Y c; REPORT OF THE PRESIDENT To THE MEMBERS OF THE CORPORATION: In accordance with the by-laws of the Corporation I have the honor to submit to you a report upon the work of the Institute, during the preceding year, based on infor- mation received from heads of departments, together with reports from other administrative officers with reference to the work of their special departments. THE CORPORATION. The term for which Messrs. Matthew C. Brush, Francis W. Fabyan and Franklin T. Miller were elected Term Members expired in June. In place of these retiring members the Corporation elected Messrs. Andrew G. Pierce, Jr., Salmon W. Wilder and John Lawrence Mauran upon nomination by the Alumni Asso- ciation. The Corporation at its October meeting elected Mr. Francis W. Fabyan a Life Member. THE FACULTY. During the year the Faculty has suffered loss through the resignation of Professor A. E. Kennelly, and through the retirement of Professor F. J. Moore and Professor Henry Fay. Other losses have been occasioned by the resignation of Assistant Professors H. U. Faulkner, A. H. Gilkeson, John M. Heath and David A. D. Ogden. Additions to the Faculty have been made as follows: Herbert B. Dwight has been appointed Professor of Electrical Machinery; Joseph W. Barker, Associate Professor of Elec- trical Engineering; F. S. Dellenbaugh, Jr., Associate Professor of Electrical Design; Dr. Charles Terzaghi, Lecturer and Research Associate in the Department of Civil Engineering; Lieutenant Harold L. Milan and Lieutenant Anderson T. W. Moore, Assistant Professors of Military Science and Tactics. Associate Professors G. L. Hosmer and R. G. Tyler have been advanced to the grade of Professors. 9 10 MASSACHUSETTS INSTITUTE OF TECHNOLOGY Assistant Professors J. B. Babcock, 3d, L. F. Hamilton, A. F. Holmes, C. S. Robinson, R. H. Smith and Hale Sutherland have been advanced to the grade of Associate Professors. The following have been promoted to the grade of Assistant Professors: E. L. Bowles, G. L. Clark, O. G. C. Dahl, P. Franklin, W. H. Jones, M. Knobel, C. E. Lansil, J. T. Norton, and W. N. Seaver. DEPARTMENT OF CIVIL ENGINEERING. A noteworthy change in the undergraduate courses of the Civil Engineering Department during the past year was the addition of a series of lectures on Aerial Surveying and Mapping to the course in Surveying. This course was given by Gerard T. Matthes, M. I. T. '95, through the courtesy of the Fairchild Aerial Surveys, Incorporated, of which Mr. Matthes is consulting engineer. These lectures were open to all Institute students in Civil Engineering, attendance being required of students in the second year class in Surveying. The method of aerial surveying has come very rapidly into use, not only in various government surveys but in private work. A soil stack with a head equivalent to that which would be required in a three-story building, with necessary devices for measuring pressures and discharges has been constructed. This makes it possible to extend further the investigations in that branch of Sanitary Engineering which has to do with the construction of buildings, the practice of which has been left very largely to empirical formulae and tradition in the past. During the present year an important addition is being made to the graduate work by the introduction of a course in soil mechanics, a subject in which little, if any, formal instruction has been given in the past. The establishment of this course marks an important development in that part of civil engineering concerned with foundations, dams, retaining walls and other problems where a knowledge of the physical properties of the soil are essential. The work will be in charge of Dr. Charles Terzaghi of Czecho-Slovakia, a man of wide experience in the field of soil mechanics and REPORT OF THE PRESIDENT recently acting head of the Civil Engineering Department of Roberts College, Constantinople. Dr. Terzaghi has done much notable work in this important but obscure field and has an international reputation. The fourteenth session of the Summer Surveying Camp was held during the summer of 1925 with an attendance of ninety-one students. The site is an admirable one for the purpose, the buildings are well planned and carefully kept, the camp is a credit to the Institute. The question of establishing at the Camp an accurate base line and a series of stations for the most accurate tri- angulation is being discussed. There is need in this country for a few well-trained men in this
