Mechanical Art and Design. 47 In designing the student begins with elements, and proceeds with progressive exercises till he is able to design and represent complete machines. MECHANICAL AST AND DESIGN. An elementary course of shop practice has been carefully arranged, to familiarize the student with the forms of the parts of machines, and the mode of producing them. He is made familiar with all the ordinary cutting tools for iron or wood; with the form and condition for most effective work; with the machines and appliances by which they are put in action, and the instruments by which desired dimensions of product are obtained. This practice is obtained in the Mechanical Laboratory, and represents five different shops, viz.: 1—PATTERN MAKING. 2—BLACKSMITHING. 3—FOUNDRY WORK. 4—BENCH WORK TOR IRON. 5—MACHINE TOOL WORK FOR IRON. In the 1st, the practice consists in planing, turning, chiseling, etc., in producing true surfaces in various forms in wood, and also in combining pieces by glue joint, etc., preliminary to correct 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, the process of moulding and casting are fully illustrated. In the 4th, 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, rule, compasses, and other auxiliary bench tools are used. Pieces are then fitted together by the file, with surfaces carefully finished. In the 5th 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, discs, grooves, and fillets; boring, drilling, hand-turning, milling, planing, etc. Pol-
