Washington public schools go to war. The public schools of Washington, D.C., like those in most other sections of the country, have revised their curricula to fit the pupils for fuller participation in the war effort. They have gone all-out for the Program of Civilian Defense and at the Margaret Murray Washington Vocational School, courses in home-making and the preservation of foods are now taught all young women.
