James Bryance CONDER (aka James Brycanne CONDER) Artist, poet and four-navy veteran, 1872 - 1954. In 1889 he served in the Merchant Marine Service sailing on the ships ‘Ellora’ and ‘Avenger’. in 1891, aged 19, he joined the Royal Navy in Australia serving on the flagship of the Australian Station, ‘HMS Orlando’, when it escorted ships of the new Australasian Auxiliary Squadron in coastal voyages. After serving 6 months he returned to family in Melbourne rather than sign on for 12 years. Instead he joined the Victorian Colonial Navy and was posted, in succession, to the ‘HMVS Cerberus’, ‘HMVS Nelson’ and the gunboat ‘HMVS Albert’. In 1896 he left the navy, married Victoria Agnes NIHILL and joined the Victorian Police Force. In 1904 CONDOR returned to the sea as part of the Commonwealth Naval Forces, an amalgamation of the colonial navies formed after federation and later becoming the Royal Australian Navy. On his first ship, ‘HMS Katoomba’, as bosun yeoman, he helped train new recruits. He later served on ‘HMS Challenger’ and ‘HMS Psyche’ which included voyages to Fiji, the New Hebrides, Singapore and New Zealand as well as regular cruises to Australian ports. In 1909, CONDER left the Navy and undertook shored-based civilian work until 1913 when he joined the Royal Australian Naval College at Osborne House in Geelong. He remained with the Naval College until 1937 through its moves to Jervis Bay, NSW and then to Crib Point, Victoria training midshipmen according to the practices of the Royal Navy. In later life, CONDER produced two handwritten journals for his family illustrated with his own paintings and drawings. Two original sets were made. One remains in the family while the other is held by the Australian National Maritime Museum in Sydney. PMHPS hold several items relating to James CONDER including photocopies of his journals ‘Notes from a Sailors Log - Under Canvas - Part I The Merchant Service’ (Cat No 2700.01) and ‘Notes from a Sailors Log - Under Steam - Part II The Navy’ (Cat No 2700.02), a photocopy of his Certificate of Service (Cat No 2700.03), a booklet of his life story (Cat No 2700.04) and several digital items (Cat No 2476.01 - 2476.09).Article, 'One Man's Four Navies', about James CONDER from National Maritime Museum's 'Signals' magazine, Issue 12, 1 June 1990. armed services - navy, transport - shipping, james bryance conder, ran - royal australian navy, royal naval squadron, victorian colonial navy

A flare, also sometimes called a fusee, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signalling, illumination, communication or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or hand held percussive tubes. Signalling flares have been in use by all branches of the military services since the 1920s also by the maritime services to signal other ships or for distress purposes. The earliest recorded use of gunpowder for signalling purposes was the 'signal bomb' used by the Chinese Song Dynasty as the Mongol-led Yuan Dynasty besieged Yangzhou in 1276. These soft-shelled bombs, timed to explode in mid-air, were used to send messages to a detachment of troops far in the distance. Another mention of the signal bomb appears in a text dating from 1293 requesting their collection from those still stored in Zhejiang. A signal gun appears in Korea by 1600. The (Wu I Thu Phu Thung Chih or Illustrated Military Encyclopedia) written in 1791 depicts a signal gun in an illustration. The item was used to carry and store flares for signalling use as the inscription on the canvas cover suggests. Given the method of storing flares is in a wicker basket that is non conducting of an electrical charge that may accidentally set of explosive materials. The writer assumes the basket was used from the early 20th century and most likely by maritime or military services to store it's flares.Basket cane square with metal locks & rope handles each end.

This ship's pully sheave was part of the Antares rigging. A pulley sheave is a circle on a shaft that is manufactured to hold up movement and change of way of a cable or/and rope, or transfer of power between the shaft and cable or/and rope. A pulley is a unique mechanism that is used to leverage the lifting of heavy loads to required heights. The Italian barque Antares was an iron three-masted sailing clipper built in 1888 by Russell & Co of Port Glasgow originally named the “Sutlej” and renamed in 1907 the “Antares” when sold to the Semider Bros of Genoa Italy. The vessel left Marseilles on the 18th of December 1913 with its master captain Gazedo destined for Mullaly & Byrne of Melbourne with a cargo of roofing tiles but failed to arrive. The wreckage was found near the Bay of Islands twenty-two miles east of Warrnambool after a body had washed ashore. Some of the timbers washed up were charred by fire, and a small boat's stern board with the name "Sutlej" led to the identification of the wreck as Antares which had been reported missing. According to later reports, the Antares wrecking was overshadowed by war news at the time. A young local boy had remarked that the Germans had arrived off the coast as he had seen them firing off shells and rockets, but his story was passed off as a joke. These rockets were most likely the distress signals from the stricken ship. The Italian barque/clipper Antares was sometime later reported as overdue. The wreck of the ship was later found at the base of a cliff at the Bay of Islands near Warrnambool in November 1914, there were no survivors.The Antares is significant as it was a sail trader carrying an international inbound cargo during the early part of the 20th century. It is part of the Great Ocean Road Historic Shipwreck Trail and as such is registered as a protected wreck in the Victorian Heritage Database VHS S34.Pulley sheave; brass, with recesses full of concretion.

