PBAOTICB.

In the fall term of the second year, the class will solve numerous problems in distances, areas, etc., using the chain, compass, and plane table. During the winter term the student will have practice with all the engineering instruments, and solve problems with the transit, stadia, level, and sextant. In the spring term an accurate topographical survey of a locality is made by the class, in which the stadia and plane table are used as in the United States surveys. In the fall term of the third year the class will execute a project in railroad engineering, which will consist of preliminary surveys, location, staking out, drawings, computations of earth work, etc. The preliminary survey will consist in an examination of the locality, and in running tangent lines, with leveling and topographical sketching. The location will consist in running the line over the route decided upon, with all the necessary measurements and calculations for establishing the grade, setting slope stakes, etc. The drawings will include alignment, profile, plans, etc. A project in geodesy or higher engineering will be executed during the fall term of the senior year. During this term the students have exercises in practical astronomy.
