Towards a legal history of white women in the Transvaal, 1877-1899
… a background for studying white women in the Transvaal between 1877 and 1899. Legal documents are used as primary sources, as they are invaluable for researching women’s history, in that they provide a new perspective. When writing women’s history, it must be grounded in theory, as, especially …

Pretoria heritage layers : developing a heritage catalogue for iron age settlements found in the (former) Transvaal
… list of Iron Age settlements found in the Transvaal will be established. These sites will be interpreted through the use of a heritage value matrix to determine their cultural significance. Thereafter the sites will be added to data sheets that can be used as the beginning of a concise …

Technological change and employment in South African agriculture : the case of maize harvesting in the Western Transvaal
… in six magisterial districts of the Western Transvaal for the period 1968-1981. In 1968 about 30 percent of the crop was being harvested mechanically; by 1981, 95 percent. Sacks, in which almost half of total output was being delivered to depots in 1968, had, by 1977, been almost completely …

Impact on soil chemistry of atmospheric sulfur fallout near Arnot coal-fired power station, in the Eastern Transvaal highveld region, South Africa
The objective of the study was to evaluate the potential impact of atmospheric sulfur deposition on the soils surrounding Arnot power station. In particular, the study focused on the relationship between sulfur and organic carbon (OC) and on the various pools of sulfur in the soil. A representative …
