tion and construction of stations; the method of measuring the angles and reducing the triangulation; the principles of projecting maps; the methods employed in running parallels and meridians. The apparatus consists of a 12-inch alt-azimuth instrument reading to single seconds, a precise level, aneroid and mercurial barometers, three wooden base rods, a comparator, a steel tape with level, thermometer, and spring balance. Problems are solved in barometrical, trigonometrical, and precise leveling, and in reading horizontal angles. Fallt erm} half study.

Bequired: Math. 4; General Engineering Drawing 1, 2, 3, 4; Civil Engineering 1, 3; Descriptive Astronomy 2. 7. PKACTICAL'ASTRONOMY.—Lectures, recitations, and practice. The object is to familiarize the students with those principles of practical astronomy employed in extended surveying operations, and also to train the student in methods of exact observations. The apparatus consists of an observatory with five isolated stone piers; a 12-inch alt-azimuth instrument reading by micrometers to single seconds, both of altitude and azimuth; an astronomical transit: three chronometers; two sextants; two solar transits; and a set of meteorological instruments. The problems include the adjustments of all the instruments, and the determination of time, latitude, and azimuth by the several methods. Loomis's Practical Astronomy. Fall term, half study. Professor BAKEE. Bequired: Math. 4, General Engineering Drawing 1, 2, 3, 4; Civil Engineering 1, 3; Astronomy 2. 8. BRIDGES.—The instruction in bridges occupies two terms. (1) The first—bridge analysis—is devoted to the calculations of the strains in the various forms of bridge trusses, by algebraic and graphical methods, consideration being given to weights of bridge and train, and f otce of wind. (2) The second—bridge design—is devoted to designing bridges, proportioning sections, and working out details. Each student designs and makes a full set of drawings of a bridge. The apparatus consists of a series of full sized joints and connections of a modern iron railroad bridge, numerous models of bridges, a large collection of drawings, photographs, and lithographs of bridges. Johnson's Modern Framed Structures. Winter and spring terms. Professor BAKER. Bequired: Math. 2, 4, 6, 7, 8, 9; General Engineering Drawing 1, 2, 3, 4; Theoretical and Applied Mechanics 1, 2; Architecture 6.
