chisel andfilebeing 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 thefile,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, discs, 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 manipulations 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 pulleysjjournal 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.

TECHNICAL STUDIES.

Kinematics and Principles of Mechanism.—Relative motion of points

in a system of connected pieces ; motion independent of force ; velocity ratio ; investigation of motion of elementary parts of machines, as friction and non-circular wheels in rolling contact.cams and curves in sliding contact geer teeth ; gearing chains ; escapements ; link work. Prime Movers.—The theory and useful effects of turbine water-wheels and best form of the parts for high efficiency. Other water-wheels and wind-wheels. Application of thermodyamics in the study of heat engines. Relative economy of different engines. Mill-work and Machinery.—Trains of mechanism, studied with reference to their resistence and efficiency ; best forms for transmission of power for short or great distances; forms of the parts for securing desired results in power and velocity; elastic and ultimate strength of parts. Machine Drawing.—Working drawings of original designs; finishing in water colors, and in line shading; details for shop use according to the practice of leading manufacturers.
