Common Opal is a mineraloid that is non crystallising and is classed as an amorphous silicate, the chemical composition for Opal is SiO2 nH2O. Opals can develop in weathered sedimentary rock typical in arid regions where limited water enters small gaps in the rock, and the silicate is hydrated. Common opals, unlike precious opals, do not exhibit ‘play of colour’ in which the colour appears to change depending on the angle of view. While precious opals are highly valuable and cut as gemstones for jewellery, common opals can be cut into inexpensive gemstones and are also mined for various uses including as ingredients in ceramics, insulation, fillers, and abrasives. The source of this common opal specimen is unknown, but common opals are found around the world, notable deposits are found in Queensland, South Australia, New South Wales, Peru, Kenya, Nevada, Oregon, and Mexico. This common opal specimen is of historic and scientific significance due to its donation in 1868 as part of the Geological Survey of Victoria and as a typical example of uncut common opal. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A palm-sized amorphous (non-crystallising) hydrated silicate mineraloid specimen in shades of brown, orange, and white.Existing label: Common Opal / Locality unknowngeological specimen, geology, geology collection, burke museum, beechworth, common opal, opal, mineraloid, amorphous silicates, hydrated silicate

Dolomite is a mineral, calcium magnesium carbonate, with the chemical formula CaMg(CO3)2. It is a principle component of various rock types sometimes also referred to as dolomite, including dolostone, dolomitic marble and dolomitic limestone (according to the composition of each type). Dolomite rock is found in sedimentary basins throughout the world, comprising approximately 2% of the Earth's crust. It is formed when lime mud or limestone encounters groundwater containing magnesium. Dolomite can contain elements such as lead, zinc and copper. Dolomite and limestone are used in various construction, landscaping and agricultural processes. This specimen was donated to the Burke Museum in 1868 by Alfred Selwyn as part of the Geological Survey of Victoria. It was donated to the Museum in 1868. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole. Dolomite and limestone are mined at several locations in Victoria, including sites in the North-East of the state in Bindi and Limestone Creek. There are notable dolomite deposits in most Australian states. The dolomitised form of the mineral tends to come from older limestone deposits, formed during the palaeozoic era in marine settings, so this specimen may have come from a deposit located along a coastline in Victoria or another state. The specimen is significant as an example of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Kaolin is also known as china clay. This specimen came from Dunolly, Victoria and was donated to the Museum in 1868 as part of the Geological Survey of Victoria. This survey helped map and study the geology of Victoria. In Victoria, Kaolin is particularly used as a filler and coating material in paper manufacture. It can also be used in paints, ceramics, rubbers and plastics. There are many kaolin deposits in Victoria but many of these have been mined out and there is not much Kaolin left. Rocks that have a high amount of Kaolinite and it can be formed through the decomposition of other materials. There are two types of Kaolin; hard and soft kaolin. Soft kaolin's are coarse but have a soapy texture. It can also break easily. The hard kaolins have an earthly texture and are finer grained. This means that they are harder to break, unlike the soft kaolin. Hard kaolin's are formed by flocculation in salt water, a process that in basic terms, bonds particles together. Kaolin is a common material in Victoria and that is why it is significant. While this specimen was mined in Dunolly, Victoria Kaolin can also be found Pittong, Pakenham, Bulla, Hallam and Ballarat as well as many other places throughout Victoria. This specimen represents the presence of Kaolin deposits in this region of Australia. It is also significant because Kaolin has many uses and is largely beneficial to many manufacturing processes in Victoria. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Actinolite is usually found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks. It also occurs as a product of the metamorphism of magnesium-rich limestones. Pyrite is usually found with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well coal beds, and as a replacement mineral in fossils. Actinolite is an amphibole silicate mineral. It is named after the Greek word "aktinos" meaning “ray” in allusion to the mineral's fibrous nature. Fibrous actinolite is a type of asbestos and was once mined along Jones Creek at Gundagai, New South Wales. Pyrite or "Fool's Gold" is the most common sulfide mineral. It is named after the Greek "pyr" meaning "fire" because it can be used to create sparks needed for a fire if struck against metal or a hard surface. Due to its gold colour, pyrite can be mistaken for gold and often forms alongside it, causing small amounts of gold to be present in rocks containing pyrite. Most importantly, pyrite is an ore of gold. Pyrite is sometimes used as a gemstone but is not great for jewellery as it easily tarnishes. In some fossils of ammonites – shelled cephalopods that died ~66 million years ago – pyrite also replaces the shell. