Somewhere beyond I knew that it rose again, but of what value was that to me, since I did not know how great the distance that it maintained a level entirely beneath the surface of the water!

There was but a single forlorn hope, and I took it. Filling my lungs with air, I dived beneath the surface and swam through the inky, icy blackness on and on along the submerged gallery. Time and time again I rose with upstretched hand, only to feel the disappointing rocks close above me.

Not for much longer would my lungs withstand the strain upon them. I felt that I must soon succumb, nor was there any retreating now that I had gone this far. I knew positively that I could never endure to retrace my path now to the point from which I had felt the waters close above my head. Death stared me in the face, nor ever can I recall a time that I so distinctly felt the icy breath from his dead lips upon my brow.

One more frantic effort I made with my fast ebbing strength.

Weakly I rose for the last time--my tortured lungs gasped for the breath that would fill them with a strange and numbing element, but instead I felt the revivifying breath of life-giving air surge through my starving nostrils into my dying lungs. I was saved.
