Ives plore the Colorado River (1857-58). The navi- gability of the river having been ascertained by Lieut George H. Derby [q.v.~\ and George A. Johnson, Ives made a minute hydrographic sur- vey, using an iron steamer built in Philadelphia and shipped in sections via Panama and San Francisco. Leaving the unwieldy steamer at the mouth of the Black Canyon, he continued his explorations by skiff and later made a land jour- ney over the route traversed in 1776 by the mis- sionary priest Francisco Garces [g.z>.] on his march to Oraibi. The comprehensive observa- tions of Ives and the scientists accompanying his expedition were "a distinct contribution" to the knowledge of a little-known and superficially ex- plored region (Freeman,/wJ, p. 170). The vivid descriptions in Ives's interesting and valuable "Report upon the Colorado River of the West" (House Executive Document No. 90, 36 Cong., i Sess.) drew acclaim (American Journal of Science and Arts, May 1862). Ives also prepared a Memoir to Accompany a Military Map of the Peninsula of Florida, South of Tampa Bay (1856) and Military Maps of the Seat of War in Italy (1859). In 1859-60 he served as engineer and architect of the Washington national monu- ment, after which he became astronomer and sur- veyor to the commission sent to survey the bound- ary between California and the intervening United States territories (1860-61). Appointed captain in May 1861, he declined the appointment and was commissioned captain of engineers in the Confederate army. In Nov. 8, 1861, he was appointed by General Lee chief engineer of the department composed of the coasts of South Car- olina, Georgia, and East Florida. During 1861- 62 he was engaged in perfecting the defenses of Savannah and Charleston, and was promoted colonel. He then undertook the obstruction of the rivers of North Carolina (1863) and was ap- pointed aide-de-camp to President Davis (1863- 65), in which capacity he made tours of inspec- tion and investigations of the several military de- partments. In December 1864 he was sent by Davis to aid General Beauregard in the defense of the city of Charleston. After the war he lived in New York City, where he died in November 1868. [G. W. Cullum, Biog.

The Ives fam- ily soon left the ancestral farm for Turin, N. Y., Ives in the Black River country where a number of Meiiden folk had settled, and young Levi was trained in the local school and in Lowville Acad- emy until he enlisted in the War of 1812. In 1816 he registered at Hamilton College with the view of becoming a Presbyterian minister, but illness prevented his graduation. In 1819 he affiliated with the Protestant Episcopal Church and studied theology under Bishop J. H. Hobart, whose daughter, Rebecca, he married in 1822. Ordered a deacon by Bishop Hobart, Aug. 14, 1822, he was ordained priest by Bishop William White in Trinity Church, Philadelphia, June 14, 1823, and assigned to St. James' Church, Ba- tavia, N. Y. His advance was rapid: he was suc- cessively rector of Trinity Church (Southwark), Philadelphia; assistant minister in Trinity Church, New York; rector of St. James' Church, Lancaster, Pa.; and finally the bishop of North Carolina, He was consecrated bishop in 1831 at Trinity Church, Philadelphia, by Bishop White who was assisted by the Bishops H. U. and B. T. Onderdonk In his Southern diocese he infused new life into the church. He also found time to publish his New Manual of Devotions, Humility a Minis- terial Qualification (1840), The Apostle's Doc- trine and Fellowship (1844), and The Obedience of Faith (1849). The slavery question was dis- tressing to him. Despite his concern about negro education and his publication of a catechism for slaves, which did not please his fold, he was taken to task for championing slavery in an address before an Episcopalian convention in which he answered the reproof administered to the Ameri- can church by the lord bishop of Oxford (Wil- liam Jay, A Letter to the Rt. Rev. L. SiUinian Ives, 3rd ed., 1848). As a result of a study of the Protestant revolt in England, Ives was attracted by the Oxford movement and founded the Broth- erhood of the Holy Cross at Valle Crucis, N. C, which featured High-church views. In 1848, when he was arraigned before a convention of the Episcopalian Church for heterodox practices, his explanations were accepted, though the Brotherhood was dissolved (R. S. Mason, ^4 Let- ter to the Bishop of North Carolina on the Sub- ject of his late Pastoral on the Salisbury Conven- tion, 1850). But apparently the bishop's trac- tarian doubts were not silenced, for while on leave of absence, he journeyed to Rome and there came to a decision which "produced a great sen- sation." He resigned his see, Dec. 22,1852, made his submission to Pope Pius IX on Christmas day, and brought his wife into the Catholic Church. Thereupon he was officially deposed* Remaining abroad two years, he delayed his pas- 521
