The peck has been in use since the early 14th century when it was introduced as a measure for flour. The term referred to varying quantities until the modern units of measurement were defined in the 19th century. Cities in England used to have official standard weights and measures for that city or area. These containers were marked with the city's name and emblem, merchant’s weights and measures would then be checked against this to make sure they weren't trying to cheat their customers. The item in the collection is a standard measure approved by Bristol City and used by that City’s grocers to measure dry goods such as peas, beans, sugar, flour, meal etc., and its metal banding ensures that the measure cannot be reduced in size to cheat customers. Additional Information: The British Imperial System evolved from the thousands of Roman, Celtic, Anglo-Saxon, and customary local units employed in the middle Ages. Traditional names such as pound, foot, and gallon were widely used, but the values so designated varied with time, place, trade, product specifications, and dozens of other requirements. Early royal standards were established to enforce uniformity took the name Winchester, after the ancient tenth century capital of Britain. King Henry VII reaffirmed the customary Winchester standards for capacity and length and distributed royal standards throughout the realm. This process was repeated about a century later in the reign of Queen Elizabeth I. In the 16th century, the rod (5.5 yards, or 16.5 feet) was defined (once again as a learning device and not as a standard) defined by the length of the left feet of 16 men lined up heel to toe as they emerged from the church. By the 17th century usage and legal statute had established the acre, rod, and furlong at their present values together with other historic units such as the peck. Establishment of the System: The Weights and Measures Act of 1824 and the Act of 1878 established the British Imperial System based on precise definitions of selected existing units. The 1824 act sanctioned a single imperial gallon to replace the wine, ale, and corn (wheat) gallons that were in general use. The new gallon was defined as equal in volume to 10 pounds avoirdupois of distilled water weighed at 62°F with the barometer at 30 inches, or 277.274 cubic inches (later corrected to 277.421 cubic inches). The two new basic standard units were the imperial standard yard and the troy pound, which was later restricted to weighing drugs, precious metals, and jewels. In 1963 an act of parliament abolished archaic measures as the rod and chaldron and a metric system was adopted. An early example of a dry measuring container giving a snapshot of how imperial weights and measures developed in England to evolve the British measurement system into the metric arrangement that most countries have adopted today including Australia. It has social significance as an item that was in everyday use by grocers and other merchants to measure dry goods in the late 18th to early 19th centuries and used specifically in the Bristol region of England as an officially recognised measurement.Wooden measurement container with iron banding and hand made rivets container is a Quarter Peck official measurement container.

The beginning of standardised weights and measures began In Victoria when the Melbourne Observatory received sets of standard weights and measures, which had been tested in Britain against the then British Imperial standards. These included the primary standard yard and pound for the Colony of Victoria. Other standards of weights and measure held by shires and the administrative body's within the colony could then be compared to these primary standards. A Weights and Measures Act was passed in Victoria in 1862, establishing local inspectors throughout the colony. By the 1870s each local council and shire in Victoria held a set of standards that were used to test scales, weights and dry measures used by wholesalers, factories and shops. Every ten years the councils’ standards would themselves need to be rechecked against the Victorian Standards. The checking was done by the Victorian Customs Department in the 19th century, but with the transfer of responsibility for customs to the Federal Government in 1901, weights and measures function was retained by the Victorian Government and was shifted to the Melbourne Observatory. In 1904, a new building was erected at the south end of the Great Melbourne Telescope House, where the standard weights and measures and testing equipment was installed. This room had a large whirling apparatus for testing air meters and became known as the Whirling Room. When the Melbourne Observatory closed in 1944, the Weights and Measures Branch was formed to continue and this branch remained at the Observatory site unit until 1995. J & M Ewan History: J&M Ewan was a Melbourne firm that began by selling retail furniture and wholesale ironmongery. They had substantial warehouses situated at the intersection of 81-83 Elizabeth and Little Collins Streets, the business was established by James M Ewan in 1852. Shortly afterwards he went into partnership with William Kerr Thomson and Samuel Renwick. When Ewan died in 1868 his partners carried on and expanded the business under his name J & M Ewan. The business was expanded to provide a retail shop, counting-house and private offices. Wholesale warehouses adjoined these premises at 4, 6 and 10 Little Collins Street, West. This company provided and sold a large and varied amount of imported goods into the colony that consisted of agriculture equipment, building materials, mining items as well as steam engines, tools of all types and marble fireplaces. They also supplied the Bronze measuring containers in the Flagstaff Hill collection and the probability is that these containers were obtained by the local Melbourne authority that monitored weights and measures in the mid to late 19th century. The company grew to employ over 150 people in Melbourne and opened offices at 27 Lombard St London as well as in New Zealand and Fiji. The company also serviced the Mauritius islands and the pacific area with their steamship the Suva and a brig the Shannon. Robert Bate History: Robert Brettell Bate (1782-1847) was born in Stourbridge, England, one of four sons of Overs Bate, a mercer (a dealer in textile fabrics, especially silks, velvet's, and other fine materials)and banker. Bate moved to London, and in 1813 was noticed for his scientific instrument making ability through the authority of the “Clockmakers Company”. Sometime in the year 1813 it was discovered that one Robert Brettell Bate, regarded as a foreigner in London had opened a premises in the Poultry selling area of London. He was a Mathematical Instrument maker selling sundials and other various instruments of the clock making. In 1824, Bate, in preparation for his work on standards and weights, leased larger premises at 20 and 21 Poultry, London, at a rental of four hundred pounds per annum. It was there that Bate produced quality metrological instruments, which afforded him the recognition as one of one of the finest and principal English metrological instrument-makers of the nineteenth century. English standards at this time were generally in a muddle, with local standards varying from shire to shire. On 17 June 1824, an Act of Parliament was passed making a universal range of weights, measures, and lengths for the United Kingdom, and Bate was given the job of crafting many of the metrological artifacts. He was under instruction from the renown physicist Henry Kater F.R.S. (1777-1835) to make standards and to have them deposited in the principal cities throughout the United Kingdom and colonies. Bate experimented with tin-copper alloys to find the best combination for these items and by October 1824, he had provided Kater with prototypes to test troy and avoirdupois pounds, and samples with which to divide the troy into grams. Bate also cast the standard for the bushel, and by February 1825, had provided all the standards required of him by the Exchequer, Guildhalls of Edinburgh, and Dublin. In 1824, he also made a troy pound standard weight for the United States, which was certified for its accuracy by Kater and deposited with the US Mint in 1827. Kater, in his address to the Royal Society of London, acknowledged Bate's outstanding experimentation and craftsmanship in producing standards of weights, measures, and lengths.

