To facilitate practice in surveying, an area has been specially prepared in which the difficulties of plane surveying are presented to the beginner as he is able to meet them, and where he is taught practical methods of overcoming them. All possible distances, directions, areas, and elevations are accurately known ; hence the instructor knows beforehand the precise result which the student should obtain. Not a single problem or exercise is given in which there is wanting an absolute check upon the accuracy of the work. This is an incentive to the student and enables the teacher to show him the degree of accuracy attained and also to point out errors. For the Lecture Room.—The school has numerous models for illustrating its specialties, including models of bridges, roofs, joints, and connections; a large collection of drawings, photographs, and photo-lithographs of bridges, roofs, and engineering structures, numerous railway maps, profiles, etc; maps of government surveys, and plans and specifications. It has access to a complete set of lithographs of the lectures and drawings used in the government polytechnic schools of France. The industrial museum contains a large collection of building materials, of wood, brick, stone, and iron. The testing laboratory has a machine with a capacity of a hundred thousand tons for tension, compression, or bending; also a cement testing machine. The library is well supplied with the best and latest periodicals and books upon engineering subjects, to which the students have full access. PRACTICE. In the fall term of the second year the class solves numerous problems in distances, areas, etc., using the chain, compass, and plane table. During the winter term the students have practice with all the engineering instruments and solve problems with the transit, stadia, level, and sextant. In the spring term the class makes a topographical survey of a locality, using the stadia and plane table as in the United States surveys. In the fall term of the third year the class executes a project in railroad' engineering, which consists of pre-
