An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or "one-eighth of a circle," for the Octan'ts arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for celestial navigation. The estimation of this angle, is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. This fine octant once belonged to Captain Farquhar Chisholm and was donated by his granddaughter, Margaret Ruth Greer (nee Chisholm, born 1914). The label inside the Octant's box reads “Thomas L. Ainsley, Instrument Maker … etc”. Farquhar Chisholm was born in 1832 in Inverness, Scotland. He regularly sailed on perilous voyages between Quebec, Canada and the Baltic ports of Europe. In 1854 he migrated to Australia during the Gold Rush, to a place called Fiery Creek (near Beaufort Victoria) where he was fairly successful in his quest for gold. In the years of the Great Gold Rush, it was said that there were over 40,000 diggers in the goldfields of the Beaufort area! In 1857 having made sufficient money, he hired another crew and returned to Clachnacuddin, Inverness shire, Scotland and in that same year, he studied and obtained his Master Mariner Certificate (which would have included the use of an octant for navigation). He was appointed to Mr George (or James) Walker, as commander of his sailing ship, the 3-masted ELIZABETH, built 1859 and known as “The Walker barque”. In 1870 he married, then in 1887 returned to Australia with his wife and children (Kenneth Chisholm (1871), Mary Bremner Chisholm (1873), Margaret Hood Chisholm (1874), Farquhar Chisholm (1878)). They arrived in Port Melbourne, Victoria and sadly, only six weeks after landing, his wife Caroline passed away (in Geelong,1888). In 1900 Capt. Chisholm lived in Camperdown (Victoria) and not long after this his daughter Margaret died of consumption. In his later years, he went to live in the manse of St. Paul’s Presbyterian Church, Wangaratta, with his son, Rev. Farquhar Chisholm. He died there on Sat, 23rd March 1912, 80 years old. He was known as “… quiet, unobtrusive and competent, respected by all with whom he came in contact”. Some other members of Captain Chisholm’s family are; his older son Kenneth Chisholm, who was a contractor in Camperdown; a nephew Donald Macintosh (of 23 Douglas Row, Inverness); a grandson Brian Jones (son of Caroline Belle-Jones nee Chisholm, who lived in Camperdown in the earlier part of her life).The octant, the forerunner of the sextant, was a significant step in providing accuracy of a sailors latitude position at sea & his vessels distance from land when taking sightings of land-based landmarks.Octant, once belonging to Captain Farquhar Chisholm.

Author W M Smart, M.A., D.SC., F.R.A.S. (William Marshall Smart), (1889-1975) Regius Professor of Astronomy in the University of Glasgow, Instructor-Lieut. in the Royal Navy during World War I. and John Couch Adams Astronomer in the University of Cambridge. In 1943 he was elected as a fellow of the Royal Society of Edinburg. From 1949-1951 he was President of the Royal Astronomical Society and a member of the Royal Institute of Navigation. In 1958 he was awarded the Lorimer Medal of the Astronomical Society of Edinburgh. The publisher firm, Longmans, Green & Co, was originally founded in 1724 in London by Thomas Longman under the name Longman. In August of that year, he bought the two shops and goods of William Taylor and set up his publishing house there at 39 Paternoster Row. The shops were called Black Swan and Ship, and it is said that the 'ship' sign was the inspiration for Longman's Logo. After many changes of name and management, the firm was incorporated in 1926 as Longmans, Green & Co. Pty Ltd. The firm was acquired by Pearson in 1968 and was known as Pearson Longman or Pearson PLC. The book was sold by Collins Book Depot which was founded by Frederick Henry (Harry) Slamen in 1922. In 1929 the form became a Proprietary Limited Company with an additional two stores, at 95 Elizabeth and 361 Swanston Streets, Melbourne. Collins Booksellers is still owned by the Stamen family. It is the largest Australian-owned bookselling chain.The book is significant due to its connection with navigation at sea. Its author W M Smart was a learned astronomer and an Instructor-Lieutenant for the Royal Navy during World War I. His achievements were recognised in 1958 when he was awarded the Lorimer Medal of the Astronomical Society of Edinburgh.A Handbook of Sea Navigation: The Theory & Practice of Astronomical Navigation at Sea, with diagrams and charts Author: W M Smart, M.A., D.SC., F.R.A.S.

