MEMORIAL OF C. H. HITCHCOCK G7 



On leave of absence from Dartmouth for parts of each year from 1870 

 to 189G, Professor Hitchcock was lecturer in geology for Mount Holyoke 

 College. In 1880-81 he additionally taught geology and zoology at 

 Williams College and in the Virginia College of Agriculture and the 

 Mechanic Arts. 



He received the degree of M. A. in course at Amherst in 1859, the 

 lionorary degree of Ph. D. from Lafayette College in 1870, and that of 

 LL. D. from Amherst College in 1896. 



Since 1856 he was a member and fellow of the American Association 

 for Advancement of Science, during half a century a nearly constant at- 

 tendent at its meetings and participant in its proceedings, and in 1883-4 

 was a vice-president, in charge of its section of geology. He was a mem- 

 ])er of local scientific societies in Portland, Maine; Boston, New York, 

 Philadelphia, and St. Louis, and also of the Imperial Geological Institute 

 of Vienna. He took a leading part in the organization of the Geological 

 Society of America, and earlier prepared reports and maps for several 

 meetings of the International Congress of Geologists. 



Between 1860 and 1870 Professor Hitchcock engaged largely as a 

 mining geologist in examination and estimation of the quantity and value 

 of mineral deposits for mining companies, traveling in Nova Scotia, 

 Xew Brunswick, Quebec, the New England States, New York, New 

 Jersey, Pennsylvania, and southward to Alabama. Subsequently he ex- 

 amined the phosphate beds of South Carolina, Florida, and Eedonda 

 Island of the West Indies, the gold fields of eastern Oregon, the Chalce- 

 dony Park of Arizona, the Grand Canyon of the Colorado, and the 

 Yosemite and Yellowstone parks. In 1883, 1886, and 1898 he visited 

 the Hawaiian Islands for studies of their volcanoes. 



The geological survey of New Hampshire may justly be regarded as 

 liis most prominent work. The formations are principally crystalline 

 schists and igneous rocks, and the areas best studied in detail are the 

 White Mountains and the Ammonoosuc mining district. Each of the 

 sections previously surveyed across Vermont was continued east through 

 this State, and the abundant rock specimens collected were placed on 

 exhibition with sectional drafts of the stratigraphy in the Dartmouth 

 College museum, a duplicate series being placed in the American Museum 

 of Natural History, New York City. 



Connected with this survey, a meteorological station was establisherl 

 on the summit of Mount Washington. J. H. Huntington, principal
