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

This program belonged to Dr James Kerr. Conceived by Engineer-in-Chief C.Y. O’Connor and completed in 1903, the Coolgardie Goldfields Water Supply Scheme comprised a reservoir on the Helena River, eight steam-driven pumping stations and 566 kilometres of steel pipeline supplying 23,000 kilolitres of water daily to the arid goldfields of Western Australia. The project was officially opened by Sir John and Lady Forrest in January 1903. "Great pomp and ceremony heralded the arrival of water and the opening of the Scheme. Clean, fresh water could now be easily obtained in some of Australia's harshest country. However, this victory came at a great cost. The stress of the bold project was too much for O’Connor, who, after enduring endless criticism, took his life on 10 March 1902, before the Scheme was completed." - Western Australian Museum : The Coolgardie Goldfields Water Supply Scheme was an ambitious engineering feat because at the time water had never been lifted so high nor pumped so far (about 560 km). The Scheme, which pumps water from the better-watered coastal area, operates to this day. This item is associated with an historic event in the history of opening up arid areas of Australia to settlement. The item is associated with Dr James Kerr, the first doctor to settle in Orbost.A souvenir program from the opening of the works of the Coolgardie Water Supply. It has a maroon cover with gold print.

This navigation cart of Lady Bay and Warrnambool Harbour was originally surveyed in 1870 but this version includes the update for magnetic variation in 1893. Since the printing of the chart several annotations have been added. These include an additional stamp dated 15-8-1910, a handwritten comment across the top of the page dated August 1910, and another handwritten comment regarding the ‘Proposed Extension of Dock’ dated 19-2-1925, plus connected drawings, notes and figures. The 1925 proposal on this chart may have been a reaction to 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. The Breakwater construction had begun in 1874 and was completed in 1890. The Victorian Government had commissioned Sir John Coode, a British harbour engineer, to present a plan to complete the Warrnambool Breakwater but his original plan was too expensive. He prepared a revised plan for a shorter structure. The construction proved to be too short to protect adequately from the weather and didn't allow enough depth for larger vessels to come into port. The decreasing trade was further affected by siltation in the bay due to the breakwater, and the completion of the railway line. The situation of the harbour became 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 and by the 1940's the harbour was no longer used. More alterations were made in the 1950's and 1960's. This chart is significant for its strong connection to the maritime history of Warrnambool Harbour and Lady Bay and the Warrnambool Breakwater. The Warrnambool Breakwater is registered as a place of significance on the Victorian Heritage Database (VHR H2024). The Warrnambool Breakwater is one of the most important late 19th century maritime engineering projects in Victoria and significant in the development of Victorian coastal shipping. It is also significant for its connection with British harbour engineer, Sir John Coode. The chart is a historical record of structures existing in 1893; the Warrnambool Jetties, Warrnambool Breakwater in Lady Bay, the leading lights (lighthouses), streets, roads, bridges and many buildings. It also shows the lay of the land and seabed. Navigation Chart: Lady Bay and Warrnambool Harbour, Australia - South Coast - Victoria. Surveyed by Nav. Lieut. H.J. Stanley, R.N., 1870. Updated for Magnetic Variation, 1893. The rectangular chart is printed on heavy cream paper. Stamps are shaped rectangular, oval and round. Around the Breakwater and Jetty area are handwritten notes, dotted and joined lines, numbers and signatures, and shading of red and green.

