(4)Except on the occasion of the visit of the Board of Visitors no visitor can claim to be accompanied on his rounds by the Superintendent, Deputy Superintendent or Assistant Superintendent.[Visitors are not permitted without the express consent of the Superintendent to interview more than one prisoner at a time. Anything in the nature of a meeting or conference whether for the discussion of political topics or the ventilation of jail grievances, is strictly prohibited.] [P.G. letter No. 16489 (H. Jails), dated 11th June, 1926.]All private interviews with the prisoners will normally be subject to a time limit of ten minutes. If a visitor wishes to exceed this limit, he should give his reasons for doing so in writing to the Superintendent.
