40 Illinois Industrial University. pattern making. Patterns are finally made, from which are cast pieces in iron, brass, etc., to be worked in the subsequent shops, In the 2d, the student uses the forge and performs the various elementary operations, such as drawing, upsetting, bending, •welding, etc. In the 3d, there is first a course of free-hand bench work, the cold-chisel and file being the only tools. After the hand and eye are sufficiently trained, fitting is begun, and the square, bevel, i"ule, compasses, and other auxiliary bench tools are used. Pieces are then fitted together by the file, with surfaces carefully finished. In the 4th shop the ordinary machine tools of the machine shop are used. The first practice employs these machines with their cutting tools or bits, in common operations, such as turning cylinders, disks, grooves, and fillets; boring, drilling, hand-turning, milling, planing, etc. Following this is a course of practice in fitting and finishing, in which calipers, rules, etc., are introduced, and many of the various fittings employed in machinery are produced. Lectures are given in which the most favorable forms and manipulation of cutting tools and auxiliary appliances are explained. Previous to the shop work, drawings of the pieces are made by the student, and the exact thing to be done is indicated; thus mistakes are avoided and practice facilitated. The designing of such machine elements as pulleys, journal boxes, cranks, stuffing boxes, etc., cultivates a knowledge of proportion, and of its proper representation on paper. This course of elementary practice fits the student for the advanced shop practice in designing and construction of complete machines undertaken later in the course. STUDIES. The studies are given by the year and term in the tabular view of the course. The order there indicated should be closely followed, that the student may avoid interference of his hours of recitation. The following is a detailed view: PURE MATHEMATICS, FIRST YEAR. Trigonometry.—Plain and spherical. Fundamental relations between the trigonometrical functions of an angle or arc; relations between the functions of different angles or arcs; construction
