I saw that the four disk-bodied Neptunians who sat about us and guarded us were indeed watching us closely now with their strange bulging eyes, so gave over for the moment our whispered conversation, though with a slight gleam of hope. Glancing back again toward the great force-ray that was almost invisible behind us as the eleven cylinders raced on around Triton's metal surface, I was aware that Marlin was staring back toward it also, intently, shaking his head a little, as though puzzled by something concerning that giant beam of force. In a moment he turned his attention ahead. Our cylinders now were flashing around Triton from its sunward side to its dark side, and as we rushed on Marlin and I could see that to all appearances Triton was not rotating, or at least not above a low rate of speed. Then as we entered into the deeper shadow of the dark side, the sun's little disk vanishing behind us as we shot around Triton's curving surface into the shadow, Marlin uttered a low exclamation once more, and as I turned to look in the same direction I saw that far ahead there was stabbing out and upward into the black void of outer space a second giant force-ray like that one we had already seen shooting toward the sun! Stupefied, I gazed toward it. For the first giant force-ray, amazing as it was, had yet been expected by us, more or less, since we had known from the first that such a colossal force-beam was stabbing from the region of Neptune toward the sun. But this second mighty force-ray, which seemed exactly the same in size and appearance and which rose from a giant pit or well in the vast metal roof even as did the first, was not directed toward the sun. For it was on the other side of Triton from the first ray, was exactly half around Triton from the first and was going out into space in an exactly opposite direction! Thus while the first colossal force-ray, springing out from Triton's sunward side, shot straight toward the sun, this second huge force-ray, on Triton's dark or outer side, was radiating straight out into the vast void of interstellar space, was radiating straight out, to all appearances, toward the unthinkably distant stars of Sagittarius that burned in that mighty void!
