The lectures of the first two years in Mechanical Engineering are the same as those for Civil Engineering; but, in the classes for engineering drawing, special attention is given to the design of machine details.

In the third year lectures will be delivered on-The theory of the steam engine, including the consideration of wire drawing, cylinder condensation, steam jacketing, multiple expansion, and the determination of the most economical point of cut-off. The design of steam boilers. Gas, oil and air engines. The design and construction of turbines, water wheels and water engines.

The construction of continuous current electrical machinery. Alternating current machinery. The design and preparation of working drawings of generators, transformers, and other alternating current apparatus. Instruments and appliances used in electrical testing.

Discussion of the design, equipment and management of hydraulic and steam power stations for electric lighting, traction, and power distribution. Long distance transmission of power by electricity. Special applications of electricity to industrial purposes, such as the driving of workshop tools, cranes, pumps and other machinery by means of electric motors.

a

LABORATORY PRACTICE.-Students are required to attend course in laboratory practice, including The testing of materials, the practical management and testing of gas engines, steam engines and boilers, the measurement of the flow of water, the testing of hydraulic motors, the determination of the power absorbed by different machines, and various tests of the value of lubricants.

61. ENGINEERING DRAWING.

All students in Engineering are required to attend lectures in the following subjects, and to continue their practice till they have satisfied the lecturers as to their proficiency-The use of drawing instruments. Systems of lettering, writing and colouring on engineering and surveying plans, charts, &c. Conventions for the representation of topographical and orographical features.

The course for the first two years includes-The practical design of machine details, engines, boilers, and machinery. Drawing out valve diagrams, and diagrams of stresses in structures. Design of bridges, roofs and buildings.

In the third year students are required to prepare an original set of working drawings, having reference to the particular branch of engineering which they have taken up in that year.

THE ENGINEERING LABORATORY.

The Engineering Laboratory is fitted with apparatus for systematic instruction in the experimental methods which are used to determine the physical constants of the chief materials of construction and the numerical data employed in engineering calculations. The laboratory is provided with a testing machine, capable of exerting a force of 100 tons, especially arranged for accurate tests of large sized specimens such as beams and columns; also with a machine of 100,000 pounds capacity, with an accumulator and various descriptions of apparatus for measuring strains, autographic recording apparatus, micrometers, verniers, &c. Both machines are adapted for testing in tension, compression, crossbreaking and torsion. Various pieces of apparatus for testing cements, wire, the lubricating value of oils, and the calorimetric value of fuels. An experimental compound condensing engine and locomotive boiler, provided with indicators, brakes, calorimeters, and all necessary apparatus for testing the evaporative efficiency and power developed under various conditions of working. Apparatus for the determination of the friction with materials of the form and with the velocities common in engineering work, the measurement of the energy spent in driving machines, and the useful work done by them.
