and reducing the triangulation; the principles of projecting maps; the methods employed in running parallels and meridians. The apparatus consists of a 13-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. Half of fall te>m, 5 hours a week.

Professor BAKEB.

Required: Math., 4; General Engineering Drawing, 1, 2, 3 ; Civil Engineering, 1, 2; Descriptive Astronomy, 2. 7. Practical Astronomy.—Is given by 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 three 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. Half of fall term, 10 hours a week-. Professor BAKER. Bequired: Math., 4; General Engineering Drawing, 1, 2, 3; Civil Engineering, 1, 2; Descriptive Astronomy, 2. 8. Bridges.—The instruction in bridges occupies two terms. The first—bridge analysis—is devoted to the calculations of the sirains in the various forms of bridge trusses, by algebraic and graphical methods, consideration being given to weights of bridge and train, and force of wind. The second—bridge design—is devoted to designing bridges, proportioning sections, and working out of details. Each student designs and makes a full set of drawings of a bridge. The apparatus consists of a series of full size joints and connections of a modern iron railroad bridge, numerous models of bridges, a large collection of drawings, photographs and lithographs of bridges. DuBois's Strains in Framed Structures. Winter and spring terms, 5 hours a week in the former and 10 in the latter. Professor BAKER. Required:. Mechanics, 1, 2.
