This book contains letters and mathematical computations on hydraulic engineering. The material has been compiled by Arnold Lilley (Lilly), an Oxford mathematician working in Victoria in the 1890s. It is said that he taught or coached 95% of the municipal surveyors in Victoria in the 1890s. The book came from the office of one of Lilley’s pupils, John William Crawley Junior, an engineer, surveyor and architect with a private practice in Warrnambool and also the engineer for the Shire of Warrnambool from 1895 to 1935. It is presumed that he had the letters bound in book form. The book passed to his son, Rolf Crawley, the engineer for the Shire of Warrnambool from 1935 to 1968. It later came into the possession of Michael Hand who took over the private surveying business of Rolf Crawley in Warrnambool. The Warrnambool and District Historical Society acquired the book, along with other Crawley ledgers, from the estate of Michael Hand.This book is of interest as a memento of the 1890s teachings of the mathematician, Arnold Lilley and also of his pupil, John William Crawley, the engineer for the Shire of Warrnambool for 40 years.This is a blue hard-cover book containing handwritten letters and computations. There are some loose pages and some pages have postal stamps on them. The book spine is slightly scuffed. ‘Letters on Hydraulic Engineering by Arnold Lilly Esq Mathematical Coach. J. Wm.

In 1875, the Rocky Mountain Extended Gold Sluicing Company Ltd was created, utilising the previous Rocky Mountain claim for the area near Lake Sambell. The company employed A.L Martin to survey an area for a tunnel underneath Beechworth and Johnson Stephens to dig it. The tunnel was built at a rate of 40 feet a month and eventually measured 800 metres. The tunnel was a true accomplishment both in the present and during the 19th century. It was considered to be a marvelous engineering feat. Beechworth is renowned for its hydraulic sluice method of mining. This involved soil being exposed to torrents of water from high-pressure hoses. From 1876 until its closure in 1921, the mine produced an astounding 47,926 ozs of gold. Companies like this were the source of income for many Chinese gold-diggers who sought to make their fortune on the goldfields of Beechworth. During the height of the rush, the town had around 7,000 Chinese inhabitants living on the outskirts of town as they were not permitted to live within Beechworth itself.The search for gold is ingrained into the history of Victoria and therefore, images like this one which portrays an open-cut sluicing site can reveal important information for society and technology for the date when the photograph was taken. This image is of important historical significance for its ability to convey information about sluicing and the methods used to find gold in 1910. It also shows a location where sluicing was undertaken which provides insight into the impact of sluicing on the environment at a time when it was done. This image of the Rocky Mountain mine is historically significant as the mining complex is now non-existent, with the only remains being the tunnel built in 1880 by the company, which was considered one of the greatest engineering feats of the time. The image also provides a first-hand look into the social and cultural networks at play during the 19th century with racial segregation of the Chinese at the 'Chinese Camp', as well as an insight into Beechworth's origins during the Gold Rush.A sepia rectangular photograph printed on matte photographic paper as a postcardReverse: Historic Beechworth / 7792.1 / ROCKY MOUNTAIN MINE / Viewed from the “Chinese Camp”, shown partly in the foreground, we see the central plant of the famous Rocky Mountain Mining Company.

Depicted in the photograph are ten miners standing at a cliff face using a high pressure hose, in Beechworth, Victoria. The miners are located in the Three Mile Creek division, in the Beechworth Mining District established January 4th 1858 under An Act for Amending the Laws Relating to the Goldfields by the Governor-in-Council. The Ovens Gold Rush began at Beechworth in February 1852 and was followed by Yackandandah and the 'Indigo Goldfield'. The strategies applied to mining in Beechworth were distinct in comparison to other goldfields in Victoria such as Bendigo and Ballarat. The miners in Beechworth utlised 'hydraulic sluicing' to remove washdirt, the long water races and deep tailraces constructed through solid rock with an estimated 900 miles of water races cut through the Beechworth fields by 1880, demonstrating great engineering feats. The photograph taken is significant as it is a visual representation of the mining strategy, 'hydraulic sluicing' that was particularly unique to the Beechworth mines, particularly in Victoria and an engineering feat.Black and white rectangular photograph printed on matte photographic paper, unmounted print.beechworth mining district, mining, three mile creek division, three mile creek

This image shows the approach to Beechworth from the south-west via the Newtown Bridge. Numerous early buildings line the road as it bifurcates to become Ford and High Streets on the ridge above Spring Creek and Newtown Falls. The sloping, rocky terrain and water course along the gorge show evidence of the intense mining activity that occurred at the site. The Ovens Gold Rush at Beechworth started when gold was found at Spring Creek in February 1852, prompting an influx of miners from around the world. The population grew over 20,000 by 1857. While the earliest mining at Beechworth was similar to that in other Victorian goldfields like Ballarat and Bendigo, Beechworth is notable for its use of hydraulic sluicing as a major method of removing wash-dirt. Hydraulic sluicing employs high pressure jets of water to blast away large areas of earth and wash it down to be run through a sluice box. Gold gets caught in the sluice and the remaining slurry is washed away. This method of mining is extremely effective but causes significant environmental impacts and damage to waterways. Large water quantities were required for large-scale sluicing, and the long water races and deep tailraces that were constructed in the Beechworth area in the nineteenth century are nonetheless considered feats of engineering. The site in the photograph is associated with the Rocky Mountain Mining Company who constructed an eight hundred meter tunnel under the township between 1876-1880 to reduce water levels at Spring Creek, which had been subject to diversions since the earliest days of alluvial mining. Over four million ounces of gold (115 tones) were found at Beechworth between 1852 and 1868, and the wealth from the gold rushes built Beechworth and the nationally significant buildings that remain standing today.This image shows the early development of the Beechworth township above Spring Creek, where gold was discovered in 1852. Evidence of hydraulic sluicing, a uniquely predominant method at Beechworth, and water-works engineering are present in the landscape. By the 1870s, alluvial gold deposits were depleted and increasingly complex engineering was required so deeper shafts could reach bedrock. This image is significant for understanding changes to the landscape and the evolution of mining methods and engineering practices related to the extensive construction, manipulation and management of water networks. The shift from smaller scale alluvial mining to larger company dominance in the mining industry has implications for understanding wider social, economic, political and industrial changes in the region of Beechworth and within the context of the Victorian Gold Rush more broadly.

