Saugus Iron Works National Historic Site is a National Historic Site located about 10 miles (16 kilometers) northeast of Downtown Boston in Saugus, Massachusetts. It is the site of the first integrated ironworks in North America, founded by John Winthrop the Younger and in operation between 1646 and approximately 1670. It includes the reconstructed blast furnace, forge, rolling mill, shear, slitter and a quarter-ton drop hammer. The facility is powered by seven large waterwheels, some of which are rigged to work in tandem with huge wooden gears connecting them. It has a wharf to load the iron onto ocean-going vessels, as well as a large, restored 17th-century house. ==History== During the 17th century, iron was used to manufacture a number of indispensable goods, including nails, horseshoes, cookware, tools, and weapons. The production of iron required a complex manufacturing process that could only be done by an industrial enterprise. This process was not available in North America during the early years of English colonization, which meant that all iron goods had to be imported. As it took at least two months to sail to the nearest foundry, iron goods were very expensive. John Winthrop the Younger wanted to establish an iron works in the Massachusetts Bay Colony. Winthrop believed that because the colonies had a cheap and abundant supply of raw materials, an iron works in Massachusetts could produce goods that could be sold profitably in the New England and Chesapeake Colonies as well as in England itself. In 1641, Winthrop sailed to England to get the capital he needed to fund the enterprise.〔 The Company of Undertakers for the Iron Workes () in New England was founded to finance the project. Winthrop selected a site in Braintree, Massachusetts (now part of present-day Quincy, Massachusetts) as the location of the first Iron Works. Construction began in 1644 and was completed in 1645. On October 15, 1645, Winthrop secured the Undertakers an exemption from taxes and a twenty-one year monopoly on iron production from the Massachusetts General Court.〔〔 The Braintree Iron Works, however, was unsuccessful due to a lack of iron ore in the area and an inadequate supply of water to power the machinery.〔 In 1645, the Undertakers wrote to Winthrop informing him that Richard Leader, a merchant from Salehurst who was familiar with the iron making process, would replace him as manager of the Iron Works.〔 After arriving in Massachusetts, Leader reviewed the previous site survey and looked into some other locations. He selected a location in Lynn, Massachusetts (now part of present-day Saugus) on the Saugus River. The river was navigable for shallow draft vessels and could be dammed to power machinery. The surrounding forests could be used to make charcoal. Bog ore could be mined from nearby ponds, swamps, riverbeds, and bogs. Limestone, which was normally used for flux was not available and through trial and error it was found that Gabbro which could be mined in nearby Nahant would work as a flux. The new iron works, which was called Hammersmith, began operations in 1646. It consisted of a blast furnace for producing pig iron and gray iron (the later of which was poured into molds to make firebacks, pots, pans, kettles, and skillets), a forge where pig iron was refined into wrought iron and a 500-pound hammer was used to make merchant bars, which were sold to blacksmiths for manufacture into finished products, and a rolling and slitting mill where flat stock that could be used to manufacture nails, bolts, horse shoes, wagon tires, axes, saw blades, and other implements was produced.〔 At the time, it was one of the most technologically advanced iron works in the world.〔〔 Once functioning, the Iron Works ran for thirty weeks of the year and produced one ton of cast iron a day.〔 Skilled workers were brought over from England to ply their trade at the iron works. These emigrants did not fit in with the local Puritan society and often ran afoul of its laws. Many ironworkers were arrested for crimes such as drunkenness, adultery, gambling, fighting, cursing, not attending church, and wearing fine clothes.〔〔 The less experienced local men who worked at the Iron Works met with frequent and sometimes fatal accidents.〔 Another source of labor was indentured servants. Indentured servants typically worked at the Iron Works for three to seven years for little or no pay in exchange for their passage to Massachusetts and the provision of food, clothing, housing, and other necessities.〔 Following the Battle of Dunbar in 1650, Scottish prisoners of war were sent to the Iron Works to work as indentured servants for a term of 7 years.〔 The Scots mostly worked as unskilled laborers, performing tasks like chopping wood. Some learned skills such as making charcoal, blacksmithing and carpentry. Many Scots did not return home after their term was complete. Instead, they remained in Massachusetts where they started families and assimilated into Puritan society.〔 In 1650, Leader, who had encountered difficulties with the Undertakers, left the Iron Works to go into the sawmill business.〔 John Gifford and William Aubrey assumed management of the Iron Works, with Gifford serving as ironmaster and Aubrey doing the accounting.〔 Although the Iron Works produced a respectable quantity of iron, due to the high cost of labor, financial mismanagement which may have included embezzlement, and a number of lawsuits, it seldom operated at a profit.〔〔 The Iron Works closed around 1670. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Saugus Iron Works National Historic Site」の詳細全文を読む スポンサード リンク
