Wandering across my prison roof I looked down into one of the great abysses beneath, a kind of natural courtyard, and beheld there a scene that interested me, and explained the presence of the odor, so often observed. Half a dozen of these gigantic birds were stalking about in this inclosure, and while I looked a man came among them bearing a barrel, the counterpart of the one I possessed. Going to the nearest, he fastened the vessel about its neck, and immediately after it flew up directly past where I stood, and out over the desert. Suddenly it flashed upon me that I might have fallen upon some strange monastery, where the _Fathers_ dispatched birds instead of dogs to rescue those lost upon the plain below. It was merely a thought; I had no way of proving it, and give it for what it is worth. But even the thought was a comfort to my harried soul. Fortunately I had water and food with me, and had no desire to return to the chamber, although momentarily dreading to be summoned before some august power to account for myself. I spent hours in searching the walls below, endeavoring to discover some rift or ledge by which I might descend; but there was not the shadow of a chance upon any side. Exhausted I lay down and slept, but my sleep was troubled, and I soon found myself tramping the bard ground again. I could see nothing but starvation ahead, and imagined the indwellers of the glittering cave beneath quietly awaiting my end; although for what purpose I could not guess.
