On each side of us loomed great massed machines at which we merely glanced as we hurried on. As we passed one of the pits that had puzzled me, though, I stepped to its edge, gazed down, then shrank back in horror! For in that shallow, smooth-walled pit there lay what seemed a great pool of thick black liquid unguessably deep, a pool formed by the liquid bodies of hundreds, perhaps thousands, of the liquid comet-creatures that had poured into it! I could glimpse the white eyes floating in it, here and there, but there was no other sign of life or movement in the mass, and as I saw that and thought of the rows upon rows of other similar pits that extended across the comet-city, I understood, and turned swiftly to Jurt Tul. "Sleeping!" I exclaimed. "In their night, their rest-period, they must all pour into these pits together--mingling their liquid bodies!" Swiftly we shrank back from the great pit, moved on toward the clearing. Massed machines, grim and gleaming and towering, loomed all about us, half seen in the crimson dusk, and we passed scores of the great, liquid-filled pits in which slept the comet-creatures, but there was no sign of our two friends. Had they been destroyed? Dread filled me, dread intensified because I realized that soon the comet-creatures would be ending their night, and turning on their white light of day, discovering us there on their world. Then, abruptly, Jurt Tul jerked me back from my forward stride, crouching silently with me upon the street, behind a mass of great mechanisms. For out of the darkness to our right had come the sound of something moving, something approaching us! Silently, tensely, we crouched there, and saw a dark shape moving stealthily down one of the branching streets toward us. It had turned from us, toward the great clearing ahead, when unexpectedly, as we crouched, my arm had brushed against the great machine beside us and touched something that moved beneath the touch, with a loud metallic clicking. Instantly that dark shape ahead had turned, and then was leaping straight toward us! Before we could rise to meet it the rush of it had borne us downward, and as it did so I realized with a wild thrill that it was _not_ a liquid-creature but a great and warm and fur-covered being, many-limbed, that had attacked us! Even as that fact penetrated into my brain our struggle had abruptly ceased, and we were staggering erect, Jurt Tul and I grasping the other. "Gor Han!" I exclaimed. "It's you!" The great Betelgeusan's fur-covered body and strange features were clearly visible to us now as he grasped our own hands, his eyes wide. "Khel Ken! Jurt Tul!" he whispered. "I thought you destroyed in the battle!" "We hid--escaped," I explained to him swiftly. "But you, Gor Han--how have you escaped?--and where's Najus Nar?"
