Before Randall, too, to my left, were new controls, the controls of the concentrated force-rays which were to be our fleet's weapons even as such rays were the Neptunians' also, and with which our flagship had of course been equipped. Those controls were two thick metal levers of no great size, with hand-grips at their end, one of which controlled by its position the side of the flier from which the concentrated cleaving ray was shot forth, the other controlling the slant or exact direction at which that ray was emitted. With Randall handling these, our weapons, Whitely had before him all the space-flier's remaining controls--those of the generators, air replenishers, the various recording dials that were vital to its operation, and other essential things. So that as our throbbing flier drove on now at the great fleet's head, with Marlin and Randall and Whitely and myself gazing to the left toward the nearing crimson shield of Mars, we had each before us some vital part of our great fleet's or our flier's control. Gazing toward Mars' red disk, Marlin broke the silence. "We'll need no side-rays this time to hold us out from it," he said, and I nodded. "No, it's far enough from us now, and the speed of our fliers will take them safely past--is taking them past now. But it's the asteroids ahead that I've been thinking of." Marlin somberly shook his head. "There's no help for it, Hunt," he said. "We'll have to lead the fleet straight through the asteroidal belt and trust to chance that as few of our fliers as possible will be struck." The following hours, therefore, were perhaps the most tense and terrible that ever we had experienced. For as we shot on past Mars and through the great belt of whirling asteroids, it was not possible for the five thousand space-fliers of our fleet to maneuver to avoid those asteroids. We must hold straight on in our regular formation, we knew, lest all our fliers crash one into the other, so in that formation we went steadily on through that great zone of death. And hardly had we entered it, Marlin and Randall and Whitely gazing forth as intensely as myself, than an expanding dark globe loomed suddenly before us, sweeping past us with terrifying closeness, and then as it shot past there came suddenly in the blackness of space behind us a soundless flash of fiery light, that flared for a moment and faded. The asteroid, we knew, had struck a flier close behind us!
