Ijamsville, Maryland
Ijamsville ( ) is an unincorporated community located southeast of Frederick, in Frederick County, Maryland, United States. The town was founded by Plummer Ijams, a descendant of Welsh immigrants, from whom the town took its name. The discovery of high-quality slate in the area led to Ijamsville's brief era as a mining town, which lasted until it transitioned to agriculture in the mid-1800s. In the mid-to-late 20th century, large quantities of land in Ijamsville were purchased by developers, and the town became primarily residential as a suburb of Frederick, Baltimore, and D.C. History Founding and name In 1785, a Maryland native named Plummer Ijams moved to Frederick County, having purchased a tract of land called the "Paradise Grant" from the government. His family was originally from Wales and emigrated to the Anne Arundel region sometime during the 17th century. The land was approximately southeast of the city of Frederick and cost Plummer one pound, fifteen shillings, ... [...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.

Penny (British Pre-decimal Coin)
The British pre-decimal penny was a denomination of sterling coinage worth of one pound or of one shilling. Its symbol was ''d'', from the Roman denarius. It was a continuation of the earlier English penny, and in Scotland it had the same monetary value as one pre-1707 Scottish shilling. The penny was originally minted in silver, but from the late 18th century it was minted in copper, and then after 1860 in bronze. The plural of "penny" is "pence" when referring to an amount of money, and "pennies" when referring to a number of coins. Thus 8''d'' is eight pence, but "eight pennies" means specifically eight individual penny coins. Before Decimal Day in 1971, sterling used the Carolingian monetary system (£sd), under which the largest unit was a pound (£) divisible into 20 shillings (s), each of 12 pence (d). The penny was withdrawn in 1971 due to decimalisation, and replaced (in effect) by the decimal half new penny, with p being worth 1.2''d''. History The kingdoms o ...

Westminster, Maryland
Westminster is a city in northern Maryland, United States. It is the seat of Carroll County. The city's population was 18,590 at the 2010 census. Westminster is an outlying community within the Baltimore-Towson, MD MSA, which is part of a greater Washington-Baltimore-Northern Virginia, DC-MD-VA-WV CSA. History William Winchester (1706-1790) purchased approximately 167 acres of land called White's Level in 1754 which became known as the city of Winchester. The Maryland General Assembly later changed the name of the town to Westminster to avoid confusion with Winchester, the seat of nearby Frederick County, Virginia. On June 28, 1863, the cavalry skirmish known as Corbit's Charge was fought in the streets of Westminster, when two companies of Delaware cavalry attacked a much larger Confederate force under General J. E. B. Stuart, during the Gettysburg Campaign. In April 1865, Joseph Shaw, newspaper editor, had his presses wrecked and his business destroyed, and was subsequent ...

Phyllite
Phyllite ( ) is a type of foliated metamorphic rock created from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation.Stephen Marshak ''Essentials of Geology'', 3rd ed. It is primarily composed of quartz, sericite mica, and chlorite. Phyllite has fine-grained mica flakes, whereas slate has extremely fine mica flakes, and schist has large mica flakes, all mica flakes of which have achieved a preferred orientation. Among foliated metamorphic rocks, it represents a gradation in the degree of metamorphism between slate and schist. The minute crystals of graphite, sericite, or chlorite, or the translucent fine-grained white mica, impart a silky, sometimes golden sheen to the surfaces of cleavage, called "phyllitic luster". The word comes from the Greek ''phyllon'', meaning "leaf". The protolith (or parent rock) for phyllite is shale or pelite, or slate, which in turn came from a shale protolith. Its constituent platy minerals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Airy, MD
Mount Airy is a town in Carroll and Frederick counties in the U.S. state of Maryland. It is part of both the Washington Metropolitan Area and Baltimore Metropolitan Area.

Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Tracks In Ijamsville, MD
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Captain (armed Forces)
The army rank of captain (from the French ) is a commissioned officer rank historically corresponding to the command of a company of soldiers. The rank is also used by some air forces and marine forces. Today, a captain is typically either the commander or second-in-command of a company or artillery battery (or United States Army cavalry troop or Commonwealth squadron). In the Chinese People's Liberation Army, a captain may also command a company, or be the second-in-command of a battalion. In some militaries, such as United States Army and Air Force and the British Army, captain is the entry-level rank for officer candidates possessing a professional degree, namely, most medical professionals (doctors, pharmacists, dentists) and lawyers. In the U.S. Army, lawyers who are not already officers at captain rank or above enter as lieutenants during training, and are promoted to the rank of captain after completion of their training if they are in the active component, or after a ...

War Of 1812
The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812 and, although peace terms were agreed upon in the December 1814 Treaty of Ghent, did not officially end until the peace treaty was ratified by Congress on 17 February 1815. Tensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed US colonial settlement in the Northwest Territory. These escalated in 1807 after the Royal Navy began enforcing tighter restrictions on American trade with France and press-ganged men they claimed as British subjects, even those with American citizenship certificates. Opinion in the US was split on how to respond, and although majorities in both the House and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gristmill
A gristmill (also: grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and Wheat middlings, middlings. The term can refer to either the Mill (grinding), grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding. History Early history The Greek geographer Strabo reports in his ''Geography'' a water-powered grain-mill to have existed near the palace of king Mithradates VI Eupator at Cabira, Asia Minor, before 71 BC. The early mills had horizontal paddle wheels, an arrangement which later became known as the "Water wheel#Vertical axis, Norse wheel", as many were found in Scandinavia. The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary "Mill machinery#Wat ...
