"God above!" I heard his swift exclamation; and I observed how, stricken all but speechless, he gaped open-mouthed into the green-lighted vacancy beyond. "God above!" he murmured a second time, before a dumbfounded silence overwhelmed him.
At a bound I had gained his side; and I too, as I gazed in bewilderment before me, seemed to have lost my tongue. "Merciful Heavens!" was all I could mumble in my amazement. "Merciful Heavens, what's this?" And I rubbed my eyes and pinched my sides, to make sure that I was not dreaming.
How shall I describe that stupendous scene which suddenly unfolded before us? Surely, the discoverer of a new planet could not have had a deeper sense of awe and wonder! For it was literally a new world that we beheld. The gallery had ended as if on the brink of a precipice; we were staring down, through yellowish-green abysses, into a chasm as wide and deep as the Grand Canyon of Arizona—as wide and deep, but by no means as irregular—by no means so narrow at the bottom! Unlike the great gorge of the Colorado River, it showed no unevenness of structure; sheer stone walls, straight and precipitous as the walls of a room, shot down beneath us a mile deep; sheer stone walls, equally precipitous and straight, rose opposite us at a distance of more than a mile, and between them spread the bare, level floor of the cavern, which reached to our right and left to an incalculable remoteness.
An unspeakably weird sensation overcame me as I gazed, in the thunderstricken silence, at that tremendous excavation. There was such an atmosphere of unreality about it all that only by degrees did my startled senses absorb the details—the gentle curve of the ceiling, which, arching but a few hundred feet above us, revealed fantastic figures, vaguely man-shaped, that stood out sharply in cameo—the multitude of greenish-yellow bulbs which, square or rounded or elongated into rods and spirals, studded the walls by the thousand and hung in long strings from above—the small round openings like the portholes of a vessel, which dotted the opposite side of the cavern in inestimable myriads, confronting us in scores of horizontal lines, and the little door-like apertures that opened at regular intervals all along the cavern floor.
Long and intently we gazed into that miraculous abyss; many minutes must have passed while we stood there spellbound. It was I that first regained some measure of composure; with a shock, I saw my companion standing entranced, so near the brink of the precipice that I trembled for his safety.
With a hasty gesture, I pulled him back a step. "Better watch out, Phil!" I warned, "else I won't have even your watch to bring back to your mother!"
Like a man in a daze, he wiped a grimy hand over his carrot-colored hair. "Good thing she can't see me now!" he gasped. "Lord preserve me! she'd be offering up prayers for the soul of her poor boy lost in Hell!"
"Lost in Hell is right!" I acknowledged, grimly.
"If I hadn't bit my lips to make sure I was alive, Frank," he continued, with an ugly grimace of his scarred face, "I'd think we had both died and were wandering around somewhere in the devil's back yard!"
