Hitchcock became assistant to his father on the geological survey of Vermont (1857-61), and during the same period pursued theological studies at Yale for a year and at Andover Seminary for two years, with a view to entering the ministry. His geological field work seems, however, to have diverted his taste to another calling, and in 1861 he was appointed state geologist of Maine. From 1858 to 1866 he served also as curator of the museum at Amherst, and was lecturer on zool- ogy, 1858-64. He was non-resident lecturer for Lafayette College, Pennsylvania, from 1866 to 1870, and in the decade 1860-70 served also in a private capacity as an expert for various min- ing interests in the Eastern states. During the year 1866-67 he studied at the Royal School of Mines in London and traveled in Europe, re- turning to receive the appointments of state geologist of New Hampshire (1868) and pro- fessor of geology and mineralogy at Dartmouth College. Facilities for detailed geological work in Maine were not such as to promote results of consequence, and it was not until the survey of New Hampshire was undertaken that Hitchcock had a reasonable opportunity to display his abil- ities as an administrator and geologist. This survey continued for ten years, or until 1878; and its results were given to the public—aside from the brief annual reports—in three quarto volumes, The Geology of New Hampshire (1874-78). The glacial geology of the state nat- urally received much attention. For a part of each year from 1870 to 1896 Hitchcock was lec- turer on geology at Mount Holyoke. In 1908, after forty years at Dartmouth, he retired as professor emeritus and took up his residence in Honolulu, H. I., devoting his attention thence- forth mainly to volcanic problems. His last pub- lication, Hawaii and its Volcanoes, a volume of 314 pages with fifty plates, was issued in 1909. He died at Honolulu ten years later, having nearly reached the age of eighty-three. Hitchcock was married, June 19, 1862, to Martha Bliss Barrows of Andover, Mass., who died in February 1892, leaving him two sons and three daughters, On Sept. 4,1894, he mar- ried Charlotte Malvina Barrows, a sister of his first wife.

His ancestry was English: the first of the family, Matthias Hitchcock, came from London to Boston on the bark Susan and Ellen in May 1635 and settled in East Haven, Conn., after a short stay in Watertown, Mass. Justin, the father of Edward, was fifth in line of descent from Luke Hitchcock, brother of Matthias, who took the freeman's oath in New Haven in July 1644 and afterward settled in Wethersfield. The family was in moderate circumstances and Ed- ward was to a large extent thrown upon his own resources and those of the public school for his education. Early developing scholastic tenden- cies, with a fondness for natural history and mathematics, he first attracted more than local notice through his discovery of numerous errors, which he corrected, in Blunt's Nautical Almanac. Between the ages of twenty-two and twenty-six he was principal of the Deerfield Academy, and through the influence of Amos Eaton [#.z>.], then a free-lance lecturer, he became interested in botany and mineralogy. Choosing the ministry for his profession, he entered the theological school at New Haven. Here he was thrown in association with Prof. Benjamin SilHman [#.£>.], with whom he formed a life-long friendship. From 1821 to 1825 he was settled over the Con- gregational church in Conway, Mass., and in the last-named year was at his own request dis- missed on account of poor health and appointed professor of chemistry and natural history in Amherst College. Twenty years later he became president of the college, holding that office for ten years and then resigning to assume a pro- fessorship of geology and natural theology. Through Hitchcock's efforts there was estab- lished in 1830 a geological survey of the state of Massachusetts, of which he was made the head. The work was continued for three years and was the first of its kind in America to be carried to completion. Its results were pub- lished in Report on the Geology, Mineralogy, Botany, and Zoology of Massachusetts (1833). In 1837 Hitchcock undertook a renewal of the survey under state auspices, bringing the work to completion in 1841 (Final Report on the Geol- ogy of Massachusetts, 2 vols., 1841). Mean- while, in 1836 he had been appointed geologist of the first district of the newly organized sur- vey of New York, but he resigned because the duties of the position were too heavy in addition to those he was already carrying. The matter which first brought him into public notice was the discovery made by James Deane and others of enormous birdlike track$ in the red sand-
