At that place the upper third of one or two majestic purple domes projected above our level on either hand and gave us a sense of a hidden great deep of mountains and plains and valleys down about their bases which we fancied we might see if we could step to the edge and look over.

These Sultans of the fastnesses were turbaned with tumbled volumes of cloud, which shredded away from time to time and drifted off fringed and torn, trailing their continents of shadow after them; and catching presently on an intercepting peak, wrapped it about and brooded there -- then shredded away again and left the purple peak, as they had left the purple domes, downy and white with new-laid snow.

In passing, these monstrous rags of cloud hung low and swept along right over the spectator's head, swinging their tatters so nearly in his face that his impulse was to shrink when they came closet.

In the one place I speak of, one could look below him upon a world of diminishing crags and canyons leading down, down, and away to a vague plain with a thread in it which was a road, and bunches of feathers in it which were trees,--a pretty picture sleeping in the sunlight--but with a darkness stealing over it and glooming its features deeper and deeper under the frown of a coming storm; and then, while no film or shadow marred the noon brightness of his high perch, he could watch the tempest break forth down there and see the lightnings leap from crag to crag and the sheeted rain drive along the canyon-sides, and hear the thunders peal and crash and roar.

We had this spectacle; a familiar one to many, but to us a novelty.
We bowled along cheerily, and presently, at the very summit (though it had been all summit to us, and all equally level, for half an hour or more), we came to a spring which spent its water through two outlets and sent it in opposite directions.
