For a while I kept still. I was utterly squelched. And to think that I had twice protected her from attack—the last time risking my life to save hers. It was incredible that even a daughter of the Stone Age could be so ungrateful—so heartless; but maybe her heart partook of the qualities of her epoch. Presently we found a rift in the cliff which had been widened and extended by the action of the water draining through it from the plateau above. It gave us a rather rough climb to the summit, but finally we stood upon the level mesa which stretched back for several miles to the mountain range. Behind us lay the broad inland sea, curving upward in the horizonless distance to merge into the blue of the sky, so that for all the world it looked as though the sea lapped back to arch completely over us and disappear beyond the distant mountains at our backs—the weird and uncanny aspect of the seascapes of Pellucidar balk description. At our right lay a dense forest, but to the left the country was open and clear to the plateau’s farther verge. It was in this direction that our way led, and we had turned to resume our journey when Dian touched my arm.