This technical textbook is the nineteenth edition of the book by Henry Raper, Lieutenant in the Royal Navy with awards that include F.R.A.S. (Fellow of the Royal Astronomical Society) and F.R.G.S. (Friend of the Royal Geographical Society). The book is dedicated in honour of Rear-Admiral Sir Francis Beaufort K.C.B., Hydrographer to the Admiralty. He was awarded the title K.C.B. (King's Commander) as a Member of the Order of Bath, an order of British Chivalry, The book was first published in 1840 and soon became a resource for navigation students. It includes topics on nautical navigation, astronomy, navigation charts, calculations and mathematical tables, time, tides, ships, longitude, and position at sea. Thomas A. Hull, who revised and expanded this edition, was a Commander in the Royal Navy and had previously been Superintendent of Admiralty Charts used for navigation worldwide by seamen from many walks of life. The publisher, J D Potter of London, was at that time the sole agent for the Admiralty Charts produced by the Royal Navy. Printer Spottswoode and Co.,. was established by William Strachan in 1738. In 1819 his nephews A and R Spottswoode took over the business and bought premises in New-Street Square and Shoe Lane. In 1850 over 200 workers were employed by the firm. and five years later the business became Spottswoode & Co. Andrew Spottswoode invented the Spottswoode Press.This technical book was very popular as a textbook for students of maritime navigation, written and updated by members of the British Royal Navy and relied upon for accurate advice and information. The first edition was published in 1840, this edition was updated, expanded and published in 1891 when ports around the world were filling with travellers, merchants and business people.

This pair of navigational lamps or lights was fitted to the vessel S.S. Rowitta when it was renovated to become a display passenger ferry at Flagstaff Hill Maritime Village from 1976-2015. Navigation lamps are used to indicate a vessel’s position and direction of travel to other vessels nearby. This system of coloured lamps is standardised throughout the world for all marine vessels, red is for port and green for starboard, (red is for the boats right hand side). These navigation lamps were not the original fittings for this vessel but had come from a similar vessel of the same era of the early 1900’s. The history of the lamp fittings at this time is unknown. SS ROWITTA: - The 1909 steam ferry, SS Rowitta, was installed as an exhibit at Flagstaff Hill in 1975 and was enjoyed by many visitors for 40 years. Rowitta was a timber steam ferry built in Hobart in 1909 using planks of Huon and Karri wood. She was a favourite of sightseeing passengers along Tasmania’s Tamar and Derwent rivers for 30 years. Rowitta was also known as Tarkarri and Sorrento and had worked as a coastal trading vessel between Devonport and Melbourne, and Melbourne Queenscliff and Sorrento. In 1974 Rowitta was purchased by Flagstaff Hilt to convert into a representation of the Speculant, a historic and locally significant sailing ship listed on the Victorian Heritage Database. (The Speculant was built in Scotland in 1895 and traded timber between the United Kingdom and Russia. Warrnambool’s P J McGennan & Co. then bought the vessel to trade pine timber from New Zealand to Victorian ports and cargo to Melbourne. She was the largest ship registered with Warrnambool as her home port, playing a key role in the early 1900s in the Port of Warrnambool. In 1911, on her way to Melbourne, she was wrecked near Cape Otway. None of the nine crew lost their lives.) The promised funds for converting Rowitta into the Speculant were no longer available, so she was restored back to her original configuration. She represented the importance of coastal traders to transport, trade and communication in Australia times before rail and motor vehicles. Sadly, in 2015 the time had come to demolish the Rowitta due to her excessive deterioration and the high cost of on-going repairs. She had given over 100 years of service and pleasure to those who knew her. These lamps are an historical example of navigational equipment used in the early 20th century, adhering to a navigational standard that is worldwide, and a design similar to what is still being used today. They were used on the display vessel at Flagstaff Hill Maritime Village as an aid to maritime education. The Rowitta represents the importance of coastal traders to transport, trade and communication along the coast of Victoria, between states, and in Australia before rail and motor vehicles. The vessel was an example of a ferry built in the early 20th century that served many different roles over its lifetime of over 100 years. Two side navigation ship's lamps, quarter circle shaped metal boxes with glass window and removable lid. The lid attaches to the box using four brackets, wingnuts and screws that swing down out of the way. The window of double-thickness glass is inserted on the curved side of the box and attached by screws around the frame. The inner glass panel is coloured according to the lamp’s use; port is red and starboard green. The port lamp has a round hole cut into each of the two straight sides and an electrical fitting inside. The starboard lamp also has a hole in each straight side (one with a threaded fitting). Its lid has an additional cross bar on top that has a circular space in the centre, nuts and screws fit through holes in the ends and a folding handle is attached across the centre space. The lamps were once fitted onto the vessel Rowitta. The starboard lamp has an inscription stamped into the metal.

