I walked round the lake to look for an outlet. A fine mountain stream came in at the north end, and at the south end, sure enough, a considerable river debauched. My exploring zeal redoubled, and I followed its course in a delirium of expectation. It was a noble stream, clear as crystal, and very unlike the muddy tropical Labongo at Umvelos'. Suddenly, about a quarter of a mile from the lake, the land seemed to grow over it, and with a swirl and a hollow roar, it disappeared into a mighty pot-hole. I walked a few steps on, and from below my feet came the most uncanny rumbling and groaning.
Then I knew what old Coetzee's devil was that howled in the Rooirand.
Had I continued my walk to the edge of the cliff, I might have learned a secret which would have stood me in good stead later. But the descent began to make me anxious, and I retraced my steps to the top of the chimney whence I had come. I was resolved that nothing would make me descend by that awesome crack, so I kept on eastward along the top to look for a better way. I found one about a mile farther on, which, though far from easy, had no special risks save from the appalling looseness of the debris. When I got down at length, I found that it was near sunset. I went to the place I had bidden my native look for me at, but, as I had feared, there was no sign of him. So, making the best of a bad job, I had supper and a pipe, and spent a very chilly night in a hole among the boulders.
I got up at dawn stiff and cold, and ate a few raisins for breakfast. There was no sign of horses, so I resolved to fill up the time in looking for the fold of the cliff which, as I had seen from the horrible crack of yesterday, contained a gully. It was a difficult job, for to get the sidelong view of the cliff I had to scramble through the undergrowth of the slopes again, and even a certain way up the kranzes. At length I got my bearings, and fixed the place by some tall trees in the bush. Then I descended and walked westwards.
Suddenly, as I neared the place, I heard the strangest sound coming from the rocks. It was a deep muffled groaning, so eerie and unearthly that for the moment I stood and shivered.
Then I remembered my river of yesterday. It must be above this place that it descended into the earth, and in the hush of dawn the sound was naturally louder. No wonder old Coetzee had been afraid of devils. It reminded me of the lines in Marmion -
'Diving as if condemned to lave Some demon's subterranean cave, Who, prisoned by enchanter's spell, Shakes the dark rock with groan and yell.'
While I was standing awestruck at the sound, I observed a figure moving towards the cliffs. I was well in cover, so I could not have been noticed. It was a very old man, very tall, but bowed in the shoulders, who was walking slowly with bent head. He could not have been thirty yards from me, so I had a clear view of his face. He was a native, but of a type I had never seen before. A long white beard fell on his breast, and a magnificent kaross of leopard skin covered his shoulders. His face was seamed and lined and shrunken, so that he seemed as old as Time itself.
Very carefully I crept after him, and found myself opposite the fold where the gully was. There was a clear path through the jungle, a path worn smooth by many feet. I followed it through the undergrowth and over the screes till it turned inside the fold of the gully. And then it stopped short. I was in a deep cleft, but in front was a slab of sheer rock. Above, the gully looked darker and deeper, but there was this great slab to pass. I examined the sides, but they were sheer rock with no openings.
Had I had my wits about me, I would have gone back and followed the spoor, noting where it stopped. But the whole thing looked black magic to me; my stomach was empty and my enterprise small. Besides, there was the terrible moaning of the imprisoned river in my ears. I am ashamed to confess it, but I ran from that gully as if the devil and all his angels had been following me. Indeed, I did not slacken till I had put a good mile between me and those uncanny cliffs. After that I set out to foot it back. If the horses would not come to me I must go to them.
I walked twenty-five miles in a vile temper, enraged at my Dutchmen, my natives, and everybody. The truth is, I had been frightened, and my pride was sore about it. It grew very hot, the sand rose and choked me, the mopani trees with their dull green wearied me, the 'Kaffir queens' and jays and rollers which flew about the path seemed to be there to mock me.
About half-way home I found a boy and two horses, and roundly I cursed him. It seemed that my pony had returned right enough, and the boy had been sent to fetch me. He had got half-way before sunset the night before, and there he had stayed. I discovered from him that he was scared to death, and did not dare go any nearer the Rooirand. It was accursed, he said, for it was an abode of devils, and only wizards went near it. I was bound to admit to myself that I could not blame him.
At last I had got on the track of something certain about this mysterious country, and all the way back I wondered if I should have the courage to follow it up.
