It was as I had thought. The base of the column consisted merely of two massive pillars, some twelve feet in length and circular in shape. The water rushed in through each of the two openings thus left, and inside of the column was the center of the whirlpool, sucking the water from both sides. The water I had seen; I had not counted on the whirlpool.

We had pulled ourselves round till our bodies rested against the edge of the opening, clinging to either side. Inside all was blackness, but we could judge of the fury of the maelstrom by the force of the current outside. Stones hurled by the Incas were striking against the sides of the column and in the water near us.

We were being hunted from life like dogs, and a hot, unreasoning anger surged through my brain—anger at the grinning savages on the bank, at the whirling black water, at Harry, at myself.

Whichever way we looked was death, and none worth choosing.

"I can't hold—much longer," Harry gasped. "What's the use—old man—Paul—come—I'm going—"

He disappeared into the black, furious whirlpool with that word. The next instant my own fingers were torn from their hold by a sudden jerk of the water, and I followed.
