Gold was found at Club Terrace in 1896. One of the best finds at Club Terrace was the 'Ace of Clubs' mine which was later sold to the Mallina Gold Mining Company. Syd Cadwallader was appointed manager of the company. The gold was smelted and brought to Orbost on horseback. The only protection against thieves was a revolver and riding crop, which the manager always carried. The 'Ace of Clubs' was eventually closed as the company was unable to cope with the rising water problem.

A Large Rare mid 19th Century Balance Scale (also called a Beam Scale) Made in England by W&T Avery a British manufacturer of weighing machines. The company was founded in the early 18th century and took the name W & T Avery in 1818. The undocumented origin of the company goes back to 1730 when James Ford established the business in the town of Digbeth. On Joseph Balden the then company’s owner’s death in 1813 William and Thomas Avery took over his scale making business and in 1818 renamed it W & T Avery. The business rapidly expanded and in 1885 they owned three factories: the Atlas Works in West Bromwich, the Mill Lane Works in Birmingham and the Moat Lane Works in Digbeth. In 1891 the business became a limited company with a board of directors and in 1894 the shares were quoted on the London Stock Exchange. In 1895 the company bought the legendary Soho Foundry in Smethwick, a former steam engine factory owned by James Watt & Co. In 1897 the move was complete and the steam engine business was gradually converted to pure manufacture of weighing machines. The turn of the century was marked by managing director William Hipkins who was determined to broadening the renown of the Avery brand and transforming the business into a specialist manufacture of weighing machines. By 1914 the company occupied an area of 32,000m² and had some 3000 employees. In the inter-war period the growth continued with the addition of specialized shops for cast parts, enamel paints and weighbridge assembly and the product range diversified into counting machines, testing machines, automatic packing machines and petrol pumps. During the second world war the company also produced various types of heavy guns. At that time the site underwent severe damage from parachute mines and incendiary bombs.Then from 1931 to 1973 the company occupied the 18th-century Middlesex Sessions House in Clerkenwell as its headquarters. Changes in weighing machine technology after World War II led to the closure of the foundry, the introduction of electronic weighing with the simultaneous gradual disappearance of purely mechanical devices. The continued expansion was partly achieved through a series of acquisitions of other companies. After almost a century of national and international expansion the company was taken over by GEC in 1979. Keith Hodgkinson, managing director at the time, completed the turn-around from mechanical to electronic weighing with a complete overhaul of the product range of retail scales and industrial platform scales. In 1993 GEC took over the Dutch-based company Berkel and the Avery-Berkel name was introduced. In 2000 the business was in turn acquired by the US-American company Weigh-Tronix, who already owned Salter, and is today operating as Avery Weigh-Tronix. Item made and used possibly around the 1850s by Victorian colonial government to check weights of goods being sold by early shop keepers on the gold fields item is very rare.James McEwan & Co were the retailers of W & T Avery scales in Victoria from 1852. A very rare item used probably to check weights used by merchants during colonial times by government inspectors in Victoria. A similar example exist in a NSW museum, the item is believed to have been made before W & T Avery expansion to the Soho foundry in Birmingham in 1885 and after 1818.Beam balance scale suspended from a wooden tripod, with metal trays suspended by three chain lengths. embossed on the balance beam W T Avery, Birmingham,flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, scale, avery

