Anemometer
This device was used to measure surface wind speed and direction. This anemometer was located on a concrete pad outside room 2.15 on a steel pole. The pole was considered unsafe and the anemometer was relocated to it's current position. When lowering the pole it fell over and was badly damaged. The Bureau of Meteorology donated it to the museum. It was then repaired and restored. The central pole on which it is mounted is galvanised iron pipe painted black. The anemometer, a portable device that manually measures wind speed, was a necessary instrument once common to all weather stations. The arms are attached to a vertical rod and as the wind blows, the cups rotate, making the rod spin. The stronger the wind blows, the faster the rod spins. The anemometer counts the number of rotations, or turns, which is used to calculate wind speed, surface wind and direction. They were designed to be durable to withstand the corrosive environment and strong winds expected at coastal sites such as those at Gabo Island. Anemometers existed in the nineteenth century and their design was improved by various experts including John Robinson in 1846, John Patterson in 1926, Brevoort and Joiner in 1935 and Derek Watson in 1991 who added wind direction measurement to its functions. This example was made for the Bureau of Meteorology by the Melbourne instrument company, Synchrotac, which became registered and incorporated on 26 July 1966. It is now displayed inside the building. A good example of its kind, the anemometer has first level contributory significance for its historic value and provenance to the lightstation.Anemometer and tripod stand.

Wind Speed Recorder, "Maximum Gust Register"
Used on Gabo Island to measure maximun gust over previous 3 hours or between weather observations. Information on the back of the device implies that it was battery powered and indicates that it was used in conjunction with a Synchrotac brand anemometer. Its particular function was to measure maximum wind speed over three hours between weather observations. Like the other weather recording instruments in the collection, it became redundant to the Bureau of Meteorology’s needs. It is a good example of its kind and has first level contributory significance for its historic value and provenance to the lightstation.Black metal box with grey metal front.

Sling Psychrometer
Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Temperature and relative humidity have major impacts on fuel dryness and therefore upon the availability of fuel for combustion. The amount of fine fuel available can increase rapidly from nearly zero when fuel moisture content is more than 16% after rain or a heavy morning dew, to many tonnes per hectare as fuel dries out later in the day and the moisture content drops below 9%. This explosive escalation in the amount of available fuel can happen over a few hours on hot and windy days. A sling psychrometer is a simple device for determining air temperature and relative humidity. It contains two thermometers, one of which is covered with a wick saturated with ambient temperature liquid water. These two thermometers are called dry bulb and wet bulb. When the sling psychrometer is spun rapidly in the air, the evaporation of the water from the wick causes the wet bulb thermometer to read lower than the dry bulb thermometer. After the psychrometer has been spun long enough for the thermometers to reach equilibrium temperatures, the unit is stopped, and the two thermometers are quickly read. A psychrometric scale on the side of the instrument is then used to convert the dry bulb temperature TDB and the wet bulb temperature TWB into humidity information. The wet bulb temperature is approximately equal to the adiabatic saturation temperature. The thermometers fold back into the plastic handle when not in use.

Balloon Theodolite 1943
Used to measure the rate of rise of helium balloons The telescope is mounted on two movable axes. One axis (vertical) rotates to change elevation, the other (horizontal) azimuth. There are vernier scales and in some cases micrometres that give precise readouts of the relative position of the telescope to each axis. The instrument is set up so that it is level and it is pointed towards true north with both scales reading 0 degrees exactly. A balloon is released in front of the theodolite. It is sighted at timed intervals (usually one minute apart) and the position of the theodolite's telescope (azimuth and elevation) is recorded. It can chart the direction and velocity of winds at various altitudes The rate of ascent of a balloon is mostly dependant on the balloon's drag and its "free lift" (the vertical pull of the balloon). There is some degree of control over these these factors, and as a result, it possible to know approximately how high our balloon will be at any given time after its release. Given a known height and an angular direction (read off the theodolite) to the balloon, a fix is made of the horizontal movement component of the balloon's travel as it moves through different altitudes. The horizontal movement is due to the winds blowing the balloon around at the altitudes that the balloon is traveling throughTheodolite used to measure the rate of rising helium balloons The rate of rise is used in atmospheric calculations such as upper winds and determining inversion layersforests commission victoria (fcv), bushfire, weather -

Instrument - Becquerel Phosphoroscope (incomplete), c1860-1880
The phosphoroscope was invented by Alexander Edmund Becquerel and used to measure the amount of time that a phosphorescent substance will glow after being irradiated by a brilliant source of light.The phosphoroscope consists of a round metal chamber with a pair of rotating discs inside, arranged so that no light can pass directly through the chamber. The discs have cut-out windows spaced equally at regular angular distances and are turned by the hand crank linked to a gear mechanism. The sample is placed in a specially designed holder into the small opening near the gearing, and it is exposed to the light source through the large rear condensing lens.Engraved on chamber: 'Phosphoroscope de E.

