"At any rate, we picked our way carefully, shielding our faces, remaining as close to the cave wall as possible, peeping intently into the greenly illuminated circular cavern. Glowing stalactites hung from the cave ceilings in mystic forms. Precious stones and metals in countless numbers cropped out of the lava-like formations. Rock which Sands had accepted previously as cinnabar was red rock-lava bearing iron pyrites and black quartz, containing a wealth of sapphire and diamond-like stones that glittered invitingly under the glare of the green rays cast off by the pool. "'My God, Sands!' I shouted eagerly, forgetting momentarily my sorrows and sympathies for Sands and his sweetheart of long ago. 'We've struck it! This is the real El Dorado! It is like the myths handed down by the Spaniards! Wealth! Riches! Power and--' "'--and unhappiness, greed and all the rest!' Sands added, staring at me curiously. 'It means the fulfillment of your dreams, pardner. You know what it means to me? To me it means the loss of all that I've ever held dear in this life. It means that I've spent my life in quest of happiness--and lost it right here at this pool! Do you realize that, pardner?' "I most certainly did realize it and I calmed down to once again share Sands' great sorrow. He had trailed Allie Lane and her father over the forty-year old trail. Here we believed that it ended forever. No need to search farther. Yet for some unaccountable reason, Sands insisted that she was still alive or if not alive, some remains must exist in that vicinity. "As we continued our search and explorations near the mouth of the cave, the weird, ominous moaning that vaguely portended the advent of something untoward, became audible again. Sands and I stopped in our tracks to listen. Coming from the far side of the pool, the moaning increased gradually until it became a steady wail like the shriek of high-speed machinery. We stood watching the spot which unlike the part of the crater on our side, did not glow with the green luminosity. It seemed to be an inky black pit. Not even a stalactite was visible! "Suddenly as we stared at the spot, the blackness became shot with myriads of colors until it glittered blindingly. The wail was now a terrific shriek. The Manalava Plain seemed to groan under some tremendous impulse emanating from below our feet. The earth swayed and rumbled. From the pool, came a mysterious sputtering and a tiny swirl in its center at first, suddenly became a whirling maelstrom. A thin, silver-like column rose several feet into the air from its middle. Like a miniature water-spout, typical of typhoon infested sections of the South Seas, the rising column whirled faster and faster.
