Fargo's public school system consists of 11 elementary schools, 3 junior high schools, and a senior high school; privately owned are 3 Catholic schools, a Lutheran school, 3 business colleges, 2 music conservatories, and 5 trade schools. The first Protestant church services in the southern Red River Valley in North Dakota were held in Fargo, and now more than 30 denominations have churches in the city. St. Mary's Cathedral is the seat of the diocese of the Roman Catholic Church for the eastern half of North Dakota, and Fargo is likewise the seat of the North Dakota diocese of the Episcopal Church. The city's best-known musical group, the Amphion Male Chorus, composed of Fargo and Moorhead, Minn., singers, has toured nearby cities and eastern United States, giving concerts in New York and Philadelphia. Community singing is popular in Fargo, and during the summer months Island Park is the scene of outdoor concerts and singing contests. In June each year the music-minded of the Red River Valley gather in the city for the Valleyland Music Festival. The agricultural college, always prominent in the cultural life of the city, has become even more important in late years with the increased number of college lyceum programs and the growth of the community theater movement. The Little Country Theater, the outstanding players' group in the State, has become a virtual authority on community theater organization and has received favorable notice nationally. The city is named for William G. Fargo, a director of the Northern Pacific Railway and founder of the Wells-Fargo Express Company, and its early history is closely linked with that of the railroad. In 1871 the announcement that a railroad would be built "from Lake Superior to the Pacific Ocean" aroused much speculation as to where it would cross the Red River, and the untouched land along the river suddenly became populated. Three settlers, Jacob Lowell, Jr., Henry S. Back, and Andrew McHench, formed a triumvirate and patrolled the Red from the mouth of the Wild Rice to the Elm River from April to June 29 in an effort to discover "the first indications of the railroad crossing."
