St. Julien Ravenel
St. Julien Ravenel (December 15, 1819 – March 16, 1882) was an American physician and agricultural chemist. During the American Civil War, he designed the torpedo boat CSS ''David'' that was used to attack the Union ironclad USS ''New Ironsides''. Following the war, he helped pioneer the use of fertilizers in agriculture and led the growth of phosphate fertilizer manufacturing in Charleston, South Carolina. Early career and family Born in Charleston, South Carolina, St. Julien was the oldest child of merchant and ship owner John Ravenel and his wife Anna Eliza Ford. After attending grammar schools in Charleston, he left for Morristown, New Jersey to continue his education. In 1840 he graduated from the Medical College in Charleston after studying medicine under J. E. Holbrook, then continued his studies for a summer in Philadelphia and a year at Paris, France. Returning to Charleston, he began to practice medicine and was named Demonstrator of Anatomy at the Medical College ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnolia Cemetery (Charleston, South Carolina)
Magnolia Cemetery is a historic rural cemetery in Charleston, South Carolina. The first board for the cemetery was assembled in 1849 with Edward C. Jones as the architect. It was dedicated in 1850; Charles Fraser delivered the dedication address. It was listed on the National Register of Historic Places as a Historic District in 1978. The location of the cemetery had previously been a plantation known as Magnolia Umbra, the house of which was described as a newly built house with five rooms in 1820. The cemetery was constructed during 1850, on plans laid out by Edward C. Jones, and included a Gothic chapel also designed by Jones which no longer exists. The chapel, which was located near the central lake, remained under construction until early 1851. Both the chapel and the porter's lodge sustained very heavy damage during the cemetery's occupation by federal forces during the Civil War. The porter's lodge at the entrance was demolished in 1868, but the chapel continued to be use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marl
Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae. Marl makes up the lower part of the cliffs of Dover, and the Channel Tunnel follows these marl layers between France and the United Kingdom. Marl is also a common sediment in post-glacial lakes, such as the marl ponds of the northeastern United States. Marl has been used as a soil conditioner and neutralizing agent for acid soil and in the manufacture of cement. Description Marl or marlstone is a carbonate-rich mud or mudstone which contains variable amounts of clays and silt. The term was originally loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions. These typically contain 35–65% clay and 65–35% carbonate. The te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirrhosis Of The Liver
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, and end-stage liver disease, is the impaired liver function caused by the formation of scar tissue known as fibrosis due to damage caused by liver disease. Damage causes tissue repair and subsequent formation of scar tissue, which over time can replace normal functioning tissue, leading to the impaired liver function of cirrhosis. The disease typically develops slowly over months or years. Early symptoms may include tiredness, weakness, loss of appetite, unexplained weight loss, nausea and vomiting, and discomfort in the right upper quadrant of the abdomen. As the disease worsens, symptoms may include itchiness, swelling in the lower legs, fluid build-up in the abdomen, jaundice, bruising easily, and the development of spider-like blood vessels in the skin. The fluid build-up in the abdomen may become spontaneously infected. More serious complications include hepatic encephalopathy, bleeding from dilated vei ...

Artesian Wells
An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay, which apply positive pressure to the water contained within the aquifer. If a well were to be sunk into an artesian aquifer, water in the well-pipe would rise to a height corresponding to the point where hydrostatic equilibrium is reached. A well drilled into such an aquifer is called an ''artesian well''. If water reaches the ground surface under the natural pressure of the aquifer, the well is termed a ''flowing artesian well''. Fossil water aquifers can also be artesian if they are under sufficient pressure from the surrounding rocks, similar to how many newly tapped oil wells are pressurized. From the previous statement, it can be inferred that not all aquifers are artesian (i.e., water table aquifers occur where the groundwater level at the top of the aquifer is at equilibrium with atmospher ...

Phosphate
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one or two protons gives the dihydrogen phosphate ion and the hydrogen phosphate ion ion, respectively. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charleston Harbor
The Charleston Harbor is an inlet (8 sq mi/20.7 km²) of the Atlantic Ocean at Charleston, South Carolina. The inlet is formed by the junction of Ashley and Cooper rivers at . Morris and Sullivan's Islands shelter the entrance. Charleston Harbor forms part of the Intracoastal Waterway. History The harbor contains Fort Sumter, the site of the first shots of the American Civil War. Charleston Harbor was also the site of the first successful submarine attack in history on February 17, 1864, when the ''H.L. Hunley'' made a daring night attack on the USS ''Housatonic'', during the American Civil War. The 12-foot natural depth of the harbor was a major reason for the establishment and growth of Charleston. The Rivers and Harbors Act of 1852 authorized the federal government to dredge the channels of the harbor to a depth of 17 feet. This deepening work was interrupted by the Civil War A civil war or intrastate war is a war between organized groups within the ...

Ross Winans
Ross Winans (1796–1877) was an American inventor, mechanic, and builder of locomotives and railroad machinery. He is also noted for design of pioneering cigar-hulled ships. Winans, one of the United States' first multi-millionaires, was involved in national and state politics, a southern-sympathizer and was a vehement "states' rights" advocate. Winans was briefly arrested after the Baltimore riot of 1861. His outspoken anti-federal stance as a member of the Maryland House of Delegates, the lower chamber of the General Assembly, (state legislature) led to his temporary arrest on May 14, 1861. At the time of his arrest, Winans was returning on a Baltimore and Ohio Railroad train from an early session of the legislature that was being held in the western Maryland town of Frederick to avoid the Union Army-occupied state capital of Annapolis in April–May 1861 to consider the possibilities of state secession during the early decisive period of the American Civil War. Winans was r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Blockade
The Union blockade in the American Civil War was a naval strategy by the United States to prevent the Confederacy from trading. The blockade was proclaimed by President Abraham Lincoln in April 1861, and required the monitoring of of Atlantic and Gulf coastline, including 12 major ports, notably New Orleans and Mobile. Those blockade runners fast enough to evade the Union Navy could carry only a small fraction of the supplies needed. They were operated largely by foreign citizens, making use of neutral ports such as Havana, Nassau and Bermuda. The Union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war. Proclamation of blockade and legal implications On April 19, 1861, President Lincoln issued a ''Proclamation of Blockade Against Southern Ports'': Whereas an insurrection against the Government of the United States has broken out in the States of South Carolina, Georgia, Alabama, Florida, Mississippi, Louisian ...

Columbia, South Carolina In The American Civil War
Columbia, the capital city of South Carolina, was an important political and supply center for the Confederate States Army during the American Civil War. Much of the town was destroyed during occupation by Union forces under Major General William T. Sherman during the Carolinas Campaign in the last months of the war. Sherman was accused of having deliberately and needlessly burned the city, which he denied. Modern historians say that multiple causes were responsible. Early Civil War history Columbia became chartered as a city in 1786 and soon grew at a rapid pace, and throughout the 1850s and 1860s it was the largest inland city in the Carolinas. Railroad transportation served as a significant cause of population expansion in Columbia during this time. Rail lines that reached the city in the 1840s were first and foremost interested in transporting cotton bales, not passengers. Cotton was the lifeblood of the Columbia community, as before the Civil War, directly or indirectly, vir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
