By degrees my strength and flexibility returned, but my eyes beheld nothing. As I staggered to my feet I peered diligently in every direction, yet met only an ebony blackness as great as that I had known when blindfolded. I tried my legs, blood-encrusted beneath my shredded trousers, and found that I could walk; yet could not decide in what direction to go. Obviously I ought not to walk at random, and perhaps retreat directly from the entrance I sought; so I paused to note the direction of the cold, foetid, natron-scented air-current which I had never ceased to feel. Accepting the point of its source as the possible entrance to the abyss, I strove to keep track of this landmark and to walk consistently toward it.