This image taken between 1920-1930 depicts open-cut hydraulic sluicing at the Three Mile Mine, located about five kilometres south of Beechworth. Alluvial, or surface, mining began on this site in the 1850s, but was soon replaced by hydraulic sluicing methods. By the start of 1880 it is estimated that nine hundred miles of water races had been cut though soil and rock in the Beechworth district. Hydraulic sluicing employs high pressure jets of water to blast away large areas of earth and wash it down to be run through a sluice box. Gold gets caught in the sluice and the remaining slurry is washed away. Large water quantities were required for hydraulic sluicing, and the long water races and deep tailraces that were constructed were considered great engineering feats. This method of mining is extremely effective, but causes significant environmental damage and impacts to waterways and agricultural operations. Miners at Beechworth built extensive networks of races and dams to secure reliable supplies of water on a scale far greater than elsewhere in Victoria. By the 1880s Beechworth's water barons continued to hold more than half of all the water right licences on issue and undertook sluicing operations on a massive scale. The manipulation of surface and ground water via race networks was well planned and recorded in detail by local mining surveyors. The maps that were created, combined with modern geo-spatial technologies, provide a vital key in understanding the great lengths to which miners went to capture and control critical water resources. Today, Three Mile mine is called Baarmutha. The Three Mile Mine was unproductive until 1865 when John Pund and three other miners secured a fifteen year license and constructed a water race from Upper Nine Mile Creek to Three Mile Creek. In the early twentieth century Pund & Co. averaged over one thousand ounces of gold per year from the mine. After Pund's death in 1915, GSG Amalgamated Co operated the site, continuing sluicing until 1950. This image of hydraulic sluicing methods shows the extent of water-works engineering in the landscape. This photograph has historic and research potential for understanding changes to the landscape, the evolution of mining methods, and the extensive construction, manipulation and management of water networks in the Beechworth district.

The photograph depicts a mine cut with a tractor. Water is being used to sluice the front of the tractor, possibly to separate any gold that may have been picked up from the earth. A few people watch the demonstration. Water was a significant part of gold mining in the Beechworth area and miners used a method known as 'hydraulic sluicing'. Due to the amount of water required, many water races were constructed throughout the Beechworth Mining District. These were cut through solid rock and are an example of engineering achievement. Water usage in the area put Beechworth at the heart of water policy, with many firsts for Victorian colonial goldfield water management being established in the Beechworth Mining District. This photograph is significant as it depicts the use of water in gold mining in Beechworth. Beechworth was notable for it's use of water in mining.Black and white square photograph (portrait orientation) printed on matte photographic paper.Reverse: SW-50-2 / 1997 31136 / unreadable pencil markingssluicing, gold mining, mining, hydraulic sluice, hydraulic sluicing, beechworth mining district

John Hastie Engineer and millwright John Hastie opened small manufacturing works in Greenock in 1845 and 1853 patented the first self-holding steering gear. The firm became known as John, Hastie and Co. Ltd. in 1898 after taking on limited liability status and their main works were at Kilblain Street, Greenock, where they specialised in ships' steering gear. The company also occupied works at Rue End Street, Greenock. Plans of this unit depict a stockyard to the east, with areas for welding; fitting and assembly; flame, cutting and fabrication; and a machine bay. The company was dissolved in 1991. Brown Brothers Brown Bros Rosebank Ironworks made the steering gears for many large ship's, including The Titanic. Andrew Betts Brown the founder was born in 1741 and closely associated with many improvements in marine engineering. He was educated in his native city and served his apprenticeship as an engineer in the locomotive works of the North British Railway Company at St. Margaret's. During his apprenticeship, he attended the evening classes at Watt College. subsequently going to Manchester to study chemistry. He went to London around 1863 and took over an old brewery, which he converted into an engineering works. During his time there he invented an overhead travelling crane, which was used on the construction of Blackfriars Bridge London. He went on to develop plant which used steam and hydraulic power for discharging ships as a result the company was contracted to install this equipment in Hamburg Docks. ​ By around 1870 he continued to construct machinery in London but realised that conditions were more favourable in Edinburgh. He acquired land at Rosebank adjoining the North British Railway Company's line to Granton, and the necessary infrastructure was completed allowing him to finish the Hamburg contract. The works at Rosebank were eventually extended and added to until they became one of the largest engineering works in the East of Scotland. ​ Mr Brown was a member of numerous engineering institutions, the best known at the time being the Institution of Naval Architects. He was also a Fellow of the Royal Society of Edinburgh, a member of the Institute of Mechanical Engineers and of the Institution of Marine Engineers he died in 1906 at the age of 67.An item made by two marine innovators of marine auxiliary machinery, equipment and itemsShip's wheel, brass, attached to brass pillar.

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.
