Oriental Powder Company was a gunpowder manufacturer with mills located on the Presumpscot River in Gorham and Windham, Maine. The company was one of the four largest suppliers to Union forces through the American Civil War.
The Presumpscot River dropped 16 feet at Gambo Falls where the river formed the border between the towns of Windham and Gorham. Sebago Lake formed a large natural reservoir upstream of Gambo giving the falls an unusually reliable water supply with comparatively minor flow peaking from storm runoff. [1] Early European settlers built a sawmill powered by the falls. In 1824 the sawmill was converted to a powder mill by Edmund Fowler and Lester Laflin. Their Gorham Powder Company became known among the local population as the Gambo powder mills. [2] Lester Laflin was a grandson of American Revolutionary War gunpowder manufacturer Matthew Laflin. The Laflin family manufactured gunpowder in Massachusetts for several generations. When Lester came east to Maine, his first cousins traveled west to build gunpowder mills in New York and Chicago. [3] Lester, his partner, and their mill foreman drowned on Sebago Lake on 22 June 1827. [4] Following an explosion killing seven employees on 19 July 1828, [5] the Gambo Falls mill was enlarged by Oliver Whipple concurrently with construction of locks for the Cumberland and Oxford Canal. Whipple had been manufacturing gunpowder in Lowell, Massachusetts since 1818. The new canal provided reliable transportation from Portland harbor for sulfur from Sicily and saltpeter from India and from Sebago Lake for charcoal and lumber from forests to the north. Whipple's Gambo mill used the lumber to manufacture kegs holding as much as 25 pounds of powder. Kegs of gunpowder were shipped to Portland in canal boats when possible, but moved in horse-drawn sleighs when the canal was frozen. [4] Canal boats carried about 25 tons, and sometimes sailed all the way to Boston when weather was favorable. [5]
After plant explosions killed one employee each in 1835, 1847, 1849, 1850, and 1851, a major explosion on 12 October 1855 killed seven employees, [5] including Whipple's brother and son, injured five more and destroyed a canal boat and parts of the mill. [4] Manufacture of gunpowder in response to orders avoided the hazard of storing powder inventories until orders were received, but required water power on demand. The canal lock system controlled outflow from Sebago Lake; and, as a shipper interested in the well-being of its customer, canal management was receptive to regulating water releases to meet needs of the powder mill.
Gilbert Grafton Newhall of Salem, Massachusetts, [6] purchased the property in early 1855 to manufacture powder for Crimean War belligerents, and organized Oriental Powder Company to repair the damage and construct new facilities. A charcoal house, saltpeter refinery, wheel mills, press mills, kernelling mills, glazing mills, and storehouses were dispersed along both banks of the river and canal for a mile upstream of Gambo to minimize damage during infrequent explosions. [7] Charcoal was manufactured from dried, debarked alder packed into cast iron retorts. Charcoal was made from willow, poplar or maple when alder was unavailable. Crude saltpeter was dissolved in hot water in kettles holding as much as 600 U.S. gallons (2,300 L). Impurities were skimmed from the surface or settled to the bottom so a hot, saturated solution could be decanted for crystallization. Moist saltpeter crystals were mixed with appropriate amounts of sulfur and charcoal by heavy rotating wheels to form a cake which was then cut unto smaller pieces in bronze- or zinc-toothed kernelling mills. The kernels were sieved into desired sizes and dried prior to being tumbled with graphite which reduced tendency for the finished grains to stick together during storage. Intermediate products were transported between the dispersed production and storage facilities in wooden wheelbarrows constructed with no iron parts and pushed over plank walkways by workmen going barefoot in the summer or wearing shoes without iron nails during colder weather. [8] Newhall gave his name to a small company town of employee residences built near Gambo Falls. [4] Company offices were in Portland, Maine to avoid business disruption by the periodic explosions at the manufacturing facilities. [9]
By 1860, Oriental was one of four companies making 69% of United States gunpowder sales. The larger DuPont and Hazard Powder Company mills each provided approximately one-third of the Union gunpowder supply for the civil war. [10] The fourth major supplier was Lester Laflin's cousins' mill which later evolved into the early smokeless powder manufacturer Laflin & Rand. [3] The DuPont mill was uncomfortably close to the battle line and considered potentially vulnerable to sabotage from southern sympathizers in the slave state of Delaware. [11]
The federal government purchased as much powder as Oriental Powder Company could produce through the war years. Wartime production included large cast hexagonal powder grains for Rodman guns; and an 8-inch (20 cm) Columbiad was installed at Gambo to test this specialized powder. Production increased to 1250 tons per year [8] as accidental explosions killed one employee on 8 July 1861, three on 7 July 1862, and another on 14 November 1863. [5] Demand for gunpowder declined when the civil war ended, but picked up briefly during the Franco-Prussian War [12] and Russo-Turkish War. [8] Oriental Powder Company was ranked 4th (after DuPont, Laflin & Rand, and Hazard) among the six companies of the United States Gunpowder Trade Association popularly known as the powder trust. [13]
