DOTON, Hosea, educator, born in Pomfret, Vermont, 29 November 1809; died in Woodstock, Vermont, 19 January 1886. After receiving a common school education, he studied by himself, and became one of the best mathematicians in the state. He taught at various places till 1850, when he opened a normal school in his native town, and continued it till 1866. Fully 150 of Mr. Doton's pupils became successful teachers, and his school was a great aid to the educational system of the state. He also worked as a surveyor, and from 1866 till his death was chief engineer of the Woodstock railroad. His work in determining the altitudes of Vermont mountains is accepted as authority. He made astronomical calculations for the "Vermont Register," and for eighteen years kept a meteorological record, making full monthly reports to the war department at Washington. He was a member of the state senate in 1865'6, and in the latter year the legislature established his method of computing interest, known as the " Vermont rule." Mr. Doton received the degree of M.
