It is to be noted that much as the Transvaal Republic has benefited from gold-mining, the Boers were at first much averse to it, and threw all the obstacles they could in the way of the miners. And it was this attitude of the Boers, especially towards the Lydenburg pioneers, that led to the next development.
One of the tributaries of the Crocodile River (which flows into Delagoa Bay) is the Kaap River, called also the River of the Little Crocodile, which waters a wide deep valley into which projects the spur of a hill which the Dutch pioneers called De Kaap (the cape). Beyond this cape-like spur the hills rise to a height of three thousand feet, and carry a wide plateau covered with innumerable boulders of fantastic shape--the Duivel's Kantoor. The mists gather in the valley and dash themselves against De Kaap like surf upon a headland; and the face of the hills is broken with caves and galleries as if by the action of the sea, but really by the action of the weather. Upon the high-lying plateau of the Duivel's Kantoor were a number of farms, the chief of which was held by one G. P. Moodie.
One day a Natal trader named Tom M'Laughlin had occasion to cross this plateau in the course of a long trek, and he picked up with curiosity some of the bits of quartz he passed, or kicked aside, on the way. On reaching Natal he showed these to an old Australian miner, who instantly started up-country and found more. The place was rich in gold, and machinery was as quickly as possible got up from Natal, on to Moodie's farm. On this farm was found the famous Pioneer Reef, and Moodie, who at one time would gladly have parted with his farm for a few hundreds, sold his holding to a Natal company for something like a quarter of a million. Then there was a rush of diggers and prospectors back from the Lydenburg district, and the De Kaap 'boom' set in. The beginning was in 1883, and two years later the whole Kaap valley and Kantoor plateau was declared a public gold-field. Two brothers called Barber came up and formed the centre of a settlement, now the town of Barberton. Every new reef sighted or vein discovered was the signal for launching a new company--not now in Natal only, but also in London, to which the gold-fever began to spread (but was checked again by the De Kaap reverses).
