The necessity for laying down a boundary line between Griqualand West and the Orange Free State had arisen from the rival claims of the Chief Waterboer of the Griquas and of President Brand of the Orange Free State to the Diamond Fields. The British Government acquired the rights of the Waterboer, and, after some protracted negotiations, it was arranged that the Orange Free State should abandon its claim on receiving from Griqualand West the sum of 90,000_l._ Mr. de Villiers was the expert nominated by the Orange Free State to be associated with Captain Warren in laying out the boundary. Warren, with two non-commissioned officers of Royal Engineers, arrived at Cape Town towards the end of November, and, after an interview with the Governor, Sir Henry Barkly, proceeded to Port Elizabeth by steamer, and thence by coach, via Graham’s Town and Cradock, to Kimberley, where Major Owen Lanyon, the Administrator, introduced him to his colleague, Mr. Joseph E. de Villiers, Government Surveyor. After an interview with President Brand at Bloemfontein he went into camp outside Kimberley towards the end of December, measured his base, took observations, and elaborated his general scheme of operations. The heat was intense, the shade temperature being over 100° Fahr. for hours together, the atmosphere was highly charged with electricity, and the thunderstorms were often terrific, the lightning playing all round the encampment or party, and the ground being struck in all directions. Mosquitoes and flies were also a great nuisance. The work, however, proceeded satisfactorily and expeditiously, and on 18th April 1877 was completed and ready for inspection. A party composed of the two Commissioners and officials of the two States formally inspected the line from the Vaal to the Orange River, 120 miles, and an official notification of the completion of the work was made to the respective Governments. The plans were then drawn on a scale of three miles to the inch and completed before 15th May. Captain Warren was entertained by President Brand at Bloemfontein to meet the Volksraad at dinner. Votes of thanks from the Legislatures of Griqualand West and the Orange Free State were presented to each of the Commissioners, the former illuminated and very handsomely got up. _Griqualand West Land Claims_