Functional object - Cloth Chart, A.E. Putnam Co. Iowa, U.S.A, c. 1896
... in Warrnambool Vintage Measuring Instrument for Cloth Putnam's Cloth ...This item was used to measure accurately the length of cloth on a bolt of material without unwinding it. It also measured lace, all types of textiles and spools of ribbon. It is surmised it would have been used in general stores or department stores in the late 19th and early 20th centuries. This item was discovered in the late 1980s behind an old safe at Swintons Stores in Timor Street in Warrnambool. The item appears to have been used extensively and would have been very useful during a stocktake. It may have been used in the Swinton Stores which were first established in Timor Street in 1865 with one section of the stores selling furnishings, furniture, clothing and clothing materials. The item was manufactured by A.E. Putnam of Iowa, U.S.A. There was a patent registered in 1896 and a later 'improved' model with a patent date of 1907. This item is of considerable interest because of its rarity and survival, its connection to Warrnambool General Stores in the past and its value as a research tool in local social and economic history. The possible connection to Swintons Stores is important as this business operated from 1865 to 2024 and was one of the longest-surviving family businesses in Australia. This is a rectangular-shaped wooden pole with one slightly flattened side and numbers marked on each side in patterns resembling brick walls. At the top of the pole are two wooden pieces attached to the pole by metal clips held by screws. The two wooden pieces are attached at a slight angle to the pole. The lower wooden piece is movable along the pole and has incised numbers. The wooden pieces are rectangular in shape with a large curved piece cut out to form the shape of a pennant. The maker's name is incised into the metal on the top attached wooden piece.

Instrument - Weights and Measures, Troy Weight Set, c 1865
... W x 1 mm Troy Weight Set Instrument Weights and Measures ...Troy weight is a system of units of mass from an unknown origin. While the name Troi is believed to have come from Troyes in the north east of France the system used primarily in the precious metals industry and adopted in Australia originated in 15th century England. Troy weight units are the 'grain' and 'pennyweight' (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). One troy ounce equals 31.1034768 grams. The troy ounce and grain were also part of the apothecaries' system and was long used in medicine, but has now been largely replaced by the metric system (milligrams). When the Weights and Measures Act was passed in Victoria in 1862 local inspectors were established throughout the colony to ensure accuracy particularly in the weighing of gold. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses. This set would have been de commissioned some time after 1947 and was offered back to the Borough of Eaglehawk in 1989. Hinged, lockable wooden box with brass handle, hinges, latches and lock. Remnant wax on front face of box above and below lock. Interior of box is lined with purple velvet which is worn in several places. Box houses nine troy weights ranging in size from 100oz Troy to 2oz Troy. 1oz Troy is missing.

