To right and left, like light, drove the deadly weapon-rays of our massed space-fliers as we seized the opportunity and leaped upon the Neptunians. Ample was the revenge we had upon them in that moment, since the concentrated rays tore through and wrecked hundreds of their own cylinders as we sprang upon them! Fleeing from before us for the moment, flashing away toward giant Neptune's tremendous green disk ahead, they strove to reform while we leaped after them and harried them with every weapon-ray which our space-fliers could emit. Swiftly, though, even as they rushed onward before us, the Neptunian cylinders were drawing together into a great mass again, into a great column-like formation, and as our own column-mass drove beside and after them with weapon-rays stabbing, their resistance abruptly stiffened, and they were racing in close formation once more beside our own mighty fleet, grappling once more with it in space as both rushed toward great Neptune. But we had struck a mighty blow at their disorganized masses in the moment of our opportunity. Fully two thousand of their cylinders had been swept to death by our rays before they had been able to mass again, and now but six thousand or less cylinders remained, racing ahead with our own four thousand or less fliers! The great green sphere of Neptune was looming colossal ahead and slightly beneath our two oncoming fleets, with behind and above it the bright little disk of Triton. It was toward Triton even in that wild moment that all of us were gazing, toward the source of the giant sun-ray that we must, somehow, halt. But now the battle around us had become so furious that we could spare no thought to aught else, since the two mighty fleets, stabbing ceaselessly at each other with their slender rays as they slowed their flashing progress forward, were rushing into the outer reaches of the atmosphere of huge Neptune! Its air was roaring about our whirling space-fliers as we shot through it, but as we shot on we saw that the Neptunian cylinders were going into annihilation swifter far than were our fliers! For they had formed and were racing beside us in their half-circle formation, while our own fliers at Marlin's command had leaped forward in a long column that could concentrate all its fire of rays upon the side of the Neptunian formation nearest us! And though slender rays tore lightning-like through fliers here and there across our own column, we saw that their cylinders beneath our fire were being wrecked in scores, in hundreds! In that vast running fight we were fast evening the odds against us!
