The cylindrical cardboard container with lid formerly contained a ventometer, a small simple tool for measuring wind speed. It consisted of a clear tube containing a small diaphragm which had a hole in the bottom for wind to enter. Once the wind entered the tube it pushed up the diaphragm, indicating the rate of velocity. Ventometers were common devices that have since been replaced by more sophisticated measuring equipment, such as digital air speed meters. Further information on this particular example, including perhaps the name of the manufacturer, may survive on the container but this has not been recorded. The small simple tool for measuring wind speed pre-dates the electronic devices at Gabo Island.Tubed shaped cardboard container with lid to house instrument for measuring.

This Tangye B-size, single-cylinder, horizontal steam engine was likely manufactured in England around the mid-1880s. It was distributed by Melbourne machinery merchants Cameron & Sutherland, which also operated in Bendigo and Ballarat. A local cheese maker once used the engine to drive factory equipment. It was later donated to the Warrnambool Technical School, which then donated it to Flagstaff Hill to add to its historical steam engine collection. Between its manufacture and its donation to Flagstaff Hill, the governor had been replaced by the current Pickering governor. This engine design was very popular in the late 19th and early 20th centuries. When connected and powered up, the engine could drive an overhead line shaft via a flat belt off its flywheel. The line shaft would then drive the machinery via flat belts. It could drive virtually any type of machinery, such as water and sewerage pumps, mine elevators, winches, cranes, metal forges, air blowers, and marine machinery. This engine features a mechanical governor, which controls the speed of the engine regardless of whether it is under load. It also has a water pump built into the valve rod, which is used to supply the boiler with water. Steam enters the cylinder via a slide valve and applies pressure to the piston; it is like a modern internal combustion engine, but in the case of the steam engine, the pressure is exerted in turn on either side of the piston. In other words, the connecting rod is pushed by steam via the piston and piston rod and then pulled back again by steam pushing on the opposite side of the piston. Thus, power is exerted almost continuously, except at the end of each piston stroke, when it reverses direction. In the 1880s, many local butter and cheese manufacturers installed Tangye steam engines to power their machinery. A comprehensive article in the Gippsland Mercury in September 1889 extolled the magnificence of the Farnham Butter Factory in Dennington, Warrnambool, and described how one Tangye engine was used to drive several machines in the cheese- and butter-making processes. A report in the Warragul Guardian in December 1890 notes that the newly opened Warrnambool Butter Factory used a Tangye steam engine to pump water from a 60-foot well. Tangye: Richard Tangye (1833–1906) and four of his brothers—James, Joseph, Edward, and George—were the sons of Joseph Tangye, a Quaker Cornish miner. In 1857, they founded the engineering firm Richard Tangye & Brothers in Birmingham, UK. In 1860, the firm became Tangye Brothers and moved to Cornwall Works in Birmingham. The business encouraged inventors to join the company and develop their patents there, as happened with Weston’s differential pulley block, invented by the Englishman Thomas Aldridge Weston in 1854. Tangye bought the patent in 1858, giving the firm the sole right to manufacture it. The design received a medal for “original application, practical utility and success” at the 1862 International Exhibition in London. Also in 1858, the Tangye firm was commissioned by Brunel’s shipping company to manufacture hydraulic lifting jacks, or rams, to launch the steamship SS Great Eastern. The success of this project brought favourable attention to the firm, and it became involved in other notable projects, including the erection of Cleopatra’s Needle in London in 1878 and work on the Forth Road Bridge in Scotland. The firm underwent several name changes over the years, including James Tangye and Brothers (1857), Tangye Brothers and Price (1859), Tangye Brothers (1860), Tangye Brothers & Holman (1876), Tangye Brothers (by 1878), Tangye Ltd. (1881), and then simply Tangye. Its machinery and equipment were exported worldwide. In 1884, a branch with showrooms, offices, and a warehouse was opened in Melbourne at Cornwall House, Collins Street West. The firm was well known for producing high-quality machinery for agriculture and industry. Even today, new Tangye machinery is available for a subsidiary of Allspeeds. An extensive account of the firm’s history, names, inventions, and further references is available in Grace’s Guide, which also includes references to and diagrams of the Tangye horizontal steam engine. The horizontal steam engine was made by the well-known engineering firm Tangye, known for its high quality of manufacture. It was an important development in machinery because it helped improve productivity. Engines of this type are still used in some parts of the world today. This engine is a good example of a late 19th-century steam engine used in industry and agriculture and adapted for many different purposes. It is also important locally because it was connected to a local cheese making business and part of the thriving western district dairy industry. It may have been one of the Tangyes engines used at the Farnham butter factory or the Warrnambool Butter Factory, which was reported to be one of the most important in the Colony. It is also connected to the Warrnambool Technical School, established in 1968. Steam engine: stationary Tangye Size B, single-cylinder, horizontal Mill type steam engine.

