This Sike’s Hydrometer was donated by the Port Fairy Customs Office as it was no longer required by them due to a change in the law. The hydrometer was part of a system for Ullaging or calculating the amount of liquid remaining in a container of liquor such as a barrel, and the amount of alcoholic content in the contents. It can also measure the free space or head space remaining. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid.The Sikes hydrometer is of local significance because of its association with the Government's Customs Office in Port Fairy, in the southwest region of Victoria. It is also associated with Bartholomew Sikes, whose design of a hydrometer was chosen in 1816 as being the most useful and accurate hydrometer. The hydrometer has evolved into the digital version available today to measure density of liquids.Sikes Hydrometer and thermometer in a fitted wooden case with crimson lining inside the lid and dark lining in the base. The case has ten vertical pegs to secure the weights. The brass hydrometer has a spherical float and eight thick brass horseshoe-shaped weights. The serial number is on each section of the float and all weights. Both sides of the float’s upper flat stem have a scale from 0-10, with five divisions between each number. The eight weights are numbered from 20 – 90 in increments of 10. The set includes a mercury thermometer mounted on an ivory back plate labelled with Fahrenheit and Centigrade Scales. The Sikes hydrometer set was made by Loftus of London. The hydrometer model is IID 510, Serial Number is 14674, calibrated by Longs, London. All parts of the float and eight weights are inscribed with Serial Number “14674” The float stem is stamped "SIKE'S IID 51o” Calibrator, "LONG LITTLE TOWER ST LONDON" The weights are numbered individually ”20”, “30”, “40”, “50”, “60”, “70”, “80” or “90” Each weight in inscribed; symbol “(J L) [inside an ova, with textured background]” The thermometer inscribed: “LOFTUS OF LONDON”flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, measuring instruments, customs tax, weighing instrument, sike’s hydrometer, calibrator long of london, loftus of london instrument maker, loftus, j long, sikes hydrometer, scientific instrument, pressure measurement, measuring instrument, ullage tool, customs, excise duty, tax, alcohol content, proof, calibrate, standard weights and measures, tariff, scientific instrument makers, specific gravity, liquid density, alcohol testing, technology, alcohol measurement, proof spirit, wine and spirits merchants, local business, brass measuring instrument, port fairy, customs office, port fairy customs, joseph long, instrument maker

The Australian Customs Service, Melbourne, donated a set of gauging instruments, and Port Fairy Customs donated another instrument, the Sike’s Hydrometer, to Flagstaff Hill Maritime Village, all of which were no longer required. However these ullaging tools were in use for many years by Customs officials, called Gaugers. Ullaging is a term describing the measurement of the amount of liquid remaining in a container of spirits such as a cask or barrel. It can also measure the free space or head space remaining. The primary role of customs officers in Victoria was to calculate the tariff or excise duty payable on goods imported into Victoria. (Excise duty is a tax on goods produced within a country, and customs duty is imposed on imports.) Customs officers spent a great deal of their time measuring and weighing goods, and then calculating the amount of duty to be paid by the importer. The tariffs for different products varied, and officers consulted published lists. Calculating the duty payable on a barrel of brandy was a detailed task. The gauger had to measure the barrel to determine its volume. Barrels were irregular in shape, and finding the volume required several measurements and checking tables of figures. Alcoholic content was then measured with a hydrometer. The duty paid varied according to the alcoholic strength of the spirits. Uniform national customs and excise duties were operative in Australia from October 1901. These tools were still being used in Australia in the 1950’s. The Federal Government still imposes excise taxes on goods such as cigarettes, petrol, and alcohol. The rates imposed may change in February and August each year in response to changes in the consumer price index. ULLAGING TOOLS (1) Head Rod - this instrument measures the diameter of the heads (top and bottom ends) of a cask or barrel. The shaped brass pieces on the head rod enable the diameter of a barrel to be measured inside the chimes at the head end. The slide rule could then be used to calculate the internal volume of the barrel. On the reverse side is a set of ullaging scales, used like those on any ullaging rule, to calculate the volume of liquid in a partially filled barrel. (2) Bung Rod – this instrument measures the diameter of a cask or barrel when it is lying on its side. It is a rod that fits into the ‘bung’ hole of a cask and is long enough be extended to reach the opposite side of the cask. The brass sliding pointer can be moved to mark the ‘wet’ line. When the rod is removed the bung measurement can be read from the scale on the rod. (3) Long Calipers - this instrument measures the length of the cask between the heads. It has two rules sliding beside each other, each end having another piece of wood fixed firmly at right angles downwards then turned inwards at the ends so as to reach over the heads of the casks without touching the projecting ends. The centre pieces enable it to extend or contract, changing the distance between the two other parallel sides, the distance they are apart being shown by the rule on the sliding pieces. (4) Cross Calipers – this instrument is used to take the bung diameters of casks, or "the Cross " as it is called. This instrument has two rules sliding beside each other, each end having another piece of wood fixed firmly at right angles downwards, together forming a 3 sides of a rectangle with the centre pieces enabling it to extended or contracted, changing the distance between the two other parallel sides, the distance they are apart being shown by a the rule on the sliding pieces. (5) Sike’s Hydrometer – this instrument is used to gauge the strength of different alcoholic spirits when fitted with the different weights in the set. Every set is individually calibrated to ensure that it meets the exact Standard Weight and Measure compliance, then every piece in that set is stamped with the same number by the Calibrator, to ensure that the measurements are taken using the same hydrometer set.

