"Stagnation—everything stinking and stale! The cavern smelled of sheer funk. It curled our nostrils and nauseated our stomachs to such an extent that I became violently ill temporarily.
"'Let's get out of here, Sands!' I whispered. 'I think we are headed into the cave and if we turn around we can reach the opening.'
"'We can try it. I'd like to get a breath of air.'
"'Hold on to me then,' I said, 'we'll get out!'
"'Maybe!'
"With Sands holding onto my arm we turned around and began a slow, deliberate walk back to what we thought was the entrance of the cave, long since dark. For perhaps fifteen minutes we picked our way along the cave not knowing what step might sink us into death.
"Suddenly I collided with a solid wall. Around the edges the sunlight of the outer world flickered and I knew that it was the entrance to the cave.
"We were stunned when we discovered that the entrance had been closed solidly with massive slabs of rock! The air was less heavy and stagnant here and we sat down after a strenuous effort to roll back the rock wall that trapped us. We rested, motionless on the floor of the cave. I could not see Sands but sounds of his heavy, even breathing came to me. We were too exhausted even to speak but I suddenly felt the pangs of hunger.
"I slipped my pack from my shoulders and felt within it. I handed Sands several squares of hardtack and a bar of chocolate for which he mumbled his thanks. Ravenously I devoured my ration; then got out my carbide lamp and toyed with it.
"As I sat I noticed that the low moaning sounds that we had previously heard were again issuing from deep within the cave. I shuddered. The sounds beat terrifically on my brain and in my terror I drew my gun and fired four shots rapidly toward the interior.
