History Of Anthracite Coal Mining In Pennsylvania
There are two types of coal found in Pennsylvania: anthracite (the “hard coal” found in Northeastern Pennsylvania below the Allegheny Ridge southwest to Harrisburg; also called “stone coal”, “rock coal” in the 1800s) and bituminous (“soft coal”, found west of the Allegheny Front escarpment). Anthracite coal is a natural mineral with a high carbon and energy content that gives off light and heat ( produced energy) when burned, making it useful as a fuel. It was possibly first used in Pennsylvania as a fuel in 1769, but its real history begins with a documented discovery near Summit Hill and the founding of the Lehigh Coal Mine Company in 1792 to sporadically send expeditions to the wilderness atop Pisgah Ridge to mine the deposits, mostly with notable lack of great success, over the next 22 years. The owners of this company were absentee management—reliant on teams of workers sent under a foreman to fell timber to build so called 'Arks' ( high-sided punts), then ...

Josiah White (1780-1850) Erskine Hazard (1790-1865)
Josiah White (1781–1850) was a Pennsylvania industrialist and key figure in the Industrial Revolution in the United States, American Industrial Revolution. Career White began early factory-centered mill production in 1808 in Hydropower, water powered ironworks near Philadelphia, along with his partner, Erskine Hazard, when they quickly found that their first mill at the East Falls, Philadelphia, East Falls, Pennsylvanial to be much too small. Subsequently, they built a more elaborate and larger mill nearby to refine pig iron and produce cast iron artifacts and roll wrought bar iron goods, including nails and wire. The pair were especially influential after 1814 in helping make the American Industrial Revolution accelerate its building momentum by agitating for infrastructure investment, sponsoring two key river navigations and the nation's first long railway, and then after initial success, increasingly supplying an expanding part of the country's overall energy needs including t ...

Mule
The mule is a domestic equine hybrid between a donkey and a horse. It is the offspring of a male donkey (a jack) and a female horse (a mare). The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a female donkey (a jenny) and a male horse (a stallion). Mules vary widely in size, and may be of any color. They are more patient, hardier and longer-lived than horses, and are perceived as less obstinate and more intelligent than donkeys. Terminology A female mule that has oestrus cycles, and which could thus in theory carry a foetus, is called a "molly" or "Molly mule", though the term is sometimes used to refer to female mules in general. A male mule is properly called a "horse mule", though often called a "john mule", which is the correct term for a gelded mule. A young male mule is called a "mule co ...

Erie Canal
The Erie Canal is a historic canal in upstate New York that runs east-west between the Hudson River and Lake Erie. Completed in 1825, the canal was the first navigable waterway connecting the Atlantic Ocean to the Great Lakes, vastly reducing the costs of transporting people and goods across the Appalachians. In effect, the canal accelerated the settlement of the Great Lakes region, the westward expansion of the United States, and the economic ascendancy of New York State. It has been called "The Nation's First Superhighway." A canal from the Hudson to the Great Lakes was first proposed in the 1780s, but a formal survey was not conducted until 1808. The New York State Legislature authorized construction in 1817. Political opponents of the canal, and of its lead supporter New York Governor DeWitt Clinton, denigrated the project as "Clinton's Folly" and "Clinton's Big Ditch". Nonetheless, the canal saw quick success upon opening on October 26, 1825, with toll revenue covering the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Line Of Public Works
The Main Line of Public Works was a package of legislation passed by the Commonwealth of Pennsylvania in 1826 to establish a means of transporting freight between Philadelphia and Pittsburgh. It funded the construction of various long-proposed canal and road projects, mostly in southern Pennsylvania, that became a canal system and later added railroads. Built between 1826 and 1834, it established the Pennsylvania Canal System and the Allegheny Portage Railroad. Later amendments substituted a new technology, railroads, in place of the planned but costly canal connecting the Delaware River (Philadelphia) to the Susquehanna River. Historic background Trans-Appalachian settlement had begun in earnest during the latter years of the French and Indian War (1754-1763). Following the war, the British government made several agreements, primarily with the Iroquois Confederacy, which resulted in official policies to curb the expansion of settlement in the colonial Mid-West. This was one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enabling Legislation
An enabling act is a piece of legislation by which a legislative body grants an entity which depends on it (for authorization or legitimacy) the power to take certain actions. For example, enabling acts often establish government agencies to carry out specific government policies in a modern nation. The effects of enabling acts from different times and places vary widely. Germany The German word for an enabling act is ''Ermächtigungsgesetz''. It usually refers to the enabling act of 23 March 1933 which became a cornerstone of Adolf Hitler's seizure of power. Acts of 1914–1927 The first enabling act is dated from 4 August 1914 just after the German entry into World War I. With the vote of the Social Democratic Party, the Reichstag (the German Empire's parliament) agreed to give the government certain powers to take the necessary economic measures during the war. Such enabling acts were also common in other countries. The Reichstag had to be informed, and had the right to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Transport
Maritime transport (or ocean transport) and hydraulic effluvial transport, or more generally waterborne transport, is the transport of people (passengers) or goods (cargo) via waterways. Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air, despite fluctuating exchange rates and a fee placed on top of freighting charges for carrier companies known as the currency adjustment factor. Maritime transport accounts for roughly 80% of international trade, according to UNCTAD in 2020. Maritime transport can be realized over any distance by boat, ship, sailboat or barge, over oceans and lakes, through canals or along rivers. Shipping may be for commerce, recreation, or military purposes. While extensive inland shipping is less critical today, the major waterwa ...

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Delaware Canal
The Delaware Division of the Pennsylvania Canal, more commonly called the Delaware Canal, runs for parallel to the right bank of the Delaware River from the entry locks near the mouth of the Lehigh River and terminal end of the Lehigh Canal at Easton south to Bristol. At Easton, which today is the home of The National Canal Museum, the Delaware Canal also connected with the Morris Canal built to carry anthracite coal to energy-starved New Jersey industries. Later, with a crossing-lock constructed at New Hope, the New Hope 'outlet lock' (1847) connected by Cable Ferry to enter at Lambertville, NJ; where it connected to a feeder navigation/canal that began at Bull's Island opposite Lumberville; which then ran over south along the New Jersey bank of the Delaware River through Trenton to Bordentown, the west end of the Delaware and Raritan Canal (1834) to New York City via New Brunswick. The Commonwealth of Pennsylvania built the Delaware canal to feed anthracite stone coal to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schooner
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for priv ...

Steam Tug
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness comp ...

Lock (water Transport)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval en ...
