American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Dalecarlia Reservoir
Dalecarlia Reservoir is the primary storage basin for drinking water in Washington, D.C., fed by an underground aqueduct in turn fed by low dams which divert portions of the Potomac River near Great Falls and Little Falls. The reservoir is located between Spring Valley and the Palisades, two neighborhoods in Northwest Washington, and Brookmont, a neighborhood in Montgomery County, Maryland. The reservoir was completed in 1858 by the United States Army Corps of Engineers as part of the Washington Aqueduct project. It began providing water on January 3, 1859. Initially the reservoir provided water to the city from the adjacent Little Falls Branch until the aqueduct construction was completed. Regular water service from the Potomac River source through the aqueduct commenced in 1864. The reservoir was modified in 1895 and 1935 to improve water quality and increase water supply. In 1942, the headquarters of the Army Map Service was established on the grounds adjacent to the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macadam
Macadam is a type of road construction, pioneered by Scottish engineer John Loudon McAdam around 1820, in which crushed stone is placed in shallow, convex layers and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a cement or bituminous binder to keep dust and stones together. The method simplified what had been considered state-of-the-art at that point. Predecessors Pierre-Marie-Jérôme Trésaguet Pierre-Marie-Jérôme Trésaguet is sometimes considered the first person to bring post-Roman science to road building. A Frenchman from an engineering family, he worked paving roads in Paris from 1757 to 1764. As chief engineer of road construction of Limoges, he had opportunity to develop a better and cheaper method of road construction. In 1775, Tresaguet became engineer-general and presented his answer for road improvement in France, which soon became standard practice there. ...

Florida Avenue
Florida Avenue is a major street in Washington, D.C. It was originally named Boundary Street, because it formed the northern boundary of the Federal City under the 1791 L'Enfant Plan. With the growth of the city beyond its original borders, Boundary Street was renamed Florida Avenue in 1890. History On July 9, 1790, Congress passed the Residence Act, which approved the creation of a national capital on the Potomac River. The exact location was to be selected by President George Washington, who chose a portion of the states of Maryland and Virginia on January 24, 1791. Originally, government officials did not foresee that the city of Washington would expand to fill the boundaries of the entire District of Columbia. The "Federal City", or City of Washington, originally lay within an area bounded by Boundary Street (northwest and northeast), 15th Street Northeast, East Capitol Street, the Anacostia River, the Potomac River, and Rock Creek. The first section of Boundary Street to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
