Moses Carver (29 August 1812 – 19 December 1910) was an American settler and adoptive father of George Washington Carver , his former slave .
102-501: Moses Carver was born in Dayton, Ohio . On August 11, 1834, he married Susan Blue in Springfield, Illinois . He and his brother Richard migrated to southwest Missouri around 1838 from Ohio and Illinois. The Preemption Act of 1841 allowed farmers who lived on and improved 160 acres (0.65 km) of land for six months to buy the land from the government at a low price. Moses Carver purchased
204-534: A caisson of water in which boats float while being moved between two levels; and inclined planes where a caisson is hauled up a steep railway. To cross a stream, road or valley (where the delay caused by a flight of locks at either side would be unacceptable) the valley can be spanned by a navigable aqueduct – a famous example in Wales is the Pontcysyllte Aqueduct (now a UNESCO World Heritage Site ) across
306-504: A drainage divide atop a ridge , generally requiring an external water source above the highest elevation . The best-known example of such a canal is the Panama Canal . Many canals have been built at elevations, above valleys and other waterways. Canals with sources of water at a higher level can deliver water to a destination such as a city where water is needed. The Roman Empire 's aqueducts were such water supply canals. The term
408-572: A tornado outbreak , in which a total of 15 tornadoes touched down in the Dayton area. Although some of the tornadoes were only EF0 and remained on the ground for less than a mile, one was an EF4 measuring a half-mile-wide (805 meters), which tore through the communities of Brookville, Trotwood, Dayton, Northridge, and Riverside. Several streets were closed, including portions of I-75 and North Dixie Drive in Northridge. 64,000 residents lost power and much of
510-415: A "cistern", or depressed area just downstream from the fall, to "cushion" the water by providing a deep pool for its kinetic energy to be diffused in. Vertical falls work for drops of up to 1.5 m in height, and for discharge of up to 15 cubic meters per second. The transport capacity of pack animals and carts is limited. A mule can carry an eighth-ton [250 pounds (113 kg)] maximum load over
612-477: A "peace chain," although it was not large enough to surround the sprawling eight-thousand-acre base. Ohio's famous ethnic diversity was on display. Downtown expansion that began in the 2000s has helped revitalize the city and encourage growth. Day Air Ballpark , home of the Dayton Dragons , was built in 2000. The highly successful minor league baseball team has been an integral part of Dayton's culture. In 2001,
714-496: A canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as slack water levels , often just called levels . A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin , and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley . A canal can cut across
816-413: A combination of the three, depending on available water and available path: Smaller transportation canals can carry barges or narrowboats , while ship canals allow seagoing ships to travel to an inland port (e.g., Manchester Ship Canal ), or from one sea or ocean to another (e.g., Caledonian Canal , Panama Canal ). At their simplest, canals consist of a trench filled with water. Depending on
918-543: A journey measured in days and weeks, though much more for shorter distances and periods with appropriate rest. Besides, carts need roads. Transport over water is much more efficient and cost-effective for large cargoes. The oldest known canals were irrigation canals, built in Mesopotamia c. 4000 BC , in what is now Iraq . The Indus Valley civilization of ancient India ( c. 3000 BC ) had sophisticated irrigation and storage systems developed, including
1020-436: A male householder with no spouse present, and 38.2% had a female householder with no spouse present. 47.4% of all households were made up of individuals, and 14.6% were someone living alone who was 65 years of age or older. The average household size was 1.95, and the average family size was 2.83. 18.9% of the city's population were under the age of 18, 65.0% were 18 to 64, and 16.1% were 65 years of age or older. The median age
1122-617: A new location was sought. The Patterson family formed the Dayton Air Service Committee, Inc which held a campaign that raised $ 425,000 in two days and purchased 4,520.47 acres (18.2937 km ) northeast of Dayton, including Wilbur Wright Field and the Huffman Prairie Flying Field. Wright Field was "formally dedicated" on October 12, 1927. After World War II, Wright Field and the adjacent Patterson Field, Dayton Army Air Field, and Clinton Army Air Field were merged as