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Malachite is a water soluble, crystalline, triphenyl methylene chloride salt. It has a close relationship to copper because it is common for Malachite and copper to come from the same ore. Malachite often has shades of green, making it also known as Malachite Green. As a result of it's colour, it is known for being a dye and has been used in the dye industry, the textile industry and in medical fields. Cobar in New South Wales is well known for it's mining. This is because of the number of important deposits present in the area and include three important mining belts where most of the materials are found. These are the 'Cobar belt', the 'Canbelego belt' and the 'Girilambone belt'. The 'Cobar belt' runs underneath the main town. Copper was first discovered in Cobar in 1869 and since then, many deposits of other materials have been found, including Malachite.This specimen is significant because it comes from Cobar, NSW and represents the many deposits of materials found there. Cobar has a long history of mining and is a source of Australia's copper minerals. Malachite is often found in copper deposits meaning that it is representative of Cobar's copper production. Malachite is known for it's vivid green colour and as a result, has many uses, such as meaning used as a dye. This makes it a valuable material and highly significant. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

This particular specimen is found in Wolgan Valley, New South Wales. It could be linked to the abandoned oil shale mining sites in Wolgan Valley such as Newnes. Newnes was an industrial complex operational in the early 20th century is now partly surrounded by Wollemi National Park. It produced motor spirit, kerosene, and gas oil. Newnes's Torbanite oil shale rock contained around 350 litres of oil shale per tonne. The Torbanite was mined by the Commonwealth Oil Corporation Ltd. Oil shale is a sedimentary rock and also a form of fossil fuel. It is often formed millions of years ago and usually contain fossilised remains of plants and/or animals. Oil shale is rich in kerogen that releases hydrocarbon when heated. These hydrocarbon can be used as an alternative petroleum or natural gas. The oil-shale rock was converted into oil by "destructive distillation"; the rock being heated until it broke down to form an oily vapour and an ash residue. Oil bearing shale is one of Australia's national assets. There are many oil companies established in Australia. It reflects Australia's rich natural resources as well as connection to the Australia's engineering and oil industry. The booming oil shale extraction businesses can be traced as far back as 1920s. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Amazonite is classed as a Tectosilicate and is part of the Feldspar group of minerals. Amazonite forms in a triclinic crystal structure and its chemical formula is K(AlSi3O8). In appearance, Amazonite can range from shades of green to green blue to blue, and often with white streaks or veining. The greenish colour is believed to come from the small amount of lead contained in its composition. Amazonite is named after the Amazon River due to its colour and similarities to another rock found along the riverbanks, although Amazonite is not actually found at or near the Amazon. Although less commonly used in jewellery today, Amazonite has been mined and used by humans for thousands of years and Amazonite jewellery from at least 2000BCE have been discovered in North Africa. Amazonite is found in many locations around the world including Brazil, Peru, Ethiopia, Canada, Russia, Mozambique, Myanmar, Pakistan, China, Madagascar, and the United States of America. This specimen most probably comes from the U.S.A., Amazonite is found in several US states particularly in Colorado, Virginia, Pennsylvania. This specimen is of both scientific and historic significance as a striking blue green example of Amazonite mined prior to 1868 in the United States of America, most likely from Colorado, Virginia, or Pennsylvania. These three states are all locations of significant Amazonite deposits. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Malachite is a green copper carbonate hydroxide mineral and was one of the first ores used to make copper metal. Malachite has been utilised as a gemstone and sculptural material in the past as its distinctive green color does not fade when exposed to light or after long periods of time. Malachite is formed at shallow depths in the ground, in the oxidizing zone above copper deposits. The material has also been used as a pigment for painting throughout history. Malachite is considered a rare gemstone in that the original deposits for the stones have been depleted leaving behind very few sources. In addition, the use of Malachite as gemstones and sculptural materials remains just as popular today as they were throughout history. It is quite common to cut the stone into beads for jewellery. The fact that Malachite has such a rich colour and one that does not fade with time or when exposed to light makes it particularly rare. Although there is no indication available of the locality from which the specimen was sourced, it is likely that the specimen was collected either in South Australia in the vicinity of the Burra Burra mines or in Victoria as part of programs of geological surveying undertaken in the Nineteenth and Twentieth centuries. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Galena occurs in a range of deposit contexts, often in metalliferous veins, such as Broken Hill, Australia; Coeur d’Alene, Idaho, United States.; Clausthal Zellerfeld, Germany; and Cornwall, England. Large deposits also replace limestone, dolomite, or occasionally organic matter, or have a contact-metamorphic origin. Galena is additionally found in cavities, brecciated (fractured) zones in limestone and chert, and in coal beds. This specimen was recovered from Broken Hill NSW and is 60% lead with 8-12 oz/silver to the ton.Galena or 'lead glance' is a grey lead sulfide and the chief ore mineral of lead. It forms isometric crystals in which the ionic lattice is similar to sodium chloride. Galena is brittle and easily weathers to secondary lead minerals, with the upper part of mineral deposits often containing cerussite, anglesite, and pyromorphite. It usually contains silver, which is mined along with its lead content. Other commercially important minerals that form in close association with galena are antimony, copper, and zinc. