We were now less than thirty feet from the column. Its jeweled sides sparkled and shone before us; looking up, our eyes were dazzled. Something struck the water near me. I glanced to the right and saw what moved me to hasten my stroke and call to Harry to do likewise.
The black devils were increasing the fun by hurling stones at us from the bank—apparently with the kind approval of Pachacamac.
As we neared the column the current which tended to carry us to the right became stronger, but still we seemed not to be approaching the bank. What could it mean? The struggle against it was fast taking our strength.
Looking up, I saw that we had swung round to the other side of the column—it was between us and the alcove. Then I understood. We were in a whirlpool, ever increasing in force, which was carrying us swiftly in a circle from left to right and approaching the column.
I called a swift warning to Harry, who was some ten feet to my left, and he answered that he understood. The stones from the bank were falling thick about us now; one struck me on the shoulder, turning me half round.
The current became swifter—so swift that we were almost helpless against it and were carried around and around the column, which was but a few feet away. And always complete silence.
Nearer and nearer we were carried, till, thrusting out my arm, the tips of my fingers brushed against the side of the column. The water whirled with the rapidity of a mill-stream; ten more seconds and our brains would have been dashed against the unyielding stone. It was now but half an arm's length away. I kept thrusting out my arm in a wild endeavor to avoid it.
Suddenly my outstretched hand found a purchase in a break in the wall, but the force of the water tore it loose and swept me away. But when I reached the same spot again I thrust out both hands, and, finding the edge, held on desperately. The next instant Harry's body was swept against mine, doubling the strain on my fingers.
"The column!" I gasped. "Inside—through the wall—opening—I am holding—"
He understood, and the next moment he, too, had grasped the edge. Together we pulled ourselves, little by little, toward the opening; for our strength was nearly spent, and the force of the maelstrom was nigh irresistible.
