The bundle includes handwritten records on pre-printed forms from the Commonwealth Government and brief records on plain paper. There are calculations for monthly totals of information such as rainfall, and there are some comparisons between the years. One of the forms has handwriting in three directions, which is quite unusual. Readings were recorded daily for barometer, temperature and wind. There was also a section for comments on Exceptional Phenomena such as storms and fog. . It was one of the many duties of the Lighthouse Keeper or his Assistant to keep these records and make the mathematical calculations required by the Government. Information gathered from Lighthouse Keepers' letters tells of the large amount of time taken for this detailed work and the lack of payment made for such a responsibility. The quite detailed record for May, June and July 1947 were signed by C Carrington, Harbour Master for Warrnambool. Captain Carrington was responsible to the Harborus Board. He was responsibilite for the fortnightly training of the Warrnambool Lifeboat Crew on the practice of lifesaving and using the Rocket Rescue equipment. These Meteorological Observations are an important accurate record of the local weather since the late 1899s. They are part of Flagstaff Hill's Meteorological Observations collection of over seventy record books dating from the late 19th century. The collected information gives a picture of the weather patterns for the months and seasons, which then allows for warnings of events out of the normal or extreme, such as forecasting floods or droughts.Meteorological Observations for Warrnambool March 1947 to May 1948. A bundle of unbound sheets of paper joined at the top left corner with a metal fastener. The pages are ordered from most recent on top to the oldest on bottom. The older records are on pre-printed forms and include many handwritten details. The more recent records are handwritten on plain paper.

Instrument - Barometer, Early 20th century
A barometer is an instrument used for measuring atmosphere pressure thus determining weather changes.The first apparatus generally accepted as a barometer was that set up in Florence in 1644 by Evangelista Torricelli (1608–1647), a mathematician and physicist. Torricelli filled a glass tube with mercury, sealed it at one end, and inverted it with its open end in a dish of mercury. The level always fell a short way down the tube, then settled at a height of about thirty inches. He concluded correctly that the mercury column was sustained by the weight of the air pressing on the open surface of mercury, and further experiments convinced him that the space above the mercury in the tube was a vacuum. He noted that the level rose and fell with changing temperature, but he was unable to use his apparatus to measure variations in the weight of the atmosphere because he had not foreseen that temperature would affect the level of the mercury. News of this experiment circulated quickly among European scientists, who hastened to replicate the experiment. Torricelli's conclusions were not universally accepted because some disputed whether the air had weight, while both Aristotle and the Catholic Church denied the possibility of a vacuum. In France, the philosopher René Descartes (1596–1650) seems to have been the first person, probably in 1647, to attach a graduated scale to the tube so that he could record any changes attributable to the weather. At around this time Duke Ferdinand II of Tuscany organized the first short-lived meteorological network among scientists in other Italian cities, gathering observations of pressure, temperature, humidity, wind direction, and state of the sky.Theis barometer is an example of a household item from the early 20th century, used to determine the day's weather. The barometer is significant as an aid to human social, material and scientific development.Barometer, round, brass housing inset into carved wooden casing (lacquer mostly worn off).

