arch of her upper third, occasionally, and scrape it along behind the
comblike row; sometimes a pinnacle stood straight up, like a statuette
of ebony, against that glittering white shield, then seemed to glide out
of it by its own volition and power, and become a dim specter, while the
next pinnacle glided into its place and blotted the spotless disk with
the black exclamation-point of its presence. The top of one pinnacle
took the shapely, clean-cut form of a rabbit's head, in the inkiest
silhouette, while it rested against the moon. The unillumined peaks and
minarets, hovering vague and phantom-like above us while the others
were painfully white and strong with snow and moonlight, made a peculiar
effect.

But when the moon, having passed the line of pinnacles, was hidden
behind the stupendous white swell of Mont Blanc, the masterpiece of the
evening was flung on the canvas. A rich greenish radiance sprang into
the sky from behind the mountain, and in this some airy shreds and
ribbons of vapor floated about, and being flushed with that strange
tint, went waving to and fro like pale green flames. After a while,
radiating bars--vast broadening fan-shaped shadows--grew up and
stretched away to the zenith from behind the mountain. It was a
spectacle to take one's breath, for the wonder of it, and the sublimity.

Indeed, those mighty bars of alternate light and shadow streaming up
from behind that dark and prodigious form and occupying the half of the
dull and opaque heavens, was the most imposing and impressive marvel I
had ever looked upon. There is no simile for it, for nothing is like
it. If a child had asked me what it was, I should have said, "Humble
yourself, in this presence, it is the glory flowing from the hidden head
of the Creator." One falls shorter of the truth than that, sometimes, in
trying to explain mysteries to the little people. I could have found
out the cause of this awe-compelling miracle by inquiring, for it is not
infrequent at Mont Blanc,--but I did not wish to know. We have not the
reverent feeling for the rainbow that a savage has, because we know how
it is made. We have lost as much as we gained by prying into the matter.

We took a walk down street, a block or two, and a place where four
streets met and the principal shops were clustered, found the groups
of men in the roadway thicker than ever--for this was the Exchange of
Chamonix. These men were in the costumes of guides and porters, and
