William Rae (1823-1887) was born into a farming family in Scotland and came to Australia in i852. After coming to the Bendigo area, he established a puddling machine in American Gully. He then bought a claim on the Victoria reef and was quite successful. Subsequently he bought a steam engine and three batteries to begin crushing quartz. This was such a boon that he moved to a more convenient location in Happy Valley, where he set up a crushing battery with 35 heads.Sketch of a crushing works. Printed underneath is: Wm.

Gold was first discovered in 1852 on what was then named Korong or Mt Korong goldfields. It was soon found that the area was not suitable for alluvial mining because of a lack of water but quartz mining was more successful. The township of Wedderburn was surveyed 1856/57. The first public crushing works was established in 1859.Hardcover book with printed dust jacket and plastic cover. 92 pages with black and white illustrations, fold out map and index.

Fortuna Villa was initially commenced as a modest single storey home in 1861 next to the 180 Mine by Theodore Ballerstedt, who sold the mine and house to George Lansell in 1869. Lansell already owned the adjacent Fortuna Mine, and through deeper mining techniques greatly expanded the mine's operation, his personal wealth, and the house and grounds. Lansell was soon known as the 'Quartz King', Australia's first gold mining millionaire and credited as the driving force behind much of Bendigo's prosperity. He continuously added to and expanded the villa, decorating it extravagantly with the finest of artworks and materials, into a sprawling mansion with extensive landscaped grounds, to create a house and grounds of a size and grandeur with few rivals in Australia. After his death in 1907, his second wife Edith carried on with improvements, creating a house and grounds developed over 50 years. The attached mine also contributes to its significance, being one of the richest mines in Bendigo, and at one stage probably the deepest gold mine in the world at 3176 feet. The 1875 crushing works are attached directly to the mansion, and the mine's tailings and settling ponds (turned into ornamental lakes) represent a direct link between George Lansell's wealth and its source. Fortuna was compulsorily acquired by the Commonwealth in 1942 as the Cartographic Headquarters of the Australian Survey Corps during World War II, and many ancillary structures were added while preserving the main house and ornamental grounds.

This is a set of 17 photographs taken during the first year of Army occupation at Fortuna, Bendigo in 1942. The photos provide an insight into the preparatory work performed on the Fortuna Villa and surrounding buildings, by the Working Party 5th Army Troop and Ordnance Training Depot, before its occupation by personnel from LHQ Cartographic Company, Royal Australian Survey Corps. The annotation on the back of Photos .9P and .10P is misspelt. The correct spelling is ‘Nell Gwynne’. The poppet head of the Central Nell Gwynne mine is still an iconic landmark in Bendigo, lying just down the road from the poppet head lookout at Victoria Hill. The Central Nell Gwynne was the premier mine of Bendigo's 1930s mining revival and is of high historical value, due to the extensive and relatively intact features which remain at the site. The annotation on the back of Photo .17P is incorrect. The location of HQ 5th Army Troop was ‘Reynard St, Coburg.’ By late 1941 as Japan extended its control throughout Indo-China, resolving the accommodation problem of AHQ Cartographic Company located in Melbourne became more urgent. The steady Japanese advance made the bombing of Melbourne no longer a remote possibility, and in accordance with a general policy of dispersion, the Deputy Chief of the General Staff, Major General Sidney Rowell instructed Major William Sarll, in the interests of security of plant and to provide against possible damage of air attack, to investigate suitable safer inland accommodation for AHQ Cartographic Company. Major Sarll inspected many properties before finding one that would meet the requirements of the Cartographic Company. In late 1941, he came to inspect Fortuna, a rambling old mansion with about fifteen acres of ground in central Bendigo. Initially there was no intention to occupy the site beyond the end of the war, although Major Sarll's report to the Director of Survey noted many advantages in moving the Company to Bendigo. Major General Rowell quickly approved the selection of Fortuna before other authorities, which were investigating the evacuation of school children, could get in ahead of the Cartographic Company. On 23 March 1942, the Commonwealth of Australia, under the provisions of the National Security Act of 1939, took possession of the house, the old battery buildings and the fifteen acres of grounds. Under Warrant Officer J. Trist’s direction, over fifty Parks and Works tradesmen completed building works necessary to accommodate the Survey Corps’ military, map making and printing requirements. The building program was still under way when the first officer, Lieutenant Ralph Westgarth, arrived in May 1942 with the advance party which received and positioned all equipment as it came up from Melbourne in semi-trailers. Once the equipment was installed the rest of the Cartographic Company completed its shift to Bendigo by 11th June 1942. The first year of the Survey Corps’ occupation of Fortuna is covered in more detail with additional historic photographs, in pages 17-22 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4.This is a set of 17 photographs taken during the first year of Army Occupation at Fortuna, Bendigo in 1942.

