"Meanwhile, the once black, bottomless abyss which had suddenly become charged with blinding colors, was changing now to a more solid hue. Green was transplanting the reds and vermilions, and thin, wisp-like rays of yellow that seemed to charge the atmosphere with a super high-tension activity, were twitching nervously in the pit. Gradually the colors merged into a solid mass of luminous green and out of it spun a glistening sphere that appeared to be a ball of the same liquid that was now whirling over the pool!
"The sphere, probably twenty feet in diameter, moved slowly at first, toward the pool, its surface glowing as it revolved with a terrific speed. The atmosphere became stagnant and penetrated deep into the lungs, but Sands and I were too stupefied to move a muscle. I felt a sudden panic seize me and then breaking the grip of stupefaction I ran like a mad man along the edge of the whirling maelstrom. I was struck with fright. You cannot conceive my terror as I stumbled along the pool! I forgot about Sands—forgot about everything in my blind unreasoning. I felt no fatigue as I ran, only stark, mad terror.
"In my wild terrified scramble for safety, I ran past the only exit or entrance down into the crater and soon found myself face to face with the spinning sphere! Bright, swift-moving lights passed around the sphere as it emerged from the abyss. The yellow rays were gone now and as I stared at it in my utter terror, the sphere began to glow like a great emerald ball. The high-pitched scream was more terrific here and it pounded in my ear-drums with a metal-edged sharpness that sent me blind and unreasoning back around the other side of the pool! In my terror I thumped into Sands, who was standing in the same spot where he had been when I started my mad dash. The collision brought us both to the crater floor, clutching for the slightest handhold to prevent us from rolling into the ghastly pool. At the very edge of the pool we came to a stop. Sands put out a hand to brace himself but the tips of his fingers accidentally dipped into the liquid. He jerked back his hand with a bellow. The first digits of his left hand had disappeared, leaving instead, completely healed stumps! The shock of the collision restored my sanity and I helped Sands to his feet.
"We cast quick glances at the sphere. It had moved from the opening of the pit, now lighted brilliantly red, and was whirling at the top of the column in the center of the pool! Gradually the high-pitched scream became a steady hum. The sphere was spinning faster and faster under the whirling pressure of the column. The ball was changing slowly into cylindrical shape, with a sharp-pointed nose and concave butt which gradually thinned out. I stared with unbelief. Surely my brain was playing pranks. I shot a glance at Sands. The old fellow seemed like a statue, immobile as a rock. Insanity was gripping him, I could see, and I screamed.
"Suddenly, the hum of the sphere's rapid whirling motion ceased. Like a bullet shaped projectile it shot into the air, charging it with sparks of pale green lights that drifted back into the pool and settled. We caught a glimpse of the projectile as it leaped from the column. That was all. Immediately it was gone leaving behind only the floating green lights that, even in the radiance of midday, shone brilliantly. The fearful scream of its passing through the atmosphere gradually died away as its distance increased. At my scream Sands had regained control of himself. He placed a palsied hand on my shoulder and stared at me incredulously.
"'Did you see it, pardner?' he asked, completely unnerved.
"'Yes!' I answered, 'I've seen it whatever the thing was!'
"Sands stared at me, mouth agape.
"'Pardner,' he said, 'you look like a ghost! Your face and hands are turning green! Your skin is getting the same color as the stuff in the pool!'
"'You don't look like a white man yourself, Sands,' I managed to jest at him, trying to control my agitation.
