Then the soil became meagre, with great patches of bare rock cropping out, and now and then the nest of a condor in a crevice. Finally there was nothing at all but the bare rock, and had it not been very rough and weathered, he could scarcely have ascended farther. Knobs, ledges, and pinnacles, however, helped greatly; and it was cheering to see occasionally the sign of some lava-gatherer scratched clumsily in the friable stone, and know that wholesome human creatures had been there before him. After a certain height the presence of man was further shewn by handholds and footholds hewn where they were needed, and by little quarries and excavations where some choice vein or stream of lava had been found. In one place a narrow ledge had been chopped artificially to an especially rich deposit far to the right of the main line of ascent. Once or twice Carter dared to look around, and was almost stunned by the spread of landscape below. All the island betwixt him and the coast lay open to his sight, with Baharna's stone terraces and the smoke of its chimneys mystical in the distance. And beyond that the illimitable Southern Sea with all its curious secrets.
