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.

The brass wall clock retains its key. It was provided by the Department of Shipping and Transport in about 1900 and is original to the lightstation. It was mounted in the watchroom, a small extension at the front of the lighthouse (later radar station), where lightkeepers completed many of their reports and recorded radio schedules, weather observations, distress calls and other data. Good, reliable clocks were also essential for maintaining a strict roster of hours for winding the clockwork mechanism that kept the lens active. The name of the clock’s manufacturer has not been determined. More specifically it was used for logging radio schedules that were made at five minutes to midday, everyday, and for recording the times of weather observations, distress and any other calls that came in. AMSA notes that ‘Lightkeepers who used this clock were said to have polished and wound it every week while it was in use until the 1990s when its otherwise impeccable time keeping mechanisms finally became inaccurate’.The brass clock at Wilsons Promontory illustrates the importance of timekeeping in a nineteenth century lighthouse. Despite its slightly chipped face, the timepiece has first level contributory significance for its historic association with the watch room and confirmed provenance. The significance of this clock also lies with its complete provenance..1. Brass clock with a circular white face and black roman numerals. Three brackets at back to attach to wall.

John Gall Mainlands father John Mainland Snr. was born in 1835 in the town of Lerwick in the Shetland Isles off the coast of Scotland. At the age of fifteen, he migrated to the South Island of New Zealand where he trained as a carpenter/builder after settling in Oamaru where he soon became a prominent citizen. He was for many years the Chairman of the Hospital Board and Captain of the fire brigade (which he founded). Mary Gall, Johns wife had also migrated with her family from Glasgow Scotland in 1837 at the age of thirteen to New Zealand where she had met and married John Mainland and in 1866 John Gall Mainland the second eldest of their six children was born. After John Gall Mainland Jnr. had trained as a jeweller and watchmaker he also developed itchy feet and left New Zealand for Australia in the late 1880s eventually settling in Walhalla Victoria where he became chief of the fire brigade for ten years before moving to Warrnambool. Gertrude Emily born 1872 met and married John G Mainland after he had increased his skills to become an optician. In Jan 1892 opened a business in Liebig St Warrnambool the sign outside his premises read, (J Mainland Watchmaker Jeweler and Optician). While he was establishing his business and profession John had set about contributing to the cultural and business life of the Warrnambool community. One of his many community commitments was with the scouting movement where he became a King Scout and an original charter member of the Warrnambool Rotary Club.The clock was made by an early Warrnambool business identity who had also made an important contribution to the local community over the years through his involvement with Rotary as a founding member the fire brigade. Having an item that was made by John Mainland during the early development of Warrnambool and in such good condition is in itself significant, it's provenance is well established and it is another piece of local history that further tells a story of Warrnambool's cultural life and early development in the 1890s.

From the Wyuna, a twin-screw diesel electric pilot cutter. Introduced in 1953 and served with the Port Phillip Sea Pilots until 1979.The MV Wyuna served as a Pilots tender from 1953 to 1979 before fast pilot boats were introduced. During this time the Wyuna would lower a work boat to transfer a pilot onto a ship which would have had to come to a full stop to allow transfer, thus losing time and extra fuel. Today the fast pilot boats come along side a still moving vessel to allow pilot access outside Post Phillip Heads. Brass ships clock from galley of pilot vessel Wyuna.

The Seth Thomas Clock Company was founded in 1813 by renowned American clockmaker Seth Thomas (1785-1859) of Connecticut, USA, and pioneered the mass production of clocks. After Seth Thomas's death, his son, also Seth Thomas (1816-1888), continued operating the business. Their 'Adamantine' model was released in many variations. This particular model features two pillars on either side of the clockface, however other Adamantine variants could have none or up to three or four half-pillars on either side. This style of black mantle clock appears to be inspired by French clocks of the 1860s, which had gained popularity in the United States. While those clocks were often made with onyx, slate, or marble, Seth Thomas uses a durable celluloid veneer named Adamantine over a wood case to replicate the appearance of the original materials. This object is representative of the innovative manufacturing processes of pioneering clockmaker Seth Thomas and his company.

The New Haven Clock Company from Connecticut, USA, was incorporated by clockmaker Hiram Camp (1811-1893) in 1853. Camp studied clockmaking under his uncle Chauncey Jerome (1793-1868) from the age of 17. New Haven Clock Company supplied brass clock movements to Chauncey Jerome's own business, Jerome Manufacturing Company, until that company declared bankruptcy two years later. New Haven Clock Company acquired Jerome Manufacturing Company and continued to manufacture clocks for over a century. They grew to such a scale that they were outproducing all other clockmakers in the state of Connecticut. Their 'Duna' model was created circa 1881 and features a solid walnut cabinet with ornate carvings and a glass door decorated in gold, black, and red detail. The 8-day clock is designed to be wound once per week with a key; the clock features instructions on the reverse side should the timing need adjustment.This object is part of the Burke Museum Collection and represents the detailed craftmanship of one of the leading clock manufacturers of the late nineteenth and early twentieth centuries.Decoratively carved and etched wooden eight day striking mantle clock with a white face and black roman numerals.Engraving on rim above clock face: PATD FEB.11.1879 Engraving on pendulum: PAT'D MCH.1st 1881 Reverse label: 8 Day Duna / STRIKING./ New Haven Clock Co., / NEW HAVEN, CONN. / NOTICE. / If the Clock should go too fast, lower the ball ; / if too slow, raise it.
