BUILDINGS AND EQUIPMENT OF SIBLEY COLLEGE. The buildings of Sibley College occupy a ground enclosed between East and Central Avenues, at the north end of the Campus, leased from the University for the purposes of the College, under an agreement with the late Hiram Sibley.

The two main buildings of the Sibley College are each one hundred and sixty feet long, fifty feet in width, and three stories in height. They contain museums, the reading-room, drawing-rooms, large and well-lighted lecture-rooms, and the rooms of the different professors. The workshops are placed in separate buildings and consist of a machine shop, a foundry, a blacksmith shop, and a wood-working shop. and include rooms devoted to the storage of tools. Besides these there is an additional building, one hundred and fifty feet by forty in dimensions, and two stories in height, occupied by the laboratories of the department of experimental engineering. At the bottom of Fall Creek Gorge is the house protecting the turbines which supply the power ordinarily required for driving the machinery of the College, and the electric apparatus for lighting the campus and the buildings, and, near it, a steam pumping station used as a reserve when the power of the hydraulic station is unequal to the demand for water supply. The large engine and dynamo room, containing all the engines and dynamos employed in lighting the University, is adjacent to the shops, and beside the boiler-room in which are placed the 200 H. P. boilers furnishing steam to these and the experimental engines.

The Collections of Sibley College are of exceptional extent, value, and interest. The principal room on the first floor of one building is devoted to the purposes of a museum of illustrative apparatus, machinery, products of manufacturing, and collections exhibiting processes and methods, new inventions, forms of motors and other collections of value in the courses of technical instruction. In this museum is placed a large Reuleaux collection of models of kinematic movements. Besides these are the Schroeder and other models, exhibiting parts of machinery, the construction of steam engines and other machines, and a large number of samples of machines constructed to illustrate special forms and methods of manufacture. Many of these machines and tools have been made in the University shops. The lecture rooms of Sibley College, each being devoted to a specified line of instruction and list of subjects, are each supplied with a collection of materials, drawings, models, and machines, especially adapted to the wants of the lecturer. The course of instruction in mechanical

engineering is illustrated by a fine collection of steam engines, gas and vapor engines, water-wheels and other motors, models and drawings of every standard or historical form of prime mover, or parts of machines, and of completed machinery.

The collections of the Department of Drawing and Art include a large variety of studies of natural and conventional forms, shaded and in outline, geometrical models, casts and illustrations of historical ornament, and remarkably fine collections of casts, of pattern and other art work.

The workshops are supplied with every needed kind of machine or tool, including lathes, and hand and bench tools sufficient to meet the wants of two hundred students of the first year, in wood-working; in the foundry and forge, all needed tools for a class of over one hundred and fifty in the second year; in the machine shop, machine tools from the best builders, and a great variety of special and hand tools, which are sufficient for a class of one hundred and fifty in the third year, and as many seniors and graduate students.

The Sibley College Mechanical Laboratories constitute the department of demonstration and experimental research of Sibley College, in which not only instruction, but investigation is conducted. They are supplied with the apparatus for experimental work in the determination of the power and efficiency of heat motors, and of the three turbines driving the machinery of the establishment; with a boiler-testing plant and instruments; and with twenty machines of the various standard types for testing the strength of metals, including machines of 50, 100, and 150 tons capacity; and one 60,000 and one 200,000 pound Emery machine, of extraordinary accuracy and delicacy. Sixteen steam-engines, nine air, oil, and gas engines, fourteen dynamometers, eight lubricant-testing machines, about fifty standard pressure guages and an equally numerous collection of steam engine indicators, together with other apparatus and instruments of precision employed by the engineer in such researches as he is, in practice, called upon to make, are collected here. A large hydraulic "plant" is employed for experimental purposes and for research. All the motors of the University, and its boilers, amounting to 1000 horse-power, are available for test trials. The steam-engines are set up, with the heavy lighting dynamos, adjacent to the boilers; among them a 200 H.P. experimental engine," and several of smaller power, including a 20 H.P. quadruple expansion experimental engine and steam boiler, designed and built by students, and arranged to use with steam at 500 pounds pressure, exhibiting an efficiency without precedent at its date.

The Laboratories of Electrical Engineering, including the apparatus of the Department of Electrical Engineering of Sibley College and also that available in the Department of Physics, comprehend many special collections of apparatus and equipment. In addition to large numbers of workings drawings of stations, "plants," motor and electrical machinery, there are extensive collections of experimental machinery and apparatus of research. These collections include a great number of large and small dynamos of arc and incandescent lighting types, including a five hundred light and a twenty-five light Edison, two Thomson-Houston, three Weston, a Ball, a Mather, a Waterhouse third brush, a Gramme, a Siemens and Halske, a six hundred and fifty light Westinghouse alternate current machine and its complement of converters, and a Westinghouse forty arc-light alternate with its full complement of lamps, and a ten H.P Laval turbine and dynamo; a variety of motors, including two ten H.P. automatic Sprague motors, a Brush five H.P. constant current, and a Tesla alternate current motor. Storage batteries are of the Julien, Gibson, Sorley, and other "accumulator" types; aggregating about 200 cells. There are also arc and incandescent lamps of all the various types, and commercial electric meters. The great tangent galvanometer and electro-dynamometers, and the potential instrument at the Magnetic Observatory, and the authorized copies of the British Association standards of resistance afford every facility for making measments in absolute measure of current, E.M.F., and resistance, with the highest attainable accuracy.

There are large numbers of ammeters, voltmeters, Wheatstone bridges, electro-dynamometers, electric balances, long range electrometers, etc., many constructed here, others purchased, for general use, and always kept in correct adjustment by comparison with the above standardizing apparatus. Apparatus is provided for all delicate testing, for the exact study and determination of alternate current energy, for conductivity and insulation tests, and for the determination of the properties of the magnetic materials. Means for making quantitative measurements are supplied through a well equipped photometer room for the photometry of arc and incandescent lamps; several Brackett cradle" dynamometers for efficiency tests of dynamos and motors; a rehostat of german-silver wire, for a working resistance, with a capacity ranging from twenty-two hundred ohms and four ampères to four-tenths of an ohm and three hundred ampères.
