This is a set of 30 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967. Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds.

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. The parts were from a carriage clock ca. 1878.

EXHIBITION in the DOME The Sea is All Around Us - Margaret Woodward 11-21 May 2015 Dome Gallery – Mission to Seafarers, 717 Flinders Street, Melbourne, Australia. 37 º 49'21" S 144º 57'03"E Hours: Daily 11.00am - 4.00pm The sea is all around us is a multi-layered event which will create a memorable experience for those visiting the Dome Gallery and the Mission to Seafarers in Melbourne’s Docklands. The event will acknowledge and raise awareness of the working lives and journeys of seafarers by making visible their role in transporting commodities, materials and objects to and from Australia’s shores. This installation invites seafarers and visitors to participate in a global project which aims to witness sea journeys and trace the mobile life of seafarers and souvenirs. For a fortnight in May 2015, the Dome Gallery will become an architectural large scale compass, with the circular floor marking the intersection of its latitude and longitude (37 º 49'21" S 144º 57'03"E). Over these two weeks the Dome Gallery will be inscribed with marks recording journeys made by seafarers, recording destination and departure ports, home lands and waterways, and in doing so making visible a small segment of the global patterns of seafaring. Custom-made souvenirs designed for the installation will be given to seafarers as gestures of welcome and a memento of their visit. The souvenirs originating in Poland will continue their journey by sea, to destinations beyond the Dome becoming part of the global network of seafaring, with an invitation for seafarers to record their future journeys using QR code scanning technologies. It is hoped that by releasing the 200 limited edition souvenirs accompanying the seafarers the mobile life of souvenirs and seafarers will also become visible. For more information visit the website: sensingtheremote.net Margaret Woodward is Associate Professor of Design at Charles Sturt University For a fortnight in May 2015, Margaret Woodward was ‘in residence’ at the Mission to Seafarers Norla Dome Gallery with her participatory installation project "The Sea is All Around Us". The floor of the gallery became a large scale compass. Seafarers were welcomed to the gallery their ships, journeys and destinations were recorded and mapped on the floor drawing. Seafarers were welcomed with cake and souvenir mugs of tea. These mugs, a momento for the seafarers, were inscribed with a scannable QR code and an invitation for seafarers to record their journeys on a dedicated project website. Around 120 souvenirs are now continuing their journey by sea and seafarers have scanned the mugs from locations including Singapore, Brisbane, Fremantle, Adelaide, Busan and Johor! After the exhibition Margaret Woodward was able to follow the seafarers' whereabout: ""The Sea is all Around Us". I am in awe of where this project might go, well done Margaret. One week has passed since finishing up at the Mission to Seafarers Victoria. Today I check my website and can see that the cup-carrying seafarers are reaching warmer climates, they tell me it’s getting hot as some are already in Suva and Port Lautoka. I’ve watched the souvenirs travel and fan out from Melbourne, some West to Adelaide and Fremantle, others going north to Sydney Brisbane, Singapore and Busan. Another seafarer scans in from Changi Airport, excited to be going home for some time with his family in the Phillipines. I keep an eye on my ‘fleet’ of 22 ships that visited the Dome Gallery, and see where they are on the Live Shipping website, watch some of them sail up the coast of Western Australia and marvel at the steady pace this journey takes. I am so used to flying over coastlines and countries in a matter of hours, impatiently watching the tracking screen from my airline seat, this shipping pace seems so much more real, so much more of a passage. I feel connected to these ships, to the people on board, to know that an object has passed from my hands to theirs, now holding in it my cargo of concern."margaret woodward, installation, exhibition, norla dome, 2015, sea voyage, sea journey, cultural events

