fidgeting and looking over his shoulder at my ship, so I eased in the controls and edge after him. To my surprise a vapor shot out of a box that I had taken for a natural lump on his back, and he darted away from me. I opened the throttle and tore after him among the immense red blobs that were now beginning to be patterned with dozens of green-and-purple scorpions, all busy filling huge baskets with buds and tendrils, no doubt.

Other scorpions oared and floated about in twos and threes in a free and peaceable manner that almost made me forget that I was scared to death of them, and they stared at my boat with only a mild interest that would have taught manners to most of my fellow citizens of Earth.

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.

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.

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
