"Yes, in the darkness there, where the Neptunians are sleeping, we'll have a chance to get at one. But we must hurry, for there's little time left before the great signal comes for those on dark and sunward sides to change places!"
So, spurred on by that necessity, we swung ourselves over the wall's edge and then dropped down through the dusk two hundred feet toward the ante-room compartment's floor. Yet that great drop was to us not more than a drop of a tenth that distance on Earth, so slowly did we float down toward the floor, breaking our fall a little by scraping along the smooth wall. We struck the floor, tumbled in a heap there, and then straightened, gazed about. The ante-room was quite empty and in it were but three of the broad low doors. One led back to the cell-compartments from which we had escaped, another led to the sunward side. Through that had just passed the Council of Thirty and their guards. The other led into the great circular Council compartment itself. The last, it was clear, was the only one that held out to us any prospect of reaching the dark side, so we passed through it quickly and into the great Council compartment, moving now in great floating leaps each step.
The great circular compartment was as empty of life as the one which we had just left, the twilight dusk in it dispelled somewhat by the soft-glowing disks in its walls. The great ring-table in it had in the seats around it no Neptunians of the Council now, but at that table's center stood still the great metal globe whose strange mechanism made of the thirty minds of the Council members a single mind, in perception and action. Knowing even as we did that it was but a lifeless mechanism now, without the Council's members connected to it, it was yet with some awe that we stared toward that great mechanism, to whose voice we had listened so short a time before. Much would I have given to have examined it, to have inspected whatever strange mechanism lay within the globe, but time now was our enemy. Soon the signal would come that would send the millions of Neptunians on dark and sunward sides streaming across Triton to change their sides. And unless we could steal one of the cylinders and escape before that signal came, we would inevitably be discovered.
So, sparing only a glance toward the great silent globe, Marlin and I moved silently across the great Council compartment, toward one of the low doors in it that led apparently toward the dark side of Triton, to our right. Cautiously we passed through that door, finding ourselves in another ante-room compartment, as empty now as the one through which we had already come. Swiftly we moved across it, in the great floating leaps that each step of ours made now, toward the door in it that led in the direction of the dark side. But even as we moved toward that door, as we stooped to pass through it, Marlin and I shrank suddenly back, appalled. For as we bent toward that door, the sound of staccato voices had come to us from just ahead, and we had seen in that moment that there were Neptunians in the next compartment, several armed with ray-tubes, who were coming straight toward that door, straight toward us!
A moment we glanced wildly about through the dusky compartment as they came toward us, then we had leaped aside from the door, had reached one of the compartment's corners, leaping more than a score of feet toward that corner and crouching there in the dusk, even as the dozen Neptunians came through the door! It was our one chance of escaping them, the chance that they might not perceive us in the compartment's corner through the twilight dusk that reigned in it. But I knew that so keen were their great bulging multiple eyes that it was against hope that I hoped. The Neptunians who had come into the compartment, however, seemed not to notice us as they entered, passing across it toward the great Council compartment, conversing among themselves in their snapping speech-sounds as they did so. Tensely we crouched there, stiffening suddenly, as we saw one of the disk-bodied monsters suddenly turn and glance back across the compartment in our direction. But in the next moment he had turned back, not seeing us, and then they had passed through the opposite door, their strange voices passing from our hearing.
Marlin and I straightened, with long breaths of relief. "Close, Hunt!" he whispered. "But on to the dark side—we've little enough time left!"
"We're almost out of the twilight band now," I told him, "and in the dark side we'll be a little safer."
And now we were moving quietly through the door from which the approach of the Neptunians had startled us, through the compartment beyond it and on through another and another. These compartments of the twilight band seemed for the most part quite empty, filled neither with masses of working Neptunians like those of the sunward side, nor masses of sleeping Neptunians like those of the dark side. We had found, however, that the compartments of the twilight band were in fact used only for the housing of the Council of Thirty and of the other activities and departments of the rulers of the Neptunians, their only purpose aside from that being to provide easy access from the dark to the sunward side of Triton, and vice versa. So it was that now as we crept through the twilight dusk of those compartments, we found them almost wholly empty and tenantless, though once or twice we were forced again to seek hiding in the shadows as we heard the staccato voices of Neptunians in the distance. Once, too, we were startled by one of the cylinders throbbing by close above us, and since we had had no time to hide from it, thought ourselves discovered by it, though after tense minutes it became plain that its occupants had not seen us.
But soon the twilight of that narrow band was deepening, and almost at once, it seemed, we were moving from that twilight dusk into a deep darkness that obscured all things about us. We had reached the dark side of Triton, we knew, and now moved more carefully still, for upon that dark side, we knew equally well, slept half the massed millions of the Neptunian races. The first few compartments which we traversed in that darkness, however, were as empty as those in the twilight behind us. But then, as we moved silently on, we came into the first of the great sleeping-compartments. Even like those which had puzzled us so on Neptune it was, with its towering walls lined with intersecting shelves whose openings, twice as long as they were high, were ranged in rows, one above the other, like giant pigeon-holes.
