questions of public welfare, in questions of investment, or in the pursuit of personal health and pleasure. Thus there would be studied such practical matters as the generation, distribution, metering and sale of gas and electricity; hydro-electric and irrigation developments; water and sewerage systems; heating and ventilation; illumination; sanitation and hygiene; the chemistry and physiology of foods; electric and steam traction; steam and gasoline engines for power or pleasure vehicles.

Such courses are quite possible if based upon introductory courses of sophomoric grade. The ordinary high-school courses do not supply a sufficiently advanced basis. The introductory courses should be especially outlined in connection with their continuations. The advanced courses would best be presented under the direction of three instructors broadly trained in their respective subjects of electrical engineering, chemical engineering and sanitary engineering, in cooperation with a doctor of medicine, an economic geologist, and the pure science instructors of biology, physics and chemistry. The work of all the courses should be of the same standard as that for similar subject matter in the best technical schools. The subjects should be presented by illustrated lectures, class recitations from text-book assignments, exercises in problems, excursions to illustratory industries or public improvements, and written reports. The success of such courses depends much upon the teaching staff. The need of some such courses, however, is steadily increasing.

In the main the solution of the present educational problem may be said to demand more liberal arts in technical schools, and equally, more practical science in colleges.
