Probably acquired for use in Telegraphy courses run at the Ballarat SChool of Mines between 1875 and 1893. Telegraph relays amplified electrical signals in a telegraph line. Telegraph messages traveled as a series of electrical pulses through a wire from a transmitter to a receiver. Short pulses made a dot, slightly longer pulses a dash. The pulses faded in strength as they traveled through the wire, to the point where the incoming signal was too weak to directly operate a receiving sounder or register. A relay detected a weak signal and used a battery to strengthen the signal so that the receiver would operate. This relay was made by the firm of Charles T. and John N. Chester, two brothers who successfully partnered in New York City. Charles (1826-1880) founded the firm and provided the expert telegraphy knowledge while John (1820-1871) kept the books and managed the business operations.(http://americanhistory.si.edu/collections/search/object/nmah_706518, accessed 25/01/2018)Electromagnetic relay device used in telegraphy.

After a special meeting of the Ballarat SChool of Mines Council in 1874, a decision was made to offer instruction in Telegraphy, a subject not directly related to mining. Telegraphy was taught by W.P. Bechervaise, postmaster at Ballarat. On 07 October 1874 the Ballarat Courier correspondent reprted on Telegraphic training: "... these classes ... are a snare and a delusion, as there is scarcely the remotest chance of obtaining employment when the examination has been passed."scientific instrument, telegraph relayer, telegraphy relay device, telegraphy

Opera Glasses came into existence as a result of a long line of inventions, and further improvements upon those inventions. The process started in the year 1608 when a Dutch optician by the name of Hans Lipperhey developed the first pair of binoculars with a magnification capability of X3. Less than a year later, a well-known inventor and philosopher by the name of Galileo developed what became known as the Galilean telescope. Advertisements were first found for opera glasses and theatre binoculars in London as early as 1730 in the form of a long collapsible telescope. The "Opera Glass" as it was referred to; was often covered in enamel, gems, ivory, or other art and paintings. For almost 100 years opera glasses existed merely as telescopes. In Vienna, in 1823 the first binocular opera glasses and theatre binoculars began to appear. They were two simple Galilean telescopes with a bridge in the centre, each telescope focused independently from the other by extending or shortening the telescope until the desired focus was achieved, which was useful, yet very cumbersome. Two years later in Paris, Pierre Lemiere improved on this design and created a centre focus wheel. This allowed the focusing of both telescopes together. After this development, opera glasses and theatre binoculars grew in popularity because of the superior view they facilitated in opera and theatre houses. The beautiful design of the glasses themselves also added appeal to the opera-going crowd. By the 1850's opera glasses and theatre, glasses had become a must-have fashion accessory for all opera and theatregoers. A vintage pair of 1920s opera glasses probably made in France by an unknown maker the item is significant due to it's provenance that can be traced and it's completeness as a useful social item and fashion accessory used by theatergoers from the mid 19th century and well into the 20th century.

The ship's log part, called a fish, is likely to be from a mechanical taffrail log system. It was recovered from the wreck site of the barque, the 1840-1852 Grange. There are no marks on the fish to identify its maker or model. It is part of the John Chance Collection. This ‘fish’ is part of an early to mid-1800s ship's log. It would likely have been part of a taffrail log connected to a rotor (also called propeller, spinner) by a strong line, and the other end connected by a line to a dial mounted on the taffrail, or stern rail, at the stern of the vessel. As the propeller rotated through the water it would spin the log, which in turn would cause a number to register on the dial, showing the current speed in knots; one knot equals one nautical mile per hour. TAFFRAIL LOGS A taffrail log is a nautical instrument used for measuring the speed of a vessel, providing vital navigational information to be calculated, such as location and direction. A log has been used to measure the speed of a vessel since the 1500s. A simple piece of wood was tied to a long line and thrown into sea at the back of the vessel. The rope was knotted all along at equal distances apart. On a given signal the log line was pulled back into the vessels, the knots counted until the log came up, then the figures were calculated by a navigator In 1802 the first successful mechanical log available for general use was invented by Edward Massey. It