So that as our great fleet of space-fliers, holding to its regular formation, flashed on and on and on through the great gulf of space, on out through the outer vast reaches of the solar system toward its outermost planet, our every effort was bent upon overtaking the fleeing Neptunians before us and annihilating them before they could rejoin the main body. At the same colossal speed as ourselves they were fleeing from before us, on toward Neptune's tiny green disk far ahead, and though we held steady in our pursuit after them, we could not lessen the gap between us. Hour passed into hour and day into changeless day thus as we throbbed on in that tremendous pursuit, hours and days that we could not measure, all things seeming timeless now as our great fleet flashed on in this terrific pursuit. At maximum speed, at millions of miles an hour, the Neptunians and ourselves were hurtling on, yet they kept out of reach ahead of us, as Neptune grew larger ahead. And now that mighty pursuit of ours had become so strange and unreal and dream-like that it was as men in a dream that we watched and slept and watched in our space-fliers as Earth's brave fleet shot on through the last reaches of the solar system toward its edge. Timeless indeed seemed the day on day, the hour on hour, of that daring pursuit of our fleeing enemies out from Saturn toward great Neptune, but now we knew that that pursuit had begun to draw to an end, since Neptune's disk was steadily enlarging before us and we had begun slowly to draw closer to the fleeing cylinders! Closer and closer our fleet, our own foremost space-flier, was coming to those fleeing fifteen hundred cylinders, and the interval of hours and days of pursuit out from the wild combat at Saturn seemed as though it had not existed, so tense once more we became as we drew nearer to the Neptunians before us. At last, with Neptune's pale-green disk and the bright little spot of Triton above and behind it within hours of us, we had come so close to the fleeing cylinders that their mass, hurtling on in a cone-like formation, was clearly visible to our unaided eyes in the void ahead. And by this time, in every space-flier of our onrushing fleet, its occupants were waiting impatiently for the moment when we would be near enough to loose our concentrated weapon-rays on the fleeing craft ahead. "We'll overtake them before they reach Neptune!" Marlin declared, gazing intently ahead toward the gleaming points that were the fleeing cylinders far ahead. "Within hours now we'll be up to them!" "Well enough for us that we can do so, too!" Whitely commented. "For if they rejoined their main body, the odds against us might be overpowering!"
