The cut strands floated in the air until borne down by the weight of the approaching spiders, who followed to the severed ends but no further. Here they either hung glaring at us or else clambered up and down excitedly, but not one of them ever ventured from his strand. As I watched them, their antics suggested a plan. "They are helpless when their web is severed," I said to Nur An. "Therefore if we cut all their webs they cannot reach us." Whereupon, advancing, I swung my long sword above my head and cut downward through the remaining strands. Instantly the creatures set up their infernal screaming. Several of them, torn from their webs by the blow of my sword, lay upon the ground upon their bellies, their feet sticking straight up into the air. They seemed utterly helpless, and though they screamed loudly and frantically waved their legs, they were clearly unable to move; nor could those hanging at either side of the trail reach us. With my sword I destroyed those that lay in the path and then, followed by Nur An, I entered the forest. I turned about to have a last look at the discomfited insects to see what they might be about. They had stopped screaming now and were slowly returning into the foliage, evidently to their lairs, and as they seemed to offer no further menace we continued upon our way. The trees and bushes along the pathway were innocent of fruit or berries, though just beyond reach we saw them growing in profusion, behind a barrier of those gossamer webs that we had so quickly learned to avoid. "This trail appears to have been made by man," said Nur An. "Whoever made it, or when," I said, "there is no doubt but that some creature still uses it. The absence of fruit along it would alone be ample proof of that." We moved cautiously along the winding trail, not knowing at what moment we might be confronted by some new menace in the form of man or beast. Presently we saw ahead of us what appeared to be an opening in the forest and a moment later we emerged into a clearing. Looming in front of us at a distance of perhaps less than a haad was a towering pile of masonry. It was a gloomy pile, apparently built of black volcanic rock. For some thirty feet above the ground there was a blank wall, pierced by but a single opening--a small doorway almost directly in front of us. This part of the structure appeared to be a wall, beyond it rose buildings of weird and grotesque outlines and dominating all was a lofty tower, from the summit of which a wisp of smoke curled upward into the quiet air.