Barometer, 1858-1869
The barometer was either made or sold by T. Gaunt & Co. of Melbourne, a manufacturer, importer and retailer of a wide variety of goods including jewellery, clocks and watches, navigational and measuring instruments, dinnerware, glassware and ornaments. Thomas Gaunt photograph was included in an album of security identity portraits of members of the Victorian Court, Centennial International Exhibition, Melbourne, 1888. (See below for further details.) Admiral Fitzroy Pattern Barometer History: The stick mercury barometer was named after Admiral Robert Fitzroy of the Royal Navy (1805-1865) for his detailed instructions on how to interpret the weather, which were included with the instrument. Fitzroy was the captain of the HMS Beagle, also a weather forecaster to Charles Darwin and the second Governor of New Zealand. He developed many different types of barometers and was the first person to introduce the science of weather forecasting to the British Isles. A local manufacturer of scientific instruments, Thomas Gaunt, produced the barometer that was adapted for the southern hemisphere by Robert Ellery, the State Astronomer based at the Melbourne Observatory. In the original sale catalogue for Gaunt's, the item is described as "Gaunt's Fitzroy Barometers" and it was priced from 25/- to ₤9.9s. History of Thomas Gaunt: Thomas Gaunt established Melbourne's leading watchmaking, optical and jewellery business during the second half of the 19th century. Gaunt arrived in Melbourne in 1852, and by 1858 had established his own business at 14 Little Bourke Street. Around 1869 he moved to new premises in Bourke Street on the corner of Royal Arcade. Gaunt's shop quickly became a Melbourne institution. Gaunt proudly advertised that he was 'The only watch manufacturer in the Australian colonies'. While many watches and clocks may have had Gaunt's name on the dial, few would have been made locally. Gaunt did make some watches for exhibitions, and perhaps a few expensive watches for wealthy individuals. Gaunt's received a telegraph signal from Melbourne Observatory each day to correct his main clock and used this signal to rate and repair ship's chronometers and good quality watches. His main horological manufacturing was directed at turret clocks for town halls, churches and post offices. These tended to be specific commissions requiring individualised design and construction. He made the clock for the Melbourne Post Office lobby, to a design by Government Astronomer Robert Ellery, and won an award at the 1880-81 Melbourne International Exhibition for his turret clock for the Emerald Hill Town Hall. He became well known for his installation of a chronograph at Flemington Racecourse in 1876, which showed the time for the race, accurate to a quarter of a second. The firm also installed the clockwork and figures for Gog and Magog in the Royal Arcade. Thomas Gaunt also developed a department that focused on scientific instrumentation, making thermometers and barometers (from imported glass tubes), telescopes, surveying instruments and microscopes. Another department specialised in electroplating for trophies, awards and silverware, and the firm manufactured large amounts of ecclesiastical gold ware and silverware, for the church including St Patrick's Cathedral. There are no records that disclose the number of employees in the firm, but it was large enough for Gaunt to hold an annual picnic for the watchmakers and apprentices at Mordialloc from 1876; two years previously they had successfully lobbied Gaunt to win the eight hour day. Gaunt's workforce was reportedly very stable, with many workers remaining in the business for 15 to 30 years. Gaunt's wife Jane died on September 1894, aged 64. They had one son and six daughters, but only three daughters survived to adulthood. Two became nuns at the Abbotsford Convent and one daughter, Cecelia Mary Gaunt (died 28 July 1941), married William Stanislaus Spillane on 22 September 1886 and had a large family. Gaunt died at his home in Coburg, Victoria, leaving an estate valued at ₤41,453. The business continued as T. Gaunt & Co. after his death. The barometer is historically significant as an example of the work of Melbourne’s leading scientific instrument maker, Thomas Gaunt. The barometer has social significance as an example of the type of scientific equipment that Thomas Gaunt expanded his horology business into producing. Further social significance lies in the fact that Robert Ellery, the Government Astronomer who designed the local version of the barometer, had a direct connection with the Melbourne Athenaeum founded in 1839 as the Melbourne Mechanics' Institution. Its purpose was "the diffusion of literary, scientific and other useful information". There are also records of a T Gaunt as a subscription and committee member of this the Athenaeum organisation during the 1870s and 1880s which may be Thomas Gaunt, unfortunately still unverified.Stick mercury barometer known as the Admiral Fitzroy Barometer. It comprises an oblong wooden case with glass front panel, ornate pediment, barometer with bulb cistern (empty of fluid), cleaning brush with printed instructions for interpreting information given by the gauge affixed to left and right face of instrument.

Kiewa Valley Historical Society
Barometer Anoroid, circa mid to late 1900's
This barometer was part the hydrology and forestry groups working within the SEC Vic Hydro Scheme from the initial appraisal review long before any construction began in the 1940's. The river flows and rainfall patterns had to be established before any construction of holding dams or tunneling could commence. This barometer is very relevant to the Kiewa Valley history because it presents the high degree of professional and technical information required at the time before implementing the "Scheme" upon the virgin alpine region and its effects upon the "natural" flows of the rivers within the Kiewa Valley. Time since the start of the project has verified the use of instruments such as this barometer and the information gained from its use that the success of any large impact upon a sensitive environment requires a thorough and systematic study before implementation. Weather records were kept of temperature, wet-bulb temperature, wind direction, speed and barometric pressures. To record barometric pressure a meter was devised with a clockwork mechanism which took one week to do a revolution. A chart was fitted to a drum and had an ink pen shaped like a little shovel. The shovel was filled with ink and was checked daily. To calibrate the barometer it was sent to the Melbourne General Post Office to be compared against the one there (at sea level). After calibration it was sent back to the Bogong Camp.On plaque on top side."NEGRETTI & ZAMBRA" underneath this and in smaller print "TRADE MARK" below this "LONDON" On the bottom and in small print "HOBART DUFFPty Ltd COLLINS HOUSE MELBOURNE C1"kiewa hydro electricity scheme, victorian state electricity commission, transformers, resistors, barometers -

