“Ariseep, who it seems, in the years he had been there, had explored every nook and cranny of the valley, knew at once what he meant, and quickly pointed out to us, not a hundred paces away, a dense and prickly mass of cactus and euphorbia bush; here, after half an hour’s hewing and slashing with our hunting knives, we managed to open a pathway, and at last a cave-like opening in the mountain, about seven feet in diameter, lay before us. Grandfather Ariseep, questioned as to the tunnel, said that, upon first discovering it, which he had done quite by accident while hunting rock-rabbits, he had once been through, years before, but, as he had found the passage long and dangerous, and the valley beyond appeared to him less interesting than his present abiding place, he had never repeated the journey. However, he gave us warning that snakes abounded and might not impossibly be encountered in the twenty minutes’ crawl, which, as Klaas had told me, it would take to get through.

“This opinion, translated by Klaas, was not of a nature to fortify me in the undertaking, yet, rather than leave the diamonds unexplored, I felt prepared to brave the terrors of this uncanny passage.

“It was now three o’clock; the sun was marching steadily across the brassy firmament on his westward trek and we had no time to lose.

“‘In you go, Klaas,’ said I, and, nothing loth, Klaas dived into the bowels of the mountain, I at his heels. For five minutes, by dint of stooping and an occasional hands-and-knees creep upon the flooring of the tunnel, sometimes on smooth sand, sometimes over protruding rock and rough gravel, we got along very comfortably. Then the roof of the dark avenue—for it was pitch dark now—suddenly lowered, and we had to crawl along, especially I, as being taller and bulkier than Klaas, like serpents, upon our bellies. It was unpleasant, deuced unpleasant, I can tell you, boxed up like this beneath the heart of the mountain. The very thought seemed to make the oppression a million times more oppressive. It seemed that the frightful pile of rock, towering far above us, was bodily descending to crush us into a horrible and hidden tomb. The thought of lying here, squeezed down till Judgment Day, was appalling; or, perhaps, more mercifully one’s bones might, ages hereafter, be discovered as these regions became settled up, in much the same state in which mummified cats are occasionally found in old chimneys and hidden closets when ancient dwellings are pulled down in England. Even Klaas, plucky Bushman though he was, didn’t seem to relish the adventure and spoke in a subdued and awe-stricken whisper. Sometimes since, as I have thought of that most gruesome passage, I have burst into a sweat nearly as profuse, though not so painful, as I endured that day. At last, after what seemed to me hours upon hours of this painful crawling and Egyptian gloom, we met a breath of fresher air; the tunnel widened and heightened, and in another five minutes we emerged into the blessed sunlight. Little Klaas looked pretty well ‘baked,’ even in his old leather ‘crackers’ and flannel shirt; as for myself, I was literally streaming, every thread on me was as wet as if I had plunged into a river. We lay panting for awhile upon the scorching rocks, and then sat up and looked about us.

“If the Paarl Kloof, as Klaas called it, from whence we had just come, had been sufficiently striking, the mighty amphitheatre in which we lay was infinitely more amazing. Imagine a vast arena, almost completely circular in shape, flat and smooth, and composed as to its flooring of intermingled sand and gravel, reddish-yellow in colour. This arena was surrounded by stupendous walls of the same ruddy brown rock we had noticed in Paarl Kloof, which here towered to a height of close on a thousand feet. An inspection of these cliffs, which sheered inwards from top to bottom, revealed the fact previously imparted to me by Klaas, that no living being could ever penetrate hither save by the tunnel passage through which we had come. The amphitheatre, which here and there bore upon its surface a thin and scattered covering of bush and undergrowth, seemed everywhere about half-a-mile across from wall to wall. In the centre of the red cliffs, blazing forth in splendour, ran a broad band of the most glorious opalescent rock-crystal, which flashed out its glorious rays of coloured light as if to meet the fiery kisses of the sun. This flaming girdle of crystal, more beautiful a thousand times than the most gorgeous opal, the sheen of a fresh-caught mackerel, or the most radiant mother-of-pearl, I can only compare in splendour to the flashing rainbows formed over the foaming falls of the Zambesi, which I have seen more than once. It ran horizontally and very evenly round at least two-thirds of the cliff-belt that encircled us. It was a wonderful and amazing spectacle, and I think quite the most singular of the many strange things (and they are not few) I have seen in the African interior.

“Well, we sat gazing at this crystal rainbow for many minutes, till I had somewhat feasted my enraptured gaze; then we got up and at once began the search for diamonds. Directly I saw the gravel, especially where it had been cleansed in the shallow spruits and dongas by the action of rain and flood, I knew at once we should find ‘stones’; it resembled almost exactly the gravel found in the Vaal River diggings, and was here and there strongly ferruginous, mingled with red sand and occasionally lime.

“I noticed quickly that agates, jaspers and chalcedony were distributed pretty thickly, and that occasionally the curious banddoom stone, so often found in the Vaal River with diamonds, and, indeed, often considered by diggers as a sure indicator of ‘stones’ was to be met with. In many places the pebbles were washed perfectly clean and lay thickly piled in hollow water-ways; here we speedily found a rich harvest of the precious gems. In a feverish search of an hour and a half, Klaas and I picked up twenty-three fine stones, ranging in size from a small pigeon’s egg to a third of the size of my little finger nail. They were all fine diamonds, some few, it is true, yellow or straw-coloured, others of purest water, as I afterwards learned, and we had no difficulty in finding them, although we wandered over not a twentieth part of the valley. I could see at once from this off-hand search that enormous wealth lay spread here upon the surface of the earth; beneath probably was contained fabulous wealth. I was puzzled at the time, and I have never had inclination or opportunity to solve the mystery since, to account for the presence of diamonds in such profusion. Whether they were swept into the valley by early floodings of the Orange River through some aperture that existed formerly, but had been closed by volcanic action, or whether, as I am inclined to think, the whole amphitheatre is a vast upheaval from subterraneous fires of a bygone period, is to this hour an unfathomed secret. I rather incline to the latter theory, and believe that, like the Kimberley ‘pipe,’ as diggers call it, the diamondiferous earth had been shot upwards funnel-wise from below, and that ages of floods and rain-washing had cleansed and left bare the gravel and stones upon the surface.

“From the search we had had, I made no doubt that a fortnight’s careful hunting in this valley would make me a millionaire, or something very like it. At length I was satisfied, and as the westering sun was fast stooping to his couch, with a light heart and elastic step I turned with Klaas to depart. The excitement of the ‘find’ had quite banished the remembrance of that awful tunnel passage so recently encountered.

“‘We’ll go back now, Klaas,’ said I, ‘sleep in your grandfather’s kraal, and get to the waggon first thing in the morning; then I shall arrange to return and camp a fortnight in Paarl Kloof, leaving the waggon at the pool. In that time we shall be able to pick up diamonds enough to enrich ourselves and all belonging to us for generations. I don’t mind then who discovers the valley; they can make another Kimberley of it if they choose, for aught I care.’

“At half-past five we again entered the tunnel. It was a nasty business when one thought of it again, but it would soon be over. As it flashed across my brain, I thought at the moment that two such journeys a day for six or seven days would be quite as much as even the greediest diamond lover could stomach. As before, Klaas went first, and for half the distance all went well. Suddenly, as we came to a sandy part of the tunnel, there was a scuffle in front, a fierce exclamation in Bushman language, and then Klaas called out in a hoarse voice, ‘Allemaghte, sieur, een slang het mij gebissen!’” (Almighty, sir, a snake has bitten me!)
