The Forest Fire Danger Index (FFDI) was originally invented by the grandfather of Australian bushfire science, Alan Grant McArthur, during the 1950s and ‘60s. Alan published his landmark paper, “Controlled burning in eucalypt forests” in 1962. Leaflet No. 80, as it was known, proved a turning point for forest and fire managers across Australia. More importantly, Alan was very practical forester and wanted his work to be useful to people in the field, so after several iterations he came up with the now familiar circular slide rule called the Forest Fire Danger Meter (FFDM). The Mk 4 version first appeared in operational use in 1967. This is the Mark 5 from 1992Alan McAthur's scientific legacy with the FFDI meter is unquestionably huge and has served forest firefighters very well over the decades.Control burning meter Series of circular slide rules to calculate Forest Fire Danger Index (FFDI)bushfire, forests commission victoria (fcv)

The firm Dring and Fage were active from 1790 to 1940 in London and were manufacturers of hydrometers and mathematical instruments they became established in London in 1790 by John Dring, who was a brass worker and hydrometer maker, and William Fage. Dring and Fage manufactured also saccharometers and other instruments used to measure the strength of alcohol. These instruments were primarily used to calculate excises. They traded at various addresses in London and they were at 56 Stamford St. between 1903 and 1938. By 1850 the company was owned by Edward Hall and Edward Jenkin and in 1940 the company became Dring & Fage Ltd, trading till the 1960s.Historically, gauging has meant measuring a volume, these gauging instruments were used by Customs and Excise and manufacturers for determining the volume and contents of liquid containers. For Customs the determination and collection of duty on imported goods which has had a very long history. Chaucer was a Customs Officer as was his father and grandfather, excise was first officially introduced in 1643, with the aim of maintaining military forces raised by the English Parliament at that time. Excise was initially a duty on home produced alcoholic beverages and soap but being easily applied, spread rapidly to a wide range of goods including imports of varying kinds. The government departments of Customs and Excise merged only in 1909 and it is from around this time that our instrument was made and used. The item demonstrates a long social history of the practice of Government's collecting duty on alcoholic beverages and thereby makes this item historically significant as it was used locally at Port Fairy by the ports Customs agents.

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.

Two Forests Commission staff, Athol Hodgson and Rus Ritchie, built on McArthur’s pioneering work and by applying their own practical experience, developed a modified version in the late 1960s called the Control Burning Meter which was better suited to Victorian forest conditions.Introduced to the FCV in 1970Control burning meterbushfire, forests commission victoria (fcv)

Decimal currency was spectacularly introduced in an overnight overthrow on 14 February 1966, but it took another 8 years before metrication finally arrived in the forest and timber industry. Eventually, the measurement of logs and sawn timber changed from imperial, and excruciating, measures such as super feet of sawn timber, billets and cunits (100 cubic feet) of stacked pulpwood and hoppus log volumes to simpler cubic metres. Measuring firewood was a particular nightmare. For example, there were standard chords, stove cords, kitchen cords, running cords, face cords, thrown chords, fencing cords, country cords, long cords, raummeter or steres (1m x 1m x 1m). A standard cord of firewood had a volume of 128 cubic feet, measured as a pile 8 feet long, 4 feet high and 4 feet wide (3.624 m3). And how about this for confusing…. in Victoria, an imperial or long ton (by measure) of green firewood was a stack 5 feet long billets (2 axelengths at 2′ 6″ each), one axelength high (2′ 6″) and two axelengths long (5 feet) equalling 62.5 cubic feet. For added befuddlement, there were three different sorts of tons: Imperial tons or long tons, American short tons and metric tonnes (spelled with two n’s). Not forgetting that a cubic imperial ton of firewood (40 cubic feet) which equalled 1.133 cubic metre. The metrication process began in 1974 and was completed by 1976 but the transition was not without its challenges along the supply chain for foresters, overseers, logging contractors, sawmillers, hardware stores and builders alike. Timber lengths changed from feet to metres but were still sold in multiples of one foot or 0.3 m (1.8, 2.1, 2.4, 2.7 etc) whereas a menacing lump of 4-Bee-2 transformed into a rather less colourful 100mm by 50mm. Measurement and calculations of area also became so much easier in hectares rather than complicated acres, roods and perches. The Forest Metriverter slide-rule was issued by the Forestry and Timber Bureau to make metric conversions easier.Forest MetriverterRoss Pennyforest measurement, surveying, forests commission victoria (fcv)

This image shows six older Chinese men standing in a row with two younger non-Chinese men outside a small wooden business or official building in the Beechworth region, circa 1900. The two non-Chinese men are wearing clothes of the period that indicate relative prosperity (such as three piece suits, top hats, and a pocket handkerchief), whereas most of the Chinese men are wearing Western-style working clothes of the era. One Chinese man at the far right of the image is wearing similar garments to the non-Chinese men, including a bowler hat and longer, more tailored suit jacket. Chinese miners were a significant cultural group in Beechworth's gold rush period. Carole Woods' history of Beechworth, 'A Titan's Field', details that there were approximately 60 Chinese people in the area in 1855, more than 1000 in 1856 and 4700 (a quarter of the population) in 1857, despite the introduction in 1855 of official policies such as additional taxes formulated by the Victorian Government to limit access by Chinese immigrants. Most Chinese miners in the region came from southern China and had formerly worked as merchants, mechanics, farmers and shop-keepers. Chinese people were subjected to a 'protectorate' system, ostensibly to minimise the potential for conflict with other groups; this system required Chinese people to live in designated 'hygienic' camps with paid Chinese headmen who supervised the village and enforced the protectorate's rules. Chinese people were required to purchase an annual protection ticket to fund this system. The protectorate system was abolished in 1861, before this image was taken in approximately 1900, but it may still provide insight into social stratification or relationships between and within cultural groups in Beechworth resulting from such practices. Lantern slides, sometimes called 'magic lantern' slides, are glass plates on which an image has been secured for the purpose of projection. Glass slides were etched or hand-painted for this purpose from the Eighteenth Century but the process became more popular and accessible to the public with the development of photographic-emulsion slides used with a 'Magic Lantern' device in the mid-Nineteenth Century. Photographic lantern slides comprise a double-negative emulsion layer (forming a positive image) between thin glass plates that are bound together. A number of processes existed to form and bind the emulsion layer to the base plate, including the albumen, wet plate collodion, gelatine dry plate and Woodburytype techniques. Lantern slides and magic lantern technologies are seen as foundational precursors to the development of modern photography and film-making techniques.This glass slide is significant because it provides insight into Beechworth's cultural and social relationships in the early Twentieth Century, in particular the experiences of Chinese miners. It is also an example of an early photographic and film-making technology in use in regional Victoria in the time period.Thin translucent sheet of glass with a circular image printed on the front and framed in a black backing.