An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or “one-eighth of a circle,” for the Octant’s arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. History: The principle of the Octant as an instrument to measure ones latitude was first implemented around 1742-present but was superseded by the improvement of the octant to a sextant, a very similar instrument, better made and able to measure bigger angles 120°, allowing the measurement of Luna distances to give longitude when used with an accurate chronometer. The sextant started to appear around 1730 and had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a Sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. Henry Hemsley was a lesser-known instrument maker and optician working in London in the late 17th and early 18th century. However, it should be noted that there were two Henry Hemsley opticians and instrument makers around this period. (Henry Hemsley 1, 1786-89, who had premises at 85 Fleet St London and Henry Hemsley 2, 1828-56), whose workshop was at 135-138 Radcliff Highway London. Therefore, based on the inscribed workshop address Henry Hemsley 2 is responsible for making this example.The octant is representative of its type and although not fully complete it demonstrates how 18th and 19th-century mariners determined their latitude on a chart to navigate their way across the world's oceans in the 18th and 19th century. It also demonstrates the skill and workmanship of the early instrument makers that operated from London at this time and provided most of the navigational instrumentation use by commercial and military navies of the time.Octant, ebony wooden frame and handle.

A Fresnel lens is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use primarily in lighthouses.  Made from high-quality glass Fresnel lenses were used originally in lighthouses and later for many other applications They were later being used for automobile headlamps, brake, parking, and turn signal lenses, and many other applications. Fresnel lenses used in lighthouses were considered state of the art from the late 19th through to the middle of the 20th century. The subject item is a Fresnel replacement lens used in a ships navigation light. For lighthouses, these lenses have now been replaced with much less expensive and more durable aerobeacons, which themselves often contain plastic Fresnel lenses. The lens design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The catadioptric form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source making the light visible from greater distances.The subject item at this time cannot be associated with a historical event, person or place, provenance is unknown, the item is a replacement for a ships navigation light and it is believed to have been produced before 1950.Fresnel glass replacement lens for a navigation lamp of a ship.

The personal 'carry-all', a cloth apron like article was utilised by Thomas Hamilton Osborne in his work with the Warrnambool Steamship Navigation Company. He was Company manager in 1883 until its dissolution in 1899. Osborne wrote many articles on early Warrnambool, particularly maritime material under the name of " Sliding Gunter". When he died he was buried at sea off the breakwater.His sister Mrs Annabella Kell is thought to have made this article.This is a significant item as T.H.Osborne was a key figure in 19th Century Warrnambool history, particularly in maritime affairs.

This plate was made by the Calyx Porcelain and Paint Company which was based in Western Australia and made china for commercial establishments from the 1920s to the 1990s when the company was then known as Australian Fine China. The plate was used by the Belfast and Koroit Steam Navigation Company based in Port Fairy. It was founded in 1882 and operated two ships, the Casino and the Bellinger, servicing the Western Ports between Melbourne and Portland. The Casino was wrecked at Apollo Bay in 1932. Later the company operated the ship, Dawn and survived as a shipping company until the late 1930s.This plate is of interest because it was used by the Belfast and Koroit Steam Navigation Company in the 1920s and 30s.