This painting is one of a pair of large paintings by W. Langley-Taylor in our collection. Currently, no further information has been found about the artist but research is ongoing. The subjects of these paintings are seascapes of notable areas of the coast on each side of Port Phillip Bay, south of Melbourne, Victoria. The subject of this painting is Cape Schanck, Victoria, which is on the east side of Port Phillip Bay. It includes the Cape Schanck Lighthouse and its Flagstaff. The Cape Schanck Lighthouse was built in 1859 and is the second of Victoria’s coastal lights. It is 21 metres tall and made from limestone. Unusually, its stairway is made from stone rather than wrought iron. Gilded tours are available to explain its use and significance to visitors. The lighthouse keepers at Cape Schanck kept records of the ships that sailed past them along Bass Strait; ship’s names, direction, time and date and so on. The details would also be passed on to shipping agencies, Harbour Masters and newspapers, which published Arrivals and Departures into and out of shipping ports such as Port Phillip Bay and the Port of Melbourne. INSCRIPTIONS “Mrs M Irby” (and on the Eagle Rock, Warrnambool, painting “980/Regency”) The inscription “Mrs M Irby” is on the back of both paintings but the significance of the inscription has not yet been discovered. Perhaps she was connected with the ship or shipping company “Irby”. A ship named “Irby”, built in Merseyside, Liverpool in 1881 by R & J Evans, Birkenhead. It was a four-masted iron ship built for the White Star Line. Henry Wilson Hewitt bought her in 1882, then later she was owned by Chadwick & Pritchard. In 1888 she was registered under the Irby Ship Co. Ltd. (trading as J. Joyce) in Liverpool. In 1912 Galgate Co. Ltd owned her. She traded between London, England and Australia, and is recorded as being in Melbourne and Hobart. In 1919 the Irby was destroyed by a mine when on her way to England. Or perhaps her name and the inscription in pencil “980/Regency” on the Eagle Rock Warrnambool, painting could be a delivery address for the paintings, perhaps an apartment in a hotel. NOTE: The artist’s spelling of the title “Cape Schank, Vic.” is incorrect. The location in this painting is named Cape Schanck. This painting is significant geographically for its representation of the coastal scenery of Victoria, Australia. It is also significant as one of a pair of paintings of seascape, one at sites each side of Port Phillip Bay. The painting is significant historically as an example of late 19th and early 20th methods and materials used to construct a painting’s frame. Painting oil on board in a dark wooden frame, portrait orientation. Seascape of coast with cliffs, lighthouse and flagstaff, flying birds, high waves breaking onto rocks, blue sky with clouds. The title is painted on lower left corner and the Victorian artist, W. Langley-Taylor, has signed his name on lower right. The inscription on back is handwritten script in red crayon or thick red pencil. The board is held in place inside the timber frame with small, dark metal tacks around all sides. Metal eyes join the wire to the frame. Small round, dark metal nail heads are dispersed around the frame and there is a change of colour on both the board and the wood of the frame.

The subjects of these paintings are seascapes of notable areas of the coast on each side of Port Phillip Bay, south of Melbourne, Victoria. This painting is of Eagle Rock, Warrnambool, which is on the west of Port Phillip Bay. Eagle Rock is located about 400 metres west of Thunder Point, near Shelly Beach. The painting includes the rocky cliff formations looking east towards the Warrnambool Breakwater. The walk from the Thunder Point car park westwards to Shelly Beach has been popular over the decades with residents as well as tourists. Many photographs include the rock, with varying backgrounds depending on the angle of the camera. It is a popular dive site for locals and visitors, in calm weather! The site can be approached by boat from the open sea in favourable conditions, and there is plenty of native marine to be seen in this marine sanctuary. This part of Warrnambool’s rugged coastline is unprotected from the Southern Ocean with its wild icy winds and high seas. The painting’s crashing waves and the northerly direction of the smoke on the steamship sailing north show the effect of the southerly wind.

At the time of writing this mook T.J. Hoover was Professor of Mining and Metallurgy and Dean of the School of Engineering at Stanford University. Theodore Jesse Hoover, brother of the 31st President of the United States, was born in West Branch, Iowa, on January 28, 1871. He attended Stanford and received the Bachelor of Arts degree in Geology and Mining in 1901. Following graduation his professional career started with the position of assayer for the Keystone Consolidated Mining Company. After one year, he became assistant manager for the Standard Consolidated Mine, and a year later he was promoted to manager of the operation. In 1907 Hoover went to London as general manager of Minerals Separation, Ltd. This company was developing the froth flotation process for recovering minerals from ores. Hoover took an active part in the development of the flotation concentration process and authored one of the first books on the concentration of ores by flotation. After four years with Minerals Separation, Ltd., Hoover entered private practice as a consulting mining and metallurgical engineer with offices in London and in San Francisco. He was very successful and held positions of consulting engineer, managing director, director, and president of many mining companies in America, Europe, Asia, Africa, and Australia. He returned to Stanford in 1919 as Professor of Mining and Metallurgy and Executive Head of the Department of Mining and Metallurgy. His experience and ability in organization made him a natural leader. He was influential in the formation of the School of Engineering at Stanford. The School was formed in 1925 and he was made dean, a position he held until his retirement in 1936. As dean of engineering, he promoted a broad fundamental training program for undergraduate engineering students. Under his guidance, emphasis was placed upon graduate work and he was responsible for developing strong graduate engineering curricula at Stanford. While dean he continued teaching and his course, "The Economics of Mining," developed into a book which was published in 1933. He became interested in the functions of engineers and, with Professor Fish, wrote a book entitled "The Engineering Profession" which was published in 1940 and revised in 1950. In addition to his academic activities he was generous in his hospitality. Faculty and students alike enjoyed the annual field day and barbecue at his Rancho del Oso, near Santa Cruz. He was widely read and had a lively interest in all the things he encountered. He speculated on the antiquity of man and man's early production processes. To verify an idea regarding flint tools, he studied their shapes and became proficient in making arrow heads. He was also interested in wild life, and was one of the founding members of the Cooper Ornithological Society.