had a rotor 'V' section connected to a recording mechanism. The water’s movement rotated the rotor, which intern sent the movement to the recorder. There are examples of this invention available to see in some of the maritime museums. Thomas Walker, nephew of Edward Massey, improved on Massey’s design, and Walker and his son took out a patent on the A1 Harpoon Log. In 1861. Both Massey and Walker continued to improve the designs of the taffrail log. New designs were still being introduced, even up to the 1950s. THE GRANGE, 1840-1858- The wooden barque ’Grange’ was a three-masted ship built in Scotland in 1840 for international and coastal trade. On March 22, 1858, the Grange set sail from Melbourne under Captain A. Alexander, carrying a cargo of ballast. The barque had left the Heads of Phillip Bay and was heading west along the Victorian coast towards Cape Otway. The ship struck Little Haley’s Reef at Apollo Bay due to a navigational error and was stuck on the rocks. The crew left the ship carrying whatever they could onto the beach. Eventually, the remains of the hull, sails and fittings were salvaged before the wreck of the Grange broke up about a month later. About 110 years later, in 1968, the wreck of the Grange was found by divers from the Underwater Explorers Club of Victoria. They were amazed to find a unique, six to nine pound carronade (type of small cannon) and a cannonball on the site. There have been no other similar carronades recorded. In that same year the anchor of the Grange was recovered by diver John Chance and Mal Brown. The ship’s log is significant historically as an example of hardware used when building wooden ships in the early to mid-19th century. The ship’s log is historically significant as an example of the work and trade of blacksmith. The ship’s log also has significant as it was recovered by John Chance, a diver from the wreck of the Grange in the 1968. Items that come from several wrecks along Victoria's coast have since been donated to the Flagstaff Hill Maritime Village’s museum collection by his family, illustrating this item’s level of historical value. The ship’s log is historically significant for its association with the 1840s wooden barque, the Grange. The Grange is an historical example of a Scottish built vessel used for international and coastal trader of both cargo and passengers in the mid-19th century. The Grange is an example of an early ship, designed with a wooden hull. It is significant as a ship still available to divers along the south coast of Victoria, for research and education purposes. The Grange is an example of a mid-19th century vessel that carried a weapon of defence onboard. Ship log fitting, called a fish; part of a brass navigational instrument, likely to be from a taffrail log. The metal is a tan colour and has rough surface with a sheen, and discolouration in places. Its basic shape is a hollow cylinder with ends tapering to a smaller size. In the centre there are opposing openings cut out, showing a rough texture inside. One end on the cylinder is closed with a ring and shank installed, fixed by an embedded screw through the end of the cylinder.

HISTORY OF THE LOCH ARD The LOCH ARD belonged to the famous Loch Line which sailed many ships from England to Australia. Built in Glasgow by Barclay, Curdle and Co. in 1873, the LOCH ARD was a three-masted square rigged iron sailing ship. The ship measured 262ft 7" (79.87m) in length, 38ft (11.58m) in width, 23ft (7m) in depth and had a gross tonnage of 1693 tons. The LOCH ARD's main mast measured a massive 150ft (45.7m) in height. LOCH ARD made three trips to Australia and one trip to Calcutta before its final voyage. LOCH ARD left England on March 2, 1878, under the command of Captain Gibbs, a newly married, 29 year old. She was bound for Melbourne with a crew of 37, plus 17 passengers and a load of cargo. The general cargo reflected the affluence of Melbourne at the time. On board were straw hats, umbrella, perfumes, clay pipes, pianos, clocks, confectionary, linen and candles, as well as a heavier load of railway irons, cement, lead and copper. There were items included that intended for display in the Melbourne International Exhibition in 1880. The voyage to Port Phillip was long but uneventful. At 3am on June 1, 1878, Captain Gibbs was expecting to see land and the passengers were becoming excited as they prepared to view their new homeland in the early morning. But LOCH ARD was running into a fog which greatly reduced visibility. Captain Gibbs was becoming anxious as there was no sign of land or the Cape Otway lighthouse. At 4am the fog lifted. A man aloft announced that he could see breakers. The sheer cliffs of Victoria's west coast came into view, and Captain Gibbs realised that the ship was much closer to them than expected. He ordered as much sail to be set as time would permit and then attempted to steer the vessel out