72-753: Billiluna Station is a pastoral lease that operates as a cattle station in Western Australia . It is located approximately 70 kilometres (43 mi) north of Balgo and 150 km (93 mi) south of Halls Creek in the Kimberley region of Western Australia. The name of the station is taken from a pool in Sturt Creek found and mentioned by Alfred Canning when he mapped out the Canning Stock Route in 1907. The Billiluna Pastoral Company Limited, previously known as Sturt Creek Pastoral Company Limited,

144-447: A bit in a borehole . Drilled wells are usually cased with a factory-made pipe composed of steel or plastic. Drilled wells can access water at much greater depths than dug wells. Two broad classes of well are shallow or unconfined wells completed within the uppermost saturated aquifer at that location, and deep or confined wells, sunk through an impermeable stratum into an aquifer beneath. A collector well can be constructed adjacent to

216-593: A better future in the beef cattle industry. The North Australian Pastoral Company Pty Limited (NAPCO) is now one of Australia's largest beef cattle producers, with a herd of over 180,000 cattle and fourteen cattle stations in Queensland and the Northern Territory. The Australian Agricultural Company (AA Co) manages a cattle herd of more than 585,000 head. Heytesbury Beef Pty Ltd owns and manages over two hundred thousand head of cattle across eight stations spanning

288-456: A caisson vertically below the top of the aquifer and then advancing lateral collectors out of the caisson and beneath the surface water body. Pumping from within the caisson induces infiltration of water from the surface water body into the aquifer, where it is collected by the collector well laterals and conveyed into the caisson where it can be pumped to the ground surface. Two additional broad classes of well types may be distinguished, based on

360-589: A chain of cattle stations along the sources of water, from the Gulf of Carpentaria , into South Australia to be within easy droving distance of the Adelaide markets. Aborigines have long played a big part in the cattle industry where they were competent stockmen on the cattle stations of the north. In 1950 it was legislated that the Aboriginal workers were now to be paid cash wages. Many cattle stations were established along

432-470: A circulation fluid to displace cuttings and cool bits during the drilling. Another form of rotary-style drilling, termed mud rotary , makes use of a specially made mud, or drilling fluid, which is constantly being altered during the drill so that it can consistently create enough hydraulic pressure to hold the side walls of the bore hole open, regardless of the presence of a casing in the well. Typically, boreholes drilled into solid rock are not cased until after

504-435: A confined space, it displaces oxygen, reducing oxygen concentration to a level low enough to pose a threat to humans and other aerobic organisms but still high enough for a risk of spontaneous or externally caused explosion. This potential for explosion is what poses such a danger in regards to the drilling and placement of water wells. Low levels of methane in drinking water are not considered toxic. When methane seeps into

576-676: A divination text of the Western Zhou dynasty (1046 -771 BC), contains an entry describing how the ancient Chinese maintained their wells and protected their sources of water. A well excavated at the Hemedu excavation site was believed to have been built during the neolithic era. The well was cased by four rows of logs with a square frame attached to them at the top of the well. 60 additional tile wells southwest of Beijing are also believed to have been built around 600 BC for drinking and irrigation. In Egypt , shadoofs and sakias are used. The sakia

648-541: A dozen Aboriginal people from the Kutjungka region were killed by police in the Sturt Creek massacre in a punitive expedition led by Constable J.J.Cooney in response to the attacks on Condren and O'Sullivan. The property was placed on the market in 1925 as part of a deceased estate. At this time it occupied an area of 897,000 acres (3,630 km) and had two wells in addition to good surface water sources. Buildings included

720-550: A drilling action. Unlike rotary drilling, cable tool drilling requires the drilling action to be stopped so that the bore hole can be bailed or emptied of drilled cuttings. Cable tool drilling rigs are rare as they tend to be 10x slower to drill through materials compared to similar diameter rotary air or rotary mud equipped rigs. Drilled wells are usually cased with a factory-made pipe, typically steel (in air rotary or cable tool drilling) or plastic / PVC (in mud rotary wells, also present in wells drilled into solid rock). The casing

792-510: A freshwater lake or stream with water percolating through the intervening material. The site of a well can be selected by a hydrogeologist , or groundwater surveyor. Water may be pumped or hand drawn. Impurities from the surface can easily reach shallow sources and contamination of the supply by pathogens or chemical contaminants needs to be avoided. Well water typically contains more minerals in solution than surface water and may require treatment before being potable. Soil salination can occur as