Canal boats were unable to compete with rail service and the canal was unused after the Portland and Ogdensburg Railway reached Gambo Falls (by then called Newhall) in 1871. [5] Oriental Powder Company employees assumed control of the former canal dam at Sebago Lake when the canal locks ceased operations; but water users in Westbrook, Maine, were unsatisfied with timing of water releases. Court action was initiated in January 1877, following a drought. Legal maneuvering continued for several months between Oriental Powder Company and Westbrook water users while water releases were controlled by whichever side mustered a larger number of employees at the dam. Legislation enacted in February 1878 effectively passed control of water releases from Sebago Lake to water users in Westbrook. [14]
As smaller Maine gunpowder mills went out of business following the civil war, Oriental Powder Company acquired the assets of the North Buckfield Powder Mill in 1880, the Warren Powder Mill in 1887, and the Camden Powder Mill in 1892. Machinery was salvaged from these mills, and a subsidiary Oriental Powder Company of Pennsylvania began manufacturing rock blasting powder at Fairchance, Pennsylvania in 1902. [8] As telegraph became available for sales communications, the powder company reduced the risk to manufacturing facilities by building magazines for powder inventories near distant rail distribution centers like Chicago [15] and Salt Lake City. [16]
Local supplies of charcoal and keg staves became more expensive as forest resources were exhausted. The rock blasting powder market for mining and railroad construction fluctuated with financial panics. The Newhall mill ceased operations on 1 June 1893 as smokeless powder and dynamite became preferred for traditional uses of gunpowder. Eastern Dynamite Company was formed in 1895 and began manufacturing dynamite at Newhall. [8] Four employees died in three fatal explosions through the final decade of explosives manufacture. March 19, 1904, was the last of 32 recorded blasts claiming 46 lives along the river. [5] Mill operations after the 1904 explosion were limited to manufacturing wood flour shipped elsewhere for mixing with nitroglycerine to form dynamite. Production of wood flour continued into the 1950s after ownership passed to the Atlas Powder Company in 1912. [17] The civil war Columbiad remained at Newhall until scrapped during World War II. [8]
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon, and potassium nitrate (saltpetre). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines, tunnels, and roads.
Westbrook is a city in Cumberland County, Maine, United States and a suburb of Portland. The population was 20,400 at the 2020 census, making it the fastest-growing city in Maine between 2010 and 2020. It is part of the Portland–South Portland–Biddeford, Maine metropolitan statistical area.
Windham is a town in Cumberland County, Maine, United States. The population was 18,434 at the 2020 census. It includes the villages of South Windham and North Windham. It is part of the Portland–South Portland–Biddeford, Maine Metropolitan Statistical Area.
Sebago Lake (Sih-Bay-Goh) is the deepest and second-largest lake in the U.S. state of Maine. The lake is 316 feet (96 m) deep at its deepest point, with a mean depth of 101 feet (31 m). It is possible that Sebago is the deepest lake wholly contained within the entire New England region, although some sources say that Vermont's Lake Willoughby is slightly deeper. Along with Lake Champlain, Sebago is one of the only lakes in the area that does not consistently freeze solid during the winter months, with total ice cover only occurring for a short period of time every few winters. Sebago covers about 45 square miles (117 km2) in surface area, has a length of 14 miles (23 km) and has a shoreline length of roughly 105 miles (169 km). The surface is around 270 feet (82 m) above sea level, so the deep bottom is below the present sea level. It is in Cumberland County, and bordered by the towns of Casco, Naples, Raymond, Sebago, Standish and Windham. The seasonally occupied town of Frye Island is on an island in the lake. Sebago Lake and the surrounding area is known for its erratic and sudden changes in weather during all seasons, likely due to its proximity to the Atlantic Ocean and to Mt. Washington, a very notorious extreme weather hotspot. The name comes from the Abenaki sobagoo, meaning "it is the sea" or "it resembles the sea".
The Confederate Powderworks was a gunpowder factory during the American Civil War, the only permanent structures completed by the Confederate States of America. Colonel George Washington Rains chose the old United States Arsenal site between the Augusta Canal and Savannah River in Augusta, Georgia, as a secure inland location with good rail and water connections.
The Presumpscot River is a 25.8-mile-long (41.5 km) river located in Cumberland County, Maine, United States. It is the main outlet of Sebago Lake. The river provided an early transportation corridor with reliable water power for industrial development of the city of Westbrook and the village of South Windham.
