Taken between circa 1920 - 1950 this photograph depicts a man dressed in dark trousers, a white long sleeved shirt and broad-brimmed workers hat digging around in the Three Mile Mine at Barramutha. The mine was an important gold resource and was typically mined using a method known as hydraulic sluicing whereby high powered water jets are used to dislodge rock or move sediment. The remaining water sediment slurry is directed through sluice boxes to remove the gold. The Beechworth mining district was one of six mining districts established by the governor-in-council on 4th of January 1858 under the provisions of An Act for Amending the Laws Relating to the Goldfields (21 Vic no. 32). This photograph shows historic and research value into the historical methods of hydraulic sluicing in the Beechworth mining disctrict. It also shows the evolution of the mining methods and has potential for understanding future engineering endeavors in the context of victorian mine goldfields.

This report lists the depths of water and the consistency of the seabed surrounding the Warrnambool Harbour in October 1929, The information, often referred to as 'soundings', was obtained by Jet Probing,. In earlier days a lead line was used to perform a similar task. The author of the document is unknown. Jet Probing is a method used for underwater archaeology, cable installation and coastal engineering. A jet probe is a machine that produces a strong jet of water that penetrates the layers of sediment on the seabed, determining their depth, thickness and consistency. It provides a survey of the seabed and can be used as an aid to engineering design and construction. The report mentions lining up with the wooden jetty, the end of the breakwater and the leading lights. It mentions sand, loose rock and rock. It tells of stopping work due to the water being too rough, the pipe choking, difficulty in connecting pipes, and pipe joint breaking as it tried to get through the sand, The report in the document is significant for its connection with the Warrnambool Harbour, Warrnambool Breakwater, Warrnambool Jetty and Lady Bay. The report gives figures for the depth and consistency of the water and seabed at a particular point in time and can be used to compart with similar figures taken at different times. The results could determine plans for future engineering works.Report, titled 'Jet Probings, Warrnambool Harbour'. Two pages of cream coloured paper with hand written notes in pen and ink. Report covers three days of Jet Probings, with resulting figures and comments, for the depths of the surroundings of the Warrnambool Harbour. The report is in point form, with some underlining. Dates of recordings are 14-10-29, 15-10-29 and 16-10-29. (1929) The situation of the harbour had become a real problem by 1910 and required continuous dredging. In 1914 the Breakwater was extended but proved to be a failure because the work began to subside and by 1920 about two thirds of the harbour was silted up. Alterations made in the 1920's increased the silting problem. The soundings and Jet Probings were done after the Royal Commission of 1923, when the damaged stonework on the seaward side of the Warrnambool Breakwater, caused by the action of the sea, was the subject of enquiry. A conference between the Public Works, Water Commission and the Harbour Trust concluded that it would less costly to make repairs to prevent further damage rather than replaced the damage portion of the wall. A contract was raised in late 1924 to deposit rubble on the damaged side of the breakwater to minimise the Southern Ocean’s destructive action and work had started by August 1925. By the 1940's the harbour was no longer used. More alterations were made in the 1950's and 1960's. document, depth, warrnambool harbour, 1929, soundings, jet probe, jet probing, seabed, map of seabed, underwater engineering, warrnambool jetty, warrnambool breakwater, breakwater upgrade, leading lights, chart the harbour, flagstaff hill, warrnambool, flagstaff hill maritime museum & village, maritime museum, maritime village, shipwreck coast, lady bay, port of warrnambool, breakwater, jetty, pier, vhr h2024, royal commission, 1923, public works, water commission, harbour trust, victorian harbours

Reports on a Science Congress in Adelaide and a speech by Robert Risson about future transport possible systems - all types such as conveyor belts, air cushion vehicles, magnetic cushions, pneumatic tubes, moving footpaths, jet-propelled vehicles, gas turbine and diesel electric buses. These are known as "gadgetbahns" mooted proposals that seldom come to commercial fruition. His main emphasis was on the future all-electric tram fleet that was proposed for Melbourne. Also notes underground systems such as San Francisco.