864-743: A group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. PFAS are a group of "forever chemicals" that spread very quickly and very far in ground water polluting it permanently. Water wells near certain airports where any form fire fighting or training activities occurred up to 2010 are likely to be contaminated by PFAS. A study concluded that of ~39 million groundwater wells 6-20% are at high risk of running dry if local groundwater levels decline by less than five meters, or – as with many areas and possibly more than half of major aquifers – continue to decline. Springs and wells have had cultural significance since prehistoric times, leading to

936-430: A pump. The water often comes from an aquifer or groundwater, and can be easily deepened, which may be necessary if the ground water level drops, by telescoping the lining further down into the aquifer. The yield of existing hand dug wells may be improved by deepening or introducing vertical tunnels or perforated pipes. Drawbacks to hand-dug wells are numerous. It can be impractical to hand dig wells in areas where hard rock

1008-433: A screening device, filter pack, slotted casing, or open bore hole is left to allow the flow of water into the well. Constructed screens are typically used in unconsolidated formations (sands, gravels, etc.), allowing water and a percentage of the formation to pass through the screen. Allowing some material to pass through creates a large area filter out of the rest of the formation, as the amount of material present to pass into

1080-406: A segmented steel drilling string, typically made up of 3m (10ft), 6 m (20 ft) to 8m (26ft) sections of steel tubing that are threaded together, with a bit or other drilling device at the bottom end. Some rotary drilling machines are designed to install (by driving or drilling) a steel casing into the well in conjunction with the drilling of the actual bore hole. Air and/or water is used as

1152-564: A two-room house, beef house and harness house. Four sets of yards had also been built along with a fenced horse paddock. It was stocked with 2,500 head of cattle and about 40 horses. An Armstrong Siddeley was the first car to be driven to Billiluna as part of an 1,100-mile (1,770 km) trip through the Kimberley. The vehicle was landed at Derby and driven to the shores of Lake Gregory at Billiluna via Sturt Creek Station over 87 miles (140 km) of trackless country. The Canning Stock Route

1224-420: A variety of tools including electro-seismic surveying, any available information from nearby wells, geologic maps, and sometimes geophysical imaging . These professionals provide advice that is almost as accurate a driller who has experience and knowledge of nearby wells/bores and the most suitable drilling technique based on the expected target depth. Shallow pumping wells can often supply drinking water at

1296-567: A very important source of potable water in some rural developing areas, where they are routinely dug and used today. Their indispensability has produced a number of literary references, literal and figurative, including the reference to the incident of Jesus meeting a woman at Jacob 's well ( John 4:6) in the Bible and the " Ding Dong Bell " nursery rhyme about a cat in a well. Hand-dug wells are excavations with diameters large enough to accommodate one or more people with shovels digging down to below

1368-608: A very low cost. However, impurities from the surface easily reach shallow sources, which leads to a greater risk of contamination for these wells compared to deeper wells. Contaminated wells can lead to the spread of various waterborne diseases . Dug and driven wells are relatively easy to contaminate; for instance, most dug wells are unreliable in the majority of the United States. Some research has found that, in cold regions, changes in river flow and flooding caused by extreme rainfall or snowmelt can degrade well water quality. Most of

1440-648: A water supply, it is commonly referred to as "methane migration". This can be caused by old natural gas wells near water well systems becoming abandoned and no longer monitored. Lately, however, the described wells/pumps are no longer very efficient and can be replaced by either handpumps or treadle pumps . Another alternative is the use of self-dug wells, electrical deep-well pumps (for higher depths). Appropriate technology organizations as Practical Action are now supplying information on how to build/set-up ( DIY ) handpumps and treadle pumps in practice. Per- and polyfluoroalkyl substances ( PFAS or PFASs ) are

1512-693: Is a common problem with groundwater. Nitrates from sewage , sewage sludge or fertilizer are a particular problem for babies and young children. Pollutant chemicals include pesticides and volatile organic compounds from gasoline , dry-cleaning , the fuel additive methyl tert-butyl ether (MTBE), and perchlorate from rocket fuel, airbag inflators, and other artificial and natural sources. Several minerals are also contaminants, including lead leached from brass fittings or old lead pipes, chromium VI from electroplating and other sources, naturally occurring arsenic , radon , and uranium —all of which can cause cancer—and naturally occurring fluoride , which

