Document - Navigation Chart, Admiralty Office, Lady Bay and Warrnambool Harbour, 1893
... Navigation Chart...Navigation chart...Navigation Chart: Lady Bay and Warrnambool Harbour... shipwreck coast Map chart Navigation chart plan Lady Bay Warrnambool ...This navigation cart of Lady Bay and Warrnambool Harbour was originally surveyed in 1870 but this version includes the update for magnetic variation in 1893. Since the printing of the chart several annotations have been added. These include an additional stamp dated 15-8-1910, a handwritten comment across the top of the page dated August 1910, and another handwritten comment regarding the ‘Proposed Extension of Dock’ dated 19-2-1925, plus connected drawings, notes and figures. The 1925 proposal on this chart may have been a reaction to the Royal Commission of 1923, when the damaged stonework on the seaward side of the Warrnambool Breakwater, caused by the action of the sea, was the subject of enquiry. A conference between the Public Works, Water Commission and the Harbour Trust concluded that it would less costly to make repairs to prevent further damage rather than replaced the damage portion of the wall. A contract was raised in late 1924 to deposit rubble on the damaged side of the breakwater to minimise the Southern Ocean’s destructive action and work had started by August 1925. The Breakwater construction had begun in 1874 and was completed in 1890. The Victorian Government had commissioned Sir John Coode, a British harbour engineer, to present a plan to complete the Warrnambool Breakwater but his original plan was too expensive. He prepared a revised plan for a shorter structure. The construction proved to be too short to protect adequately from the weather and didn't allow enough depth for larger vessels to come into port. The decreasing trade was further affected by siltation in the bay due to the breakwater, and the completion of the railway line. The situation of the harbour became a real problem by 1910 and required continuous dredging. In 1914 the Breakwater was extended but proved to be a failure because the work began to subside and by 1920 about two thirds of the harbour was silted up. Alterations made in the 1920's increased the silting problem and by the 1940's the harbour was no longer used. More alterations were made in the 1950's and 1960's. This chart is significant for its strong connection to the maritime history of Warrnambool Harbour and Lady Bay and the Warrnambool Breakwater. The Warrnambool Breakwater is registered as a place of significance on the Victorian Heritage Database (VHR H2024). The Warrnambool Breakwater is one of the most important late 19th century maritime engineering projects in Victoria and significant in the development of Victorian coastal shipping. It is also significant for its connection with British harbour engineer, Sir John Coode. The chart is a historical record of structures existing in 1893; the Warrnambool Jetties, Warrnambool Breakwater in Lady Bay, the leading lights (lighthouses), streets, roads, bridges and many buildings. It also shows the lay of the land and seabed. Navigation Chart: Lady Bay and Warrnambool Harbour, Australia - South Coast - Victoria. Surveyed by Nav. Lieut. H.J. Stanley, R.N., 1870.

... Navigation Chart...Navigation chart... Maritime Village shipwreck coast Map chart Navigation chart ...This Chart titled “Lady Bay and Warrnambool Harbour” was surveyed by Nav. Lieut. H.J. Stanley, of Britain's Royal Navy, in 1870 and printed in April 1871. The chart was made before the Warrnambool Breakwater was built (construction had begun in 1874 and was completed in 1890). The chart includes Directions for entering Lady Bay, Warrnambool Harbour. These are "Vessels entering Warrnambool Harbour must bring the Red Light in sight and steer in with it in line with the upper white Light bearing North, until the Green Light on the Jetty is opened, when steer towards it and anchor. The best anchorage is in 2 ¼ fms [fathoms)] of water, about a cable from ledge off Breakwater rock. Or where convenient, according to draught of water, only endeavouring to anchor as close as possible to Breakwater rock. It is not safe to enter or leave the Harbour in south westerly or Southerly gales.” This chart is significant for its strong connection to the maritime history of Warrnambool Harbour and Lady Bay, and eventually to the Warrnambool Breakwater. The Warrnambool Breakwater is registered as a place of significance on the Victorian Heritage Database (VHR H2024). A copy of the same chart was used to plan several submissions for future changes to the jetty and breakwater. The chart is a historical record of structures existing in 1870; the Warrnambool Jetties, Lady Bay, the leading lights (lighthouses), streets, roads, bridges and many buildings. It also shows the lay of the land and seabed.Canvas chart of Australia, South Coast, Victoria Title: Lady Bay and Warrnambool Harbour Surveyed by Nav. Lieut. H.J. Stanley, R.N., 1870.

