STATE WATER SURVEY STAFF EDMUND J. JAMES, PH.D., LL.D., PRESIDENT. Associate Professor EDWARD BARTOW, PH.D., DIRECTOR. Professor SAMUEL WILSON PARR, M.S., Consulting Chemist. WALTER GELVIN BAIN, A.B., M.D., Assistant Bacteriologist. The Chemical Survey of the waters of the state was begun in the latter part of September, 1895. In June, 1897, the Legislature authorized the continuance of the work and directed the Trustees of the University to establish a chemical and biological survey of the waters of the state. The purpose of the Survey is to collect facts and data concerning the water supplies of the state; to make such chemical and biological examination and analyses as shall serve to demonstrate their sanitary condition; to determine standards of purity of drinking waters for the various sections of the state, and to publish the results of these investigations. The Survey is a division of the department of chemistry of the University of Illinois, and special laboratories are equipped in the Chemical Laboratory for conducting the work. Analyses of water for citizens of the state are made on request. THE STATE ENTOMOLOGIST'S OFFICE STAFF EDMUND J. JAMES, PH.D., LL.D., PRESIDENT.

JAMES ALEXANDER WEST, A.M., Entomological Assistant. 904 West Stoughton Street, U. The work of the State Entomologist's Office has been done at the University of Illinois since January, 1885; and by legislative enactment in 1899 it was permanently established at the University, the Trustees of which are required by that act to provide for the Entomologist and his assistants such office and laboratory rooms as may be necessary to the performance of their duties. It is the function of this officer to investigate the entomology of Illinois, and particularly to study the insects injurious to the horticulture and agriculture of the state, and to prepare reports of his researches and discoveries in entomology for publication by the state. He is also required to inspect and certify annually all Illinois nurseries, and to maintain a general supervision of the horticultural property of the state as respects its infestation by dangerous insects and its infection with contagious plant diseases. Twenty-three reports have now been published by the Entomologist, ten of them since the transfer of his office to the University. THE STATE GEOLOGICAL SURVEY STAFF EDMUND J.

The Forty-fourth General Assembly passed an act, in force July 1, 1905, providing for the establishment at the University of Illinois of a Bureau, to be known as the State Geological Survey. Rooms were placed at its disposal in the Chemical Laboratory, and the work was soon taken up. The Bureau is under the control of a commission, of which the President of the University is an exofficio member. The purpose of the Survey is primarily the study and exploitation of the mineral resources of Illinois. Field parties are organized for the investigation of clay, coal, stone, artesian water, cement materials, road materials and general scientific investigations. The Bureau is charged also with the duty of making a complete topographical and geological survey of the state. The topographical work will lead to the publication of a series of bulletins and of maps, eventually covering the entire state. The laboratory work is done in connection with various department laboratories of the University. The equipment includes a working library, maps and a rapidly growing collection, illustrating the geological and the economical resources of the State. GENERAL DESCRIPTION OF COURSES Following the description of each course of instruction will be found the necessary requirements, if any, for admission to that particular course. Careful attention must be given to these requirements and to the sequence of studies thus indicated. For instance, under Architecture 4, for students of the College of Engineering, page 218, there are required "Physics 2a and 2b," and "Architecture 2 and 3." Turning now to these subjects, it is found that physics 1 and 3 are the major course of one year, architecture 2 is wood construction, and architecture 3 is metal construction. All these subjects must be satisfactorily passed before admission may be had to the class in architecture 4. In case a course not required for graduation is selected by less than five students, the right to withdraw the same for the semester is reserved. Graduate courses of instruction are described under the various subjects, as a rule after the undergraduate courses. They are numbered upward from 100. Other courses may often be arranged by the professors in charge to meet the special requirements of students. Credit is reckoned in semester "hours," or simply "hours." An "hour" is either one class period a week for one semester, each class period presupposing two hours' preparation by the student, or the equivalent in laboratory, shop, or drawing room. The semester, the days, and the hour of the day during which each course is given, and the number of credit "hours" per semester for which the course counts, are |