1584-399: Is caused when the water table of the soil drops over time and salt begins to accumulate. In turn, the increased amount of salt begins to dry the soil out. The increased level of salt in the soil can result in the degradation of soil and can be very harmful to vegetation. Methane , an asphyxiant, is a chemical compound that is the main component of natural gas. When methane is introduced into

1656-437: Is constructed by welding, either chemically or thermally, segments of casing together. If the casing is installed during the drilling, most drills will drive the casing into the ground as the bore hole advances, while some newer machines will actually allow for the casing to be rotated and drilled into the formation in a similar manner as the bit advancing just below. PVC or plastic is typically solvent welded and then lowered into

1728-455: Is desirable in low quantities to prevent tooth decay , but can cause dental fluorosis in higher concentrations. Some chemicals are commonly present in water wells at levels that are not toxic, but can cause other problems. Calcium and magnesium cause what is known as hard water , which can precipitate and clog pipes or burn out water heaters. Iron and manganese can appear as dark flecks that stain clothing and plumbing, and can promote

1800-473: Is drilled to a predetermined depth or to a confining formation (clay or bedrock, for example), and then a smaller hole for the well is completed from that point forward. The well is typically cased from the surface down into the smaller hole with a casing that is the same diameter as that hole. The annular space between the large bore hole and the smaller casing is filled with bentonite clay , concrete, or other sealant material. This creates an impermeable seal from

1872-649: Is much more efficient, as it can bring up water from a depth of 10 metres (versus the 3 metres of the shadoof). The sakia is the Egyptian version of the noria . Some of the world's oldest known wells, located in Cyprus, date to 7000–8,500 BC. Two wells from the Neolithic period, around 6500 BC, have been discovered in Israel. One is in Atlit, on the northern coast of Israel, and the other is in

1944-577: Is not connected, electricity is typically provided by a generator, although solar electricity systems have become increasingly common. Children were originally educated by correspondence lessons , often supervised by a governess , and via the School of the Air , but many children in remote areas went to boarding school for their secondary education. The Royal Flying Doctor Service is available to remote stations in outback Australia. Historically, an outstation

2016-600: Is present, and they can be time-consuming to dig and line even in favourable areas. Because they exploit shallow aquifers, the well may be susceptible to yield fluctuations and possible contamination from surface water, including sewage. Hand dug well construction generally requires the use of a well trained construction team, and the capital investment for equipment such as concrete ring moulds, heavy lifting equipment, well shaft formwork, motorized de-watering pumps, and fuel can be large for people in developing countries. Construction of hand dug wells can be dangerous due to collapse of

2088-477: Is simply hammered into the ground, usually with a tripod and driver , with pipe sections added as needed. A driver is a weighted pipe that slides over the pipe being driven and is repeatedly dropped on it. When groundwater is encountered, the well is washed of sediment and a pump installed. Drilled wells are constructed using various types of drilling machines, such as top-head rotary, table rotary, or cable tool, which all use drilling stems that rotate to cut into

2160-560: The Cairo Citadel at 280 feet (85 m) deep and the Pozzo di San Patrizio (St. Patrick's Well) built in 1527 in Orvieto, Italy , at 61 metres (200 ft) deep by 13 metres (43 ft) wide are both larger by volume. Driven wells may be very simply created in unconsolidated material with a well hole structure , which consists of a hardened drive point and a screen (perforated pipe). The point

2232-578: The Great Dividing Range where only cattle raising was possible because of dingo attacks on sheep. The original Kunderang Station, on the eastern fall of the Great Dividing Range was taken up by Captain George Jobling as an outstation, and later sold under the Subdivision of Runs Act 1884. Kunderang was one of the few Great Dividing Range stations which was inhabited. The isolated homestead here,

2304-561: The Top End heat and cattle ticks . The Brucellosis and Tuberculosis Eradication Campaign (BTEC) was a national program to eradicate bovine brucellosis and bovine tuberculosis that commenced in 1970 after years of local jurisdictional activities. In the 1970s, interest rates soared and the American beef market collapsed causing the beef depression. A fat bullock was then worth less than a pair of locally made elastic side riding boots. The cattle herd

2376-508: The bacteria , viruses , parasites , and fungi that contaminate well water comes from fecal material from humans and other animals. Common bacterial contaminants include E. coli , Salmonella , Shigella , and Campylobacter jejuni . Common viral contaminants include norovirus , sapovirus , rotavirus , enteroviruses , and hepatitis A and E . Parasites include Giardia lamblia , Cryptosporidium , Cyclospora cayetanensis , and microsporidia . Chemical contamination

