The silver wavy bars on the lower section of the shield represent the Vaal and Limpopo rivers which form the northern and southern borders of the Witwatersrand gold fields. Above the shield is the head of a Kudu, an antelope typical of the Witwatersrand and the university's mascot. The university's motto, "Scientia et Labore", meaning "Through Knowledge and Work" in Latin, appears just below the shield. The university's coat of arms evolved from the badge of the South African School of Mines. This badge consisted of a diamond with a shield superimposed upon it. A prospector's pick and a sledge hammer overlaid with broken ore and a mill appeared on the shield. The South African School of Mine's motto was the same as the university's current one, and surrounded the shield. Governance and administration As set out in the Higher Education Act (Act No. 101 of 1997) and in the Statute of the University of the Witwatersrand, the university is governed by Council. The Chancellor of the university is the ceremonial head of the university who, in the name of the university, confers all degrees. The positions of Principal and Vice-Chancellor are merged, with the Vice-Chancellor responsible for the day-to-day running of the university and accountable to Council. Council is responsible for the selection of all Vice-Chancellors, Deputy Vice-Chancellors and Deans of Faculty. The responsibility for regulating all teaching, research and academic functions of the university falls on Senate. Additionally, the interests of the university's students are represented by the Students' Representative Council (SRC), which also selects representatives to Senate and Council. Campuses The university is divided into five academic campuses, the main administrative campus is East Campus. Across the De Villiers Graaff Motorway lies West Campus. The two are joined by a brick-paved walkway across the highway called the Amic Deck. East and West Campus effectively form a single campus, bordered by Empire Road to the north, Jan Smuts Avenue to the east, Jorrissen Street and Enoch Sontonga Road to the south and Annet Road to the west. The historic East Campus is primarily the home of the faculties of Science and Humanities, as well as the University Council, Senate and management. West Campus houses the faculties of Engineering and the Built Environment, and Commerce, Law and Management. East Campus is home to four residences, namely Men's Res (male), Sunnyside (female), International House (mixed) and Jubilee Hall (female). West
