I had seen moonlight and daylight together before, but I had not seen daylight and black night elbow to elbow before. At least I had not seen the daylight resting upon an object sufficiently close at hand, before, to make the contrast startling and at war with nature. The daylight passed away. Presently the moon rose up behind some of those sky-piercing fingers or pinnacles of bare rock of which I have spoken--they were a little to the left of the crest of Mont Blanc, and right over our heads--but she couldn't manage to climb high enough toward heaven to get entirely above them. She would show the glittering 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.