Eight other presidents have visited the courthouse, either as presidents or during presidential campaigns: Andrew Johnson , James Garfield , John F. Kennedy , Lyndon B. Johnson , Richard Nixon , Gerald Ford , Ronald Reagan , and Bill Clinton . The Dayton Arcade , which opened on March 3, 1904,
1326-575: A rather low gradient for its time. The canal is still in use after renovation. In the Middle Ages , water transport was several times cheaper and faster than transport overland. Overland transport by animal drawn conveyances was used around settled areas, but unimproved roads required pack animal trains, usually of mules to carry any degree of mass, and while a mule could carry an eighth ton, it also needed teamsters to tend it and one man could only tend perhaps five mules, meaning overland bulk transport
1428-620: A role in a nickname given to the state of Ohio, "Birthplace of Aviation." Dayton is the hometown of the Wright brothers , aviation pioneers who are credited with inventing and building the first practical airplane in history. After their first manned flights in Kitty Hawk, North Carolina , which they had chosen due to its ideal weather and climate conditions, the Wrights returned to Dayton and continued testing at nearby Huffman Prairie . Additionally, Dayton
1530-458: A total of 240 acres (0.97 km) in Marion Township, Newton County, Missouri . As an early settler in the area, Carver selected a good site with an abundant water supply. He built a one-room log cabin with a window, a fireplace, and no floor. This is where he and Susan initially lived, along with three nieces and nephews, whom they raised after Richard's death in 1839. Moses needed help as
1632-453: A uniform altitude. Other, generally later, canals took more direct routes requiring the use of various methods to deal with the change in level. Canals have various features to tackle the problem of water supply. In cases, like the Suez Canal, the canal is open to the sea. Where the canal is not at sea level, a number of approaches have been adopted. Taking water from existing rivers or springs
1734-422: Is a channel that cuts across a drainage divide , making a navigable channel connecting two different drainage basins . Both navigations and canals use engineered structures to improve navigation: Since they cut across drainage divides, canals are more difficult to construct and often need additional improvements, like viaducts and aqueducts to bridge waters over streams and roads, and ways to keep water in
1836-442: Is also a large area that encompasses several neighborhoods itself and has seen a recent uplift and revival. Dayton's suburbs with a population of 10,000 or more include Beavercreek , Centerville , Clayton , Englewood , Fairborn , Harrison Township , Huber Heights , Kettering , Miami Township , Miamisburg , Oakwood , Riverside , Springboro , Trotwood , Vandalia , Washington Township , West Carrollton , and Xenia .

The Moses Carver farm became the George Washington Carver National Monument by an act of Congress in July 1943. The National Park Service maintains 210 acres (0.85 km) of the original 240-acre (0.97 km) farm. In 2004 the remaining 30 acres of the original Moses Carver Farm were donated to the George Washington Carver Birthplace District Association by Evelyn Taylor and her late husband W.J. "Bud" Taylor. The Association later donated

A canal fall is constructed by cut and fill . It may be combined with a regulator, bridge, or other structure to save costs. There are various types of canal falls, based on their shape. One type is the ogee fall, where
2652-532: Is still in existence. In 1797, Daniel C. Cooper laid out Mad River Road , the first overland connection between Cincinnati and Dayton, opening the "Mad River Country" to settlement. Ohio was admitted into the Union in 1803, and the village of Dayton was incorporated in 1805 and chartered as a city in 1841. The city was named after Jonathan Dayton , a captain in the American Revolutionary War who signed

The Naviglio Grande is the most important of the lombard " navigli " and the oldest functioning canal in Europe. Later, canals were built in the Netherlands and Flanders to drain the polders and assist transportation of goods and people. Canal building was revived in this age because of commercial expansion from
3672-532: The Phoenix metropolitan area was the most complex in ancient North America. A portion of the ancient canals has been renovated for the Salt River Project and now helps to supply the city's water. The Sinhalese constructed the 87 km (54 mi) Yodha Ela in 459 A.D. as a part of their extensive irrigation network which functioned in a way of a moving reservoir due to its single banking aspect to manage
3774-522: The River Brue at Northover with Glastonbury Abbey , a distance of about 1.75 kilometres (1,900 yd). Its initial purpose is believed to be the transport of building stone for the abbey, but later it was used for delivering produce, including grain, wine and fish, from the abbey's outlying properties. It remained in use until at least the 14th century, but possibly as late as the mid-16th century. More lasting and of more economic impact were canals like

When this is done with clay, it is known as puddling . Canals need to be level, and while small irregularities in the lie of the land can be dealt with through cuttings and embankments, for larger deviations other approaches have been adopted. The most common
4386-466: The 12th century. River navigations were improved progressively by the use of single, or flash locks . Taking boats through these used large amounts of water leading to conflicts with watermill owners and to correct this, the pound or chamber lock first appeared, in the 10th century in China and in Europe in 1373 in Vreeswijk , Netherlands. Another important development was the mitre gate , which was, it

The main reason for the broad streets was that Dayton was a marketing and shipping center from its beginning; streets were broad to enable wagons drawn by teams of three to four pairs of oxen to turn around. Also, some of today's streets were once barge canals flanked by draw-paths. A courthouse building was built in downtown Dayton in 1888 to supplement Dayton's original Neoclassical courthouse, which still stands. This second, "new" courthouse has since been replaced with new facilities as well as
6630-399: The drop follows an s-shaped curve to create a smooth transition and reduce turbulence . However, this smooth transition does not dissipate the water's kinetic energy, which leads to heavy scouring. As a result, the canal needs to be reinforced with concrete or masonry to protect it from eroding. Another type of canal fall is the vertical fall, which is "simple and economical". These feature

