They had emerged safely to the upper air with their unfortunate and oft-times troublesome charge. Recognising the impracticability of conveying the latter along the perilous causeway which had taxed their own powers so severely, they had elected to try the other way out, to wit, the vertical shaft, beneath which they had passed shortly after first entering the cavern, and, after a toilsome climb, by no means free from danger, burdened as they were with the unhappy lunatic, had regained the light of day in safety. But their difficulties and dangers were by no means at an end. For the first, they were a long way above the spot where they had left their horses. To regain this would take several hours. It was frightfully rugged and tangled country, and they had but an hour of daylight left. Moreover a tremendous thunderstorm was working up, and one that, judging by the heavy aspect of the clouds, and the brooding sense of oppression in the atmosphere, threatened to last the best part of the night. For the second, they had every reason to believe that these wild and broken fastnesses of bush and rock held the lurking remnants of the Gcaleka bands who were still under arms, and should these discover the presence of intruders, the position of the four men, dismounted, scantily supplied with food, and hampered with their worse than useless charge, would be serious indeed. The latter they still deemed it necessary to keep carefully secured. His transition to the upper air had effected a curious change in him. He was no longer violent. He seemed dazed, utterly subdued. He would blink and shut his eyes, as if the light hurt them. Then he would open them again and stare about him with a gaze of the most utter bewilderment. A curious feature in his demeanour was that the world at large seemed to excite his interest rather than its living inhabitants. In these, as represented by his rescuers, he seemed to evince no interest at all. His gaze would wander past them, as though unaware of their presence, to the broad rugged river-valley, with its soaring _krantzes_ and savage forest-clad depths, as if he had awakened in a new world. And indeed he had. Think of it! Seven or eight months spent in utter darkness; seven or eight months without one glimmer of the blessed light of Heaven; seven or eight months in the very bowels of the earth, in starvation and filth, among living horrors which had turned his brain; the only glint of light, the only sound of the human voice vouchsafed to him being on those occasions when his barbarous tormentors came to taunt him and bring him his miserable food! Small wonder that the free air, the light, and the spreading glories of Nature, had a dazing, subduing effect on the poor lunatic.
