Some minutes later they saw with satisfaction that their mother's color was growing more natural, and her body tremors were slowing from the combined warmth of the extra blankets and hot drink. Only then did the boys stop to help each other out of their suits. "Thanks for the help, Mother, but don't you know enough to wear a suit in weather as cold as this?" Jak's worry made his voice sharp. "Yes, who's always fussing about us being careful?" Jon added. "Then pull a stunt like this." Their mother looked up at them, and the old impish grin they had seen so seldom of late came onto her face. "You've got me, Chums," she drawled. "From now on I reckon I'll keep my big mouth shut." Jon howled, and Jak added in the same sort of drawl, "Well, now, I wouldn't go for to say it was 'big,'" and ducked as she slapped out at him. Soon the two boys sobered down. "We'd better go examine the lock and make sure no crystals got in," Jak said. "Yow, I forgot about that!" Jon sprang forward. "We sure don't want any of them in or on the ship." 9 Despite Jon's desire to get away from this unfriendly world that bore his name, he was careful to see that the signal-marker was set out and functioning, and that the ship's log contained as complete a record of the resources and data on the planet as was required by the Terran Colonial Board. The same was true of Four's four moons. Jak checked all the work, nor did they leave Four until both boys were satisfied it was complete. Their mother was a great help in taking the numerous photographs needed, having become quite competent in handling the cameras. She was so relieved at the steady progress of her husband's convalescence that she put extra enthusiasm into her photography. The family still felt that Mr. Carver should be kept as quiet as possible and away from any mental strain in connection with the ship and the planet mapping and, in his weakness, he seemed content to leave it that way for the time being. He asked few questions and accepted the reassuring answers contentedly. Nor, even though Jon wished to get back to friendly Two as soon as he could, did he forget they still had to visit Planet Five, and scout and record that. So, as soon as they were completely done on Four, he lost no time setting course for Five. Once on the way, he announced his names for the four moons of Four, and now it was Jak's turn to scoff. "Well, if you can name yours after flowers, I don't see why you've got any kick coming because I name mine after fish," Jon asserted. "I leave it to you, Mom--aren't Tuna, Betta, Sturgeon and Porpoise nice names?" "I think they are fine, just as I think Zinnia and Begonia are aptly named," she said diplomatically.
