WILL GIVE NAUTICAL COURSE

Astronomy S2a, a course in navigation and nautical astronomy, will be given in the Summer School this year, according to an announcement just issued. This course corresponds to Astronomy 2a which is given during the regular College term.

The ground covered by the instruction is substantially that of the "American Practical Navigator," Bowditch. A considerable part of the time will be devoted to the theory and practice in the use of nautical instruments, including the chart, compass--corrections and adjustments--lead, log, and sextant in the determination of the position of a ship at sea. The course also instructs in the determination of time, as well as the latitude and longitude, by means of the sextant.

Men who have taken Astronomy 2a have found the course particularly valuable in fitting them for officer ratings in the Naval Reserve. Those who take the course, and later supplement their knowledge by practical experience at sea for a year or so will probably be fitted for an officership on one of the ships of the new merchant marine.

Dr. H. T. Stetson, who is now instruct-in the class in nautical training which has just been established at the Students' Astronomical Laboratory, win give Astronomy S2a this summer.

Half Course Toward Degree.

The course presupposes an acquaintance with the elements of trigonometry. It will be accepted as a half-course for the A.B., A.A., or S.B. degree, but for students in the College it cannot be counted in addition to Astronomy 2a. This summer the instruction is to be given five days each week at 9 o'clock. The fee for the course, including the privileges of the Astronomical Laboratory, is $25.