Instrument - Scale, George Salter & Co, ca. 1886
... Government vessel Victorian Government measuring instrument weight ...There were at least three 1880s vessels named Lady Loch, all built in Victoria; a river launch (ca 1884 to ca 1916, originally named Lady of the Lake), a steamer ferry (1884 to 1920s), and a government lighthouse tender steamer HMV Lady Loch (1886 to 1962). The spring balance scale was part of the equipment on the HMV Lady Loch. The scale was made by the renowned company Salter Weighing Machines in the United Kingdom, to Silvester's patent design. Salter Weighing Machines, Britain, began making spring scales in the 1820s. In 1908 Salter opened up an Australian branch named Salter Scales Pty. Ltd. The scale is marked HMV SS Lady Loch. It would be suspended by its top ring, a basket or other container is hung from the hook, and the items inside the basket are then pulled downwards on the hook, which stretches the springs inside the works. The pulling action moves a rack and gears a calculated distance and the gears turn the pointer on the dial to indicate the weight of the goods. This scale measures up to 200 pounds capacity. The HMV SS Lady Loch was an iron steamship built in Footscray, Melbourne, by Campbell, Sloss and McCain in 1886 for the colonial Victorian government’s Department of Trade and Customs. It was armed with a 6-inch gun and two 1-inch Nordenfelt guns. The Sydney Morning Herald of 27th January 1888 describes the vessel in detail. It even comments on the interior of the Saloon “The wood work … is on a very elaborate scale and is exceedingly neat …”. The HMV Lady Loch performed Customs duties and serviced the lighthouses along the coast. The scale could have measured goods for the Customs Tax, or for measuring out supplies for the lighthouse keepers. The vessel was named after Lady Elizabeth Loch, wife of Sir Henry Loch, Governor of Victoria from 1884 to 1889. In 1932 Lady Loch was converted to a hulk and used in Brisbane, and finally scuttled in 1962 at Moreton Bay, Queensland.The scale has importance due to its connection to the 1886 HMV Lady Loch, a vessel of great significance to Melbourne’s shipbuilding industry. It was the largest auxiliary vessel in the Victorian Colonial Government’s fleet and the first prominent vessel launched by Melbourne’s shipbuilding industry. The scale is also important for its connection with the colonial navy's Custom's work, as the scale was available to weigh goods that could attract taxes and deal out goods for distribution to lighthouse keepers. The HMV Lady Loch was also important part of Victoria's maritime history for its communication and support of the lighthouse keeper's along the coast of Victoria.Scale; Salter's spring balance mechanical hanging scale, brass and iron. Equally spaced marks around the circular dial have values from 0 to 200 in increments of 10, each increment is also divided into 10. An iron ring is attached to a fitted loop on the top of the scale, and an iron hook is attached to the fitted loop onthe bottom of the scale. A moving pointer attached to the centre of the dial has a calibration screw joined to its base. Four screws fix the brass face to the works at the back. There are stamped and embossed inscriptions. Made by Salter in Britain, to Silvester's Patent design. The scale was once equipment carried abourd the steamship HMV SS Lady Loch.

Equipment - Lead line
The lead line or hand lead is a simple navigational instrument used as a depth finder to measure the depth of water under the ship’s keel and to take samples of the sea bed. The long line may be marked at regular intervals with tags of different coloured and textured fabric, such as rope, leather and cloth. Each tag was a code to represent a certain depth. The leadsman’s eyes and hands could distinguish the depth easily as he drew in the lead line, day or night and in poor weather conditions. A standard set of codes for the tags was used so that the depth of the sea could be easily and quickly read. The measurement used was a Fathom, which equals 1.83 metres. The codes were: - 2 fathoms = 2 strips of leather 3 fathoms = 3 strips of leather 5 fathoms = white duck fabric 7 fathoms = red bunting fabric 10 fathoms = leather with a hole 13 fathoms = blue serge fabric 15 fathoms = white duck fabric 17 fathoms = red bunting 20 fathoms = 2 knots The lead weight could be between 7 -14 pounds (3.5 – 6.5kg) and the rope would be approximately 25 fathoms (45m). The hollowed-out end of the weight would hold a stick substance such as tallow or wax, which would pick up samples from the sea bed which would show whether the vessel was close to, or far away from, the shore. The leadsman would stand at the front of the vessel and cast the lead line into the sea. When it hit bottom he would note the tag marker nearest the surface of the water and call out his finding. Then he would haul it up again and examine the kind of matter that adhered to the end of the weight, whether it be sand, mud, gravel, or the colour of it. This information would be given to the ship’s helmsman or navigator and would help indicate the proximity to the land.This handheld lead is an example of early marine navigational equipment used by sailors to travel the seas to measure the depth of the water and sample the nature of the seabed. It helps to understand the history and progress made from the very basic to the sophisticated technology of today.Lead line, sounding line or depth finder. The long length of rope has a heavy lead weight attached to the end. Coloured fabric tags are tied onto the rope at regular intervals, representing different depths. The concave base of weight holds sticky substances such as tallow or beeswax, providing an adhesive surface to collect samples of sea bed like sand, shells or pebbles. flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, lead line, depth finder, hand lead, sounding lin, leadsmane, navigation instrument, leadline, hand lead line -

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Temperature and relative humidity have major impacts on fuel dryness and therefore upon the availability of fuel for combustion. A thermo-hygrograph measures and records both temperature and humidity. It produces a continuous record by drawing ink traces on a paper chart held in revolving cylinder. Humidity is measured by shortening or lengthening of a bundle of specially treated human hair. Temperature is measured by means of a laminated bi-metal strip of temperature-sensitive metals which bend differentially with temperature change. The recording drum is driven by clockwork which may be geared for rotation intervals of daily, weekly or monthly periods. This particular instrument is a seven-day recorder.

