At length I succeeded in reaching the steps and began to climb; keeping close to the wall, on which I observed decorations of the most hideous sort, and relying for safety on the absorbed, ecstatic interest with which the monstrosities watched the foul-breezed aperture and the impious objects of nourishment they had flung on the pavement before it. Though the staircase was huge and steep, fashioned of vast porphyry blocks as if for the feet of a giant, the ascent seemed virtually interminable. Dread of discovery and the pain which renewed exercise had brought to my wounds combined to make that upward crawl a thing of agonizing memory. I had intended, on reaching the landing, to climb immediately onward along whatever upper staircase might mount from there; stopping for no last look at the carrion abominations that pawed and genuflected some seventy or eighty feet below—yet a sudden repetition of that thunderous corpse-gurgle and death-rattle chorus, coming as I had nearly gained the top of the flight and showing by its ceremonial rhythm that it was not an alarm of my discovery, caused me to pause and peer cautiously over the parapet.
