storm that would beat her down among the stones. But there was
no wind, no mist, no storm; and if that was not a miracle--

Several times, to be sure, she missed the trail: once in the second
field of loose stones, before she had become accustomed to the signs;
once on a wide floor of solid rock, where Tuesday slipped and fell,
and she rose a little stunned, and in a brief confusion; and once, the
most alarming of all, when she was for half an hour lost in that
granite wilderness that to Haig had suggested a cemetery of the gods.
But faith sustained her, and her purpose stood in the stead of courage
that might have faltered and even failed. The one moment when
something like despair struck at her heart was that when she found the
bruised and dirty saddle cast aside by the runaway, and thought at
first that it was Philip's; and the one moment of real terror was that
in which, on the summit of the last ridge, she looked back and saw
that dark gray vapors were surging up out of the chasm below the
Devil's Chair.

It chanced that in following the trail from the sharp turn on the last
rock floor to the brink of the cliff (the last pyramid stands some
fifty yards back from it), Marion arrived at about the same distance
to the left of the drop-off as Haig had brought up at the right of
it. From this point even less of the meadow was visible than Haig had
seen at the first view, and the mass of fallen and tumbled granite
appeared even more formidable. Her immediate sensation was of tragic
despair, as the evidence of her eyes for one instant overwhelmed her
faith. But where was Philip? And Sunnysides?

Then a suspicion flashed into her mind. Perhaps she had missed the
trail,--the real trail. She could not have been mistaken in the signs;
there was the last pyramid in plain view still from where she stood.
But it was not unlikely that there was another trail from the sharp
turn where she had been confused for a moment, another exit made
necessary by the disruption of the cliff. She paused uncertainly,
looking now at the great heap of stone below her,--a thousand feet of
jagged rock and sliding sand,--and now back at the toilsome way she
had come. And then her eyes were caught by something that held her
spellbound with horror. Up to the rocky skyline from beyond the
barrier she had lately crossed there swept a tumbling mist, as
gray-black as the rock itself; and an instant after she felt a
stinging blow of wind on her cheek, a