Top half is alloy plated ...Compass, divider, and caliper are basically instruments that have two legs pivoted to each other at the top and are concerned with small-distance measurement or transfer. The compass and divider have straight legs; the caliper has curved legs. Dividers and Calipers were known to both the Greeks and Romans, though the caliper was uncommon. A divider with a circular sector, or wing, connecting the two legs was sketched in 1245, its modern counterpart is the wing divider with a thumbscrew clamp and screw for fine adjustment. Or the marine dividers used to measure the distance a vessel has travelled by transferring the vessels distance from a map with the divider and transferring that measurement to a marine ruler to mathematical calculate the distance.Item is believed to be a replica/ copy of a 19th century map calipers used in marine navigation to determine distance travelled.

(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.

Instrument - Hourglass
... ship’s log, plot them on his navigational chart and give his... ship’s log, plot them on his navigational chart and give his ...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.

An aeronautical chart is a map designed to assist in navigation of aircraft. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. World aeronautical charts have a scale of 1:1,000,000 and cover relatively large areas. Orbost Aero Club began in 1969 with Basil Dowie as Chair, David Nixon as Secretary/Treasurer. The group went into recess from 1977-1991 closing in 1997. The mid 1960s were boom years in flying training in Australia and the number of Aero Clubs grew rapidly. The Club played a significant role in the establishment of the small airport at Marlo and in the ongoing operation and development of the airport over the years particularly for patient transfer by aerial ambulance.

