Mechanical Engineering comprises the design

construction, and operation of machinery, the design of manufac: turing plants, and all branches of industrial production. The mechanic a] engineer’s education should be similar to that of the civil engineer with the addition of a knowledge of the theory and practice of machine construction. Electrical Engineering is a branch of mechanical engineering and includes the application of electricity to mechanical and industrial pursuits, as derived fron: some other source of energy. - Mining Engineering is a combination of the three preceding branches as applied to the discovery and operation of mines, the building of mineral working plants, and treatment of ores. Military Engineering deals entirely with the arts of war, the design, construction and maintenance of fortifications, machines of defense and attack, ordnance, and the surveying of country in preparation for military operations. Marine Engineering is partly military and partly civil, embracing naval architecture, building and operating. of ships and naval acce ories. In the military sense, it comprises the construction of war ve els and_ the construction and placing of torpedoes, submarine mines, etc. Sanitary Engineering consists of the construction of sewers and drains, providing for the cleaning of city streets and the disposal of garbage and sewage, reclaiming of swamps, and overcoming of all conditions tending to interfere with public health. The education and training of the engineer in modern times heave called for the establishment of technical schools and courses in engineering in the large colleges and universities, These schools provide the student with the theories of mathematics, mechanics, and engineering and by means of extensive laboratory and outside work provide him with practice in the design, construction, and use of modern engineering appliances.
