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. 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 solid tennis-ball sized chunk of aluminium silicate clay.

This hollow core bit has hard cutting inserts for drilling into rock. It was used to drill and recover 50mm diameter (most common size) rock cores. The rock cores were assessed by geologists and engineers to provide information for design of structures such as tunnels, dams and underground power stations (eg. McKay Creek Power Station, West Kiewa Power Station). This type of bit was also used where damage to the surrounding rock had to be minimised. The Diamond Drill Bit,used in the early 1900's, when it was primarily used as a method of sampling rock for ore deposits and oil exploration resulting in a "coring" of rock. The use of "coring" to obtained samples for the SEC Kiewa Hydro Electricity Scheme(1920's onward) was to analyse the core to obtain temperature and rainfall patterns shown by the levels of layered solidified soil(rock). This diamond drill would have been used in the early 1900's to provide a sub strata map of temperature and water patterns (over an long period of time). This was a pre requisite to any decisions about the viability of the region to provide the water needed for a successful hydro electricity scheme.This diamond drill for core sampling was at the forefront of the analysis whether to construct a hydro electrical facility in the Kiewa Valley and the adjoining alpine region. The rock core samples produced were assessed by geologists and structural engineers. It was only after extensive core drilling covering the region that solid scientific evidence could be provided to start the "SEC Vic Hydro Electricity Scheme" within its current boundaries.This "diamond" drill bit has eight "teeth" at its cutting edge. The drill creates an 55mm hole in extremely hard rock material to obtain 50mm core samples.. Three quarters down the shank it has thread screw channels to attach the bit to the drill pipe. The coring pipe attaches via screwing it onto this bit. Core samples are the main objective of this tool.alternate energy supplies, alpine feasibility studies temperature, rainfall, sec, kiewa hydro electric scheme, electricity

"The hated Protector" tells for the first time the real story behind the extraordinary experiences of Charles Sievwright, Assistant Aboriginal Protector from 1839-42 in what was then part of the British colony of New South Wales, but is now the Western District of the Australian state of Victoria. Sievwright, an Edinburgh-born former British army officer, lived in the bush with his young family as he tried to save the Aborigines of the District from extinction. In doing so, he would isolate himself from the rest of his fellow whites. The hated Protector tells of this process. The book should appeal to anyone interested in British colonial and Australian history, particularly in the years of first contact between British settlers and the Aborigines. More broadly, it should also appeal to anyone interested a story of one man's battle against overwhelming odds, where the price of failure was numerous deaths. It is a story of hatred, prejudice, courage, determination, and hope. In telling Sievwright's story, Lindsey Arkley draws largely on original archival material, including official reports, journals and letters, found in Melbourne, Sydney, Hobart, Edinburgh and London. Most has never before been published. The archival material is supplemented by contemporary newspaper accounts, and some oral history. Full notes are given to all sources, and the book is indexed and lavishly illustrated with drawings by Joan Bognuda, as well as about 80 paintings and samples of documents. Contents: 1.

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. 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. 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
