thing except themselves! But now, even as we stared in horror and amazement at the vast cone, our ships were driving past it, still over the great clearing filled with close-ranked masses of the half-built ships, until before and beneath us lay the mighty circle's edge. And now we saw that beyond it, touching it, there lay another smaller circle of clear space, amid the vast city's crowding structures of blue light, a circle from which throngs of space-ships were constantly rising and upon which others were descending, it being obviously one of the points of departure and arrival for all ships. Down toward it our own ships were speeding, slower with every moment, until at last they had landed at this smaller circle's edge, our own closest to that edge, the pale-glowing mighty buildings towering up just beside us. Then the space-doors of our ships were clanging open, and their occupants were writhing forth from them. A moment and the door of our prison snapped open; then, herded forward by a half-dozen of serpent-creatures armed with small death-beam tubes, we were marched out of the ship and onto the smooth pavement of blue force that covered this circle also. There, massed together, we were halted for a moment, and took the opportunity to stare about. From the ships behind us, just landed, the last of the serpent-crews had writhed forth, passing across to a narrow street that opened through the mass of towering, shimmering buildings before us, from the circular clearing's edge. We ourselves were being marched toward that street, now, the great oval ships lying empty and deserted behind us, and at sight of their open doors I turned and twitched the arm of Jhul Din, walking beside me. "It's a chance in a million to get away!" I whispered, to him and to Korus Kan. "If we can overpower these guards and get back inside our ship----" They turned toward me, startled, and then as they glanced back toward the deserted ships their eyes lit with excitement. A moment more and I had whispered my plan, glancing toward the half-dozen guards behind us, and then the next moment we put it into effect, Jhul Din suddenly slumping to the blue-force pavement and lying motionless, sprawled as though suddenly stricken down. It was the most primitive of ruses, and I could only hope in that moment that our guards might not have had experience of it. The next moment, though, they had seen the motionless form of the big Spican, and with a natural perplexity had writhed forward toward it, holding their beam-tubes, though, gripped in the coils of their strange bodies, alertly toward ourselves. Beside the big crustacean they halted, tubes trained still upon us as they inspected him. Then the next moment the Spican had reached out his great arms with inconceivable swiftness and suddenness, grasping the serpent-guards beside him before they could turn their tubes down upon him, threshing with them in sudden fierce battle as we rushed forward to aid him.