Gaunt died at his home in Coburg, Victoria, leaving an estate valued at ₤41,453. The business continued as T. Gaunt & Co. after his death. Post Office and Clock History: Warrnambool’s Post Office has been in existence since 1857, when it was originally situated on the corner of Timor and Gilles Street. In March 1864 the Warrnambool Borough Council purchased this clock from Henry Walsh Jnr. for the sum of £25, “to be put up in front of the Post Office”. Henry Walsh Jnr was the eldest son of Melbourne’s Henry Walsh, maker and retailer of clocks, watches, thermometers and jewellery. In 1854 Henry Walsh Jnr. began business in Warrnambool as a watchmaker and jeweller later becoming a Councillor with now a local street named after him. The Post Office was extensively remodelled in 1875-76. Early photographs of this building show that the clock was installed on the northern outside wall, Timor Street, under the arches and between the 2 centre windows, where it could be seen by passers-by. Although spring loaded clocks date back to the 15th century, and fob and pocket watches evolving from these date to the 17th century, personal pocket watches were only affordable to the very fortunate. Public clocks such as this Post Office clock provided opportunity for all to know the time, and for those in possession of a personal watch to check and set their own timepieces to the correct time. During post office reservations during the 1970s the clock was removed and was eventually donated to the Flagstaff Collection. The Clock’s maker Thomas Gaunt, is historically significant and was an established and well renowned scientific instrument and clock maker in Melbourne during the 1860s. He was at that time the only watchmaker in the Australian colonies. In the 1870’s and 1880’s he won many awards for his clocks and was responsible for sending time signals to other clocks in the city and rural areas, enabling many businesses and organisations to accurate set their clocks each day. Warrnambool Borough Council purchased this clock from Henry Walsh Jnr. for the sum of £25 and the clock used to stand in front of the Warrnambool post office to allow ordinary citizens to set their time pieces as they walked by. The item is not only important because it was made by a significant early colonial clock maker and retailed by a locally known clock maker and jeweler but also that it was installed in the Warrnambool Post Office a significantly historical building in it's own right. Built in 1857 and regarded as one of the oldest postal facilities in Australia, with a listing on the National Heritage Database, (ID 15656). This 1864 hall clock originates from the Warrnambool Post Office. The clock glass is hinged to the top of the clock face and has a catch at the bottom. The metal rim of the glass is painted black. The clock face is metal, painted white, with black Roman numerals and markings for minutes and five minutes. The tip of the small hour hand is shaped like a leaf. "T. GAUNT / MELBOURNE" is printed in black on the clock face. The winding key hole is just below the centre of the clock face. The key winds a fusee chain mechanism, attached to the brass mainspring barrel that powers the pendulum with an 8-day movement. The speed of the clock can be adjusted by changing the position of the weight on the pendulum, lengthening or shortening the swing; raising the pendulum shortens its swing and speeds up the clock. The metal fusee mechanism has an inscription on it. The rectangular wooden casing is with a convex curve at the bottom that has a hinged door with a swivel latch. The original stained surface has been painted over with a matte black. There are two other doors that also allow access to the clock’s workings. The case fits over the pendulum and workings at the rear and attaches to the clock by inserting four wooden pegs into holes in the sides of the case then into the back of the clock. A flat metal plate has been secured by five screws onto the top of the case and a hole has been cut into it for the purpose of hanging up the clock. There is a nail inside the case, possibly used for a place to the key."T. GAUNT MELBOURNE" is printed on the clock face. “6 1 3” embossed on the back of the fusee mechanism behind the clock. warrnambool, shipwrecked coast, flagstaff hill, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, shipwrecked artefact, clock, warrnambool post office, fusee, henry walsh jnr, thomas gaunt, t gaunt & co, post office clock -

Stick mercury barometer, named after Admiral Robert Fitzroy of the Royal Navy (1805 - 1865) for his detailed instructions on interpreting the weather that are included with the instrument. Fitzroy was the captain of the Beagle, a weather forecaster to Charles Darwin and the second Governor of New Zealand. He developed many different types of barometers and was the first person to introduce the science of weather forecasting to the British Isles. A local manufacturer of scientific instruments, Thomas Gaunt, produced the barometer and it was adapted for the southern hemisphere by Robert Ellery, the State Astronomer based at the Melbourne Observatory. Described as "Gaunt's Fitzroy Barometers" in the original sale catalogue, it was priced from 25/- to ₤9.9s. [See Miller, M., Gaunt’s Time, 2014]. Thomas Gaunt's business was originally located at 14 Bourke Street East from 1858. In 1869-1870 he moved to new premises in the Royal Arcade, Collins Street. Gaunt's business became an institution in Victorian Melbourne and Gaunt its leading clock maker. PROVENANCE According to official minutes the barometer was purchased by the Melbourne Athenaeum in 1874. In particular, at the March meeting of the General Committee the House Subcommittee was instructed to "obtain a Fitzroy or other reliable barometer" to be "fixed in the Reading Room". The 1874 Annual Report records the purchase at ₤3.10.0. The barometer is historically significant as an example of the work of Melbourne’s leading scientific instrument maker, Thomas Gaunt. The barometer has social significance as an example of the type of accoutrements provided by the committee of the Melbourne Athenaeum for the comfort of its members. Further social significance lies in the fact that Robert Ellery, the Government Astronomer, who designed the local version of the barometer, has a direct connection with the Athenaeum being a subscription member and committee member of the Athenaeum during the 1870s. There are also records of a T Gaunt as a subscription member of the Athenaeum during the 1870s and 1880s which may be Thomas Gaunt, however, this is yet to be verified.