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Anthracite typically occurs in geologically deformed areas due to extreme heating – with temperatures ranging from 170 to 250 °C – caused by igneous intrusions or high geothermal gradients. It is most commonly found in northeastern Pennsylvania in the United States; however, smaller amounts are also found in Australia, China, eastern Ukraine, South Africa, western Canada, and other countries. This specimen was recovered from Tasmania and is 85-95% carbon.Anthracite is the mineral name for hard coal and is the least plentiful of all coal types. It is clean to the touch and, when polished, is used for decorative purposes. Before natural gas and electricity, anthracite was used for domestic heating as it produces little dust, burns slowly, and gives off a minor amount of smoke. However, it is also limited in abundance and expensive. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

It is not known where this opal originated. Common Opal is formed from silica-rich water entering the earths crust and hardening into a gel of water and silica-spheres, layered through the specimen. Common opal differs from precious opal in colouration and appearance, with precious opal including more colours, and having a translucent or glossy appearance, where common opal shows less colour and is typically opaque. It scores high on the Mohs hardness scale, and is common throughout the world, especially in Australia, where it is far more prevalent than the highly-prized precious opal. Australia is also the highest producer of opals in the modern world. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Selwynite is a fine-grained, compact green rock made primarily of chromian muscovite (fuchsite) and diaspore. Corundum and fuchsite can occur together in the form of massive aggregates or nodules. Often, copper carbonates are found as earthy films or tiny crystals in joint planes. The mineral name honours the late A. R. C. Selwyn, founding Director of the Geological Survey of Victoria. The particular specimen, a mottled green stone suitable for carving was recovered and found in Heathcote, Victoria, Australia. The rarity and qualities of this mineral attracted commercial mining, which was not successful, but traces of the mine shafts still exist today, and it is still highly valued by mineral collectors.Selwynit is considered to be one of the rare forms of rock because it is composed of phosphate minerals containing zirconium. This is an extremely rare combination found in nature. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

A granular metamorphic rock, marble is derived from limestone or dolomite and composed of calcite or dolomite interlocking grains. Heat and pressure from overlying sediments form it from limestone buried deep in Earth's crust. Graphite, pyrite, quartz, mica, and iron oxides can affect rock texture and colour. This specimen was found in Carrara, Italy. Carrara marble is the most common marble found in Italy, and it gets its name from the region where it is located. The marble was also called Luna marble and was used as a decorative element in buildings and sculptures. It has been quarried since Roman times in the Lunigiana, the northernmost tip of Tuscany, just outside the city of Carrara in the province of Massa and Carrara.Marble is one of the most popular and expensive rocks used in sculpture, architecture, interior decorations, statues, table tops, and novelties. It is available in various colors and textures depending on the chemical composition. The strength of the rock and its ability to hold finer details have made it a favorite among designers. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Bituminous coal is the most common type of coal, abundantly found in ancient coal deposits which can be dated back millions of years. Often referred to as soft or black coal, this specimen exhibits a high carbon content, ranging from 76-86%. It also holds a relatively high energy density (27 MJ/kg) meaning that it releases significant amounts of energy when burned. Bituminous coal is most commonly used for electricity generation, as well as in the production of steel. This particular piece of coal was collected as part of the Geological Survey of Victoria in the nineteenth century. It originates from Cape Paterson, a seaside village located in South Gippsland, Victoria (located on Bunurong Country). The discovery of bituminous coal in this locality was first made in 1826 by explorer William Hovell. More discoveries were gradually made over the following decades and in 1859 the Victorian Coal Company commenced the first active coal mining operations in the state by sinking a number of shafts and bores near the area of Cape Paterson. Evidence of this coal-focused past can be found today at the State Coal Mine Museum in the nearby town of Wonthaggi. This specimen is significant as it was collected from the locality of Cape Paterson in Victoria, an area that has since become historically instrumental in the mining of coal and other substances in the state of Victoria. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Malachite is a copper carbonate hydroxide mineral. It has a chemical composition of Cu2(CO3)(OH)2. It often forms within limestone where a subsurface chemical environment favourable for the formation of carbonate minerals can occur. It is a substance that can be found in many different parts of the world including: Australia, USA, Russia and the Democratic Republic of Congo. Malachite has historically been used to produce copper, with mining of the mineral dating back over a period of four thousand years. Due to its beautiful green colourations, it is also commonly used for aesthetic purposes such as in the production of sculptures and jewellery. This particular specimen was collected from the town of Burra, South Australia as part of a geological survey undertaken during the nineteenth century. The locality (located on Ngadjuri Country) has a long history of mining, particularly in copper mining, as the area is rich in copper deposits. The first significant discovery of this was made in Burra (Burra Burra Mine) in 1845 and, at the time, the mine was the largest and richest of its kind in the world, producing nearly five percent of the total world copper output. This specimen is significant as it is considered to be a rare gemstone, as many of the original deposits for the stones are significantly depleted, leaving behind very few sources. