arly defined chimney which led to the top。 If I can once reach that tree； I thought； the battle is won。 The crack was only a few inches wide； large enough to let in an arm and a foot； and it ran slantwise up a perpendicular rock。 I do not think I realized how bad it was till I had gone too far to return。 Then my foot jammed； and I paused for breath with my legs and arms cramping rapidly。 I remember that I looked to the west； and saw through the sweat which kept dropping into my eyes that about half a mile off a piece of cliff which looked unbroken from the foot had a fold in it to the right。 The darkness of the fold showed me that it was a deep； narrow gully。 However； I had no time to think of this； for I was fast in the middle of my confounded crack。 With immense labour I found a chockstone above my head； and managed to force my foot free。 The next few yards were not so difficult； and then I stuck once more。
For the crack suddenly grew shallow as the cliff bulged out above me。 I had almost given up hope； when I saw that about three feet above my head grew the tree。 If I could reach it and swing out I might hope to pull myself up to the ledge on which it grew。 I confess it needed all my courage； for I did not know but that the tree might be loose； and that it and I might go rattling down four hundred feet。 It was my only hope； however； so I set my teeth； and wriggling up a few inches； made a grab at it。 Thank God it held； and with a great effort I pulled my shoulder over the ledge； and breathed freely。
My difficulties were not ended； but the worst was past。 The rest of the gully gave me good and safe climbing； and presently a very limp and weary figure lay on the cliff…top。 It took me many minutes to get back my breath and to conquer the faintness which seized me as soon as the need for exertion was over。
When I scrambled to my feet and looked round； I saw a wonderful prospect。 It was a plateau like the high…veld； only covered with bracken and little bushes like hazels。 Three or four miles off the ground rose； and a shallow vale opened。 But in the foreground； half a mile or so distant； a lake lay gleaming in the sun。
I could scarcely believe my eyes as I ran towards it； and doubts of a mirage haunted me。 But it was no mirage； but a real lake； perhaps three miles in circumference； with bracken… fringed banks； a shore of white pebbles； and clear deep blue water。 I drank my fill； and then stripped and swam in the blessed coolness。 After that I ate some luncheon； and sunned myself on a flat rock。 'I have discovered the source of the Labongo；' I said to myself。 'I will write to the Royal Geographical Society； and they will give me a medal。'
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。
CHAPTER V MR WARDLAW HAS A PREMONITION
A week later the building job was finished； I locked the door of the new store； pocketed the key； and we set out for home。 Sikitola was entrusted with the general care of it； and I knew him well enough to be sure that he would keep his people from doing mischief。 I left my empty wagons to follow at their leisure and rode on； with the result that I arrived at Blaauwildebeestefontein two days before I was looked for。
I stabled my horse； and went round to the back to see Colin。 （I had left him at home in case of fights with native dogs； for he was an ill beast in a crowd。） I found him well and hearty； for Zeeta had been looking after him。 Then some whim seized me to enter the store through my bedroom window。 It was open； and I crawled softly in to find the room fresh and clean from Zeeta's care。 The door was ajar； and； hearing voices； I peeped into the shop。
Japp was sitting on the counter talking in a low voice to a big native … the same 'Mwanga whom I had bundled out unceremoniously。 I noticed that the outer door giving on the road was shut； a most unusual thing in the afternoon。 Japp had some small objects in his hand； and the two were evidently arguing about a price。 I had no intention at first of eaves