This tiny picturesque building near the corner of John Street has served the community since 1878. At that time it served as an agency of the Heidelberg branch of the Commonwelath Bank of Australia. It has a small space inside measuring about 3.6 metres by 4.5 metres. It was built by George Stebbing who was also responsible for other heritage buildings nearby in Eltham. Covered under Heritage Overlay, Nillumbik Planning Scheme. Published: Nillumbik Now and Then /​ Marguerite Marshall 2008; photographs Alan King with Marguerite Marshall.; p93 The tiny picturesque building on Main Road, Eltham, near the corner of John Street, has served the community since 1878. At that time the building, which inside measures only about 3.6m by 4.5m served as an agency of the Heidelberg branch of the Commercial Bank of Australia. The yellow and orange Victorian brick structure was built by Mr George Stebbing.1 Mr Stebbing, who also built the Anglican and former Methodist churches and the Shillinglaw Cottage, had come from England and lived in Pitt Street. The bank is a fine example of a once common but now rare building style – the single room bank. It compares with another in the municipality, also a former Commercial Bank of Australia branch, the timber Little Bank Building in Hurstbridge, built around the early 1900s.2 The Eltham bank, which was said to store gold from the Eltham - Research mining areas, has had exciting moments. A bullet hole still visible in a cedar bench testifies to the drama in 1949 when a youth held up the bank. After the 19-year-old opened an account as John Henderson, he walked to the door and then turned pointing a pistol. But it was shots fired by the clerk, Lindsay Spear, that saved the day, frightening the youth, who drove off empty-handed in a grey sports car. He was later apprehended and given a two-year sentence. Soon afterwards the agency was upgraded to a branch. However by 1954 the bank no longer needed the branch and the adjoining Methodist Church bought the building. It proved useful for the Church’s young people who furnished it and used it for their meetings. A youth club developed, led by young adult member, Ross Gangell. The building was also used as a Sunday School, which with junior membership numbered 27.3 Around 1960, Mrs Alma Bell, of the Methodist Church Women’s Guild, suggested using the building as an opportunity shop to raise funds for a chaplain at the Eltham High School. The women later asked the nearby St Margaret’s Anglican Church to help them in the shop. In 1960 the Eltham Combined Churches Opportunity Shop was established and staffed by Methodist and Anglican parishioners, notably Methodist Mrs Gwen Miller. The shop originally opened on Child Endowment Days to help the needy, but later for years, it opened twice a week. In 1962 it donated clothing and shoes to the Eltham Bushfire Appeal. By 1963 the chaplaincy scheme ceased. So the £450 raised was then donated to the Council for Christian Education and to the participating churches. Funds were also donated to local charities including the Eltham and Research Fire Brigades, the Austin Hospital Auxiliary, the Benevolent Society, the Red Cross and the Diamond Valley Hospital.4 In 2008 the Opportunity Shop volunteers continue to work together to help the local community. Although crammed with second-hand goods, the simple, almost stark interior, is still evident and is relieved only by a front rectangular window and an unused fireplace. Outside, the chimney, the corrugated iron peaked roof, and the surrounding varied plants, add to the charm of this sound building which continues to serve the community well.This collection of almost 130 photos about places and people within the Shire of Nillumbik, an urban and rural municipality in Melbourne's north, contributes to an understanding of the history of the Shire. Published in 2008 immediately prior to the Black Saturday bushfires of February 7, 2009, it documents sites that were impacted, and in some cases destroyed by the fires. It includes photographs taken especially for the publication, creating a unique time capsule representing the Shire in the early 21st century. It remains the most recent comprehenesive publication devoted to the Shire's history connecting local residents to the past. nillumbik now and then (marshall-king) collection, cba bank

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).

