"For it is this great fleet of space-fliers, with Marlin at its head, which alone can halt that doom now! If that fleet can win safely out through the perils of the interplanetary void to Neptune, can win to Triton's sunward side against the opposition of the Neptunians and can destroy the controls and generators of their great sun-ray, can halt that ray, the sun's spin will cease to accelerate and our planet and the other planets will have been saved. But if our fleet cannot do this, if the Neptunians prevent it from reaching the great sun-ray's source, and from halting that ray, then the sun will spin on ever faster and within two-score more days will split at last and engulf in the diverging fires of its two new suns, all the planets save Neptune. For it is this great space-fleet of ours, heading out now toward the last great battle of Earth's and Neptune's races, which alone now can prevent the accelerating speed of the sun and the consequent wrecking of our universe!" CHAPTER XIV An Ambush in Space "Mars ahead and to the left--once more!" As I uttered the words Marlin and Randall and Whitely, beside me, were gazing to the left with me. "Strange," said Randall, "it all seems, almost, as when we first went out past Mars." Strangely similar, indeed, did it seem to all of us, the panorama that now again stretched all about us, visible through the racing space-flier's windows, as we sat in the four control-chairs before them. For ahead and away to the left gleamed again the dull-red disk of Mars, farther now from us than on our first trip out but seeming almost the same. Ahead too, and close to the right, shone mighty Jupiter, and beyond it on the left the yellow spot of Saturn once more, with far beyond it and straight ahead again the green little spark of light that was Neptune. Behind, too, the bluish light-spot of Earth and the lessened fire-disk of the sun were as before, and as before the blazing stars that jeweled all the deep-black firmament about us. But behind our flier we could barely see innumerable tiny gleaming points moving forward at the same speed as ourselves through the void, keeping pace with us in regular formation, a great V-formation of which our flier was the point and that moved steadily on through space. For those tiny points, extending back and out of sight in the void behind us, were the space-fliers of that great fleet of five thousand space-fliers which our own, the flagship, was leading out through the solar system to Neptune!