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Laterite refers to both a rock and a soil type that is rich in clay, as well as Iron and Aluminium. It is created during a process that is called laterization, where high heat and seasonal heavy rainfall cause there to be wet and dry periods, which over time hardens the soil into rock. Because of this, most laterite is formed between tropics of Cancer and Capricorn. The iron oxide in laterite is what gives it it’s orange-red colouring. The largest religious complex in the world, Angkor Wat in Cambodia, is partially constructed of laterite, particularly its foundations, as laterite is porous and allows rainwater to drain. This specimen of laterite was collected from the Democratic Republic of Congo while it was colonised by Belgium in the 19th century. Laterite forms in many parts of the world, particularly between the tropics. It is used both for ore and as a building material, and comparing specimens from different parts of the world allows us to document the different compositions that this mineral can have when formed at different locations. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Montmorillonite is a type of clay composed of aluminium silicate that forms very small particles that are not well-bonded to one another. This is why it is so soft. When in the presence of water, all types of clay swell. Montmorillonite swells even more than most types of clay, which is why it is often chosen over other types of clay in its practical uses. Montmorillonite has many different practical uses, including in the mining industry, as a soil additive, as a sealant, as a desiccant to draw water out of the air, to clean ponds, to make kitty litter and in cosmetics. Montmorillonite is a common mineral and, despite being named after Montmorillon, France, can be found all over the world, including many deposits in Australia. It is not known where this particular specimen originates from. Montmorillonite is an economically and socially significant material with a wide variety of uses. Having samples of common and important minerals allows collections, like the Burke Museum, to have a more complete view of the land on which they are located, and therefore a more complete view of heritage. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

This specimen is Cassiterite in Quartz. Cassiterite is a tin oxide metal that forms in thin crystals which can have a beautiful lustre. Quartz is made of silicon dioxide, also known as silica, and is one of the most common minerals on earth. Cassiterite has been a fundamental source of tin ore for humans throughout history, including today. Tin is an important metal that has a wide variety of human uses in different areas, from dying fabric, to making mirrors, and their most well-known use ‘tin’ cans. Tin cans are primarily made of steel and are coated with tin in order to take advantage of tin’s property of being non-corroding. This is a massive step in the history of food preservation. Tinned food first reached Australia in 1815 with early settlers, and it began to be manufactured here in the 1840s. It was incredibly popular, and was a highly exported product, which would be a contributing factor to the ‘tin mining boom’ of the early 1880s. This specimen was collected at Jingellic, New South Wales, in about 1852. Although the Goldfields of the 1800s are much more well-known, tin mines existed alongside the gold mines which began in the mid 19th century and extended almost one hundred years, to the mid 20th century. Specimens like this would have been used as evidence to justify tin mining operations in the region as an investment. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. The Geological Survey of Victoria was headed by British geologist, Alfred Richard Cecil Selwyn (1824-1902), who was responsible for issuing over 60 geological maps during his 17 years as director. These maps were all hand-drawn and coloured and became the benchmark for accuracy for geological mapping. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. A fist-sized solid geological specimen made on one half of tin oxide, which is dark grey, and on the other side of silica, which is brown and cream.burke museum, beechworth, geological, geological specimen

There are 17 opal fields in Australia. This opal bearing stone was found in Lightning Ridge, NSW over what is known as the Great Australian Basin. This basin was formed and covers an area of 1.7 million square kilometers in eastern Australia in the Cretaceous period. This basin used to contain an inland sea, which provided an environment where silcrete eventually formed when water levels changed. This eventually seeped into other structures, and eventually hardened and formed opal. Lightning Ridge has a population of around 2000 people, with about 80 000 visitors every year. It is a historic mining town, and is known for its deposits of a rare black opal. Mining started in the area in the late 1800s, early 1900s when the black opal was discovered. This opal-bearing stone is of social and historical significance. It is from Lightning Ridge, which is well-known for being a large producer of opal stones, most famously black opal. The history of the period dates back to 140 million years, with the discovery of black opal in the early 1900s causing interest in the area.