There were at least three 1880s vessels named Lady Loch, all built in Victoria; a river launch (ca 1884-ca 1916, originally named Lady of the Lake), a steamer ferry (1884-1920s) and a government lighthouse tender steamer HMV Lady Loch (1886-1962.) 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. It was made 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, marked HMV SS Lady Loch, would be suspended by its top ring, a basket or other container is hung from the hook, and the items inside the basket then pull 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.

Take a stroll through the average beverage aisle in your supermarket, and you might get the impression that tea has always come in small boxes with disposable tea bags. But before those easy to come by boxes, there was the rich and intriguing history of the tea strainer, a beautiful little tool that has helped our ancestors enjoy loose leaf tea for hundreds of years. Enjoying loose-leaf tea, and becoming familiar with this tool, can help spark an appreciation for your tea strainer and infuser collection, or simply inspire you to grow one. Documentation of tea tools such as the tea strainer appear in ancient history, the earliest models were likely made of bamboo, and later evolved into stainless steel, sterling silver, china, porcelain, silicon, and linen. During the Tang Dynasty in China, a small book called “Classic of Tea” was written describing tea utensils, and they were made to help Buddhist monks keep living things (such as small bugs) out of the drinking water. However, using a tea tool to keep run away tea leaves out of a cup did not become a cited use of the strainer until the 17th century when Dutch merchants made tea more readily available to those outside of the Chinese dynasty. British royals then increased the popularity of tea as their preferred beverage, and it was not long before a newfound fanaticism for tea in Great Britain spread to the American colonies, as did a growing demand for products that could separate loose tea leaves from liquid with ease and flair. Why did people use a strainer to separate out tea leaves in Great Britain and not in China? While the method of serving tea from a teapot with the tea loose in the pot was a practice used in both countries, the reason China may not have required a tool to remove leaves from their cup likely had to do with the types of tea leaves they were producing. The British owned tea plantations, in countries such as India, produced finer black tea leaves that did not require as much space to expand inside of a tea pot, where as the leaves prepared on the Chinese plantations would expand far more in the pot, and were therefore less likely to land or be bothersome inside a tea cup. This common approach to serving tea with smaller tea leaves required a solution to avoid ending up with a cup, and mouth, full of tea leaves. The obvious solution was a strainer basket. In the Victorian era, tea strainer baskets, similar to those still used in tea parlors today, were made to sit on top of the cup to capture the leaves when pouring the tea from a tea pot into the individual cups. Another solution was a tea-removing device called a mote spoon. Mote spoons act as search and rescue spoons to remove tea leaves from individual teacups. The tea would be brewed loose in the teapot, so any tea that ended up in the cup could be removed with a long handled spoon with holes in the spoon to remove rogue tea leaves and keep the steeped water in the cup. The handle also helped keep the teapot spout free of leaves and could help unclog any leaves trapped when pouring. Stainless steel tea strainers and tea infusers gained popularity in the late 19th century. Big name tea strainer producers, such as Tiffany and Gorham, could use fine silver to create quality, heavy, and sturdy strainers, for those who could afford it. There were many varieties of strainers at that time, but it was more likely that smaller designers who could not afford to mass-produce these quality strainers out of silver made them into unique shapes to attract consumers with lighter wallets. And borne was the tea strainer we are accustomed to today. Things took an unexpected turn for the tea strainer in the early 1900s when Thomas Sullivan, a tea merchant, shipped out tea samples in small silk bags. Customers did not realize that they were supposed to remove the tea from the bags, and instead boiled the tea, bag and all! The convenience of tossing out the leaves is obvious, and the popularity of tea bags is still seen today. Most premium bags of tea we are accustomed to today are frequently packaged loose for consumption, and when they are available in bags, the leaves are often crowded and do not have enough space to expand. While pyramid tea bags have become a more recent solution to this problem, due to the additional space at the top of the bag, enjoying a variety of quality tea is easier with a tea strainer in your arsenal. Besides, with the wide variety of strainers for your cup or pot in versatile materials such as mesh, silver, or a novelty silicone cartoon shape, loose tea can still reign supreme. Tea strainers sometimes do require more cleanup and measuring, but the experience and quality is always worth the effort. Besides, strainers also allow for mixing favorite tea blends together for an extra dose of delicious creativity! https://www.teamuse.com/article_170413.html The strainer provided the convenience of separating the tea leaves for disposal later.Metal strainer, bowl shaped, with mesh and twisted wire handle.Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, strainer

Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.

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.

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. Glass sits in a brass collar at each end, in a frame comprising 3 decorative brass columns or posts, each attached top and bottom, using round screw-on feet, to round brass discs.

