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. Each end point of the divider is placed on a position on a chart or map, then the length between the points of the divider is measured on the chart's scale.Inscribed "British Made" and "W & H C". flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, navigational dividers, navigational tool, dividers made by w & hc, w & hc britain

The black and white photograph depicts the Lady Bay Lighthouse Complex at Flagstaff Hill, Warrnambool. It was opened on this site in 1871. From left to right, the Chartroom (previously named the Store), Upper Lighthouse, Flagstaff, Lighthouse Keeper's Quarters. The bluestone buildings are facing North on Merri Street. The Harbour Pilot's Lodgings were on the east of the Complex. There are two unknown male figures standing in front of the light-coloured picket fence that encompasses the Complex. The photograph is mounted on card. WARRNAMBOOL'S LADY BAY LIGHTHOUSES In the 1800s ships sailing from England to Australia began to use Bass Strait as a faster route to Melbourne. Small navigation errors led to many tragic shipwrecks. From 1848 lighthouses were operating along Victoria’s southern coast as a guide for sailors. Coastal towns such as Warrnambool grew and the exchange of trade and passengers was of great benefit. However, the uncertain weather changes, relatively shallow waters and treacherous, hidden rocky reefs were not really suitable for a Harbour and in the 1840s and 1850s, there were many shipwrecks in the area, with some even stranded in its Lady Bay harbour. A jetty was built in 1850 and a flagstaff to guide seafarers was placed up high on what became known now as Flagstaff Hill. In November 1857 the Victorian Government recommended that Warrnambool Harbour had beacons and two lighthouses to guide vessels into and out of the Harbour safely. The white light of the Middle Island lighthouse was to be used for the first time on September 1, 1859. The red light of the Beach Lighthouse, a wooden obelisk structure, was first operated on March 25, 1860, but in 1868 this light was ‘discontinued’ due to it being too low. Melbourne’s Department of Public Works decided to relocate the Middle Island Lighthouse Complex - Lighthouse, Keeper’s Quarters, Privy, Store Room and even water tanks - to Flagstaff Hill. The lower obelisk was shortened, and a protruding gallery, railing, and external ladder were added, and the light from the Beach Lighthouse. A green guiding light was erected on the end of the jetty. The transfer of the Complex began in March 1871. Each shaped stone of the lighthouse was carefully numbered, removed then reassembled on Flagstaff Hill. In 1872 the well was sunk behind the Lighthouse Keeper’s Cottage. The Keepers and families had left Middle Island in April and moved to Flagstaff Hill in October 1871. Vessels entering Lady Bay align the Upper and Lower Lighthouse towers during the day and the lights at night. The Upper Lighthouse is a round tower, and the Lower Light is square. The Lighthouses were categorised as harbour lights rather than coastal lights, so they remain under the control of the Victorian Government’s Ports and Harbours section. The lights were originally powered by oil, then acetylene gas, later by electricity, and then converted to solar power in 1988. In 1993 the solar panel was replaced by a battery charger. A decision was made in 1936 to replace the lighthouses’ lights with unattended lights that no longer required Keepers and Assistants. At least 29 Keepers had attended to the lighthouse from its opening in 1859 to when the last official Lightkeepers left In April 1916. The Warrnambool Harbour Board rented out the Quarters from 1916 to 1936. The Board closed down but the rentals continued with other unknown landlords. 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 using 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. He served as Assistant Keeper in Warrnambool for two periods.The Warrnambool Lighthouse Complex 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 buildings are significant for their connection with the important navigational function of the Lighthouses, a function still being performed to this day. The buildings are also significant as an example of structures designed and works carried out by the Public Works Department in Victoria in the mid-to-late 19th century. The structures still stand strong. Photograph; Warrnambool Lighthouse Keeper's cottage, lighthouse, flagstaff and chartroom at Flagstaff Hill, and a light-coloured picket fence with gate.

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.

The forty-two navigational flags appear to be a complete set. Their purpose-built, grey painted wooden locker is divided into forty-two pigeonholes, each holding one of the rolled up flags. It is simply built and stands on short legs and was originally open-fronted, but has since been covered with a protective clear Perspex panel. The set of alphabetic and numeric visual signalling flags (including substitute and answering pennants) are made of wool in various colour combination designs, with canvas sewn to one end that is threaded with hemp rope. Some of the flags have metal clips attached to the rope. The flags were used for communicating messages to passing ships. Knowledge of visual signalling was mandatory for all lightkeepers and all stations maintained a set of flags. Although used for centuries, visual flag signalling formally developed in the nineteenth century and was published internationally as a system in 1857. By the early twentieth century it had developed into an effective means of conveying all kinds of short range visual messages. Most flags are in good condition and their first level significance is enhanced by their completeness and integrity as a set still housed in their original locker, and by the signal charts that remain in the museum collection which offer further insights into visual signalling.1 - 42.

The word Planisphere (Latin planisphaerium) was originally used in the second century by Claudius Ptolemy to describe the representation of a spherical Earth by a map drawn in the plane. This usage continued into the Renaissance: for example Gerardus Mercator described his 1569 world map as a Planisphere. The word describes the representation of the star-filled celestial sphere on the plane. The first star chart to have the name "Planisphere" was made in 1624 by Jacob Bartsch. Bartsch was the son-in-law of Johannes Kepler, discoverer of Kepler's laws of planetary motion. A significant item of celestial mapping used by marine navigators This particular item was made and used in the first quarter to half of the 20th centuryPlanisphere of northern hemisphere, with canvas bag. Planisphere consists of a circular star chart attached at its centre to an opaque circular overlay that has a clear elliptical window or hole so that only a portion of the sky map will be visible in the window or hole area at any given time. The chart and overlay are mounted so that they are free to rotate about a common pivot point at their centres. The star chart contains the brightest stars, constellations and (possibly) deep-sky objects visible from a particular latitude on Earth. The night sky that one sees from the Earth depends on whether the observer is in the northern or southern hemispheres and the latitude. A Planisphere window is designed for a particular latitude and will be accurate enough for a certain band either side of that. Planisphere makers will usually offer them in a number of versions for different latitudes. Planispheres only show the stars visible from the observer's latitude; stars below the horizon are not included. A complete twenty-four-hour time cycle is marked on the rim of the overlay. A full twelve months of calendar dates are marked on the rim of the starchart. The window is marked to show the direction of the eastern and western horizons. The disc and overlay are adjusted so that the observer's local time of day on the overlay corresponds to that day's date on the star chart disc. The portion of the star chart visible in the window then represents (with a distortion because it is a flat surface representing a spherical volume) the distribution of stars in the sky at that moment for the Planispheres designed location. Users hold the Planisphere above their head with the eastern and western horizons correctly aligned to match the chart to actual star positions. "Made in Germany for GEORGE PHILIP & SONS Ltd.
