My hand easily reached the top, and, grasping the slippery surface with a grip made firm by despair, and concentrating every ounce of strength in one final effort, I drew myself out of the water and fell completely exhausted on the ground.

Under such circumstances time has no place in a man's calculations; he is satisfied to breathe. I believe that I lay barely conscious for several hours, but it may have been merely as many minutes. Then I felt life stir within me; I stretched my arms and legs and sat up. Gradually entered my mind the thought of Desiree and Harry and the Andes above and Felipe shuddering with terror as he flew from the cave of the devil.

First came Harry; but hope did not enter. It was inconceivable that he, too, should have escaped that fearful torrent; stupendous luck alone had saved me from being dashed senseless against the rocks and guided me to the ledge on which I rested.

Then he was gone! I had no thought of my own peril. I had gone through the world with but little regard for what it held; nothing had been sacred to me; no affection had been more than a day's caprice; I had merely sucked amusement from its bitter fruit.

But I loved Harry; I realized it with something like astonishment. He was dear to me; a keen, intense pain contracted my chest at the thought of having lost him; tears filled my eyes; and I raised up my voice and sang out wildly:

"Harry! Harry, lad! Harry!"

The cavern resounded. The call went from wall to wall, then back again, floating through black space with a curious tremor, and finally died away in some dim, unseen corridor. And then—then came an answering call!

Owing to the conflicting echoes of the cavern, the tone could not be recognized. But the word was unmistakable; it was "Paul."

I sprang to my feet with a shout, then stood listening. Out of the blackness surrounding me came the words, in Harry's voice, much lower, but distinct:

"Paul! Paul, where are you?"