Orville and Wilbur Wright were the first to construct and demonstrate powered flight. Although the first flight was in Kitty Hawk, North Carolina , their Wright Flyer was built in and returned to Dayton for improvements and further flights at Huffman Field , a cow pasture eight miles (13 km) northeast of Dayton, near
7548-510: The late 20th century, Dayton's businesses have diversified into a service economy . Ohio's borders are within 500 miles (800 km) of roughly 60 percent of the country's population and manufacturing infrastructure, making Dayton a logistics hub. The city is home to Wright-Patterson Air Force Base , a significant contributor to research and development in the industrial, aeronautical , and astronautical engineering fields. Along with defense and aerospace, healthcare accounts for much of

Clark referring to transport realities before the industrial revolution and the Canal age . Hohokam was a society in the North American Southwest in what is now part of Arizona , United States, and Sonora , Mexico. Their irrigation systems supported the largest population in
7752-472: The longest canal in the world today and the oldest extant one. It is 1,794 kilometres (1,115 mi) long and was built to carry the Emperor Yang Guang between Zhuodu ( Beijing ) and Yuhang ( Hangzhou ). The project began in 605 and was completed in 609, although much of the work combined older canals, the oldest section of the canal existing since at least 486 BC. Even in its narrowest urban sections it
7854-523: The longest one of that period being the Hong Gou (Canal of the Wild Geese), which according to the ancient historian Sima Qian connected the old states of Song, Zhang, Chen, Cai, Cao, and Wei. The Caoyun System of canals was essential for imperial taxation, which was largely assessed in kind and involved enormous shipments of rice and other grains. By far the longest canal was the Grand Canal of China , still
7956-426: The nationwide King assassination riots . Since the 1980s, however, Dayton's population has declined, mainly due to the loss of manufacturing jobs and decentralization of metropolitan areas, as well as the national housing crisis that began in 2008. While much of the state has suffered for similar reasons, the impact on Dayton has been greater than most. Dayton had the third-greatest percentage loss of population in
8058-506: The numbers that once fueled and enabled economic growth, indeed were practically a prerequisite to further urbanization and industrialization. For the movement of bulk raw materials such as coal and ores are difficult and marginally affordable without water transport. Such raw materials fueled the industrial developments and new metallurgy resulting of the spiral of increasing mechanization during 17th–20th century, leading to new research disciplines, new industries and economies of scale, raising
8160-408: The overall trend leaning towards growth for the metro area. The city's most populous ethnic group, white, declined from 78.1% in 1960 to 51.7% by 2010. As of the census of 2020, there were 137,644 people living in the city, for a population density of 2,466.47 people per square mile (952.31/km ). There were 68,899 housing units.

There were 58,404 households, of which 28.3% had children under the age of 18 living with them, 25.9% were married couples living together, 21.4% had a female householder with no husband present, 5.9% had a male householder with no wife present, and 46.8% were non-families. 38.8% of all households were made up of individuals, and 11.2% had someone living alone who was 65 years of age or older. The average household size
8466-582: The pre-railroad days of the industrial revolution, water transport was the gold standard of fast transportation. The first artificial canal in Western Europe was the Fossa Carolina built at the end of the 8th century under personal supervision of Charlemagne . In Britain, the Glastonbury Canal is believed to be the first post-Roman canal and was built in the middle of the 10th century to link
8568-534: The region's water supply was cut off. The Dayton Audubon Society is the National Audubon Society 's local chapter. The Dayton chapter manages local activities contributing to the annual, hemisphere-wide Christmas Bird Count . The Chapter began participation in the National Count in 1924. The local Count was initially coordinated by Ben Blincoe, who was succeeded by Jim Hill in 1970. In the mid-1960s,
8670-574: The region, much of which is still in use today. Alan Turing is widely considered to be the father of theoretical computer science and artificial intelligence. He visited the National Cash Register (NCR) company in Dayton in December 1942. He was able to show that it was not necessary to build 336 Bombes , so the initial order was scaled down to 96 machines to decipher German Enigma-machine-encrypted secret messages during World War II. Between
8772-480: The standard of living for any industrialized society. Most ship canals today primarily service bulk cargo and large ship transportation industries, whereas the once critical smaller inland waterways conceived and engineered as boat and barge canals have largely been supplanted and filled in, abandoned and left to deteriorate, or kept in service and staffed by state employees, where dams and locks are maintained for flood control or pleasure boating. Their replacement
8874-643: The state since the 1980s, behind Cleveland and Youngstown. Despite this, Dayton has begun diversifying its workforce from manufacturing into other growing sectors such as healthcare and education. In 1995, the Dayton Agreement , a peace accord between the parties to the hostilities of the conflict in Bosnia-Herzegovina and the former Yugoslavia , was negotiated at Wright-Patterson Air Force Base , near Fairborn, Ohio, from November 1 to 21. Richard Holbrooke wrote about these events in his memoirs: There
8976-428: The story from every angle, drawing the people deeper into the proceedings. When we ventured into a restaurant or a shopping center downtown, people crowded around, saying that they were praying for us. Warren Christopher was given at least one standing ovation in a restaurant. Families on the airbase placed "candles of peace" in their front windows, and people gathered in peace vigils outside the base. One day they formed
9078-556: The valley of the River Dee . Another option for dealing with hills is to tunnel through them. An example of this approach is the Harecastle Tunnel on the Trent and Mersey Canal . Tunnels are only practical for smaller canals. Some canals attempted to keep changes in level down to a minimum. These canals known as contour canals would take longer, winding routes, along which the land was
9180-401: The war effort during World War II. Several locations around the city hosted the Dayton Project , a branch of the larger Manhattan Project , to develop polonium triggers used in early atomic bombs. The war efforts led to a manufacturing boom throughout the city, including high-demand for housing and other services. At one point, emergency housing was put into place due to a housing shortage in
9282-415: Was 2.26, and the average family size was 3.03. Canal Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation ) or for conveyancing water transport vehicles (e.g. water taxi ). They carry free, calm surface flow under atmospheric pressure , and can be thought of as artificial rivers . In most cases,
9384-422: Was 38.4. For every 100 females, there were 101.5 males. According to the U.S. Census American Community Survey , for the period 2016-2020 the estimated median annual income for a household in the city was $ 43,780, and the median income for a family was $ 60,408.

