Detailed plans for the fifty-second session of the Harvard Summer School, which will be held from July 10 to August 19, were announced yesterday by the Director in charge.

About 125 different courses are offered on 25 subjects. They are University courses and nearly all are accepted subject to the established regulations, to count as half-courses for the degrees of Bachelor of Arts, Associate in Arts, and Bachelor of Science. The method of instruction varies according to the nature of the subject. Daily lectures are given in each subject, in some cases two lectures each day. With the lectures are combined conferences and recitations, laboratory exercises under supervision written papers, etc.

The summer courses are intended primarily to provide University instruction for teachers, and were arranged in the belief that short-term study can be made most effective by concentration on a single subject. A student is advised to enroll regularly in only one course, and to give to that for six weeks his whole time and effort. Long experience has given increasing confidence in this intensive method of summer study, and those in charge believe that only in this way can a large subject be adequately covered in so short a time.

The rules for undergraduates as to the number of courses and credit are as follows: Undergraduates who have an average record of B or better during the previous academic year or who, for special reasons, have obtained the consent of the Dean of the College may count toward a degree two summer courses, the equivalent of one whole course. All others may count for credit only one half-course.

The courses are open to both men and women, with the exception of courses in Architecture, Engineering, and Geology, which are open to men only. No entrance examination is required for admission to any of the courses.

Professor John Tucker Murray '99 is Director of the Summer School, the faculty of which will number about 100 men. Of these, approximately one-third will be visiting professors and instructors from various schools and colleges throughout the country.

The tuition fee for a course varies from $10 to $50, the usual amount being about $20. Residence and board during the summer session is offered in Gore, Standish, and Smith Halls. Gore and Standish will be reserved for women and Smith Halls for men students.

Applications for rooms are filled in the order received.

Further information and pamphlets on the summer session may be obtained from the Secretary of the Summer School in 19 University Hall.
