Mile after mile Tarzan of the Apes put slowly behind him, borne up by sheer force of will where a lesser man would have lain
down to die and rest forever tired muscles whose every move was an agony of effort; but at last his progress became practically mechanical--he staggered on with a dazed mind that reacted numbly to a single urge--on, on, on!
It was strange indeed to see this valley, which had lain
so solitary in the hour of dawn, bristling with arms and dotted with the red coats and breeches.
I reasoned with myself that I had lain
helpless for many hours within the cave, yet nothing had molested me, and my better judgment, when permitted the direction of clear and logical reasoning, convinced me that the noises I had heard must have resulted from purely natural and harmless causes; probably the conformation of the cave was such that a slight breeze had caused the sounds I heard.