2448-710: The filtration of the contaminants of concern, and additional protection may be garnered by installing well-casing screens only at depths where contamination is not present. Wellwater for personal use is often filtered with reverse osmosis water processors; this process can remove very small particles. A simple, effective way of killing microorganisms is to bring the water to a full boil for one to three minutes, depending on location. A household well contaminated by microorganisms can initially be treated by shock chlorination using bleach, generating concentrations hundreds of times greater than found in community water systems; however, this will not fix any structural problems that led to

2520-444: The water table . The excavation is braced horizontally to avoid landslide or erosion endangering the people digging. They can be lined with stone or brick; extending this lining upwards above the ground surface to form a wall around the well serves to reduce both contamination and accidental falls into the well. A more modern method called caissoning uses reinforced concrete or plain concrete pre-cast well rings that are lowered into

2592-547: The East Kimberley, Victoria River and Barkly Tablelands regions in Northern Australia. Cattle station has a parallel term, sheep station , for those stations carrying sheep rather than cattle. In most cases the stations are in a rangeland context on pastoral leases . Many are larger than small countries. Some stations are not exclusively sheep or cattle stations but have a mix of cattle, sheep and even goats to make

2664-712: The Jezreel Valley. Wells for other purposes came along much later, historically. The first recorded salt well was dug in the Sichuan province of China around 2,250 years ago. This was the first time that ancient water well technology was applied successfully for the exploitation of salt, and marked the beginning of Sichuan's salt drilling industry. The earliest known oil wells were also drilled in China, in 347 CE. These wells had depths of up to about 240 metres (790 ft) and were drilled using bits attached to bamboo poles. The oil

2736-461: The casing during construction and filling the casing annulus with an appropriate sealing material. The sealing material (grout) should be placed from immediately above the production zone back to surface, because, in the absence of a correctly constructed casing seal, contaminated fluid can travel into the well through the casing annulus. Centering devices are important (usually one per length of casing or at maximum intervals of 9 m) to ensure that

2808-699: The coast near modern Haifa in Israel . Wood-lined wells are known from the early Neolithic Linear Pottery culture , for example in Ostrov, Czech Republic, dated 5265 BC, Kückhoven (an outlying centre of Erkelenz ), dated 5300 BC, and Eythra in Schletz (an outlying centre of Asparn an der Zaya ) in Austria , dated 5200 BC. The neolithic Chinese discovered and made extensive use of deep drilled groundwater for drinking. The Chinese text The Book of Changes , originally

2880-480: The contamination and generally requires some expertise and testing for effective application. After the filtration process, it is common to implement an ultraviolet (UV) system to kill pathogens in the water. UV light affects the DNA of the pathogen by UV-C photons breaking through the cell wall. UV disinfection has been gaining popularity in the past decades as it is a chemical-free method of water treatment. A risk with

2952-522: The design and installation of private and municipal septic systems take all these factors into account so that nearby drinking water sources are protected. Education of the general population in society also plays an important role in protecting drinking water. Cleanup of contaminated groundwater tends to be very costly. Effective remediation of groundwater is generally very difficult. Contamination of groundwater from surface and subsurface sources can usually be dramatically reduced by correctly centering

3024-424: The drilled well, vertically stacked with their ends nested and either glued or splined together. The sections of casing are usually 6 metres (20 ft) or more in length, and 4 to 12 in (10 to 30 cm) in diameter, depending on the intended use of the well and local groundwater conditions. Surface contamination of wells in the United States is typically controlled by the use of a surface seal . A large hole

3096-434: The drilling process is completed, regardless of the machinery used. The oldest form of drilling machinery is the cable tool , still used today. Specifically designed to raise and lower a bit into the bore hole, the spudding of the drill causes the bit to be raised and dropped onto the bottom of the hole, and the design of the cable causes the bit to twist at approximately 1 ⁄ 4 revolution per drop, thereby creating

3168-443: The employees. Storage sheds and cattle yards are also sited near the homestead. Other structures depend on the size and location of the station. Isolated stations will have a mechanic's workshop, schoolroom, a small general store to supply essentials, and possibly an entertainment or bar area for the owners and staff. Water may be supplied from a river, bores or dams , in conjunction with rainwater tanks. Nowadays, if rural mains power

