Seaton pointed his glass eagerly in the direction indicated. "Great Cat!" he ejaculated. "I'll say that's some moon! Wouldn't that rattle your slats? And there's DuQuesne's bus, too, on the right edge. Get it?" As they stood up, Seaton's mood turned to one of deadly earnestness, and a grave look came over Crane's face as the seriousness of their situation dawned upon them. Trained mathematicians both, they knew instantly that that unknown world was of inconceivable mass, and that their chance of escape was none too good, even should they abandon the other craft to its fate. Seaton stared at Crane, his fists clenched and drops of perspiration standing on his forehead. Suddenly, with agony in his eyes and in his voice, he spoke. "Mighty slim chance of getting away if we go through with it, old man.... Hate like the devil.... Have no right to ask you to throw yourself away, too." "Enough of that, Dick. You had nothing to do with my coming: you could not have kept me away. We will see it through." Their hands met in a fierce clasp, broken by Seaton, as he jumped to the levers with an intense: "Well, let's get busy!" In a few minutes they had reduced the distance until they could plainly see the other vessel, a small black circle against the faintly luminous disk. As it leaped into clear relief in the beam of his powerful searchlight, Seaton focused the great attractor upon the fugitive car and threw in the lever which released the full force of that mighty magnet, while Crane attracted the attention of the vessel's occupants by means of a momentary burst of solid machine-gun bullets, which he knew would glance harmlessly off the steel hull. * * * * * After an interminable silence, DuQuesne drew himself out of his seat. He took a long inhalation, deposited the butt of his cigarette carefully in his ash tray, and made his way to his room. He returned with three heavy fur suits provided with air helmets, two of which he handed to the girls, who were huddled in a seat with their arms around each other. These suits were the armor designed by Crane for use in exploring the vacuum and the intense cold of dead worlds. Air-tight, braced with fine steel netting, and supplied with air at normal pressure from small tanks by automatic valves, they made their wearers independent of surrounding conditions of pressure and temperature. "The next thing to do," DuQuesne stated calmly, "is to get the copper off the outside of the ship. That is the last resort, as it robs us of our only safeguard against meteorites, but this is the time for last-resort measures. I'm going after that copper. Put these suits on, as our air will leave as soon as I open the door, and practically an absolute vacuum and equally absolute zero will come in."
