"Then our goose is cooked. I couldn't pull away from it with everything I had, couldn't even swing out enough to make an orbit, either hyperbolic or elliptical around it. With a reserve bar you will be able to make an orbit, but you can't get away from it." "Thanks for the dope. That saves our wasting some effort. Our power-plant can be doubled up in emergencies, thanks to Martin's cautious old bean. We'll simply double her up and go away from here." * * * * * "There is one thing we didn't consider quite enough," said Crane, thoughtfully. "I started to faint back there before the full power of even one motor was in use. With the motor doubled, each of us will be held down by a force of many tons--we would all be helpless." "Yes," added Dorothy, with foreboding in her eyes, "we were all unconscious on the way out, except Dr. DuQuesne." "Well, then, Blackie and I, as the huskiest members of the party, will give her the juice until only one of us is left with his eyes open. If that isn't enough to pull us clear, we'll have to give her the whole works and let her ramble by herself after we all go out. How about it, Blackie?" unconsciously falling into the old Bureau nickname. "Do you think we can make it stop at unconsciousness with double power on?" DuQuesne studied the two girls carefully. "With oxygen in the helmets instead of air, we all may be able to stand it. These special cushions keep the body from flattening out, as it normally would under such a pressure. The unconsciousness is simply a suffocation caused by the lateral muscles being unable to lift the ribs--in other words, the air-pumps aren't strong enough for the added work put upon them. At least we stand a chance this way. We may live through the pressure while we are pulling away, and we certainly shall die if we don't pull away." After a brief consultation, the men set to work with furious haste. While Crane placed extra bars in each of the motors and DuQuesne made careful observations upon the apparent size of the now plainly visible world toward which they were being drawn so irresistibly, Seaton connected the helmets with the air-and oxygen-tanks through a valve upon the board, by means of which he could change at will the oxygen content of the air they breathed. He then placed the strange girl, who seemed dazed by the frightful sensation of their never-ending fall, upon one of the seats, fitted the cumbersome helmet upon her head, strapped her carefully into place, and turned to Dorothy. In an instant they were in each other's arms. He felt her labored breathing and the wild beating of her heart, pressed so closely to his, and saw the fear of the unknown in the violet depths of her eyes, but she looked at him unflinchingly. "Dick, sweetheart, if this is good-bye...." He interrupted her with a kiss.
