LECTURES.

A course of lectures has been established in this department for the purpose of bringing to the knowledge of students, in the most vivid manner, recent developments in professional practice. Prominent engineers of Minneapolis and Saint Paul will give lectures in this course. J. T. Fanning, Hydraulic Engineer; F. W. Cappelen, City Engineer, Minneapolis; W. de la Barre, Chief Engineer St. Anthony Water Power Company; C. F. Loweth, Sanitary Engineer; A. W. Munster, Bridge Engineer, and George L. Wilson, First Assistant City Engineer, Saint Paul, have consented to contribute each along the line of his specialty.

MECHANICAL ENGINEERING.

The work of this course may be divided into three principal lines; theoretical engineering, experimental engineering and manual training, or the mechanic arts.

THEORETICAL ENGINEERING.

The course in theoretical engineering consists of the study of pure mathematics followed by the applied principles in the mechanics of engineering; pure mechanism or kinematics which traces the motion of connected parts without reference to the causes of motion, work done or energy transmitted; and machine design, in which the strength of parts and the proportioning of machinery is studied and actual designs and problems worked

out.

The subject of pure mechanism is supplemented in the drawing room where the successive positions of moving parts and the graphical solution of problems may be laid down on paper. In the last year of the course the study of thermodynamics is given by lectures, recitations and problems on the nature of heat and the measurement of its effect on fluids; generation of steam and the graphics of heat engines are considered, and the principles

of mechanics and thermo-dynamics as applied to the design and construction of steam engines, turbines and other motors are investigated.

Opportunity for the student to specialize is given by offering an elective study throughout the senior year.

EXPERIMENTAL ENGINEERING.

The work in experimental engineering begins with the investigation of the materials used in engineering. Their physical qualities are tested, the theory of strength of materials is applied, and the results compared with the results of the tests.

The instruments of precision used in mechanical tests are calibrated; practice is given on the preparation of tables, curves of efficiency, and the correction and determination of constants; the power given out by motors and the efficiency of mechanism and of boilers are measured; the methods of scientific and commercial tests are investigated.

A course in experimental physics also extends through the junior year.

MECHANIC ARTS.

In the drawing rooms the student receives practice in freehand drawing, shading, lettering and sketching parts of machines; also correct methods for producing mechanical drawings.

The shop work in this department aims to acquaint the student with the methods of modern manufacturing establishments, and enable him, as far as possible, to acquire skill in the processes.

The wood-working and pattern-making course is intended to embody the application of tools and practical methods to the work, and the proper construction of patterns for parts of machines. This is supplemented by instruction in the moulding and founding of these parts in brass and iron.

In the forge shop the student is instructed in welding, forming various shapes in iron, and in the making and tempering of hand and machine tools. The instruction in the machine shop is intended to give the student familiarity with the tools and operations of the modern machine shop, by the construction of parts or the whole of a machine and the making of machine tools.

THE MECHANICAL LABORATORY

Is supplied with power, and contains a variety of apparatus for experimental purposes, among which are the following: A 50,000pound Olson testing machine, which can be adapted for compressive, tensile, transverse, torsion and shearing tests. Other pieces of apparatus, designed by the department, are used in connec

tion with the testing machine in making tests of full sized beams, up to 25 feet in length. An extensometer, for use in connection with tensile tests, is capable of accurately measuring extension to one ten-thousandth of an inch. There is a Riehle cement tester for ascertaining the tensile strength of cements; a dynamometer for measuring transmitted power; an oil testing machine; standard scales; a pair of very accurate and highly finished test gauges registering pressure up to 300 pounds; a test pump for pressure gauges; a pump for testing boilers; a mercury column for calibrating steam gauges and indicators; and other apparatus for making mechancial tests; a dynamometer for determining the power of lathe tools, and a ten-horse power experimental steam engine and a steam pump for use in hydraulic investigations. A friction brake; a throttling, super-heating and separating tank; calorimeters; pyrometers; revolution counters; tanks; steam engine indicators; gauges; thermometers; a water motor and a Worthington water meter; a Wheeler condenser with air pump, and other instruments required for complete steam engine and boiler tests or for use in experimental work.