Harold Gatty was born on January 5th, 1903 in Campbell Town, Tasmania. He was a navigator and aviation pioneer. He began his career learning navigation at the age of 14 as a midshipman at the Royal Australian Naval College but withdrew after three years and became an apprenticed ship's officer with the Patrick Steamship Company of Sydney. After W. W. 1 he joined the Australian Merchant Navy where he learned the constellations while standing night watch and became an expert in celestial navigation while serving on many ships sailing between Australia and California. In 1927 he moved to California and opened a navigation school and also a laboratory repairing navigational equipment. At this time he became very interested in air navigation and was aware of the limitations of existing methods and instruments for aerial navigation. He began researching ways of improving aerial navigation. Two early inventions of his were his air sextant and a ground speed and drift indicator which formed the basis of the automatic pilot which later came to be standard equipment on most aircraft. He worked with several record breaking pilots including Ann Morrow Lindbergh (who went on to serve as a navigator for her husband Charles Lindbergh), helped Wiley Post break the world record circumnavigating the Earth, invented a new method of "dead reckoning" that revolutionised the ability to fly safely through cloudy conditions without drifting off course and famously navigated a small plane (whilst trying to cross the Pacific) over 1900 km through fog (with no radio) and using only his dead reckoning techniques, back to their starting point in Japan after they developed fuel problems. In 1932 Gatty received the Distinguished Flying Cross from President Hoover. In 1934 Gatty formed the South Seas Commercial Company with Donald Douglas with the aim to deliver air services to the islands of the South Pacific. The Company was sold to Pan Am but he continued to work for them. In 1935 he went on a sailing expedition investigating several small islands in the South Pacific and was briefly marooned on Baker Island. He was able to use his extensive knowledge of seabird habits to save the crew. He was also very interested in the ability of the Polynesians to navigate using the stars. During the Second World War Gatty was given the honorary rank of Group Captain in the Royal Australian Air Force (RAAF) and worked for the U. S. Army Air Forces (USAAF) in the South Pacific. In 1943 he moved to Washington where he developed a survival book (The Raft Book) specifically for boat crews or air crews flying over the Pacific to help them survive and navigate their life rafts in remote areas of the ocean. The original book was 152 pages long however a condensed version was made which consisted of a 64 page booklet, combined map and star chart and calendar strip enclosed in a waterproof slipcase, to be placed in life rafts for emergency use. The booklet included navigational advice and ideas such as ocean currents, estimation of distance, using a compass, measurement of angles, recognising and steering by the stars, land indications from sea birds, migration of sea birds and insects, sounds from the land, the scent of the land and ocean currents and the colour of the sea etc. After W.W.2 Gatty moved to Fiji and formed Fiji Airways (which later became Air Pacific). Harold Gatty died in August 1957.The two copies of "The Raft Book" are significant as they are a written summary of the many methods of sea navigation (both modern and historical) that existed in the 1940's. They are also a record of Harold Gatty, who played a significant role in the development of modern day aerial navigation using his understanding of different sea navigational techniques.Two rectangular brown packets with waterproof coverings (oiled paper) titled "The Raft Book" by Harold Gatty. Each packet contains a folded 64 page paper booklet with detailed instructions for navigating a small craft in open seas, a folded chart (with a map of the world and oceans, well known constellations, latitude and longitude charts, Greenwich time and a scale for string lengths and Harp scale) and a long folded paper calendar strip.Front of package - "WATERPROOFED EDITION OF/ THE RAFT BOOK / By Harold Gatty / BOOK AND WORLD CHART / FOR / EMERGENCY NAVIGATION / To open envelope tear along above line.

The Ellenborough mine was located on Snob's Hill in Eaglehawk, near Bendigo, Victoria, Australia. It was a notable mine operating on the New Chum line of reef in the Eaglehawk District. The Ellenborough Mine was the first mine in the world to use electricity to light above and underground. On 12th October 1882, the installation of the lighting system was completed by the Australian Electric Light Company. 'The whole of the levels and back have been lighted so that candles have been dispensed with ....the engine house, blacksmith''s shop and brace are also lighted at night' (Bendigo Advertiser, 13th October, 1882). 'The electricity is generated in an ordinary electric battery placed in the engine-house, and driven by a three horse power " Soho" engine. This engine is supplied with steam by a pipe leading from the steam pipe used to supply the air-compressor. It can be driven at full power with a pressure of 351bs of steam, with the engine wheel moving at the rate of 220 revolutions per minute; the battery wheel makes 850 revolutions. The plant occupies very little space. The battery is a to-light machine; that is, it can supply sufficient electricity for 35 lights. Whether there is only one light burning or 35, there is no necessity to alter the machine or the speed, and there is no danger of one light becoming too powerful because all the rest are put out. There is no danger, as many people suppose, in taking hold of the wires, even if uncovered, for the engineer last evening plainly demonstrated that where the shock was greatest it was very mild, and could hardly be felt'.Handwritten copy of a report in the Bendigo Advertiser 24/5/1907. ''Serious break in Water Main which is situated about 100 yards south of the mine. Main service pipe which supplies Harvey town has been leaking for some time past.

In 1969 Private David Fisher, a national serviceman serving with 3 Squadron SAS, became the next soldier declared missing in action. In September 1969 Fisher was second-in-command of a five-man, long range SAS patrol searching for signs of enemy activity near the Nui May Tao massif in south-eastern Long Khanh province. After patrolling for seven days in persistent rain, on 27 September the Australians had a series of sharp contacts with strong groups of Viet Cong. Outnumbered and pursued through the jungle, they called for a helicopter extraction. The helicopters arrived within half an hour, just as the enemy were closing in on the SAS soldiers. During the hectic moments of the "hot" extraction, while under fire and surrounded by the enemy, the members of the patrol clipped on their karabiners and attached themselves to ropes dangling from a helicopter and were lifted clear of the jungle. As the helicopter gathered speed and helicopter gunships moved in to fire on the enemy on the ground, the patrol members suddenly noticed that Private Fisher was missing. He had fallen from his rope from a height of about 30 metres above the tree canopy. It was later suggested that, under pressure, Fisher may have attached his karabiner to the wrong loop on the rope. An air search began within ten minutes of the incident and a ground search began within five hours. A ten-man SAS patrol searched the jungle around the site, joined the following day by rifle companies who searched for the next six days. Fisher's body was never found, and he was declared missing in action, presumed dead. He had only two months remaining of his tour of duty.Stainless steel open-ended bracelet engraved with missing serviceman's full name and date missing.
