The first thing which I saw filled me with amazement. When I described the view from the summit of the great tree, I said that on the farther cliff I could see a number of dark spots, which appeared to be the mouths of caves. Now, as I looked up at the same cliffs, I saw discs of light in every direction, ruddy, clearly-defined patches, like the portholes of a liner in the darkness. For a moment I thought it was the lava-glow from some volcanic action; but this could not be so. Any volcanic action would surely be down in the hollow and not high among the rocks. What, then, was the alternative? It was wonderful, and yet it must surely be. These ruddy spots must be the reflection of fires within the caves⁠—fires which could only be lit by the hand of man. There were human beings, then, upon the plateau. How gloriously my expedition was justified! Here was news indeed for us to bear back with us to London!
