The Cambridge City Council took another step yesterday towards restoring law and order to Harvard Square.

Just a week after it asked for a study on the use of dogs in the Square, the Council called for assignment to the area of additional city police--their salaries to be paid for by the University.

Councillor Alfred E. Vellucci sponsored the order, and the Council passed it unamiously.

University Should Pay

Vellucci emphasized that the University should pay for the added police in the Square. "The responsibility must be absorbed by Harvard and the cost born by the University," he declared.

Councillor Bernard Goldberg introduced an amendment to the Vellucci order asking Cambridge police, University police, and "security forces" from Radcliffe and M.I.T. to form a committee "to review the various and sundry problems that exist in the Harvard Square area."

Vellucci said this was not enough, however, and spread before the Council an entirely new idea for police coordination in the city.

Under Vellucci's scheme, which was not formally proposed and therefore did not come to a vote, Cambridge would create a Public Safety Commissioner, who could mobilize all the city's private police forces.

In the event of an emergency, the heads of the University police, M.I.T. police, bank security guards, and all other private forces would be responsible to the Public Saftey Commissioner. He would coordinate the movements of all private and public officers in the entire city.

Under the plan, University police would receive the full powers of Cambridge police and could arrest students outside the usual perimeter of Harvard jurisdiction.