The Sea-Cell pamphlet was written by Captain Henry Moors of the Land Forces Signal & Torpedo Corps. In the pamphlet Captain Moors investigates the theory that the zinc case of the torpedo, the iron hull of Cerberus and the sea water combined to form a sea-cell. (battery) Captain Moors investigates whether this sea-cell could have resulted in a current being produced that was strong enough to detonate the torpedo.Eleven page pamphlet measuring 137 mm x 215 mm exploring the possibility that the Cerberus torpedo accident was caused by a Sea-Cell effect.sea-cell torpedo

The Ship Owners proposed a Union Jack with a six inch red border on all sides. They thought this would be cheaper than introducing a new flag, as every ship already had a Union Jack. They also suggested that in the proposed Regulations relating to Pilotage the same flag should be specified as the signal for a pilot. Their Lordships agreed to this, but the border was to be white instead of red, and the size of the border was to be a proportion of the size of the flag. The new flag was warranted on 8 July 1823, the details published in the London Gazette on the 9th, to be effective 1 January 1824. The establishment of the Union Jack on a white boarder as a request for pilot flag in British port took effect from 1824.Flag flown by UK registered merchant vessels requiring pilotage on approach to UK portspilot flag, union jack, flags

Flashlights where a vital tool for night time map reading, signaling with coloured lenses and many other uses. The blackout during the war also meant for a extended popularity of flashlights. Many carried them onto the streets to see as the streetlights where very rare and to top that of mostly blacked out. Most flashlights where fitted with blinds or coloured lenses to hide the bright light they produced. These coloured lenses where also used to signal between individual soldiers. Mostly used in the 1940s by the military and civilians alike. A small metal light signal box or flashlight.Petrix No. 678signal box, flashlight, petrix 678

The ship's log part, called a fish, is likely to be from a mechanical taffrail log system. It was recovered from the wreck site of the barque, the 1840-1852 Grange. There are no marks on the fish to identify its maker or model. It is part of the John Chance Collection. This ‘fish’ is part of an early to mid-1800s ship's log. It would likely have been part of a taffrail log connected to a rotor (also called propeller, spinner) by a strong line, and the other end connected by a line to a dial mounted on the taffrail, or stern rail, at the stern of the vessel. As the propeller rotated through the water it would spin the log, which in turn would cause a number to register on the dial, showing the current speed in knots; one knot equals one nautical mile per hour. TAFFRAIL LOGS A taffrail log is a nautical instrument used for measuring the speed of a vessel, providing vital navigational information to be calculated, such as location and direction. A log has been used to measure the speed of a vessel since the 1500s. A simple piece of wood was tied to a long line and thrown into sea at the back of the vessel. The rope was knotted all along at equal distances apart. On a given signal the log line was pulled back into the vessels, the knots counted until the log came up, then the figures were calculated by a navigator In 1802 the first successful mechanical log available for general use was invented by Edward Massey. It had a rotor 'V' section connected to a recording mechanism. The water’s movement rotated the rotor, which intern sent the movement to the recorder. There are examples of this invention available to see in some of the maritime museums. Thomas Walker, nephew of Edward Massey, improved on Massey’s design, and Walker and his son took out a patent on the A1 Harpoon Log. In 1861. Both Massey and Walker continued to improve the designs of the taffrail log. New designs were still being introduced, even up to the 1950s. THE GRANGE, 1840-1858- The wooden barque ’Grange’ was a three-masted ship built in Scotland in 1840 for international and coastal trade. On March 22, 1858, the Grange set sail from Melbourne under Captain A. Alexander, carrying a cargo of ballast. The barque had left the Heads of Phillip Bay and was heading west along the Victorian coast towards Cape Otway. The ship struck Little Haley’s Reef at Apollo Bay due to a navigational error and was stuck on the rocks. The crew left the ship carrying whatever they could onto the beach. Eventually, the remains of the hull, sails and fittings were salvaged before the wreck of the Grange broke up about a month later. About 110 years later, in 1968, the wreck of the Grange was found by divers from the Underwater Explorers Club of Victoria. They were amazed to find a unique, six to nine pound carronade (type of small cannon) and a cannonball on the site. There have been no other similar carronades recorded. In that same year the anchor of the Grange was recovered by diver John Chance and Mal Brown. The ship’s log is significant historically as an example of hardware used when building wooden ships in the early to mid-19th century. The ship’s log is historically significant as an example of the work and trade of blacksmith. The ship’s log also has significant as it was recovered by John Chance, a diver from the wreck of the Grange in the 1968. Items that come from several wrecks along Victoria's coast have since been donated to the Flagstaff Hill Maritime Village’s museum collection by his family, illustrating this item’s level of historical value. The ship’s log is historically significant for its association with the 1840s wooden barque, the Grange. The Grange is an historical example of a Scottish built vessel used for international and coastal trader of both cargo and passengers in the mid-19th century. The Grange is an example of an early ship, designed with a wooden hull. It is significant as a ship still available to divers along the south coast of Victoria, for research and education purposes. The Grange is an example of a mid-19th century vessel that carried a weapon of defence onboard. Ship log fitting, called a fish; part of a brass navigational instrument, likely to be from a taffrail log. The metal is a tan colour and has rough surface with a sheen, and discolouration in places. Its basic shape is a hollow cylinder with ends tapering to a smaller size. In the centre there are opposing openings cut out, showing a rough texture inside. One end on the cylinder is closed with a ring and shank installed, fixed by an embedded screw through the end of the cylinder.