Scales such as the subject item were used to measure commercial quantities, possibly grains and farm produce for quite large amounts of product. Bags of grain etc would have been hooked up and weighed. Salter has been a name long associated with weights and measures. The firm began life in the late 1760s in the village of Bilston, England when Richard Salter, a spring maker, began making the first spring scales in Britain. He called these scales "pocket steelyards", though they work on a different principle from steelyard balances. By 1825 his nephew George had taken over the company, which became known as George Salter & Co. George later established a manufacturing site in the town of West Bromwich, about 4 miles (7 km) from Bilston. West Bromwich Albion football club was formed from workers at this works site. From here the company produced a wide variety of scales including the UK's first bathroom scales. Other items were added to the range, including irons, mincers, potato chippers, coin-operated machines and the first typewriters made in the UK. The business thrived throughout the 1900s, and by 1950 it employed over 2000 people, still in the same area and owned by the same family.Salter is a British housewares brand developing products that span a wide range of core product categories, including scales, electrical, cookware. It is a market leader in kitchen and bathroom scales and one of the UK’s oldest consumer brands.  Established in 1760, Salter has been developing precision products for over 260 years. It was acquired by Manchester-based consumer goods giant Ultimate Products in 2021 after they had previously licensed the brand for cookware and kitchen electrical since 2011.Balance scale Salters Spring Balance consisting of a circular, bronze face engraved with measurements in pounds, with an iron hand, weighing mechanism and hanging loop.

Used to mince fuel samples to measure moisture content Representative samples of fuel such as bark, leaves, twigs etc were minced and the moisture measured The availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme. During the afternoon of the Ash Wednesday bushfires on 16 February 1983 fuel moisture contents were recorded at Stawell as low as 2.7%. Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out.

Bushfire behaviour is influenced by many things including temperature, relative humidity, forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), and also bushfire size, shape and direction. Fuel arrangement is as important as fuel quantity (tonnes/ha). Fibrous and ribbon bark, together with elevated and near-surface scrub fuels act as ladders which lead flames into the tree canopy. But the availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme.

Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out. Since the 1930s foresters, firefighters and researchers have been working to develop quick and reliable techniques for measuring fuel moisture content. One of the most accurate methods is slowly drying a sample of fuel in a conventional oven for 24-48 hours to remove all the moisture and measuring the weight difference, but this takes time and is not practical in the field when rapid measurements are needed. But oven drying is often used as a benchmark to compare other methods. Microwave ovens are faster but can cause uneven drying and even char the fuel. They are also not very practical for use in the field. Some mathematical models rely on weather records such as rainfall, wind speed, evaporation, cloud cover, shading, relative humidity, slope, aspect and season of the year to predict soil and fuel moisture. The Keetch-Byram Drought Index of soil dryness is the most common. But complex fuels with leaves, twigs, grass etc make the predictive models often inadequate for fine fuels. The most common technique in Victorian forests until recently was the trusty Speedy Moisture Meter. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s (I think). Fuel was first ground using a Spong mincer, often attached to the bullbar of a vehicle, and a small sample placed into the Speedy together with a measure of calcium carbide and then sealed. A chemical reaction created gas pressure which was read on the external dial. There were important techniques with cleaning, mincing and using the chemicals with the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. But in about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance. Wiltronics is an Australian owned company operating from Ballarat. The final result was a kit that was portable, accurate and could reliably measure fuel moisture contents between 3% and 200%. Although expensive, it is now widely used by fire agencies around the world which has virtually relegated the Speedy to the back cupboard.Prototype Fuel moisture meterT-H Fine Fuel Meterforests commission victoria (fcv), bushfire, forest measurement

Representative samples of fuel such as bark, leaves, twigs etc were minced and the moisture measured The availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme. During the afternoon of the Ash Wednesday bushfires on 16 February 1983 fuel moisture contents were recorded at Stawell as low as 2.7%. Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out.
