Recent attacks on Cliffies have spurred the Radcliffe administration to strengthen security measures in the vicinity of the Quad, Helen H. Gilbert, acting president of Radcliffe, disclosed Tuesday.

Three parts of a new four-point protection plan are already in effect, she said. The city has installed powerful mercury street lights on Shepard and Walker Streets, and Radcliffe Buildings and Grounds have placed new lights in the Quad area. In addition, two Cambridge policemen will drive around the Quad and nearby off-campus houses at fairly frequent intervals each night.

The police will be supplemented by four night watchmen who are being transferred from indoor duty to outdoor patrol.

Watchmen Will Use Radios

As soon as the equipment is available, the night watchmen will be supplied with shortwave radio boxes, giving them direct contact with the University switch-board. Harvard policemen already have a similar radio set-up.

Mrs. Gilbert, together with Wilma Kirby-Miller, academic vice-president; Arthur D. Trottenberg '48, administrative vice-president; Ralph B. Gates, Director of Radcliffe Buildings and Grounds; and the Harvard and Cambridge police forces drew up this plan after the attempted knifing of a Radcliffe student and another attack on a head resident and student last month caused a review of the whole security operation.

The night watchmen are Radcliffe employees, sworn in as constables. They carry no firearms, but the new radio boxes will enable them to notify armed Cambridge police in the area within a few minutes of any emergency.

Radcliffe has hired additional night watchmen to replace those taken from inside the dormitories.

Mrs. Gilbert outlined the new security measures in a meeting with dormitory senior residents; house masters; College deans; Mary H. Winslow, Director of Residence; Trottenberg, Gates, and Mrs. Kirby-Miller. The senior residents will, in turn, call dorm meetings to advise Cliffies to increase their safety precautions.