to sea. On coming head on into the wind, the ship lost momentum, the sails fell limp and LOCH ARD's bow swung back. Gibbs then ordered the anchors to be released in an attempt to hold its position. The anchors sank some 50 fathoms - but did not hold. By this time LOCH ARD was among the breakers and the tall cliffs of Mutton Bird Island rose behind the ship. Just half a mile from the coast, the ship's bow was suddenly pulled around by the anchor. The captain tried to tack out to sea, but the ship struck a reef at the base of Mutton Bird Island, near Port Campbell. Waves broke over the ship and the top deck was loosened from the hull. The masts and rigging came crashing down knocking passengers and crew overboard. When a lifeboat was finally launched, it crashed into the side of LOCH ARD and capsized. Tom Pearce, who had launched the boat, managed to cling to its overturned hull and shelter beneath it. He drifted out to sea and then on the flood tide came into what is now known as LOCH ARD Gorge. He swam to shore, bruised and dazed, and found a cave in which to shelter. Some of the crew stayed below deck to shelter from the falling rigging but drowned when the ship slipped off the reef into deeper water. Eva Carmichael had raced onto deck to find out what was happening only to be confronted by towering cliffs looming above the stricken ship. In all the chaos, Captain Gibbs grabbed Eva and said, "If you are saved Eva, let my dear wife know that I died like a sailor". That was the last Eva Carmichael saw of the captain. She was swept off the ship by a huge wave. Eva saw Tom Pearce on a small rocky beach and yelled to attract his attention. He dived in and swam to the exhausted woman and dragged her to shore. He took her to the cave and broke open case of brandy which had washed up on the beach. He opened a bottle to revive the unconscious woman. A few hours later Tom scaled a cliff in search of help. He followed hoof prints and came by chance upon two men from nearby Glenample Station three and a half miles away. In a state of exhaustion, he told the men of the tragedy. Tom returned to the gorge while the two men rode back to the station to get help. By the time they reached LOCH ARD Gorge, it was cold and dark. The two shipwreck survivors were taken to Glenample Station to recover. Eva stayed at the station for six weeks before returning to Ireland, this time by steamship. In Melbourne, Tom Pearce received a hero's welcome. He was presented with the first gold medal of the Royal Humane Society of Victoria and a £1000 cheque from the Victorian Government. Concerts were performed to honour the young man's bravery and to raise money for those who lost family in the LOCH ARD disaster. Of the 54 crew members and passengers on board, only two survived: the apprentice, Tom Pearce and the young woman passenger, Eva Carmichael, who lost all of her family in the tragedy. Ten days after the LOCH ARD tragedy, salvage rights to the wreck were sold at auction for £2,120. Cargo valued at £3,000 was salvaged and placed on the beach, but most washed back into the sea when another storm developed. The wreck of LOCH ARD still lies at the base of Mutton Bird Island. Much of the cargo has now been salvaged and some was washed up into what is now known as LOCH ARD Gorge. Cargo and artefacts have also been illegally salvaged over many years before protective legislation was introduced. One of the most unlikely pieces of cargo to have survived the shipwreck was a Minton porcelain peacock - one of only nine in the world. The peacock was destined for the Melbourne International Exhibition in 1880. It had been well packed, which gave it adequate protection during the violent storm. Today, the Minton peacock can be seen at the Flagstaff Hill Maritime Museum in Warrnambool. From Australia's most dramatic shipwreck it has now become Australia's most valuable shipwreck artefact and is one of very few 'objects' on the Victorian State Heritage Register. Flagstaff Hill’s collection of artefacts from LOCH ARD is significant for being one of the largest collections of artefacts from this shipwreck in Victoria. It is significant for its association with the shipwreck, which is on the Victorian Heritage Register (VHR S417). The collection is significant because of the relationship between the objects, as together they have a high potential to interpret the story of the LOCH ARD. The LOCH ARD collection is archaeologically significant as the remains of a large international passenger and cargo ship. The LOCH ARD collection is historically significant for representing aspects of Victoria’s shipping history and its potential to interpret sub-theme 1.5 of Victoria’s Framework of Historical Themes (living with natural processes). The collection is also historically significant for its association with the LOCH ARD, which was one of the worst and best known shipwrecks in Victoria’s history.

