sentences:  Special arrangements had to be made with the Parks Department to have a gatekeeper on duty during the nights when the telescope was in use, and for him to supervise entry and exit of public and cars, and ensure no-one was left in the park after the observatory was locked up.This meant that all children had to be accompanied by an adult.For this reason the Council placed the Observatory under the administrative control of the Parks Superintendent, under whom it remained until reorganisation brought a transfer to the Museums Department.