There were 63,308 households, out of which 22.1% had children under the age of 18 living with them, 24.5% were married couples living together, 30.9% had
9588-596: Was abolished in Missouri ( 1865 ), Moses and Susan continued to raise James and George on the farm. In a state strongly divided by the tensions leading to the Civil War, the independent-minded and eccentric Moses Carver was in a difficult position, since he offended Confederates by being a Unionist , and Unionists by owning slaves. George left the farm when he was eleven to go to the black school in Neosho, Missouri . He returned to
9690-469: Was also a real Dayton out there, a charming Ohio city, famous as the birthplace of the Wright brothers . Its citizens energized us from the outset. Unlike the population of, say, New York City, Geneva or Washington , which would scarcely notice another conference, Daytonians were proud to be part of history. Large signs at the commercial airport hailed Dayton as the "temporary center of international peace." The local newspapers and television stations covered
9792-466: Was also expensive, as men expect compensation in the form of wages, room and board. This was because long-haul roads were unpaved, more often than not too narrow for carts, much less wagons, and in poor condition, wending their way through forests, marshy or muddy quagmires as often as unimproved but dry footing. In that era, as today, greater cargoes, especially bulk goods and raw materials , could be transported by ship far more economically than by land; in
9894-458: Was an option in some cases, sometimes supplemented by other methods to deal with seasonal variations in flow. Where such sources were unavailable, reservoirs – either separate from the canal or built into its course – and back pumping were used to provide the required water. In other cases, water pumped from mines was used to feed the canal. In certain cases, extensive "feeder canals" were built to bring water from sources located far from
9996-552: Was built in the hopes of replacing open-air markets throughout the city. Throughout the decades, the Arcade has gone through many transformations but has retained its charm. Some of its main features include a Flemish facade at the Third Street entrance, a glass dome above the Arcade rotunda, and a chateau roof line above the Third Street facade. The Dayton Arcade is currently under renovations with no official completion date set. In 2009,
10098-463: Was gradual, beginning first in the United States in the mid-1850s where canal shipping was first augmented by, then began being replaced by using much faster , less geographically constrained & limited, and generally cheaper to maintain railways . By the early 1880s, canals which had little ability to economically compete with rail transport, were off the map. In the next couple of decades, coal
10200-424: Was increasingly diminished as the heating fuel of choice by oil, and growth of coal shipments leveled off. Later, after World War I when motor-trucks came into their own, the last small U.S. barge canals saw a steady decline in cargo ton-miles alongside many railways, the flexibility and steep slope climbing capability of lorries taking over cargo hauling increasingly as road networks were improved, and which also had
10302-426: Was once used to describe linear features seen on the surface of Mars , Martian canals , an optical illusion. A navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal
10404-478: Was originally Winters Tower, the headquarters of Winters Bank. The building was renamed after Virginia Kettering when Winters was merged into Bank One . KeyBank Tower was known as the MeadWestvaco Tower before KeyBank gained naming rights to the building in 2008. Ted Rall said in 2015 that over the last five decades Dayton has been demolishing some of its architecturally significant buildings to reduce
