So Carvalho had really been responsible for the shooting. Lamoureux asked, "Why didn't you report that Carvalho started to yell and run?" "Well, Captain, you don't expect me to go around telling you things like that about another guy?" The words, "You fool," had been on Lamoureux's lips, but he bit them back. After all, who had been the bigger fool, McCracken or he himself, who had insisted that Carvalho get the radio? There was no doubt about the answer to that one. As for the occasion when the radio had begun to emit its mysterious code signals, the explanation for that was simple enough, too. The people who were in contact with Carvalho had sent their messages, not knowing whether strangers might be listening in, but not caring either. No one could make head or tail of the mysterious sounds but Carvalho. McCracken had, in fact, considered the noises a new strange form of static that had interfered when he tried to talk to Haskell. Lamoureux felt like asking McCracken to kick him in the pants. As that would have been bad for discipline, he substituted an order to get started back toward the ship. There was the faintest of chances that Carvalho had delayed, or had been forced by some accident to delay, his departure back to Earth. It was snowing harder than ever now, and it was difficult for Lamoureux to see more than fifty feet ahead of him. The rim of the Sun was blotted out so thoroughly that it was almost as dark as on a moonless night. Nevertheless he pressed on doggedly. It was not until six hours later, after he and the men had been wandering around aimlessly for a long enough time to have reached the ship and returned, that he admitted to himself that they were lost. V Not that it mattered a great deal. Lamoureux realized perfectly well that by this time the _Astrolight_ was on its return journey to Earth. All the same, it was disheartening to know that he was so completely unable to find his way about on this planet. The question now was what to do. They had little enough food, and not too much in the way of other supplies. They would have to live off the planet until some kind of rescue expedition had been organized to save _them_. If Kalinoff had done it, they could, too. Lamoureux's face burned as he pictured himself striding over to Kalinoff, staring at the man solemnly, and uttering those historic words, "Dr. Livingston, I presume." That was one scene that would never take place. It was growing colder by the hour. That meant that they would have to move over toward the Hot Side before the Sun sank beneath the horizon altogether. McCracken, the most cheerful of the lot, had a glum face as he asked, "What do we do now, Captain?" "First we eat, McCracken. Then we move toward the Sun. Just one word, McCracken. You like to shoot?" "Yes, sir." "Save your bullets. I have an idea we're going to need them before this little adventure of ours is finished."
