It wasn't until we had covered some two hundred miles of this that something began to loom out of the mist, and I forgot the playboys and the field workers. It loomed higher and higher. Then we burst out into a clearing several miles in diameter, and I saw the structure clearly. It was red, like everything else in this screwy place, and could only have been built out of compressed blocks of the red plant. In shape it was a perfect octagon. It hung poised in the center of the cleared space, suspended on nothing. It had to be at least a mile in diameter, and its sides were pierced with thousands of openings through which its nightmare occupants appeared and disappeared, drifting in and out like they had all the time in the world. I stared until my eyeballs felt paralyzed. Pard was right again. These critters had brains. And my S.S.C. persecutor was right, too. That anti-grav secret was worth more than any string of rocks in the system, including the Killicut Emeralds. Then I swallowed hard. Attaboy was leading me straight across to a window. Closing my helmet, my fingers fumbled badly. My brain was fumbling, too. "Zero hour, chump!" it told me, and I shuddered. Picking up the first hundred pounds of the arsenic, I wobbled over to the airlock. III That palace was like nothing on earth. Naturally, you'll say, it's on Jupiter. But I mean it was even queerer than that. It was like no building on any planet at all. And, in fact, it wasn't on a planet; it was floating up there only two hundred miles in from the raw edge of space. In that building everything stayed right where it was put. If it was put twelve or fifty feet up off the floor, it stayed there. Not that there wasn't gravity. There was plenty of gravity to suit me--just right, in fact--and still they had furniture sitting around in the air as solid as if on a floor. Which was fine for flying hopper-scorps, but what about Casey Ritter, who hadn't cultivated even a feather? Attaboy, however, had the answers for everything. Towing me from the airlock to the window ledge, he again sniffed that delectable odor on my chest, caressed me with his front pair of legs while I manfully endured, and then without warning tossed me onto his back above the little box and flew off with me along a tunnel with luminous red walls. We finally came to the central hall of the palace, and at the sight of all that space dropping away, I clutched at his shell and nearly dropped the arsenic. But he didn't have any brakes I could grab, so he just flew out into mid-air in a room that could have swallowed a city block, skyscrapers and all. It was like a mammoth red cavern, and it glowed like the inside of a red light. No wonder those scorpions like green and purple. What a relief from all that red!