These plans are line drawings by the State of Victoria for a Suction Hopper Dredge, which used a suction pump to bring up material from the bottom of a body of water. The plans are contained in a box from the Public Works Department, Ports and Harbours Division in Melbourne, which in the year 1910 was responsible for the dredging operations of coastal ports and harbours, and inland waterways. The stamped signature is that of Arthur Edward Cutler, Chief Engineer, Public Works Department of New South Wales. The steel steamer Matthew Flinders was constructed by Morts Dock & Engineering Co Ltd in Sydney, New South Wales. Identified as Ship No. 40 by the ship builders, this dredge, had twin screw engines that were made in Sydney. Its gross tonnage was 1180. It was launched on July 15th, 1916, and registered by the owner, Department of Public Works in Victoria, at the Port of Melbourne in 1917. Unlike bucket dredges, the Matthew Flinders did not use permanent moorings but instead had bow and stern anchors. It travelled forward on the bow anchor, taking up a strip of even-depth wilt from the bed below. A local newspaper noted that the Matthew Flinders has many advantages that were especially useful for its work at Warrnambool. Warrnambool Harbour had been experiencing silting and sanding for many years. The problem continued even after the construction of the Breakwater in 1890, which was overseen by New Zealand engineer Arthur Dudley Dobson. Melbourne’s Department of Ports and Harbours sent the new Matthew Flinders to dredge the heavy silting in the Warrnambool Harbour in May 1919. This work was previously done by the smaller dredge, the Pioneer. However, after a month of work, the Matthew Flinders was returned to Melbourne for alterations to make it suitable for work in the heavy seas it experienced at Warrnambool. Both dredges were sent up from Melbourne when required over the years to periodically attend to the silting in the Harbour, but the Matthew Flinders was preferred because of its efficiency. It was still dredging the Harbour even in July 1938. The ship’s original master was J G Rosney. In 1923 the master in charge was Captain Dunbar. In 1930 the dredges were no longer required as the Harbour was no longer suitable as port.These plans are significant for their close association with the suction hopper dredge, the Matthew Flinders I, which was call upon often to remove the silting of Warrnambool Harbour and allow shipping to continue in the Port of Warrnambool until 1930, when the Port of Warrnambool ceased to be suitable as a port. The work done by the Matthew Flinders is significant for its association with the Warrnambool Breakwater and the on-going issues with the silting of the Harbour.

This plan is of great significance to the local history of Warrnambool, in particular the Breakwater and its impact on Warrnambool's maritime and trade history. The plan shows the existing jetties at the Port of Warrnambool, plus the partially erected Breakwater and proposed works to the Breakwater by both the Borough of Warrnambool Surveyor and Sir John Coode. The plan was signed 28th February 1879 by Sir John Coode. The legend at the bottom left describes the existing works and the proposed works. The Warrnambool Breakwater Sir John Coode was a British harbour engineer. He was brought to Melbourne by the Melbourne Harbour Trust to advise on works to improve the Port of Melbourne. The Victorian Government commissioned him to present a plan to complete the Warrnambool Breakwater. His original plan was too expensive so he prepared a revised plan for a shorter structure. The work was completed in 1890. The construction proved to be too short to protect adequately from the weather and didn't allow enough depth for larger vessels to come into port.

The Warrnambool Breakwater is registered as a place of significance on the Victorian Heritage Database (VHR H2024). It is historically significant to Victoria as one of the most important maritime engineering projects in Victoria in the late 19th century. The Warrnambool Breakwater is of historical significance as one of the most important maritime engineering projects in Victoria in the late nineteenth century. It is evidence of Victoria's nineteenth century investment in regional port infrastructure and the development of Victorian coastal shipping. It is of significance for its association with the English civil engineer Sir John Coode, the most distinguished harbour engineer of the nineteenth century, who was brought to Victoria to advise on works to improve the Port of Melbourne, but was retained by the Government to advise on improvements to the harbours at Portland, Geelong, Port Fairy, and Lakes Entrance, as well as Warrnambool. His projects for Melbourne, Lakes Entrance and Warrnambool were major engineering projects of the nineteenth century. The breakwater is historically significant as a reminder of Warrnambool's early maritime history as a Western District port, and as one of Victoria's major 'outer ports'. While the Warrnambool Breakwater is a demonstration of the engineering skills of the nineteenth century, it also demonstrates the limitations of knowledge relating to sedimentology at the time and the confidence apparent in a number of nineteenth century plans which assumed that natural forces could be overcome or contained by engineering.Plan of Warrnambool Harbour, Port of Warrnambool, dated 28 Feb 1879.

