GEOLOGY 



1. Elements of Geology. Lectures and recitations, supplemented 

 by excursions during the open season and by laboratory work 

 during the winter months. Three hours, either semester. Lectures. 

 M, IV, at 11; quiz sections, F, at 8, 9, 10, and 11. Museum 

 Lecture Room. Laboratory sections, M or W or F, 1-3 or 3-5; 

 or S, 8-10, or 10-12. Professor HOBBS, Assistant Professor 

 CASE, Mr. SCOTT, and assistants. 



2. Historical Geology. Three hours, either semester. Lectures, M, 

 IV. F, at 10. Laboratory work, one hour a week, Thursday after- 

 noon. Assistant Professor CASE and assistant. 



An outline history of the development of the continent and of 

 the appearance and extinction of plants and animals, from the 

 records in the rocks. 



35. Soil Geology. Three hours, second semester. M, IV, F, at 9. 

 Geological Laboratory. 



A comprehensive survey of the subject including the origin of 

 soils, their physical and chemical constitution, the influence of 

 climate on soil fertility, irrigation and drainage, tillage, fertil- 

 izers, etc., and a consideration of the regolith of the United 

 States in relation to geologic, physiographic, and climatic factors. 



MIIVERALOGY AND PETROGRAPHY 



1. Elements of Mineralogy. Lectures and laboratory work. Two 

 hours, either semester. Lectures, Tu, Th, at 11. Laboratory 

 work, two hours a week, to be arranged. Mineralogical Lecture 

 Room, T. H. Professor KRAUS, Mr. HUNT, and assistants. 

 This course includes the elements of crystallography, physical 

 and chemical properties, occurrence, uses, and determination of 

 the more common minerals. For this course a knowledge of 

 elementary inorganic chemistry is necessary. 



9. Lithology. Lectures and Laboratory work. Two hours, either 

 semester. Lectures, M, W, at 2. Laboratory work, two hours a 

 week, to be arranged. Mr. CLARK. 



The lectures include, aside from a review of the rock-forming 

 minerals, a discussion of the origin, modes of occurrence, alter- 

 ations, methods of determination, and uses of the more import- 

 ant rocks. In the laboratory the student is required to deter- 

 mine by means of the macro-physical properties a large number 

 of rock specimens. Numerous field excursions will also be 

 made in order to acquire facility in the rapid determination of 

 rocks in the field. Prerequisites, Mineralogy 1 and Geology 1.