Equipment - Postal Scales, Unknown
Before 1851, letters sent through the mail were charged by the number of sheets it contained and the distance it travelled. For example, a letter consisting of one sheet of paper was charged the single rate; a double letter, that is two sheets, was charged double the single rate, a treble letter, was charged three times the single rate, and so on. In other words, each additional sheet of paper increased the charge by one rate. In Great Britain. Sealing a letter in an envelope effectively put an end to postal clerks' ability to count the number of sheets in a letter and an alternative method of determining the postage had to be found. Overweight mailings had previously required the items to be weighed but with the introduction of the Uniform Penny Postage act of 1839, the public could mail a letter not exceeding a half-ounce in weight within the United Kingdom for one penny if prepaid, or two pence if paid on delivery. These postal scales belonged to Dr.William Roy Angus, Surgeon and Oculist. They were donated to Flagstaff Hill Maritime Village by his daughter, Bernice McDade. They are part of the “W.R. Angus Collection” that includes historical medical equipment, surgical instruments and material once belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) as well as Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969. ABOUT THE “W.R.ANGUS COLLECTION” Doctor William Roy Angus M.B., B.S., Adel., 1923, F.R.C.S. Edin.,1928 (also known as Dr Roy Angus) was born in Murrumbeena, Victoria in 1901 and lived until 1970. He qualified as a doctor in 1923 at University of Adelaide, was Resident Medical Officer at the Royal Adelaide Hospital in 1924 and for a period was house surgeon to Sir (then Mr.) Henry Simpson Newland. Dr Angus was briefly an Assistant to Dr Riddell of Kapunda, then commenced private practice at Curramulka, Yorke Peninsula, SA, where he was physician, surgeon and chemist. In 1926, he was appointed as new Medical Assistant to Dr Thomas Francis Ryan (T.F. Ryan, or Tom), in Nhill, Victoria, where his experiences included radiology and pharmacy. In 1927 he was Acting House Surgeon in Dr Tom Ryan’s absence. Dr Angus had become engaged to Gladys Forsyth and they decided he further his studies overseas in the UK in 1927. He studied at London University College Hospital and at Edinburgh Royal Infirmary and in 1928, was awarded FRCS (Fellow from the Royal College of Surgeons), Edinburgh. He worked his passage back to Australia as a Ship’s Surgeon on the on the Australian Commonwealth Line’s T.S.S. Largs Bay. Dr Angus married Gladys in 1929, in Ballarat. (They went on to have one son (Graham 1932, born in SA) and two daughters (Helen (died 12/07/1996) and Berenice (Berry), both born at Mira, Nhill ) According to Berry, her mother Gladys made a lot of their clothes. She was very talented and did some lovely embroidery including lingerie for her trousseau and beautifully handmade baby clothes. Dr Angus was a ‘flying doctor’ for the A.I.M. (Australian Inland Ministry) Aerial Medical Service in 1928 . Its first station was in the remote town of Oodnadatta, where Dr Angus was stationed. He was locum tenens there on North-South Railway at 21 Mile Camp. He took up this ‘flying doctor’ position in response to a call from Dr John Flynn; the organisation was later known as the Flying Doctor Service, then the Royal Flying Doctor Service. A lot of his work during this time involved dental surgery also. Between 1928-1932 he was surgeon at the Curramulka Hospital, Yorke Peninsula, South Australia. In 1933 Dr Angus returned to Nhill and purchased a share of the Nelson Street practice and Mira hospital (a 2 bed ward at the Nelson Street Practice) from Dr Les Middleton one of the Middleton Brothers, the current owners of what previously once Dr Tom Ryan’s practice. Dr Tom and his brother had worked as surgeons included eye surgery. Dr Tom Ryan performed many of his operations in the Mira private hospital on his premises. He had been House Surgeon at the Nhill Hospital 1902-1926. Dr Tom Ryan had one of the only two pieces of radiology equipment in Victoria during his practicing years – The Royal Melbourne Hospital had the other one. Over the years Dr Tom Ryan had gradually set up what was effectively a training school for country general-practitioner-surgeons. Each patient was carefully examined, including using the X-ray machine, and any surgery was discussed and planned with Dr Ryan’s assistants several days in advance. Dr Angus gained experience in using the X-ray machine there during his time as assistant to Dr Ryan. When Dr Angus bought into the Nelson Street premises in Nhill he was also appointed as the Nhill Hospital’s Honorary House Surgeon 1933-1938. His practitioner’s plate from his Nhill surgery is now mounted on the doorway to the Port Medical Office at Flagstaff Hill Maritime Village, Warrnambool. When Dr Angus took up practice in the Dr Edward and Dr Tom Ryan’s old premises he obtained their extensive collection of historical medical equipment and materials spanning 