The clock parts were discovered in 1980 by Julie Wilkins, a Victorian scuba diver who had already experienced more than 500 dives in Australia and overseas. She was holidaying in Peterborough, Victoria, and looking forward to discovering more about the famous Loch Ard ship, wrecked in June 1878 at Mutton Bird Island. The fast Glasgow-built clipper ship was only five years old when the tragedy occurred. There were 54 people on board the vessel and only two survived Julie's holiday photograph of Boat Bay reminds her of her most memorable dive. Submerged in the calm, flat sea, she was carefully scanning around the remains of the old wreck when, to her amazement, a gold coin and a small gold cross suddenly came up towards her. She excitedly cupped them in her hands and then stowed the treasures safely in her wetsuit and continued her dive. She soon discovered a group of brass carriage clock parts and some bottles of champagne. It was a day full of surprises. The items were easily recognisable, without any build-up of encrustations or concretion. Julie secretly enjoyed her treasures for twenty-four years then packed them up for the early morning train trip to Warrnambool. After a short walk to Flagstaff Hill Maritime Museum and Village, her photograph was taken as she handed over her precious find. She told her story to a local newspaper reporter, lunched a café in town then took the late afternoon train home. Her generous donation is now part of a vast collection of Loch Ard shipwreck artefacts, including the gold watch and the Minton Majolica model peacock. This group of brass clockwork parts is incomplete. The pieces were in the ocean for over 100 years before Julie recovered them from the Loch Ard wreck. Their size would suit the works of a carriage clock, with a mainspring and weight to power the clock movement, a pendulum to measure the clock's speed, arbours, posts, pillars and at least one other plate. They would have been mounted inside a protective case with a small door to easily access the clock face for setting the time and accessing the key's winding hole. The clock cases were usually made from decorative gilt brass with a glass front and a carrying handle. The parts include a weighted second hand with a decorative four-pronged finish at one end, a rounded weight at the other, and a hole for attaching it to the clock face. The gear teeth profiles are ‘cycloidal’, an arch shape with vertical sides, which is common for antique clocks. Modern clockworks have ‘involute’ teeth with sloping sides and a squared-off top. The brass carriage clock parts are an example of a mechanical clock produced in the 1870s. The clock's design is a part of the chain of technological improvements in methods for timekeeping. Its cycloidal gear teeth were the forerunner of the more modern involute gears. The group of clock parts includes a weighted hand or arm for signifying the seconds. This feature was uncommon in portable Victorian-era clocks. The clock parts are also significant for their association with the ill-fated sailing ship Loch Ard, wrecked in 1878. The travelling clock or officer’s clock may have been part of the cargo destined for the 1880 Melbourne Exhibition, or the personal possession of one of the people on board the vessel. Brass clockwork parts from a mechanical clock, sixteen pieces. Parts comprise a plate, large gears or wheels, small pinions or wheels with fine teeth, wheels with cogs, and a weighted second hand.

This chronometer was made around 1936 and has been on display at Flagstaff Hill for over 40 years as part of the exhibit of the ‘Reginald M’, an Australian-built, 19ss, coastal trader vessel. A chronometer is an accurate mechanical instrument used for measuring time. It is constructed carefully to remain stable even under the changing conditions of seafaring life such as temperature, humidity and air pressure. The Master or Navigator of a ship could use the chronometer and the positions of celestial bodies to calculate the ship’s latitude at sea. In 1905 the business Chronometerwerke GmbH was formed in Frankfurt, Germany, to supply the country with high-quality mechanical chronometers and ship clocks for their maritime trade, making the country independent of other international suppliers such as those in England. In 1938 the firm was renamed Wempe Chronometerwerke. The business continues today. Its products now include its well-known chronometers, battery-powered ship clocks, ship’s bell clocks, barometers, barographs, thermometers, hygrometers, comfort meters to measure temperature and humidity, and wristwatches. The company also performs chronometer testing facilities for the State’s Weights and Measures office. The article written by Givi in July 2022 “The Basics of Marine Meteorology – a Guide for Seafarers” refers to the weather’s signs and patterns being repeated over and over, and the recording of these observations helps forecasters predict changes in the weather. The chronometer is an example of a mechanical navigational marine instrument in use in the early to the mid-20th century. The maker is significant as part of a German government initiative to be self-sufficient in the production of good quality marine technology. This chronometer is significant as part of the exhibit, the Australian-built vessel, 1922 coastal trader ‘Reginald M’, listed on the Australian Register of Historic Vessels and on display for over 40 years.Marine chronometer or marine clock, brass case, glass cover, Roman numerals, 24-hour numbers beside them.
