This knife is believed to belong to the household of Chiltern writer and historian, W.C. Busse. It displays a level of tarnish indicating it may be comprised of silver or silver plate. The blade contains the mark 'EP' which may indicate silverplate over steel. The blade also contains the maker's mark 'Wingfield', which was the trademark of T. Turner & Co but could also refer to the company Wingfield Rowbotham. Both factories are located in Sheffield, United Kingdom. The trademark is ascribed to goods produced in approximately 1907. The handle of the knife displays the initials 'WB', potentially indicating it was made to order. Wilfred Clarence Busse was born in Chiltern in 1898. He went to school at Wesley College in Melbourne, studied law at the University of Melbourne and became a barrister. Additionally, after spending time on a Victorian station in his early twenties, he wrote two historical novels about bush life. His first novel was 'The Blue Beyond: a Romance of the Early Days in South Eastern Australia', written in 1928 and published in 1930. Busse's second novel was titled 'The Golden Plague: A Romance of the Early Fifties'. The judges of the Henry Lawson Society's T.E. Rofe competition to advance Australian literature unanimously awarded it the Gold Medal in 1931 for the best historical novel of 1930. Newspaper articles about the award mention the writer's meticulous documentary and oral history research regarding life on the Gold Fields in the 1850s. It became a best-seller. Busse also wrote a series of articles about local history for "The Federal Standard" newspaper in Chiltern. He was a member of the Chiltern Athenaeum. He died in 1960.This knife is significant for the detail it conveys of ordinary domestic life in the household of a significant Victorian writer with special reference to Chiltern and the surrounding region.

This scarf was commissioned by Ben Mountford who was part of the Collaborative Research Centre in Australian History (CRCAH) based at the Federation University SMB Campus (former Ballarat School of Mines). Ben now works at Australian Catholic University, but before that he held a lectureship at Federation University Australia as well as research fellowships at La Trobe University and the Huntington Library, and a lectureship at the University of Buckingham. From 2008-15 he was at Oxford University. Up to eight scarves were made in the Ballarat School of Mines colours for various staff members for the 2016 Australian History Association Conference which was held in Ballarat. This scarf was a gift to John McDonnell and was donated when clearing his office in 2018 after finishing in the position of Dean of Education at Federation University.This acrylic knitted bottle green scarf with gold stripes has green and gold fringing on both ends and the crest of the Ballarat School of Mines embroidered on one end.ballarat school of mines, collaborative research centre in australian history, crcah, scarf, ballarat school of mines crest, ben mountford

Taken between circa 1920 - 1930 this photograph depicts a Hydraulic water jet in the foreground and a man dressed in dark trousers, a white long sleeved shirt and broad-brimmed workers hat digging around in the Three Mile Mine at Barramutha. The mine was an important gold resource and was typically mined using a method known as hydraulic sluicing whereby high powered water jets are used to dislodge rock or move sediment. The remaining water sediment slurry is directed through sluice boxes to remove the gold. The Beechworth mining district was one of six mining districts established by the governor-in-council on 4th of January 1858 under the provisions of An Act for Amending the Laws Relating to the Goldfields (21 Vic no. 32).This photograph shows cultural and research value into the historical methods of hydraulic sluicing in the Beechworth mining disctrict. It also shows the evolution of the mining methods and has potential for understanding future engineering endeavors in the context of victorian mine goldfields.Black and White rectangular photograph printed on matte photographic paper.