An hourglass or sandglass is an instrument for measuring a defined time and can be used perpetually by simply turning it over immediately the top bulb empties. The clear blown glass is shaped into two equal sized bulbs with a narrow passage in the centre and contains uniform sized sand or glass particles in the lower bulb. The width of the neck regulates the constant flow of the particles. The glass is held in a stand with top and bottom of equal shape and size. Hourglasses can measure an infinite variety of time by gauging the size of the particles, the shape and size of the bulbs and the size of the passage between the bulbs, thus measuring hours or minutes or even seconds. Generally an hourglass sits between discs of wood at the ends, which are joined by long wooden spindles between the ends and tightened by screw caps. The length of time can be adjusted by adding or removing sand particles. The use of the marine sandglass (or hourglass) has been recorded in the 14th century in European shipping. A one minute sandglass was used in conjunction with the ship’s log for ‘dead reckoning’, (see below) that is, for measuring the ship’s speed through the water. They were also used to regulate ringing the ship’s timetable; for example a 4 hour sandglass was used for the length of the sailors’ watch, and a half hour timer for taking of readings for the ship’s log; the ship’s bell would be rung every half hour. It was usually the role of the cabin boy to watch and turn the sandglasses over at the exact time of them emptying their upper chambers and to ring the ship’s bell. Hourglasses have been used historically for many hundreds of years. Some have been used for timing church sermons, in cooking, in industry and at sea. Even today they are used for measuring the cooking time of eggs and timing a player’s turn in games such as Boggle and Pictionary. The sandglasses at sea were gradually replaced in the late 1700’s to early 1800’s by the more accurate chronometers (marine clocks) when they became reliable instruments. DEAD RECKONING (or Deduced Reckoning) Dead reckoning is the term used to describe the method of calculating the ship’s position from its speed and direction, used in early maritime travel, mostly in European waters. Both the (1) speed and the (2) direction of travel were recorded on a Traverse Board at half-hourly intervals during a helmsman’s watch of 4 hours. The navigator would record the readings in his ship’s log, plot them on his navigational chart and give his updated course directions to the next helmsman on watch, along with the cleared Traverse Board. This was a very approximate, but none-the-less helpful, method of navigation. The wooden Traverse Board was a simple pegboard with a diagram of a compass with eight peg holes along the radius to each of the compass points, plus a grid with ascending half hours in the left column and increasing ship’s speed in knots in a row across the column headings, with a peg hole in each of the intersecting cells. A number of wooden pegs were attached to strings on the board. By placing one peg consecutively in the direction’s radius hole, starting from the centre, and the speed holes when the half hourly reading was taken, a picture of speed and direction for the whole 4 hour watch was created. (1) To measure the ship’s speed a one minute hourglass timer was usually used to measure the ship’s speed through the water and help to calculate its longitude. A rope, with knots at regular standard intervals and a weight such as a log at the end, would be thrown overboard at the stern of the ship. At the same time the hourglass would be turned over and a seaman would start counting the number of knots on the rope that passed freely through his hands as the ship travelled. When the timer ran out the counting would be stopped. A timer of one minute (one-sixtieth of an hour), knots spaced one-sixtieth of a nautical mile apart, and simple arithmetic easily gave the speed of the ship in nautical miles per hour ("knots"). This would be recorded every half hour. The speed could however be inaccurate to the travel being affected by ocean currents and wind. (2) To calculate the ship’s direction a compass sighting would be recorded each half hour.Marine hourglasses or sandglasses were used from around the 14th to 19th century during the time of sailing ships. This hourglass is representative of that era, which is during the time of the colonisation of Australia. Hourglass or sandglass; an instrument used to measure time. Two equal sized clear glass bulbs joined with a narrow passage between them, containing equal sized particles of sand grains in lower bulb.

This document, also referred to as a word picture or Tablet, is framed in glass and timber with gilt trim, is handwritten with colour highlights. The penned letters rest on ruled guide lines, decorated where the lines intersect. The writing gives a description of the state of Borough of Warrnambool around 1875; its location, the area it covers, its population, Harbour and facilities, public buildings and institutions, imports and exports, financial worth, number of houses, connection with other areas of the Colony. A possible reason and origin for the document is found in an article ‘Link with US Exhibition’ from the Warrnambool Standard of December 19, 1981, written by local historian Bruce Morris. The writer mentions that the Warrnambool Borough Council met on 15th June 1875 and recorded a letter from G.C. Levey , secretary to the Melbourne group of commissioners representing the Colony, and Victoria in particular, for the Philadelphia Centennial Exhibition of 1876. The letter asks Council to provide “statistics as to the population, social condition and commercial and industrial state of the district in and around Warrnambool.” A sub committee was formed for the project. The Mayor, Cr. Thomas King, wrote and signed a Report, presented to the council on July 14, 1875, in which “The Committee … begs to recommend that a Tablet be prepared setting for the particulars respecting the following matters relating to the Borough”. The matters included area, population, annual income, churches, schools, other public buildings, societies and companies, general description of houses erected, and returns of exports and imports for 1874. The minutes note that the Report was adopted. The article above also notes the opinion of Warrnambool printers who have examined the document; it is almost certainly to be an old lithograph, which means there could be several copies. It is possible that there may be a copy in Melbourne and another in Philadelphia. It is interesting to note that (1) the quoted location co-ordinates are for an “Unnamed Road, Packsaddle NSW 2880, Australia”, and that the DMS co-ordinates for Warrnambool’s Council Offices differ, being 38.23.9.12 South, 142.28.52.887. (2) the date for “Exports and Imports for the Year Ending 30th June 1875” is different to the period mentioned by Cr. King in the sub committee’s Report of recommendation “returns of exports and imports for 1874”. The information required to have the figures for the end of June 1875 would need to have been compiled very quickly for the Tablet to be ready for the opening of the Philadelphia Exhibition on 10 May 1876.

Coaches run to and from the Metropolis daily, in connexion [connection] with the Railway of Geelong and Steamers belonging to Local Companies sail between Melbourne, Warrnambool, Belfast [renamed Port Fairy], and Portland several times weekly. The Harbour is known as Lady Bay, and is partially protected by a reef of rocks stretching from the mouth of the Hopkins River. The formation of a Breakwater has been decided upon by the Government, to extend 600 yards, at an estimated cost of £100,000. There are two substantial Jetties, one of 800 and the other of 600 feet in length. The former is connected with the Town by means of a Tramroad, along which Goods, inwards & outwards, are conveyed, & the latter has been constructed solely for the purpose of facilitating the transit of material for the formation of the Breakwater. In addition to the trade of the Borough and District, the principal Townships up country receive their supplies from Melbourne and ship their exports through Warrnambool. Potatoes form the staple produce of the district, and the richness of the soil can be estimated by the fact that the Government Statistics for 1875 give as the average yield a return of Seven Tons to the acre. Several thousand acres between Warrnambool and Tower Hill are now being laid down in Potatoes by Tenants who have leased the lands at rates up to £5 per acre for the season 1875-6.