Photograph - Historical, Warrnambool, C. 1854-1871
This is an image of the Warrnambool Lighthouse Complex on Middle Island in 1854. The Store, Lighthouse Keeper's Quarters, Lighthouse and Flagstaff are in the background. The foreground shows a covered buggy drawn by two horses and a person in attendance, and another wheeled vehicle behind it with a figure nearby. There is a saddled horse to the right with two males in conversation nearby. The ground is soft, perhaps the riverbed or sandy shore. THE LIGHTHOUSE KEEPERS Lighthouse Keepers were responsible for keeping their Lighthouse’s lights shining at night. They kept a lookout for passing vessels and changes in weather. They were expected to clean, polish and maintain the equipment and buildings. They kept regular and detailed records of who was on watch, and the time the light was lit, trimmed and extinguished. They kept a journal about other events that occurred. They keep regular, accurate Meteorological Logs. It was expected that they were competent in Morse code signalling. They would be called to help in times of disasters and shipwrecks and to give official statements about these events. Many Lighthouse Keepers also volunteered as members of the lifeboat crew. The Lady Bay lighthouses were officially classified as small, so the Keepers had the official titles of Senior Assistant Lighthouse Keeper and Assistant Lighthouse Keeper. They were employed by the Public Service and paid rent to live in the Lighthouse Quarters. They were compulsorily retired at the age of 60, with most receiving a superannuation payment. Despite their time-consuming duties, there was time to follow hobbies and crafts such as growing vegetables, playing musical instruments, making models of buildings including lighthouses, and crafting furniture pieces. An example of a keeper’s skills is the carved fire screen made by /assistant Keeper Thomas Hope in the late 19th century and displayed in the Lighthouse Keeper’s cottage at Flagstaff Hill. Both Alexander and Farncombe had served under Senior Keeper Robert Deverell, who was the first and only Senior Lighthouse Keeper at the Middle Island Complex. John Alexander was the Assistant Keeper in the 1850s. Andrew Farncombe was the last Assistant Keeper at Middle Island, serving there with his family from 1864 to 1871. During 1871 and 1872 the Lighthouse Complex was moved to Flagstaff Hill on Merri Street. Farncombe and Deverell then became the first Keepers and occupants of the Lady Bay Lighthouse Complex at Flagstaff Hill. They continued their service together; overall, Deverell served from 1859 to 1885 and Farncombe from 1864 to 1974. WARRNAMBOOL'S LADY BAY LIGHTHOUSE COMPLEX - The original Lighthouse Complex was built on Middle Island in 1858-1859 then transferred stone-by-stone to Flagstaff Hill in 1871. The Complex comprised the Lighthouse, the Lighthouse Keepers’ Quarters and a Privy. The bluestone Keeper’s Quarters was a cottage divided into two compartments, one for the Senior Keeper and his family, the other for the Assistant Keeper and his family. The bluestone Store was divided into three; a store, a workshop, and an oil store (or office). The Privy comprised a small building also divided into two separate, back-to-back toilets, one for each Keeper and his family. In the 1970s the Flagstaff Hill Planning Board was set up under the chairmanship of John Lindsay. The Board was to make recommendations to the Warrnambool City Council regarding the use of the buildings and the rest of the Crown Land on the site. The Flagstaff Hill Maritime Village opened in 1975 and began renovating the Cottage in stages, during which time evidence of a 1920s fire was found in the eastern section of the cottage. Additions of a porch on the west and a washroom on the east were made in the 1980s. The western part of the building is now a Shipwreck Museum and the east has returned to a late 19th-century Lighthouse Keeper’s cottage and includes the screen made by Assistant Lighthouse Keeper Thomas Hope in the late 19th century. Hope served two periods of time at the Lighthouse. This photograph is significant as a visual record of the original Warrnambool Lighthouse Complex on Middle Island, the origin of what is now the Lady Bay Lighthouse Complex. The photograph is significant for its connection to the Complex, which is now listed on the Victorian Heritage Register, H1520, for being of historical, scientific (technological) and architectural significance to the State of Victoria. The Complex is significant as an example of early colonial development. The photograph is significant for its connection with the important navigational function of the Lighthouses, a function still being performed to this day. The photograph is also significant as it shows an example of buildings organised by the Public Works Department in Victoria in the mid-to-late 19th century. The structures tare still stand strong.

Instrument - Octant, mid 1800's
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.

Instrument - Navigational Sextant, 1882-1890
A sextant is an astronomical instrument used to determine latitude and longitude at sea by measuring angular distances, especially the altitudes of the sun, moon, and stars. It is a doubly reflecting navigation instrument and used mainly by sailors to measure the angular distance between two visible objects. The name comes from the Latin sextans, or “sixth part of a unit,” because the sextant’s arc can be 60° or 120° of a circle depending on the model used. The primary use was 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. This angle and the time when it was measured is used in order to determine Greenwich Mean Time and hence longitude. Sighting the height of a landmark on land can also give a measure of distance from that object. History: The development of the sextant was as an improvement over the octant, an instrument designed to measure one's latitude. The octant was first implemented around 1731-present but can only measure angles up to 45°. As larger angles were needed to allow the measurement of lunar objects - moon, stars and the sun - at higher angles, the octant was superseded by the sextant. The sextant is a similar instrument but better made and allows larger angles from 60° to 120°. This improvement allows distances to be accurately calculated thereby giving longitude when used with a chronometer. The sextant was derived from the octant in 1757, eventually making all previous instruments used for navigational positioning obsolete. The sextant 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. It should be noted that the octant and quadrant are in the same family as they were, and all are, regarded as sextants. The sextant is representative of it's type and although not fully complete it demonstrates how 18th,19th and 20th century mariners determined their latitude and longitudinal to determine their position on a chart, allowing them to navigate there way across the world's oceans. It also demonstrates the skill and workmanship of the early instrument makers that operated scientific instrument businesses from London and other areas of England to provide most of the navigational instrumentation used by commercial and military navies of the time.Sextant with square, fitted box of polished wood, "Hezzanith" brand.

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).

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.
