The moment following was of such swift action as to defy the memory. In my leap upon the Neptunian beside me it had been my first object to knock his tube from his grasp before he could loose its rays upon me, and so swift and sudden was my attack that I did so, as did Marlin with the other guard. With the same motion, even as the guard's seven great limbs reached toward me, I had grasped his big disk-body and then with a superhuman effort had raised it in my arms and had cast him from me, down through the opening in the section's floor to crumple against the floor of one of the sections below! I whirled, saw that the other guard had gripped Marlin and was bearing him down, and then even as there came from beneath and from the Neptunian leader at the controls staccato cries of alarm, I had gripped that other guard likewise and hurled him across the cylinder to strike with stunning force against its wall! Then Marlin and I were whirling toward the Neptunian leader at the control-standard, but in the moment that we turned toward him we stopped short. For that Neptunian had leaped aside from the controls of the cylinder and had swiftly drawn his own ray-tube! CHAPTER VIII Prisoned on Triton Nothing, I know now, of our own doing could ever have saved us from the death that in that moment loomed dark and close above us. For, as the Neptunian leader raised the tube toward us, I knew that before ever a leap could take us across the cylinder to him, the pencil-like rays of force from his tube would be tearing through us. For that split-second, therefore, escape seemed impossible, and then before we could fully realize the situation there came an interruption. The currents of warmer air from the opening just beneath, down through which the cylinder had been dropping with the others, were sweeping still upward with great force around the cylinder. Only the Neptunian's grasp on the controls had kept the cylinder heading down through those currents, and now, as he leaped away from the controls for the moment and drew his tube, those currents immediately seized upon the unguided cylinder and in the next moment had whirled it over and sidewise with immense speed and power! And as it whirled thus over, Marlin and myself and the Neptunian before us were thrown instantly and indiscriminately to the cylinder's side!