From 1802 to 1921, Eleutherian Mills was a gunpowder mill site used for the manufacture of explosives founded by Eleuthère Irénée du Pont, which grew into the DuPont company. The name also refers to the house on the hill above the mills, which was the first du Pont family home in America. In 1957 the site became an outdoor museum when the Hagley Museum and Library was founded. The site was declared a National Historic Landmark in 1966.
The Cumberland and Oxford Canal was opened in 1832 to connect the largest lakes of southern Maine with the seaport of Portland, Maine. The canal followed the Presumpscot River from Sebago Lake through the towns of Standish, Windham, Gorham, and Westbrook. The Canal diverged from the river at Westbrook to reach the navigable Fore River estuary and Portland Harbor. The canal required 27 locks to reach Sebago Lake at an elevation of 267 feet (81 m) above sea level. One additional lock was constructed in the Songo River to provide 5 feet (1.5 m) of additional elevation to reach Long Lake from Sebago Lake. Total navigable distance was approximately 38 miles (61 km) from Portland to Harrison at the north end of Long Lake. A proposed extension from Harrison to Bear Pond and Tom Pond in Waterford would have required three more locks on the Bear River, but they were never built.
The Mountain Division is a railroad line that was once owned and operated by the Maine Central Railroad (MEC). It stretches from Portland, Maine on the Atlantic Ocean, through the Western Maine Mountains and White Mountains of New Hampshire, ending at St. Johnsbury, Vermont in the Northeast Kingdom. The line was abandoned in 1983 by MEC's successor, Guilford Transportation Industries (GTI). Guilford retained a stub between Portland and Westbrook. A section in New Hampshire remains in use by heritage railway Conway Scenic Railroad.
A powder mill was a mill where gunpowder is made from sulfur, saltpeter and charcoal.
The Wamesit Canal-Whipple Mill Industrial Complex is a historic mill and canal at 576 Lawrence Street in Lowell, Massachusetts. This industrial area of Lowell, located on the Concord River, underwent a major expansion from a more modest millworks in the mid-19th century by Oliver Whipple, a manufacturer of gunpowder.
South Windham is a census-designated place (CDP) in the town of Windham in Cumberland County, Maine, United States. The population of the CDP was 1,374 at the 2010 census. Prior to 2010, South Windham was part of the Little Falls-South Windham census-designated place.
The Pleasant River is a 13.1-mile-long (21.1 km) tributary of the Presumpscot River in the U.S. state of Maine.
The Hazard Powder Company is a former American manufacturer of gunpowder and explosives. It was located in Hazardville within the town of Enfield, Connecticut.
California Powder Works was the first American explosive powder manufacturing company west of the Rocky Mountains. When the outbreak of the Civil War cut off supplies of gunpowder to California's mining and road-building industries, a local manufacturer was needed. Originally located near Santa Cruz, California, the company was incorporated in 1861 and began manufacturing gunpowder in May 1864. For 50 years, it was a major employer in the county, employing between 150 and 275 men. The powder works was located on a flat adjacent to the San Lorenzo River, three miles upstream of Santa Cruz.
Laflin & Rand Powder Company was a gunpowder and early smokeless powder manufacturer notable for producing the smokeless powder used by United States Army infantry rifles from 1896 to 1908, which included the period of development of the M1903 Springfield rifle and .30-06 Springfield cartridge.
Gorham is a town in Cumberland County, Maine, United States. The population was 18,336 at the 2020 United States Census. In addition to its urban village center known as Gorham Village or simply "the Village," the town encompasses a number of smaller, unincorporated villages and hamlets with distinct historical identities, including South Gorham, West Gorham, Little Falls, White Rock, and North Gorham. Gorham is home to one of the three campuses of the University of Southern Maine. In 2013, Gorham was voted second-best town in Maine after Hampden by a financial website.
American Powder Mills (1883–1929) was a Massachusetts gunpowder manufacturing complex on the Assabet River. It expanded to include forty buildings along both sides of the river in the towns of Acton, Concord, Maynard, and Sudbury. Press mills, kernelling mills, glazing mills, and storehouses were dispersed over four-hundred acres to minimize damage during explosions. A narrow gauge railway transferred raw materials and products between the buildings.
Miami Powder Company operated a gunpowder manufacturing complex on the Little Miami River at Goes Station, Ohio from 1855 to 1925. Willows growing along the banks of the Little Miami River provided the charcoal required for gunpowder. Production was approximately 75 percent rifle powder and 25 percent blasting powder.
The Great Falls Historic District encompasses the remains of an early 19th-century mill hamlet in Windham, Maine. On the east bank of the Presumpscot River north of Windham Center Road are a cluster of three houses from the period, as well as the archaeological remains of a few mills that lined the river at the falls just north of the road. The district was listed on the National Register of Historic Places in 1995.
