“Rest awhile here, my lord,” Oros said, bowing to Leo with the reverence that he had shown him from the first, “for this stair is steep and long.  Now we stand upon the Mountain’s topmost lip, and are about to climb that tall looped column which soars above.”

So we sat down in the vault-like place and let the sharp draught of air rushing to and from the passages play upon us, for we were heated with journeying up those close galleries.  As we sat thus I heard a roaring sound and asked Oros what it might be.  He answered that we were very near to the crater of the volcano, and that what we heard through the thickness of the rock was the rushing of its everlasting fires.  Then the ascent commenced.

It was not dangerous though very wearisome, for there were nearly six hundred of those steps.  The climb of the passages had reminded me of that of the gallery of the Great Pyramid drawn out for whole furlongs; that of the pillar was like the ascent of a cathedral spire, or rather of several spires piled one upon another.

Resting from time to time, we dragged ourselves up the steep steps, each of them quite a foot in height, till the pillar was climbed and only the loop remained.  Up it we went also, Oros leading us, and glad was I that the stairway still ran within the substance of the rock, for I could feel the needle’s mighty eye quiver in the rush of the winds which swept about its sides.

At length we saw light before us, and in another twenty steps emerged upon a platform.  As Leo, who went in front of me, walked from the stairway I saw Oros and another priest seize him by the arms, and called to him to ask what they were doing.

“Nothing,” he cried back, “except that this is a dizzy place and they feared lest I should fall.  Mind how you come, Horace,” and he stretched out his hand to me.

Now I was clear of the tunnel, and I believe that had it not been for that hand I should have sunk to the rocky floor, for the sight before me seemed to paralyse my brain.  Nor was this to be wondered at, for I doubt whether the world can show such another.

We stood upon the very apex of the loop, a flat space of rock about eighty yards in length by some thirty in breadth, with the star-strewn sky above us.  To the south, twenty thousand feet or more below, stretched the dim Plain of Kaloon, and to the east and west the snow-clad shoulders of the peak and the broad brown slopes beneath.  To the north was a different sight, and one more awesome.  There, right under us as it seemed, for the pillar bent inwards, lay the vast crater of the volcano, and in the centre of it a wide lake of fire that broke into bubbles and flowers of sudden flame or spouted, writhed and twisted like an angry sea.

From the surface of this lake rose smoke and gases that took fire as they floated upwards, and, mingling together, formed a gigantic sheet of living light.  Right opposite to us burned this sheet and, the flare of it passing through the needle-eye of the pillar under us, sped away in one dazzling beam across the country of Kaloon, across the mountains beyond, till it was lost on the horizon.
