grinned at his wife. She stooped and kissed him. "Be sure and let us know any time you get too tired, though, Mr. C." "I will, Honey," he assured her. "But actually, I'm so comfortable I don't see why I can't stay here as well as in bed, until the leg's strong enough to start getting up."
