Hitchcock fantry, of which he was made lieutenant-colonel in January 1842, became under his guidance one of the crack regiments of the army and the first since the War of 1812 to practise the evolution of the line. Transferred to Jefferson Barracks, St. Louis, in 1843, and to the Louisiana frontier in 1844, his regiment became a part of General Tay- lor's army of occupation in 1845. After leave of absence on account of ill health, he returned in time for the Mexican War. A reconciliation with General Scott was followed by his appointment as inspector-general on the latter's staff. At the close of the war he was promoted colonel and given command of the Military Division of the Pacific. Stationed in San Francisco, he broke up Walker's filibustering expedition into Mexico by his seizure of the brig Arrow. This act brought upon him the hostility of Secretary Davis, who refused Hitchcock's application for four months' leave of absence because of re- newed ill health. Hitchcock thereupon resigned from the army, Oct. 18, 1855. The outbreak of the Civil War found him liv- ing in St. Louis. He at once went to Washing- ton to offer his services to the Federal govern- ment, and after vexatious delays was appointed, through the influence of General Scott, major- general of volunteers. He rendered efficient aid to the War Department, becoming commissioner for exchange of prisoners of war on Nov. 15, 1862, and commissary general of prisoners of war on Nov. 3,1865. His labors were not ended until Oct. i, 1867, when he was among the last volunteers to be mustered out. In 1868 he mar- ried Martha Rind Nicholls of Washington, D. C After the War he resided in the South for the sake of his health, living first in Charleston, S. C, and then in Sparta, Ga., whither he moved shortly before his death. Hitchock's first book, The Doctrines of Spi- noza and Swedenborg Identified (1846) pointed out numerous hitherto unnoticed parallels in the philosophy of the two but somewhat overstressed their importance. In Remarks upon Alchemy and the Alchemists (1857) he endeavored to prove that the leading alchemists were members of a vast secret society devoted to symbolic pres- entation of a liberal pantheistic philosophy under the disguise of other interests. In this society he enrolled the writers of the Gospels in Christ the Spirit (1851); Swedenborg in Swedenborg a Hermetic Philosopher (1858); Shakespeare in Remarks on the Sonnets (1865, 2nd ed, en- larged, 1867); Spenser, Sidney, Drayton, and Carew in Spenser's Poem Entitled Colin Clouts Come Home Againe Explained (1865); Dante in Notes on the Vita Nuova (1866). All these Hitchcock laborious efforts are today only literary curi- osities, while Hitchcock's one really valuable literary work, his vivid autobiographical Fifty Years in Camp and Field (1909), he left unpub- lished.

HITCHCOCK, ETHAN ALLEN (Sept. 19, i83S-Apr. 9,1909), secretary of the interior, was the son of Henry and Anne (Erwin) Hitchcock, and brother of Henry Hitchcock [q.v.]. He was born in Mobile, Ala., and, following the financial difficulties and sudden death of his father after the panic of 1837, was taken by his mother to Nashville, Tenn. There he received his early education, which was supplemented by study at an academy at New Haven, Conn. In the late fifties he joined his brother Henry in St. Louis. In 1860 he went to China, entering the commis- sion business of Olyphant & Company at Hong Kong; he became a partner in 1866, and retired six years later, having amassed a fortune. He had married, Mar. 22,1869, Margaret D. Collier of St. Louis, whose sister was the wife of his brother Henry. Following several years of travel, Hitchcock returned to St. Louis, where from 1874 to 1897 his career was that of a successful man of affairs in a period of capitalistic enterprise and expan- sion. He established near St. Louis the first suc- cessful American plate-glass manufactory; he had extensive interests in iron and steel, and was a director in other corporations. By tempera- ment and by conviction a Republican, he con- tributed to the party campaign funds. During the framing of the tariff of 1890 he assisted in the preparation of the glass schedule, at the re- quest of McKinley, with whom he formed a friendship. In 1897, the President appointed him minister to Russia, with the object of utiliz- ing his experience in advancing the interests of American trade. His creditable service in the diplomatic field was terminated in December 1898, when he was named secretary of the in- terior. It was his fortune to occupy the secretaryship for a longer period than any of his predecessors and to be a leader in the conservation movement. Early in 1903, convinced that the government was being systematically robbed of valuable lands and other natural resources, he dismissed the commissioner of the General Land Office and 74
