Roubaix, South Dakota
Roubaix (), formerly known as Perry or Lewisville, is an unincorporated community in Lawrence County, South Dakota, United States. It is not monitored by the U.S. Census Bureau. Naming Roubaix was originally called ''Lewisville'', but it was changed to ''Perry'' when the town gained a post office. When the Chicago, Burlington and Quincy Railroad began building into the Black Hills, the town again changed its name to avoid confusion with Terry, which was nearby. ''Roubaix'' was chosen in honor of the hometown of local Frenchman Pierre Wibaux, who was one of the Uncle Sam Mine's main investors. History Founding and growth The mining camp was first settled in 1876. It was first a placer mining camp, with the primary source of gold being nearby Elk Creek. The town nearly disappeared after the Uncle Sam Mine was shut down in 1880, and a forest fire destroyed a large portion of the town. The grand reopening of Roubaix and its official recognition as a town was marked by a celebrati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unincorporated Area
An unincorporated area is a region that is not governed by a local municipal corporation. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world either have no unincorporated areas at all or these are very rare: typically remote, outlying, sparsely populated or List of uninhabited regions, uninhabited areas.

Church (building)
A church, church building or church house is a building used for Christian worship services and other Christian religious activities. The earliest identified Christian church is a house church founded between 233 and 256. From the 11th through the 14th centuries, there was a wave of church construction in Western Europe. Sometimes, the word ''church'' is used by analogy for the buildings of other religions. ''Church'' is also used to describe the Christian religious community as a whole, or a body or an assembly of Christian believers around the world. In traditional Christian architecture, the plan view of a church often forms a Christian cross; the center aisle and seating representing the vertical beam with the Church architecture#Characteristics of the early Christian church building, bema and altar forming the horizontal. Towers or domes may inspire contemplation of the heavens. Modern churches have a variety of architectural styles and layouts. Some buildings designe ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Sawmill
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is of simple operation. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig ("Alaskan sawmill"), with similar horizontal operation. Before the invention of the sawmill, boards were made in various manual ways, either rived (split) and planed, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia Minor dating back to the 3rd century AD. Other water-powered mills followe ...

Water Pump
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: ''direct lift'', ''displacement'', and ''gravity'' pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a casing contains only one revolving impeller, it is called a single-stage pump. Whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tigerville, South Dakota
Tigerville or Tiger City (1878–1885) is a ghost town in the Black Hills of Pennington County, South Dakota, United States. The old mining town exemplifies the boom-and-bust fate of many Western towns.Parker, Watson, and Hugh K. Lambert. ''Black Hills Ghost Towns.'' First ed. Vol. 1. Chicago, IL: The Swallow Press Incorporated, 1974. 188. 1 vols. Print. Naming The town's name might have come from the Bengal Tiger Mine, located 2–3 miles away. Others say that the name came from the unpatented Lucky Tiger claims Numbers 1, 2, and 3; though these do not show up on maps, locals say that the claims were nearby the town. History Tigerville was founded in 1878 in the King Solomon Mine area, which was known for its gold and quartz placer deposits. It had a post office, two stores, three saloons, blacksmith, school, and a stage barn, which was a stop on the Cheyenne-Custer-Deadwood line. The nearby Bengal Tiger Mine, despite reportedly having promising mineral deposits, was never succ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (as ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

School
A school is an educational institution designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the '' Regional terms'' section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university. In addition to these core schools, students in a given country may also attend schools before and after primary (elementary in the U.S.) and secondary (middle school in the U.S.) education. Kindergarten or preschool provide some schooling to very young children (typically ages 3–5). University, vocational school, college or seminary may be avail ...

Trade Union
A trade union (labor union in American English), often simply referred to as a union, is an organization of workers intent on "maintaining or improving the conditions of their employment", ch. I such as attaining better wages and benefits (such as holiday, health care, and retirement), improving working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting the integrity of their trade through the increased bargaining power wielded by solidarity among workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The delegate staff of the trade union representation in the workforce are usually made up of workplace volunteers who are often appointed by members in democratic elections. The trade union, through an elected leadership and bargaining committee, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whist
Whist is a classic English trick-taking card game which was widely played in the 18th and 19th centuries. Although the rules are simple, there is scope for strategic play. History Whist is a descendant of the 16th-century game of ''trump'' or ''ruff''. Whist replaced the popular variant of ''trump'' known as ruff and honours. The game takes its name from the 17th-century ''whist'' (or ''wist'') meaning ''quiet'', ''silent'', ''attentive'', which is the root of the modern ''wistful''. According to Daines Barrington, whist was first played on scientific principles by a party of gentlemen who frequented the Crown Coffee House in Bedford Row, London, around 1728. Edmond Hoyle, suspected to be a member of this group, began to tutor wealthy young gentlemen in the game and published ''A Short Treatise on the Game of Whist'' in 1742. It became the standard text and rules for the game for the next hundred years. In 1862, Henry Jones, writing under the pseudonym "Cavendish", publis ...
