They neared the submarine, and saw numberless pitted spots in her body, where the heat ray had stabbed for a moment. In their excitement they missed their level by some feet, but clutching together they admitted more air and soon rose even with the starboard exit port. "Swim forward," Keith ordered. "Hurry!" The weird figures groped clumsily, and very slowly neared the port. The commander, in the van, at last reached out and gripped its jutting external controls. He could not work them at first: his hands were numb and awkward. As he tugged and struggled with them a shout rang in his headphone. It was McKegnie, scared to death. "Oh, hurry, Mr. Wells!" he yelled. "Quick! Quick, please! The octopis ship's comin', sir! The red light's back!" CHAPTER XI _To the Death_ The emergency steadied Keith's fingers. He got the door open and motioned Graham and six men inside the water chamber. The passage took but a minute. Then he sent the rest of the crew in, being himself the last to enter. When the chamber was finally empty, and Wells had stepped through the inner door onto the lower deck of the _NX-1_, a great sigh of relief broke from him. Never before had anything looked so good as that brilliantly lit deck with its familiar maze of machinery and bulkheads. "Thank God," he said simply, and his joy was shared by the whole crew. A new feeling had come over them. Back home--in their own submarine, their own element--they had at least a fighting chance with the octopi. But Keith let them waste no time. He knew that a final, desperate duel to the death with their foe still was ahead. "Above to the control room," he ordered. "Fast!" They lumbered up the connecting ramp. A disheveled, wild-eyed form met them. Keith couldn't help chuckling as he passed the now much thinner and paler cook, with the arsenal handy at his waist. On the deck of the control room lay a huge tentacled body, metal-scaled, with its dome of glass shattered and its great cold eyes staring unseeingly away. "I killed him," stammered McKegnie pridefully; "but Mr. Wells--look at that red light, sir!" Keith glanced rapidly at the location chart, ripping off his sea-suit as he did. The fateful red stud was moving swiftly down on the motionless green one. The men had surrounded McKegnie, laughing and slapping him on the back, but the commander's terse orders jerked them abruptly back to action. "The rectifiers, Graham: clean out this stale air. Sea-suits off; at emergency posts. Take the helm, Craig; you, Wetherby, trim the ship. No, no, Cook--keep away from the controls!" The _NX-1_ balanced herself; fresh air came rushing in, sweeping out the stale. Keith stared at the location chart, waiting for the submarine to be ready. The red light was almost upon them. "Right!" he roared at last. "Diving rudder controls, Graham! Full speed for the tunnel!" * * * * *
