Corduroy Road
A corduroy road or log road is a type of road or timber trackway made by placing logs, perpendicular to the direction of the road over a low or swampy area. The result is an improvement over impassable mud or dirt roads, yet rough in the best of conditions and a hazard to horses due to shifting loose logs. Corduroy roads can also be built as a foundation for other surfacing. If the logs are buried in wet, acidic, anaerobic soils such as peat or muskeg, they decay very slowly. A few corduroy road foundations that date back to the early 20th century still exist in North America. One example is the Alaska Highway between Burwash Landing and Koidern, Yukon, Canada, which was rebuilt in 1943, less than a year after the original route was graded on thin soil and vegetation over permafrost, by using corduroy, then building a gravel road on top. During the 1980s, the gravel was covered with a chip-seal. The late 1990s saw replacement of this road with modern road construction, ...

Chipseal
Chipseal (also chip seal or chip and seal) is a pavement surface treatment that combines one or more layer(s) of asphalt with one or more layer(s) of fine aggregate. In the United States, chipseals are typically used on rural roads carrying lower traffic volumes, and the process is often referred to as asphaltic surface treatment. This type of surface has a variety of other names including tar-seal or tarseal, tar and chip, sprayed seal or surface dressing. In Australia as well as New Zealand, chipseal roads are common, including usage on major highways Uses Chipsealing is cheaper than resurfacing an asphalt concrete or a Portland cement concrete pavement, but not as long-lasting. Installation Chipseals are constructed by evenly distributing a thin base of hot tar, bitumen or asphalt onto an existing pavement and then embedding finely graded aggregate into it. The aggregate is evenly distributed over the hot seal spray, then rolled into the bitumen using heavy rubber tired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skidder
A skidder is any type of heavy vehicle used in a logging operation for pulling cut trees out of a forest in a process called "skidding", in which the logs are transported from the cutting site to a landing. There they are loaded onto trucks (or in times past, railroad cars or flumes), and sent to the mill. One exception is that in the early days of logging, when distances from the timberline to the mill were shorter, the landing stage was omitted altogether, and the "skidder" would have been used as the main road vehicle, in place of the trucks, railroad, or flume. Modern forms of skidders can pull trees with a cable/winch (''cable skidder''), just like the old steam donkeys, or with a hydraulic grapple either on boom (''grapple skidder'') or on the back of the frame ''(clambunk skidder)''. History Early skidders were pulled by a team of oxen, horses or mules. The driver would straddle the cart over felled logs, where dangling tongs would be positioned to raise the end of th ...

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions, though their efficiency for these purposes has been challenged. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Illegal logging refers to the harvesting, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, i ...

William Tecumseh Sherman
William Tecumseh Sherman ( ; February 8, 1820February 14, 1891) was an American soldier, businessman, educator, and author. He served as a general in the Union Army during the American Civil War (1861–1865), achieving recognition for his command of military strategy as well as criticism for the harshness of the scorched-earth policies that he implemented against the Confederate States. British military theorist and historian B. H. Liddell Hart declared that Sherman was "the first modern general". Born in Ohio into a politically prominent family, Sherman graduated in 1840 from the United States Military Academy at West Point. He interrupted his military career in 1853 to pursue private business ventures, without much success. In 1859, he became superintendent of the Louisiana State Seminary of Learning & Military Academy (now Louisiana State University), a position from which he resigned when Louisiana seceded from the Union. Sherman commanded a brigade of volunteers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Shiloh
The Battle of Shiloh (also known as the Battle of Pittsburg Landing) was fought on April 6–7, 1862, in the American Civil War. The fighting took place in southwestern Tennessee, which was part of the war's Western Theater. The battlefield is located between a church named Shiloh and Pittsburg Landing, which is on the Tennessee River. Two Union armies combined to defeat the Confederate Army of Mississippi. Major General Ulysses S. Grant was the Union commander, while General Albert Sidney Johnston was the Confederate commander. The Confederate army hoped to defeat Grant's Army of the Tennessee before it could be reinforced and resupplied. Although it made considerable gains with a surprise attack during the first day of the battle, Johnston was mortally wounded and Grant's army was not eliminated. Overnight, Grant's Army of the Tennessee was reinforced by one of its divisions stationed farther north, and it was also joined by portions of the Army of the Ohio. This sec ...

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 Da ...

Hereward The Wake
Hereward the Wake (Traditional pronunciation /ˈhɛ.rɛ.ward/, modern pronunciation /ˈhɛ.rɪ.wəd/) (1035 – 1072) (also known as Hereward the Outlaw or Hereward the Exile) was an Anglo-Saxon nobleman and a leader of local resistance to the Norman Conquest of England. His base, when leading the rebellion against the Norman rulers, was the Isle of Ely in eastern England. According to legend he roamed the Fens, which nowadays covers parts of the modern counties of Cambridgeshire, Lincolnshire and Norfolk, leading popular opposition to William the Conqueror. ''Hereward'' is an Old English name, composed of the elements ''here'', "army", and ''ward'' "guard" (cognate with the Old High German name ''Heriwart''). The epithet "the Wake", first recorded in the 14th century, may mean "the watchful", or derive from the Anglo-Norman Wake family who later claimed descent from him. Primary sources Several primary sources exist for Hereward's life, though the accuracy of thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
