The introduction of the prefabricated blockhouse allowed the swift development of the cross-country security system. Over 50 blockhouses and posts were constructed along a line from Wonderfontein (176km east of Pretoria) to Carolina (40 km to the south), between 30 December 1901 and 17 January 1902.
