The fifth hour had passed away, when Ayesha said to me, "Lo! the circle is fading; the lamps grow dim. Look now without fear on the space beyond; the eyes that appalled thee are again lost in air, as lightnings that fleet back into cloud."  
I looked up, and the specters had vanished. The sky was tinged with sulphurous hues, the red and the black intermixed. I replenished the lamps and the ring in front, thriftily, heedfully; but when I came to the sixth lamp, not a drop in the vessel that fed them was left. In a vague dismay, I now looked round the half of the wide circle in rear of the two bended figures intent on the caldron. All along that disk the light was already broken, here and there flickering up, here and there dying down; the six lamps in that half of the circle still twinkled, but faintly, as stars shrinking fast from the dawn of day. But it was not the fading shine in that half of the magical ring which daunted my eye and quickened with terror the pulse of my heart; the Bush-land beyond was on fire. From the background of the forest rose the flame and the smoke—the smoke, there, still half smothering the flame. But along the width of the grasses and herbage, between the verge of the forest and the bed of the water creek just below the raised platform from which I beheld the dread conflagration, the fire was advancing—wave upon wave, clear and red against the columns of rock behind; as the rush of a flood through the mists of some Alp crowned with lightnings.
 
Roused from my stun at the first sight of a danger not foreseen by the mind I had steeled against far rarer portents of Nature, I cared no more for the lamps and the circle. Hurrying hack to Ayesha I exclaimed: "The phantoms have gone from the spaces in front; but what incantation or spell can arrest the red march of the foe speeding on in the rear! While we gazed on the caldron of life, behind us, unheeded, behold the Destroyer!"
 
Ayesha looked and made no reply, but, as by involuntary instinct, bowed her majestic head, then rearing it erect, placed herself yet more immediately before the wasted form of the young magician (he still, bending over the caldron, and hearing me not in the absorption and hope of his watch)—placed herself before him, as the bird whose first care is her fledgling.
 
As we two there stood, fronting the deluge of fire, we heard Margrave behind us, murmuring low, "See the bubbles of light, how they sparkle and dance—I shall live, I shall live!" And his words scarcely died in our ears before, crash upon crash, came the fall of the age-long trees in the forest, and nearer, all near us, through the blazing grasses, the hiss of the serpents, the scream of the birds, and the bellow and tramp of the herds plunging wild through the billowy red of their pastures.
 
Ayesha now wound her arms around Margrave, and wrenched him, reluctant and struggling, from his watch over the seething caldron. In rebuke of his angry exclamations, she pointed to the march of the fire, spoke in sorrowful tones a few words in her own language, and then, appealing to me in English, said:
 
"I tell him that, here, the Spirits who oppose us have summoned a foe that is deaf to my voice, and—"
 
"And," exclaimed Margrave, no longer with gasp and effort, but with the swell of a voice which drowned all the discords of terror and of agony sent forth from the Phlegethon burning below—"and this witch, whom I trusted, is a vile slave and impostor, more desiring my death than my life. She thinks that in life I should scorn and forsake her, that in death I should die in her arms! Sorceress, avaunt! Art thou useless and powerless now when I need thee most? Go! Let the world be one funeral pyre! What to ME is the world? My world is my life! Thou knowest that my last hope is here—that all the strength left me this night will die down, like the lamps in the circle, unless the elixir restore it. Bold friend, spurn that sorceress away. Hours yet ere those flames can assail us! A few minutes more, and life to your Lilian and me!"
 
Thus having said, Margrave turned from us, and cast into the caldron the last essence yet left in his empty coffer.
 
Ayesha silently drew her black veil over her face, and turned, with the being she loved, from the terror he scorned, to share in the hope that he cherished.
 
Thus left alone, with my reason disinthralled, disenchanted, I surveyed more calmly the extent of the actual peril with which we were threatened, and the peril seemed less, so surveyed.
 
It is true all the Bush-land behind, almost up to the bed of the creek, was on fire; but the grasses, through which the flame spread so rapidly, ceased at the opposite marge of the creek. Watery pools were still, at intervals, left in the bed of the creek, shining tremulous, like waves of fire, in the glare reflected from the burning land; and even where the water failed, the stony course of the exhausted rivulet was a barrier against the march of the conflagration. Thus, unless the wind, now still, should rise, and waft some sparks to the parched combustible herbage immediately around us, we were saved from the fire, and our work might yet be achieved.
 
I whispered to Ayesha the conclusion to which I came.
 
"Thinkest thou," she answered without raising her mournful head, "that the Agencies of Nature are the movements of chance? The Spi............
