come students and do all in their power to furnish moral and social uplift. But there is still lacking to the mass of students a form of social intercourse which shall possess the elements of freedom, unconventionality and mental and moral uplift. This problem arises in all educational institutions and is acknowledged to be a serious one. Certainly the authorities in charge can not ignore its importance, nor neglect attempts to solve it. Such a want would be met at Purdue by the provision of a University Union or club which should combine the features of. a modern gymnasium with ample provision for exercise and bathing, with a building containing rooms for recreation, reading, meetings of the students' organizations, and as a general meeting place for all members of the University, including the faculty, upon a fraternal and democratic basis. Such a building should be of size aud equipment to permit the giving of University functions of social character, and accommodate mass meetings of the student body. It would serve a purpose in harmonizing University interests and affording innocent and helpful forms of recreation to the students such as nothing else could do. When one comprehends the positive value of such a building to the University life, it seems impossible to wait until financial conditions or the generosity of some friend will permit the fulfillment of the hope. The work of the instructors has increased in proportion to the number of students. They have been compelled to deal with more classes and with a larger number in each class, which has not only increased their hours of classroom instruction but added very seriously to the work of examining reports, correcting exercises, etc. The working hours with classes extend from 8 a. m. to 5:30 p. m. from Monday morning to Saturday noon, and under this schedule many instructors are obliged to work regularly evenings in order to keep up the current work of their departments. Their zeal and devotion under these conditions is worthy of recognition. RETIREMENT OF PROFESSOR STEVENS. Professor Moses Cobb Stevens, who served the University for twenty-one years in the capacity of Registrar, Librarian and Professor of Mathematics, expressed a desire to be relieved of active duties at the close of the year. The Trustees, at their annual meet ing in June, granted this request and voted to retain Professor Stevens on the rolls as Professor of Mathematics, emeritus. Both the trustees and faculty passed appropriate resolutions with reference to his long and able service to the University. Probably no member of the faculty has so endeared himself to successive generations of students and colleagues as Professor Stevens, and his retirement, crowned with the honor and affection of his pupils and associates, was an event of unusual interest. DEGREES GRANTED. During the academic year one hundred and seventy-six degrees were conferred as follows: Baccalaureate Degrees― Bachelor of Science Bachelor of Science in Agriculture... 19 10 Bachelor of Science in Mechanical Engineering 37 Several certificates were also granted to students who had completed courses in the Winter School of Agriculture. No better evidence as to the character of the work performed by the candidates for these degrees can be given than a list of the titles of the theses prepared by them as a condition for graduation. These theses in all cases represent a piece of individual study, research or investigation, the key to which was given in a problem assigned by the department in which the work was performed. It will be observed that the subjects studied touch upon a wide range of topics, many being of great importance to the public welfare. The inevitable inference is that men and women trained in so many diverse lines can hardly fail to render a large measure of intelligent and helpful service toward the progress of their respective communities.

The most notable change in the course of study has been the introduction of a course in telephonic engineering. This step was taken in response to the increasing demands by telephone interests for men trained in the particular branch of electrical engineering pertaining to telephony. Investigation has disclosed the fact that students completing the ordinary courses in electrical engineering must devote upwards of two years additional work to acquiring the special details of tele phone practice before they are sufficiently equipped with the knowledge which is valuable to manufacturers and consumers of telephone material. It is confidently expected that the courses now offered by Purdue University will largely take the place of the two years practical employment or apprenticeship and will enable the engineering graduate of this department to at once fill telephoni positions demanding special qualifications. |