It is made up of andalusite. Andalusite is a rock-forming mineral, sometimes found in granite or schist. It is often used to make glass, ceramic products, chemicals, and heat-resistant bricks as it can withstand high temperatures without changing. The chiastolite contains particles of graphite, which arranges in geometric patterns. When crystal growth occurs in the rock, the granite particles concentrate at crystal interfaces and can result in cross shapes. These ‘cross stones’ have been valued and used for their spiritual or religious meaning and used as charms, gems, or amulets. Chiastolite was first discovered in 1754, seen in a description in a published book by a palaeontologist, Franciscan priest, and Spanish author, Jose Torrubia. Deposits have been found in Australia, France, the USA, Chile, Canada, Spain, Brazil, Sri Lanka, and Russia. Deposits have been found in Western Australia and South Australia. This particular specimen was found in Bimbowrie, South Australia. Other chiastolite specimens have been found in Bimbowrie, along with jasper, quartz, and aventurine in the form of rolled pebbles or schist. This chiastolite specimen is socially and historically significant. It is a very rare sort of andalusite mineral. It is from one of only two locations where it is regularly found in Australia. The carbon cross has made it an important religious symbol in the past. Its ability to withstand high temperatures has made it a common ingredient in heat-resistant bricks and ceramics today.

This large, leather bound journal was made for the Public Library and Burke Museum in Beechworth by book manufacturer, William Detmold in 1875. It was commissioned by the President of the Library and Burke Museum committee, Dr Antoine Mousse, for the purpose of cataloguing all the items in the collection. The cataloguer was the curator at that time, William Morton, whose hand-writing appears in the journal today. When William Morton first started recording in this journal in 1875, there were already a number of existing items in the institution. The Public Library and Burke Museum in Beechworth had actually been operating since the 1850s; first as a Young Men’s Association in 1856, then as Beechworth Athenaeum in 1858, then as the Beechworth Public Library in 1860. Then in 1861 when news of the death of Beechworth’s former police superintended, Robert O’Hara Burke, reached the town, it was agreed that the Public Library would also become a museum to tribute his legacy, renaming it as the ‘Public Library and Robert O’Hara Burke Memorial Museum, Beechworth’. Many of the items from the early institutions would have been used to form the nucleus of this new organisation. Plus, the additional items that were either collected or donated to develop it into a museum. The catalogue is extensive. There are exactly 461 pages of recorded items, each page detailing the various collections the museum acquired in the late 19th century. Collections recorded in this catalogue include a large collection of geological specimens, that were given to the museum in 1868 by the Geological Survey Department of Victoria. A large collection of taxidermy mounts, that were given to the museum as skins by the Museum of Australia in 1865. An extensive collection of Aboriginal artefacts that were purchased from amateur anthropologist R. E . Johns in 1868. As well as artworks, charts, photographs, machinery, maps etc., all of which have been held in the museum since. This catalogue also details the governance and management of the organisation. There were originally 30 rules that governed the actions for the management committee and, while anyone could read in the free library, only subscribers could borrow two books and one periodical. At first, subscriptions rates were 7/6 a quarter. This was later changed to £1 per annum, paid quarterly in advance. This was a considerable amount; 7/6 per quarter meant that the annual fee was £1.10. This was equivalent to about £650.00 or about $1,182.00AUD today, while the reduced subscription fee of £1 a year was the equivalent to £450.00 or about $818.00AUD today. Membership of the athenaeum would have been the reserve of the town's notable citizens. The vale of the catalogue lies not only in its historical connect with the establishment of the Athenaeum and the current museum, but also in its record of the names and positions of all members of the institution's committees of management from 1875-1876. This is a unique object that contains important records for a notable country town. Large brown leather bound book made in 1875 for the Beechworth library and museum by William Detmond.
