The law court buildings on the corner of Russell and La Trobe Streets (Melbourne) were later to house the Supreme Court of Victoria. The law courts were built in 1842. The inscription by Dorothy Rogers [sic] incorrectly describes the builders as Swanson Bros., who instead were the builders of the later Magistrates Court on the same site. Matchbox containing architectural fragments from the old law courts [Supreme Court] in Russell Street. The matchbox has a label on the front and more detailed information included in a note inside the box. The item is believed to have belonged to the historian Dorothy Rogers.Exterior "Chips from the old law courts Russell St." Inside: "Court House built by Swanson Bros in 1842 of Moorabool Stone & opened 1st time [sic] in 1843.

This wood was cut from a 6000 year old Murray River red gum retrieved from the Wodonga gravel pits on the flood plain. The Museum of Victoria displayed this wood in the base on which Phar Lap stands. It was made by Kevin Barton of the Kiewa Valley to the order of Dr. James Bowler, the geologist who dated the ancient gravel pit red gums. This specimen is historically significant and unique in local, national, and international context. It is unique, of scientific and research value, and exceptionally rare due to its age. 6000 year old wood from a Murray River red gum. geology, geological, murray river, red gym, murray river red gum, kiewa, wodonga, history

Although it is not known where these specimens were collected, 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. Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. The term carnelian primarily refers to the reddish shading of the stone; whether the stone is termed an agate or chalcedony type is often influenced by the degree of colour banding the specimen shows. The specimens are significant as examples 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.Three small geological specimens that appear visually consistent with images of rough or unpolished Carnelian Agate or Chalcedony. geological specimen, geology, geology collection, burke museum, beechworth, indigo shire, north-east victoria, gemstones, agate, carnelian

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.

Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. Although relatively common and semi-precious, agate has been prized since at least 1450 BC - an intricately carved agate seal was found in the 2015 excavation of a grave belonging to a Mycenaeum priest or warrior near Pylos in Greece. Agate is also used in jewellery and other decorative or ritual purposes due to its often striking appearance. Quartz is found all over Australia, including Beechworth in Victoria. It is formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. It can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. The colour of quartz can vary. These specimens were collected in Victoria in the vicinity of the Burke Museum.

According to the 1912 Department of Mines Bulletin of the Geological Survey of Victoria, basalt covers a considerable portion of the Macedon area including Mount Macedon. Basalt is the most common form of rock underlying the earth's surface and is found in three kinds of rock forming environments: ocean divergent boundaries, oceanic hotspots, and mantle plumes and hotspots beneath continents.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.

Hyalite is a colourless variety of opal. It occurs as globular and botryoidal masses and irregular crusts in volcanic and pegmatite environments where the silica deposits from the gas phase. Basalt is dark in colour, fine-grained igneous rock composed of plagioclase and pyroxene minerals. It is commonly formed as an extrusive rock, such as lava flow. It is one of the most common forms of rock underlying the earth's surface.burke museum, geological specimen, department of mines, geological survey of victoria, basalt, mount macedon, beechworth
