Serving as the first organized unit of college students to do defense duty with the Boston Information Center, about 300 Harvard men will be signed up tonight at 7 o'clock in Emerson Hall for work in a secret airplane report center. Operating in shifts, they will receive information from airplane spotters and filter stations, plot and map reports, and relay the information to military authorities.

Recruited by the War Service Committee with the cooperation of Clarence E. Walton, assistant librarian at Widener and instructor at the Boston Information Center, the student volunteers will have a month of instruction before going on duty.