1884-1926. A large part of this collection is now on display at the Port Medical Office at Flagstaff Hill Maritime Village in Warrnambool. In 1939 Dr Angus and his family moved to Warrnambool where he purchased “Birchwood,” the 1852 home and medical practice of Dr John Hunter Henderson, at 214 Koroit Street. (This property was sold in1965 to the State Government and is now the site of the Warrnambool Police Station. and an ALDI sore is on the land that was once their tennis court). The Angus family was able to afford gardeners, cooks and maids; their home was a popular place for visiting dignitaries to stay whilst visiting Warrnambool. Dr Angus had his own silk worm farm at home in a Mulberry tree. His young daughter used his centrifuge for spinning the silk. Dr Angus was appointed on a part-time basis as Port Medical Officer (Health Officer) in Warrnambool and held this position until the 1940’s when the government no longer required the service of a Port Medical Officer in Warrnambool; he was thus Warrnambool’s last serving Port Medical Officer. (Masters of immigrant ships arriving in port reported incidents of diseases, illness and death and the Port Medical Officer made a decision on whether the ship required Quarantine and for how long, in this way preventing contagious illness from spreading from new immigrants to the residents already in the colony.) Dr Angus was a member of the Australian Medical Association, for 35 years and surgeon at the Warrnambool Base Hospital 1939-1942, He served as a Surgeon Captain during WWII1942-45, in Ballarat, Victoria, and in Bonegilla, N.S.W., completing his service just before the end of the war due to suffering from a heart attack. During his convalescence he carved an intricate and ‘most artistic’ chess set from the material that dentures were made from. He then studied ophthalmology at the Royal Melbourne Eye and Ear Hospital and created cosmetically superior artificial eyes by pioneering using the intrascleral cartilage. Angus received accolades from the Ophthalmological Society of Australasia for this work. He returned to Warrnambool to commence practice as an ophthalmologist, pioneering in artificial eye improvements. He was Honorary Consultant Ophthalmologist to Warrnambool Base Hospital for 31 years. He made monthly visits to Portland as a visiting surgeon, to perform eye surgery. He represented the Victorian South-West subdivision of the Australian Medical Association as its secretary between 1949 and 1956 and as chairman from 1956 to 1958. In 1968 Dr Angus was elected member of Spain’s Barraquer Institute of Barcelona after his research work in Intrasclearal cartilage grafting, becoming one of the few Australian ophthalmologists to receive this honour, and in the following year presented his final paper on Living Intrasclearal Cartilage Implants at the Inaugural Meeting of the Australian College of Ophthalmologists in Melbourne In his personal life Dr Angus was a Presbyterian and treated Sunday as a Sabbath, a day of rest. He would visit 3 or 4 country patients on a Sunday, taking his children along ‘for the ride’ and to visit with him. Sunday evenings he would play the pianola and sing Scottish songs to his family. One of Dr Angus’ patients was Margaret MacKenzie, author of a book on local shipwrecks that she’d seen as an eye witness from the late 1880’s in Peterborough, Victoria. In the early 1950’s Dr Angus, painted a picture of a shipwreck for the cover jacket of Margaret’s book, Shipwrecks and More Shipwrecks. She was blind in later life and her daughter wrote the actual book for her. Dr Angus and his wife Gladys were very involved in Warrnambool’s society with a strong interest in civic affairs. He had an interest in people and the community They were both involved in the creation of Flagstaff Hill, including the layout of the gardens. After his death (28th March 1970) his family requested his practitioner’s plate, medical instruments and some personal belongings be displayed in the Port Medical Office surgery at Flagstaff Hill Maritime Village, and be called the “W. R. Angus Collection”. At about the same time that the adhesive postage stamps and envelopes made their appearance, postal administrations began to experiment with strategically placed street letter boxes, known as pillar boxes because of their round, pillar-like shape, that permitted the public to mail letters from a place other than from a post office. For all these reasons, the use of postal scales became the nucleus of every post office. Scales had been in use since ancient Egyptian times so their use for everyday commerce was not unusual in the 1800s. What was new in 1840 was their ubiquitous use throughout the postal system. No post office could function effectively without one. Although the earliest scales used in post offices did not differ markedly from the ones in general use as time went on they were adapted specifically for postal use. For example, a paper sleeve, also known as a weight sticker, was attached that showed the applicable rate of postage for any given weight.
