In 1887, a false rumor that gold had been discovered in an area then known as the Trap Mountains resulted in a brief gold rush, which ended when the rumor proved false. Shortly after 1900, the Gurdon and Fort Smith Railroad was constructed through Amity, greatly improving the economy of the town. Soon, the logging industry began to thrive, with large sawmills opening in Rosboro and Glenwood. Amity became a main shipping and trade center for the area, and in 1905 the Bank of Amity opened, which now is on the National Register of Historic Places. In 1899 the town's first newspaper, the "Amity Enterprise", went into circulation, followed by the "Four-County Courier" in 1915 and the "Amity Owl" in 1922. Just before World War II, the shortage of cinnabar caused a brief but productive mining industry in the nearby mountains south of the town, a phenomenon which became known as the Quicksilver Rush. However, any significant mining had ended by 1940, and following the war and an increased worldwide supply, the mines closed.
