Total value of all gifts, $5,500.

In addition to the above, about five hundred dollars' worth of apparatus has been loaned to the electrical department of the University, for special work.

No. 2.

In 1891 the University purchased for use upon its Schenectady testing plant, a standard 85,000-pound locomotive. This engine, now known as Schenectady No. 1, continued to be used for the instruction of students, and for scientific research until the spring of 1897, when it was decided to replace it by one which would better represent the progress in locomotive design which had been achieved during the preceding six years. As a result of this decision we exchanged the old engine for Schenectady No. 2. The new locomotive has been designed with special reference to the purpose it is to serve. It has 69-inch drivers and weighs 107,000 pounds. Its boiler carries 250 pounds pressure, and its cylinder arrangement is such that it may readily be converted from a simple to a compound locomotive. This plant is nowhere duplicated in the world.

General Railway Laboratory.

The general laboratory equipment for railroad work has been greatly increased during the past year. An addition, fifty by one hundred feet, has been made to the main laboratory.

The new room is occupied by several machines for testing the strength of engineering materials, varying in capacity from 30,000 pounds to 300,000 pounds; by an elaborate piece of apparatus for studying the resistance offered by the atmosphere to the motion of railway trains; by a machine for testing brake-shoes, and by an airbrake testing rack.

The brake-shoe testing machine and the air-brake testing rack were designed by committees of the Master Car-Builders' Association; the one to serve in a study of the behavior of brake-shoes of various materials, when applied to cast-iron and to steel-tired car wheels, and the other to disclose the action of triple valves.

In addition to its machine equipment, the railway laboratory contains an important exhibit of railway materials, including nine typical steel car trucks, a large exhibit of truck and body bolsters, of brake-beams, car-couplers, and signaling apparatus.

Railway Engineering and Manage

We have for several years offered work covering a considerable variety of railway subjects, but the great ment. demand which has recently come from the railways of the country for men trained in technical schools has induced us to establish a course of railway engineering and management. This was put into operation at the beginning of the present year. The work has been done in the main by our regular staff, but we have been able, through the kindly interest shown by the leading railways of the country in the enterprise, to secure the services of some of their most prominent men as special lecturers. Among those who have served us in this way are the following: J. T. Brooks, Seeond Vice-President Penn. Lines West of Pittsburg; Frederic A. Delano, Superintendent Freight Terminals, C. B. & Q. Ry. Co., Chicago; Addison C. Harris, Attorney at Law, Indianapolis; Melville E. Ingalls, President of Big Four System, Cincinnati; John W. Noble, Ex-Secretary of the Interior, St. Louis, Mo.; Robert Quayle, Superintendent Motive Power and Machinery, C. & N. W. Ry. Co., Chicago; Godfrey W. Rhodes, Superintendent Motive Power of Machinery, C. B. & Q. Ry. Co., Aurora, Ill.; Angus

Sinclair, Editor Locomotive Engineering, New York City; Arthur M. Waitt, General Master Car Builder, L. S. & M. S. Ry. Co., Cleveland.

These have done their work for us without compensation, and have generally paid their own traveling expenses. The fact that these men, among the busiest in the world, have been willing to serve the State in this way is evidence that they must have a high appreciation of the value of the work done at Purdue University.

8 Official Testing at Purdue.

The facilities which have been brought into exist ence at Purdue for advancing engineering research, and the high character of the results which from time to time have been issued from the laboratories, have received the generous attention of several representative engineering associations of the country.

The American Society of Mechanical Engineers has not only expressed its approval of Purdue's system of locomotive testing, but has given a description of the practice followed at Purdue an important place in its code.

The two associations representing the mechanical interests of American railways have also, in various ways, made use of the facilities of the laboratory, and have sought to sustain its work by financial and other assistance. The American Railway Master Mechanics' Association has, for example, on three occasions appointed committees to officially represent it at the laboratory during investigations in which it had a special interest. During the past year the Master Car-Builders' Association has deposited at Purdue apparatus valued at several thousand dollars, which is to become a part of the permanent equipment of the laboratory, and which will lend itself to investigations of great scientific value. As this apparatus is not duplicated, its presence in the Purdue laboratory is a mark of real distinction.

Again, the records of both railway associations and the proceedings of the several railway clubs, particularly during the past year, bear testimony to an appreciation which is as complimentary as it is generous.

These evidences of good will, officially displayed by the leading engineering societies of the country, are, it is believed, to be accepted as a fair measure of the value of the equipment which has

been brought together, of the skill with which it is employed, and of the unprejudiced value of judgments rendered.