The photograph shows the three-masted iron and steel bark "Newfield" sailing in open seas. It event would have been between 1889-1892 during the ship's working life. ABOUT THE NEWFIELD The Newfield was a three-masted iron and steel barque, built in Dundee, Scotland, in 1889 by Alexander Stephen and Sons. It was owned by the Newfield Ship Company in 1890 and later that year It was registered in Liverpool to owners Brownells and Co. The Newfield left Sharpness, Scotland, on 28th May 1892 with a crew of 25 under the command of Captain George Scott and on 1st June left Liverpool. She was bound for Brisbane, Australia, with a cargo of 1850 tons of fine rock salt, the main export product of Sharpness. At about 9pm on 28th August 1892, in heavy weather, Captain Scott sighted, between heavy squalls, the Cape Otway light on the mainland of Victoria but, due to a navigational error (the ship’s chronometers were wrong), he assumed it to be the Cape Wickham light on King Island, some 40 miles south. He altered his course to the north, expecting to enter Bass Strait. The ship was now heading straight for the south west Victorian coast and at about 1:30am ran aground on a reef about 100 yards from shore and one mile east of Curdie’s Inlet, Peterborough. The ship struck heavily three times before grounding on an inner shoal with 6 feet of water in the holds. Rough sea made the job of launching lifeboats very difficult. The first two lifeboats launched by the crew were smashed against the side of the ship and some men were crushed or swept away. The third lifeboat brought eight men to shore. It capsized when the crew tried to return it to the ship for further rescue The Port Campbell rocket crew arrived and fired four rocket lines, none of which connected with the ship. A local man, Peter Carmody, volunteered to swim one mile to the ship with a line to guide the fourth and final lifeboat safely to shore. Seventeen men survived the shipwreck but the captain and eight of his crew perished. One of the men, apprentice William McLeod, was rescued by local woman Margaret E. MacKenzie. The Newfield remained upright on the reef with sails set for a considerable time as the wind slowly ripped the canvas to shreds and the sea battered the hull to pieces. The Marine Board inquiry found the wreck was caused by a "one man style of navigation" and that the Captain had not heeded the advice of his crew. According to Jack Loney ‘… when the drama was over . . the Newfield was deserted except for the Captain’s dog and two pigs.’ Flagstaff Hill Maritime Museum has several artefacts that have been salvaged from the wreck. The report from SHP documented the following in regards to the Newfield collection: Flagstaff Hill’s collection of artefacts from the Newfield is of historical and archaeological significance at a State level, because of its association with the shipwreck, which is on the Victorian Heritage Register. The collection is significant because of its relationship between the objects. The Newfield collection is archaeologically significant as it is the remains of an international cargo ship. The Newfield collection is historically significant for representing aspects of Victoria’s shipping history and its potential to interpret sub-theme 1.5 (Living with natural processes). The collection is also historically significant for its association with the shipwreck. Black and white photograph of the three-masted sailing ship “Newfield” in the open sea, sails unfurled.

Dividers are used by navigators to measure the distance between two points on a map or chart. Each point of the divider is places on a map point, then the distance between the points of the divider is measured against the scale of the chart or map. This helps determine the ship's path of travel, the distance travelled and the current location.Not very significant as not associated with any historical event or person, same pattern of dividers is available today from many retail outlets. Also item was probably made around 1940s to 1950sDividers; brass navigator's dividers with fine, stainless steel points. Made in Britain by W & H C (inscription). This navigational tool is used by a ship's navigator to mark the ship's position.

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.

250 pages, Appendices, Bibliography and Indices, extensively illustratednon-fictionThis high-quality book is the extraordinary story of an ordinary little ship that had a long and eventful life. Perhaps few Australian coasters have had a more interesting and varied history. Built in Scotland in 1912 for the North Coast Steam Navigation Company, Tambar worked as a lifeline to isolated river and island communities, first in New South Wales, then for the Tasmanian Government and Holymans in Bass Strait (King Island) and as the last steamer serving the Gippsland Lakes. In between she even spent a few years in Papua New Guinea. When World War II broke out, Tambar was commissioned into the RAN as an auxiliary minesweeper, but after the terrible Darwin air raid in 1942 became the first vessel of the newly formed Salvage Board, later assisting in the search for survivors of the Battle of the Coral Sea. Returning to Bass Strait in 1944 for a few more years, she then spent the 1950s on standby as a salvage vessel in Melbourne, working on Merilyn, Terawhiti, E.J. Fairnie, and River Burnett. Craig Mair grew up in Grangemouth, Scotland where Tambar was built, and became interested after inheriting a builder's model from his father. He has consulted thousands of records, including the ship's logs, tracked down witnesses, and assembled over 100 photographs and maps to give a unique insight into Tambar's story, and coastal Australia in the middle decades of the twentieth century, before roads took over the transport task. Besides many colourful stories of shipwrecks and strandings, strange cargoes, salty characters, exotic places, wartime air raids, and salvage jobs, the book includes a definitive account of the worst Second World War 'friendly fire' incident in Australian waters in Moreton Bay in 1942.naa, australian national line, interest group, moreton bay, tambar, coaster, ships

This ship was number 1 of 2 ships named Bangalore and run by P & O. This ship has listed the same tonnage as that on the inscription on the frame of this work. The ship was subsequently sold in 1886 sold to Hajee Cassum Joosub and used for passengers on pilgrimage into Jeddah. Another view of the history of the Bangalore is that to be found at the Maritime Museums of Sydney listing of another painting of the Bangalore which provides a somewhat different history. It is possible that the story of Bangalore 1 and Bangalore 2 have become conflated further research is needed to verify. see Links field. SS BANGALORE was built in 1867 by William Denny of Dumbarton. Owned by P&O, SS BANGALORE operated from Bombay and Galle to Melbourne and Sydney from 1872 to 1886 as a passenger and mail ship. In 1891 BANGALORE was sold to Wilh.