3240-435: The excavation proceeds. A more modern method called caissoning uses pre-cast reinforced concrete well rings that are lowered into the hole. Driven wells can be created in unconsolidated material with a well hole structure, which consists of a hardened drive point and a screen of perforated pipe, after which a pump is installed to collect the water. Deeper wells can be excavated by hand drilling methods or machine drilling, using

3312-513: The formation, thus the term "drilling." Drilled wells can be excavated by simple hand drilling methods (augering, sludging, jetting, driving, hand percussion) or machine drilling (auger, rotary, percussion, down the hole hammer). Deep rock rotary drilling method is most common. Rotary can be used in 90% of formation types (consolidated). Drilled wells can get water from a much deeper level than dug wells can − often down to several hundred metres. Drilled wells with electric pumps are used throughout

3384-427: The grouted annular space is of even thickness. Upon the construction of a new test well, it is considered best practice to invest in a complete battery of chemical and biological tests on the well water in question. Point-of-use treatment is available for individual properties and treatment plants are often constructed for municipal water supplies that suffer from contamination. Most of these treatment methods involve

3456-694: The growth of iron and manganese bacteria that can form slimy black colonies that clog pipes. The quality of the well water can be significantly increased by lining the well, sealing the well head, fitting a self-priming hand pump, constructing an apron, ensuring the area is kept clean and free from stagnant water and animals, moving sources of contamination ( pit latrines , garbage pits, on-site sewer systems ) and carrying out hygiene education. The well should be cleaned with 1% chlorine solution after construction and periodically every 6 months. Well holes should be covered to prevent loose debris, animals, animal excrement, and wind-blown foreign matter from falling into

3528-416: The hole and decomposing. The cover should be able to be in place at all times, including when drawing water from the well. A suspended roof over an open hole helps to some degree, but ideally the cover should be tight fitting and fully enclosing, with only a screened air vent. Minimum distances and soil percolation requirements between sewage disposal sites and water wells need to be observed. Rules regarding

3600-635: The hole. A well-digging team digs under a cutting ring and the well column slowly sinks into the aquifer , whilst protecting the team from collapse of the well bore . Hand-dug wells are inexpensive and low tech (compared to drilling) and they use mostly manual labour to access groundwater in rural locations of developing countries. They may be built with a high degree of community participation, or by local entrepreneurs who specialize in hand-dug wells. They have been successfully excavated to 60 metres (200 ft). They have low operational and maintenance costs, in part because water can be extracted by hand, without

3672-403: The homestead looted of all firearms and ammunition. A young boy was sent with a threatening message for any white men who attempted to follow the perpetrators. A few months later a policeman, Constable Flinders, attempted to apprehend the suspect at his camp on Boolka Creek on Bohemia Downs Station . The suspect, named Banjo, was shot and killed during the arrest. In October of that year, more than

3744-476: The main activity of which is the rearing of cattle. The owner of a cattle station is called a grazier . The largest cattle station in the world is Anna Creek Station in South Australia , which covers an area of 23,677 square kilometres (9,142 sq mi; 5,851,000 acres). Each station has a homestead where the property owner or the manager lives. Nearby cottages or staff quarters provide housing for

3816-425: The owner less vulnerable to changes in the wool or beef prices. The phrase is also in traditional Australian English to denote something large and/or important. Well Wells have traditionally been sunk by hand digging, as is still the case in rural areas of the developing world. These wells are inexpensive and low-tech as they use mostly manual labour, and the structure can be lined with brick or stone as

3888-406: The placement of water wells is soil salination which occurs when the water table of the soil begins to drop and salt begins to accumulate as the soil begins to dry out. Another environmental problem that is very prevalent in water well drilling is the potential for methane to seep through. The potential for soil salination is a large risk when choosing the placement of water wells. Soil salination

3960-478: The screen and the borehole or casing. This allows the water to be filtered of unwanted materials before entering the well and pumping zone. There are two broad classes of drilled-well types, based on the type of aquifer the well is in: A special type of water well may be constructed adjacent to freshwater lakes or streams. Commonly called a collector well but sometimes referred to by the trade name Ranney well or Ranney collector , this type of well involves sinking

