Site and Climate

The campus of the University of California, situated on the lower slopes of the Berkeley Hills, commands a splendid view over San Francisco Bay and the Golden Gate. Its 530 acres of land include a great variety of topography. From a hight of some 200 feet above the sea, the gentler slopes on which stand most of the University buildings merge into the bolder slopes of the hills and extend to about 1300 feet elevation. Beyond the campus boundary, and reached by excellent trails, the nearby summits of the hills rise to heights of 1700 to 1900 feet above the sea. Around three sides of the campus lies Berkeley, a city of homes, with a population of about 60,000. San Francisco is thirty-five minutes ride from the campus by electric train and ferry; street cars run to the business center of Oakland in twenty-five minutes.

The climate of Berkeley is well suited for uninterrupted university work. The records of the meteorological station maintained by the University covering a period of thirty years show an average temperature for June, July, and August of about 60°. The highest temperature for the day averages close to 70°, while the lowest temperatures of the nights average about 53°. These favorable temperature conditions are due to the marked prevalence of light southwest winds from the ocean, which give a distinctly invigorating character to the summer weather at Berkeley. "High fogs," which are a fairly frequent accompaniment of the ocean winds, serve further to moderate the temperature. Low fogs, often associated with a coastal climate, are relatively infrequent. On rare occasions the moist southwest wind is replaced by a dry north or northeast wind, and at such times the temperature rises during the hottest part of the day to between 85° and 90°. Temperatures around 95° have been noted a few times during the period of record. Owing to their low humidity, these land winds are almost never oppressive. The summer at Berkeley is practically rainless, though the month of June occasionally has showers of short duration. Out-of-door activities of every sort may be planned without fear of interruption by weather. A light overcoat will be found occasionally useful, especially during the cool evenings.

THE UNIVERSITY

The University of California (founded in 1868) is by the terms of its charter an integral part of the educational system of the state. At Berkeley are the Colleges of Letters and Science, Commerce, Agriculture, Engineering, and Chemistry; the Schools of Architecture, Education, and Jurisprudence, and the instruction of the first two years in the Medical School; at Mount Hamilton is the graduate Astronomical Department, founded by James Lick; in San Francisco are the Colleges of Law, Medicine (third, fourth, and fifth years), Dentistry, and Pharmacy; in Los Angeles are the Southern Branch and the Los Angeles Medical Department; at Riverside is the Graduate School of Tropical Agriculture; at La Jolla is the Scripps Institution for Biological Research; and at Davis is the University Farm. The University's income, 1919-20, for all purposes amounted to $5,844,464.13. The University is indebted to Mrs. Phoebe A. Hearst for permanent building plans, upon a scale appropriate and comprehensive. At Berkeley there are 385 principal officers of instruction and administration, together with assistants numbering about 500; fortythree departments of instruction; about 15,556 students in 1920-21, including the Summer Sessions of 1920; a library of 400,000 volumes aside from the volumes in the Bancroft collection; museums and laboratories; also the agricultural experiment grounds and station, which are invaluable adjuncts of the farming, orchard, and vineyard interests of the state. In San Francisco there are 265 officers of instruction, including demonstrators and other assistants; 721 students in 1920-21. In Los Angeles there are at the Southern Branch 102 officers of instruction and administration, 908 students in the Junior College and 1218 in the teachers' Tuition in the academic departments of the University during the fall and spring sessions is free to residents of California; non-residents pay a fee of $75 each half-year. Instruction in all of the colleges is open to all qualified persons, without distinction of sex.

LIBRARY

The General Library, housed in the building made possible by the bequest of the late Charles F. Doe, now contains more than 400,000 volumes. It is constantly augmented by donations and exchange and by large purchases of books with the income from the Michael Reese, Jane K. Sather, E. A. Denicke, Alumnus, Meyer, Carpentier, and other funds. Books are specially bought each year for the particular courses offered during the Summer Session. All Summer Session students may enjoy full privileges of the Library, including the drawing of books; and the hours of opening are the same as during the regular academic year.

The extensive Bancroft collection of manuscripts and books relating to Pacific Coast history is in process of arrangement. The major portion of the manuscripts has been calendered.

The resources of the Library are supplemented by borrowings from other libraries, and, similarly, the Library lends its books, under proper regulation, to other institutions.

Several of the departments of instruction have separately kept collections of books, useful for ready reference and classroom work.

MUSEUMS AND LABORATORIES

Psychological Laboratory. The equipment of the psychological laboratory includes the usual apparatus for demonstrations and for elementary experiments and mental measurements. The laboratory is also provided with a large number of special pieces of apparatus for investigations in the principal lines of psychological research, together with the necessary auxiliary instruments. There is a collection of printed forms and other materials for use in conducting mental tests with children and adults, apparatus for investigations in animal psychology, a colony of rats for this work, and a collection of models and charts of the brain and sense organs.

The psychology building contains rooms used as laboratories for instruction in experimental psychology; facilities for work with animals and for general research work; a shop where carpenter work may be done; battery and storage rooms; office research rooms for the members of the staff, and a seminar room. All the rooms are connected by switch board with low potential electrical current, and are served with 110 volt current, both direct and alternating. All of the larger classes meet in other buildings.

Although crowded during the regular term, the building offers excellent opportunities for research work during the summer.

The Physical Laboratories are located in South Hall. There are set apart rooms for elementary and for advanced work, for photometry, for spectroscopic research with a Rowland grating, for measurements in heat and in electricity, and for a workshop. The apparatus includes many instruments and standards for fundamental measurements from makers of the best reputation, and the laboratory employs two competent mechanicians, who are continually increasing the equipment from original designs. It offers good facilities to students who wish to pursue the study of physics beyond the limits of the prescribed courses, whether for the sake of physics itself or in connection with other subjects, like electrical engineering, astrophysics, the practical uses of polarized light, and physical chemistry. Such students may make special arrangements for using the laboratory.

Students' Observatory (Berkeley Astronomical Department). The equipment of the observatory consists of the following instruments: an eight-inch reflector, gift of the Hon. William M. Pierson, suitable for visual and photographic observations; a six-inch refractor with position micrometer; a five-inch refractor, with position micrometer, gift of Mr. and Mrs. Herman Oelrichs; a six-inch photographic telescope and a fiveinch photographie telescope with a three-inch guiding telescope, all equatorially mounted with driving clocks; a three and one-half inch Bamberg prismatic transit, with transit micrometer; a three-inch Davidson combination transit-and-zenith telescope; a two-inch astronomical transit; a two-inch altazimuth instrument; surveyors' transits with solar attachment; spectroscopes; a Pickering photometer; a Repsold measuring engine for measuring astronomical photographs; a Gaertner microscope for measuring spectrograms; electrochronographs; a Harkness spherometer; a level-trier; sextants; chronometers; a Rieffler sidereal clock; a Howard M. T. clock; all necessary electrical connections for recording time and determining longitude by the telegraphic method.

Visitors are received at the Students' Observatory on the first Saturday of each month, in the evening from 8 to 10 o'clock.

Chemical Laboratories. These laboratories are housed in a group of buildings, of which one is devoted entirely to the first-year course in chemistry. It contains ten small laboratories, each of which accommodates twenty-five students. It also contains the necessary storage, preparation, and distributing rooms.

The main chemistry building contains two large lecture rooms, laboratories devoted to instruction in organic chemistry and quantitative analysis, and a number of rooms devoted to research work.
