The Wilks Creek Bridge is a former timber and bluestone road bridge on the Yarra Track, and is located just off the Black Spur route, between Narbethong and Marysville, Victoria, Australia. It was built in 1870 to the design of colonial Public Works Department engineer Clement Wilks as part of the construction of a new road to the Woods Point and Jordan Goldfields. Like many bridges of the period, it had a timber superstructure employing squared beams supported by struts and straining pieces, on cut bluestone abutments. The bridge was remodelled around 1900 by engineer John Monash of the famous bridge-engineering firm of Monash and Anderson. It was last used for heavy vehicular traffic in 1980 following the realignment of Marysville Road, and was left to decay until its demolishment in 2008. All timber traces of the bridge were destroyed in the 2009 Black Saturday fires. The handcrafted bluestone masonry wingwalls and abutments, especially shaped to receive timber struts, rate among the earliest of its kind surviving intact in Victoria.wilks creek bridge, yarra track, narbethong, marysville, victoria, clement wilks, wood's point goldfields, jordan goldfields, john monash, monash and anderson, 2009 black saturday bushfires

The chimney extension on what was the former Carlton and United Breweries boiler house at Ballarat installed in 1972 and it is constructed of a special formulation of fibreglass reinforced plastics designed to operate at elevated temperature (ie boiler flue gas). It is thought to be one of 26 or 28 fibreglass boiler chimneys designed and installed in Victoria in the 1970s, and is thought to be one of the last to be removed. In its day the fibreglass chimney extension was at the cutting edge of fibreglass technology and is therefore well worth retaining. Removal of the chimney extension to the brick chimney outside the brewery building was deemed necessary to prolong the life of the chimney, and also because the fibreglass extension had reached end of life and posing a possible threat. According an Engineering assessment, fibreglass structures have a life expectancy of between 20 years (when fatigue loaded) and up to 100 years (static loaded). We don’t know when it was added to the chimney but believe it was most likely in the early 1970s. Given that it is subject to wind load and often observed to be moving in the wind it is likely that it will be at the end of its life. The chimney will be made good and we have the necessary planning approvals in place to undertake the works. The chimney extension was removed on 13 November 2015 in accordance with a planning permit obtained by the University. The extension is believed to have been added in the 1970s and was predominantly made from fibre glass. The structure was removed for safety reasons and to preserve the integrity of the historic brick chimney which supported it.

Sport and available playing areas were important and every effort was made to provide this for the students when they moved into the new building in 1921. The terraces leading down from the gaol wall were terraced and clearing areas of rubble to provide playing areas for football and cricket was done by the students. In November 1922, a tennis court was opened in the Battery Paddock. It was designed by Syd Chambers and constructed by Les Waller, former students of the Ballarat School of Mines. A new tennis court was built and opened in 1934, in the same area. This photograph is of the 1938 Tennis Team - Ballarat Junior Technical School. The boys standing are L to R: D. Eltringham and J.

Before the introduction of electricity, lighthouses had a clockwork mechanism that caused the lens to rotate with a light source inside that was either powered by Kerosene or Colza oil. The mechanism consisted of a large weight attached by a cable through the centre of the lighthouse to the top where the cable wrapped around a barrel, drum or wheels that controlled the speed of the lights rotation by a clockwork mechanism. The keeper would crank the clockwork mechanism, which would lift the weight ready for the next cycle similar to an old grandfather clock mechanism. Once the weight lifted to its apex at the bottom of the first landing, the keeper would let it fall, which would pull on the cable, which would, in turn, operate a series of gears activating the rotation of the Fresnel optical lens, which would then rotate to create the lighthouse’s unique light speed of rotation characteristic. Creating a specific characteristic required a way to regulate the speed of the rotation, and was important as sailors could identify a particular light by its speed and time between flashes. The weight had to fall at a certain rate to create the proper rotation speed of the lens and a regulator within the mechanism accomplished this. History: From 1851, Chance Brothers became a major lighthouse engineering company, producing optical components, machinery, and other equipment for lighthouses around the world. James Timmins Chance pioneered placing lighthouse lamps inside a cage surrounded by Fresnel lenses to increase the available light output these cages, are known as optics and they revolutionised lighthouse design. Another important innovation from Chance Brothers was the introduction of rotating optics, allowing adjacent lighthouses to be distinguished from each other by the number of times per revolution the light flashes. The noted English physicist and engineer, John Hopkins invented this system while employed at Chance Brothers. Chance Brothers and Company was a glass works and originally based in Spon Lane, Smethwick, West Midlands England. The company became a leading glass manufacturer and a pioneer of British glass making technology. The Chance family originated in Bromsgrove as farmers and craftsmen before setting up a business in Smethwick near Birmingham in 1824. They took advantage of the skilled workers, canals and many other industrial advances taking place in the West Midlands at the time. Robert Lucas Chance (1782–1865), known as 'Lucas', bought the British Crown Glass Company's works in Spon Lane in 1824. The company specialised in making crown window glass, the company ran into difficulty and its survival was guaranteed in 1832 by investment from Chance's brother, William (1788 – 1856). William owned an iron factoring business in Great Charles Street, Birmingham. After a previous partnership that Lucas had dissolved in 1836, Lucas and William Chance became partners in the business which was renamed, Chance Brothers and Company. Chance Brothers invented many innovative processes and became known as the greatest glass manufacturer in Britain. In 1848 under the supervision of Georges Bontemps, a French glass maker from Choosy-le-Roi, a new plant was set up to manufacture crown and flint glass for lighthouse optics, telescopes and cameras. Bontemps agreed to share his processes that up to then had been secret with the Chance Brothers and stayed in England to collaborate with them for six years. In 1900 a baronetcy was created for James Timmins Chance (1814–1902), a grandson of William Chance, who had started the family business in 1771 with his brother Robert. Roberts grandson, James became head of Chance Brothers until his retirement in 1889 when the company became a public company and its name changed to Chance Brothers & Co. Ltd. Additional information: Lighthouses are equipped with unique light characteristic or flashing pattern that sailors can use to identify specific lighthouses during the night. Lighthouses can achieve distinctive light characteristics in a few different ways. A lighthouse can flash, which is when brief periods of light interrupt longer moments of darkness. The light can occult, which is when brief periods of darkness interrupt longer moments of light. The light can be fixed, which is when the light never goes dark. A lighthouse can use a combination of flashing, oscillating, or being fixed in a variety of combinations and intervals to create individual light characteristics. It is a common misconception that a lighthouse's light source changes the intensity to create a light characteristic. The light source remains constant and the rotating Fresnel lens creates the various changes in appearance. Some Fresnel lenses have "bulls-eye" panels create beams of light that, when rotated between the light and the observer, make the light appear to flash. Conversely, some lenses have metal panels that, when rotated between the light and the observer, make the light appear to go dark. This Dioptric clockwork apparatus used to turn a lighthouse optical lens is very significant as it is integral to a lighthouses operation, we can also look at the social aspect of lighthouses as being traditionally rich with symbolism and conceptual meanings. Lighthouses illustrate social concepts such as danger, risk, adversity, challenge and vigilance but they also offers guidance, salvation and safety. The glowing lamp reminds sailors that security and home are well within reach, they also symbolize the way forward and help in navigating our way through rough waters not just on the oceans of the world but in our personal lives be it financial, personal, business or spiritual in nature. Nothing else speaks of safety and security in the face of adversity and challenge quite the way a lighthouse does.