Kangaroo Ground's first school began in 1851 with 22 pupils from the district's ten families. It was a single room school located further south on the site, which also served as a Presbyterian church. The first teacher was Andrew Ross. The school building was used as a Post Office between 1854 and 1858 and during 1857 also served as a Court of Petty Sessions. With a growing farming community, a new building was warranted and the original Sate School No. 352 was closed and a new building, State School No. 2105 was oipened October 1, 1878. A residence for Head Teacher Henry Wallace School was erected in 1879 attached to the left of the school building. That residence is now home to the Andrew Ross Museum, which opened in 1993.

Published: Nillumbik Now and Then /​ Marguerite Marshall 2008; photographs Alan King with Marguerite Marshall.; p35 In a corner of the Kangaroo Ground Primary School playground stands an old weatherboard building. This structure, attached to the former teacher’s weatherboard residence facing Main Road, first served as a school in 1878. The former residence, built in 1879, houses the Andrew Ross Museum, which opened in 1993. It is named after the school’s first teacher,1 who also founded The Evelyn Observer newspaper, which began on the site in 1873. Later the printing presses were moved to brick newspaper offices by the Kangaroo Ground Hotel, which became the Shire of Eltham offices. However Kangaroo Ground’s first school began in 1851 for 22 pupils from the district’s ten families, in a slab building further south on this site. Andrew Harkness and other settlers campaigned for the building, which was built on half an acre (0.2ha) donated by local farmer, James Donaldson. Builder was Samuel Furphy, father of the novelist Joseph.2 The single room measuring 30 feet x 18 feet (9m x 5.5m), was unlined and the green slabs shrank, allowing the wind and rain entry through cracks except when they were stuffed with paper.3 The building served as a Presbyterian church as well as a school, where fees were 18 pence a week for education. Young men also attended evening classes there in winter. At one stage, a corner of the room was curtained off for the schoolmaster’s living space, and the platform, which was used for sleeping, was also the pulpit during church services. Teacher Andrew Ross also took church services when the minister was unable to attend, which happened frequently as he had long distances to travel on the bad roads. In 1857 the school building was also used as the Court of Petty Sessions, and from 1854 until 1858, it served as a post office. During the gold rush fossickers on their way to the Caledonia Diggings at Queenstown (now St Andrews) prospected the district, but did not remain long, as the fields were not rich in gold. But the farming community grew, until by 1878 the population warranted the building of State School No 2105 – the present one-roomed tongue-and-groove lined building measuring 49 feet x 18 feet (15m x 5.5m), to accommodate 60 children. The old school, No 352, was closed, and the new one opened on October 1, with Henry Wallace as head teacher, assisted by work mistress Annie Johnston. Early teachers included Messrs Smith, Hamilton and Prosser, with sewing teachers Misses Sweeney, Limerock and Oliver. In the early 1920s a small room was built on the front veranda of the teacher’s residence, and used as a State Savings Bank agency until about 1934. In 1928 the schoolroom’s three-tiered floor was replaced by a flat floor and teacher’s platform (which has since been removed). A half-glassed partition wall then divided the large room into two rooms in which the old style form-type desks were replaced with dual desks. The small playground, surrounded by pine trees and a picket fence, was extended in 1931 with an additional acre or so (0.4 ha) of land. During World War Two the school faced closure because of a fall to seven in the enrolment, but by 1946 it had increased again to 45. Mr Eric Morgan was head teacher and Mrs Margaret Banks was assistant head teacher, a position she held for ten years. In 1955, under the head teacher Mr V Gardiner, who taught there for 13 years, the school won a prize for the best-kept garden and school ground in the inspectorate. A district subdivision increased the enrolment in 1968 to 65 and a bus service was established. After the hall which had been used for lessons was demolished late that year, the pupils met in the original fire brigade meeting room (now the tennis club, diagonally opposite the general store). The new school building with a storeroom and staffroom was built in 1974.This collection of almost 130 photos about places and people within the Shire of Nillumbik, an urban and rural municipality in Melbourne's north, contributes to an understanding of the history of the Shire. Published in 2008 immediately prior to the Black Saturday bushfires of February 7, 2009, it documents sites that were impacted, and in some cases destroyed by the fires. It includes photographs taken especially for the publication, creating a unique time capsule representing the Shire in the early 21st century. It remains the most recent comprehenesive publication devoted to the Shire's history connecting local residents to the past. nillumbik now and then (marshall-king) collection, kangaroo ground, andrew ross museum, eltham-yarra glen road, kangaroo ground primary school no. 2105, kangaroo ground state school, state school no. 2105