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.

This three-dimensional Distant Signal is part of a Flagstaff Signal set of ball, cone and drum shapes. It has been woven and then fabricated with strong metal swivel fittings and loops for suspending from a high point on a flagstaff at a signal station or on a ship’s masthead. The cane signal was constructed to withstand all weather and to be visible from a long distance. The gaps between the woven cane allow air to pass through, minimising possible swaying. Similar sets were made from rope or fabric. Warrnambool's Flagstaff was erected in 1854. Its primary use was to display visual signals that could convey messages between land and sea. It was also used to notify the local population of the approach of ships. One of the popular signalling codes in use in the early-to-mid 1800s was the Marryat’s Code but there were others in use as well; there was no one standard code. In 1857 the International Marine Conference adopted an International Code of Signals as a standard communications system for all vessels that could be understood in many different languages. The Normanby Advertiser reported on June 5th 1857 a query from the Post Master General as to whether the request of the Chief Harbour Master would be carried out, in that Warrnambool would receive a new flagstaff and a set of Marryatt’s signal flags. The Table of Codes was published, showing how to use combinations of these flags to send messages. The Code was revised in 1887 to cover situations where distance, light, wind and weather conditions affected the visibility of the flags and prevented clear communication. The first report of the International Code of Signals Committee of 1897 warned signalmen not to rely on ordinary semaphore flags and introduced a Distant Signal Code using either particular semaphore flags or the three-dimensional shapes of a ball, cone and drum that aligned with the semaphore flag shapes of a circle, pennant and square. International Code of Signals In 1931, after World War I’s experiences in using signal codes, the International Code of Signals conference in Washington revised and published the rules for the conduct of signalling. One of the changes was that “the use of the Distant Signals and of fixed semaphore was abandoned”. It is of interest to know that modern marine law in many countries insists that a set of Day Shapes must be carried onboard vessels of a certain size. These highly visible geometric shapes are used at sea in daylight to communicate messages between vessels. They are used in a similar way to the Distant Signals, in that different combinations of shapes represent different messages. The set of shapes includes a ball, cylinder, cone and diamond. The shapes are hung between the top of the vessel’s foremast and the front of the vessel. They are only coloured black and are about 1.5 metres high. The vertical line of shapes can mean messages such as Boat not under command, Fishing, and Under sail and power.Distant Signals were an important means of marine communication from the late 1880s to the early 1930s, including during World War I. They were an advancement to the International Shipping Codes and safety. The cane signals’ shapes appear to be the same from whatever direction they are viewed, removing confusion about the message they convey. The same shapes continue to be used today for the sets of Day Shapes used as marine navigational signals that are mandatory on certain-sized vessels.Distant Signal Cone, part of a Flagstaff signal set.
