Hitchcock stone of the Connecticut Valley. Deane sent these tracks to Hitchcock and thus started a se- ries of investigations in which Hitchcock al- ways remained the dominant figure. The tracks, while strongly resembling those of birds, were after years of study by the highest authorities of the day ascribed to a dinosauric origin. Hitchcock was the first chairman (1840) of the Association of American Geologists and Naturalists which in 1847 became the American Association for the Advancement of Science. In 1856, while continuing his connection with the college at Amherst, he assumed the proffered position of state geologist of Vermont, and in 1861 presented his completed Report on the Geol- ogy of Vermont in the form of two quarto vol- umes, with thirty-six full-page plates and a geo- logical map. One of the observations of this survey which excited considerable interest at the time was the flattening and other distortion of quartz pebbles in conglomerates. This phenom- enon Hitchcock had first noted in Rhode Island in 1832, but it was not until 1861, and in con- nection with the Vermont survey, that he was able to establish beyond question the accuracy of his first observation. He early became inter- ested in the problems of the drift, though he never quite accepted Agassiz's glacial theory. His paper on the river terraces of the Connecti- cut Valley, Illustrations of Surface Geology (1857), published by the Smithsonian Institu- tion, was for its time a classic. He was a prolific writer on a variety of subjects. He wrote five volumes and thirty-seven pamphlets and tracts on religious themes, the most notable being The Religion of Geology and Its Connected Sciences (1851); three volumes and as many tracts on temperance; fourteen volumes, five tracts, and some seventy-five papers on botanical, miner- alogical, geological, and physical subjects, and twenty-seven others, including a tragedy, Eman- cipation of Europe; or the Downfall of Bona- parte (1815), which during his principalship of the Deerfield Academy was "acted with great success before his neighbors" (C. H. Hitchcock, post, 134, 139). His Elementary Geology, pub- lished in 1840, passed through thirty editions and was then revised. In 1863 he published Rem- iniscences of Amherst College. Hitchcock is pictured as the typical New Eng- land clergyman of his day, a trifle stern, digni- fied, and smoothshaven. His ability is nowhere better shown than in his skilful handling of so delicate a question as that relating to geology and the Scriptures. Since he had nearly ruined both health and eyesight early in his career by overwork, it is remarkable that he did so much Hitchcock and did it so well. He was married in 1821 to Orra White of Amherst, an artist of ability who drew many of the illustrations for her husband's works. Six of the children born to them lived to maturity, and two, Edward and Charles Henry CM-V.], became distinguished in the fields of education and geology respectively.

HITCHCOCK, EDWARD (May 23, 1828- Feb. 15, 1911), educator, first professor of phys- ical education in an American college, was born at Amherst, Mass., of sturdy New England stock, a son of Professor, later President Ed- ward Hitchcock [#.#.]> of Amherst College, and of Orra (White) Hitchcock, an educated and profoundly religious woman. Almost his entire life was spent in the beautiful valley about Am- herst and along the Connecticut River. He grew up a healthy, active youth, developed in body largely by the many chores required of him but fond of the simple sports of the times. The phys- ical benefits from these early years were evident in his vigorous, virile manhood. He had no pa- tience with effeminacy in young men. He at- tended Amherst Academy, Williston Seminary, and Amherst College, where he graduated in 1849. After completing his medical course at Harvard in 1853, ne taught natural sciences and elocution at Williston Seminary until 1860, when, deciding to devote his life to the study of comparative anatomy, he went to England to become the private pupil of Sir Richard Owen of the British Museum. On his return to Amer- ica in 1861 he was unexpectedly called to the head of a recently organized "Department of Hygiene and Physical Education" at his alma mater, a position which he held for half a cen- tury. His acceptance of this call changed the whole course of his life. Credit for the origin of this department, which was put on an equal- ity with the others in the college, belongs to President Stearns, but the laying of the founda- tions of a department previously unknown in American colleges must be attributed to Hitch- cock. His precedents were the modern developments in popular, school, and military gymnastics in Germany, Sweden, Denmark, and England; the gymnastic program, of Charles Follen and Charles Beck [qq.v.] in Cambridge, Mass., and
