Task: Question Answering
Input (English): Passage: Monte Ne was entirely conceived and funded by William "Coin" Hope Harvey, a well-known businessman, politician, lecturer and author during the 1890s. Although Harvey was financially successful at silver mining in Colorado, Monte Ne seems to have been funded mostly by the sales of Harvey's writings which dealt with the subject of free silver. His most popular pamphlet, entitled Coin's Financial School, was published in 1893. Sales were buoyed by Harvey's involvement in the 1896 presidential campaign of William Jennings Bryan, and it sold two million copies. Though Bryan lost his bid for President, Harvey had become so important to the campaign that he was made chairman of the Democratic Ways & Means Committee to collect money for the 1900 campaign. However, as a result of an argument before the campaign, he resigned.After Bryan lost his bid for President, Harvey retreated to the Ozark mountains of Northwest Arkansas. In October 1900 he purchased 320 acres (130 ha) of land in Silver Springs (close to present day Rogers) from Reverend Bailey. From that time on he lived in Arkansas, and claimed that he preferred the state because it had no large cities or extremely wealthy people. Leaving his family behind in Chicago, Harvey moved into Reverend Bailey's run-down log house. Harvey's son Tom joined him shortly thereafter to help prepare the house for the rest of the family. They were joined later by Harvey's wife Anna and their children, Annette and Hal. The house burned down a few months after they took up residence, and all of the family's possessions, including Harvey's large library, were lost. Harvey carried no insurance on the house, and after its destruction Anna went back to Chicago, returning to Arkansas only a few times thereafter for brief visits.Harvey's land purchase in Silver Springs coincided with a desire by the local postmaster to change the name of the area, because it was often confused with Siloam Springs, Arkansas. Harvey chose the name Monte Ne, which supposedly combined the Spanish and Omaha Indian words for mountain water,  because it "fit the tongue attractively". Harvey was familiar with European health spas, and wanted to turn Monte Ne into a "watering hole" in the Ozarks. He first commissioned the dredging of a canal, and Silver Springs Creek was narrowed between Big Spring and Elixir Spring, which created Big Spring Lake. The Creek was then channeled to form what Harvey referred to as "the lagoon". Limestone retaining walls were built along the banks of the creeks and the lake, and along boardwalks and park areas. Monte Ne quickly became a popular spot for pleasure boating, picnics, and other outdoor activities. Many people noted how clear the water was. The Rogers Democrat said that it looked "like pure alcohol".
