COLLEGE OF SCIENCE.

GEOLOGY.

95

In the department of geology four courses are offered. For those students who wish more than a general acquaintance with the subject a major course of one year is provided, covering thirty-six weeks of class room and laboratory instruction; and a supplementary course of twentytwo weeks is offered to those who select a geological subject as a thesis. Engineers who wish an acquaintance with those portions only of the science which bear most directly on their future work are offered a minor course of eleven weeks. A minor course of eleven weeks is offered to those desiring merely an outline of the most prominent facts and theories of geology, with some ideas of the methods by which the geologist arrives at his conclusions. i. Geology, Major Course. — (a) Dynamic Geology. The instruction given under this head is intended to familiarize the student with the forces now at work upon and within the earth's crust, modeling its reliefs, producing changes in the structure and composition of its rock masses, and making deposits of minerals and ores. A series of localities is studied in which great surface changes have recently taken place, with a view to ascertaining the character of the forces producing such changes, and the physical evidence of the action of like forces in the past. The subject is taught by lectures, and is abundantly illustrated by maps, models, charts, and views. (b) Petrographic Geology. The instruction under this topic is given by lectures and laboratory work. The subjects included are the classification of rocks, the methods used in their determination, the conditions governing the formation of each species, the decompositions to which they are liable, and the products of these decompositions. Each student is supplied with a set of blowpipe tools and reagents and a series of hand specimens covering all the common species of.rocks. (c) Historical Geology. The work on this subject is substantially an introduction to the history of geology as a science, and the developmental history of the leading geological doctrines. An attempt is also made to trace the history of each geological period, so far as may be done with the data in hand. (d) Paleontology. The scheme of instruction in this subject places before the student the classification adopted for those organic forms occurring as fossils, together with the succession of the various groups that occur in the strata, with the cause, as far as known, for
