236 DEPARTMENTS 



In paleontology, the most important collections are .the Calvin collec- 

 tion of paleozoic fossils; a large collection of Coastal Plain fossils, prin- 

 cipally from the Cretaceous of New Jersey, the Eocene of Alabama and 

 Maryland, and the Miocene of Maryland and Virginia ; the Permo-Car- 

 boniferous series from Kansas and Russia, and the coal plants of Iowa, 

 Illinois, and Pennsylvania. 



In applied geology the department possesses comprehensive series of 

 lead and zinc ores with their characteristic gangue minerals from Joplin, 

 Missouri, and from the Iowa-Wisconsin area; copper and iron from the 

 Lake Superior region, Butte, Montana, Bisbee, Arizona, Brigham Canon, 

 Utah, and from the celebrated localities in the Ural mountains; copper, 

 manganese, and silver from Butte, Montana; lead, silver, and gold from 

 Colorado, Nevada, and California. 



The laboratory is supplied with four Bausch and Lomb petrographical 

 microscopes; one Fuess, medium model petrographical microscope; one 

 Bausch and Lomb photo-micrographic apparatus for transmitted or inclined 

 or vertically reflected light; one Bausch and Lomb binocular miscroscope 

 for the examination of sands, drillings, etc., with camera; one Zeiss ?e- 

 fractometer for determination of refractive indices of liquids; one Ward 

 mineral dresser ; one hand goniometer ; one set Preston's celluloid crystal 

 models ; one set Krantz selected wood models, exhibiting complicated 

 forms. The working equipment also includes one thousand thin sections 

 of the common rock-forming minerals selected and arranged according to 

 Rosenbusch, the collections selected to show the various representative 

 characters of minerals and rocks; one section slicing machine; complete 

 apparatus for mineral separations by heavy solutions; and apparatus for 

 doing all kinds of photographic work. A considerable number of instru- 

 ments for reconnaissance and field work in Geology are owned by the de- 

 partment. 



The lecture equipment comprises a Hitchcock's geological map of the 

 United States; one set of Kiepert's physical maps; numerous maps and 

 charts of the United States Geological survey and of the Mississippi River- 

 commission; and an elaborate series of lantern slides and photographs.
