At a recent meeting of the Institution of Civil Engineers, the paper read was "On the Diamond Fields and Mines of South Africa," by Mr. James N. Paxman, Asoc. M. Inst. C.E. The author commenced by stating that Kimberley was situated in Griqualand West, above 700 miles northeast from Table Bay, and 450 miles inland from Port Elizabeth and Natal on the east coast. Lines of railway were in course of construction from Table Bay and Port Elizabeth to Kimberley, and were about half completed. In Griqualand there were several diamond mines, the principal of which were Kimberley, De Beer's, Du Toit's Pan, and Bultfontein. In the Orange Free States there were also two mines, viz., Jagersfontein and Koffeyfontein, the first of which produced fine white stones. The mines were all divided into claims, the greatest number of which were to be found in the Du Toit's Pan mine. Bultfontein came next. The deepest and most regularly worked was the Kimberley mine. The next deepest was De Beer's, which, however, was very unevenly worked. Then followed Du Toit's Pan and Bultfontein. The Du Toit's Pan mine ranked next in importance to Kimberley mine. Diamonds were first discovered in 1867 by Mr. O'Reilley, a trader and hunter, who visited a colonist named van Niekirk, residing in Griqua. The first diamond, on being sent to the authorities, was valued at 500l. Considerable excitement was caused throughout the colony, and the natives commenced to look for diamonds, and many were found, among which was one of eighty-three and a half carats, valued at 15,000l. In 1868 many enterprising colonists made their way up the Vaal River, and were successful in finding a good number of diamonds. The center of the river diggings on the Transvaal side was Klipdrift, and on the opposite side Pniel. In all there were fourteen river diggings. Du Toit's Pan and Bultfontein mines were discovered in 1870 at a distance of twenty-four miles from the river diggings. The diggers took possession of these places. Licenses were granted giving the first diggers a right to work. In 1871 De Beer's and Kimberley mines were discovered, and in 1872, Mr. Spalding's great diamond of 282½ carats was found at the river diggings.
