A Ship's Log looked very similar to a torpedo but was used to measure the speed of a ship. When dragged behind the vessel, movement of water past the propeller caused it to rotate, turning the small needle dials to record the distance and speed travelled. https://museumsvictoria.com.au/immigrationmuseum/resources/journeys-to-australia/Ship's Log Display HeadWalkers Cherub 111 ships lognavigation, speed, knot, chip log, log, thomas walker and son

RMIT University's first ceremonial mace was commissioned by Professor David Beanland, Vice-Chancellor, Royal Melbourne Institute of Technology in 1992, and designed by Ian Wong, a lecturer in Industrial Design. It was the result of a collaborative effort, with staff from industrial design, gold & silversmithing, sculpture, engineering, applied physics, and optical technology working on its production. Materials used include carbon fibre, optical fibres, computer chips, honeycomb aluminium, gold, titanium and crystal. This design drawing shows how the University's distinctive pixel log (that conveys a sense of being at the forefront of technology) was incorporated into the design of the top element of the mace.

The brass wall clock retains its key. It was provided by the Department of Shipping and Transport in about 1900 and is original to the lightstation. It was mounted in the watchroom, a small extension at the front of the lighthouse (later radar station), where lightkeepers completed many of their reports and recorded radio schedules, weather observations, distress calls and other data. Good, reliable clocks were also essential for maintaining a strict roster of hours for winding the clockwork mechanism that kept the lens active. The name of the clock’s manufacturer has not been determined. More specifically it was used for logging radio schedules that were made at five minutes to midday, everyday, and for recording the times of weather observations, distress and any other calls that came in. AMSA notes that ‘Lightkeepers who used this clock were said to have polished and wound it every week while it was in use until the 1990s when its otherwise impeccable time keeping mechanisms finally became inaccurate’.The brass clock at Wilsons Promontory illustrates the importance of timekeeping in a nineteenth century lighthouse. Despite its slightly chipped face, the timepiece has first level contributory significance for its historic association with the watch room and confirmed provenance. The significance of this clock also lies with its complete provenance..1. Brass clock with a circular white face and black roman numerals. Three brackets at back to attach to wall.
