I was tempted myself, but I brought him to his feet, from some impulse I know not what. For what was the use? One spot was as good as another. However, we struggled on.
Another hour and the passage broadened into a clearing. At least so it seemed; the walls abruptly parted to the right and left. And still the impenetrable, maddening darkness and awful silence!
We gave it up; we could go no farther. A few useless minutes we wasted, searching for a soft spot to lie on—moss, reeds, anything. We found none, of course; but even the hard, unyielding rock was grateful to our exhausted bodies. We lay side by side, using our ponchos for pillows; our clothing at least was dry.
I do not know how long I slept, but it seemed to me that I had barely dozed off when I was awakened by something—what?
There was no sound to my strained ears. I sat up, gazing intently into the darkness, shuddering without apparent reason. Then I reflected that nothing is dangerous to a man who faces death, and I laughed aloud—then trembled at the sound of my own voice. Harry was in sound sleep beside me; his regular breathing told of its depth.
Again I lay down, but I could not sleep. Some instinct, long forgotten, quivered within me, telling me that we were no longer alone. And soon my ear justified it.
At first it was not a sound, but the mere shadow of one. It was rhythmic, low, beating like a pulse. What could it be? Again I sat up, listening and peering into the darkness. And this time I was not mistaken—there was a sound, rustling, sibilant.
Little by little it increased, or rather approached, until it sounded but a few feet from me on every side, sinister and menacing. It was the silent, suppressed breathing of something living—whether animal or man—creeping ever nearer.
Then was the darkness doubly horrible. I sat paralyzed with my utter helplessness, though fear, thank Heaven, did not strike me! I could hear no footstep; no sound of any kind but that low, rushing breathing; but it now was certain that whatever the thing was, it was not alone.
From every side I heard it—closer, closer—until finally I felt the hot, fetid breath in my very face. My nerves quivered in disgust, not far from terror.
