"Sure I do." Jon laughed then, and the rest joined in. "But you'd have tromped on me if I'd been the one to say so." He turned quickly to face his father. "What do we do about this?" "_Ummm._ My suggestion would be for you to put on your suit and go out and open those covers you told me about. Give me the analyzer first, and I'll study the stuff's emanations when you get it uncovered." "I'll go out," Jak offered quickly. "You and Jon had better study it together. I don't know anything about it, but the kid does, and he'll be the one to handle it until you're well." "Better take the jack--that cover's heavy, remember?" Jon said, and Jak ran out. "I'd never have been able to do anything if it hadn't been for Jak's wiser advice," Jon said honestly as he brought the analyzer to his father from the instrument rack. "I'm apt to go off half-cocked, you know." Mr. Carver looked fondly up at his wife, who moved quickly to his side, and put her hand against his cheek. "A couple of grand fellows you raised, Darling," he said softly. "_We_ raised, you mean, Mr. C." She smiled down at him. "They fight all the time, but when it comes to the pinch, they work together and I know they really love and admire each other very much." Jon chuckled and spoke into the mike. "The folks are taking our good names in vain, Owl." "Yes, I heard them," came back the elder boy's voice from the speaker. "If they only knew what we really think of each other," and then followed his attempt at a sneering laugh. In their visiplates those inside the ship could see Jak, in his spacesuit, trotting awkwardly across the sand toward the cache. He carried the jack, and when he got there, used it to raise the heavy cover and throw it back. He jumped into the hole and took the cover off the smaller box. Then scrambled quickly out and ran some distance away. "Shall I come back now, or wait here to cover it again?" he asked over his suit-sender. "Maybe you'd better wait out there a few minutes," his father replied into the mike attached to his seat. "If we can't figure out something in a fairly short time, I'll tell you and you can recap the boxes and come back." He busied himself adjusting the analyzer, and he and young Jon studied the lines carefully for quite a time. Finally the father roused. "This is going to take a lot of study and work," he told his younger son. Then he spoke into the mike. "Better come back in, Jak." He turned his head again to face the boy with him. "Did you find a lead box, Jon?" "No, sir, we haven't anything like that in our stores," Jon answered. "But there is quite a roll of lead foil. Can we do anything with that?" "How much is there? And how thick is it?" "The foil's twenty inches wide and about twelve feet long," Jon reported as he came back after a quick run to the storeroom to measure the foil. He had delayed a moment or two at the lock to help Jak out of his suit. "It's a thirty-second thick."