The mortar is a bowl, typically made of hard wood, ceramic or stone. The pestle is a heavy club-shaped object, the end of which is used for crushing and grinding. The substance to be ground is placed in the mortar and ground, crushed or mixed with the pestle. The mortar and pestle is usually utilised when cooking and when crushing ingredients for a certain drug in pharmacies. For pharmaceutical use, the mortar and the head of the pestle are usually made of porcelain, while the handle of the pestle is made of wood. This is known as a Wedgwood mortar and pestle and originated in 1779. Glass mortars and pestles are fragile, but stain-resistant and suitable for use with liquids. However, they do not grind as finely as the ceramic type The mortar is a thick clear glass bowl and the pestle is a solid clear glass club-shaped tool for crushing tablets to a finer powder or mixing liquids by a pharmacist.pharmacy, mortar & pestle, medications, medicines, glass manufacturing, glass works, early settlers, moorabbin, bentleigh, cheltenham

"The United Pyrites Company's Works are situated about three quarters of a mile from Spargo Brothers, and are on the northern side of the Marong road, in Pinch-gut Gully. Two processes are followed at these works, viz., the amalgamating process and the treatment by means of chlorine gas. The latter is called the Newbery-Vautin system, and the mode pursued is that laid down by Mr. Cosmo Newbery and Mr Vautin, whose names have been given to the process. Mr. Edwards manages these works. Three reverbatory furnaces are used to roast the pyrites, which is weighed in the truck before being put into the furnaces. At this weighbridge a sample of each lot is kept, and if the yield is not equal to expectation, the works are carefully gone over to see where the fault occurs. Care is taken at the furnace to regulate the heat, otherwise the pyrites might slag instead of roasting evenly right through. An immense revolving furnace (made of boiler iron) was used at these works. It was found to be suitable for treating blanket sand, but was not a success for roasting coarse pyrites. The process of amalgamating by means of Chilian mills is the same in these works as at the Western Works, but the United Works are on a larger scale, and eleven mills are utilised. It is the chlorine gas process which is most interesting here. The gas is made from sulphuric acid, black oxide of manganese, and common salt, and the gas is introduced into huge vats, where it works its way through a filter of pieces of quartz and then through the bed of roasted pyrites lying above. The action of the gas transforms the gold into chloride of gold. This is easily dissolved in water, and in that form is drawn off into huge delf jars, where the use of sulphate of iron precipitates the gold to the bottom. A small battery—eight head of stamps in two boxes—is in use here to crush small consignments of stone sent for trial. Test crushings come from all the Australasian colonies, and even from India. The jars used are manufactured at Epsom, and some of the salt used is also of home manufacture, from the Salt Lakes on the Northern plains. Mr. Edwards took us over a new building in course of erection, and in which the chlorine gas is to be generated in the midst of the pyrites— a still further advancement in the new process. There is some very good machinery in this new building, and the tailings from the ordinary pyrites works will also be treated by this chlorine gas system, which has been found to work well at Mount Morgan, in Queensland. The purest of gold is obtained by this process, the gold passing in solution into a charcoal filter, from which it emerges in the shape of metallic gold. We saw some nice cakes of retorted gold at the works. One of 26oz. was from some New Zealand pyrites (2½ tons), and assayed over 23 carats. There were also cakes of Avoca gold, of silver, and of the tremulous amalgam."
