Catoctin Furnace is an historic iron forge located on Route 15 between Frederick and Thurmont in Catoctin Furnace, MD. ==History== Catoctin Furnace (also known as Catoctin Iron Furnace) was constructed in 1774 by four brothers Thomas, Baker, Roger and James Johnson to produce pig iron from locally mined hematite.〔(【引用サイトリンク】title=Records Relating to Pre-National Zoological Park Purchases )〕 In blast by 1776, the furnace provided ammunition (cannonballs) for the American Revolutionary War. Some sources state that it also provided cannon.〔(【引用サイトリンク】title=Catoctin Iron Furnace )〕〔(【引用サイトリンク】title=Gateway to the Mountains — Chapter 3: The Catoctin Iron Works )〕 They also state that iron from this furnace was (much later of course) used to make plates for the USS Monitor; however that is considered unlikely by researchers. The Johnson brothers owned the furnaces at the site at first collectively, and after 1793 singly, until 1811. Ultimately, three furnaces were built at the site, each named for the site. The first Catoctin Furnace was rebuilt a short distance away in 1787.〔 The second, named ''Isabella'' was built in the 1850s by Jacob Kunkel (references give dates from 1853 to 1867). It still stands, within Cunningham Falls State Park.〔(【引用サイトリンク】title=Catoctin Furnace at Cunningham Falls State Park )〕 The first two furnaces burned charcoal.〔(【引用サイトリンク】title=Catoctin Iron Furnace )〕 The third, which opened in 1873, burned coke (some sources say anthracite coal, though this would be more costly〔). The entire complex closed in 1903 (attributed to rising costs and the too-late introduction of a rail link).〔〔(【引用サイトリンク】title=Catoctin Furnace at Cunningham Falls State Park )〕〔(【引用サイトリンク】title=Civil Engineering in Maryland — Catoctin Furnace )〕 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「Catoctin Furnace」の詳細全文を読む スポンサード リンク
