Electro hydraulic dredge Snake Valley 1909. J Mc Bennett, was an engineer back at the main base, at Dawson's dam on the Carngham Road, Between Linton and Snake Valley. These dredges were used for getting gold. The streams of water under high pressure just washed the hills and ground away. This dredge closed down early 1910. 200 H.P. motors were used and 10 in. pumps.Black and white image of three workmen, one beside mining building the other two at dredge pump outlet. Image mounted on dark brown card. Between 1904 and 1911 the Electro Hydraulic Company sought to extract gold in an area north of Linton known as the Hard Hills. By blasting water from high-pressure hoses into the hillsides, soil containing gold was washed out for sluicing. Two gravel pumps in Dawson's Dam pumped the wash through the sluices. Despite considerable investment in expensive equipment, the Company did not have a great deal of success, and the mining operation ceased in 1911.mining, gold, mining equipment, electro hydraulic dredge, dredging, sluicing, dawson's dam, snake valley, miners

George Milford, a long term staff member of Thompsons Foundry Castlemaine, remembers discussing Alexander Sinclair with this son, Alex Sinclair Jnr. "When Alex Jnr was a boy, his father, a senior design engineer, was sent to Malaya to oversee the erection on site of a suction cutter dredge for Thompsons. This was an adaptation of the idea of a bucket-dredge, where gold is won from alluvial gravels. In the 1915-1920 era, the Thompsons Engineering Department designed a suction-cutter dredge, by which hydraulic suction with a revolving cutter at the end of a long proboscis would collect the alluvial soil and deliver it into the dredge for recovery of the precious metals. Export marketing was then ‘all the go’, and the tin dredges were ordered from Thompsons, using the new cutter design. The dredges were, of course, shipped to Malaya in pieces, ready to be assembled on site. A number of Thompsons employees were selected to travel to Malaya to assemble the dredges. There were fourteen men in the gang. These men sailed on 1st July 1925, their number including Delmenico, McKay and Charles Albert Hauser, an engine driver. C A Hauser died of malaria in Malaya shortly after arrival. Components for a further three of these dredges were in transit or on site when the first suction-cutter dredge was assembled and tested. The designers had failed to take into account the fact that, in the jungle floor in Malaya, many trees grow up, and fall down, in tropical conditions, and become submerged still waterlogged in the floor of the jungle, and in the tin-bearing gravels. The suction-cutter dredge was found to be inefficient in these circumstances, the price of tin had fallen and the Malayan client reneged on the contract. Faced with an outlay of over £4,000 on which no money would be received, the company went bankrupt on 25th August 1925. Alex Sinclair Snr was at that stage in Malaya, and received the news of the bankruptcy by telegram. Upon telegraphing his employers for funds to return home, he received the reply that there were no such funds available. Alex Sinclair Jnr told the story of how his father worked as a labourer in Malaya for two years, while his mother took in washing and ironing during the same period, until together they had assembled enough money to pay for his father’s return Anyone who talks about “the good old days” is talking nonsense!"Large blue printed paper plan outlining the conditions of contract for the making of a steel boiler.

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 photograph shows the steam dredge Pioneer working to remove silt in Lady Bay, Port of Warrnambool. The dredge belonged to the Ports and Harbours department in Melbourne. Also in the photograph are two moored vessels, and the Warrnambool Lifeboat shed and Rocket house built on the Warrnambool Breakwater. The Warrnambool Harbour had been experiencing heavy silting and sanding for many years. The problem continued even after the construction of the Breakwater in 1890. The Ports and Harbours' new, larger suction hopper dredge, the Matthew Flinders, was also employed in May 1919 to remove the heavy silting in the Harbour. Both dredges were sent up from Melbourne when required over the years to periodically attend to the silting. The Matthew Flinders was still dredging the Harbour even in the 1930s. (The ship’s original master was J G Rosney. In February 1922 Percy Taylor from Ports and Harbours joined the Matthew Flinders as a Mate. 1923 the master in charge was Captain Dunbar. In August 1926 Percy Taylor was appointed as her Master and was later transferred to the Pioneer as Master in 1933.) 1930 the dredges were no longer required as the Harbour was no longer suitable as a port. However, one source notes that the Matthew Flinders was still dredging the Harbour in 1938.This photograph is significant for its association with the Port of Warrnambool, the Warrnambool Breakwater, and the issue of the silting in Lady Bay. The photograph is significant historically as it shows a point in time when efforts were employed to keep the Port of Warrnambool functioning, allowing shipping activities to continue operating. The need for dredging in the Warrnambool Harbour was a serious and ongoing problem, as silting continued to happen after a series of measures were taken to try and resolve the issue. Eventually, the Harbour could no longer function successfully as a port.Photograph, black and white, showing two similar images and printed together.