The department has a very fine skeleton pressure gauge, and a number of sectional working models, presented by the manufacturers, among which may be mentioned, a Dawes steam pump, marine steam pop-valve, Westinghouse engine air brake valve, triple valve and a Van Deutzen jet-pump.

THE SHOPS.

The basement of the Engineering building is occupied by the mechanical laboratory, machine and vise shop, and wood working shop; the wing by the engine and boiler room, forge shop and foundry.

The shops are equipped with tools which represent the best American practice. Each shop will accommodate from ten to twenty students at a time.

The instruction given is based on the "Russian system," in which the leading idea is to teach principles rather than to produce objects of commercial value. It is believed that the greatest progress can be made in a given time by this method, as the student proceeds, by a carefully planned series of exercises, from the simplest to the most difficult operations, learning the process but avoiding the repetition of the ordinary shop. So far as is consistent with this system the work is adapted to parts of some machine or structure in common use, and after finishing the exercises referred to above, the class will build some complete machine or structure, as a review and application of the preceding work.'

Shop work is required of students in mechanical and electrical engineering, and carpentry is required of students in all the courses in the college.

The engine and boiler room is provided with an automatic cut-off engine of modern type, capable of developing thirty-five horse power. A steel boiler of ample size, furnished with a feed pump injector, and all necessary fittings for conducting efficiency tests, supplies steam for the engines and laboratories.

The machine and vise shop contains speed lathes, engine lathes of various sizes, planer, shaper, universal milling machine, vertical drill press, emery tool grinder, a Brown & Sharp cutter and reamer, grinder, grinding attachment to lathe, ten benches with vises, surface plates, a set of Bett's standard gauges, taps, dies, reamers, arbors, drills, chucks and other hand tools and accessories for practice in machine, tool and vise work. The small tools are kept in a tool room and issued on the "check" system. The shop for pattern making and general wood work contains benches with vises and tools, lathes and lathe tools, an improved universal sawing machine for pattern making, etc., a jig saw, planer, boring machine, grindstone and other tools for use in the courses in carpentry and pattern making.

The forge shop is provided with a portable hand forge, stationary forges with anvils and sets of tools, a blower, and exhaust fan, hand drill press, drills, taps, dies, sledges, swages and other tools generally used in blacksmithing.

The foundry contains an eighteen inch cupola, brass furnace, core oven, moulding tools, benches, ladles, crucibles and all of the tools and material ordinarily needed in moulding and casting iron, brass or white metal.

Regular students pay a fee of three dollars and special students a fee of five dollars for each term of shop work.

DRAWING ROOMS.

The general drawing room is furnished with drawing tables for the use of classes in elementary drawing. A considerable collection of prints, drawings and models, including a full set of Schroeder's models for descriptive geometry is at hand for reference. Two additional drawing rooms contain tables, cases, etc., for students in advanced work in all the courses of study comprised in this College.

Adjoining the drawing rooms are printing and dark rooms fitted with complete apparatus for duplicating drawings by the "blue print" process and for photography.

Another dark room exclusively for photographic work has been fitted up on the first floor.

Rooms in Pillsbury Hall are equipped with a constantly increasing collection of papier mache models, casts, drawings and charts for use in the instruction in freehand drawing.

SPECIAL APPARATUS.

Besides a number of pieces of apparatus described in connection with the drawing rooms, mechanical laboratory, etc., there is a set of standard weights and measures furnished by the U. S. Coast and Geodetic survey. The set embraces: 1. A yard scale divided to inches and tenths, with a matrix for end measurement. 2. Weights from one grain to twenty-five pounds. 3. Liquid measures-a pint, a quart and a gallon. 4. Dry measures -a quart, a half peck, a peck and a half bushel. A table of correction for errors due to temperature, etc., accompanies the set.
