up to it. And now it came to my steadying brain that
there was something puzzling, peculiar, strangely unfamiliar about
this light. It was silvery, shaded faintly with a delicate blue and
flushed lightly with a nacreous rose; but a rose that differed from
that of the terraces of the Pool Chamber as the rose within the opal
differs from that within the pearl. In it were tiny, gleaming points
like the motes in a sunbeam, but sparkling white like the dust of
diamonds, and with a quality of vibrant vitality; they were as though
they were alive. The light cast no shadows!

A little breeze came through the oval and played about us. It was
laden with what seemed the mingled breath of spice flowers and pines.
It was curiously vivifying, and in it the diamonded atoms of light
shook and danced.

I stepped out of the car, the Russian following, and began to ascend
the curved steps toward the opening, at the top of which O'Keefe and
Olaf already stood. As they looked out I saw both their faces
change--Olaf's with awe, O'Keefe's with incredulous amaze. I hurried
to their side.

At first all that I could see was space--a space filled with the same
coruscating effulgence that pulsed about me. I glanced upward, obeying

the azure above the day-world seems to fill all the heavens--through
it ran pulsing waves and flashing javelin rays that were like shining
shadows of the aurora; echoes, octaves lower, of those brilliant
arpeggios and chords that play about the poles. My eyes fell beneath
its splendour; I stared outward.

Miles away, gigantic luminous cliffs sprang sheer from the limits of a
lake whose waters were of milky opalescence. It was from these cliffs
that the spangled radiance came, shimmering out from all their
lustrous surfaces. To left and to right, as far as the eye could see,
they stretched--and they vanished in the auroral nebulosity on high!

"Look at that!" exclaimed Larry. I followed his pointing finger. On
the face of the shining wall, stretched between two colossal columns,
hung an incredible veil; prismatic, gleaming with all the colours of
the spectrum. It was like a web of rainbows woven by the fingers of
the daughters of the Jinn. In front of it and a little at each side
was a semi-circular pier,