The wooden crate contains a set of patterns or moulds that were once used at Briggs’ Brass Foundry for making sand moulds. The traditional method of sand casting is over 2000 years old. It is part of a crafted process used to make brass and copper alloy goods suited to marine use; bells, boat hooks, cowls, propellers, handles, lids, rowlocks, hooks, letters, bolts, rail holders, brackets, deck plates, flanges, rudder guides, portholes and covers. Briggs’ Bronze is a copper-based alloy made from local ingots of copper, tin, zinc and lead in carefully measured quantities. The finished product is non-corrosive and can last indefinitely. The crate of patterns was donated by the Briggs family in the early years of Flagstaff Hill, along with other related items such as brassware, tools and machinery. The donated items were displayed in a simulated Brass Foundry in the Village. The items were on show from the completion of the building in 1986 until 1994 when the building was repurposed. The patterns represent the trades of foundering and metalwork, both supporting maritime industries such as shipwrights and boatbuilders. Farmers, manufacturers and other local industries also needed the castings made by foundries. The Brass Foundry display was one of the early ‘working craft’ shops at Flagstaff Hill. It included a historic Cornish chimney that was set up as a working model, telling the story of heat from furnaces to smelt metal, which would then be poured into the sand moulds. This chimney is made from specially curved bricks and is about two-thirds of its full height when originally located at the Grassmere Cheese factory. HISTORY of BRIGGS BRASS FOUNDRY: - The family business was founded in 1912 by Herbert Harrison Briggs (1963-1931) with his son George Edward Briggs, trading as Briggs & Son Foundry at 70 Wellington Street, Collingwood. Younger son Cyril Falkiner McKinnon Briggs joined the foundry in 1922, and it was renamed H H Briggs & Sons Foundry. Both sons ran the firm after Herbert’s death in 1931, making products mainly for marine purposes. They became Bell Founders in 1936 and were known for their specialty of high-quality ship bells. They produced miniature varieties of these and other decorative items such as small propellers. The firm became known as Briggs Marine Foundry. The great-granddaughter of Herbert Briggs inherited the Briggs Brass Bell, similar to the one at Flagstaff Hill. Cyril became the sole family member of the firm in 1965. The Briggs Marine was an exhibitor at the 1965 Boat Show, where he advertised as “non-ferrous founders” and “Bell Specialists”. The foundry relocated to Chesterville Rd, Moorabbin. Cyril passed away in 1967. It is thought that either Cyril or his business partner Frank Lee donated the objects from the Briggs’ Foundry around the time when the business moved to Moorabbin. However, Flagstaff Hill hadn’t been thought about until 1972. The donated items were registered in the Collection in 1986 but they could have been in storage from an earlier date. In October of that same year, Briggs Marine restored Schomberg Bell, a shipwreck artefact from the collection at Flagstaff Hill. Peter Oram, who had worked for the previous owners of Briggs Marine as a fitter and turner, took over the firm in 2014, reviving some of the old casts for current use. The business is now located at Seaford in Victoria and is part of Alliance Casting & Engineering Solutions (Alliance Casting Pty Ltd). In 2016 the original Collingwood Foundry building was repurposed as a thriving business hub named The Foundry. The crate and its patterns are significant for their association with brass foundries locally and generally in coastal areas of Victoria. Marine industries such as ship and boat building rely on good quality castings for their machinery, equipment and fittings. The patterns are associated with the long-running firm, Briggs Brass Foundry, that specialised in cast goods for the marine industry, ready to supply the needs for once-off or mass-produced items. Their products would have been fitted to sail and steam vessels along coastal Victoria including Warrnambool. Briggs Marine is also associated with the Schomberg Bell in Flagstaff Hill, restoring the bell to is former state to show an example of the bell from a luxury mid-19th century vessel. The craft of sand-casting from carved wooden patterns to create metal is an example of skills from the past that are still used today. Wooden rectangular crate with removable wooden lid. Inside is a set of wooden patterns of various shapes and sizes for making sand moulds in a metal foundry. The crate is made from thick wooden planks nailed together. The extended wooden struts on the long sides form a frame to hold the wooden lid. A pair of metal handles are at each short end of the crate, fixed with strong metal bolds. Between each pair of handles is an inscription stamped into the wood. The underside of the crate has red paint splashes. There are insect holes in the wood but no sign of current infestation.
