Dean Leighton and Dean von Stade spoke out yesterday against the freshman riots of last Sunday and Tuesday nights. Both emphasized that disciplinary action will be taken against any student violating the regulations of the College.

"The approach of final examinations and several unfortunate recent episodes lead me to warn students that they are individually responsible for a knowledge of Faculty regulations," Leighton stated. College rules prohibit possession of explosives or the playing of "boisterous music" after 10 p.m.

Some students have been placed on probation following Sunday's disturbance in the Yard, with the individual punishment determined by the offense. Scholarship students placed on probation will lose their scholarships. Von Stade indicated that all students caught breaking College regulations would be brought before the Dean's office.

As reasons for opposing the mass gatherings, von Stade cited the chance for injury caused by firecrackers, thrown bottles, and other missiles, and the danger of fire in the dormitories.

"There are other ways of relieving tension than by holding mass gatherings," von Stade noted. He commented that students should "let off steam individually," rather than in mass groups. "If people act childishly, then we should treat them as children."

Dean Francis R. Brown warned Radcliffe house mothers yesterday afternoon to take special precautions to keep doors and windows locked during the evenings from Thursday to next Monday. Dean Brown stated that "panty-raids" might take place on these evenings.