4032-413: The surface to the next confining layer that keeps contaminants from traveling down the outer sidewalls of the casing or borehole and into the aquifer . In addition, wells are typically capped with either an engineered well cap or seal that vents air through a screen into the well, but keeps insects, small animals, and unauthorized persons from accessing the well. At the bottom of wells, based on formation,

4104-418: The use of the well: A water well constructed for pumping groundwater can be used passively as a monitoring well and a small diameter well can be pumped, but this distinction by use is common. Before excavation, information about the geology, water table depth, seasonal fluctuations, recharge area and rate should be found if possible. This work can be done by a hydrogeologist , or a groundwater surveyor using

4176-463: The water table falls and the surrounding soil begins to dry out. Another environmental problem is the potential for methane to seep into the water. Very early Neolithic wells are known from the Eastern Mediterranean . The oldest reliably dated well is from the pre-pottery neolithic (PPN) site of Kissonerga-Mylouthkia on Cyprus . At around 8400 BC a shaft (well 116) of circular diameter

4248-505: The well bore, falling objects and asphyxiation, including from dewatering pump exhaust fumes. The Woodingdean Water Well , hand-dug between 1858 and 1862, is the deepest hand-dug well at 392 metres (1,285 ft). The Big Well in Greensburg, Kansas , is billed as the world's largest hand-dug well, at 109 feet (33 m) deep and 32 feet (9.8 m) in diameter. However, the Well of Joseph in

4320-400: The well slowly decreases and is removed from the well. Rock wells are typically cased with a PVC liner/casing and screen or slotted casing at the bottom, this is mostly present just to keep rocks from entering the pump assembly. Some wells utilize a filter pack method, where an undersized screen or slotted casing is placed inside the well and a filter medium is packed around the screen, between

4392-402: The world, typically in rural or sparsely populated areas, though many urban areas are supplied partly by municipal wells. Most shallow well drilling machines are mounted on large trucks, trailers, or tracked vehicle carriages. Water wells typically range from 3 to 18 metres (10–60 ft) deep, but in some areas it can go deeper than 900 metres (3,000 ft). Rotary drilling machines use

4464-672: Was a subsidiary homestead or other dwelling on Australian sheep or cattle stations that was more than a day's return travel from the main homestead. Although the term later came to be more commonly used to describe a specific type of Aboriginal settlement, also known as a homeland community , it is still used on cattle stations today, for example the Sturt Creek Outstation of the Ruby Plains Station in The Kimberley , among others. The cattle station now known as Pigeon Hole

4536-1138: Was associated with the opening up and stocking of several cattle stations in the Victoria River district and the Ord River region. The Gordon brothers and Nathaniel Buchanan took up Wave Hill on the Victoria River in 1883, one of the first cattle stations established west of the Telegraph Line. Their nearest neighbour was 200 miles (322 km) away. By 1898 James Tyson (8 April 1819 – 4 December 1898), held 5,329,214 acres (2,156,680 ha) including 352,332 acres (142,585 ha) freehold. His stations included Bangate, Goondublui, Juanbung, Tupra and Mooroonowa in New South Wales; Heyfield in Victoria; and Glenormiston , Swanvale, Meteor Downs and Albinia Downs, Babbiloora, Carnarvon, Tully, Wyobie, Felton, Mount Russell and Tinnenburra in Queensland. Sidney Kidman (1857–1935) set up

4608-787: Was built of solid Australian red cedar ( Toona ciliata ). Several major events have affected cattle stations starting with the Second World War and including the beef depression of the early 1970s, the technological achievements of the 1980s and the advent of live export markets in the more recent years. Roads and communications were greatly improved as a result of the War. Many of the Northern Territory cattle stations had been previously owned by English companies who also did not pay tax in Australia. The 33,280 square kilometres Victoria River Downs

4680-517: Was burned to evaporate brine and produce salt . By the 10th century, extensive bamboo pipelines connected oil wells with salt springs. The ancient records of China and Japan are said to contain many allusions to the use of natural gas for lighting and heating. Petroleum was known as Burning water in Japan in the 7th century. Until recent centuries, all artificial wells were pumpless hand-dug wells of varying degrees of sophistication, and they remain

4752-407: Was closed early in 1925 after falling into disuse as a result of stockmen being attacked by Aborigines. Stock from Billiluna had to be transported via Wyndham instead of overlanding using the track. The Billiluna Pastoral Company requested the track be reopened but the government claimed it would cost £5,625 and take six months to repair and refused. In the early twentieth century, Billiluna stock
