The central bulkheads seemed momentarily holding. Then little red lights in the panel board before me showed where in the hull corridors the doors were leaking, cracking, giving away, breaking under the strain. The whole ribbed framework of the vessel was strained and slued. The bulkhead sides no longer set true in the casements. Air was whining everywhere and pulling sternward. It was the last stand; I was aware that the alarm siren had ceased. There was a sudden stillness, with only the shouts of the remaining men at the exit-ports mingling with the whine of the wind and the roaring in my head. I felt detached, far-away; my senses were reeling. I staggered to the gauges of the Erentz system, the system whereby an oscillating current, circling within the double-shelled walls of hull and dome, absorbed into negative energy much of the interior pressure. The main walls of the vessel were straining outward. The _Cometara_ could collapse at any moment. I started for the catwalk door. The electro-telescope stood near it and I yielded to a vague desire to gaze into the eyepiece. The instrument was still operative. I swept it sternward. The enemy ship had not vanished. By what strange means, I cannot say, its velocity had been checked. A few thousand miles from us, it was making a narrow, close-angle turn. Coming back? I thought so. I suddenly realized my intention of having all the gravity-plates in neutral before abandoning the ship. I seized the controls now. An agony of fear was upon me that the shifting valves would fail. But they did not. The plates slid haltingly, reluctantly. I recall staggering to the catwalk. It seemed that the central bulkhead was breaking. There were fallen figures on the deck beneath me. I stumbled against the body of a man who had tangled himself in the stays of the ladder rail and was hanging there. I think I fell the last ten feet to the deck. The roaring in my ears, the bands tightening about my chest encompassed all the world. Then I was on my feet again, and I stumbled over another body. It was garbed in a space-suit, with the helmet beside it. I stripped it of the suit. I was panting, with all the world whirling in a daze, bursting spots of light before my eyes. Ten feet away down the deck was the opened door of the pressure chamber. A bloated figure came into my dreamlike vista, moving for the pressure door. It turned, saw me, came leaping and bent over me. I saw behind the vizor that it was Grantline. His bloated, gloved hands helped me don my suit. He helped me with my helmet. The metal tip on Grantline's gloved hand touched the contact-plate on my shoulder. His voice sounded from the tiny audiphone grid within my helmet. "Gregg! Thank God I found you! All right?" "Yes." My head was clearing. "I've got the chamber ready. We're the last, Gregg." I gripped his shoulder. "You're sure there's nobody else?" "No. I've been everywhere I could reach. The central bulkheads are almost gone."
